Technical Field

[0001] The utility model relates to a main controller door lock mechanism, belonging to the technical field of door lock production. Background Art

[0002] The main controller needs to be installed in the corresponding cabinet body, and a lock is installed between the cabinet body and the cabinet door. Generally, a separate manual mechanical unlocking method is adopted for the lock, and the unlocking method is single. If a failure occurs, it cannot be unlocked in time, which is inconvenient to use.

[0003] The utility model with the patent number 202220546221.9 discloses a cabinet door electronic lock mechanism. It includes a mechanical lock, an electric control lock, a connecting device, and a locking attachment device. The mechanical lock, the electric control lock, and the connecting device are all installed on the cabinet door, and the locking attachment device is installed on the cabinet body. The mechanical lock and the electric control lock are separately arranged and are movably connected through the connecting device. The locking attachment device includes a lock catch and a support wheel. The lock catch is movably connected to the electric control lock, and the support wheel is arranged below the electric control lock. The mechanical lock drives the connecting device to touch the electric control lock, so that the electric control lock withdraws from the lock catch to unlock, or the electric control lock receives an electric control instruction in the vending machine and directly withdraws from the lock catch to unlock. The cabinet door electronic lock mechanism provided by the utility model is compatible with electric control unlocking and mechanical unlocking through the mechanical lock and the electric control lock, and has a low failure rate and is convenient for maintenance.
