[0028] The present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] As shown in FIGS. 1 to 6, the present application discloses an angle-adjustable table, which can serve as a study desk or work desk. The angle-adjustable table includes a table top 1, a table base 3, a table leg 2, and a rotating shaft 4 connected to the table leg 2. A lower end of the table leg 2 is connected to the table base 3. Specifically, there is only one table leg 2, connected to one end of the table base 3. The rotating shaft 4 is connected to an upper end of the table leg 2. The rotating shaft 4 may be a hollow cylindrical tube extending horizontally from the table leg 2. The table top 1 is rotatably connected to the rotating shaft 4 and can rotate around the rotating shaft 4. The table top 1 can be locked relative to the rotating shaft 4 at any tilting angle. Therefore, the table top 1 of the angle-adjustable table can be flipped to at least a horizontal position, a tilted position, and a vertical position. In the horizontal position, it can be used as a study desk; in the tilted position, it can be used as a reading desk; and in the vertical position, it can be stored to occupy less indoor space.

[0030] In some embodiments, as shown in FIG. 4, the table leg 2 includes an outer tube and an inner tube slidably fitted in the outer tube. A gas spring 7 is provided in the inner tube. An upper end of the gas spring 7 is connected to the inner tube, and a lower end of the gas spring 7 is connected to a bottom of the outer tube. A control valve of the gas spring 7 is set at the upper end of the gas spring 7, and a rotary switch 700 is rotatably connected to an upper end of the inner tube. The rotary switch 700 is configured to control the control valve of the gas spring. When the rotary switch 700 drives the control valve to open, the gas spring 7 extends and the table leg 2 rises, thereby realizing the height adjustment of the table top 1.

[0031] In some embodiments, the table leg 2 may be an electrically lifting table leg, where a driving motor and a linear driving mechanism are provided in the table leg 2, and the driving motor is configured to drive a transmission nut of the linear driving mechanism to move to adjust the height of the table leg.

[0032] In some embodiments, the table leg 2 may be an ordinary table leg whose height is nonadjustable.

[0033] Furthermore, in order to lock the position of the table top 1 relative to the rotating shaft 4 after angle adjustment, as shown in FIGS. 1, 2, 3 and 4, the angle-adjustable table further includes a locking mechanism 5, which includes a rotating base 500 and a fixed base 501. The rotating base 500 is mounted on the table top 1, and the fixed base 501 is mounted on the rotating shaft 4. Specifically, the rotating base 500 is mounted on a bottom surface of the table top 1, and the fixed base 501 is sleeved over the rotating shaft 4. The rotating base 500 is rotatably connected to the rotating shaft 4 and can slide along an axial direction of the rotating shaft 4, so as to rotate the table top 1 around the rotating shaft 4 to adjust an angle of the table top 1 and to allow the table top 1 to move along the rotating shaft 4. Specifically, a center hole is provided on the rotating base 500, which is sleeved over the rotating shaft 4 and can rotate relative to the rotating shaft 4 and can slide axially along the rotating shaft 4 within a certain range, so that the table top 1 and the rotating base 500 can rotate relative to the rotating shaft 4 as a whole and can slide axially along the rotating shaft 4. The rotating base 500 is provided with a first locking structure 513 , and the fixed base 501 is provided with a second locking structure 514 configured to match and lock with the first locking structure 513.

[0034] When the rotating base 500 moves along with the table top 1 in a direction closer to the fixed base 501, the first locking structure 513 can match and engage the second locking structure 514, thereby locking the two. Similarly, when the rotating base 500 moves along with the table top 1 in a direction away from the fixed base 501, the first locking structure 513 can disengage the second locking structure 514, thereby unlocking the two. Therefore, in a locked state, the position and the angle of the table top 1 can be fixed, and in an unlocked state, the position and the angle of the table top 1 can be adjusted.

[0035] As shown in FIG. 4, the fixed base 501 may be fixedly sleeved over the rotating shaft 4 by screws, and the fixed base 501 can limit the sliding of the table top 1 and the rotating base 500 with the rotating base 500 being rotatable relative to the rotating shaft 4 and capable of sliding along the axial direction of the rotating shaft 4. Further, a first guiding hole 401 is provided on the rotating shaft 4, and the first guiding hole 401 is expanded along a circumference of the rotating shaft 4 and along the axial direction of the rotating shaft 4. A first positioning screw 512 is connected to the rotating base 500, and the first positioning screw 512 is loosely arranged in the first guiding hole 401. When the rotating base 500 rotates relative to the rotating shaft 4, the first positioning screw 512 moves along a length direction of the first guiding hole 401, and when the rotating base 500 moves axially along the rotating shaft 4, the first positioning screw 512 moves along a width direction of the first guiding hole 401. The cooperation between the first positioning screw 512 and the first guiding hole 401 limits the rotation and horizontal movement of the rotating base 500 and the table top 1.

[0036] In order to facilitate the angle adjustment and locking of the table top 1, as shown in FIGS. 4, 5 and 6, the locking mechanism 5 further includes a driving handle 502, which is rotatably connected to the table top 1, and the driving handle 502 is connected to the rotating shaft 4 through a connecting rod 506 to drive the table top 1 to move along the axis direction of the rotating shaft 4, so that the locking mechanism 5 is switched to the locked state or the unlocked state. Specifically, the locking mechanism is switched to the locked state when the rotating base 500 moves along the axial direction of the rotating shaft 4 toward the fixed base 501 to engage and lock the first locking structure 513 and the second locking structure 514, and the locking mechanism is switched to the unlocked state when the rotating base 500 moves along the axial direction of the rotating shaft 4 away from the fixed base to disengage and unlock the first locking structure 513 and the second locking structure 514. That is, the connecting rod 506 is connected to the rotating shaft 4, and the connecting rod 506 and the rotating shaft 4 do not move in the axial direction. Since the fixed base 501 is fixedly connected to the rotating shaft 4, the second locking structure 514 on the fixed base 501 is not allowed to move along the axial direction of the rotating shaft 4. When the user drives the driving handle 502 to rotate, the driving handle 502 takes the end of the connecting rod 506 adjacent to the driving handle 502 as a fulcrum, thereby driving the table top 1 to move along the axial direction of the rotating shaft 4, so that the rotating base 500 connected to the table top 1 moves toward or away from the fixed base 501, and further causing the first locking structure 513 on the rotating seat 500 to come into contact with and lock to, or disengage from and unlock from, the second locking structure 514 on the fixed base 501.

[0037] With such arrangements, the angle-adjustable table allows the angle of the table top 1 to be adjustable, and once the angle is adjusted, the table top 1 can be locked in position. The locking mechanism 5 is simple in structure, easy to operate, and very labor-saving. Furthermore, the settings of the first locking structure and the second locking structure not only make the locking of the table top 1 more secure and stable after the adjustment, but also make the assembly operation very convenient. Specifically, simply mounting the rotating base 500 on the bottom of the table top 1 and sleeving it over the rotating shaft 4 to align with the fixed base 501 will be almost enough, which reduces the assembly precision requirements and greatly improves the efficiency of the assembly operation. In addition, the table top 1 can slide on the rotating shaft 4 along with the rotating base 500. Especially in the angle adjustment process of the table top 1, the table top 1 and the rotating base 500 firstly slide to a position away from the fixed base 501 by driving the driving handle 502, and then slide in an opposite direction when locked. In this way, for the angle-adjustable table placed near a wall or against a wall, when adjusting the table top 1, the table top 1 can move away from the wall, which is more convenient to operate and avoids interference from the wall. When locking, the table top 1 can be brought closer to the wall to fill the gap between the table top 1 and the wall, thereby preventing items from falling and making fuller use of the space.

[0038] It is easy to understand that when the driving handle 502 rotates along the circumference of the rotating shaft 4 with the table top 1, the connecting rod 506 also rotates synchronously relative to the rotating shaft 4. Specifically, as shown in FIGS. 4 and 6, a base 505 is mounted on the bottom of the table top 1, and the driving handle 502 is rotatably connected to the base 505 via a rotating pin 503. The driving handle 502 is provided with a connecting portion 504, and the rotating pin 503 is not rotatably connected to the driving handle 502 at the connecting portion 504. A rotating block 509 is rotatably connected to the rotating shaft 4, and the rotating block 509 is limited along the axis direction of the rotating shaft 4. The connecting rod 506 is arranged in the rotating shaft 4, and one end of the connecting rod 506 is connected to the rotating block 509 by a screw, and the other end of the connecting rod 506 is connected to the connecting portion 504.

[0039] As shown in FIGS. 4 and 6 , an inner end ,which is close to the rotating base, of the driving handle 502 may be rectangular or elongated. One side of the inner end of the driving handle 502 is rotatably connected to the base 505 via the rotating pin 503, and an another side of the inner end of the driving handle 502 is provided with a connecting hole, which forms the connecting portion 504. In other words, the connecting hole and the rotating pin 503 are not concentric or their axises are horizontally parallel. A connecting member 511 is disposed in the base 505. One end of the connecting member 511 is rotatably connected to the connecting portion 504, and the other end of the connecting member 511 is rotatably connected to the connecting rod 506. When the driving handle 502 rotates, the connecting portion 504 of the driving handle 502 and the connecting rod 506 form a fulcrum, so that the rotating pin 503 of the driving handle 502 drives the table top 1 to move along the axis direction of the rotating shaft 4.

[0040] Furthermore, the rotating block 509 is disposed within the center hole of the hollow rotating shaft 4 and is rotatable along the circumference of the rotating shaft 4. Specifically, a second guide hole 402, which extends along the circumference of the rotating shaft 4, is disposed at the rotating shaft 4, and a second positioning screw 510 is connected to the rotating block 509. The second positioning screw 510 has a clearance fit within the second guide hole 402. Therefore, on the one hand, the second positioning screw 510 is slidable along a length of the second guide hole 402, on the other hand, the second positioning screw 510 is limited along the axis direction of the rotating shaft 4 by the second guide hole 402. When the table top 1 and the driving handle 502 rotate synchronously, the driving handle 502 drives the rotating block 509 to rotate synchronously via the connecting rod 506.

[0041] In some embodiments, the driving handle 502 may be configured to rotate relative to the connecting rod 506. That is, the rotating block 509 and the connecting rod 506 do not rotate relative to the rotating shaft 4, so that the driving handle 502 rotates along the circumference of the connecting rod 506. For example, the driving handle 502 and the connecting rod 506 may be connected via a universal ball head.

[0042] In order to enable the locking mechanism 5 to respond quickly and achieve rapid locking, the locking mechanism 5 further includes an elastic member 507 configured to enable the first locking structure of the rotating base to have a continuous movement tendency to engage and lock with the second locking structure of the fixed base. Specifically, the elastic member 507 is arranged on the rotating shaft 4. The driving handle 502 can be actuated, which drives the base 505 as well as the table top 1 to move along the axis direction of the rotating shaft 4 to move away from the fixed base 501, resulting in the elastic member 507 being compressed and the first locking structure 513 and the second locking structure 514 being disengaged. With the first locking structure 513 and the second locking structure 514 being disengaged, the angle of the table top 1 can be adjustable. Once the angle adjustment is finished, the driving handle 502 can be released. With the the driving handle 502 released, an elastic force of the compressed elastic member 507 can reset the position of the driving handle 502, causing the table top 1, base 505, and rotating base 500 to move toward the fixed base 501, rapidly engaging the first locking structure 513 and the second locking structure 514. Such arrangements achieve rapid locking and unlocking of the locking mechanism 5.

[0043] In some embodiments, the elastic member 507 may be a spring, which can be set in various forms. For example, as shown in FIGS. 4 and 6, the elastic member 507 is connected within the rotating shaft 4 and is sleeved over the connecting rod 506. One end of the elastic member 507 abuts against the rotating block 509, and the other end abuts against the base 505.

[0044] In some embodiments, the elastic member 507 may also be sleeved over the rotating shaft 4, with one end of the elastic member connected to the rotating shaft and the other end abutting against the end of the rotating base away from the fixed base.

[0045] Furthermore, the base 505 includes an annular connecting wall 508 which is slidably sleeved over the rotating shaft 4. When the table top 1 rotates relative to the rotating shaft 4, the annular connecting wall 508 rotates relative to the rotating shaft 4. Such arrangements make the structure between the base 505 and the rotating shaft 4 more compact. Moreover, the cooperation between the annular connecting wall 508 of the base 505 and the rotating shaft 4 makes the table top 1 flip more smoothly and improves movement stability.

[0046] In order to further ensure smooth rotation between the table top 1 and the rotating shaft 4, as shown in FIGS. 2 and 5, a mounting base 6 is connected to the bottom of the table top 1. The mounting base 6 is rotatably connected to the rotating shaft 4 and can slide along the axis direction of the rotating shaft 4. Therefore, under the cooperation between the mounting base 6 and the rotating shaft 4, and between the rotating base 500 and the rotating shaft 4, the rotation of the table top 1 is smoother and more stable.

[0047] The first locking structure 513 and the second locking structure 514 are coaxially arranged and are respectively disposed on opposite edges of the rotating base 500 and the fixed base 501. The locking structure may be integrally formed with the rotating base 500 or the fixed base 501, or may be connected to the rotating base 500 or the fixed base 501 via fasteners. In one implementation, as shown in FIG. 6, the first locking structure 513 and the second locking structure 514 are locked by a pair of tooth-engaging structures. That is, the pair of tooth-engaging structures are opposite edges, which both have teeth distributed in an annular manner and configured to engage with each other, of the first locking structure and the second locking structure. Specifically, an edge, which is close to fixed base 501, of the rotating base 500 is provided with annularly distributed teeth, while an edge, which is close to the rotating base 500, of the fixed base 501 is provided with teeth configured to engage with the teeth on the edge of the rotating base 500. When the teeth on the rotating base 500 engage with the teeth on the fixed base 501, the table top 1 is in a locked state; when the teeth on the rotating base 500 disengage from the teeth on the fixed base 501, the table top 1 is in an unlocked state.

[0048] In some implementations, the locking between the first locking structure 513 of the rotating base 500 and the second locking structure 514 of the fixed base 501 can also be locked by a pair of concave-convex snap-fit structures. Specifically, the first locking structure 513 may be a plurality of protrusions or notches distributed along the circumference of the rotating base 500, and the second locking structure 514 may be a plurality of notches or protrusions correspondingly distributed along the circumference of the end face of the fixed base 501.

[0049] In some implementations, the first locking structure and the second locking structure are locked by a pair of friction structures. As shown in FIG. 7, two friction disks 515 with rough friction surfaces are respectively connected to the two opposite end faces of the rotating base 500 and the fixed base 501. The friction surfaces can be a plurality of friction protrusions or a rough surface with alternating concave and convex surfaces.

[0050] In some implementations, as shown in FIG. 8, the first locking structure and the second locking structure are locked by a pair of clutch members. Specifically, the first locking structure 513 and the second locking structure 514 are locked by a pair of clutch plate 516. The end faces of the two opposite ends of the rotating base 500 and the fixed base 501 are respectively connected with two annular clutch plates 516, where the clutch plates 516 is an accessory of the prior art. When the clutch plate 516 on the rotating base 500 is pressed against the clutch plate 516 on the fixed base 501, the rotating base 500 as well as the table top 1 are locked, and when the clutch plate 516 on the rotating base 500 is out of contact with the clutch plate 516 on the fixed base 501, the rotating base 500 as well as the table top 1 are unlocked.

[0051] In some embodiments, as shown in FIGS. 4 and 6, a cover 400 may be connected to the rotating base 500 and is sleeved over the rotating shaft 4 and can cover the first locking structure 513 and the second locking structure 514. In addition, the cover 400 may be connected to the base 505 or connected between the rotating base 500 and base 505, and is sleeved over the rotating shaft 4 and can cover the first locking structure 513 and the second locking structure 514. The arrangements of the cover 400 serve to cover the first locking structure 513 and the second locking structure 514, preventing debris from entering between the two locking structures, and also ensuring safety in use.

[0052] In some embodiments, as shown in FIG. 1, a baffle 100 is connected to the side of the table top 1 close to the user, extending upward and extending out of the top surface of the table top 1. The arrangements of the baffle 100 can prevent items on the table top 1 from falling when the table top 1 is tilted.

[0053] Further, the baffle 100 may be hidden while the table top is adjusted as horizontal. In some embodiments, the baffle 100 is movably disposed in a groove of the table top 1. When the table top 1 is in a tilted state, the user may push the baffle 100 upward from the bottom of the table top 1 so that the baffle 100 protrudes from the upper surface of the table top 1, and the baffle 100 may be limited and fixed by fastening means such as a latch, a clamping block, or an elastic member, thereby preventing items from falling. When the table top 1 is adjusted to a horizontal state, the user may release the fastening means and press the baffle 100 downward so that the baffle 100 is flush with the upper surface of the table top 1, thereby avoiding interference with the use of the table top. In some embodiments, the baffle 100 may also be rotatably arranged. When the table top 1 is in a horizontal state or when the baffle is not needed, the baffle 100 may be rotated to be attached to the upper surface or side surface of the table top 1. When needed to prevent items from falling, the user may rotate the baffle 100 to a position forming a certain angle with the upper surface of the table top 1, thereby achieving a protective function.
