DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0040] The following description will refer to the accompanying drawings to more fully describe the contents of the present application. It is apparent that here only constitutes a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment One

[0041] Referring to FIGS. 1-7, the embodiment of the present invention discloses a telescopic rod structure, which is applied to an immovable body and at a same time applied to a movable body. A side edge of the movable body is rotatably connected to the immovable body, and in present embodiment, the movable body is a cover body. The telescopic rod structure includes a telescopic rod 1, a fixing piece 2 and a movable piece 3. The telescopic rod 1 includes a sleeve 101 and a piston rod 102 slidably connected to the sleeve 101, the piston rod 102 is driven to slide in the sleeve 101 so that the telescopic rod 1 can be extended or shortened. The fixing piece 2 has a first end and an opposite second end, the fixing piece 2 is fixedly mounted in a fitting manner on an immovable body, and the first end of the fixing piece 2 is hinged with the end of the piston rod 102. The movable piece 3 is fixedly arranged on the cover body in a fitting manner, and the end of the movable piece 3 is hinged with the second end of the fixing piece 2. The movable piece 3 is also provided with a connecting portion 30 configured for being hinged with the end of the sleeve 101. In particular, the fixing piece 2 and the movable piece 3 each are in a strip shape, and each of the fixing piece 2 and the movable piece 3 is in surface contact with corresponding objects, i.e. when the two ends of the telescopic rod 1 are released from the stressed object, the point contact is converted into a strip-shaped surface contact, so that the two ends of the telescopic rod 1 cannot directly press the cover body and the immovable body, the cover body and the immovable body are prevented from being extruded and deformed by pulling force, thereby achieving the purpose of prolonging the service life.

[0042] Furthermore, the telescopic rod 1, the movable member 3 and the fixing piece 2 enclose a transformable triangular structure 4, and the triangular structure 4 has a first state in which it is unfolded into a triangular shape, and a second state in which it is folded into a strip shape, when the telescopic rod 1 is driven to extend, the triangular structure 4 is switched to the first state, when the telescopic rod 1 is driven to shorten, the triangular structure 4 is switched to the second state. In particular, the first state is generally for supporting the cover body, the telescopic rod structure is capable of being applied to a corresponding object by forming a stable triangular structure 4, so that the cover body can be stably supported. The second state is generally at when the cover body is in the closed state. The telescopic rod structure is also capable of transforming the triangular structure 4 into a folded second state, thereby achieving the purpose of saving space.

[0043] According to the technical scheme, the telescopic rod structure can be applied to various cover bodies, such as a box cover, an automobile engine and a front cover, a cabinet, a cabinet door and the like. By articulating, that is hinging the fixing piece 2 and the movable piece 3 at both ends of the telescopic rod 1, and articulating the movable piece 3 with the fixing piece 2, the three form the triangular structure 4. By virtue of the fact that the telescopic rod 1 can be extended and shortened, such that the triangular structure 4 can be switched between a first state and a second state, such that the cover can be stably supported when the triangular structure 4 is in the first state; and the triangular structure 4 can be better accommodated by the cover body in the second state. At the same time, the fixing piece 2 and the movable piece 3 are arranged on the immovable body and the cover body in a surface contact manner, thereby solving the traditional problem of tensile deformation of objects that in point contact with two ends of the telescopic rod 1, and the service life of the telescopic rod structure and the article applying the telescopic rod structure is prolonged.

[0044] It should also be noted that in this embodiment, the telescopic rod 1 is a hydraulic or pneumatic rod, which allows the telescopic rod 1 to automatically extend or shorten when extended or shortened to a certain distance under internal hydraulic or pneumatic drive, making it easy for the user to control the corresponding cover.

[0045] Due to the fact that the telescopic rod structure can be applied to different types of cover bodies, the weight of the cover body varies. When dealing with lighter cover bodies, the user can easily lift the cover body, the telescopic rod 1 itself can help lift the cover body. When dealing with heavier cover bodies, the user will have difficulty flipping the cover body. Therefore, the telescopic rod structure provided in this embodiment also includes elastic member 5, which is set on the piston rod 102. When the triangular structure 4 is in the second state, the elastic member 5 is in a compressed state under the force of the sleeve 101. Specifically, the elastic member 5 is a compressed elastic member 5. When the triangular structure 4 is in the first state, the elastic member 5 is not under force. When the telescopic rod 1 gradually shortens, the end of the sleeve will contact and compress the elastic member 5. When the telescopic rod 1 shortens to the minimum length, the elastic member 5 is in a compressed state, and the triangular structure 4 is in the second state, in which the cover body is closed and an immovable body is closed. When the user wants to lift the cover body to open, while flipping the cover body, the telescopic rod 1 extends, and the elastic potential energy of the elastic member 5 is released, thereby assisting the telescopic rod 1 in extending to assist the cover body change to be open, reducing the force required for the user to open the cover body and making it easier for the user to lift the heavier cover body.

[0046] In order to make the telescopic rod structure more reasonable and stable when applied to immovable bodies and cover bodies, as shown in FIG. 2 and FIG. 5, the fixing piece 2 includes an connecting section 21 and a transition section 22 integrally formed with the connecting section 21, and the fixing piece 2 is in a Z-shaped shape as a whole. The connecting section 21 is provided with multiple holes for installation, and the end of the transition section 22 is used to hinge with the movable piece 3. Specifically, the connecting section 21 can be fitted onto the inner wall of an immovable body by passing through the hole position with screws. In this embodiment, the length of the connecting section 21 is greater than the minimum length of the telescopic rod 1, so that when the triangular structure is in the second state, the telescopic rod structure is more compact.

[0047] Furthermore, the movable piece 3 includes a first receiving section 31 and a second receiving section 32 that are integrally formed. The first receiving section 31 is provided with a receiving groove 310 for receiving the sleeve 101, and the bottom of the receiving groove 310 is provided with multiple holes for installation. The second receiving section 32 has a hollow portion at a middle part thereof. When the triangular structure 4 is in the second state, the sleeve 101 is received in the receiving groove 310, and the transition section 22 is received in the hollow portion of the second receiving section 32. Specifically, the outer wall of the receiving groove 310 is attached to an immovable body and fixed with screws for installation. The receiving groove 310 and the hollow portion of the second receiving section 32 make the telescopic rod structure more compact, without affecting the complete closure of the cover.

Embodiment Two

[0048] Referring to FIGS. 8-28, the embodiment of this present invention also discloses an adjustable box for storing items. The adjustable box includes a bottom plate 7, a plurality of side plates 8 and the aforementioned telescopic rod structure 6. The bottom plate 7 is detachably connected with the side plates 8 which are vertically arranged, to fix the position of the bottom of the side plate 8. Multiple side plates 8 are combined into a circle and cooperate with the bottom plate 7 to form a space for storage. The top of the side plate 8 is detachably connected with a frame body 9, to fix the position of the top of the side plate 8. The frame body 9 is rotatably connected with a cover body 10 for covering and accommodating space. The telescopic rod structure 6 is located between the cover body 10 and the frame body 9. When the cover body 10 is opened, the triangular structure 4 is in the first state, and the telescopic rod structure 6 can support the cover body 10. When the cover body 10 is closed, the triangular structure 4 is in the second state. There are multiple types of bottom plates 7, and different types of bottom plates 7 have different sizes. The Side plates 8, frame body 9, and cover body 10 each have sizes corresponding types of bottom plate 7. By replacing different types of bottom plates 7, the size of the accommodating space can be adjusted.

[0049] In the actual use process, according to the usage scenario and actual needs, select a bottom plate 7 with appropriate length and width, connect and fix the side plate 8 with appropriate height on the bottom plate 7, and make all side plates 8 enclose a circle. At this time, the bottom plate 7 and side plate 8 can form a space for accommodating items. Then, install the suitable frame body 9 on the top of the side plate 8 to completely fix the side plate 8, and then install the cover body 10 on the frame body 9, and install the telescopic rod structure 6 between the cover body 10 and the frame body 9 to complete the assembly of the disassembled combination box. At this time, the telescopic rod structure 6 can assist the cover body 10 in opening and closing. Due to the detachable connection between the various components of the disassembly combination box, each component can be disassembled when not in use, reducing the space occupied during storage. At the same time, there are various types of bottom plate 7 with different sizes, and side plate 8, frame body 9, and cover body 10 each have corresponding size types of bottom plate 7, therefore, different sizes of components can be flexibly selected for assembly according to the application scenario and actual needs during use, and the size of the disassembled and assembled box can be adjusted accordingly. Concluded from the above, the disassembled combination box is easy to store and can be adjusted in size.

[0050] The above scheme has already explained that there are multiple types of bottom plates 7, and different types of bottom plates 7 have different sizes. However, in addition to the size, the type of bottom plate 7 can also be changed by changing the shape. Therefore, in this embodiment, the following design has been carried out. Specifically, different types of bottom plates 7 have different shapes, and side plates 8, frame body 9, and cover body 10 each have corresponding shape types of bottom plate 7. By replacing different types of bottom plates 7, the size of the accommodating space can be changed. The above scheme does not limit the shape of the bottom plate 7, which can be a triangle, rectangle, or polygon. In this embodiment, the most common rectangle in the box is used as an example.

[0051] In order to more conveniently connect and fix the side plate 8, the following design has been carried out in this embodiment. Specifically, the top of the bottom plate 7 is provided with a lower slot 11, and the bottom of the frame body 9 is provided with an upper slot 12. The bottom of the side plate 8 is inserted into the lower slot 11, and the top is inserted into the upper slot 12. Additionally, the side plate 8 can be detachably connected to the bottom plate 7, and the side plate 8 can be detachably connected to the frame body 9 through threaded connections. Through the design of the above structure, the bottom of side plate 8 can be inserted into the lower slot 11 for approximate limit, and then the top of side plate 8 can be inserted into the upper slot 12 for approximate limit. After that, it is fixed with bolts, which is simple and convenient to operate, saves time required for positioning, and is more firmly connected.

[0052] Due to the various types and sizes of the bottom plate 7, if the side plate 8 is also set with a type corresponding to the size of the bottom plate 7, the processing cost is too high and it is difficult to find during assembly. Therefore, in this embodiment, the design is as follows: the side plate 8 has a first end and a second end that are far away from each other in the horizontal direction, the first end of the side plate 8 is provided with a first plug plate 81, the second end is provided with a first slot 82, and the first plug plate 81, the first slot 82 and the side plate 8 are located on the same plane, and different side plates 8 can be connected together through the first plug plate 81 and the first slot 82. Through the design of the above structure, the size types required for side plate 8 can be greatly reduced, only need to simply plug and combine different side plates 8 together to match the length and width of the bottom plate 7.

[0053] It should be noted that the material of side plate 8 is not limited in the above scheme. Therefore, when side plate 8 is made of flexible materials, such as plastic, the size of side plate 8 can also be adjusted by cutting.

[0054] Due to the hollow nature of frame body 9, it occupies a large storage area and is inconvenient to install when combined with side plate 8. To solve these problems, the structure of frame body 9 has been designed as follows in this embodiment. Specifically, the bottom plate 7 is arranged in a rectangular shape, and frame body 9 includes two first frame portions 91 and two second frame portions 92. The bottom of the first frame portion 91 can be detachably connected to the side plate 8, and the bottom of the second frame portion 92 can be detachable connected to the side plate 8. The first frame portion 91 and the second frame portion 92 are vertically arranged and detachably connected to each other, thereby enclosing the frame body 9. Through the design of the above structure, the frame body 9 can be disassembled into strips, which greatly reduces the storage area. At the same time, when combined and installed, it can be connected to the side plate 8 on one side first, making it more convenient.

[0055] In order to achieve a detachable connection between the first frame portion 91 and the second frame portion 92, the following design has been carried out in this embodiment. Specifically, the first frame portion 91 is provided with buckle heads 93 at both ends, and the second frame portion 92 is provided with buckle seats 94 at both ends. The buckle heads 93 can be inserted into the buckle seats 94 to make the first frame portion 91 and the second frame portion 92 buckle connected. By using the above method, the overall firmness of frame body 9 can be ensured, while being easy to disassemble.

[0056] Although the bottom and top of side plate 8 are both restrained and fixed, deformation and other situations may occur on the sides. At the same time, there are usually gaps between adjacent side plates at the corners, which affect the overall sealing of the disassembled combination box. To solve the above problems, the following design was carried out in this embodiment, specifically including multiple first adapters 13, the first adapter 13 is vertically arranged and each first adapter 13 is detachably connected to two adjacent side plates 8 with an angle. The top of the first adapter 13 is connected to the frame body 9, and the bottom is connected to the bottom plate 7. Through the design of the above structure, the overall sealing and corner stability of the disassembled combination box have been enhanced, making the side plate 8 less prone to deformation.

[0057] There are various ways in which the first adapter 13 and side plate 8 can be detachably connected. In this embodiment, one of the connection methods is introduced: a first slot 82 corresponding to the first plug 81 and a second plug corresponding to the first slot 82 can be set on the first adapter 13, so that the first adapter 13 and side plate 8 can be connected by inserting in the slots.

[0058] There are various ways to rotate and connect the cover body 10 and the frame body 9, but most of the structures are not easy to disassemble and cannot be used in conjunction with the disassembly combination box mentioned above. In order to make the cover body 10 and the frame body 9 more convenient for disassembly and assembly, the following design has been carried out in this embodiment. Specifically, a second adapter 14 is also detachably connected to the frame body 9 and rotatably connected to the cover body 10, enable quick disassembly and assembly of the cover body 10 with the frame body 9 through the second adapter 14.

[0059] In order to enhance the safety of the disassembled combination box and prevent the cover body 10 from being bumped open during transportation, the following design has been carried out in this embodiment: a first fixing member 15 is also provided, which can be detachably connected to the cover body 10. One end of the first fixing member 15 extends out of the cover body 10, and a second fixing member 16 corresponding to the first fixing member 15 can be detachably connected to the frame body 9. The first fixing member 15 and the second fixing member 16 are provided with corresponding through holes 17 at one end that extends out of the cover body 10, which can be used in conjunction with locks to limit the cover body 10 when the cover is closed to accommodate space. In addition, the connection parts between the various components in this embodiment are located within the accommodation space, which can prevent other personnel from disassembling the disassembly combination box from outside.

[0060] In addition, the bottom plate 7, frame body 9, and cover body 10 in this embodiment are all provided with grid grids, which can enhance the stability of the above components, prevent deformation, and have stronger load-bearing capacity. The side plate 8 and the first adapter 13 in this embodiment are both hollowed out internally, which can significantly reduce weight and save manufacturing costs.
