The office swivel chair is a computer chair, a kind of office chair, a chair whose sitting part can rotate. The swivel chair can be divided into two types: half swivel chair and full swivel chair.
Usually consists of: headrest, back, seat, armrest, support rod (air rod), shaft, five claws, claw wheels.
The reason why the swivel chair can be raised and lowered is because there is a pneumatic rod in the lifting device. The pneumatic rod is an elastic element that uses gas and liquid as the working medium and can support, buffer, brake, height adjustment and angle adjustment. The basic principle is that the inside is filled with high-pressure nitrogen. Because there is a through hole inside the piston, the gas pressure at both ends of the piston is equal, but the cross-sectional area on both sides of the piston is different. One end is connected with a piston rod and the other end is not. , The pressure to the side with the smaller cross-sectional area is generated, that is, the elastic force of the pneumatic rod. When a person sits up and puts pressure on the lifting shaft, the lifting shaft will drop gently, the speed is uniform, and it can be reduced to the lowest point. No external force is applied to the lifting shaft, and the lifting shaft is raised back to the highest point.
