Abstract

The invention relates to the related technical field of hardware fittings, and discloses a self-recovery buffer hinge. The hinge comprises two hinge main bodies, a movable frame is fixedly mounted onthe side wall of one hinge main body, and a fixed frame is fixedly mounted on the side wall of the other hinge main body. According to the hinge, a guide groove with the groove width gradually changing is formed in the side wall of the movable frame, meanwhile, a pressure collecting pipe is movably mounted on the inner wall of the movable frame, in the door opening process, the hole diameter between a pressure relief hole in the pressure collecting pipe and the guide groove is continuously reduced, then an extrusion pipe extrudes gas in a pressure collecting cavity, and thus the rotation rateof the movable frame is reduced, and the door opening speed is slowed down; and similarly, when a door is closed, negative pressure is generated in the pressure collecting cavity, so that the rotationrate of the movable frame is reduced, the phenomenon of violent impact in the opening and closing process is avoided, and finally the buffering effect is achieved.

Description

technical field [0001] The invention relates to the related technical field of hardware accessories, in particular to a self-restoring buffer hinge. Background technique [0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between them. Hinges are made of movable components or foldable materials, and are mainly installed on doors and windows. [0003] Existing household and hotel doors mainly use hinges to open and close the doors, and the working principle of the existing door hinges is mainly as follows: by fixing the hinge main body to the door and the door frame respectively, after that, a movable frame of the hinge main body The fixed frame of the other hinge body is movably connected through a pin shaft, so that the door has the function of opening and closing. [0004] However, in the actual use process, when the door is opened, the excessive force will cause the door to open and close faster, and the...
