Main application range of gas spring

A gas spring is an elastic element that can function as support, buffer, braking, height adjustment and angle adjustment. The basic principle of the gas spring is to fill the airtight cylinder with nitrogen and oil with a certain pressure, or a mixture of oil and gas, and then use the pressure acting on the piston rod or piston section to make the gas spring generate thrust or pull.

The biggest difference between the gas spring and the mechanical spring is that the force-displacement curve of the former has a small slope, and the force value remains basically unchanged during the entire motion stroke, while the force-displacement curve of the latter has a large slope.

According to the structure and function of the gas spring, there are mainly free gas springs, self-locking gas springs, random stop gas springs, traction gas springs and dampers.

Gas Springs (compressed gas springs) only have two states of extension (the longest length without external force) and compression (the external force is greater than the thrust of the gas spring, and the length is the shortest). This type of gas spring has two structures of constant damping and variable damping. It is widely used in automobiles, construction machinery, textile machinery, printing machinery, office furniture and other industries.

Self-Locking Gas Springs (lifting lockable gas springs, angle-adjustable lockable gas springs) can lock the gas spring at any position of the stroke through its internal valve. According to different internal structures, this type of gas spring has elastic locking, compression Rigid locking, tensile rigid locking, compression and tension bidirectional rigid locking, etc. Self-locking gas springs have the functions of support, height and angle adjustment at the same time, and are convenient and flexible in operation and simple in structure. Therefore, they are widely used in medical equipment, furniture, automobiles, etc. industry is widely used.

Any Stop Gas Spring (balanced gas spring) can stop the gas spring at any position in the stroke through its special internal balance valve mechanism and reasonable external load design, but there is no additional locking force. Its characteristics are as follows: Between free-type gas springs and self-locking gas springs. Mainly used in kitchen furniture, medical equipment, electronic products and other industries.

Tension And Traction Gas Spring (extension gas spring) is a special gas spring: other gas springs are in the longest position when they are free, that is, they move from the longest position to the shortest position after receiving external force. , and the free state of the traction gas spring is in the shortest position, and it runs from the shortest to the longest when it is pulled.

The Damper can change the damping force with the movement speed through the damping structure on the piston, and can obviously damp the speed of the connected mechanism. This type of product has a variety of structures to suit different purposes. In automobiles, home appliances , medical equipment are used more.
