Description

TECHNICAL FIELD

[0001] The present application relates to the field of safes, in particular to a pick-resistant bolt lock mechanism and a safe. BACKGROUND

[0002] With the continuous improvement of people's living standards and income levels, people have increasingly high requirements for the anti-theft function of safes. At present, although many innovations have been made on the basis of traditional experience, and in recent years there have been many good anti-theft mechanisms, including bolt lock pick-resistant mechanisms, but due to their internal structural defects, they cannot play a strictly pick-resistant role and do not have the function of preventing side impact damage. Because the traditional bolt lock is locked on the door frame (on the box) in the door opening direction (front and rear direction) and is not locked in the left and right directions, it relies only on the bending strength of the box itself to play an anti-theft role, so if an impact force is applied to the bolt lock on the side of the box, the bolt lock structure can be easily opened. SUMMARY

[0003] To solve the above problems, the present application proposes a safe pick-resistant bolt lock structure that solves the problem of the side of the safe being easily damaged by impact and opening the bolt lock structure.

[0004] The technical solution adopted by the present application is: a pick-resistant bolt lock mechanism, comprising a door panel, a mounting bracket is transversely and slidably connected to the door panel, a bolt block is fixedly arranged on the mounting bracket, a rotating bolt is rotatably connected to the outer end of the bolt block, and the cross-sectional shape of the bolt block and the rotating bolt is non-circular; a driving unit for driving the mounting bracket to slide is arranged on the door panel, and a transmission unit for driving the rotating bolt to rotate relative to the bolt block is also arranged on the door panel.

[0005] Through the above technical solution, the bolt block and the rotating bolt are used in cooperation with the door frame part or the box part, and the bolt block and the rotating bolt are rotatably connected in a non-circular shape. After the rotating bolt rotates relative to the bolt block, the part of the rotating bolt that exceeds the outline of the bolt block is clamped with the door frame part or the box part, which prevents the bolt block and the rotating bolt from retracting and sliding as a whole in the case where the rotating bolt does not rotate relative to the bolt block, increases the impact damage resistance of the bolt block and the rotating bolt in the retraction direction, and effectively increases the anti-theft capability.

[0006] Further, the plug is provided with an axle hole, the rotating bolt is provided with a rotating shaft, the rotating shaft is rotationally connected with the axle hole, and the rotating shaft is provided with a laterally extending side rod; the transmission unit comprises a connecting frame, a first driving shaft, a connecting disc and a first eccentric column, the connecting frame is vertically slidably connected with the mounting frame, the connecting frame is provided with a perforation for the side rod to extend into and adapt to, the first driving shaft is rotationally connected with the door plate, the connecting disc is fixedly connected to the first driving shaft, and the first eccentric column is eccentrically arranged on the connecting disc; and the connecting frame is laterally provided with a first strip-shaped hole for the first eccentric column to extend into.

[0007] Through the above technical scheme, when the first driving shaft rotates, the connecting frame is driven to slide up and down relative to the mounting frame through the cooperation of the first eccentric column and the first strip-shaped hole, and the rotation of the rotating bolt relative to the plug is realized through the cooperation of the perforation and the side rod. The user can realize the rotation of the rotating bolt relative to the plug by driving the first driving shaft to rotate, which is very convenient. The rotation of the first driving shaft can be controlled by combining the mechanical lock or the electronic lock, so that the mechanical lock or the electronic lock connected with the first driving shaft is kept in the state of clamping the part of the box or the door frame part beyond the profile range of the rotating bolt in the locked state, thereby increasing the safety.

[0008] Further, the mounting frame is provided with a strip-shaped limiting hole for the side rod to extend into, and the strip-shaped limiting hole is vertically arranged; when the side rod is rotated to abut against one end of the strip-shaped limiting hole, the cross-sectional profile of the rotating bolt and the cross-sectional profile of the plug are staggered with each other; and when the side rod is rotated to abut against the other end of the strip-shaped limiting hole, the cross-sectional profile of the rotating bolt and the cross-sectional profile of the plug coincide with each other.

[0009] Through the above technical scheme, the two ends of the strip-shaped limiting hole limit the range of the rotation angle of the side rod, so that the rotation angle of the rotating bolt relative to the plug is controlled within a reasonable range, the user is prevented from doing useless work, and the efficiency of controlling the rotation of the rotating bolt relative to the plug is improved.

[0013] Through the technical scheme, the user drives the second driving shaft to rotate, and the second eccentric column cooperates with the vertically arranged second strip-shaped hole, so that the mounting frame moves transversely and drives the rotating bolt and the block to move, and the user drives the second eccentric shaft to rotate, so that the rotating bolt and the block can be extended, which is very convenient to use.

[0015] Through the technical scheme, the setting of the block head increases the clamping point of the locking mechanism and the door frame part or the box part, increases the connection stability and the anti-picking safety, and in the process that the mounting frame slides transversely outward, the rotating disc is driven to rotate through the cooperation of the third strip-shaped hole and the shifting convex point, the rotating disc drives the transmission rod to push the block head to extend outward, and the block head, the rotating bolt and the block are extended or retracted at the same time, which is very convenient to use.

[0016] Further, the door plate is provided with a fixed rod, the rotating disc is rotatably connected to the fixed rod, a transversely waist-shaped hole is arranged on the mounting frame and used for the fixed rod to pass through, and the rotating disc is positioned between the mounting frame and the transmission rod.

[0017] Through the technical scheme, the rotating disc is limited between the surface of the mounting frame and the transmission rod, so that the connection of the rotating disc is more stable, and the transmission function between the rotating disc, the mounting frame and the transmission rod is ensured to be realized.

[0018] Further, the door plate is provided with an electromagnetic lock, the electromagnetic lock comprises a lock head, when the mounting frame slides outward to the limit distance, the lock head extends to abut and lock the mounting frame.

[0019] Through the technical scheme, after the lock head extends, the mounting frame can be locked, so that the block and the rotating bolt remain in the extended state, and if the electromagnetic lock is not unlocked, the rotating bolt and the block cannot be retracted, and the anti-picking performance is further improved.

[0048] The eccentric arrangement of the first eccentric column 11 specifically means that the axis of the first eccentric column 11 and the axis of the first driving shaft 9 are parallel to each other and are located on different straight lines in space.

[0049] Preferably, the length direction of the side rod 7 is perpendicular to the axis direction of the rotating shaft 6, so as to increase the efficiency of the side rod 7 driving the rotating shaft 6 to rotate.
