Description

Technical Field

[0001] The utility model relates to the technical field of chair assembly, in particular to a connecting piece used for connecting armrests with a chair. Background Art

[0002] When the armrests are installed on the chairs on the market, a U-shaped connector is usually used to fix the backrest, and then the bottom surface of the armrest is connected through the two ends of the connector. Since the U-shaped connector is used to assemble the backrest and the armrest as one piece, and since the armrest protrudes from the seat surface when the chair is used with the chair, the armrest is very likely to be damaged or deformed by the connector due to weight or external force when the chair is used incorrectly, so the connector and the armrest need to be replaced. Since the connector is U-shaped as one piece, the entire connector needs to be disassembled when replacing it, which makes it inconvenient to repair the chair and increases the repair cost of the chair.

[0003] Therefore, in order to facilitate the disassembly, replacement and maintenance of the armrest support and the chair, the armrest bottom support and the chair are detachably assembled, which results in the formation of protrusions or angular edges at the connecting end of the armrest support and the chair. There is a risk of the protrusion or edges injuring the user when using the chair, which brings certain insecurity to the use of the chair.

[0004] Therefore, the utility model provides a connecting piece for connecting the chair to the armrest, which is used to protect the connection between the chair and the armrest support. Summary of the invention

[0005] The purpose of the utility model is to provide a connecting piece for connecting an armrest with a chair, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A connector for connecting an armrest to a chair, comprising a connector body, wherein a cavity is provided inside the connector body for connecting an armrest support to a chair connection end, and a support through hole and a chair connection through hole are provided at the front end and the inner side surface of the connector body respectively;

[0008] An assembly hole connected with the cavity is arranged on the outer side of the connecting piece body, and a decorative plate covering the assembly hole is arranged corresponding to the assembly hole.

[0009] Furthermore, an embedding groove is provided on the outer side of the connecting member body at the outer edge of the assembly hole, and the depth of the embedding groove is consistent with the thickness of the decorative panel. The decorative panel is embedded in the embedding groove and the outer surface of the decorative panel is on the same plane as the outer side of the connecting member. The decorative panel is embedded in the embedding groove to cover the assembly hole, thereby achieving the purpose of covering the locking armrest support and chair connection bolts in the assembly hole, thereby maintaining a neat effect on the assembled appearance of the chair.

[0010] Furthermore, the embedding groove corresponds to the left and right sides of the assembly hole, and the limiting plug rods on both sides of the inner side of the decorative panel are plugged and fixed with the limiting plug holes. After the bolts in the assembly hole lock the armrest support on the chair, the limiting plug rods on the inner side of the decorative panel are plugged with the limiting plug holes in the embedding groove, so that the decorative panel is confined in the embedding groove to cover the assembly hole.

[0011] Furthermore, the rear side of the connector body is arc-shaped, which reduces the edges and protrusions at the connection between the armrest and the chair, thereby avoiding injury or discomfort to the user and improving the rounded effect of the connector body.

[0012] Furthermore, the outer side of the connecting member body corresponding to the through hole of the support member is inclined at 45°, and the 45° inclination of the slope plays a transition role between the front end of the connecting member body and the through hole of the support frame, thereby reducing the edge angle of the connection between the connecting member body and the handrail support member.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The connector for connecting an armrest to a chair is provided with a support member through hole and a chair connection through hole which are connected to the internal cavity of the connector body. When assembling the chair and the armrest, the connecting end of the armrest support member is inserted through the support member through hole and is located in the cavity. Bolts are sequentially inserted through the assembly hole on the connector body and the through hole of the armrest support member connecting end and are spirally fixed to the outer side of the chair backrest, so as to achieve the purpose of quickly fixing the armrest support member to the chair. The bolts threaded on the connector body are covered and shielded by the decorative plate to maintain the overall neatness of the connector body. While having the effect of quickly assembling the armrest in cooperation with the chair, the protrusion and edges at the connection between the armrest and the chair are reduced by the arc shape and the inclined slope of the outer side of the connector body, so as to improve the roundness of the connection between the armrest and the chair, and avoid the protrusion and edges formed at the connection between the armrest and the chair causing harm to the user.
