Electromagnetic anti-theft lock
Disclosed is an electromagnetic anti-theft lock. A thin cylinder is fixed to a left end of a key, the thin cylinder is mounted in a cylindrical housing, the cylindrical housing is fixed to a left end of a lock core, a button switch is mounted at a left end of a door lock, a button is connected with the thin cylinder in a touch manner, an upper electromagnet is fixed to the middle of an upper part of the door lock, an upper elastic hook is mounted below the upper electromagnet, a hook end of the upper elastic hook is inserted in an upper part of the lock core, a lower electromagnet is fixed to the middle of a lower part of the door lock, a lower elastic hook is mounted above the lower electromagnet, and a hook end of the lower elastic hook is inserted in a lower part of the lock core. According to the present invention, the upper elastic hook and the lower elastic hook are mounted on the lock core, so that the lock core can be hooked and cannot rotate, the upper elastic hook and the lower elastic hook are controlled by the upper electromagnet and the lower electromagnet respectively, coils of the electromagnets are connected with an alternating current of 220V through the button switch, the special thin cylinder is arranged at a top end of the key, and when the thin cylinder is pressed against the button, the switch is switched on, the electromagnets are powered and attract the upper elastic hook and the lower elastic hook, so that the upper elastic hook and the lower elastic hook are separated from the lock core; the key cannot unlock the door lock unless the lock core rotates, and therefore, the door lock can be prevented from being unlocked by a thief using a master key.
