An anti-disassembly hinge and a method for preventing disassembly of the hinge

Abstract

The invention relates to an anti-disassembly hinge. The anti-disassembly hinge comprises a hinge, internal blocks and sleeves, wherein the hinge is formed by hinging of two plates, and the internal blocks correspond to the plates. An insertion portion provided with a lock hole is arranged on each plate, and a slider with a lock pin is arranged on each internal block. Stop blocks, penetrating the plates to be inserted into the internal blocks and penetrate the sliders, are arranged on the internal blocks. Limiting sliding grooves are formed in the stop blocks. Retaining blocks located in the limiting sliding grooves are arranged on the plates, and are connected with the internal blocks through springs. A first connection rod and a second connection rod are arranged on each internal block, and one end of the first connection rod is hinged with one end of the second connection rod. The first connection rods are hinged with the sliders, and the second connection rods are connected with rotating shafts. Hexagonal splines are arranged at the ends of the rotating shafts. The internal blocks are provided with insertion holes matched with the hexagonal splines. The sleeves are matched withthe hexagonal splines, and clearance holes are formed in the plates. A hinge disassembly prevention method includes inserting the lock pins into the lock holes slidably through a triggering device andseparating the lock pins from the lock holes through a pulling device so as to achieve locking and unlocking between the plates and the internal blocks.

Description

technical field [0001] The invention relates to the technical field of door and window safety protection, in particular to an anti-disassembly hinge and a hinge anti-disassembly method.
