AI Technical Summary
When a linear slide rail is in use, the slider may collide with a limit block or other objects when it moves quickly to the end of the guide rail, causing the slider or the object being collided with to break or be damaged, thus affecting normal use.
Before the slider contacts the fixed block, the movable block is pushed by inserting a push rod into the mounting groove, compressing the spring to buffer the impact force, and using the elasticity of the rubber pad and the spring to reduce the kinetic energy. At the same time, the rubber pad further buffers the impact force upon contact.
It effectively reduces the impact force between the slider and the fixed block, improves the service life of the guide rail structure, and avoids damage caused by collisions.
