Abstract
The utility model discloses an unlocking structure of a door lock. The unlocking structure comprises a lock shell, wherein a latch bolt and a dead bolt are arranged on one side of the lock shell in a sliding manner; a counter locking plate and an unlocking plate are arranged in the lock shell, the counter locking plate is arranged in the lock shell in an up-down sliding mode, and the counter locking plate slides to the rear portion of the dead bolt and can prevent the dead bolt from retracting into the lock shell; the lower end of the unlocking plate is rotationally arranged on the lock shell, the upper end of the unlocking plate is matched with the latch bolt, and the dead bolt is in linkage with the unlocking plate through a linkage piece. A lock cylinder rotating core connected with the lock cylinder is further rotationally arranged in the lock shell, and when the lock cylinder rotating core is rotated, a shifting block on one side of the lock cylinder rotating core pushes the counter lock plate to slide upwards, so that the counter lock plate is separated from the dead bolt; the shifting block continues to push the unlocking plate to rotate, so that the unlocking plate drives the dead bolt and the inclined bolt to retract into the lock shell through the linkage piece; a person outside a door can unlock the lock through a key and then push the unlocking plate to enable the dead bolt and the inclined bolt to retract into the lock shell, so that unlocking operation is achieved. In emergency, a person outside a door can unlock the lock through a key, and potential safety hazards are eliminated.
