The stopper shank 9 and the stopper tooth portion 10 of the stopper 6 are of a one-piece construction.
The unlocking key 5 of each set of key assembly 2 of the multi-key anti-theft door lock structure is set to be a structure with unlocking key tooth parts 8 with different length sizes, the blocking object tooth parts 10 of the blocking objects 6 of the multi-key assembly 2 are set to be structures with different length sizes, and the unlocking key tooth parts 8 and the blocking object tooth parts 10 of different key assemblies 2 are set to be structures with the same sum of the length sizes. By the structure, different keys can be matched with the door lock for use, so that different keys are formed.
When the multi-key anti-theft door lock structure needs to be unlocked, a set of key assembly comprising an unlocking key and a blocking object is used, and the blocking object tooth part of the blocking object of the key assembly is inserted into the key hole from the rear part of the key shell and is connected with the lock cylinder shell through a screw. When the door lock needs to be opened, the unlocking key tooth part of the unlocking key using the key assembly is inserted into the key hole, is matched with the blocking object tooth part and acts on the marble assembly. When partial marble of marble subassembly is used in the key tooth portion of unblanking and is unblanked key tooth portion cooperation and partial marble of marble subassembly is used in the jam thing tooth portion and blocks thing tooth portion cooperation, the key of unblanking sets up to realize the structure of many keys security door lock structure realization unblock that can rotate. After one key is lost, the blocking object arranged on the door lock is replaced, the blocking object of the other set of key assembly is replaced, and meanwhile, the key assembly is used for the unlocking key matched with the blocking object, so that the replaced key assembly is actually another key instead of only one key, and the same effect as the replacement of the door lock can be realized without replacing the door lock when the key is lost. Therefore, the problem of cost of replacing the door lock is solved, and safety is guaranteed. The multi-key anti-theft door lock structure is simple in structure and low in cost, and can achieve the effect equivalent to that of replacing a door lock by only replacing another set of key set price after a key is lost by dividing the key assembly into an unlocking key and a blocking object, so that potential safety hazards are solved, and the cost of replacing the door lock is avoided.
The present invention has been described in connection with the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments disclosed, but is intended to cover various modifications, changes and equivalents of the embodiments of the invention, and its application to other applications without departing from the spirit and scope of the invention.
