Description

Technical Field

[0002] Lockable gas spring, also known as self-locking gas spring or angle adjuster, is an industrial accessory with special functions. The lockable gas spring is filled with inert gas or oil-gas mixture in a sealed pressure cylinder to make the pressure in the cavity many times higher than the atmospheric pressure. The pressure difference caused by the cross-sectional area of ​​the piston rod being smaller than the cross-sectional area of ​​the piston is used to realize the movement of the piston rod. When locking is required, the internal valve is closed or opened by operating the release structure (such as pressing a small valve button or pushing the push rod), thereby locking or unlocking the piston rod.

[0003] Currently, most lockable gas spring releases on the market are divided into wire-controlled and lever-controlled types. Both types are opened manually and require a specific trigger force and trigger stroke to open the valve, with a low fault tolerance rate. In addition, the two release mechanisms require a large installation space, and special circumstances require a customized appearance, which increases the overall development cost.
