Abstract

The invention discloses a door and window hinge, which comprises a first blade and a second blade which are axially connected to each other, and is characterized in that an anti-theft pin is fixedly arranged on the first blade, and an anti-theft hole corresponding to the anti-theft pin is arranged on the second blade; the advantage is that The structure is simple, and there are anti-theft pins and anti-theft holes on the first blade and the second blade of the hinge respectively. It is not easy to be sawn off or damaged, and can protect doors and windows from being disassembled, which is relatively safe and reliable; in addition, the first blade and the second blade are connected by two opposite upper pins and lower pins, so that the upper pin and the lower pin The pin shaft is not easy to be disassembled, and also has a certain insurance function.

Description

technical field [0001] The invention relates to a hinge, in particular to a door and window hinge. Background technique [0002] Many existing doors and windows are basically equipped with hinges. Through the hinge connection, the doors and windows can rotate freely without noise. It has anti-theft function and low safety factor, and the two blades of many hinges are only connected by a pin, so they are relatively easy to be disassembled. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a door and window hinge that is not easy to be dismantled and has good safety performance. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a door and window hinge, including a first leaf and a second leaf that are axially connected to each other, the first leaf is fixed with an anti-theft pin, and the second leaf An anti-theft hole corresponding to the anti-thef...
