Problems solved by technology

However, the existing door closers usually use a rack and pinion or a hydraulic device to solve the problem of automatically closing the hinged door. For example, the patent CN201621120266.0 discloses a hydraulic door closer with electric assistance, in which the gear and the rack cooperate to drive The motor can drive the hinged door to close, but this kind of door closer will make the hinged door close faster, without cushioning, inconvenient to use and likely to cause safety hazards, and the rack and pinion is easy to fail, and does not have better smoothness

Abstract

The invention discloses a door closer. The door closer comprises a sleeve, an adjusting assembly, a first damping assembly and a second damping assembly; the first damping assembly and the second damping assembly are installed in the sleeve; the adjusting assembly comprises a first adjusting piece and a second adjusting piece; the first damping assembly comprises a first elastic piece; an end of the first elastic piece is connected to the surface of the first adjusting piece; the first adjusting piece is fixed to a rotating shaft; the first elastic piece can rotate around the rotating shaft; the second damping assembly comprises a damping piece; an end of the damping piece is hinged to the second adjusting piece; the second adjusting piece is fixed to the rotating shaft; and the damping piece and the first elastic piece can rotate around the rotating shaft at the same time. Through the adoption of the door closer, effective buffering can be provided, a rotating shaft door can be closed gently, the speed of different door opening and closing processes can be adjusted, and convenient use is achieved.

Description

technical field [0001] The invention relates to a switch with a braking device, in particular to a door closer. Background technique [0002] The traditional hinged door does not have a door closer and cannot close the door automatically. It requires the user to close the door manually. [0003] Existing hinged doors can be provided with door closers, and the door closers are used to automatically close the hinged door. However, the existing door closers usually use a rack and pinion or a hydraulic device to solve the problem of automatically closing the hinged door. For example, the patent CN201621120266.0 discloses a hydraulic door closer with electric assistance, in which the gear and the rack cooperate to drive The motor can drive the hinged door to close, but this kind of door closer will make the hinged door close faster, without cushioning, inconvenient to use and likely to cause safety hazards, and the rack and pinion is easy to fail, and does not have better smooth...
