The working principle of the gas spring is to fill the closed pressure cylinder with inert gas or oil and gas mixture, so that the pressure in the cavity is several times or tens of times higher than the atmospheric pressure, and the cross-sectional area of the piston rod is smaller than that of the piston to generate The pressure difference to achieve the movement of the piston rod. The support rod is an industrial accessory that can function as support, buffering, braking, height adjustment and angle adjustment. According to its characteristics and application fields, the support rod is also called gas spring, angle adjuster, gas pressure rod, damper, etc. According to the structure and function of gas springs, they are classified.
Gas springs include free-type gas springs, self-locking gas springs, traction gas springs, free-stop gas springs, swivel chair gas springs, gas pressure rods, and dampers. At present, the product is widely used in automobile, aviation, medical equipment, furniture, machinery manufacturing and other fields.
