When the rotating shaft is in motion, the rotating shaft protrusion pushes the damping slider downwards, compresses the spring, and the spring outputs thrust, which is transmitted to the rotating shaft through the damping slider< Br/> The thrust of the spring creates a rotational resistance on the rotating shaft, assisting in the gradual lowering or opening of the cover plate< Br/> This type of damper has rotation angle limitations and is generally used in conjunction with blade type dampers or linear dampers< Br/> Various types of cover plates are slowly lowered (washing machines, toilets, trash cans, etc.)< Br/>
