When the container containing fetal bovine serum is placed inside the box, it is convenient to place the container containing fetal bovine serum inside the box 1 in a regular and orderly manner;

[0037] Fetal bovine serum transport stage:

[0038] After the bracket 304 is placed in the box body 1, the cover plate 8 is rotated in the opposite direction by the third handle 17, and the support rod 13 is pulled to the right at the same time, the second spring 16 is compressed, and the cover plate 8 is fitted with the box body 1 through the rubber pad 11. The rubber pad 11 increases the sealing between the box body 1 and the cover plate 8. The support rod 13 is loosened, and the second spring 16 drives the second slider 12 to slide in the opposite direction under the elastic action. The second slider 12 drives the bent rod 14 to move, and the end of the bent rod 14 is stuck in the groove set in the box body 1. The cover plate 8 and the box body 1 are relatively closed. The box body 1 is fixed and placed on a transport vehicle for transportation. During transportation, the refrigerant 6 generates cold air, which contacts the test tube 10 through the third through hole 5 and the first through hole 305, thereby cooling and refrigerating the fetal bovine serum in the test tube 10 to achieve cold chain transportation. If bumps occur during the cold chain transportation of the fetal bovine serum, the rubber block 407 blocks the upper end of the test tube 10 to prevent the fetal bovine serum inside the test tube 10 from spilling out, so that the fetal bovine serum is not easily spilled out of the container during transportation.
