Description

Combination locks for safes technical field The invention relates to a lock structure, in particular to a combined lock for a safe. Background technique At present, the unlocking methods of safes and safe deposit box series products manufactured by the safe industry are divided into two categories: electronic and mechanical. Electronics include fingerprints, passwords, and magnetic cards, and mechanical ones include keys and rotary passwords. The electronic opening method is to input the correct unlocking signal (such as fingerprint, password or magnetic card, etc.), the safety device (including electromagnet and motor) is energized to drive the valve tongue to shrink, and the door is opened by turning the handle to pull the lock bolt; mechanical opening The way is to pull the lock bolt to open the door by turning the lock cylinder (insert the key matching the lock cylinder or turn the dial according to the correct password to make the blade password slots consistent). ...

AI Technical Summary

Problems solved by technology

Among the various electronic locks mentioned above, due to the use of electronic components and power supplies, there must be failures and problems such as component failure, damage, and battery exhaustion. Therefore, electronic locks driven by electricity must be equipped with emergency door locks. In the technology, locks with keys are usually used as emergency door locks, such as the "Electromechanical Blade Lock" (CN1125226C) published by the Chinese Invention Patent. The security of the lock is higher than that of ordinary marble locks, but the key is still needed to open it, and there are problems such as easy loss or imitation of the key, and there are certain troubles in storage, which reduces the confidentiality and reliability of the safe; At the same time, blade locks and marbles are used as emergency door locks, and both have the possibility of being opened by technology, thereby reducing the safety of the safe
