Headrest lifting adjustment integral base

Abstract

The invention relates to a headrest lifting adjustment integral base and aims to solve the technical problems that the prior art is unreasonable in design, and the like. The headrest lifting adjustment integral base comprises a stripy block, wherein the stripy block is integrally molded in an injection molding manner; a rectangular through hole which is formed in the axial direction of the stripyblock is formed inside the stripy block; a cantilever block is arranged in the middle of a side surface close to a human body, of the stripy block; a plurality of fixing holes are formed in the cantilever block; an inverted U-shaped groove is formed below the cantilever block in a side surface with the cantilever block, of the stripy block; a cantilever type locking elastic block is arranged inside the inverted U-shaped groove; the inverted U-shaped groove is communicated with the rectangular through hole; a semispherical convex part which protudes towards the rectangular through hole is arranged at a suspended end close to the rectangular through hole, of the cantilever type locking elastic block; limiting convex columns are arranged on both sides of one surface with the semispherical convex part of the cantilever type locking elastic block; the limiting convex columns are symmetrically arranged with the semispherical convex part as a center. The headrest lifting adjustment integral base has the advantage reasonable design.

Description

technical field [0001] The invention belongs to the technical field of chair accessories, and in particular relates to an integrated seat for lifting and adjusting a headrest. Background technique [0002] A swivel chair includes a chair frame, a seat cushion mounted on the chair frame, and a back, legs and headrest components. [0003] In order to be suitable for different groups of people, many existing headrest components are designed as a lifting structure whose position can be adjusted up and down. The lifting structure generally adopts the design of several convex points and several concave holes. The structure of the lifting adjustment seat is generally a C-shaped main body, and a cylindrical closing plate is formed by closing the C-shaped main body, and an elastic sheet and a locking convex point are designed on the closing plate. [0004] The above-mentioned solution needs to pass screws on the closing plate and process threaded holes on both sides of the C-shaped ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned solution needs to pass screws on the closing plate and process threaded holes on both sides of the C-shaped main body. Although this solution can meet the requirements of use, the production efficiency of this solution is reduced, and the strength of the entire structure is also reduced. It is still poor, and it is prone to upward detachment during the adjustment process, and the design is unreasonable
