DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application discloses a stable and liftable bench. Figure 1 A stable and liftable bench comprises a chair leg 2, a chair body 1 and a seat cushion 3. The chair leg 2 is a vertical rod-shaped structure, one end of which is fixed to the ground and the other end is used to connect to the chair body 1. The seat cushion 3 is at least wrapped around the upper surface of the chair body 1. The chair body 1 and the chair leg 2 are both made of metal. The connection between the chair body 1 and the chair leg 2 is fixed by welding. The seat cushion 3 is composed of a leather outer layer and a sponge filled in the leather outer layer, which improves the comfort of the occupant. A mounting plate 4 is provided at the connection end between the chair leg 2 and the ground. The mounting plate 4 is arranged horizontally and has a mounting hole. A pre-tightening bolt is arranged in the mounting hole, and the lower end of the pre-tightening bolt is screwed into the ground, thereby fixing the chair leg 2 to the ground. It should be noted that in order to avoid the situation where the exposed part of the pre-tightening bolt is rusted due to the influence of water vapor when the bench is installed outdoors, measures such as spraying anti-rust paint on the surface of the pre-tightening bolt can be adopted to prevent the connection between the pre-tightening bolt and the mounting plate 4 from rusting and being difficult to twist.

[0035] Reference Figure 2 and Figure 3 The chair leg 2 adopts a telescopic structure, which consists of a main body 21 and a telescopic part 22. The telescopic part 22 is inserted into the main body 21 and can slide along the height direction of the main body 21 to achieve lifting and lowering. The chair body 1 is arranged at the end of the telescopic part 22 away from the main body 21, and the mounting plate 4 is arranged at the end of the main body 21 away from the telescopic part 22, so as to form a structure in which the main body 21 remains fixed and the height of the chair body 1 is adjusted by adjusting the distance that the telescopic part 22 extends out or retracts into the main body 21. A locking member 23 is arranged between the main body 21 and the telescopic part 22, which is used to fix the relative position of the main body 21 and the telescopic part 22 after the height adjustment of the chair body 1 is completed.

[0036] Specifically, the locking member 23 is a fastening bolt, and nuts are screwed on both ends of the fastening bolt. Multiple locking holes that match the fastening bolts are provided on both sides of the main body 21 and the telescopic part 22. The multiple locking holes are arranged at intervals along the height direction of the main body 21 and the telescopic part 22, wherein four locking holes that are coaxially arranged in the same horizontal plane form a group, and the axis of the group of locking holes intersects and is perpendicular to the central axis of the telescopic part 22. The locking member 23 penetrates from one of the locking holes on one side of the main body 21, passes through two locking holes coaxial with the locking hole and provided on the telescopic part 22, and then penetrates from the corresponding locking hole on the other side of the main body 21. Both ends of the locking member 23 extend to the outside of the main body 21, and the connection between the main body 21 and the telescopic part 22 is achieved by tightening the nuts on both ends of the locking member 23 and abutting against the outer surface of the main body 21.

[0037] The telescopic part 22 and the main body 21 are preferably hollow cylindrical structures to reduce their own weight. Further, a support tube 221 is provided inside the telescopic part 22, the support tube 221 extends horizontally and intersects with the central axis of the telescopic part 22, the support tube 221 is a hollow structure with two ends open, the telescopic part 22 is connected to the support tube 221 in an integral manner, and the locking holes provided on both sides of the telescopic part 22 in the above-mentioned same group are respectively formed at the two ends of the support tube 221. When the locking member 23 connects the main body 21 with the telescopic part 22, the part of the locking member 23 extending into the telescopic part 22 is penetrated into the support tube 221 and contacts the inner wall of the support tube 221. The use of this structure can reduce the self-weight of the telescopic part 22 while increasing the contact area between the locking frame and the telescopic part 22, reducing stress concentration, thereby preventing the locking member 23 from being subjected to long-term pressure, resulting in damage or even breakage of the connection with the telescopic part 22.

[0038] Reference Figure 4 , Figure 5 and Figure 6The chair body 1 is a roughly long strip structure, consisting of a plurality of base plates 11 connected end to end. Each base plate 11 can be set to a straight line or a curve, as long as it can be connected to the other two adjacent base plates 11. Therefore, the specific shape of each base plate 11 is not limited. The two adjacent base plates 11 are connected by a connecting structure 12. The connecting structure 12 includes two groups of connecting plate groups 122 symmetrically distributed along the center line of the chair body 1, and a connecting rod 121 connecting and fixing the two groups of connecting plate groups 122. The two ends of the connecting rod 121 pass through the two groups of connecting plate groups 122 respectively, and fixing plates 123 are provided at both ends of the connecting rod 121. Each group of connecting plate groups 122 includes two ear plates 1221 that are staggered front and back. The upper ends of the two ear plates 1221 are respectively welded to the lower surfaces of the two adjacent sections of the base plate 11, and the lower ends are inclined toward the center lines of the two ear plates 1221 with the same inclination angle. Each ear plate 1221 is provided with a through hole that is arranged to cooperate with the connecting rod 121. The through holes opened on the ear plates 1221 of the corresponding two groups of connecting plate groups 122 are interconnected to allow the connecting rod 121 to pass through and out.

[0039] Furthermore, the two ends of the connecting rod 121 extend out to the side away from the two connecting plate groups 122, and the two fixing plates 123 arranged at the two ends of the connecting rod 121 abut against the outer sides of the two connecting plate groups 122, respectively, to limit the positions of the two connecting plate groups 122, thereby improving the connection strength of the two adjacent sections of the base plate 11. In order to achieve the disassembly and assembly effect, the fixing plate 123 at at least one end of the connecting rod 121 can be set as a structure threadedly connected to the connecting rod 121, specifically, a threaded hole extending inwardly along the axial direction is opened on the end face of the connecting rod 121, and a threaded column 1231 is formed on the side of the fixing plate 123 facing the connecting rod 121. When the threaded column 1231 is completely screwed into the threaded hole, the fixing plate 123 just abuts against the end face of the connecting rod 121, and at the same time abuts against the ear plate 1221 located on the outside.

[0040] It should be noted that, in order to facilitate the threaded connection between the fixing plate 123 and the connecting rod 121, a specific connection method should be adopted between the connecting rod 121 and the ear plate 1221, which satisfies that the connecting rod 121 can slide along the axial direction but cannot rotate around the axis, so that when the fixing plate 123 is rotated to be threadedly connected with the connecting rod 121, the connecting rod 121 can remain stationary. The connection method can be specifically formed with a key extending along the axial direction of the connecting rod 121, and each ear plate 1221 is correspondingly provided with a key slot corresponding to the key, and when the connecting rod 121 is inserted into the ear plate 1221, the key is matched in the key slot, thereby limiting the rotation of the connecting rod 121 around the axis.

[0041] Furthermore, the connecting structure 12 also includes a wear-resistant pad 1222, which is arranged between two ear plates 1221 of the same connecting plate group 122, and is used to increase the friction between the two ear plates 1221, improve the connection stability, and reduce the wear of the two ear plates 1221 on the side close to each other during the use of the bench.

[0042] Reference Figure 4 A threading hole is provided on the surface of at least one section of the substrate 11, a wire groove 6 is provided inside the substrate 11, and cables are laid in the wire groove 6. One end of the cable passes through the threading hole and out of the substrate 11 to be connected to an external power supply. A power socket 5 is installed on one side of the substrate 11, and the other end of the cable is connected to the power socket 5 to enable current transmission.

[0043] Furthermore, a protective cover 7 is installed at the position of the base plate 11 corresponding to the power socket 5. The lower end of the protective cover 7 is rotatably connected to the base plate 11, so that the protective cover 7 can be rotated in a direction close to or away from the base plate 11, and the upper end of the protective cover 7 is engaged with the base plate 11. When the user needs to use the power socket 5, the protective cover 7 can be opened to expose the power socket; after use, the protective cover 7 can be closed to hide the power socket. The user's charging needs for electrical devices such as mobile phones are met, and when not in use, the power socket is protected by the protective cover 7.

[0044] Each section of the base plate 11 is also connected to a tray 9. The tray 9 is preferably a disc-shaped structure for placing objects or for passengers to place their arms. A support rod 8 is provided between the tray 9 and the base plate 11. One end of the support rod 8 is fixedly connected to the base plate 11, and the other end extends vertically upward to connect with the tray 9. It can be understood that the support rod 8 provides stable support for the tray 9, and the central axis of the support rod 8 should be set to coincide with the central axis of the disc. In addition, in order to improve the practicality of the tray 9, a recessed placement groove can be formed on the surface of the tray 9. When the user places an item in the placement groove, it can play a certain limiting role and prevent the placed item from sliding off the tray 9.

[0045] The implementation principle of a stable and liftable bench in an embodiment of the present application is as follows: when connecting the sections of the base board 11, the sections of the base board 11 are connected end to end, and the ear plates 1221 arranged on both sides of each section of the base board 11 are staggered with the ear plates 1221 on both sides of another adjacent section of the base board 11. Then, the connecting rod 121 is inserted into the two groups of connecting plate groups 122, and the fixing plate 123 is threadedly connected to the end of the fixing plate 123, thereby connecting the sections of the base board 11.

[0046] When the overall height of the bench needs to be adjusted, the fixing plate 123 needs to be loosened and removed, the connecting rod 121 needs to be removed, the connecting structure 12 between the sections of the base plate 11 needs to be released, and then the locking piece 23 connecting the main body 21 and the telescopic part 22 needs to be removed. The telescopic parts 22 can be raised or lowered in turn as needed. After adjusting to the required height, the locking piece 23, the connecting rod 121, the fixing plate 123, etc. need to be reinstalled.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
