What's wrong with the lift chair? It won't rise. How should I fix it?

The lifting of the lifting chair is mainly realized by the lifting device at the lower part of the chair surface. At present, lifting equipment is mainly divided into three categories: hydraulic, mechanical and pneumatic.

There may be three reasons why the lift chair can't rise:

1, the adjusting handle and the connected adjusting mechanism are broken;

2. The pneumatic rod is broken;

3. Someone in the seat can't get up under pressure. It should be empty when it goes up, and it should be loaded when it goes down.

If it is the first two cases, you have to find a merchant or manufacturer to repair it.

The invention relates to a novel chair, which is mainly composed of a seat plate, a backrest, a bracket, a bracket rocker arm, a lifting positioning device and a chair foot, and is characterized in that the bracket and the chair foot are correspondingly hinged through the bracket rocker arm, and the bracket rocker arm rotates up and down around a hinge shaft hinged on the chair foot, and when the bracket rocker arm is shaken, the bracket is driven to lift, so that the seat plate is lifted; In addition, a lifting positioning device is arranged between the bracket and the chair foot.
