Abstract
The utility model discloses an anti-theft door lock. The anti-theft door lock can improve anti-theft safety performance of a door. A key hole (13) is formed in a door sheet (2) and communicated with a key cavity (4). A key hole baffle (3) is connected with the key cavity (4) which corresponds to a lock plate (6) provided with pins (5) and springs (7). The lock plate (6) is sequentially connected with a lock plate connecting lever (8), a handle connecting rod (14) and a handle (9), and is connected with a connecting rod (1), a spring bolt connecting lever (12), a spring bolt (10) and a door frame lock hole (11). When the door is opened, the pins (5) can not be contacted in the position of the key hole (13), and when the key hole baffle (3) seals the key hole (13), a key (17) can contact the pins (5) in the key cavity (4). The arrangement number of the pins is large, and therefore similar keys can not occur easily. The sealed key hole can prevent a master key and a similar key from opening the anti-theft door lock effectively, and therefore the safety anti-theft performance of the door lock is improved.
