Safety relocking device of safe deposit box

Abstract

The invention discloses a safety relocking device of a safe deposit box; under an unlocking state, a primary lock pulling piece (8) swings downwards, a pressing limiting plate (10) shrinks, a knob (7)rotates in a positive direction and drives a machine plate (9) to slide in the positive direction; the mechanism plate (9) synchronously drives a side connecting plate (2) to slide and drives a circular disc assembly to rotate; under a locking state, the primary lock pulling piece (8) returns, the limiting plate (10) pops to abut against the mechanism plate (9); the knob (7) rotates reversely anddrives the mechanism plate (9) to reversely slide; and the mechanism plate (9) synchronously drives the side connecting plate (2) and the circular disc assembly to return. According to the device disclosed by the invention, a primary lock is damaged by collision while the safe deposit box is forced to damage by external force, and parts inside the safe deposit box also can be locked, so that a box door cannot be opened even the lock element of the primary lock is broken by collision. The safety relocking device is simple in structure, is low in manufacturing cost, is practical in function, and greatly improves safety performance of the safe deposit box.

Description

technical field [0001] The invention relates to the technical field of safes, in particular to a safe relocking device. Background technique [0002] The current safe relocking device includes a door panel, a side connecting plate connected with multiple side lock bars on the side, an upper connecting plate connected with the top lock bar, a lower connecting bar connected with the bottom lock bar, a main lock, and a main lock connected to the main lock bar. The main lock paddle on the lock, the upper connecting plate and the lower connecting rod are all connected with the disc assembly. When unlocking, the locking bars on multiple sides, the top locking bar and the bottom locking bar are all retracted into the door panel, so that the safe door can be opened. When locked, the locking levers on multiple sides, the top locking lever and the bottom locking lever all protrude to the frame of the cabinet, so that the safe door cannot be opened. [0003] The current safe / cabinet ...

Problems solved by technology

After the spare lock is knocked off and leaks out of the keyhole, the electromagnet is pressed down with the help of a steel wire. The main lock cylinder breaks due to the impact, and the main lock plate will fall off, unable to block the side connecting plate. At this time, the safety of the entire safe is greatly reduced. easy to open the box door
