Description

Technical Field

[0001] This utility model relates to the field of cryopreservation devices, and in particular to a cryopreservation box. Background Technology

[0002] Cryopreservation boxes are standardized containers specifically designed for storing cryovials. Their interiors are typically composed of equally divided, independent compartments. This design not only ensures the orderly and stable placement of cryovials but also effectively prevents cross-contamination or confusion between different samples. For example, in cell bank management, each compartment can independently store a cryovial of a specific cell line, achieving physical isolation and clear labeling of samples.

[0003] In practical applications, cryovials come in a variety of sizes to meet different needs. However, the internal space design of existing cryovial boxes is relatively fixed, making it impossible to accommodate cryovials of different sizes simultaneously, which limits their use. Utility Model Content

[0004] The purpose of this invention is to provide a cryopreservation box with adjustable internal cryopreservation tube placement dimensions to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows:

[0006] This utility model discloses a cryopreservation box, including a box base and a box lid. The box lid is pivotally connected to the box base. The box base is provided with several limiting blocks and several limiting posts. The limiting posts are detachably connected to the limiting blocks. Cryopreservation tubes are placed between at least two limiting posts. When it is necessary to place cryopreservation tubes of different specifications, the limiting posts are removed and the limiting posts are installed on the corresponding limiting blocks, thereby realizing the size adjustment of the placement space, thus improving the flexibility of the cryopreservation box. It is convenient to adjust to the required size cryopreservation box when the corresponding size and specification of the cryopreservation box is not available, in order to cope with emergency situations.

[0007] The first option is that the limiting block is provided with an external thread and the limiting post is provided with an internal thread. The external thread and the internal thread are threaded together. Specifically, the number of thread turns can be set to 1.5 turns, so that it can be quickly opened or tightened.

[0008] The second option is as follows: the limiting block is provided with a plug-in hole, and the bottom of the limiting post is provided with a protruding edge. The protruding edge can be detachably installed in the plug-in hole. By inserting or pulling the protruding edge into the plug-in hole, a detachable connection can be achieved, which facilitates quick disassembly and installation.

[0009] Furthermore, to improve the stability of the limiting post in the second scheme, the inner wall of the insertion hole is provided with a rib, and the rib is held by the convex edge, thereby stabilizing the limiting post on the limiting block.

[0010] Since a cryopreservation box contains multiple cryopreservation tubes, when a corresponding cryopreservation tube needs to be removed, a grid with a numerical sequence is drawn on the surface of the box lid to remove the cryopreservation tube more quickly. However, since this cryopreservation box is adjustable, the grid markings need to be replaced. The specific solution is as follows: the box lid is provided with an installation slot and several grid cards, and the grid cards can be detachably installed in the installation slot.

[0011] After the cryopreservation box is placed in the ultra-low temperature freezer, it is sometimes difficult to remove the corresponding cryopreservation tube from the front of the box. The box base is also provided with a hollow hole, which is located on the side of the limiting block. That is, you can use your finger or pen to push the cryopreservation tube through the hollow hole at the bottom, so that you can remove the corresponding cryopreservation tube from the front.

[0012] Furthermore, the box base is provided with an air inlet, which is located at the bottom perimeter of the box base, so that cold air can enter the cryopreservation box through the air inlet during the storage process.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: It improves the existing slot-type cryopreservation box by designing the box base with several limiting blocks and several limiting posts. The limiting posts are detachably connected to the limiting blocks. When all the limiting posts are installed on the limiting blocks, it is the cryopreservation box size that can hold the smallest cryopreservation tubes. When some of the limiting posts are removed, some limiting blocks are not equipped with limiting posts, and the space between the four adjacent limiting posts becomes larger, thereby enabling the placement of larger cryopreservation tubes, improving the flexibility of the cryopreservation box, and also being able to cope with emergency situations where there are currently no cryopreservation boxes in use.

[0023] Example 1

[0024] Please refer to Figures 1-5 , Figure 6 and Figure 8 This utility model provides a cryopreservation box, including a box base 1 and a box cover 2. The box cover 2 is pivotally connected to the box base 1. The box base 1 is provided with several limiting blocks 11 and several limiting posts 12. The limiting posts 12 are detachably connected to the limiting blocks 11. Cryopreservation tubes are placed between four limiting posts 12. When it is necessary to place cryopreservation tubes of different specifications, the limiting posts 12 are removed and installed on the corresponding limiting blocks 11, so as to realize the size adjustment of the placement space, thereby improving the flexibility of the cryopreservation box and making it convenient to adjust to the required size cryopreservation box when the corresponding size and specification of the cryopreservation box is not available, so as to deal with emergency situations.

[0025] To design a 10*10 cryopreservation box, you can design it with 121 limiting blocks 11 and 121 limiting posts 12. When all the limiting posts 12 are installed on the limiting blocks 11, it is the smallest cryopreservation box size that can accommodate cryopreservation tubes, that is, the cryopreservation tubes are placed between four adjacent limiting blocks 11. When it is necessary to increase the placement space, some of the limiting posts 12 can be removed, and some limiting blocks 11 can be without limiting posts 12. The space between four adjacent limiting posts 12 becomes larger. Specifically, the cryopreservation tubes can be placed between nine adjacent limiting blocks 11.

[0026] It is worth noting that this utility model is not suitable for all sizes. Since the cryopreservation tubes need to be placed on at least two limiting posts 12, the size can only be increased by multiples of the minimum placement space. Therefore, the cryopreservation box of this utility model can only be limited to two sizes of cryopreservation tubes.

[0027] The limiting block 11 is provided with an external thread 111, and the limiting post 12 is provided with an internal thread 121. The external thread 111 and the internal thread 121 are threadedly engaged. Specifically, the number of thread turns can be set to 1.5 turns, so that it can be quickly opened or tightened.

[0028] Since a cryopreservation box contains multiple cryopreservation tubes, when a specific cryopreservation tube needs to be removed, a grid with numerical sequence is drawn on the surface of the box lid 2 to facilitate faster removal. However, because this cryopreservation box is adjustable, the grid markings need to be replaced. The specific solution is as follows: the box lid 2 has an installation slot 21 and several grid cards 3. The grid cards 3 are detachably installed within the installation slot 21. Specifically, the grid cards 3 are transparent, with only the dividing lines on the cards being white or black. After installation, stickers can be used to secure the edges of the grid cards 3 and extend them to the side of the installation slot 21.

[0029] After the cryopreservation box is placed in the ultra-low temperature freezer, it is sometimes difficult to take out the corresponding cryopreservation tube from the front of the box. The box base 1 is also provided with a hollow hole 13. The hollow hole 13 is located on the side of the limiting block 11, so that the cryopreservation tube can be pushed with a finger or pen through the hollow hole 13 at the bottom, so that the corresponding cryopreservation tube can be taken out from the front by hand.

[0030] Furthermore, the box base 1 is provided with an air inlet 14, which is located at the bottom perimeter of the box base 1, so that cold air can enter the cryopreservation box through the air inlet 14 during the storage process.

[0031] Example 2

[0032] Please refer to Figures 1-5 , Figure 7 and Figure 8 The second option is as follows: The limiting block 11 is provided with a plug hole 112, and the bottom of the limiting post 12 is provided with a protruding edge 122. The protruding edge 122 can be detachably installed in the plug hole 112. By inserting or pulling the protruding edge 122 into the plug hole 112, a detachable connection can be achieved, which facilitates quick disassembly and installation.

[0033] Furthermore, to improve the stability of the limiting post 12 in the second scheme, the inner wall of the insertion hole 112 is provided with a rib 1121, and the convex edge 122 holds the rib 1121, thereby stabilizing the limiting post 12 on the limiting block 11.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
