Chassis structure of swivel chair

Abstract

The invention discloses a chassis structure of a swivel chair. The chassis structure includes a bottom shell, a fixed seat and an elastomer structure; the bottom shell is fixedly arranged on the bottom of a cushion of the swivel chair, the fixed seat is arranged at the upper end of a pneumatic rod of the swivel chair, and the elastomer structure is connected between the outer side wall of the fixed seat and the inner side wall of the bottom shell and is in an elastic cylinder shape; the elastomer is designed to be an environment-friendly silicone tube with resilience force and can deform whenbeing affected by external force, therefore, an elastic connection structure can be formed between the bottom shell and the fixed seat and can generate relative motion, and a function of slightly swinging up and down can be achieved when a human body sits on the cushion and longitudinally swings up and down in either transverse direction of 360 degrees to drive the bottom shell to swing longitudinally; the middle of the fixed seat is provided with a mounting hole, and an air cylinder switch is arranged on the mounting hole; the chassis structure further comprises a lifting handle hinged to thebottom shell through a handle hinge pin, the lifting handle is provided with a hinge hole capable of being hinged with the handle hinge pin, and the upper end of the bottom shell is provided with a notch allowing the lifting handle to pass through; and the outer side face of the bottom shell is designed to be an arc-shaped inclined plane inclining towards the inner side from top to bottom.

Description

technical field [0001] The invention relates to the technical field of seats and accessories thereof, in particular to a chassis structure of a swivel chair. Background technique [0002] Swivel chairs are widely used in daily life, either for leisure and entertainment, or for office swivel chairs. However, the structural design of the swivel chairs currently on the market is relatively traditional and old, with cumbersome and complicated structures, many parts, many processes, and low production efficiency. Low, old and single function, the current swivel chairs on the market do not have functions such as swinging up and down, and the comfort needs to be improved. need. [0003] Therefore, how to realize a chassis structure of a swivel chair with rotation function, lifting function, slight up and down swing function, novel and diverse functions, effectively improving comfort, meeting different needs of users, simple and ingenious structure, simple processing procedure, and...
