Abstract

Disclosed is a master-subordinate lock and master-subordinate key structure. A master-subordinate lock comprises a subordinate lock and a master lock, the subordinate lock is separated from the masterlock through a spring, the master lock is arranged in a master lock shell and provided with a USB interface which is connected with a single chip microcomputer, the single chip microcomputer is provided with a reading module and an output module, a decryption key is arranged in the reading module, the output module is connected with an electronic valve, and an attraction block of the electronic valve is a lock bolt of the master lock. A master-subordinate key is formed by splicing a front shell and a rear shell, a PCB is arranged inside the master-subordinate key and provided with a storage chip, an electronic key is stored in the storage chip, the front end of the master-subordinate key is provided with a USB port connected with the PCB, and the shells are provided with key teeth. An electronic master lock cylinder structure adopting a mechanical lock cylinder and USB unlocking is safer, burglar resistance is high, and maintenance is convenient; and moreover, the master-subordinate key adopts a combination of a mechanical key tooth structure and electronics, thereby being effectively prevented from being copied by other people and having a high safety coefficient.

Description

technical field [0001] The invention relates to a master lock and a master key structure thereof, and belongs to the technical field of IPC classification E05B. Background technique [0002] The development history of locks is very long. From the initial mechanical locks and mechanism locks to today's electronic locks, the development history of locks can be said to have progressed with the technology of theft. The level of theft prompts continuous reform and innovation of locks. [0003] At present, locks combined with electronic technology can be opened without a key, and can be opened only through mobile phones, fingerprints, passwords, etc., which can physically effectively prevent thieves from prying open the lock cylinder and prevent thieves from opening the lock. But these locks are often expensive because they don't use physical keys and require repairs if they go wrong or are electronically hacked. Contents of the invention [0004] The purpose of the present in...
