Specifically, the cryopreservation tube 100 is used to store substances that need to be stored cold, such as cells.

[0044] like Figures 1 to 4 As shown, the carrier plate 1 is arranged at one end of the hollow bracket 2, and the carrier plate 1 is provided with a through hole corresponding to the hollow bracket 2 for inserting the cryotube 100; the sealing cover 3 is hinged to the carrier plate 1 and abuts against the carrier plate 1 to seal the port of the cryotube 100;

[0045] As in the above structure, when cells are frozen, the cells are placed in the cryopreservation tube 100, and then the cryopreservation tube 100 is inserted into the hollow bracket 2, and can be transported through the carrier plate 1 to achieve batch placement of the cryopreservation tube 100, while also reducing the risk of slippage and damage of the cryopreservation tube 100;

[0046] At the same time, since a sealing cover 3 is provided on the carrier plate 1, after the sealing cover 3 is fastened to the carrier plate 1, the port of the cryogenic tube 100 can be closed, thereby ensuring the hygiene inside the cryogenic tube 100 and avoiding contamination.

[0047] like Figure 4 As shown, the hollow bracket 2 includes two ring bodies 21 and a plurality of pillars 22, wherein the two ring bodies 21 are arranged opposite to each other, one of the ring bodies 21 is connected to the carrier plate 1; and both ends of the pillars 22 are connected to one ring body 21 respectively;

[0048] As in the above structure, after the cryotube 100 is inserted into the hollow bracket 2, it will be limited by the four pillars 22 to ensure good fixation. At the same time, the pillars 22 are used for temperature transfer, which can achieve slow cooling of the cryotube 100.

[0049] like Figure 4 As shown, the hollow bracket 2 further includes a buffer spring 23, which is disposed on the ring body 21 away from the carrier plate 1, and the buffer spring 23 faces the other ring body 21;

[0051] Specifically, the carrier plate 1 and the hollow bracket 2 are injection molded into an integrated structure, and the buffer spring 23 and the ring body 21 are an integrated structure. This can ensure the stability of the carrier plate 1 and the hollow bracket 2, and also improve the convenience of molding the hollow bracket 2.

[0052] like Figure 3 As shown, a plurality of hollow brackets 2 are provided, and the plurality of hollow brackets 2 are arranged in a row, and each row of hollow brackets 2 is connected by a connecting rod 4;
