Technical Field

[0001] The utility model relates to the technical field of cell cryopreservation, in particular to a cell cryopreservation box. Background Technique

[0002] Cells are the basic units that make up organisms in biology. Cells are dynamic and determine our life states. In order to achieve the long-term storage of cells, the cell cryopreservation technology has emerged. Cell cryopreservation is to place cells in a low-temperature environment to reduce cell metabolism, so that cells can be temporarily separated from the growth state and their cell characteristics can be preserved. In this way, cells can be resuscitated for experiments and medical applications when needed.

[0003] Most of the existing cell cryopreservation boxes are composed of several test tubes inside. When moving, it is easy to shake and bump the tube body, which affects the cell storage state. At the same time, due to the small gap between the tube bodies of the test tubes, when using, it is necessary to take them from inside the cryopreservation box, which is easy to accidentally touch other test tubes and takes time. Therefore, those skilled in the art have provided a cell cryopreservation box to solve the problems raised in the above background technique. Summary of the Utility Model

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

[0023] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a cell cryopreservation box includes a box body 1, a bottom plate 18 provided at the bottom of the box body 1, a cryopreservation chamber 3 opened inside the box body 1, multiple groups of first clamping plates 6 provided in the cryopreservation chamber 3, and a second clamping plate 7 that cooperates with the first clamping plate 6. An extrusion linkage mechanism for driving their relative movement is installed on the first clamping plate 6 and the second clamping plate 7.

[0024] During use, the extrusion linkage mechanism includes a bidirectional motor 11 provided at the left ends of the first clamping plate 6 and the second clamping plate 7 and a connecting rod 15 at the right ends. Both the bidirectional motor 11 and the connecting rod 15 are installed on the support movable block 9. Both output ends of the bidirectional motor 11 are connected with threaded lead screws 12. Two groups of threaded lead screws 12 are threadedly sleeved with sliding members 14. Two groups of sliding members 14 are slidably sleeved on the connecting rod 15. The connecting rod 15 plays a role of support and fixation, so that the first clamping plate 6 and the second clamping plate 7 are kept flat and stable. The other ends of the sliding members 14 are fixedly connected with connecting blocks 13. The other ends of the connecting blocks 13 are respectively welded to the left and right end faces of the first clamping plate 6 and the second clamping plate 7. When the bidirectional motor 10 is started, the rotation directions of the two groups of threaded lead screws 12 are opposite, driving the sliding members 14 to move towards or close to each other, so that the first clamping plate 6 and the second clamping plate 7 are pushed by the connecting blocks 13 to move away and tighten, realizing the automatic clamping and scaling of the two groups of clamping plates, and no longer requiring manual operation to control the distance between the two groups of clamping plates. The operation is simple and the degree of automation is high.

[0025] In one embodiment, specifically, bumps 19 are provided at both the left and right ends of the first clamping plate 6 and the second clamping plate 7. The bumps 19 are slidably installed in the sliding grooves 20, and the sliding grooves 20 are dug on the inner side of the supporting movable block 9. A number of groups of semi-circular placement grooves are provided on the first clamping plate 6 and the second clamping plate 7. A clamping pad 8 is provided in each group of placement grooves. The clamping pad 8 is connected to the placement grooves on the first clamping plate 6 and the second clamping plate 7 by compression springs 21. When the freezing test tube is placed in the freezer, at this time, the freezing test tube is stored between the two clamping plates through the placement groove, and it is not completely fixed. It is easy to hit the wall during movement, resulting in the problem of breakage. Through the relative movement of the bumps 19 at both ends of the first clamping plate 6 and the second clamping plate 7 inside the sliding grooves 20, the two clamping plates are urged to clamp each other. At the same time, the clamping pad 8 connected by the compression spring 21 fixes the freezing test tube, avoiding the shaking of the test tube and achieving the protective effect. When the test tube needs to be taken out, the bidirectional motor 10 is started to make the bumps 19 move away from each other inside the sliding grooves 20, so as to realize the separation between the two clamping plates.

[0026] Specifically, a telescopic rod 10 is provided at the bottom of the supporting movable block 9, and the other end of the telescopic rod 10 is installed on the bottom plate 18. Through the setting of the telescopic rod 10, the first clamping plate 6 and the second clamping plate 7 are raised and lowered, which is convenient for taking and storing the test tube, and when freezing is required, it descends into the freezer 3 to improve the efficiency of cell cryopreservation.

[0027] Among them, an elastic pad 16 is provided on the bottom plate 18, and a number of groups of columnar movable members 17 are installed above the elastic pad 16. The movable members 17 can shrink into the elastic pad 16 to different depths according to different pressures to adapt to the bottom fixation of freezing test tubes with different diameters.

[0028] In one embodiment, specifically, the upper end of the box body 1 is movably connected with a cover plate 2. A lock catch 5 is fixedly installed on the cover plate 2. A lock catch 5 is provided on the contact surface between the cover plate 2 and the cover plate 2. The sealing ring 4 is located inside the cryopreservation chamber 3, which can effectively improve the tightness of the cell cryopreservation box and improve the quality of cell cryopreservation.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
