[0009] a positioning screw with the lower end fixed on the heavy lock pin and the upper end extending out of the heavy lock box;

[0010] a pull rope with one end connected to the positioning screw, wherein the pull rope applies a pulling force in the direction opposite to the elastic force of the resilient member to prevent the longitudinal movement of the heavy lock pin;

[0011] The heavy lock plate is connected with the pull rope. When the heavy lock plate is damaged, the pull rope is released, the heavy lock pin moves longitudinally under the action of the elastic member, the head of the heavy lock pin extends out of the heavy lock box and abuts against the side wall of the sliding plate, so that the safe cabinet cannot be opened.

The pull rope is fixed on the lock through the heavy lock plate, so that the safe cabinet can trigger the heavy lock mechanism to lock when the door plate is attacked from the front and the lock hole is impacted, the tempered glass plate is damaged when the door plate is attacked from the front, the pull rope is released because the rope passing hole of the tempered glass plate no longer limits the pull rope, the pulling force of the pull rope on the positioning screw disappears, the heavy lock pin moves longitudinally under the action of the elastic member, the head of the heavy lock pin extends out of the heavy lock box, one of the heavy lock pins abuts against the edge of the side wall of the sliding plate, and the other heavy lock pin is inserted into the heavy lock hole arranged on the side wall of the sliding plate to relock the sliding plate; when the lock hole of the safe cabinet is impacted, the lock is detached, the pulled pull rope acts on the tempered glass plate to break the tempered glass plate, and the heavy lock mechanism can also be started to relock the sliding plate.

[0014] In order to further prevent the safe cabinet from being damaged, preferably, the accommodating space is further provided with a drill-proof plate between the heavy lock plate and the door plate. The drill-proof plate can prevent the drill from damaging the safe cabinet from the door plate of the safe cabinet, and enhance the anti-theft function of the safe cabinet. When the drill-proof plate is damaged, the drill can contact the drill-proof plate, and the heavy lock mechanism is effective.

[0015] Preferably, the heavy lock plate is a tempered glass plate. The tempered glass itself has a certain strength, which avoids the heavy lock mechanism from being effective due to collision during transportation, and can be completely broken to ensure that the heavy lock mechanism can be effective when the safe cabinet is severely damaged by external force.

[0016] In order to make the head of the heavy lock pin always have the tendency of extending out of the heavy lock box, preferably, the elastic member is a compression spring, the first end of the compression spring is fixed to the inner wall of the heavy lock box, and the second end is in contact with the tail of the heavy lock pin.

[0026] The utility model will be further described in detail below in combination with the embodiment of the drawings.

[0027] As Figures 1-6The safe cabinet anti-theft heavy lock structure of the embodiment comprises a sliding plate 2 capable of moving transversely relative to a door plate 1 of the safe cabinet and a lock 3 capable of blocking the transverse movement of the sliding plate 2, the sliding plate 2 and the lock 3 are conventional designs in the lock structure of the safe cabinet door, the transverse movement of the sliding plate 2 drives the extension and retraction of a latch head 8 connected with the sliding plate 2 to determine whether the safe cabinet door is locked or not, and meanwhile, the locking tongue 31 on the lock 3 extends to block the transverse movement of the sliding plate 2, so that the safe cabinet door is always in a locked state.

[0028] The improvement point of the embodiment is that a heavy lock mechanism 4 is arranged at each of the left and right ends of the lock 3, the heavy lock mechanism 4 comprises a heavy lock box 41, a heavy lock pin 42, an elastic member 43, a positioning screw 44, a pull rope 45 and a heavy lock plate 46. Figure 4 The heavy lock box 41 is arranged on the door plate 1, is located at the same side of the lock 3 as the sliding plate 2 and is arranged adjacent to the lock 3, the heavy lock box 41 is longitudinally provided with a strip-shaped hole 411. The heavy lock pin 42 and the elastic member 43 are arranged in the heavy lock box 41, the heavy lock box 41 is longitudinally movable relative to the door plate 1, so that the head 42a of the heavy lock pin 42 can extend out of the heavy lock box 41 and abut against the side wall 21 of the sliding plate 2 to block the transverse movement of the sliding plate 2, the elastic member 43 is a compression spring, the first end 43a of the compression spring is fixed to the inner wall of the heavy lock box 41, the second end 43b of the compression spring abuts against the tail 42b of the heavy lock pin 42 and can act on the heavy lock pin 42 to make the head 42a of the heavy lock pin 42 always have a tendency to extend out of the heavy lock box 41 and abut against the side wall 21 of the sliding plate 2. The lower end of the positioning screw 44 is fixed to the heavy lock pin 42, the upper end of the positioning screw 44 extends out of the heavy lock box 41 from the strip-shaped hole 411, the top of the positioning screw 44 is provided with a limiting portion 441 having a diameter greater than the width of the strip-shaped hole 411, and the limiting portion 441 is exposed outside the heavy lock box 41. The door plate 1 is provided with a mounting seat 5, the mounting seat 5 is provided with a mounting plate 51 arranged in parallel with the door plate 1, the lock 3 and the heavy lock mechanism 4 are arranged on the mounting plate 51, the mounting plate 51 is kept at a preset distance from the door plate 1, so that the mounting plate 51 and the door plate 1 form an accommodating space 6 therebetween, the heavy lock plate 46 is arranged in the accommodating space 6, the heavy lock plate 46 is provided with a rope passing hole 461, as shown in the figure, one end of the pull rope 45 is connected to the positioning screw 44, the other end of the pull rope 45 passes through the rope passing hole 461 and is fixed to the lock 3, and in this embodiment, the heavy lock plate 46 is a tempered glass plate. A pulling force opposite to the elastic force of the positioning screw 44 and the elastic member 43 is applied to prevent the longitudinal movement of the heavy lock pin 42 and make the heavy lock pin 42 be located at one end of the strip-shaped hole 411 close to the compression spring.

[0029] In addition, the accommodating space 6 is further provided with an anti-drilling plate 7, the anti-drilling plate 7 is located between the tempered glass plate and the door plate 1, and the arrangement of the anti-drilling plate 7 can prevent the drill from damaging the safe cabinet from the door plate 1 of the safe cabinet and enhance the anti-theft function of the safe cabinet.

[0030] As shown in the figure, Figures 2-3As shown, under normal conditions, the positioning screw 44 connected to the locking pin 42 is limited to the end of the strip hole 411 near the compression spring under the action of the pull rope 45. At this time, the head 42a of the locking pin 42 does not restrict the side wall 21 of the slide plate 2, and the slide plate 2 can move freely laterally when it is not locked by the lock 3.

[0031] In summary, the working principle and process of the anti-theft relocking structure of the security cabinet in this embodiment are as follows:

[0032] like Figures 5-6 As shown, when the safety cabinet is attacked from the front by the door panel 1, the tempered glass panel is broken. The pull rope 45 is released because it is no longer restricted by the rope hole 461 of the tempered glass panel. The tension of the pull rope 45 on the positioning screw 44 disappears. The relocking pin 42 moves longitudinally under the action of the elastic element 43. The head 42a of the relocking pin 42 extends out of the relocking box 41. One of the relocking pins 42 abuts against the edge of the side wall 21 of the slide plate 2, while the other relocking pin 42 is inserted into the relocking hole 22 provided on the side wall 21 of the slide plate 2, relocking the slide plate 2 and preventing the door panel 1 of the safety cabinet from being opened, thus protecting the safety of the safety cabinet.

[0033] When the lock hole of the safety cabinet is impacted, the lock 3 falls off, the taut pull rope 45 acts on the tempered glass plate, causing the tempered glass plate to break, and the relocking mechanism 4 is activated to relock the slide plate 2.
