Anti-rollover swivel chair

Abstract

The invention discloses an anti-rollover swivel chair which comprises a driving rod, a connecting rod and an enlarged rod which are hinged in sequence. The driving rod is fixed at the lower end of a backrest, the enlarged rod has a middle connecting point, the enlarged rod is arranged on the lower surface of a cushion through the middle connecting point, and a torsion spring is arranged at the position of the middle connecting point. The anti-rollover swivel chair also includes a horizontally-arranged rhombic transmission support, and a pair of diagonal vertexes of the transmission support isconnected with a first rod and a second rod respectively. One side of the lower surface of the cushion far away from the backrest is provided with a sliding rail, the sliding rail is provided with a balance weight connected with the first rod, one side of the lower surface of the cushion close to the backrest is provided with a fixing ring, the second rod is disposed in the fixing ring, and the second rod is hinged to the enlarged rod. The lower surface of the cushion is also provided with a sliding groove perpendicular to the sliding rail, and the other pair of diagonal vertexes of the transmission support is disposed in the sliding groove. The anti-rollover swivel chair has an anti-rollover function and is good in safety and comfort.

Description

technical field [0001] The invention relates to a swivel chair, in particular to an anti-swivel chair. Background technique [0002] A swivel chair is a chair whose cushion part can be turned. With the development of economy and technology, people's living standards have improved, and at the same time, the production cost of swivel chairs has decreased. Therefore, more and more people use the swivel chair as the furniture choice for office or home. Compared with traditional chairs, swivel chairs have the obvious feature that they can be divided into three parts: cushion, support column and base. The gravity above the cushion part is only transmitted to the base through the support column. This structure has just caused the swivel chair to be not as stable as traditional chairs in terms of mechanics, and the problem of overturning easily occurs when people sit on the swivel chair and stretch their bodies. Existing swivel chairs lack both a reminder device for preventing ti...

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 and stretch their bodies, they are prone to overturning.

Existing swivel chairs lack both a reminder device for preventing tip-ups and a device for preventing tip-ups, and there are certain potential safety hazards

In addition, the user cannot stretch out on the chair with peace of mind, and the comfort of use will also be reduced

Therefore, existing swivel chairs have the problems of lack of anti-flip function, poor safety and comfort
