Specifically, the four support vertical bars 1 are vertically arranged, and the four points formed on the horizontal plane constitute a square structure, and its length and width dimensions match the length and width dimensions of the freezing box. The support cross bars 2 are connected to two adjacent support vertical bars 1, and are arranged at intervals along the length direction of the support vertical bars 1, so that a plurality of cubic frames are formed on the freezing rack body, and their sizes match the stored freezing boxes, which are used to store freezing boxes.

[0029] Embodiment three:

[0030] See attached Figures 1 to 3 . On the basis of the second embodiment, the rotation blocking assembly includes a freezing box blocking body 7 and a positioning pin 8; the two ends of the freezing box blocking body 7 are rotatably connected to the upper top plate 3 and the lower top plate 4 respectively; the positioning pin 8 is provided with two, which are respectively connected to the upper end and the lower end of the freezing box blocking body 7. From the above structure, it can be known that the rotation blocking assembly includes a freezing box blocking body 7, which can be specifically a blocking bar, whose length covers the entire freezing rack body, and arc bars extend at both ends of the blocking bar, and are respectively connected to the upper top plate 3 and the lower top plate 4 at the ends of the arc bars, which can be hinged or connected by bearings to ensure that the blocking bar can rotate, and the blocking bar is connected to the same side of the upper top plate 3 and the lower top plate 4.
