[0030] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0031] Please refer to Figures 1 to 4 The embodiment is a reproductive medical embryo liquid nitrogen tank storage device, which comprises:

[0032] The liquid nitrogen tank 11 is fixed with a liquid inlet 12 on the upper surface, and an installation column 13 is fixed inside the liquid nitrogen tank 11.

[0033] The liquid inlet 12 is an inlet for injecting liquid nitrogen on the liquid nitrogen tank 11, is located at the top of the tank body, has a sealing cover valve, and keeps the sealing property of the tank body when not in use. The installation column 13 is used for supporting and fixing the lifting cylinder and the sample rack in the tank.

[0034] The heat preservation assembly comprises a fixing ring 21, a fixing frame 22, five arc-shaped grooves 23, five fixing shafts 24 and heat preservation cotton 25. The fixing ring 21 is fixed at the lower end of the outer surface of the liquid nitrogen tank 11. The fixing frame 22 is fixed on the upper surface of the fixing ring 21. The five arc-shaped grooves 23 are equidistantly arranged on the upper surface of the fixing ring 21. The five fixing shafts 24 are fixed in the corresponding arc-shaped grooves 23. The heat preservation cotton 25 is fixedly connected to the outer surface of the fixing shaft 24.

[0035] The fixing ring 21 is used for fixing the whole heat preservation assembly. The fixing frame 22 has an I-shaped structure, provides additional structural strength, and is provided with fixing holes 221 for cooperating with the clamping columns 29 on the fixing plate 26. The heat preservation cotton 25 covers the outer surface of the liquid nitrogen tank 11 to improve the heat preservation performance of the tank body.

[0036] Further, the fixing frame 22 has an I-shaped structure, and the upper end of the fixing frame 22 is provided with fixing holes 221 on both sides. The upper end of the heat preservation cotton 25 is fixed with a fixing plate 26. The fixing plate 26 is provided with mounting holes 27 on both sides. The first spring 28 is fixed in the mounting hole 27. One end of the first spring 28 is fixed with a clamping column 29, and the end of the clamping column 29 extends into the fixing hole 221.

[0037] The fixing plate 26 is provided with mounting holes 27 on both sides for mounting the first spring 28 and the clamping column 29. One end of the first spring 28 is fixed with a clamping column 29, and the end of the clamping column 29 extends into the fixing hole 221 for fixing the fixing plate 26 on the fixing frame 22.

[0038] Working principle:

[0039] When the medical embryo is placed in the liquid nitrogen tank 11, the liquid nitrogen tank 11 needs to be closed and stored, at this time the staff lifts the fixing plate 26, covers the heat preservation cotton 25 on the outer surface of the liquid nitrogen tank 11, and moves the fixing plate 26 in the two fixing frames 22, when the clamping column 29 is positively corresponding to the fixing hole 221, under the action of the elastic force of the spring, the first spring 28 will quickly restore the deformation, drive the clamping column 29 to move to both sides, make the both ends of the clamping column 29 clamp into the inside of the fixing hole 221, fix the fixing plate 26, and cover the heat preservation cotton 25 on the outer surface of the liquid nitrogen tank 11 at the same time;

[0040] In this step, the temperature environment in the liquid nitrogen tank 11 becomes more stable through the covering of the heat preservation cotton 25 and the fixing of the fixing plate 26. The heat preservation cotton 25 can effectively reduce the heat conduction through the wall of the liquid nitrogen tank 11, thereby reducing the evaporation speed of the liquid nitrogen and prolonging the use time of the liquid nitrogen.

[0041] Please refer to Figures 1 to 4 The embodiment is based on the above-mentioned embodiment, and further includes:

[0042] The placing assembly includes a fixing hook 31, a bottom plate 32, a placing barrel 33 and a through groove 331. The fixing hook 31 is hung on the upper surface of the mounting column 13. The bottom plate 32 is fixed on the lower surface of the fixing hook 31. The placing barrel 33 is fixed on the upper surface of the bottom plate 32. The through groove 331 is opened on the both sides of the outer surface of the placing barrel 33. The both sides of the outer surface of the placing barrel 33 are fixed with side connecting frames 34. The side connecting frames 34 are positively corresponding to the through grooves 331. The second springs 35 are fixed in the side connecting frames 34. One end of the second spring 35 is fixed with a clamping block 36. The clamping block 36 is slidingly installed in the through groove 331, and one side of the clamping block 36 extends into the inside of the placing barrel 33.

[0043] The fixing hook 31 is used for suspending the whole placing assembly in the liquid nitrogen tank 11. The placing barrel 33 is fixed on the upper surface of the bottom plate 32, which is the main part of directly accommodating and protecting the storage device. The second spring 35 is fixed in the side connecting frame 34, and one end is connected with the clamping block 36. When the storage device is placed into the placing barrel 33, the second spring 35 pushes the clamping block 36 through the elastic force, so as to automatically clamp the storage device, and ensure the stability of the storage device in the liquid nitrogen tank 11.

[0044] Working principle:

[0045] When the medical embryo is placed in the liquid nitrogen tank 11, the staff only needs to place the storage device into the placing barrel 33. Under the action of the elastic force of the spring, the second spring 35 drives the clamping block 36 to clamp the storage device from both sides and limit the storage device in the placing barrel 33, which reduces the steps of manual operation.

[0046] This step makes the whole placement process more convenient and fast, improves the work efficiency, especially in the environment which needs to frequently access samples.
