Door closer with damping base plate structure

Abstract

The invention relates to the technical field of door closers, in particular to a door closer with a damping base plate structure. The door closer comprises a door closer main body, the inner side of the door closer main body is rotatably connected with a connecting shaft, the rear end of the connecting shaft is fixedly connected with a swing arm, the rear end of the swing arm is rotatably connected with a hydraulic rod, damping devices are fixedly connected to the bottom end of the door closer body and the bottom end of a first connecting base correspondingly, and the influence of vibration generated between a door plate and a door frame on the first connecting base and a second connecting base can be reduced under the action of rubber pads; meanwhile, under the interaction of a spring and a piston plate, the instant pulling force generated on the first connecting base and the second connecting base when the door plate is opened can be reduced, so that the vibration generated by the first connecting base and the second connecting base is further reduced, and a bolt cannot fall off due to vibration; and the speed of hydraulic oil passing through the piston plate can be adjusted under the action of an adjusting plate, and then the buffering force of the piston plate is adjusted.

Description

technical field [0001] The invention relates to the technical field of door closers, in particular to a door closer with a shock-absorbing substrate structure. Background technique [0002] The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It has the function of a spring door, which can ensure that the door is closed to the initial position accurately and in time after it is opened. , the modern hydraulic door closer (referred to as the door closer) began with a patent registered by the Americans in the early twentieth century. Function, the core of the design idea of ​​the hydraulic door closer is to realize the control of the door closing process, so that various functional indicators of the door closing process can be adjusted according to people's needs. With the development of society, the application of door closers is becoming more and more extensive, so , th...

Problems solved by technology

[0003] The connecting seat of the door closers currently used in the market needs to be connected with the door panel and the door frame by bolts. During the door panel opening and closing process, the impact between the door panel and the door frame will cause vibration. Long-term vibration will cause the bolts to loosen and fall off. , at the same time, the instantaneous pulling force generated by the door panel on the connecting seat of the door closer during the switching process will also cause the connecting seat to vibrate, and the phenomenon of bolt loosening is also prone to occur, and the existing door closer cannot adjust the degree of closure, and cannot To open a part of the door panel, therefore, a door closer with a shock-absorbing substrate structure is proposed to solve the above problems
