The invention discloses a door closer which comprises a bottom shell and a face cover; a limiting area is formed between the bottom shell and the face cover; 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 groove-shaped reverse push plate is installed in the limiting area in a sliding mode; a driving plate is installed in the reverse push plate in a sliding mode; a first spring is arranged between the reverse push plate and the limiting area; a second spring is arranged between the reverse pushing plate and the driving plate; a guide wheel is arranged on the side, facing the swing seat, of the driving plate; and the guide wheel is in contact with the outer contour of the swing seat all the time under the action of the driving plate and presses the outer contour of the swing seat. The door closer has the beneficial effects that interaction surfaces between the driving plate and the swing seat are connected by the guide wheel, so that sliding connection is changed into rolling connection, friction between the driving plate and the swing seat is reduced while a basic function is realized, the work is more silent and stable, the wear is reduced, and the service life is prolonged.
一种闭门器，其包括底壳和面罩，底壳与面罩之间形成限位区，一摆臂通过摆动座与底壳上的铰接孔铰接，摆臂围绕着该铰接孔转动：其中，所述的限位区滑动式安装有呈槽状设置有反推板，反推板内滑动式安装有驱动板，所述的反推板与限位区之间设置有第一弹簧；所述的反推板与驱动板之间设置有第二弹簧，所述的驱动板朝向摆动座的一侧设置有导轮，导轮在驱动板的作用下始终与摆动座的外轮廓接触，并施压在该摆动座的外轮廓上。本发明的有益效果是：驱动板与摆动座之间的相互作用面采用导轮连接，因此将滑动连接改为滚动连接，在实现其基本功能的同时，降低两者之间的摩擦，使得其工作更加静音稳定，降低磨损并延长其使用寿命。
