The invention discloses a buffering door closer. 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 installed 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 base, a first tension spring is arranged between the lower sliding plate and a bottom box, and the first tension spring pulls the lower sliding plate to always move in the direction deviating from the swing base; a second tension spring is arranged between the bottom shell and the swing base, and the second tension spring pulls the swing base to rotate towards the opening direction of the swing arm all the time; and a third tension spring and a buffer cylinder are arranged between the lower sliding plate and the upper sliding plate, and the third tension spring pulls the upper sliding plate and the lower sliding plate to move relatively all the time. 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 a door handle and other components do not need to be installed on a cabinet door, the cabinet body can be kept clean and attractive, potential safety hazards caused by collision betweenchildren and the handle are avoided, and the safety of the door closer is improved.
一种缓冲关门器，其包括底壳和面罩，底壳与面罩之间形成限位区，限位区内由下至上依次层叠安装有下滑板及上滑板，一摆臂通过摆动座与底壳上的铰接孔铰接，其中，所述的下滑板与底盒之间设置有第一拉簧，第一拉簧拉动下滑板始终向偏离摆动座方向运动；所述的底壳与摆动座之间设置有第二拉簧，第二拉簧拉动摆动座始终向摆臂打开方向转动；所述的下滑板与上滑板之间设置有第三拉簧及缓冲缸，第三拉簧拉动上滑板及下滑板始终向相对运动。本发明的有益效果是：本开门器与柜体安装后，可实现按压反弹式开启，因此柜门上无需安装门把手等部件，有利于保持柜体的整洁美观，避免儿童与把手发生磕碰造成的安全隐患，提升其安全性。
