Embodiment Construction

[0008] A new type of anti-theft hinge, which is assembled from a three-tooth leaf 1, a two-tooth leaf 2, an end cover 3, and a mandrel 4, and is characterized in that a safety device buckle 5 is installed on the three-tooth leaf 1, Punch matching holes 6 at the positions corresponding to the two tooth sheets 2 and the safety device buckles 5, and the matching holes 6 and the safety device buckles 5 cooperate with each other. During installation, the three-tooth leaf 1 and the two-tooth leaf 2 are assembled, and the safety buckle 5 is installed on the three-tooth leaf, and the mandrel is strung in the common tube of the three-tooth leaf 1 and the two-tooth leaf 2, so that Connect, and finally embed the end cap 3 into the upper and lower parts of the pipe head. When the hinge of the present invention is closed, the safety buckle 5 on the three-tooth leaf 1 is inserted into the mating hole 6 of the two-tooth leaf 2, and as the mandrel 4 is completely drawn out, due to the coopera...

Abstract

The invention provides an anti-theft hinge, which is assembled by a three-tooth plate, a two-tooth plate, an end cover and a core shaft. In the invention, the three-tooth plate is additionally provided with a safety buckle; and the two-tooth plate is provided with a matched hole on the part corresponding to the safety buckle, and the matched hole is matched with the safety buckle. When the anti-theft hinge of the invention is closed, the safety buckle of the three-tooth plate is inserted in the matched hole of the two-tooth plate, if the core shaft is completely drawn out, because the safety buckle is matched with the matched hole, the three-tooth plate and the two-tooth plate can not be separated and moved, so that a door or window can not be removed, and the safety of the door or window is greatly improved.

Description

technical field [0001] The invention relates to a connecting piece between a door, a window and a frame, more specifically an anti-theft hinge. Background technique [0002] Most of the hinges currently on the market are assembled from two-toothed leaves, three-toothed leaves, mandrels, and end caps. After assembling the two-tooth leaf and the three-tooth leaf, string the mandrel into the shared pipe, and insert the end caps into both sides of the pipe through interference fit. During use, if the mandrel is taken out, the doors and windows can still be removed when the doors and windows are not opened, and there is a potential safety hazard. Contents of the invention [0003] Aiming at the defects of potential safety hazards in the existing hinge design, the present invention invents a new type of anti-theft hinge. reliability of use. [0004] The technical solution adopted by the present invention is: on the basis of the original structure, a safety buckle is added to ...
