Abstract

The invention belongs to the field of hardware fittings of doors and windows and provides a hinge. The hinge is used for being installed on a door and window leaf and a door and window frame. The hinge comprises a gear and rack unit and an inclined draw bar. The gear and rack unit is installed on the door and window frame. A gear is installed on the door and window frame in a rotatable mode. A rack is located on one side of the gear. The gear is meshed with the rack. A gear installation portion is arranged on one side of the gear. The two ends of the inclined draw bar are installed on the door and window leaf and the door and window frame respectively. The door and window leaf can be smoothly opened and closed on the door and window frame through the gear and rack unit on the premise that the number of hinge parts is reduced, and the gear and rack unit can form a force arm outside the gear installation portion. A part of the weight of the door and window frame is borne by the gear installation portion, most gravity of the door and window can be counteracted by the force arm formed by the gear and rack unit, and therefore most of the weight of the door and window is greatly shared; in this way, the problems that an existing hinge is unreasonably stressed and prone to damage are solved.

Description

[0001] technical field [0002] The invention belongs to the field of door and window hardware accessories, and in particular relates to a hinge.
