Abstract

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.

Description

A kind of safety lock structure

Technical field

The present invention relates to a kind of safety lock structure of pick-proof.

Background technology

It is antitheft that the cabinet (cabinet of such as ATM (Automatic Teller Machine) or safety cabinet) depositing valuables or banknote generally can install coded lock, but the pick-proof poor-performing of existing coded lock, when the lock core of coded lock destroys by lawless person outside cabinet, and make lock core from after lock comes off, illegal thief can push back to from locking station station of unblanking from outside by dead bolt, thus cabinet door is opened, steal the valuables in cabinet or banknote.

Summary of the invention

The object of the present invention is to provide a kind of can preventing by the safety lock structure prized.

Safety lock structure of the present invention, comprise the lock core be arranged on a body and the dead bolt matched with lock core, it is characterized in that: the position that door body is positioned at dead bolt rear is fixed with positioning seat, the front end face of positioning seat has the chute be retracted into for the rear portion of dead bolt when unblanking in it, the door body position be positioned between dead bolt and positioning seat is hinged with the positioning arm swung up and down, lock core is connected with the pressing plate on the sidewall of the free end of the positioning arm after can being pressed in the bottom, pressing plate is between surface and dead bolt in the part that dead bolt moves forward and backward scope, the hinge of positioning arm is set with torsion spring positioning arm being bestowed to the active force upwards swung, positioning seat is provided with the space upwards swung for positioning arm, when pressing plate with lock core destroyed drop after, torsion spring drives positioning arm upwards to swing and keeps off in chute front and stop that lock core retreats.

Safety lock structure of the present invention, the positioning arm that can swing up and down is hinged with in the door body position be positioned between dead bolt and positioning seat, and by the pressing plate be connected with lock core, the free end of the swing arm after the bottom is pushed down, when lock core is destroyed come off, positioning arm is depressed into the position be between door-plate and dead bolt by pressing plate all the time, can not affect the normal reverse of dead bolt when normally unblanking and move; And when illegal thief is from outside unauthorised broken lock core, and when causing lock core to come off from door body, pressing plate drops with lock core, now, and the free end no longer pressurized of positioning arm, it is under the elastic force effect of torsion spring, upwards be rocked to gear in chute front, and stop that dead bolt retreats, illegal thief still cannot push back to from locking station station of unblanking from outside by dead bolt, thus prevent the body from illegally being opened, prevent the valuables in cabinet or banknote stolen.

Detailed description of the invention

As shown in Figures 1 to 4, described safety lock structure, comprise the lock core 1 be arranged on a body 100 and the dead bolt 2 matched with lock core 1, dead bolt 2 can on door body 100 slide anteroposterior, the position that door body 100 is positioned at dead bolt rear is fixed with positioning seat 3, the front end face of positioning seat 3 has the chute 31 be retracted into for the rear portion of dead bolt 2 when unblanking in it, pressing plate 5 on the sidewall of the free end of the positioning arm 4 of door body 100 between dead bolt 2 and positioning seat 3 after the bottom, pressing plate 5 moves forward and backward scope part at dead bolt 2 is between a body 100 surface and dead bolt 2 on the direction perpendicular to door body 100 surface, when pressing plate 5 is pressed in the sidewall of the free end of the positioning arm 4 after the bottom, positioning arm 4 and pressing plate 5 all can not stop that the rear portion of dead bolt 2 retreats in chute 31, the hinge 41 of positioning arm 4 is set with the torsion spring 6 positioning arm 4 being bestowed to the active force upwards swung, positioning seat 3 is provided with the space 32 upwards swung for positioning arm 4, after pressing plate 5 drops with lock core 1 is destroyed, torsion spring 6 drives positioning arm 4 upwards to swing and keeps off in chute 31 front.When lock core 1 is destroyed come off, positioning arm 4 is depressed into the position being in door-plate 100 and is hinged with the positioning arm 4 that can swing up and down by pressing plate 5 all the time, lock core 1 is connected with the position can pressed between dead bolt 2, and the normal reverse that can not affect dead bolt 2 when normally unblanking moves (see Fig. 1, Fig. 2); And when illegal thief is from outside unauthorised broken lock core 1, and when causing lock core 1 to come off from door body 100, pressing plate 5 drops with lock core 1, now, the free end no longer pressurized of positioning arm 4, it is under the elastic force effect of torsion spring 6, upwards be rocked to gear in chute 31 front, and stop that dead bolt 2 retreats (see Fig. 3, Fig. 4), illegal thief still cannot push back to from locking station station of unblanking from outside by dead bolt 2, thus prevent the body from illegally being opened, prevent the valuables in cabinet or banknote stolen.

Locating part 8 is equipped with in the position of described door body 100 between the hinge 41 and pressing plate of positioning arm 4, positioning arm 4 after locating part 8 is provided with the confession bottom blocks screens 81 in the inner, to carry out spacing to positioning arm 4, pressing plate 5 can be pressed on the sidewall of the free end of positioning arm 4 better.

Described lock core 1 to be fixed on lock 7, and be arranged on a body 100 by lock 7, lock 7 has vertical storage tank 71, and the bottom of pressing plate 5 is pressed in storage tank 71 by lock core 1.
