The novel door closer comprises a shell, a rotating shaft and a pressing block, a piston is axially arranged in the shell in a sliding mode, and an upper spiral face and a lower spiral face are arranged on the piston and the pressing block respectively; a protruding part is arranged between the rotating shaft and the pressing block through the piston, and when the rotating shaft drives the protruding part to rotate, the piston and the pressing block move up and down at the same time. A first sealing ring and a second sealing ring are arranged between the piston and the outer wall of the rotating shaft and between the piston and the inner wall of the shell respectively, and a reset elastic piece and an energy storage elastic piece are arranged between the piston and the end of the shell and between the pressing block and the end of the shell respectively. The piston or the rotating shaft or the shell is provided with an oil passing channel communicated with the upper oil cavity and the lower oil cavity, the oil passing channel is provided with a one-way valve, and the shell is filled with hydraulic oil. Or, a reset airtight chamber and an energy storage airtight chamber are arranged between the ends, opposite to each other, of the piston and the pressing block and the end of the shell respectively. The door closer has the advantages of being simple in structure, convenient to install and adjust speed, adjustable in buffering speed, long in service life and the like.
本发明涉及一种新型闭门器，包括壳体、转轴和压块，所述壳体内还轴向滑动设有活塞，活塞与压块上分别设有上螺旋面和下螺旋面；转轴经过活塞与压块之间设有凸起部，通过转轴带动凸起部旋转时，活塞和压块同时上下运动；活塞与转轴外壁之间、活塞与壳体内壁之间分别设有第一密封圈和第二密封圈，活塞和压块与壳体的端部之间分别设有复位弹性件和储能弹性件，活塞将壳体内部分隔有上油腔和下油腔，活塞或转轴或壳体设有连通上油腔和下油腔的过油通道，过油通道设有单向阀，壳体内灌注有液压油；或者，活塞和压块相互背对的一端与壳体的端部之间分别设有复位气密室和储能气密室；此款闭门器结构简单、具有安装、调速方便、缓冲速度可调、使用寿命长等优点。
