Problems solved by technology
The elasticity of the spring is used to generate the reset force. The spring is easily deformed after a long time, so that the service life of the lock is not long; there is no lock shell on the lock cylinder, and the thief can insert the steel bar to open the lock cylinder, and it is easy to enter the rain and get rusty. Concealment effect is not good

The invention discloses an anti-theft door lock, comprising a lock case, a lock core and a lock bracket. A diminishing segment is provided at the back end of the lock core, and a fastener is positioned at the end of the diminishing segment. Correspondingly, the inner back end of the lock case is provided with an opening matched with the fastener which is capable of rotating in the opening. An iron pin is longitudinally installed and fixed in a vertical hole in the lock case, and is directly or indirectly contacted and cooperated with the fastener at the end of the diminishing segment of the lock core. The lock core is in the inner side and is not exposed, so that the lock is not easy to pry up, achieving better anti-theft effect and preventing rainwater from entering in the lock to cause rust. A locking mechanism is simple and firm. The production process is simple, and the lock is more practical and convenient.
