[0002] The mobile refrigerator includes a door body and a cabinet, and the door lock mechanism of the mobile refrigerator generally includes a lock hook and a pin shaft. The door body of the mobile refrigerator is locked or unlocked through cooperation of the lock hook and the pin shaft. In the related art, the pin shaft is generally installed on the cabinet through a mounting sheet. However, the mounting sheet is generally located between the cabinet and the door body and exposed to the outside, and the thickness of the mounting sheet is relatively thin. When the mobile refrigerator is used, the door is opened and closed frequently, which can easily deform the mounting sheet, and even cause the mounting sheet to separate from the cabinet shell and damage the door lock mechanism, thereby affecting the use reliability of the door lock mechanism of the mobile refrigerator. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a door lock mechanism and a mobile refrigerator, which can improve the use reliability of the door lock mechanism of the mobile refrigerator.

The cabinet is internally provided with a heat preservation space, and the heat preservation space is filled with foaming material. The door lock mechanism includes a lock hook assembly and a rotating shaft assembly. The lock hook assembly is arranged on the door body and includes a lock hook. The rotating shaft assembly is arranged on the cabinet and includes a pin shaft and a mounting sheet fixed with the pin shaft. Part of the pin shaft is exposed to the outer surface of the cabinet and is configured to limit cooperation with the lock hook to lock the door body or disengage from the lock hook to unlock the door body. The mounting sheet is located in the heat preservation space and at least partially covered by the foaming material.

[0005] By arranging the mounting sheet in the heat preservation space and at least partially covered by the foaming material, the foaming material can buffer and protect the mounting sheet, thereby strengthening the structural strength of the mounting sheet. In the process of frequently opening and closing the door body of the mobile refrigerator, the mounting sheet is not easy to deform and separate from the cabinet, thereby improving the use reliability of the door lock mechanism of the mobile refrigerator. In addition, the mounting sheet can be hidden in the heat preservation space, thereby improving the simplicity and aesthetics of the appearance of the mobile refrigerator.

[0006] In at least one embodiment, the pin shaft has opposite first and second ends. The first end penetrates the cabinet and is exposed to the outer surface of the cabinet. The second end is located in the heat preservation space. The rotating shaft assembly further includes a fixing piece. The fixing piece is located on one side of the mounting sheet and fixed with the second end. The fixing piece abuts against the mounting sheet to make the side of the mounting sheet away from the fixing piece tightly adhere to the inner surface of the cabinet.

[0008] In at least one embodiment, the second end of the pin shaft is wrapped by the foamed material.

[0009] The second end of the pin shaft is wrapped by the foamed material, and the foamed material wraps the pin shaft and the fixing piece in the thermal insulation space, thereby buffering and protecting the pin shaft and the fixing piece, improving the connection stability between the pin shaft and the box body, and preventing the pin shaft from shaking after being connected with the box body.

[0010] In at least one embodiment, the fixing piece has a through hole in the middle, and the second end is arranged in the through hole and connected with the fixing member.

[0011] The pin shaft is connected to the middle of the fixing piece, so that when the fixing piece is subjected to force applied by the pin shaft, the force applied to the fixing piece can be dispersed from the middle to the periphery of the fixing piece, thereby uniformly distributing the force applied to the fixing piece and reducing deformation of the fixing piece.

[0012] In at least one embodiment, the second end is threadedly connected with the fixing member.

[0013] The second end of the pin shaft is fixedly connected with the fixing member, thereby achieving detachable connection between the pin shaft and the fixing piece, and facilitating disassembly and assembly of the pin shaft, the fixing piece and the box body.

[0014] In at least one embodiment, the fixing piece is fixedly connected with the box body, and the pin shaft passes through the box body and is exposed to the box body.

[0015] The fixing piece is fixedly connected with the box body, thereby improving the connection stability between the shaft assembly and the box body, compared with the case where only the pin shaft is fixedly connected with the box body.
