DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-Figure 5 , which is the first embodiment of the utility model, provides an embodiment of a cell freezing box, including a box body 11, wherein a top cover 12 is fixedly disposed on the upper end surface of the box body 11;

[0026] The box body 11 is provided with an installation cavity 25, and two thermal insulation fixing plates 17 are fixedly provided on the lower wall of the installation cavity 25. The thermal insulation fixing plates 17 can play a role in isolating the temperature. A freezing working cavity 19 is provided on the lower end surface of the thermal insulation fixing plate 17, and six limiting frames 20 are fixed on the lower wall of the freezing working cavity 19. A test bottle storage cavity 18 connected up and down is provided in the thermal insulation fixing plate 17.

[0027] Six sealed top cavities 16 are arranged in the top cover 12 , and a rotating sealing frame 15 which can move up and down is arranged in the sealed top cavity 16 . The outer circumferential surface of the rotating sealing frame 15 is connected to the side wall of the sealed top cavity 16 by threads.

[0028] A sealing top block 24 is fixedly disposed on the lower end surface of the rotating sealing frame 15 , and the sealing top block 24 can perform compression sealing on the upper end surface of the test bottle.

[0029] The limiting frame 20 is provided with a spring chamber 21 therein.

[0030] The spring cavity 21 is provided with an elastic bottom block 23 which can move up and down.

[0031] An ejection spring 22 is fixedly connected between the lower wall of the spring cavity 21 and the lower end surface of the elastic bottom block 23 .

[0032] Two cold air external interfaces 13 are fixedly provided on the left and right walls of the freezing working chamber 19, and the cold air external interfaces 13 can be connected with an external refrigerator for ventilation.

[0033] A temperature detector 14 is fixedly disposed on the rear wall of the freezing working chamber 19 , and the temperature detector 14 can detect the temperature in the freezing working chamber 19 .

[0034] When it is necessary to freeze the cell test bottle, after opening the top cover 12, the test bottle is inserted into the corresponding test bottle storage cavity 18. After all the test bottles are completely in the corresponding test bottle storage cavity 18, the top cover 12 is closed. At this time, the lower end surface of the test bottle contacts the upper end surface of the elastic bottom block 23 and drives the elastic bottom block 23 to move downward, and the ejection spring 22 is squeezed, so that the upper end surface of the test bottle contacts the lower end surface of the sealing top block 24. At the same time, the cold air external interface 13 is connected to the freezing equipment or the box body 11 is placed inside an external freezing device. As the temperature in the freezing working cavity 19 gradually decreases, the test bottle will gradually freeze in the freezing working cavity 19 to complete the freezing of the test bottle.

[0035] After the test bottle is frozen, if a single test bottle needs to be taken out separately, the rotating sealing frame 15 above can be rotated to move the rotating sealing frame 15 and the sealing top block 24 upward until the rotating sealing frame 15 is completely taken out from the sealing top cavity 16, and the frozen test bottle in the test bottle storage cavity 18 on the same side will move upward into the sealing top cavity 16 under the influence of the rebound force of the ejection spring 22 and finally move to the upper side of the top cover 12. At this time, the staff can take out the frozen test bottle, and after taking it out, the rotating sealing frame 15 can be reinstalled to realize the work of taking out the test bottle separately. The utility model can greatly reduce the problem of thawing cells in other test bottles caused by the temperature difference caused by contact with the outside world when the test bottle is taken out, thereby improving the survival rate of cells, so that the utility model can have a better cell freezing and storage function.

[0036] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
