Abstract

The invention relates to the technical field of hardware equipment, and discloses a pressure adjusting device of a door hinge self-closing mechanism and a door hinge comprising the pressure adjusting device. The door hinge comprises a fixed machine body and a movable machine body which are hinged, and the pressure adjusting device comprises a first sliding block, a second sliding block and a screw rod. The first sliding block is assembled in the movable machine body in a sliding mode and can slide in the telescopic direction of the self-closing mechanism, one end of the first sliding block is connected with the self-closing mechanism, and the other end of the first sliding block is provided with a first inclined surface; the second sliding block is assembled in the movable machine body in a sliding mode, the sliding direction of the second sliding block is perpendicular to the telescopic direction of the self-closing mechanism, and a second inclined surface connected with the first inclined surface in an abutting mode is arranged on the side face of the second sliding block. The screw rod is in threaded connection to the side wall of the movable machine body, and one end of the screw rod is rotationally connected with the end, away from the first sliding block, of the second sliding block. According to the door hinge with the pressure adjusting device, the pressure of the self-closing mechanism in the door hinge can be adjusted in real time, so that the door hinge can adapt to door bodies with different weights.

Description

technical field [0001] The invention relates to the technical field of door hardware equipment, in particular to a pressure regulating device for a door hinge self-closing mechanism and a door hinge including the same. Background technique [0002] At present, the doors of buildings such as shopping malls, residential quarters, office buildings, and meeting rooms are mostly doors that can be automatically closed. One of the realization methods of this type of door is to use a door hinge with a self-closing function. This kind of door hinge is provided with a self-closing mechanism inside, and the door hinge is driven to close by the resilience of the elastic member. [0003] The different thicknesses, materials, and shapes of the door body make the weight of the door body different, and then the external force required for closing the door is different. The rebound force provided by the above-mentioned self-closing mechanism is fixed. For a door body with a smaller mass, wh...
