Cells are highly sensitive to temperature and typically require a low-temperature, constant-temperature environment for storage. Chinese Patent Publication No. CN213840160U discloses a mobile stem cell storage device, including a cart with a base and legs. The legs have tracks, and a connecting rod is connected to casters and a braking device. The casters are positioned around the braking device. A limit block is provided on the connecting rod, and a groove is provided on the legs, with the limit block matching the groove. A first spring is located within the tracks, with one end connected to the legs. This mobile stem cell storage device includes a shock-absorbing device on the cart, and a first spring between the legs and connecting rod for shock absorption. An additional shock-absorbing device exists within the storage box. Through the matching of an auxiliary plate, guide column, and second spring, the storage rack has good stability, ensuring cell safety during movement. However, the above device has the following drawbacks in use: When placing or removing test tubes, the chamber needs to be kept open, which will cause the temperature inside the chamber to change, leading to denaturation of the remaining cells that are still being preserved. Utility Model Content

[0003] The technical problem this invention aims to solve is that when taking or placing test tubes, the chamber needs to be kept open, which can cause temperature fluctuations inside the chamber and affect other stored cells. To address this problem, a mobile cell storage device is proposed, comprising a storage chamber, a test tube rack, and a temperature control component. The test tube rack is snapped into the storage chamber, and the temperature control component is located inside the storage chamber. The bottom of the storage chamber is equipped with casters for easy movement. The test tube rack includes a frame body, a cover plate, a fixing plate, and a sliding plate. Multiple insertion holes for placing test tubes are provided in the middle of the upper surface of the frame body. The cover plate is hinged to the top edge of the frame body. The front and back sides of the frame body are continuous. The fixing plate is located on the upper part of the front and back sides of the frame body. The sliding plate is attached to the outer surface of the fixing plate and can slide vertically.

[0004] The technical solution of this utility model involves setting up a test tube rack that is snapped into the storage box. When taking out or placing test tubes, the test tube rack can be removed without keeping the storage box open, thus avoiding any impact on the cells in other test tube racks. The test tube rack, through the cooperation of a sliding plate and a fixed plate, can close the front and back sides of the frame body, and the top can be closed with a cover plate. After the test tube rack is removed, a closed space is formed, which can reduce heat exchange with the outside environment. After the test tube rack is placed into the storage box, the sliding plate slides upward, opening the lower part of the test tube rack, allowing the test tubes to exchange heat with the cold air inside the storage box, quickly maintaining the same temperature as the inside of the storage box.

[0005] In a preferred embodiment of the present invention, the storage box includes a storage cavity and an installation cavity, which are fitted together. Both the storage cavity and the installation cavity have lids on their tops. The lid of the storage cavity can be opened.

[0007] In a preferred embodiment of the present invention, a ring of protrusions is provided on the top edge of the frame body, and the raised upper surface is slightly higher than the top of the test tube. The protrusions are hinged to the cover plate, so the cover plate will not affect the test tube after it is covered. Furthermore, a sponge layer is provided on the surface of the cover plate that is in contact with the test tube to further improve the protection of the test tube.

[0008] In a preferred embodiment of the present invention, the outer surfaces of the two side walls of the main frame are provided with handles for easy picking, and the opposite surfaces of the two side walls of the main frame are provided with sliding grooves for easy sliding of the sliding plate. The handles facilitate picking up or placing the test tube rack, and the sliding grooves facilitate the movement of the sliding plate. When the sliding plate is at its lowest position, the lower part of the test tube rack is closed, which can maintain the temperature and allow the temperature to change slowly until it matches the ambient temperature. When the sliding plate is at its highest position, the lower part of the test tube rack is open, and the temperature can be quickly made to match the ambient temperature through heat transfer.

[0009] In a preferred embodiment of the present invention, the bottom of the frame body is provided with a positioning slot that cooperates with the positioning block. The positioning slot cooperates with the positioning block to achieve the snap-fit ​​of the test tube rack.

[0010] In a preferred embodiment of the present invention, a push block is provided on the outer surface of the sliding plate. The push block is located above the positioning slot. The positioning slot is aligned with the positioning block. Then, the test tube rack is lowered. At this time, the positioning block will fit with the push block, causing the sliding plate to slide upward. The bottom of the test tube rack is exposed, which facilitates rapid cooling of the test tubes and makes the temperature of the test tubes the same as that inside the storage box.

[0011] In a preferred embodiment of the present invention, a sponge pad is provided on the bottom upper surface of the frame body, and a recessed hole is provided on the surface of the sponge pad. The recessed hole is located directly below the insertion hole. The sponge pad is used to protect the test tube, and the recessed hole can position the test tube to prevent it from shifting or shaking.

[0012] In a preferred embodiment of the present invention, the temperature component includes a cooling element, a battery, a temperature sensor, and a display screen. The cooling element and the temperature sensor are disposed on the inner wall of the storage chamber, the battery is disposed in the mounting chamber, and the display screen is disposed on the cover of the mounting chamber. The cooling element, the temperature sensor, and the display screen are all electrically connected to the battery. The temperature sensor and the display screen are electrically connected. The cooling element is used to lower the temperature inside the storage chamber to facilitate the storage of test tubes. The temperature sensor is used to detect the actual temperature inside the storage chamber and display it on the display screen.

[0013] In a preferred embodiment of the present invention, the inner wall of the insertion hole is provided with protective sponge, and ventilation grooves are provided at intervals on the surface of the protective sponge that is in contact with the test tube. After the test tube rack is placed in the storage box, the cold air inside the storage box passes through the ventilation grooves and quickly cools the test tube, keeping the test tube within a suitable temperature range.

[0014] The advantages of this utility model compared with the prior art are: The technical solution of this utility model involves setting up a test tube rack that is snapped into the storage box. When taking out or placing test tubes, the test tube rack can be removed without keeping the storage box open, thus avoiding any impact on the cells in other test tube racks. The test tube rack, through the cooperation of a sliding plate and a fixed plate, can close the front and back sides of the frame body, and the top can be closed with a cover plate. After the test tube rack is removed, a closed space is formed, which can reduce heat exchange with the outside environment.

Detailed Implementation

[0016] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model will be described in detail below. Example 1

[0017] like Figure 1-6 As shown, this utility model is a cell preservation device that is easy to move, including a preservation box 1, a test tube rack 2 and a temperature component 4.

[0018] The inner cavity of the storage box 1 is divided by a partition to form two chambers, one of which is a storage chamber 11 and the other is an installation chamber 12. Both the storage chamber 11 and the installation chamber 12 are equipped with a box cover 13. The box cover 13 on the top of the installation chamber 12 is fixedly connected by bolts, and the box cover 13 on the top of the storage chamber 11 is hinged to the top of the partition. The box cover 13 can be opened to expose the storage chamber 11.

[0019] The storage box 1 is equipped with casters 14 at the four corners of the bottom. The casters 14 have a built-in braking function and are existing technology. The storage box 1 can be moved by the casters 14.

[0020] A push handle 16 is fixedly installed on the outer wall of the storage box 1. The push handle 16 is an integral structure with the storage box 1. The push handle 16 is preferably fixed on the outer wall of the mounting cavity 12. Through the push handle 16, it cooperates with the caster wheel 14 to facilitate pushing the storage box 1.

[0021] The temperature assembly 4 includes a refrigeration sheet 41, a battery 42, a temperature sensor 43 and a display screen 44, all of which are existing products. The refrigeration sheet 41 and the temperature sensor 43 are fixedly installed on the inner wall of the storage chamber 11, the battery 42 is fixedly arranged in the installation chamber 12, and the display screen 44 is fixedly arranged on the box cover 13 at the top of the installation chamber 12.

[0022] The refrigeration sheet 41, the temperature sensor 43 and the display screen 44 are all electrically connected to the battery 42, and are powered by the battery 42 for operation. The temperature sensor 43 is electrically connected to the display screen 44, and the temperature sensor 43 monitors the temperature inside the storage box 1 and displays the temperature through the display screen 44.

[0023] The battery 42 is a rechargeable storage battery, which facilitates moving the device at any time. Meanwhile, the power of the battery 42 can be displayed through the display screen 44, and the battery 42 needs to maintain sufficient power.

[0024] A plurality of positioning clamping blocks 15 are fixedly installed at the bottom of the storage chamber 11, and the positioning clamping blocks 15 are configured to clamp the test tube rack 2.

[0025] The test tube rack 2 includes a frame body 21, a cover plate 22, a fixing plate 25 and a sliding plate 26.

[0026] The cross-section of the frame body 21 is shaped like a Chinese character "kou".

[0027] A plurality of insertion holes 29 for placing test tubes 6 are defined at the middle position of the top of the frame body 21. After the test tubes 6 are inserted into the insertion holes 29, the top of the test tubes 6 is higher than the surface of the frame body 21, which facilitates taking the test tubes 6. The top edge of the frame body 21 protrudes upward to form a circle of convex blocks, the top ends of the test tubes 6 are slightly lower than the upper surface of the convex blocks, and the cover plate 22 is hinged to the convex blocks, so when the cover plate 22 is closed, the test tubes 6 cannot move upward.

[0028] A sponge layer is arranged on a surface of the cover plate 22 that fits with the test tubes. The sponge layer fits with the top of the test tubes 6 and can deform, so that the test tubes 6 are not easy to shake and will not be damaged by collision during transportation. A grip handle that is convenient for opening can be arranged on the surface of the cover plate 22.

[0029] Two side walls of the frame body 21 are solid, and a handle 23 that facilitates taking the device is respectively installed on the outer surface of each side wall. The handle 23 facilitates taking the test tube rack 2. Chutes 28 are formed by indentation on opposite faces of the two side walls, and the chutes 28 facilitate the sliding plate 26 to move up and down.

[0030] The front and back of the frame body 21 are empty. The fixing plate 25 is located on the upper part of the front and back surfaces of the frame body 21. The fixing plate 25 and the frame body 21 are an integral structure. The sliding plate 26 is slidably installed in the sliding groove 28. The sliding plate 26 is in contact with the fixing plate 25. When there is no external force, the sliding plate 26 falls naturally under the action of gravity and is in contact with the bottom of the frame body 21. At this time, the sliding plate 26 and the fixing plate 25 have an overlapping part, which closes the front and back surfaces of the frame body 21.

[0031] A push block 27 protrudes from the outer surface of the sliding plate 26. By applying external force to the push block 27, the sliding plate 26 can be driven upward and moved along the slide groove 28.

[0032] The bottom of the frame body 21 is a solid plate. Positioning slots 24 are opened on the front and rear edges of the bottom of the frame body 21. The positioning slots 24 match the positioning blocks 15. The positioning slots 24 can be inserted into the positioning blocks 15 to achieve the snap-fit ​​fixation of the test tube rack 2.

[0033] Furthermore, the push block 27 is located above the positioning slot 24. When in use, the positioning slot 24 is aligned with the positioning block 15. When the storage box 1 is placed from top to bottom, the push block 27 will fit against the positioning block 15. Then the sliding block 26 slides upward, exposing the bottom of the test tube rack 2, which facilitates rapid cooling of its interior. After being taken out, under the action of gravity, the sliding plate 26 naturally moves downward, sealing the test tube rack 2 and reducing heat exchange with the outside.

[0034] When the test tube rack 2 is placed into the storage box 1, the test tubes 6 placed inside it come into contact with the cold air inside the storage box 1, which can rapidly lower the temperature of the test tubes 6 until it is consistent with the temperature inside the storage box 1; when the test tube rack 2 is removed, the test tubes 6 placed inside it are isolated and do not easily exchange heat with the outside, thus maintaining a low temperature for a certain period of time.

[0035] A sponge pad 3 is glued and fixed to the bottom upper surface of the frame body 21. A recessed hole 31 is opened on the surface of the sponge pad 3. The recessed hole 31 is located directly below the insertion hole 29, and the shape of the recessed hole 31 matches the bottom shape of the test tube 6. Therefore, the test tube 6 is supported by the bottom through the recessed hole 31 and is not easy to shake.

[0036] The inner wall of the insertion hole 29 is bonded with protective sponge 5 to protect the side wall of the test tube 6.

[0037] The test tube 6 can be protected in all directions by the sponge pad 3, the protective sponge 5, and the sponge layer on the cover plate 22, avoiding damage from bumps and knocks.

[0038] Ventilation slots 51 are provided at intervals on the surface of the protective sponge 5 that is in contact with the test tube 6. When the test tube rack 2 is placed in the storage box 1, the ventilation slots 51 facilitate the circulation of cold air in the storage box 1, so that the temperature of the test tube 6 drops rapidly and remains uniform, and there will be no uneven cooling or local overheating.

[0039] The method of using a portable cell preservation device according to this embodiment is as follows: When test tube 6 needs to be used, open the lid 13 and take out the test tube rack 2 using the handles on both sides. Then close the lid 13 to avoid affecting other cells. After the test tube rack 2 is taken out, the sliding plate 22 slides downward under the influence of gravity. At this time, the test tube rack 2 is sealed, and the test tube 6 inside the test tube rack 2 is not in direct contact with the outside, which can reduce heat exchange and slow down the temperature change of the test tube 6. Then open the lid 22 and take out the test tube 6 that needs to be used one by one.

[0040] When test tubes 6 need to be placed, open the cover plate 22 of the test tube rack 2, expose the insertion hole 29, and then insert the test tubes 6 to be stored into the insertion hole 29 in sequence. Close the cover plate 22. Through the sponge layer, sponge pad layer 3 and protective sponge 5, the test tubes 6 cannot shake and are not easily bumped. Then, hold the handles 23 on both sides with both hands, align the positioning slot 24 with the positioning block 15, and insert the test tube rack 2 from top to bottom. During this process, the push block 27 gradually comes into contact with the upper surface of the positioning block 15, the sliding block 26 remains stationary, and the other structures of the test tube rack 2 continue to move downward until they come into contact with the bottom of the storage chamber 11. At this time, the test tubes 6 in the test tube rack 2 come into direct contact with the cold air inside the storage box 1, which can quickly cool the test tubes 6 until they are in the same temperature as the inside of the storage box 1, thus achieving cell storage.

[0041] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
