Description

Technical Field

[0001] The utility model relates to a handrail structure. Background Art

[0002] The armrest of an existing office chair is composed of an armrest bracket and a panel arranged on the surface of the armrest bracket, and the panel and the armrest bracket are assembled using multiple screws. This structure assembled using screws requires a reserved hole at the bottom of the armrest bracket so that the screws can pass through the reserved hole and be threadedly connected to the panel during later assembly.

[0003] Based on the above, the existing installation method of reserving holes at the bottom of the handrail bracket will eventually result in multiple holes on the bottom surface of the handrail bracket. These holes will not only affect the aesthetics of the product, but also affect the integrity of the product appearance, and further improvement is needed. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a handrail structure with good aesthetics and good product surface integrity.

[0005] An armrest structure designed for this purpose includes an armrest bracket and an armrest panel, wherein the upper surface of the armrest bracket is provided with a plurality of snap-in holes, and the lower surface of the armrest panel is provided with a plurality of positioning columns that are plugged into the snap-in holes, and the lower end of the positioning column is provided with a snap-in piece, which is inserted into the inside of the snap-in hole and snap-fits with the hole wall of the snap-in hole.

[0006] Preferably, the clamping member comprises a connecting ring, on which a plurality of positioning elastic teeth are arranged in a circumferential array, and the positioning elastic teeth are clamped and matched with the hole wall of the clamping hole.

[0007] Preferably, the connecting ring and the positioning elastic teeth are an integrated structure.

[0008] Preferably, the positioning column is threadedly connected with a fixing screw, and the screw head of the fixing screw cooperates with the lower end surface of the positioning column to clamp and fix the connecting ring.

[0009] Preferably, a bottom plate is installed on the lower end surface of the armrest panel, and the bottom plate is provided with an avoidance hole at a position corresponding to the positioning column.

[0010] Compared with the prior art, the utility model has a plurality of snap-in holes on the upper surface of the armrest bracket, a plurality of positioning columns plugged into the snap-in holes on the lower surface of the armrest panel, and a snap-in piece on the lower end of the positioning column. The snap-in piece is inserted into the snap-in hole and snap-fitted with the hole wall of the snap-in hole. When assembling the utility model, the snap-in piece is first installed on the armrest panel, and then the armrest panel is plugged and assembled with the armrest bracket. During the plug-in process, the positioning column of the armrest panel drives the snap-in piece to be inserted into the snap-in hole. When the snap-in piece is plugged into the snap-in hole, the snap-in piece snaps into the hole wall of the snap-in hole to achieve a fixed connection between the armrest panel and the armrest bracket. This connection method using snap-in can save the reserved hole position to ensure the integrity of the product appearance and improve the aesthetics of the product.

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] See also Figure 1-Figure 6A handrail structure includes an handrail bracket 10 and an handrail panel 20, wherein the lower surface of the handrail bracket 10 is provided with a plurality of snap-in holes 110, and the upper surface of the handrail panel 20 is provided with a plurality of positioning columns 210 which are plugged into and matched with the snap-in holes 110, and the lower end of the positioning columns 210 is provided with a snap-in component 30, which is inserted into the snap-in hole 110 and snap-fitted with the hole wall of the snap-in hole 110. When the utility model is assembled, the clamping part is first installed on the armrest panel, and then the armrest panel and the armrest bracket are plugged and assembled. During the plugging process, the positioning column of the armrest panel drives the clamping part to be inserted into the inside of the clamping hole. When the clamping part is inserted into the inside of the clamping hole, the clamping part is clamped and matched with the hole wall of the clamping hole to realize the fixed connection between the armrest panel and the armrest bracket. This connection method using clamping can save the reserved hole position to ensure the integrity of the product appearance and improve the aesthetics of the product.

[0019] See also Figure 6 The clamping member 30 includes a connecting ring 310, on which a plurality of positioning elastic teeth 320 are arranged in a circumferential array, and the positioning elastic teeth 320 are engaged with the hole wall of the clamping hole 110. When the clamping member 30 is inserted into the clamping hole 110, the positioning elastic teeth 320 abut against the hole wall of the clamping hole 110 under the elastic action of the positioning elastic teeth 320 themselves, so as to constrain the relative position of the armrest bracket 10 and the armrest panel 20.

[0020] Furthermore, the positioning elastic teeth 320 arranged along the circumferential array can effectively increase the restraining force of the connection to ensure the stability of the connection.

[0021] In the present invention, the connecting ring 310 and the positioning elastic teeth 320 are an integrated structure.

[0022] Furthermore, the connection ring 310 and the positioning elastic teeth 320 are made of metal. The positioning elastic teeth 320 made of metal can effectively avoid the problem of breaking and affecting the connection stability.

[0023] See also Figure 3 and Figure 5 The positioning column 210 is threadedly connected with a fixing screw 330 , and the screw head of the fixing screw 330 cooperates with the lower end surface of the positioning column 210 to clamp and fix the connecting ring 310 .

[0024] See also Figure 2 and Figure 5 A bottom plate 40 is installed on the lower end surface of the armrest panel 20, and an avoidance hole 410 is arranged on the bottom plate 40 corresponding to the position of the positioning column 210. The function of the bottom plate 40 is to fix the edge of the leather on the bottom plate 40 by nailing after the armrest panel 20 is leathered.

[0025] Furthermore, the bottom plate 40 is fixedly mounted on the armrest panel 20 by means of screws.
