AI Technical Summary
Technical Problem
Traditional electromagnetic locks cannot be unlocked during power outages, preventing the safety cabinet door from opening properly and posing a safety hazard.
Method used
A mechanical lock drives the driven component to rotate, which in turn drives the transmission component to move the locking shaft and bolt of the electromagnetic lock, thus enabling unlocking even in the event of a power outage.
Benefits of technology
The safety cabinet can still be unlocked in the event of a power outage, avoiding the locked state caused by the electromagnetic lock not being powered on, thus ensuring the normal use of the safety cabinet.

Abstract
The utility model relates to the field of locks, and discloses a safety cabinet unlocking device which comprises a shell, a mechanical lock, a driven part, a transmission part and an electromagnetic lock, the shell is provided with a containing cavity, the mechanical lock is fixedly installed on the shell, the rotating end of the mechanical lock is located in the containing cavity, the driven part is fixedly installed at the rotating end of the mechanical lock, and the mechanical lock drives the driven part to rotate; the transmission part is rotationally installed in the containing cavity, the mechanical lock rotates to abut against the transmission part and drives the transmission part to rotate by a preset angle, the electromagnetic lock comprises a lock shaft and a spring bolt, the spring bolt is fixedly arranged at the end of the lock shaft, the lock shaft is in transmission connection with the transmission part, and the transmission part rotates to drive the lock shaft and the spring bolt to move in the preset direction. The mechanical lock drives the driven part to rotate, then the driven part drives the lock shaft and the spring bolt to move in the preset direction, and therefore the spring bolt is separated from the lock catch state, the unlocking function is achieved, and the function can be achieved through the mechanical lock in the power failure state.
