Safes are companies, all walks of life and personal safes for depositing valuables and money. At present, there are products of multiple different structures, and no matter that kind of safes, they have their shortcomings. Some of these safes have complex structures, some are inconvenient to use, some are easily damaged, and the anti-theft performance is poor. There are 90% safe structures on the market that are easy to damage.

As shown in Figures 1 and 2, most of the safe locks on the market rely on the lock cylinder 9 arranged on the cabinet door 2 to drive the plectrum 4 to withstand the dead bolt 5 matched with the cabinet body 1 in the locked state. To prevent the safe from being opened, if the plectrum 4 withstands the dead bolt 5, the turntable 12 arranged on the cabinet door 2 cannot drive the dead bolt 5 arranged on the connecting rod 6 to move away from the cooperation with the cabinet body 1 by rotating the gear 7 At the same time, the connecting rod 6 cannot drive the lock tongue 5 on the upper and lower lock rods 8 and 11 to move and disengage through the cooperation of the pin 10 with the chute hole 601 on the upper lock rod 8 and the chute hole 1101 on the lower lock rod 11 respectively. With the state of cooperation with the cabinet body 1, the safe is in a locked state, otherwise, the safe can be opened by rotating the turntable 12. This kind of safe that adopts the plectrum structure often does not have a protective effect on the lock core 9. The lock core 9 is only fixed on the cabinet door 2 by a fixed plate 3, and a large part is exposed outside the cabinet door. During violent destruction, as long as the fixed plate 3 is slightly loose or falls directly, and the cooperation between the paddle 4 and the lock tongue 5 becomes loose or deviates, then as long as the turntable 12 is twisted, the safe door 2 will open naturally, and the entire safe will Lost the anti-theft function.

The safe locks with solenoid valves on the market use the rod of the solenoid valve to withstand the lock arm as the first layer of safety protection structure, but this structure is far away from the lock cylinder, which takes up too much space and is placed in other positions Sometimes, some places are the parts where the holes are installed for screws or the relatively fragile parts, which are easy to be drilled and directly stretched into the object to press the rod of the solenoid valve. In this way, the protective effect will also be invalid.
