Abstract
The utility model discloses an anti-theft lock with a special locking reinforcing function, comprising a lock housing, a lock catch box coordinating with the lock housing, a square bolt with one end extending out of the lock housing and the other end connected with an internal mechanism of the lock housing, a braking bolt and a self-touch pulley. When closing a door normally, a door frame touches the self-touch pulley to lock the square bolt automatically, and indoor and outdoor handles are rotated to open the door now; if the lock needs to be locked, the square bolt and the braking bolt are locked by using a key through one step, and the indoor and outdoor handles do not open the door. The lock with the structure can make users control whether the lock can be locked according to a locking need and has simple operation; a pulley in the lock catch box is pressed into a concave groove of the square bolt during locking to interlock or lock clockwise so as to achieve a tamper-resistant function, and therefore, the anti-theft effect is better.
