[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides: an electronically controlled lock for cabinet doors, such as... Figures 1-4 As shown, the device includes a lock housing 1 and a latch 2. The lock housing 1 is installed on the cabinet body, and the latch 2 is installed on the cabinet door. The side of the lock housing 1 has a slot 3 for insertion. The latch 2 is inserted into the inside of the lock housing 1 in the slot 3. The lock housing 1 is used to be installed on the upper part of the cabinet body and cooperates with the latch 2 installed on the cabinet door 2 to lock the cabinet. The slot 3 is used for the latch 2 to enter the inside of the lock housing 1 for locking.

[0025] The lock housing 1 is equipped with an electric unlocking component 4 for unlocking in normal operation and a manual unlocking component 5 for unlocking during power outages. The electric unlocking component 4 and the manual unlocking component 5 work together. The electric unlocking component 4 inside the lock housing 1 is used to unlock the cabinet in normal operation, and the cabinet can be unlocked remotely, which is very convenient. The manual unlocking component 5 is used to unlock the cabinet when the electric unlocking component 4 cannot be used normally during power outages, ensuring that the cabinet can be used normally during power outages and guaranteeing the convenience of the cabinet.

[0026] As preferred, the electric unlocking assembly 4 comprises an electronic controller 41 installed inside the lock shell 1, an electromagnet 42 installed on the side of the electronic controller 41, a buckle 43 movably installed on the upper part of the electromagnet 42, an unlocking rod 44 movably installed on the middle part of the buckle 43, and the electronic controller 41 is used to control the movement of the whole electric unlocking assembly 4, and the electromagnet 42 is used to drive the buckle 43 to drive the unlocking rod 44 to move up and down, so that the unlocking piece 45 is separated from the lock piece 47, and the cabinet is unlocked by the electric control.

[0027] Further, one end of the unlocking rod 44 is fixedly installed with the unlocking piece 45, the inner wall of the lock shell 1 is fixedly installed with the first rotating rod 46, and the unlocking piece 45 is rotatably installed on the middle part of the first rotating rod 46. When the electromagnet 42 drives the unlocking rod 44 to move, the unlocking piece 45 will rotate on the first rotating rod 46 along with the unlocking rod 44, so as to be separated from the lock piece 47.

[0028] Further, the lower part of the unlocking piece 45 is clamped with the lock piece 47, the inner wall of the lock shell 1 is installed with the second rotating rod 48, and the lock piece 47 is rotatably installed on the middle part of the second rotating rod 48. When the unlocking piece 45 is separated from the lock piece 47, the cabinet door can be pulled to drive the lock catch 2 to move, and the unlocking piece 45 will rotate on the second rotating rod 48, so that the lock catch 2 can be separated from the inside of the lock shell 1, thereby realizing the electric opening of the cabinet door.
