DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the purpose, technical solution and advantages of the technical solution clearer and more understandable, the following further details the technical solution in combination with specific embodiments. It should be understood that these descriptions are exemplary and not intended to limit the scope of the technical solution.

[0024] Please refer to Figures 1-6, the present utility model provides a technical solution: an immune cell storage device, comprising a storage tank 1, a plurality of limiting rings 2 and a selection component 4. The storage tank 1 includes a tank body 11 and a tank cover 12. A plurality of limiting rings 2 are fixedly arranged on the inner side wall of the tank body 11. One of the limiting rings 2 is missing and a vacancy 3 is formed at the corresponding position. The selection component 4 is arranged on the bottom surface of the tank cover 12. The selection component 4 includes a motor 41, a driving rod 42 and a force application plate 43. The motor 41 is fixedly connected to the tank cover 12. Two ends of the driving rod 42 are respectively connected to the output end of the motor 41 and the force application plate 43.

[0025] Please refer to Figures 1-3 and Figure 6 , when the present utility model is in use, the tank cover 12 can move upward to be separated from the tank body 11. Then, test tubes 10 containing immune cells can be placed into the plurality of limiting rings 2. Finally, the tank cover 12 and the tank body 11 are tightened. In the present utility model, there is a good seal between the tank body 11 and the tank cover 12. An opening is provided on the tank cover 12, and liquid nitrogen can be injected into the tank body 11 through the opening.

[0026] Please refer to Figures 2-3 , when it is necessary to continue to place test tubes 10 into the tank body 11, the motor 41 operates to drive the driving rod 42 to rotate. The driving rod 42 drives the force application plate 43 to move to the vacancy 3. At this time, the tank cover 12 moves upward, and the force application plate 43 does not contact any test tube 10. After the tank cover 12 is separated from the tank body 11, test tubes 10 containing immune cells can be placed into the remaining empty limiting rings 2.

[0027] Please refer to Figures 2-3 , when it is necessary to take out a test tube 10, the motor 41 operates, and drives the force application plate 43 to move below a specific test tube 10 through the driving rod 42. Next, the tank cover 12 moves upward. After the force application plate 43 contacts the bottom of the test tube 10, the test tube 10 is driven to move upward. During this process, the test tube 10 can slide along the inner side wall of the limiting ring 2, so it can move smoothly. After the tank cover 12 is separated from the tank body 11, the lifted test tube 10 can be taken away.

[0028] The present utility model can lift the test tubes 10 containing immune cells through the selection component 4. In addition, due to the existence of the vacancy 3 between the plurality of limiting rings 2, the driving rod 42 can drive the force application plate 43 to move to the vacancy 3 after rotation, so that the test tubes 10 inside the storage tank 1 will not be taken out when the tank cover 12 moves upward.

[0029] Please refer to Figures 2-3 and Figure 5, the utility model further includes a supporting component 5. The supporting component 5 includes a plurality of supporting plates 51, and the plurality of supporting plates 51 are all fixedly arranged on the inner side wall of the tank body 11. A positioning cavity 6 is formed jointly between the plurality of supporting plates 51 and the inner bottom surface of the tank body 11. The force-applying plate 43 is arranged in the positioning cavity 6, and a lifting channel 7 is arranged between two adjacent supporting plates 51. There are two symmetrically mirror-structured supporting seats 52 directly below each limiting ring 2. A first arc-shaped groove 521 is arranged at the top of the supporting seat 52.

[0030] Please refer to Figures 2-3 and Figure 6 , when the test tube 10 is placed inside the tank body 11, the bottom of the test tube 10 will enter the first arc-shaped groove 521, and the supporting seat 52 provides a supporting force to the test tube 10. When it is necessary to remove the test tube 10, the motor 41 works, drives the force-applying plate 43 to rotate in the positioning cavity 6 through the driving rod 42 until the force-applying plate 43 moves below one of the lifting channels 7. Next, the tank cover 12 moves upward. The force-applying plate 43 first passes through the lifting channel 7, then enters between two adjacent supporting seats 52, and finally contacts the bottom of the test tube 10 to drive the test tube 10 to move upward. After the test tube 10 is removed, the tank cover 12 moves downward, and the force-applying plate 43 returns to the positioning cavity 6.

[0031] Please refer to Figures 2-4 , the force-applying plate 43 includes a first connecting plate 431 and a second connecting plate 432. The cross-section of the first connecting plate 431 is circular. One end of the plurality of supporting plates 51 away from the inner side wall of the tank body 11 jointly encloses an avoidance position 8, and the avoidance position 8 corresponds to the position of the first connecting plate 431, and the shape of the avoidance position 8 matches the shape of the first connecting plate 431. When the driving rod 42 rotates, it will drive the first connecting plate 431 to rotate, and then drive the second connecting plate 432 to rotate. When the tank cover 12 moves upward or downward, the first connecting plate 431 will pass through the position of the avoidance position 8.

[0032] Please refer to Figure 4 , the width of the first end of the second connecting plate 432 is smaller than the width of the second end. A rubber pad 433 is arranged on the top surface of the second end of the second connecting plate 432 to ensure that there is a large enough contact area between the rubber pad 433 and the bottom of the test tube 10, reduce the impact on the test tube 10, and prevent the test tube 10 from being damaged when contacting the second connecting plate 432. The shape of the lifting channel 7 matches the shape of the second connecting plate 432. When the tank cover 12 moves upward or downward, the second connecting plate 432 will pass through the position of the lifting channel 7.

[0033] Please refer to Figure 4, the radius of the first connecting plate 431 is greater than one-third of the length of the second connecting plate 432. Therefore, the distance between two adjacent lifting channels 7 can be shortened, and further the distance between several limiting rings 2 can be shortened, so that more limiting rings 2 can be arranged on the inner wall of the can body 11.

[0034] Please refer to Figure 2 , the second end of the second connecting plate 432 abuts against the inner side wall of the can body 11. When the driving rod 42 drives the force-applying plate 43 to rotate, the force-applying plate 43 can slide along the inner side wall of the can body 11, ensuring the stability of the force-applying plate 43 during the movement.

[0035] Please refer to Figures 1-3 and Figure 6 , the present utility model further includes a control component 9. The control component 9 includes a controller 91 and an electric telescopic rod 92. The controller 91 is fixedly arranged on the outer side wall of the can body 11, and the position of the controller 91 corresponds to the position of the vacant position 3. The controller 91 can control the extension and shortening of the electric telescopic rod 92. When the electric telescopic rod 92 extends, it can drive the can lid 12 to move upward and separate from the can body 11. When the electric telescopic rod 92 shortens, it can drive the can lid 12 to move downward and tightly cover the can body 11. A touch display screen 911 is arranged on the controller 91. A weight sensor can be arranged on the supporting seat 52. When a test tube 10 is placed in the can body 11, the weight sensor transmits a signal to the controller 91, and the specific position of the test tube 10 can be displayed on the touch display screen 911.

[0036] Please refer to Figures 2-3 and Figure 6 , a plurality of second arc-shaped grooves 111 are arranged on the inner side wall of the can body 11, and the positions of the plurality of second arc-shaped grooves 111 respectively correspond to the positions of the plurality of limiting rings 2. The top of the second arc-shaped groove 111 is located above the limiting ring 2 and penetrates through the top surface of the can body 11, and the bottom of the second arc-shaped groove 111 is located inside the limiting ring 2.

[0037] When placing the test tube 10 into the can body 11, the test tube 10 can be slightly tilted first to make the bottom of the test tube 10 extend into the second arc-shaped groove 111, then the test tube 10 is inserted into the limiting ring 2, and finally the test tube 10 is pushed downward, and the test tube 10 can automatically return to the upright position. When the test tube 10 needs to be taken away, the electric telescopic rod 92 extends to drive the can lid 12 to move upward. The can lid 12 drives the force-applying plate 43 to move upward through the motor 41 and the driving rod 42. When the force-applying plate 43 contacts the bottom surface of the limiting ring 2, the electric telescopic rod 92 stops extending. At this time, the top of the lifted test tube 10 has moved above the can body 11. Next, the test tube 10 is slightly tilted to make the test tube 10 enter the second arc-shaped groove 111, and then the test tube 10 can be taken away.

[0038] When the utility model is in use, during the process of putting in or taking out the test tube 10, the test tube 10 can tilt into the second arc-shaped groove 111, so that the test tube 10 can be prevented from colliding with the can lid 12.

[0039] The above content is only the preferred embodiment of the utility model. For those of ordinary skill in the art, according to the idea of the technical content, many changes can be made in the specific implementation manner and application scope. As long as these changes do not deviate from the concept of the utility model, they all belong to the protection scope of this patent.
