Mechanism for locking and unlocking electronic safe lock barrel

摘要

A mechanism for locking and unlocking an electronic safe lock barrel which is provided with a retaining long key and is fastened with a rotary mechanism located on the outside of the safe door. The lock barrel has a portion which is located in the inside of the safe door and is provided with a position confining slide sleeve. The position confining slide sleeve is fastened at the rear end with a motor having a rotary shaft which is engaged with a threaded sleeve capable of displacing back and forth. The threaded sleeve is provided with a retaining slot for retaining the retaining long key of the lock barrel so as to prevent the lock barrel from being turned by the rotary mechanism. The motor is operated by the circuit to enable the threaded sleeve to retain or release the retaining long key of the lock barrel, thereby controlling the locking and the unlocking mechanisms of the electronic lock.
