[0003] Patent CN209724110U discloses a mechanical anti-theft door frame and door leaf. At least one first bolt hole is opened on the inside of the four sides of the door frame; a door lock is arranged in the middle of the door leaf, and the door lock includes a rotating shaft, special-shaped gears and four linkages. The special-shaped gear is fixedly sleeved on the rotating shaft, and the rotating shaft is connected with the upper
skin and the lower
skin through bearings, and one end of the rotating shaft protrudes from the upper
skin, and the fixed sleeve is provided with a turntable for manual rotation; the special-shaped gear Including a disc, four wedge-shaped blocks are uniformly fixed on the outer
peripheral surface of the disc, the direction of the big end of the four wedge-shaped blocks is set in the same direction, and teeth are arranged on the outer surface of each wedge-shaped block; each linkage mechanism includes a sleeve, a second A gear, a return spring, a first connecting rod and a first door bolt, the sleeve is fixedly arranged on the lower skin, one end of the first connecting rod is rotationally connected with the first gear, the other end is fixedly connected with the first door bolt, and the sleeve is sleeved On the first connecting rod, one end of the return spring is connected to the corresponding first connecting rod, and the other end is connected to the sleeve. The first gear meshes with the
upper teeth on the outer surface of the corresponding wedge block; When the gear rotates, the wedge-shaped block drives the first gear to rotate, pushes the first connecting rod and the first latch to move linearly, inserts the first latches of the four linkage mechanisms into the corresponding first latch holes at the same time, and locks the door; reverse rotation The turntable, under the action of the return spring, pulls the first connecting rod and the first bolt to move backward, and the first bolts of the four linkage mechanisms are simultaneously disengaged from the corresponding first bolt hole to realize unlocking; the
disadvantage of this patent is that it uses manual Operation, the operation is laborious, and it is inconvenient to realize the
remote operation control switch, and it does not have intelligence
