Computer chair pressure bar lifting principle problem?
When the handle is matched, the lifting function of the chair can be realized. Gavee computer chair has instructions.
The reason is because the chair capable of lifting, the lifting device of a pressure rod, a pressure rod to gas and liquid as the working medium, the elastic element can support, buffer, brake, adjust the height and angle adjusting function, its basic principle is filled with high pressure nitrogen, because a through hole is arranged in the within the piston, piston ends equal gas pressure, and the cross-sectional area of the piston on both sides of the different end is connected with the piston rod and the other end is not, in under the gas pressure to one side of small cross-sectional area of the pressure, the pressure rod stretch, people sit up to the lifting shaft pressure, lifting shaft will fall gradually. Uniform speed, can be reduced to the lowest point. Do not lift the shaft outside, lift the shaft back to the highest point.
The gas spring can be stopped at any position in the stroke by means of a release device and has a large locking force after being stopped (up to 10000N or more).
