Novel core pulling anti-theft disengaging hinge

Abstract

The invention provides a novel core pulling anti-theft disengaging hinge. The novel core pulling anti-theft disengaging hinge is composed of a three-tooth hinge piece and a two-tooth hinge piece, wherein one end of the three-tooth hinge piece is in interference fit with an end cover, a shaft core sleeves the pipe part of the two-tooth hinge piece, and a fastening screw is screwed up to complete installation; the two-tooth hinge piece can flexibly rotate in the core shaft, and the fastening screw is additionally arranged on the three-tooth hinge piece, so that the core shaft can be fixed, the shaft core is limited to move up and down, the hinge cannot be separated, and the safety of a door and window is improved; and the hinge is simple in structure, convenient to assemble and disassemble,and time-saving and labor-saving, the cost is greatly saved, the door and window can be directly detached without detaching the hinge under emergency situations, and the hinge is suitable for being used in emergency situations of fireproof doors and windows, and thus the production of an automatic assembly line is facilitated.

Description

technical field [0001] The invention relates to a connecting piece between a door and window and a door and window frame, more specifically a hinge that can be quickly and conveniently detached in an emergency and can be quickly installed, which is convenient, time-saving and labor-saving. Background technique [0002] At present, most hinges on the market are assembled by two-tooth leaf, three-tooth leaf, fixed mandrel, and end cover.
