Protection air bag type lifting chair

Abstract

A protection air bag type lifting chair comprises a chair cushion, a pressing rod, a support, a support steel plate, a screw rod, an inner steel pipe and an outer steel pipe, a pivot of the pressing rod is fixed to the side wall of the support, the bottom of the inner steel pipe is fixed to the outer steel pipe through a plug and a sealing ring on the top of the outer steel pipe, the screw rod capable of freely moving is arranged in the inner steel pipe, the end, in the support, of the pressing rod is connected with the top end of the screw rod, an elastic buffering layer is arranged in the support, the edge of the elastic buffering layer is embedded in the inner wall of the support, a protection air bag is arranged on the top of the screw rod, the edge of the protection air bag is fixed between the support and the inner steel pipe, when an explosion happens in the lifting the chair, a user can be effectively prevented from being hurt by the explosion due to inappropriate using of the lifting chair through the protection air bag installed on the screw rod and the elastic buffering layer arranged at the upper portion of the protection air bag part, and the personal safety of the user is guaranteed.

Description

technical field [0001] The invention belongs to the field of household furniture, in particular to a protective airbag type lift chair. Background technique [0002] With the continuous development of scientific and technological progress, people have higher and higher requirements for seats in their daily life, and most of the work of human beings is done by sitting on chairs. In the development process of designing chairs, in order to be able to adapt to different table heights and to cater to the comfort of users, a pneumatic lift chair was invented. Pneumatic lift chairs can use gas as the working medium through gas springs, and can act as elastic elements for supporting, buffering, braking, height adjustment and angle adjustment. It is composed of pressure tubes, pistons, piston rods and several connectors. The working principle of the pneumatic lift chair is to press an inert gas, such as nitrogen, into a closed cavity to make the pressure in the cavity greater th...

AI Technical Summary

Problems solved by technology

However, in the process of producing pneumatic lift chairs, manufacturers pursue low prices while not strictly controlling the quality of the lift chairs. There are often phenomena such as insufficient nitrogen purity and substandard screw materials.

In addition, in the process of using the seat, frequent height adjustment and rotation of the seat or the overheating and explosion of the pressure part under the seat due to the long service life of the seat will cause severe personal injury, and even seriously endanger the User's life safety

On the one hand, this situation is due to the fact that the merchants use inferior materials, but in the final analysis, the lift chair lacks corresponding protection devices. Consumers do not have a good protection mechanism in the process of using the seat, which has buried hidden dangers for the safety of users.
