Description

Technical Field

[0001] This utility model relates to the field of damper technology, and in particular to an adjustable linear damper. Background Art

[0002] Traditional dampers are mostly radial rotation dampers designed to prevent high-speed rotation of workpieces. The few that can achieve axial damping are mostly achieved through pneumatic or hydraulic cylinders. However, these dampers are limited by the size and stroke of the cylinder, and cannot allow sliding workpieces to move without being restricted by stroke and direction.

[0003] The announcement number CN108905049B discloses an adjustable linear damper, including a slide rail, a sliding bearing sleeved on the slide rail, and a sleeve sleeved on the sliding bearing; end caps are fixed at both ends of the sleeve and the end caps are sleeved on the slide rail; one or more annular adjusting blocks and one or more annular damping plates of elastic material are arranged in sequence abutting each other in the inner cavity of the sleeve between the sliding bearing and the end cap.

[0004] When in use, the damper can only be adjusted by removing the end caps at both ends, and only the number of damping plates can be adjusted. The adjustment is inconvenient, and some workpieces need to frequently adjust the damping. However, the device is inconvenient to disassemble, resulting in low work efficiency. Therefore, we propose an adjustable linear damper. Utility Model Content
