Nov 21, 2018

The swivel chair is able to rise and fall because there is a pressure rod in the lifting device, the air pressure rod is a gas and liquid as the working medium, can be supported, cushioning, braking, height adjustment and angle adjustment and other functions of the elastic elements, the basic principle is that the internal charge of high-pressure nitrogen, due , and the cross-sectional area on both sides of the piston is different, one end is connected with the piston rod and the other end is not, under the action of gas pressure, the pressure on the side of the small cross-sectional area, that is, the elastic force of the air pressure rod, people sit on the lifting shaft pressure, the lifting shaft will drop gently, the speed Do not give the lifting shaft external force, lift shaft rise back to the highest point.
