Description

technical field [0001] The invention relates to a swivel chair, in particular to an easy-to-lock swivel chair. Background technique [0002] In recent years, more and more people regard swivel chairs as the first choice for configuration, no matter in the office or in the family. Compared with traditional chairs, swivel chairs have the obvious feature that they can be divided into three parts: cushion, support shaft and base. The gravity above the cushion part is only transmitted to the base through the support shaft. This structure has just caused the swivel chair to be not as stable as the traditional chair in terms of mechanics, and the problem of rollover is prone to occur when people sit on the swivel chair to stretch their bodies or pick up things sideways. Existing swivel chairs lack a rollover reminder device, causing users to be easily injured due to the rollover problem, and the safety is low. In addition, the connection between the universal wheels and the base ...

AI Technical Summary

Problems solved by technology

This structure leads to the fact that the swivel chair is not as stable as the traditional chair in terms of mechanics. When people sit on the swivel chair to stretch their bodies or pick up things sideways, they are prone to rollover problems.

Existing swivel chairs lack a rollover reminder device, causing users to be easily injured due to rollover, and the safety is low

In addition, the connection between the universal wheels and the base of the existing swivel chairs is rigid, and the cushioning performance of the chair is only realized by the softness of the cushion, which lacks vibration-absorbing ability, resulting in poor comfort of the chair

More commonly, after the universal wheels of swivel chairs are used for a period of time, the wheel shafts are stuck by debris such as hair and garbage, which makes the wheel shafts unable to rotate and reduces the flexibility of swivel chairs

On the other hand, the universal wheels of the current swivel chair either have no locking device or an independent locking device between the wheels, which makes the fixing of the swivel chair very troublesome and cannot meet the needs of users who need to fix the swivel chair

Therefore, the existing swivel chairs have the problems of poor safety, comfort and flexibility, and the locking of the swivel chairs is also troublesome.
