The bottom plate 301 is assembled with the support plate 302 and the door frame 303. The door frame 303 is provided with the hinge 304, and the inner door plate 305 is movably assembled on the hinge 304.

[0025] In actual application, the low-temperature room shell 101 is provided with an independent storage cavity 102 inside. The two parallel surfaces of the inner cavity wall of the storage cavity 102 are both provided with a plurality of shelf support bars 103. The low-temperature room shell 101 is also assembled with the outer door plate 201, which is rotatably installed on the low-temperature room shell 101. The outer door plate 201 can seal the storage cavity 102 inside the low-temperature room shell 101 during rotation, thereby preventing the cooling air in the storage cavity 102 from overflowing. The storage cavity 102 is also assembled with the bottom plate 301, which supports the support plate 302. The support plate 302 is used to place the objects to be cooled, and one end of the support plate 302 is provided with the door frame 303. The inner door plate 305 is rotatably installed on the door frame 303 through the hinge 304. The bottom plate 301 and the cavity wall of the storage cavity 102 form an independent cavity, and the cavity is independently sealed and preserved by the inner door plate 305.

[0026] In one case of the embodiment, the door frame 303 is blow molded integrally, which can greatly reduce the assembly cost and bring obvious cost advantage to the product.
