Swivel chair leg

Abstract

The invention belongs to the technical field of swivel chair fittings, particularly relates to a swivel chair leg, and aims at solving the problem that the design is unreasonable in the prior art. Theswivel chair leg comprises a five-foot body; an axle hole is formed in the center of the five-foot body; strip-shaped grooves which are formed along the length directions of supporting feet of the five-foot body are formed in the supporting feet; recessed bulges corresponding to the strip-shaped grooves are arranged on the lower surfaces of the supporting feet; arc-shaped reinforcing blocks are arranged between the ends, close to the axle hole, of the recessed bulges and the supporting feet; reinforcing ribs are arranged between the arc-shaped reinforcing blocks and the recessed bulges; the arc-shaped reinforcing blocks form a ring; the lower end of the axle hole is connected with an extension cylinder; reinforcing rib bodies are respectively arranged between the arc-shaped reinforcing blocks and the extension cylinder and between the extension cylinder and the ends, close to the axle hole, of the supporting feet; and the reinforcing rib bodies are circumferentially and uniformly distributed. The swivel chair leg has the advantages of reducing the cost and providing relatively high structural strength.

Description

technical field [0001] The invention belongs to the technical field of swivel chair accessories, in particular to a swivel chair foot. Background technique [0002] Swivel chairs, including chair legs, cushions and backrests and other parts. [0003] The chair legs are made of metal and plastic, or a combination of metal and plastic. [0004] In the chair legs made of plastic, the chair legs are generally hollow structures, and in order to enhance the structural strength, generally a lot of grid reinforcing ribs are added on the lower surface of the chair legs, especially the lower surface of the legs of the chair legs. [0005] Although the above-mentioned structure can meet the requirements of service strength, the disadvantages of the chair foot of this structure are: [0006] Mold development is more difficult, resulting in higher initial investment costs. [0007] Second, the material input is relatively high, resulting in high production costs. Contents of the inv...
