The air duct 10 passes through the back of the box body 1 and is installed inside it, and an air outlet nozzle 11 is fixedly installed at the end of the air duct 10. A motor 4 is fixedly installed at the rear of the top of the box body 1, a placement plate 6 is provided inside the box body 1, a placement groove 12 is opened on the surface of the placement plate 6, and a screw rod 5 is provided at the rear of the surface of the placement plate 6, which passes through the placement plate 6 and extends to the bottom of the box body 1, and an auxiliary support plate 8 is fixedly connected to the bottom of the placement plate 6, and a telescopic support rod 7 is fixedly connected to the bottom of the auxiliary support plate 8, and the length of the auxiliary support plate 8 is approximately the same as the length of the placement plate 6.

[0027] In this embodiment, a return spring 13 is fixedly connected to the inner wall of the placement groove 12, and an arc-shaped fixing plate 14 is fixedly connected to the end of the return spring 13. The arc-shaped fixing plate 14 can be set to fix and clamp the test tube to prevent the test tube from accidentally falling off when people carry the box 1 and causing damage. At the same time, shaking can also be avoided during the lifting and lowering of the placement plate 6.

[0028] In this embodiment, an anti-skid pad is bonded to the surface of the arc-shaped fixing plate 14. The anti-skid pad is made of rubber material. The provision of the anti-skid pad increases the contact friction between the arc-shaped fixing plate 14 and the test tube, which helps to improve the fixing effect.

[0031] Embodiment 2:

[0032] On the basis of Example 1, a preferred embodiment of the auxiliary cooling CART cell filling and storage device provided by the utility model is as follows: Figures 1 to 4 As shown:

[0033] In this embodiment, a temperature and humidity detector is fixedly installed at the upper part of the interior of the box body 1, and a display component is provided on the front of the box door 2. The temperature and humidity detector is electrically connected to the display component.

The telescopic support rod 7 and the auxiliary support plate 8 can make the placement plate 6 more stable when lifting and lowering. Since the test tube is clamped and fixed by the arc-shaped fixing plate 14, the influence of the tiny shaking force generated during the lifting process on the test tube is effectively reduced. The setting of the sealing layer 3 and the thermal insulation layer 15 can keep the cold air inside the box 1 warm and reduce the loss of cold air.

[0037] In summary, with the aid of the above-mentioned technical scheme of the utility model, through the arranged screw rod 5, the placement plate 6 is moved up and down under the drive of the motor 4, and is in close contact with the air outlet nozzle 11, thereby accelerating the cooling speed of the cells in the test tube and reducing the time required for the cooling step. The telescopic support rod 7 and the auxiliary support plate 8 can make the placement plate 6 move more smoothly when it is raised and lowered. The arc-shaped fixing plate 14 can fix and clamp the test tube to prevent the test tube from accidentally falling off when people carry the box 1 and causing the test tube to burst and be damaged. At the same time, shaking can also be avoided during the lifting and lowering process of the placement plate 6. The setting of the sealing layer 3 and the thermal insulation layer 15 can keep the cold air inside the box 1 warm, reduce the loss of cold air, and prevent outside air and dust from entering the box 1.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
