Description

Technical Field

[0001] The utility model relates to the technical field of safes, in particular to a safe locking structure based on a mechanical code disk lock and an electronic lock. Background Art

[0002] Due to the rapid improvement of people's living standards, families have more and more cash and valuables, so the demand for safes or safes is also increasing. The safety door on the traditional safe is provided with a driving structure for driving the slide plate to slide, and at least one lock is provided to prevent the slide plate in the latching mechanism from sliding, so as to lock the door. The commonly used locks are electronic password locks, which have a control part input by a keyboard and a solenoid valve controlled by the aforementioned control part. When this electronic safe is working, first enter the password, and the iron core of the solenoid valve is retracted through the control part, and the slide plate is no longer prevented from moving backward, and then the safety door is opened by turning the handle. The disadvantage of this single electronic safe lock is that when there is a problem with the internal electronic components and the safe cannot be opened, it can only be opened by a special locksmith, which will delay the time of taking things out of the safe and is more likely to damage the safety door.

[0003] In summary, later safes or safe deposit boxes will be equipped with a mechanical emergency opening device on the door panel for opening the door body in an emergency. Among them, the emergency opening device and the electronic password lock usually use the same lock body. When there is a problem with the internal electronic components and the electronic password lock cannot be used to open the door body, the external emergency opening device lock body will be used to quickly open the door body. Since the lock body here adopts a two-in-one lock body, the lock body must be adapted to both mechanical and electronic opening methods. Therefore, the requirements for the lock body are relatively high, resulting in a complex lock body structure, high cost, and it is also easy to break and unstable.

[0004] In addition, since the control parts of such emergency opening devices are all exposed outside the door body, it is easy to make the door panel of the safe or safe appear messy as a whole and make the layout of the door panel front door appear not compact.

[0005] To this end, how to provide a safe locking structure with two split lock bodies to meet the two different door opening methods of electronic password opening and mechanical emergency opening, while at the same time making the control part of the emergency opening device not exposed, is a problem that technical personnel in this field urgently need to solve.
