Description

Technical Field

[0001] The utility model relates to the technical field of gas springs, in particular to a gas spring with a safety locking structure. Background Art

[0002] A gas spring is a device that uses gas pressure to provide support and shock absorption. It is usually composed of a closed tubular container filled with compressed gas, such as nitrogen. When external pressure is applied, the gas is compressed, causing the spring to produce a reaction force. This reaction force can be used to support weight, reduce impact, or adjust the movement of the system. Gas springs are commonly used in various applications, including automotive suspension systems, industrial machinery, office chairs and other furniture, sports equipment, etc. Their advantages include light weight, small size, fast response speed, good adjustability, etc. In addition, gas springs can also adjust the air pressure as needed to change their support force and shock absorption effect, so they have high flexibility and adaptability in different application scenarios.

[0003] The patent document with publication number CN215293397U discloses an automatic protection type safety gas spring, including a piston rod, an outer sleeve, and a cylinder.
