The gear unit of the door shock absorber includes a first spur gear coaxial with the pinion gear, a second spur gear engaged with the first spur gear, and a third spur gear engaged with the second spur gear and rotating the damper unit. Gear.
A ratchet gear portion formed in the pinion gear of the door shock absorber and a ratchet coupled to the first spur gear and selectively coupled to the ratchet gear portion by advancing and retracting the linear reciprocating unit.
The damper portion of the door shock absorber includes a speed increasing gear meshed with the gear unit, a magnet plate rotated by the speed increasing gear and including a permanent magnet, and a metal plate arranged to face the magnet plate and fixed to the case.
The magnet plate of the door shock absorber includes a first magnet plate and a second magnet plate facing each other, and the metal plate is fixed between the first and second magnet plates.
In the case of the door shock absorber, an escape portion is formed so that the pivoting piece and the case do not interfere with each other when the pivoting piece is pivoted.
The door shock absorber further includes a body mounted on a door frame of the door, an elevating rod ascending and descending within the body, and a resilient member including an elastic member for providing an elastic force to the elevating rod.
The door damper according to the present invention can be gently closed when the door in the opened state is closed to prevent damage to the body and noise and to reduce the size and improve the appearance by using a damper having a compact size and a large buffering force So that it can be mounted regardless of the opening direction of the door.
