Technical Field

[0001] The utility model relates to the technical field of cabinet locks, and more specifically to an intelligent lock for an outdoor cabinet. Background Art

[0002] Outdoor cabinets are widely used in the management of outdoor cabinet doors such as ring network cabinets and branch boxes in distribution networks. They can be used for the management of power supply marketing service meter boxes, agricultural distribution network meter boxes, and transformer cabinet doors. They can also be used for the safe management of a large number of on-site equipment in industries such as petroleum, chemical industry, and rail transit. Traditional outdoor cabinets use a metal cabinet body and cabinet door to protect the equipment.

[0003] Most of the existing outdoor cabinets use plum blossom cam locks. When opening the cabinet door, you only need to insert the key of the plum blossom lock into the lock body, and then rotate the cam at the rear end of the lock body 90 degrees to move the cam from the inside of the cabinet, so as to unlock the cabinet door. However, this type of cam lock has poor anti-theft effect and is easily opened by a copied key.
