Door hinge with positioning buffer resistance and with automatic door closing function
A door hinge with positioning buffer resistance and with an automatic door closing function comprises a pair of hinge leaves. Hinge tubes of the hinge leaves are staggered to be in butt joint and then swing mutually around the same axis, a torsional restoration structure is arranged in the hinge tubes 11 of the hinge leaves, two adjacent ones of the hinge tubes of the hinge leaves sleeve an inner resistance sleeve and an outer resistance sleeve, and after the outer resistance sleeve sleeves the inner resistance sleeve, the exposed ends of the inner and outer resistance sleeves are fixedly connected with the corresponding hinge tubes where the inner and outer resistance sleeves are positioned. A sleeving space between the inner and outer resistance sleeves is filled with resistance oil or resistance grease, and accordingly, when the door hinge is mounted on a door and the opened door is driven to start to be closed by being driven by the torsional restoration structure, the door is closed slowly under the action of the resistance oil or the resistance grease in the inner and outer resistance sleeves, and pain of people in case that the people touch the door being closed can be relieved. Thus, the door hinge is more reasonable in structure and safer to use.
