Anti-theft door lock
The invention provides an anti-theft door lock which comprises a lock shell, and a main spring bolt, a main spring bolt connecting piece, a rack, a coupling gear and a rotating rod all mounted in thelock shell. The main spring bolt is fixedly arranged at the front end of the main spring bolt connecting piece. The main spring bolt connecting piece is connected with the rack, the rack is in transmission connection with the coupling gear, and the rack is driven by the coupling gear to move front and back and drives the main spring bolt connecting piece, the main spring bolt and the rack to movesynchronously. The rotating rod is coaxially connected with the coupling gear, a positioning column is arranged at the front end of the rotating rod, an inclined groove is formed in the main spring bolt connecting piece, the tail end of the inclined groove is bent to form an inflection point, and the positioning column is in sliding fit with the inclined groove in the inclined groove. During locking, the positioning column slides to fall into the inflection point to abut against and fasten the locking position, burglary prevention can be achieved, technical unlocking is prevented, and safety and stability are achieved.
本发明提出一种防盗门锁，包括锁壳和安装在锁壳内的主锁舌、主锁舌联片、齿条、联轴齿轮和转动杆。所述主锁舌固设在主锁舌联片前端；所述主锁舌联片与齿条连接，所述齿条与联轴齿轮传动连接，齿条受联轴齿轮驱动进行前后移动，且带动主锁舌联片及主锁舌与齿条同步移动。所述转动杆与所述联轴齿轮同轴连接，转动杆的前端设有定位柱，所述主锁舌联片上设有斜槽，所述斜槽的末端弯折形成拐点，所述定位柱于斜槽内与其滑动配合。上锁时，定位柱滑移至落入拐点处相抵紧固上锁位，可防盗、防止技术开锁，安全稳定。
