Patent ID: 7325426

Claim:
A safe electromagnetic lock comprising: a case; a first keyhole disposed on the case; a second keyhole disposed on the case; a first bolt, outward extending from or retracting within a case, controlled by the first keyhole; an elastic fastener located at an end of the first bolt, the elastic fastener selectively abutting against a protruding edge of the case to disable the first bolt from arbitrarily retracting inward; an elastic slide block located within the case and slidably disposed on a bottom end of an extended section of the first bolt, wherein the second keyhole is configured to control a sliding movement of the elastic slide block on the bottom end of the extended section, thereby releasing an abutting state of the elastic fastener; an electromagnetic device positioned within the case at an upper end of the extended section of the first bolt, the electromagnetic device having an induction surface, the electromagnetic device being configured to enable the induction surface of the electromagnetic device to fittingly reciprocate the elastic fastener, the electromagnetic device being connected to a computer using conducting wires, wherein the electromagnetic device is activated to move and release the elastic fastener from abutting the protruding edge when a correct password is input into the computer; and a second bolt positioned within the case in a position above the first bolt, wherein, when locking the safe electromagnetic lock, the first bolt extends into a lockhole and the second bolt retracts within the case, wherein, when unlocking the safe electromagnetic lock, the first bolt retracts within the case and the second bolt extends out from the case, wherein the second bolt is freely retractable to prevent mistakenly locking the safe electromagnetic lock.
