[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-7 This utility model provides a technical solution:

[0038] A modular cryopreservation rack includes:

[0039] The cryopreservation unit 1 includes a frame assembly 11 for storing sample boxes and a lifting assembly 12 located on top of the frame assembly 11 for lifting the frame assembly 11 out of the liquid nitrogen tank.

[0040] The support unit includes a front column 2 located at the front end of the frame assembly 11 and a rear column 3 located at the rear end of the frame assembly, which are used to cooperate with the front column 2 to clamp and limit the frame assembly 11.

[0041] It should be noted that by assembling the frame assembly 11 with the front column 2 and the rear column 3 in a snap-fit ​​manner, it is easy to assemble and disassemble the frame assembly 11 with the front column 2 and the rear column 3. When the spacing between the frame assemblies 11 needs to be adjusted to accommodate cryogenic boxes of different heights, it is only necessary to disassemble the frame assembly 11 of the corresponding area relative to the front column 2 and the rear column 3, adjust the spacing up and down, and then snap it back on. This method can accommodate cryogenic boxes of different heights and is easy to disassemble.

[0042] As an improvement, the frame assembly 11 includes:

[0043] Top plate 111, fastened to the top of the support unit;

[0044] The horizontal plate 112, provided in multiple sets, is clamped from top to bottom along the inner side of the support unit for storing the cryopreservation box;

[0045] The base plate 113 is fastened to the bottom of the support unit.

[0046] Furthermore, the top plate 111 is provided with a second upper buckle 1115 and a second upper plate 1116 on the front side of the top plate 111 to cooperate with the upper part of the front column 2, and a first upper buckle 1113 and a second upper plate 1116 on the rear side of the top plate 111 to cooperate with the upper part of the rear column 3.

[0047] The horizontal plate 112 has a second middle clamping plate 1123 that cooperates with the middle of the front column 2 on the front side, and a first middle clamping plate 1122 that cooperates with the middle of the rear column 3 on the rear side.

[0048] The base plate 113 is provided with a second lower buckle 1133 and a second lower plate 1134 on the front side to cooperate with the lower part of the front column 2, and a first lower buckle 1131 and a first lower plate 1132 on the rear side to cooperate with the lower part of the rear column 3.

[0049] Furthermore, the upper part of the front column 2 is provided with a second upper slot 22 and a first upper slot 21 for locking the second upper buckle 1115 and the second upper plate 1116, the middle part is provided with a first middle slot 23 for locking the second middle plate 1123, and the lower part is provided with a first lower slot 24 and a second lower slot 25 for locking the second lower buckle 1133 and the second lower plate 1134.

[0050] The upper part of the rear column 3 is provided with a third upper slot 31 and a fourth upper slot 32 for clamping the first upper buckle 1113 and the first upper plate 1114, the middle part is provided with a second middle slot 33 for clamping the first middle plate 1122, and the lower part is provided with a third lower slot 34 and a fourth lower slot 35 for clamping the first lower buckle 1131 and the first lower plate 1132.

[0051] As an improvement, the lifting assembly 12 includes:

[0052] Insert rod 121 is provided on the upper end of top plate 111. The upper end of top plate 111 is provided with a convex shell 1111 for tightening insert rod 121. The cross-section of insert rod 121 is square.

[0053] The handle 122 is fixedly connected to the upper end of the insertion rod 121 and is used to lift the insertion rod 121.

[0054] The fixing strip 123 is fixedly connected at one end to one side of the handle 122 and at the other end to the upper end of the insertion rod 121, and is used to reinforce the insertion rod 121 and the handle 122.

[0055] Furthermore, a first through hole 1112 is provided inside the top plate 111, and a baffle 114 is inserted into the first through hole 1112;

[0056] The baffle 114 extends from the top plate 111 downwards through multiple sets of horizontal plates 112, and is used to limit the movement of the horizontal plates 112;

[0057] The multiple sets of horizontal plates 112 are provided with a second through hole 1121 for accommodating the baffle 114.

[0058] It should be added that, in this utility model, the front column 2 and the rear column 3 are respectively provided in two sets, forming a square area that is compatible with the frame assembly 11, and the rear column 3 is bent at 90°.

[0059] It should also be noted that the first upper buckle 1113, the second upper buckle 1115, the first lower buckle 1131, and the second lower buckle 1133 in this utility model are made of tough materials, which facilitates the reset and locking of the top plate 111 and the bottom plate 113 after vertical insertion.

[0060] It should be noted that in the specific implementation of this utility model, the top plate 111 is vertically inserted into the upper part of the square area formed by the front column 2 and the rear column 3, so that the second upper buckle 1115 and the second upper plate 1116 are respectively fastened in the second upper slot 22 and the first upper slot 21, and the first upper buckle 1113 and the first upper plate 1114 are respectively fastened in the third upper slot 31 and the fourth upper slot 32. Then, the bottom plate 113 is vertically inserted into the lower part of the square area formed by the front column 2 and the rear column 3, so that the second lower buckle 1133 and the second lower plate 1134 are respectively fastened in the first lower slot 24 and the second lower slot 25, and the first lower buckle 1131 and the first lower plate 1132 are respectively fastened in the third lower slot 34 and the fourth lower slot 35, thus completing the splicing of the overall outer frame.

[0061] Subsequently, multiple horizontal plates 112 are inserted horizontally into the center of the square area formed by the front column 2 and the rear column 3, so that the first middle clamping plate 1122 and the second middle clamping plate 1123 are respectively clamped in the second middle clamping slot 33 and the first middle clamping slot 23, thus completing the assembly of the horizontal plates 112. When it is necessary to adjust the vertical spacing of the horizontal plates 112, simply pull out the horizontal plates 112 and reassemble them into the square area formed by the front column 2 and the rear column 3 at an appropriate spacing. This allows for the storage of cryogenic boxes of different heights. The main structure of the cryogenic rack is flexible and the disassembly process is simple.

[0062] After each assembly of multiple horizontal plates 112 and top plate 111 is completed, the baffle 114 is passed through the first through hole 1112 and multiple second through holes 1121 in sequence, so that the assembled multiple horizontal plates 112 can be further limited. At the same time, after the cryopreservation box is placed on the horizontal plate 112, the baffle 114 can also limit the cryopreservation box to prevent it from slipping.

[0063] In addition, the present invention bends the rear column 3 by 90°, which on the one hand improves the strength of the cryopreservation rack, and on the other hand prevents the cryopreservation box from sliding down the horizontal plate 112 on the side opposite to the baffle 114.
