Abstract

The invention provides a multi-key anti-theft door lock structure applied to the technical field of door locks. A key hole (3) penetrating through a lock cylinder shell (1) is formed in the lock cylinder shell (1) of the multi-key anti-theft door lock structure; a marble assembly (4) is arranged in the lock cylinder shell (1); a plurality of marbles of the marble assembly (4) respectively extend into the key hole (3); a key assembly (2) comprises an unlocking key (5) and a stopper (6); the unlocking key (5) comprises an unlocking key handle (7) and an unlocking key tooth part (8); and the stopper (6) comprises a stopper handle (9) and a stopper tooth part (10). According to the multi-key anti-theft door lock structure, the key assembly can be divided into the unlocking key and the stopper,so that only another set of key assembly needs to be replaced after the key is lost; the effect equivalent to door lock replacement is achieved; the potential safety hazards are solved; and the doorlock replacement cost does not exist any more.

Description

technical field [0001] The invention belongs to the technical field of door locks, and more specifically relates to a multi-key anti-theft door lock structure. Background technique [0002] In people's daily life, there is often the problem of key loss. For safety reasons, most families either refit the locks or even choose to replace the door locks.
