Safe lock structure
The invention discloses a safe lock structure. A positioning sway arm capable of vertically swaying is hinged to the position where a door body situates between a lock tongue and a positioning base, and a free end of the sway arm after downwards swaying is pressed through a pressing plate connected with a lock core; under the condition that the lock core is not damaged and dropped, the pressing plate always presses the positioning sway arm between the door plate and the lock tongue, and cannot influence the normal retreat and movement of the lock tongue during the normal locking; when illegal thieves damage the lock core illegally from the outside and consequently the lock core is dropped from the door body, the pressing plate is also fallen along with the lock core; at the moment, the free end of the positioning sway arm is not pressed any more; under the elastic function of a torsional spring, the positioning sway arm is upwards swayed to the front part of a chute and stops retreating of the lock tongue; illegal thieves still cannot externally push the lock tongue from the locking station to an unlocking station, so as to prevent the door body from being illegally opened, and prevent valuables or cashes in a cabinet from being stolen.
