Abstract

The invention discloses a door hinge, which comprises: a fixed body, in which a first connecting shaft and a second connecting shaft are arranged along the lengthwise direction; a linkage assembly, whose two ends are respectively hinged with the fixed body and the motor body; the motor body, It is provided with a sliding block that can slide along the depth direction of the machine body. One end of the sliding block is hinged to one end of the linkage assembly. The track slope; the self-closing mechanism is arranged on the side of the motor body close to the straight surface of the track, and is a telescopic structure, one end of which abuts against the side of the sliding block, when the end of the self-closing mechanism abut When on the track slope, the sliding block is driven to slide to the inside of the engine body. The door hinge is a concealed hinge, and it also has the function of automatic closing.

Description

technical field [0001] The invention relates to the technical field of door hardware equipment, in particular to a concealed self-closing door hinge. 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.
