The invention provides a mechanical coded lock head. The mechanical coded lock head integrates a mechanical tumbler locking mechanism and a coded tumbler locking mechanism and has reliable performance and accurate coded positioning. The mechanical coded lock head is characterized in that the center of the lock head is provided with a lock cylinder, a code disk is arranged on the edge of the lock head, and marks are arranged beside the code disk; a back seat is sleeved outside the rear portion of the lock cylinder, one end of the back seat sleeve is close to the end surface of the lock head, and the other end of the back seat sleeve is connected with a spring bolt plate through a screw; the threads at the front end of the back main shaft of the code disk is threadedly arranged inside the screwed hole of the lock head and is limited through a snapping ring, the bar at the rear end of the main shaft is inserted into the axial hole of the lock head, and the rear end surface of the main shaft abuts against a tumbler which is arranged inside the axial hole of the back seat and pushed by a spring.
Description
technical field [0001] The invention relates to a combination lock head. Background technique [0002] The structural form of the existing mechanical tumbler lock has a history of nearly a hundred years, and it is very familiar and understood by people. There are endless ways to crack it, and there are many kinds of unlocking tools. The defects of this single locking structural form are the safety index and The amount of keys is low, and thieves can easily succeed in committing crimes. Robbery happens from time to time, and people feel a great threat to their safety. [0003] The operation of the electronic combination lock is too cumbersome, not suitable for young and old, and has poor interference ability and stability. [0004] The structure of the traditional combination lock head is complex, the failure rate is high, the code changing operation is very cumbersome, and the operation feels poor. Contents of the invention [0005] In view of the above problems, the pr...
