AI Technical Summary
During the use of the existing office chair chassis, the strength of the bracket is low due to the planar structure at the edge of the bracket, which affects the support strength of the bracket for a long time, and the connection between the iron pipe and the mounting seat is unstable.
An office chair chassis control mechanism is designed to form a reinforcement structure by fixing the reinforcing edges at the edges of the front and rear ends of the bracket, and fixing the reinforcing ribs on the inner wall of the reinforcement edges. At the same time, the conical disc and iron pipe on the mounting base are arranged to be integrally formed with the mounting base, and a connecting plate is installed at the connection between the control handle and the bracket to improve the connection stability of the iron tube and the conical disc and the mounting base.
The strength of the bracket is improved by strengthening the edges and reinforcement ribs, forming a more stable support structure, increasing the support strength of the bracket; at the same time, through the design of the integrated molded cone disc and iron pipes and connecting plates, the stable connection between the iron pipes and cone disc and mounting seats is ensured, and the stability of the use of the entire bracket is improved.

[0005] The utility model aims to provide an office chair chassis control mechanism, which has the advantages of increasing the strength of a bracket, forming a reinforced structure of the bracket, thereby improving the supporting strength of the bracket, and secondly making the connection between the iron pipe, the cone disk and the mounting seat more stable, thereby further realizing the stability of the bracket when in use.
[0006] To achieve the above object, the utility model provides the following technical solutions: an office chair chassis control mechanism, comprising a bracket, a mounting seat is fixedly connected to the middle of the bracket, a control handle is installed on the left side of the mounting seat that penetrates and extends to the outside of the bracket, a cone disk is integrally formed on the upper end surface of the mounting seat, and an iron pipe is integrally formed on the inner wall of the cone disk;
[0007] The edges of the front and rear ends of the bracket are fixedly connected with reinforcing edges in a flanged structure.
[0008] In order to improve the strength of the reinforced edge, as a preferred embodiment of the office chair chassis control mechanism of the utility model, the inner wall of the reinforced edge is fixedly connected with a reinforcing rib.
[0009] In order to reinforce the connection between the control handle and the bracket, as a preferred embodiment of an office chair chassis control mechanism of the utility model, a connection plate is installed at the connection between the control handle and the inner wall of the bracket.
[0010] In order to install and connect the bracket to the chair, as a preferred embodiment of the office chair chassis control mechanism of the utility model, a threaded hole is opened on the surface of the bracket.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] The utility model firstly increases the strength of the bracket by fixing the reinforcing edges at the edges of the front and rear ends of the bracket, so that the bracket forms a reinforcing structure, thereby improving the supporting strength of the bracket;
[0013] Secondly, the cone disk and the iron pipe on the mounting seat are arranged to be integrally formed with the mounting seat, so that the connection between the iron pipe, the cone disk and the mounting seat can be more stable, thereby further achieving the stability of the bracket when in use.
