gas spring

A lockable gas spring(also known as a locking gas spring or hydraulic lock gas spring) is a special type of gas spring that allows the piston rod to be locked in any position along its stroke. This gives the user more control than a standard gas spring, which only provides pushing or lifting force.

As a key supporting component in the field of modern industry, the lockable gas spring can achieve stable locking at any stroke position through the synergy of internal pressure regulation and mechanical locking structure. Its technological development has promoted the innovation and upgrading of medical devices, automobile manufacturing, furniture design and other industries.

Lockable Gas Spring Structural principles and functional characteristics

The core structure of the lockable gas spring is composed of a sealing cylinder, a piston, a piston rod and a control valve body. The cylinder is filled with high-pressure nitrogen or oil-gas mixture, and the pressure difference is generated by the area difference on both sides of the piston to drive the piston rod to move. Its locking function relies on two mechanisms:

Elastic locking mechanism: the gas flow is controlled by adjusting the opening of the valve body to realize the flexible positioning of the piston rod within the stroke.

Rigid locking mechanism: using mechanical buckle and hydraulic damping double locking structure, locking force can reach more than 10000N. A typical application is a backrest adjustment system for a neurosurgical table, with an angle accuracy of ± 0.5 ° controlled by coated steel gas springs.

Key advantages of lockable gas spring

The"Genius" of the lockable gas spring is its clever combination of pressure regulation and mechanical construction:

Air pressure adjustment: through the internal high-pressure nitrogen or oil-gas mixture, lockable gas spring can provide different support according to the demand. For example, when you adjust the height of an office chair, the change in air pressure will make it easy for the chair to go up or down.

Mechanical locking: when a fixed position is required, the mechanical structure inside the lockable gas spring is activated immediately, acting as a"Lock" to lock the piston rod and prevent it from moving. This dual protection makes the air spring both flexible and reliable.

Although the lockable gas spring seems insignificant, but its existence makes our lives more convenient and safe. From medical devices to cars, from furniture design to industrial applications, lockable gas spring plays an indispensable role. In the future, with the continuous progress of technology, lockable gas spring will become more intelligent, more environmentally friendly, and bring more surprises to our lives.
