DETAILED DESCRIPTION OF THE EMBODIMENTS
[0057] In order to make the foregoing objects, features and advantages of the present application more apparent and understandable, a detailed description of the specific embodiments of the present application is set forth below with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the concept of the present application, and therefore the present application is not limited by the specific embodiments disclosed below.
[0058] FIG. 1 is a perspective view of a decorative tree 1000 according to an embodiment of the present application. The decorative tree 1000 may include a decorative mesh 30 and a tree stand 10. The decorative tree 1000 will be detailed described below, as well as the decorative mesh 30 and the tree stand 10.
[0059] Referring to FIGS. 1 and 3, in an embodiment, the decorative tree 1000 is illustrated, for example, as a decorative lighted tree. The decorative mesh 30 may, for example, be a flexible woven mesh, so that ornaments (such as small pendants, light beads, etc.) may be hung thereon to provide a good decorative effect. Furthermore, the decorative mesh 30 may, for example, be a light mesh, which is woven from a plurality of light strings 301 and a plurality of cords 302. Specifically, when expanded, the decorative mesh 30 has a substantially conical structure, i.e., a space enclosed by the decorative mesh 30 gradually decreases in diameter from bottom to top. In other embodiments, when expanded, the decorative mesh 30 may have other structures, such as a cubic structure or a cylindrical structure. In this embodiment, as shown in FIG. 1, the decorative mesh 30, which has a conical structure when expanded, is illustrated. Specifically, each of the light strings 301 is substantially circular. Diameters of the circular light strings 301 decrease gradually from bottom to top. The circular light strings 301 with gradually decreasing diameters are connected one by one by means of the respective cords 302. Moreover, the plurality of cords 302 may be spaced apart in a circumferential direction of the light strings 301. Alternatively, in other embodiments, each of the cords 302 is substantially in a shape of a circular ring. Diameters of the circular cords 302 decreases gradually from bottom to top. The circular cords 302 with gradually decreasing diameters are connected one by one by means of the respective light strings 301. Moreover, the plurality of light strings 301 may be spaced apart in a circumferential direction of the cords 302.
[0060] Referring to FIGS. 1, 3 and 4, the tree stand 10 includes a pole assembly 110, a support arm 120, a first mounting member 130 and a second mounting member 140. The support arm 120 is connected to a bottom end of the pole assembly 110 and configured to be connected to a bottom of the decorative mesh 30. The first mounting member 130 is mounted at a top end of the rod assembly 110 and has a locking portion 131 (see FIG. 9). The second mounting member 140 is movably disposed on the pole assembly 110 and configured to be connected to a top of the decorative mesh 30. The second mounting member 140 has an engaging portion 141 (see FIG. 10). The engaging portion 141 is capable of being locked with the locking portion 131 to limit movement of the second mounting member 140 relative to the pole assembly 110.
[0061] The support arm 120 is disposed at the bottom end of the pole assembly 110 and connected to the bottom of the decorative mesh 30, and the second mounting member 140 is movably disposed on the pole assembly 110 and connected to the top of the decorative mesh 30, so that a state of the decorative mesh 30 can be changed by changing a position of the second mounting member 140, allowing the decorative mesh 30 to be switched between an expanded state and a collapsed state. The first mounting member 130 is mounted at the top end of the pole assembly 110 and has the locking portion 131, and the second mounting member 140 has the engaging portion 141 which is capable of being locked with the locking portion 131, so that when the second mounting member 140 is moved to the top end of the pole assembly 110, the user can interlock the locking portion 131 with the engaging portion 141 by operation, so as to fix the second mounting member 140, and therefore, the decorative mesh 30 is maintained in the expanded state to play a good decorative role. Accordingly, the user can operate the first mounting member 130 or the second mounting member 140 to unlock the locking portion 131 from the engaging portion 141, thereby separating the second mounting member 140 from the first mounting member 130. When the second mounting member 140 is separated from the first mounting member 130, the second mounting member 140 automatically moves to the bottom end of the pole assembly 110 under pushing force or gravity, so as to bring the decorative mesh 30 into the collapsed state, and thus, volume of the decorative tree 1000 can be reduced. In other words, when it is required to unfold the decorative tree 1000 for decorative effect, the user may quickly pull the second mounting member 140 to move to the top end, and then interlock the locking portion 131 with the engaging portion 141 by operation. When it is required to reduce the volume of the decorative tree 1000 for storage or transportation, the user may unlock the locking portion 131 from the engaging portion 141 by operation. It can be seen that the above tree stand 10 can simplify the folding process of the decorative tree 1000 and improves folding efficiency.
[0062] Configurations of the pole assembly 110, the first mounting member 130 and the second mounting member 140 will be described below, one by one, in conjunction with the drawings.
[0063] Referring to FIGS. 3 and 4, in an embodiment, the pole assembly 110 generally includes a fixed support tube assembly 111 and a movable support tube assembly 112. The support arm 120 is connected to the fixed support tube assembly 111. The movable support tube assembly 112 is detachably disposed on the fixed support tube assembly 111 to allow the pole assembly 110 to switch between a use state (see FIG. 3) and a non-use state (see FIG. 10). The first mounting member 130 is mounted on the movable support tube assembly 112. Specifically, as shown in FIG. 3, when the pole assembly 110 is in the use state, the fixed support tube assembly 111 is connected to and is coaxial with the movable support tube assembly 112, and the second mounting member 140 is movable in an axial direction of the pole assembly 110, i.e., the second mounting member 140 can reciprocate between the fixed support tube assembly 111 and the movable support tube assembly 112. As shown in conjunction with FIGS. 4 and 10, when the pole assembly 110 is in the non-use state, the movable support tube assembly 112 is separated from the fixed support tube assembly 111, in other words, the movable support tube assembly 112 is removed from the fixed support tube assembly 111. In this way, the height of the tree stand 10 (i.e., the decorative tree 1000) can be reduced, thereby reducing the volume of the tree stand 10 (i.e., the decorative tree 1000) and facilitating transferring or storing the decorative tree 1000.
[0064] In an embodiment, one of the fixed support tube assembly 111 and the movable support tube assembly 112 includes a first abutting end 111a, and another of the fixed support tube assembly 111 and the movable support tube assembly 112 includes a second abutting end 112b. For example, the fixed support tube assembly 111 includes the first abutting end 111a (see FIG. 4), and the first abutting end 111a is, for example, tapered. The movable support tube assembly 112 includes the second abutting end 112b. The first abutting end 111a is detachably inserted into the second abutting end 112b by a predetermined length, so that the movable support tube assembly 112 and the fixed support tube assembly 111 are detachably connected to form the pole assembly 110. In this way, the efficiency of disassembling and assembling the pole assembly 110 can be improved by the means of insertion. In another alternative embodiment, both the first abutting end 111a and the second abutting end 112b are provided with a thread, so that the first abutting end 111a can be threadedly connected to the second abutting end 112b to improve stability and reliability when the fixed support tube assembly 111 is connected to the movable support tube assembly 112.
[0065] In an embodiment, at least one of the fixed support tube assembly 111 and the movable support tube assembly 112 includes at least two support tubes 1121. Specifically, in this embodiment, as shown in FIG. 4, the movable support tube assembly 112 includes at least two support tubes 1121. The at least two support tubes 1121 are either in detachable connection or in telescopic connection. It should be noted that the detachable connection includes, but is not limited to, a direct insertion connection, a threaded connection, or a rotating connection, etc., and the telescopic connection refers to that two adjacent support tubes 1121 are sleeved together so that a length of the movable support tube assembly 112 can be changed by means of telescoping. More specifically, in this embodiment, as shown in FIGS. 6 and 7, the movable support tube assembly 112 includes two support tubes 1121. The two support tubes 1121 are in a detachable insertion connection. In order to avoid the two support tubes 1121 from being easily lost after being separated from each other, an elastic wire 113 is connected between the two support tubes 1121. Specifically, referring to FIG. 7, one of the support tubes 1121 has an end forming the above second abutting end 112b, and another end forming a third abutting end 1121a. Another of the support tubes 1121 has an end configured to support the first mounting member 130, and another end forming a fourth abutting end 1121b. The third abutting end 1121a is detachably inserted into the fourth abutting end 1121b by the predetermined length, and in this case, inner cavities of the two support tubes 1121 are in communication with each other. More specifically, as shown in FIG. 7, the elastic wire 113 is disposed in the inner cavities of the two support tubes 1121. Two ends of the elastic wire 113 are connected to the two support tubes 1121 respectively. In this way, when it is required to shorten the length of the movable support tube assembly 112, the two support tubes 1121 are respectively pulled to move away from each other by hands to separate the fourth abutting end 1121b from the third abutting end 1121a, and then the two support tubes 1121 are placed parallel to each other. During this process, the elastic wire 113 is stretched and then bent. In this embodiment, the height of the tree stand 10 (or the decorative tree 1000) can be adjusted in a larger range by providing the plurality of support tubes 1121. Through the detachable connection or the telescopic connection, the tree stand 10 (or the decorative tree 1000) can be folded to have a small volume, which in turn makes it more convenient for storage or transportation.
[0066] Optionally, in another illustrated embodiment, the fixed support tube assembly 111 and the movable support tube assembly 112 are also telescopically connected, i.e., the movable support tube assembly 112 is inserted in the fixed support tube assembly 111, so that the movable support tube assembly 112 and the fixed support tube assembly 111 cooperate with each other to form a telescopic pole structure. Specifically, a diameter of the fixed support tube assembly 111 is greater than a diameter of the movable support tube assembly 112, and the fixed support tube assembly 111 is sleeved on the movable support tube assembly 112. In this way, the height of the tree stand 10 (i.e., the decorative tree 1000) can be adjusted by means of telescoping.
[0067] Referring to FIGS. 7 to 11, in an embodiment, one of the locking portion 131 and the engaging portion 141 is a limiting protrusion 131a, and another of the locking portion 131 and the engaging portion 141 is a limiting groove 141a. Specifically, in this embodiment, the locking portion 131 is the limiting protrusion 131a, and the engaging portion 141 is the limiting groove 141a. As shown in FIG. 11, the limiting groove 141a is curved. Two ends of the limiting groove 141a form a starting end 1411 and a locking end 1412, respectively. The second mounting member 140 has a substantially annular structure, such as a hollow cylinder or a hollow truncated cone. The second mounting member is movably sleeved on the pole assembly 110. The second mounting member 140 can reciprocate in the axial direction of the pole assembly 110, and be rotatable around a center axis of the second pole assembly 110. The first mounting member 130 is rotatable relative to the second mounting member 140, so that the limiting protrusion 131a is capable of reciprocating between the starting end 1411 and the locking end 1412. Specifically, when the limiting protrusion 13 la is engaged to the locking end 1412, the first mounting member 130 is fixed relative to the second mounting member 140. More specifically, the starting end 1411 extends through an end face of the second mounting member 140 facing the first mounting member 130, i.e., the starting end 1411 extends through an upper end face of the second mounting member 140. The limiting groove 141a extends in a curved shape along an outer periphery of the second mounting member 140, and the locking end 1412 of the limiting groove 141a is located below the upper end face of the second mounting member 140. A sidewall of the limiting groove 141a is provided with an engaging protrusion 1413. The engaging protrusion 1413 is located at the locking end 1412, and is configured to abut against the limiting protrusion 131a to limit the limiting protrusion 131a to the locking end 1412. More specifically, the limiting groove 141a has a first sidewall 1419a at least partially facing a lower end face of the second mounting member 140, and a second sidewall 1419b facing the first sidewall 1419a. The engaging protrusion 1413 is disposed on the first sidewall 1419a of the limiting groove 141a and protrudes towards the bottom end of the pole assembly 110.
[0068] It should be noted that the above wording the first mounting member 130 is rotatable relative to the second mounting member 140 may include three possible implementations as follows: the first mounting member 130 is rotatable around the center axis of the pole assembly 110, but the second mounting member 140 is not rotatable relative to the pole assembly 110; or the second mounting member 140 is rotatable around the center axis of the pole assembly 110, but the first mounting member 130 is not rotatable relative to the pole assembly 110; or the first mounting member 130 and the second mounting member 140 are both rotatable around the center axis of the pole assembly 110. Specifically, in this embodiment, the first mounting member 130 mounted on the top end of the pole assembly 110 is rotatable around the center axis of the pole assembly 110, and whether the second mounting member 140 is rotatable around the center axis of the pole assembly 110 is not specifically limited thereto.
[0069] In this embodiment, as shown in FIG. 11, the second mounting member 140 includes a locking sleeve 142 and a connecting base 143 which are connected to each other. Both the locking sleeve 142 and the connecting base 143 are annular and are movably sleeved on the pole assembly 110. Specifically, the locking sleeve 142 is substantially in a shape of a cylinder, and the connecting base 143 is substantially in a shape of a truncated cone, and the locking sleeve 142 is connected to an upper surface of the connecting base 143. The engaging portion 141 is disposed on the locking sleeve 142. When the engaging portion 141 is the limiting groove 141a, the limiting groove 141a extends through at least an outer side surface of the locking sleeve 142. The starting end 1411 of the limiting groove 141a extends through an end face of the locking sleeve 142 facing away from the connecting base 143. Specifically, as shown in FIGS. 3 and 11, the connecting base 143 has a connecting portion 1431. The connecting portion 1431 is configured to be connected to the top of the decorative mesh 30. Optionally, the connecting portion 1431 may be, for example, a connecting through-hole. The cords 302 on the top of the decorative mesh 30 extend through the connecting through-hole to form a knot by means of knotting. The knot abuts against an opening edge of the connecting through-hole to realize connection between the decorative mesh 30 and the second mounting member 140. In other embodiments, after extending through the connecting through-hole, the cords 302 at the top of the decorative mesh 30 may be connected to a blocking member (not shown). The blocking member is configured to abuts against the opening edge of the connecting through-hole to limit the cords 302 from separating from the second mounting member 140.
[0070] In an embodiment, a plurality of connecting portions 1431 are provided. The plurality of connecting portions 1431 are spaced apart in a circumferential direction of the connecting base 143. The number of connecting portions 1431 is equal to the number of cords 302. In this way, each of the cords 302 can be connected to the second mounting member 140 through the corresponding connecting portion 1431. In addition, a plurality of (e.g., 2, 3, or 4, etc.) locking portions 131 and a plurality of (e.g., 2, 3, or 4, etc.) engaging portions 141 are provided. The number of locking portions 131 is equal to the number of engaging portions 141. The plurality of locking portions 131 are spaced apart in a circumferential direction of the first mounting member 130, and are symmetrically distributed. The plurality of engaging portions 141 are spaced apart in the circumferential direction of the second mounting member 140 and are symmetrically distributed. In this way, the stability of the connection between the second mounting member 140 and the first mounting member 130 can be improved.
[0071] Referring to FIGS. 8 to 11, in an embodiment, the tree stand 10 further includes an elastic member 150 (e.g., a spring). The elastic member 150 is disposed between the first mounting member 130 and the pole assembly 110. The elastic member 150 is configured to provide an elastic force that enables the first mounting member 130 to move away from the bottom end of the pole assembly 110. In this way, when the limiting protrusion 131a is engaged to the locking end 1412, the elastic member 150 drives the first mounting member 130 to move upward in the axial direction of the pole assembly 110, that is, allows the limiting protrusion 131a to abut against the first sidewall 1419a of the limiting groove 141a facing the ground (i.e., facing the bottom end of the pole assembly 110), and thereby, the limiting protrusion 131a can ultimately be limited in a limiting space 1414 enclosed by the engaging protrusion 1413 and the first sidewall 1419a of the limiting groove 141a. Therefore, when the second mounting member 140 is required to be locked, the second mounting member 140 can be moved to the top end of the pole assembly 110, then, the first mounting member 130 is pressed and rotated, so that the limiting protrusion 131a enters into the limiting groove 141a from the starting end 1411 and quickly moves to the locking end 1412. Then, the first mounting member 130 and the second mounting member 140 are released, and the limiting protrusion 131a is limited in the limiting space 1414 thereby realizing the locking between the locking portion 131 and the engaging portion 141. As a result, it is ensured that the second mounting member 140 can be stably disposed at the top end of the pole assembly 110, so that the decorative mesh 30 can be maintained in the expanded state to provide a good decorative effect. More specifically, the elastic member 150 may also be configured to assist in separating the first mounting member 130 from the second mounting member 140, and the detailed description thereof will be described below.
[0072] In other embodiments, the elastic member 150 may be omitted. When the limiting protrusion 131a is engaged to the locking end 1412, after the second mounting member 140 is released, the second mounting member 140 moves downward in the axial direction of the pole assembly 110 under gravity, so that the limiting protrusion 131a can be engaged in the limiting space 1414.
[0073] In an embodiment, when the locking portion 131 is the limiting protrusion 131a and the engaging portion 141 is the limiting groove 141a, the limiting protrusion 131a may be disposed on an outer side of the first mounting member 130, and correspondingly, the limiting groove 141a may be disposed on an inner side of the second mounting member 140 (i.e., the locking sleeve 142) or extend through the inner and outer side of the second mounting member 140. Alternatively, the limiting protrusion 131a may be disposed on the inner side of the first mounting member 130, and correspondingly, the limiting groove 141a may be disposed on the outer side of the second mounting member 140 (i.e., the locking sleeve 142) or extend through the inner and outer sides of the second mounting member 140. Still referring to FIGS. 8 to 11, in this embodiment, the first mounting member 130 is substantially in a shape of a cone. A side of the first mounting member 130 facing the second mounting member 140, i.e., a bottom surface of the cone, is provided with a rotation hole 132. The locking portions 131 are disposed on an inner wall of the rotation hole 132, in other words, the locking portions 131 are disposed on the inner side of the first mounting member 130. Specifically, a diameter of the rotation hole 132 is greater than a diameter of the locking sleeve 142. In this way, at least a portion of the locking sleeve 142 can be received in the rotation hole 132, and the locking sleeve 142 can be connected to the first mounting member 130 by the limiting protrusion 131a cooperating with the limiting groove 141a.
[0074] More specifically, a bottom wall of the rotation hole 132 is provided with a guide post 133. The top end of the pole assembly 110 is provided with a support cylinder 160. The support cylinder 160 is detachably connected to the pole assembly 110. In this embodiment, the support cylinder 160 is in a threaded connection with the pole assembly 110. The support cylinder 160 is provided with a male thread on an outer side thereof, the pole assembly 110 is provided with a female thread that matches the male thread. A portion of the support cylinder 160 is inserted into the pole assembly 110 and is in a threaded connection with the pole assembly 110, and another portion of the support cylinder 160 extends out of the pole assembly 110. The support cylinder 160 can be easily removed by unscrewing the portion of the support cylinder 160 extending out of the pole assembly 110. The support cylinder 160 is provided with a coupling hole 161. The guide post 133 is movably inserted into the coupling hole 161. The elastic member 150 is sleeved on the guide post 133, and two ends of the elastic member 150 are located between the coupling hole 161 and the bottom wall of the rotating hole 132, and respectively abuts against the support cylinder 160 and the bottom wall of the rotating hole 132. The deflection of the elastic member 150 during compression or reset, which affects the insertion fit between the locking portion 131 and the engaging portion 141, can be prevented by the guide post 133.
[0075] Still referring to FIGS. 8 and 9, in an embodiment, the support cylinder 160 is provided with a stop block 170. The stop block 170 is detachably connected to the guide post 133. The stop block 170 is adapted to be stopped by a bottom wall of an inner cavity of the support cylinder 160 to limit at least a portion of the guide post 133 in the inner cavity of the support cylinder 160. In this way, it is possible to achieve the movable connection between the first mounting member 130 and the pole assembly 110, and avoid the first mounting member 130 from being separated from the pole assembly 110.
[0076] Optionally, in some other illustrated embodiments, one of the locking portion 131 and the engaging portion 141 is a female thread, and another of the locking portion 131 and the engaging portion 141 is a male thread. In other words, one of the first mounting member 130 and the second mounting member 140 has a female thread structure, and another of the first mounting member 130 and the second mounting member 140 has a male thread structure. The second mounting member 140 is detachably connected to the first mounting member 130 through a threaded connection. Specifically, an end of the first mounting member 130 is provided with the rotation hole 132, and the inner wall of the rotation hole 132 is provided with a female thread. The second mounting member 140 includes the locking sleeve 142 and the connecting base 143. The outer wall of the locking sleeve 142 is provided with a male thread. The locking sleeve 142 can extend into the rotation hole 132 to be threadedly connected to the first mounting member 130.
[0077] An example in which the locking portion 131 is the limiting protrusion 131a and the engaging portion 141 is the limiting groove 141a is given below, to briefly illustrate a process or principle of folding and unfolding the decorative tree 1000 in conjunction with FIGS. 3 and 4 and FIGS. 8 to 11.
[0078] As shown in FIG. 3, when the decorative tree 1000 is in the unfolded state, the pole assembly 110 is in the use state, and the movable support tube assembly 112 is inserted into the fixed support tube assembly 111. In this case, the second mounting member 140 is in locking fit with the locking portion 131 of the first mounting member 130 through the engaging portion 141, to keep the second mounting member 140 at the top end of the pole assembly 110 stably. This allows the decorative mesh 30 (e.g., the light mesh) to be maintained in the expanded state, allowing the decorative tree 1000 to provide a good decorative effect.
[0079] When it is required to fold the decorative tree 1000, the first mounting member 130 and the second mounting member 140 are hand-held to be pressed respectively, so that the limiting protrusion 131a moves out of the limiting space 1414. In this embodiment, since the limiting groove 141a extends from the upper left to the lower right in FIG. 11, the first mounting member 130 and the second mounting member 140 can be released at the same time after the limiting protrusion 131a moves out of the limiting space 1414. The first mounting member 130 rotates in a counterclockwise direction under the resetting force of the elastic member 150, thereby allowing the limiting protrusion 131a to automatically move from the locking end 1412 to the starting end 1411. When the limiting protrusion 131a moves to the starting end 1411, the limiting groove 141a is separated from the limiting protrusion 131a, since the second mounting member 140 automatically moves downward in the length direction of the pole assembly 110 under gravity. During the movement of the second mounting member 140 from the top end to the bottom end of the pole assembly 110, the decorative mesh 30 gradually loosens and collapses in a height direction of the decorative tree 1000. As such, a width or a radial dimension of a portion of the decorative tree 1000 can be reduced. After the second mounting member 140 moves to be completely separated from the movable support assembly 112, that is, after the second mounting assembly 140 moves to the fixed support assembly 111, the movable support tube assembly 112 inserted into the fixed support tube assembly 111 is pulled upward to separate the movable support tube assembly 112 from the fixed support tube assembly 111, so that the height of the decorative tree 1000 can be reduced, thereby facilitating transferring and storing the decorative tree 1000. In addition, after the movable support tube assembly 112 is removed, the movable support tube assembly 112 may be further disassembled into two support tubes 1121 of short length. In order to facilitate storage of the decorative mesh 30, the decorative mesh 30 may also be removed separately.
[0080] When the decorative tree 1000 is required to be used for decoration, the two support tubes 1121 are first assembled into the movable support tube assembly 112, and then the whole movable support tube assembly 112 is inserted into the fixed support tube assembly 111; and the second mounting member 140 is pulled upward to move toward the top end of the pole assembly 110, during which the decorative mesh 30 (e.g., the light mesh) is gradually expanded. After the second mounting member 140 is moved to the top end of the pole assembly 110, the second mounting member 140 is held and the first mounting member 130 is adjusted, so that the limiting protrusion 131a of the first mounting member 130 is aligned to the starting end 1411 of the limiting groove 141a of the second mounting member 140. Then, the first mounting member 130 is pressed and rotated in a clockwise direction, so that the limiting protrusion 131a on the inner side of the first mounting member 130 enters the limiting groove 141a from the starting end 1411 and passes over the engaging protrusion 1413 to reach the locking end 1412. Finally, the first mounting member 130 and the second mounting member 140 are released, the first mounting member 130 has a tendency to move upward under the elastic force of the elastic member 150, and the second mounting member 140 has a tendency to move downward under gravity. As such, the limiting protrusion 131a abuts against the first sidewall 1419a of the limiting groove 141a. Meanwhile, the engaging protrusion 1413 can limit the movement of the limiting protrusion 131a along the first sidewall 1419a of the limiting groove 141a in a direction away from the locking end 1412, so that the limiting protrusion 131a is limited in the limiting space 1414, thereby enabling the second mounting member 140 to be stably fixed at the top end of the pole assembly 110 and the decorative mesh 30 to be maintained in the expanded state.
[0081] Referring to FIGS. 1 to 3, in an embodiment, the tree stand 10 further includes a support base 180. The support base 180 is fixed on the pole assembly 110. The support arm 120 is connected to the pole assembly 110 through the support base 180. Specifically, the support arm 120 is in hinged connection with the support base 180 and has an unfolded state (see FIGS. 1 and 3) and a folded state (see FIG. 9). In this way, the width or the radial dimension of the decorative tree 1000 can be further reduced by switching the state of the support arm 120. Specifically, as shown in FIGS. 2 and 5, the support base 180 includes a first base body 181, a second base body 182 and a third base body 183. The second base body 182 has a second hinged portion 1821. An end of the support arm 120 is hinged to the second hinged portion 1821, and another end of the support arm 120 is connected to the bottom of the decorative mesh 30. The second base body 182 is disposed between the first base body 181 and the third base body 183. The first base body 181 and the third base body 183 are connected through a connector such as a screw, a bolt, or the like. Optionally, in other embodiments (not shown), the second hinged portion 1821 may be further provided with a torsional spring. The torsional spring abuts against the support arm 120 and the second hinged portion 1821, to bias the support arm 120 to switch from the unfolded state to the folded state.
[0082] In an embodiment, the tree stand 10 is provided with a plurality of (e.g., 5, 8, or 12, etc.) support arms 120. The plurality of support arms 120 are connected to the support base 180 at equal spacing along the circumference of the support base 180. An end of each of the support arms 120 away from the support base 180 is connected to the bottom of each of the cords 302 of the decorative mesh 30 (e.g., the light mesh). In this way, the decorative mesh 30 can be evenly spread radially when the support arms 120 are in the unfolded state, so that the decorative mesh 30 is expanded to form a shape of a cone or a bell, thereby playing a good decorative effect.
[0083] Referring to FIGS. 3 and 10, in an embodiment, the tree stand 10 further includes a movable base 190, so as to enable the support arms 120 to be quickly switched between the unfolded state and the folded state. The movable base 190 is movably disposed on the pole assembly 110 and operably connected to the support arms 120 to enable the support arms 120 to be switched between the unfolded state and the folded state. The movable base 190 can be moved between an unfolded position that places the support arms 120 in the unfolded state and a folded position that places the support arms 120 in the folded state. In this way, the states of the support arms 120 can be controlled by manipulating the movable base 190. It should be noted that the wording the movable base 190 is movably disposed on the pole assembly 110 means that the movable base 190 is movable in the axial direction or the length direction of the pole assembly 110. Specifically, as shown in FIGS. 4 and 10, in this embodiment, the movable base 190 is operably connected to the support arms 120 through a link member 210. More specifically, as shown in FIGS. 4 and 12, the movable base 190 has a connecting body 191. The connecting body 191 includes a first hinged portion 1911. An end of the link member 210 is hinged to the first hinged portion 1911, and another end of the link member 210 is hinged to the support arms 120 to drive the support arms 120 to switch between the unfolded state and the folded state. Specifically, the first hinged portion 1911 is formed by bending a connecting plate and includes a first slot 1912. An insertion rod (not shown) is inserted through the first slot 1912, and the link member 210 is hooked on the insertion rod and is rotatable relative to the insertion rod.
[0084] Referring to FIGS. 1, 3 and 4, the support base 180 is fixedly sleeved on the fixed support tube assembly 111 of the pole assembly 110. The plurality of support arms 120 are connected to the support base 180 at equal spacing along the circumference of the support base 180.
[0085] Accordingly, a plurality of link members 210 are provided. The number of the link members 210 is equal to the number of the support arms 120. More specifically, the connecting body 191 is provided with a plurality of first hinged portions 1911 disposed at equal spacing in the circumferential direction of the pole assembly 110. The number of first hinged portions 1911 is equal to the number of link members 210. Each of the link members 210 is hinged between the corresponding support arm 120 and the corresponding first hinged portion 1911.
[0086] Referring to FIGS. 13 to 16, in an embodiment, the tree stand 10 further includes a first locking mechanism 220. The first locking mechanism 220 is disposed on the movable base 190 and has a locked state and an unlocked state. When the first locking mechanism 220 is in the locked state, the movable base 190 is limited from moving relative to the pole assembly 110, thereby limiting the support arms 120 from switching between the folded (see FIG. 10) and the unfolded state (see FIG. 3). When the first locking mechanism 220 is in the unlocked state, the movable base 190 is allowed to move relative to the pole assembly 110, thereby allowing the support arms 120 to switch between the unfolded state and the folded state. It should be noted that the wording the movable base 190 is limited from moving relative to the pole assembly 110, thereby limiting the support arms 120 from switching between the folded (see FIG. 10) and the unfolded state (see FIG. 3) is to be understood as follows: when the movable base 190 is locked in the unfolded position, the support arms are locked in the unfolded state; when the movable base 190 is locked in the folded position, the support arms 120 are locked in the folded state; and when the movable base 190 is locked in a predetermined position between the unfolded position and the folded position, the support arms 120 is locked in a predetermined half-folded state between the unfolded state and the folded state.
[0087] As shown in FIGS. 3, 4, and 10, in an embodiment, the pole assembly 110 is provided with at least one locking recess 101. The at least one locking recess 101 is a hole or a groove. As shown in FIGS. 13, 15 and 16, the first locking mechanism 220 includes a locking member 221. The locking member 221 is disposed on the movable base 190 and is capable of moving in a first direction F1, so that the locking member 221 is movable between a locked position and an unlocked position, i.e., the first locking mechanism 220 is capable of switching between the locked state and the unlocked state. When the locking member 221 is in the locked position (i.e., the first locking mechanism 220 is in the locked state), the locking member 221 is adapted to extend into one of the at least one locking recess 101 to limit movement of the movable base 190 relative to the pole assembly 110, and when the locking member 221 is in the unlocked position (i.e., the first locking mechanism 220 is in the unlocked state), the locking member 221 is adapted to withdraw from the respective one of the locking recesses 101 to allow the movable base 190 to move relative to the pole assembly 110.
[0088] Referring to FIGS. 4 and 10, the at least one locking recess 101 includes a first locking recess 101a. The first locking recess 101a is a hole and disposed on the fixed support tube assembly 111. More specifically, when the movable base 190 is in the unfolded position and the locking member 221 is in the locked position, the locking member 221 extends into the first locking recess 101a, so that the movable base 190 is locked in the unfolded position, thereby locking the support arms 120 in the unfolded state. When the locking member 221 is in the unlocked position, the locking member 221 withdraws from the first locking recess 101a, so that the movable base 190 is movable between the unfolded position and the folded position to allow the support arms 120 to switch between the unfolded state and the folded state. The first direction F1 is parallel to the radial direction of the pole assembly 110.
[0089] Referring to FIGS. 3 and 4, the at least one locking recess 101 includes a second locking recess 101b disposed on the pole assembly 110. The second locking recess 101b is a hole. Specifically, in this embodiment, two locking recesses 101 are provided. The two locking recesses 101 are respectively the first locking recess 101a and the second locking recess 101b. More specifically, the second locking recess 101b is arranged above the first locking recess 101a in the axial direction of the pole assembly 110. When the locking member 221 withdraws from the first locking recess 101a, the support arms 120 can be driven to switch gradually from the unfolded state to the folded state by moving the movable base 190 upward. When the movable base 190 is moved to the vicinity of the second locking recess 101b, i.e., when the movable base 190 is substantially in the folded position, the support arms 120 are substantially in the folded state. When the locking member 221 is aligned to the second locking recess 101b, the locking member 221 is inserted into the second locking recess 101b, so that the movable base 190 is limited from moving relative to the pole assembly 110, fixing the movable base 190 near the second locking recess 101b, thereby allowing the support arms 120 to be maintained in the folded state.
[0090] In some other illustrated embodiments, the at least one locking recess 101 further includes other locking recesses provided between the first locking recess 101a and the second locking recess 101b. When the movable base 190 is moved to one of the other locking recesses 101, the locking member 221 can extend into the one of the other locking recesses 101 to lock the support arms 120 in the corresponding half-folded state. In this way, spreading width of the support arms 120 in the radial direction can be adjusted to adapt to decorative mesh 30 of different sizes.
[0091] Referring to FIGS. 13 to 16, in an embodiment, the movable base 190 includes a through channel 192. The movable base 190 is sleeved on the pole assembly 110 through the through channel 192 (see FIG. 10). The movable base 190 further includes a receiving cavity 193 and a through hole 194. The through hole 194 is in communication with the receiving cavity 193 and the through channel 192. The locking member 221 is at least partially movably disposed in the receiving cavity 193. In other embodiments, the movable base 190 does not need to be provided with the receiving cavity 193 and the through hole 194, and the locking member 221 may be movably disposed on an upper end surface or a lower end surface of the movable base 190 directly.
[0092] Specifically, as shown in FIGS. 13 and 15, the first locking mechanism 220 further includes a first reset member 222. The first reset member 222 abuts against the locking member 221 to bias the locking member 221 to move from the unlocked position to the locked position. The first reset member 222 is, for example, a spring, an elastic sheet, or the like. Specifically, the first reset member 222 is a spring provided in the receiving cavity 193. Two ends of the first reset member 222 abut against an inner wall of the receiving cavity 193 and the locking member 221 respectively to bias the locking member 221 to move in a direction of extending out of the through hole 194.
[0093] Specifically, as shown in FIGS. 12, 15 and 16, the movable base 190 includes an upper shell 195 and a lower shell 196 which are connected to each other. The upper shell 195 and the lower shell 196 is detachably connected to each other, for example, in a threaded connection by a connector, such as a screw or the like, or engaged with each other by a connector, such as a snapper or the like. The through channel 192 includes a first channel 1921 and a second channel 1922. The upper shell 195 includes an inner ring portion 1951 provided with the first channel 1921 and an outer peripheral portion 1952 surrounded the inner ring portion 1951. The outer peripheral portion 1952 is connected to the inner ring portion 1951. The receiving cavity 193 is formed between the outer peripheral portion 1952 and the inner ring portion 1951. The inner ring portion 1951 is provided with the through hole 194. In this embodiment, the inner ring portion 1951 may be regarded as an annular inner ring baffle, and the outer peripheral portion 1952 may be regarded as an annular outer ring baffle. The inner ring portion 1951 and the outer peripheral portion 1952 are connected by a plate 1953. The annular inner ring baffle, the plate 1953 and the annular outer ring baffle together define the receiving cavity 193 with an opening at an end. The upper shell 195 may be sleeved on the pole assembly 110 through the first channel 1921. Further, the lower shell 196 includes the second channel 1922. The lower shell 196 is sleeved on the pole assembly 110 through the second channel 1922.
[0094] Optionally, the connecting body 191 is fixedly connected to a side of the lower shell 196 of the movable base 190 facing away from the upper shell 195. Alternatively, the connecting body 191 is integrally formed to the side of the lower shell 196 facing away from the upper shell 195. Alternatively, the connecting body 191 is detachably connected to the side of the lower shell 196 facing away from the upper shell 195. Specifically, in this embodiment, the connecting body 191 is detachably connected to the side of the lower shell 196 facing away from the upper shell 195 by a screw or a bolt or the like. More specifically, referring to FIG. 16, in this embodiment, the tree stand 10 further includes a resisting member 198. The connecting body 191 is fixed to the lower shell 196 through the resisting member 198 and a screw. The connecting body 191 has a cylindrical structure. The plurality of the first hinged portions 1911 are disposed on the outer peripheral wall of the connecting body 191 at equal spacing along the circumference of the connecting body 191. A mounting gap 1913 is formed between the two adjacent first hinged portions 1911 (see FIG. 16). The resisting member 198 includes a circular sleeve 1981, and a connecting foot 1982 provided with a connecting hole (not shown). Specifically, a plurality of connecting feet 1982 are provided. The plurality of the connecting feet 1982 are disposed on an outer wall of the circular sleeve 1981 at equal spacing. The number of first hinged portions 1911 is an integer multiple of (e.g., double, triple, triple, etc.) the number of connecting feet 1982. More specifically, as shown in FIG. 14, eight first hinged portions 1911 are provided, four connecting feet 1982 are provided. The four connecting feet 1982 are disposed on the outer wall of the circular sleeve 1981 at equal spacing. When being connected, the circular sleeve 1981 is configured to hold the connecting body 191 against the lower shell 196, each of the connecting feet 1982 is engaged into the corresponding one of the mounting gaps 1913, and then, the screws extend through the connecting holes respectively to be connected to the lower shell 196 to complete a connection.
[0095] In an embodiment, a side of the inner ring portion 1951 facing the first channel 1921 is provided with a first avoidance groove 19511 (see FIGS. 16 and 17). The first avoidance groove 19511 extends in a length direction of the first channel 1921. Specifically, the side of the inner ring portion 1951 facing the first channel 1921 is provided with a plurality of first avoidance grooves 19511. The first avoidance grooves 19511 are spaced apart in a circumferential direction of the first channel 1921. In this way, the contact area between the movable base 190 and the pole assembly 110 can be reduced, and when the pole assembly 110 is locally deformed, for example, when a bump or the like is formed on the pole assembly 110, the first avoidance grooves 19511 can pass over through the bump, so that the movement of the movable base 190 will not be affected.
[0096] Referring to FIGS. 16 and 17, in an embodiment, a side of the lower shell 196 facing the upper shell 195 is provided with a limiting portion 197. Specifically, the limiting portion 197 includes two limiting guides 1971 disposed opposite to each other, and a first limiting slot 1972 is formed between the two limiting guides 1971. The first limiting slot 1972 extends in a first direction F1. The first reset member 222 and locking member 221 are movably disposed and limited in the first limiting slot 1972. Movement paths of the first reset member 222 and the locking member 221 are ensured by the first limiting slot 1972. In addition, a side of the outer peripheral portion 1952 facing the receiving cavity 193 is provided with a limiting post 19521. The limiting post 19521 faces the through hole 194. The first reset member 222 is sleeved on the limiting post 19521 to further prevent the first reset member 222 from being deflected.
[0097] Referring to FIGS. 10, 12 and 13, in an embodiment, the tree stand 10 further includes an unlocking mechanism 230. The unlocking mechanism 230 is configured to drive the locking member 221 to move from the locked position to the unlocked position, that is, the unlocking mechanism 230 is configured to drive the first locking mechanism 220 to switch from the locked state to the unlocked state.
[0098] Specifically, as shown in FIGS. 13 and 16, the unlocking mechanism 230 includes an unlocking member 231. The unlocking member 231 is operably connected to the locking member 221 to drive the locking member 221 to move from the locked position to the unlocked position. Specifically, the unlocking member 231 has a first position and a second position. The locking member 221 is in the locked position when the unlocking member 231 is in the first position, and the locking member 221 is in the unlocked position when the unlocking member 231 is in the second position.
[0099] Still referring to FIGS. 13 and 16, in an embodiment, the unlocking member 231 is disposed on the movable base 190. The unlocking member 231 is capable of moving with the movable base 190 in the axial direction of the pole assembly 110, and moving in the second direction F2 relative to the movable base 190 to enable the unlocking member 231 to switch between the first position and the second position. When the unlocking member 231 moves from the first position to the second position, the unlocking member 231 drives the locking member 221 to move from the locked position to the unlocked position in the first direction F1. The second direction F2 is parallel to the radial direction of the pole assembly 110, but not parallel to the first direction F1 (i.e., at an angle to the first direction F1). Specifically, the second direction F2 is substantially perpendicular to the first direction F1.
[0100] Still referring to FIGS. 13 and 16, the unlocking mechanism 230 further includes a guide member 232. The guide member 232 is disposed within the receiving cavity 193, and provided with a limiting hole 2321 corresponding to the through hole 194. The locking member 221 is movably inserted into the limiting hole 2321 and at least partially limited in the limiting hole 2321. Referring to FIG. 17, the guide member 232 is provided with a second limiting slot 2324. The second limiting slot 2324 faces and is in communication with the first limiting slot 1972. The limit hole 2321 extends through a bottom wall of the second limiting slot 2324. The locking member 221 is provided with a limiting boss 223. The locking member 221 is inserted into the limiting hole 2321, and the limiting boss 223 is capable of abutting against an opening edge of the limiting hole 2321 (i.e., the limiting boss 223 is capable of abutting against the bottom wall of the second limiting slot 2324) to limit at least a part of the locking member 221 in the limiting hole 2321. In this way, it can be avoided that the whole locking member 221 is separated from the limit hole 2321 and the through hole 194 when an end of the locking member 221 away from the first reset member 222 extends through the limiting hole 2321 and the through hole 194.
[0101] As shown in FIGS. 13 and 16, the outer peripheral portion 1952 is provided with an operation hole 19522 in communication with the receiving cavity 193. The unlocking member 231 extends through the operation hole 19522, and is movably disposed in the receiving cavity 193. When the unlocking member 231 moves from the first position to the second position in the second direction F2, the unlocking member 231 pushes against the guide member 232 to move in the first direction F1 and drives the locking member 221 to move from the locked position to the unlocked position.
[0102] Referring to FIG. 16, in an embodiment, the guide member 232 is provided with a sliding guide groove 2322 to avoid deflection of the guide member 232 during movement. The sliding guide groove 2322 extends in the first direction F1, and is configured to slidably cooperate with the limiting guides 1971.
[0103] As shown in FIGS. 13 and 16, in an embodiment, the unlocking member 231 includes an operation button 2311 and a push arm 2312 which are connected to each other. The unlocking member 231 is integrally formed. The push arm 2312 is movably disposed in the receiving cavity 193. The operation button 2311 is inserted into the operation hole 19522. In this embodiment, at least a portion of the operation button 2311 extends through the operation hole 19522 and extends out of the receiving cavity 193, i.e., the operation button 2311 protrudes from an outer side surface of the outer peripheral portion 1952. As such, it is convenient for the user to operate the operation button 2311. In some alternative embodiments, the operation button 2311 is embedded in the operation hole 19522, and an outer side surface of the operation button 2311 may be flushed with the outer side surface of the outer peripheral portion 1952, or recessed relative to the outer side surface of the outer peripheral portion 1952, and the user may operate the operation button 2311 through the operation hole 19522. When the operation button 2311 is moved inward in the second direction F2, i.e., when the operation button 2311 is moved toward the inner ring portion 1951 in the second direction F2, the push arm 2312 is driven to move in the second direction F2, and the guide member 232 is pushed to move outward in the first direction F1 by the push arm 2312.
[0104] Specifically, as shown in FIGS. 13 and 17, an end of the push arm 2312 away from the operation button 2311 includes a driving bevel 2313. The driving bevel 2313 is inclined relative to the second direction F2. Optionally, when the unlocking member 231 is in the first position and the locking member 221 is in the locked position, the guide member 232 abuts against a bottom end of the driving bevel 2313. In other embodiments, the guide member 232 may be not in contact with the driving bevel 2313 when the unlocking member 231 is in the first position and the locking member 221 is in the locked position. Referring to FIG. 17, the guide member 232 includes a guide portion 2323. The guide portion 2323 is curved, and configured to abut against the drive bevel 2313, so that the drive bevel 2313 can be positioned between the guide member 232 and the inner ring portion 1951. In other words, when the push arm 2312 is moved from the first position to the second position, the driving bevel 2313 can abut against a side of the guide member 232 facing the through channel 192 through the guide portion 2323.
[0105] Returning to refer to FIGS. 13 and 16, in an embodiment, the unlocking mechanism 230 further includes a second reset member 233. Two ends of the second reset member 233 abut against the operation button 2311 and the inner ring portion 1951 respectively to bias the unlocking member 231 to move from the second position to the first position.
[0106] Specifically, in this embodiment, as shown in FIGS. 13 and 16, two first locking mechanisms 220 and two guide members 232 are provided. The inner ring portion 1951 is provided with two through holes 194. The two locking members 221 are disposed corresponding to the two guide members 232, and capable of extending out of the corresponding through holes 194. More specifically, the unlocking member 231 includes two push arms 2312. The two push arms 2312 are movably disposed in the receiving cavity 193 and are connected to the operation button 2311. More specifically, in a circumferential direction of the inner ring portion 1951, the unlocking member 231 is located between the two first locking mechanisms 220, i.e., one of the push arms 2312 is connected to one of the guide members 232 and another of the push arms 2312 is connected to another of the guide members 232. In this way, when the operation button 2311 is moved in the second direction F2, the two push arms 2312 are simultaneously driven to move in the second direction F2 and abut against the guide members 232 respectively, and thus the two locking members 221 can be controlled at the same time. In other embodiments, the unlocking member 231 may include one operation button 2311 and one push arm 2312. The number of the unlocking member 231 is set corresponding to the number of the locking members 221, and each of the unlocking members 231 acts on the corresponding one of the locking members 221.
[0107] Still referring to FIGS. 13 and 16, in this embodiment, two unlocking mechanisms 230 are provided. The two unlocking mechanisms 230 and the two first locking mechanisms 220 are disposed alternately in the movable base 190 in the circumferential direction of the inner ring portion 1951. Specifically, the two unlocking mechanisms 230 are provided opposite to each other, and the two first locking mechanisms 220 are provided opposite to each other. In this way, during unlocking, each locking member 221 can be simultaneously pushed by the driving bevels 2313 on the push arms 2312 on its left and right sides.
[0108] Referring to FIGS. 1, 3 and 4, in an embodiment, the tree stand 10 further includes a bottom support mechanism 240. The bottom support mechanism 240 includes a support body 241 and a support foot 242. An insertion hole 2411 is provided at an end of the support body 241 and configured to receive the bottom end of the pole assembly 110. A plurality of support feet 242 are provided. The plurality of support feet 242 are spaced apart in a circumferential direction of the support body 241. Specifically, three or more support feet 242 are provided. Thus, the support body 241 can stably support the pole assembly 110.
[0109] A specific process of folding the decorative tree 1000 is illustrated below in conjunction with the drawings.
[0110] Referring to FIGS. 4 and 10, when the tree stand 10 is folded, the pole assembly 110 is separated from the bottom support mechanism 240, the fixed support tube assembly 111 of the pole assembly 110 is separated from the movable support tube assembly 112, and the support tubes 1121 of the movable support tube assembly 112 are also separated from each other (not shown). In this case, the second mounting member 140 is located on the fixed support tube assembly 111, the movable base 190 is located at the second locking recess 101b (i.e., in the folded position), the first locking mechanism 220 is in the locked state, i.e., the locking member 221 is inserted into the second locking recess 101b. The support arms 120 are in the folded state, and the decorative mesh 30 is collapsed and stacked together (not shown).
[0111] Referring to FIGS. 1, 4, 9, 10, 13 and 17, when the decorative tree 1000 is required to be used to achieve a decorative role, the fixed support tube assembly 111 is inserted into the support body 241 of the bottom support mechanism 240, and subsequently, the two support tubes 1121 are assembled into the movable support tube assembly 112. Then, the movable support tube assembly 112 is inserted onto the fixed support tube assembly 111. Then, the second mounting member 140 is pulled upward to move toward the top end of the pole assembly 110 in the length direction of the pole assembly 110, and the first mounting member 130 is pressed and rotated, so that the locking portion 131 of the first mounting member 130 is locked with the engaging portion 141 of the second mounting member 140. When the second mounting member 140 moves upward, the second mounting member 140 drives the top of the decorative mesh 30 to move, so that the decorative mesh 30 can be expanded in the length direction of the pole assembly 110. After the second mounting member 140 and the first mounting member 130 are locked to each other, the operation button 2311 is pressed, the operation button 2311 pushes the push arms 2312 to move, the driving bevels 2313 cooperate with the guiding portions 2323, so that the locking member 221 withdraws from the second locking recess 101b and retracts into the through hole 194 thereby allowing the movable base 190 to slide relative to the pole assembly 110. Subsequently, the movable base 190 is pushed downward in the length direction of the pole assembly 110. The movable base 190 moves to drive the link members 210 to move, and since each of the link members 210 is hinged between the corresponding support arm 120 and the connecting body 191 (which may be regarded as a part of the movable base 190) of the movable base 190, each of the link members 210 pushes the corresponding support arm 120 to unfold gradually (see FIG. 1), thereby enabling the decorative mesh 30 to be expanded in the radial direction. Referring to FIGS. 10 and 15, when the movable base 190 moves to the first locking recess 101a (i.e., the unfolded position), the locking member 221 does not abut against the pole assembly 110, and under the action of the first reset member 222, the locking member 221 extends out of the through hole 194 and extends into the first locking recess 101a, so that the movable base 190 is locked in the unfolded position, and thus allowing the support arms 120 to be maintained in the unfolded state (see FIG. 1). In other embodiments, the user may move the movable base 190 first to unfold the support arms 120, and then pull the second mounting member 140 to move upward, and then perform the locking operation.
[0112] When the decorative tree 1000 needs to be stored or transferred, referring to FIGS. 10, 13 and 17, the user may press the operation button 2311 first, the operation button 2311 pushes the push arm 2312 to move, and the driving bevels 2313 cooperate with the guiding portions 2323, so that the locking member 221 withdraws from the first locking recess 101a and retracts into the through hole 194, thereby allowing the moving base 190 to slide relative to the pole assembly 110. Subsequently, the movable base 190 is pulled upward, and the corresponding support arm 120 is driven by the link member to switch automatically from the unfolded state to the folded state, so as to reduce the volume of the decorative tree 1000. When the movable base 190 moves to the second locking recess 101b (i.e., the folded position), the locking member 222 does not abut against the pole assembly 110, and extends into the second locking recess 101b under the action of the first reset member 222, so that the movable base 190 is locked in the folded position, and thus allowing the support arms 120 to maintain in the folded state. Subsequently, the second mounting member 140 and the first mounting member 130 are unlocked, and the second mounting member 140 is moved downward along the pole assembly 110 to the fixed support tube assembly 111, so that the decorative mesh 30 is collapsed and stacked together, to reduce the volume of the decorative mesh 30. Finally, the movable support tube assembly 112 is removed from the fixed support tube assembly 111 and disassembled, and then the fixed support tube assembly 111 is removed from the bottom support mechanism 240 to finish the folding of the decorative tree 1000. In other embodiments, the user may also unlock the second mounting member 140 and the first mounting member 130, and then move the movable base 190 to realize the folding of the decorative tree 1000.
[0113] Embodiments of the present application further provide a decorative tree 1000, which includes a decorative mesh 30 and the tree stand 10 as described in any of the above embodiments. The top of the decorative mesh 30 is connected to the second mounting member 140, and the bottom of the decorative mesh 30 is connected to the support arms 120.
[0114] The above tree stand 10 and the above decorative tree 1000 have at least the following advantages.
[0115] The tree stand 10 according to the present application allows the support arms 120 to have the unfolded state and the folded state by hinging the support arms 120 to the support base 180, so that the overall volume (radial dimension) of the tree stand 10 and the decorative tree 1000 can be changed, and, the lateral occupation space can be reduced. In this way, during transferring and storing the decorative tree 1000, the support arms 120 can be maintained in the folded state to reduce the overall volume of the decorative tree 1000, thereby saving space for storage and transportation. Since the support arms 120 are located at the bottom end of the pole assembly 110 and connected to the bottom of the decorative mesh 30, and the second mounting member 140 is movably disposed on the pole assembly 110 and connected to the top of the decorative mesh 30, the state of the decorative mesh 30 can be changed by changing the position of the second mounting member 140, allowing the decorative mesh 30 to be switched between the expanded state and the collapsed state. The first mounting member 130 is mounted at the top end of the pole assembly 110 and has the locking portion 131, and the second mounting member 140 has the engaging portion 141 capable of being locked with the locking portion 131. Therefore, when the second mounting member 140 is moved to the top end of the pole assembly 110, the user can operate the first mounting member 130 to interlock the locking portion 131 with the engaging portion 141, so that the second mounting member 140 is fixed and the decorative mesh 30 is maintained in the unfolded state, to plays a good decorative role. In addition, the user can operate the first mounting member 130 to unlock the locking portion 131 with the engaging portion 141, thereby separating the second mounting member 140 from the first mounting member 130. When the second mounting member 140 is separated from the first mounting member 130, the second mounting member 140 automatically moves to the bottom end of the pole assembly 110 under gravity, to switch the decorative mesh 30 to the collapsed state, and thus, the volume of the decorative tree 1000 can be reduced. In other words, when it is required to unfold the decorative tree 1000 to achieve the decorative role, the user may quickly pull the second mounting member 140 to move to the top end, and then interlock the locking portion 131 with the engaging portion 141 by operating the first mounting member 130; and when it is required to reduce the volume of the decorative tree 1000 for storage or transportation, the user may unlock the locking portion 131 from the engaging portion 141 by operating the first mounting member 130. As such, the above tree stand 10 is beneficial to simplify steps of unfolding and folding the decorative tree 1000 and improve efficiency of unfolding and folding the decorative tree. Moreover, the movable support tube assembly 112 is detachable from the fixed support tube assembly 111, so that the overall height of the decorative tree 1000 can be reduced, i.e., the longitudinal occupation space can be reduced, saving space for storage and transportation.
[0116] The technical features in the above embodiments may be randomly combined. For concise description, not all possible combinations of the technical features in the above embodiments are described. However, all the combinations of the technical features are to be considered as falling within the scope described in this specification provided that they do not conflict with each other.
[0117] The above embodiments only describe several implementations of the present application, and their description is specific and detailed, but cannot therefore be understood as a limitation on the patent scope of the application. It should be noted that those of ordinary skill in the art may further make variants and improvements without departing from the conception of the present application, and these all fall within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
