Description

Technical Field

[0001] The utility model relates to the technical field related to buffer blockers, in particular to an anti-stuck double-action buffer blocker. Background Art

[0002] A pneumatic damper is a device used to control and slow the movement of mechanical equipment. It is commonly used in industrial machinery systems that require precise stopping or deceleration. When the machine needs to stop or decelerate, the damper releases compressed air or gas into the damper's chamber, generating a damping force to slow the movement. The chamber is typically connected to a damping rod or piston. When a moving object contacts the damping rod or piston, the damping force is transmitted to the moving object, slowing or stopping its motion.

[0003] At present, most of the buffer stops on the market are single-acting, with only one air inlet, and rely on a spring to reset. Therefore, they are prone to jamming or even getting stuck during reset, which is not smooth enough. Utility Model Content

[0026] The support base 1 has a mounting groove 16 at its bottom, which is connected to the maintenance port via a sliding through hole. A magnet 15 is also embedded on the support base 1 .
