[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1-4 , a cryopreservation box for cell experiments in this embodiment includes a cryopreservation box body 1 and a storage box 3 located inside the cryopreservation box body 1. The interior of the cryopreservation box body 1 adopts a dual refrigeration system, that is, the dual coiled pipe heat exchange method is used to refrigerate the inside of the cryopreservation box body 1 to ensure the refrigeration effect and the effective operation when a single refrigeration system fails.

[0024] In this embodiment, an outer door 2 for closing is hinged to the front of the cryopreservation box body 1. The interior of the cryopreservation box body 1 also has an inner door for heat insulation of the storage box 3 to increase the ambient temperature of the storage box 3.

[0025] It should be noted that a limiting frame 10 is fixedly installed inside the cryopreservation box body 1, and the storage box 3 slides relative to the limiting frame 10, so that the storage box 3 can be taken out of the cryopreservation box body 1 by pulling.

[0026] A handle block 4 is also fixedly installed on the outside of the storage box 3 in this embodiment, and the storage box 3 can be conveniently pulled through the handle block 4.

[0027] In this embodiment, there are several storage boxes 3 in a single layer on the limiting frame 10 to facilitate the classification storage of various samples. A partition structure is provided between the storage boxes 3 for connecting adjacent storage boxes 3 for use.

[0028] It should be noted that the partition structure includes a partition board 5 movably installed on the side of the storage box 3, and a groove 6 for the partition board 5 to be embedded is opened on the bottom wall of the storage box 3.

[0029] Preferably, the size of the groove 6 corresponds to half of the appearance of the partition board 5, and both the side edges of the partition board 5 and the groove 6 have continuously arranged tooth-shaped structures.

[0030] With such a design, on the one hand, it can strengthen the tightness of the partition board 5 embedded in the groove 6, and on the other hand, it can limit the partition board 5 from being relatively embedded in the groove formed by the combination of two grooves 6 to achieve the connection of two adjacent storage boxes 3.

[0031] In order to connect the partition plate 5 and the storage box 3, in this embodiment, arc-shaped sliding grooves 7 are provided on both sides of the inner wall of the storage box 3. A sliding block 8 is fixedly installed on one end of the partition plate 5 that fits against the storage box 3, and the sliding block 8 is slidably connected to the sliding groove 7.

[0032] Preferably, the sliding block 8 is located at a position offset from the horizontal end of the arc in the sliding groove 7, so that when the sliding block 8 rotates relative to the sliding groove 7, it will not rotate beyond the outside of the storage box 3 where the sliding groove 7 is opened.

[0033] In this embodiment, at the adjacent ends of the sliding grooves 7 on two adjacent storage boxes 3, a moving groove 9 is vertically communicated, and the sliding block 8 can also slide relative to the moving groove 9.

[0034] With such a design, after the sliding block 8 moves along the track of the sliding groove 7, it can continue to slide along the moving groove 9 until the partition plate 5 is inserted into the groove 6.

[0035] It should be noted that in this embodiment, a limiting groove 11 is also provided on the rear side wall of the storage box 3, and a baffle 12 that can extend into the storage box 3 to block the rotation of the partition plate 5 is slidably installed in the limiting groove 11.

[0036] In specific implementation, the baffle 12 can be toggled from above the storage box 3, so that the baffle 12 can slide and extend into the inside of the storage box 3 to block the partition plate 5.

[0037] The working principle of the above embodiment is as follows:

[0038] By pulling out the storage box 3 from the outside of the low-temperature storage box body 1, at this time, the sample can be placed in the storage box 3 and placed in the low-temperature storage box body 1. When classifying different types of widths of the single-layer structure, only need to pull out several consecutive adjacent storage boxes 3 to the outside of the low-temperature storage box body 1, and at the same time push the baffle 12 in the limiting groove 11 into the limiting groove 11. At this time, the partition plate 5 can be rotated relative to the storage box 3. When the partition plate 5 rotates, it can rotate relative to the sliding groove 7 through the sliding block 8 fixedly connected to its rear side to the position where the sliding groove 7 and the moving groove 9 are butted. At this time, the partition plate 5 completes a 90-degree rotation and changes from a vertical state to a horizontal state. Slide the sliding block 8 along the moving groove 9 towards the lower part of the storage box 3 until the partition plate 5 is inserted and fixed in the groove 6 below the storage box 3, so as to realize the position limitation between adjacent storage boxes 3 and remove the barrier, which is convenient for classifying the sample placement.
