Abstract

The invention relates to a door closer with door opening and closing bidirectional buffering and resetting functions. The door closer comprises a bottom shell and a face cover, wherein a limiting area is formed between the bottom shell and the face cover, a lower sliding plate and an upper sliding plate are sequentially mounted in the limiting area from bottom to top in a stacked mode, a swing arm is hinged to a hinge hole in the bottom shell through a swing seat, the swing arm rotates around the hinge hole, a first tension spring is arranged between the lower sliding plate and the bottom shell, a second tension spring is arranged between the bottom shell and the swing seat, and a lower baffle is arranged on the lower sliding plate. The door closer has the beneficial effects that after the door closer and a cabinet body are installed, pressing rebound type opening can be achieved, so that components such as a door handle do not need to be installed on a cabinet door, the cabinet body can be kept clean, tidy and attractive, potential safety hazards caused by collision between children and the handle are avoided, and the safety of the cabinet body is improved.

Description
