Background

A gas spring (gas spring) is an industrial accessory which can play the roles of supporting, buffering, braking, height adjusting, angle adjusting and the like. The principle is that inert gas or oil-gas mixture is filled in a closed pressure cylinder, the pressure in a cavity is several times or dozens of times higher than the atmospheric pressure, and the motion of a piston rod is realized by utilizing the pressure difference generated by the cross section area of the piston rod smaller than that of the piston. The gas spring has very obvious advantages over the common spring: the speed is relatively slow, the dynamic force change is not large, and the application is extremely wide, and the device is often used for supporting heavy objects.

Gas springs are typically in a compressed or semi-compressed state when installed on equipment and are compressed to a sufficient length when removed and installed.

At present, what the dismantlement mode of air spring still adopted in cigarette equipment is traditional dismouting method: the air spring is compressed to a sufficient length by manpower, and then taken out or installed. For gas springs with higher spring forces, stiffer springs, or longer lengths, it is often necessary for multiple people to work together to increase the pressure.
