Abstract

The invention relates to an automatic lock. The automatic lock comprises an actuating plate, an inclined tongue, an anti-theft bolt, an abutting piece clamping bolt and a straight tongue. At ordinary times, the abutting piece clamping bolt on the anti-theft bolt supports the actuating plate, and if the anti-theft bolt is independently pushed at the moment, the abutting piece clamping bolt can not move due to the fact that the actuating plate abuts against the abutting piece clamping bolt. However, when the inclined tongue and the anti-theft bolt retract at the same time, the inclined tongue supports the actuating plate and pushes the actuating plate upwards, and then the abutting piece clamping bolt can move along with the anti-theft bolt and can not support the actuating plate for the moment. When the inclined tongue, the anti-theft bolt and the straight tongue correspond to a door frame and the inclined tongue and the anti-theft bolt are pushed into holes respectively, the actuating plate is pushed downwards at one moment due to the absence of the supporting of the inclined tongue and the abutting piece clamping bolt, and the straight tongue is directly pushed out into the door frame. In this way, the straight tongue can not be pushed out unless the inclined tongue and the anti-theft bolt reset, and then it can be guaranteed that the position of the straight tongue corresponds to that of a straight tongue hole of the door frame. Accordingly, locking is surely completed.
