[0004] The above-mentioned lockable handle for the refrigerator is used for locking. After the key is inserted into the lock panel, it is rotated and drives the lock core to cooperate. The rocker rod and the buckle are engaged to achieve locking or unlocking. The key needs to be carried to cooperate with it to unlock. It is inconvenient to use and needs to be improved. Summary of the invention

[0005] In order to improve the problem that a lockable handle needs to be used in conjunction with a key, the present technical solution provides a refrigerator door lock structure.

[0006] The purpose of this technical solution is achieved in this way:

[0007] A refrigerator door lock structure comprises a cabinet body and a cabinet door hinged to the cabinet body, the cabinet door is provided with a handle portion, the handle portion is provided with a mounting seat, the mounting seat is located below the handle portion, the mounting seat is provided with a mounting hole, a combination lock is installed in the mounting hole, the projection of the combination lock in the vertical direction is located within the projection of the handle portion, and the cabinet body is provided with a lock tongue cooperating with the combination lock.
