Abstract

The invention discloses an intelligent lockset for an outdoor ring main unit. The lockset comprises a lock bracket (100) and a key (200). By identifying whether the key is authorized, opening and closing of a locking mechanism inside the lockset are realized. A solenoid is installed inside a cabinet door lock with the above function. In the locking state, the solenoid is inserted into a handle to block rotation of the handle, so as to block unlocking of the door lock. After the authorized key is inserted, the solenoid draws back to release locking of the handle. Then, the handle rotates to drive a gear to rotate, and a bolt also moves so as to open the door. However, when an unauthorized key is inserted, the solenoid is inserted inside the handle and the handle cannot rotate so as to block opening of the cabinet door. According to the invention, the severe potential safety hazard and malicious damage problems of a present outdoor ring main units' padlock mode are effectively solved.
