Hydraulic door closer capable of damping during door closing
The invention relates to the technical field of door closers, and discloses a hydraulic door closer capable of damping during door closing. The hydraulic door closer comprises a door closer main body, a front piston, a front end cover, a first one-way valve, an oil groove, a main oil return hole, a secondary oil return hole, an auxiliary oil return hole, an oil storage cavity and an oil return cavity, movable cavities are formed in the positions, located on the two sides of the first one-way valve, of the interior of a front piston, compressed springs are fixedly connected to the bottoms of the movable cavities, and check blocks are fixedly connected with the lower parts of the top ends of the compressed springs. By designing the movable cavities, the compressed springs, the check blocks, a push rod, a sliding cavity and an air bag, when a door is closed, the front piston moves leftwards, when the remaining oil in an oil storage cavity is not enough to fill an oil groove, the push rod drives a baffle to extrude the air bag, so that air in the air bag is extruded into a through groove, the air bag is gradually shrunk to prevent the front piston from directly colliding with the front end cover, so that a door leaf and a door frame are prevented from directly colliding when the door closer realizes the door closing action, and the door leaf or the door frame is prevented from being damaged.
本发明涉及闭门器技术领域，且公开了一种关门减震的液压闭门器，包括闭门器主体、前活塞、前端盖、第一单向阀、油槽、主回油孔、次回油孔、辅回油孔、储油腔和回油腔，所述前活塞的内部位于第一单向阀的两侧开设有活动腔，所述活动腔的底部固定连接有压簧，所述压簧顶端的下部固定连接有挡块。本发明通过设计活动腔、压簧、挡块、推杆、滑腔和气囊，通过关门时前活塞左移，当储油腔内部的剩余油量不足以装满油槽时，通过推杆带动挡板挤压气囊，使得气囊内部的气体被挤压入通槽内部，并通过气囊的逐渐缩小避免前活塞直接与前端盖碰撞，从而避免在闭门器实现关门动作时造成门扇与门框的直接碰撞，防止门扇或门框之间造成损坏。
