Detailed implementation manner

[0035] As Figures 1 - 10 shown, a cell cryopreservation box storage tank with a fast arrangement function includes a tank body 1. The top of the tank body 1 is sealed by an end cover 101. A rotating cylinder 11 is arranged inside the tank body 1, and the rotating cylinder 11 is coaxially arranged with the tank body 1. A base 14 is fixedly arranged at the bottom end inside the tank body 1. The top end of the rotating cylinder 11 passes through the end cover 101 and is rotatably matched with it, while the bottom end of the rotating cylinder 11 is located inside the base 14 and is rotatably matched with the base 14. Through this structure, the rotating cylinder 11 can be installed. A support assembly for supporting the box body 12 for storing cells is arranged on the outer side of the rotating cylinder 11. The support assembly includes an insertion plate 10. The insertion plate 10 can be inserted on the outer side of the rotating cylinder 11. An opening 1001 is arranged at the middle line position on the insertion plate 10. Referring to Figure 3 shown, the top end of the opening 1001 is a closed structure, while the bottom end of the opening 1001 is in an open state. A plurality of support plates 8 are fixedly installed on the outer side surface of the insertion plate 10. The plurality of support plates 8 are evenly distributed in a linear array. Referring toFigure 3 As shown, a stop portion 1301 in the shape of an L is fixedly arranged on the top of the support plate 8. A slide plate 13 for supporting the box body 12 is slidably assembled on the top of the support plate 8. A driving assembly cooperating with the slide plate 13 is arranged on the support plate 8. A plurality of core cylinders 3 are uniformly arranged in the rotating cylinder 11. The plurality of core cylinders 3 are distributed in an annular array. A core shaft 4 is coaxially arranged inside the core cylinder 3. A transmission unit cooperating with the driving assembly is arranged at the core cylinder 3. A pressing ring 401 is arranged below the transmission unit on the core shaft 4. During actual use, when the pressing ring 401 moves to the position of the transmission unit, during the rotation of the rotating cylinder 11, the transmission unit can be in transmission cooperation with the driving assembly, thereby driving the slide plate 13 to move outwards along the support plate 8. During this process, the box body 12 can move away from the plug plate 10, which is beneficial to moving the corresponding box body 12 out of the tank body 1.

[0036] The driving assembly includes a spur gear 21 arranged at the support plate 8. A rack 23 meshing with the spur gear 21 is fixedly embedded in the bottom surface of the slide plate 13. A rotating shaft 19 is arranged at the plug plate 10. The rotating shaft 19 is rotatably connected with the plug plate 10. A connecting shaft 22 is arranged at the support plate 8. The connecting shaft 22 is rotatably matched with the support plate 8. The above-mentioned spur gear 21 is sleeved outside the connecting shaft 22. The connecting shaft 22 and the rotating shaft 19 are in transmission cooperation through a belt 20. A first bevel gear is sleeved outside the rotating shaft 19.

[0037] The above-mentioned transmission unit includes a cross shaft 16. The cross shaft 16 passes through the cylinder wall of the rotating cylinder 11 and is rotatably matched with the rotating cylinder 11. A second bevel gear meshing with the first bevel gear is fixedly arranged at one end of the cross shaft 16 passing out of the rotating cylinder 11. One end of the cross shaft 16 close to the core cylinder 3 is connected with a driven bevel gear 15. A driving bevel gear 17 meshing with the driven bevel gear 15 is rotatably sleeved outside the core cylinder 3;

[0038] Further, a clamping block 18 is elastically installed on the cylinder wall of the core cylinder 3. A plurality of card slots cooperating with the clamping block 18 are uniformly formed on the inner wall of the driving bevel gear 17. When one end of the clamping block 18 is inserted into the card slot, the core cylinder 3 can drive the driving bevel gear 17 to rotate during the rotation process, referring to Figure 7 As shown, inclined conical surfaces 4011 are arranged at both the top and bottom positions on the outer peripheral surface of the pressing ring 401. When the core shaft 4 drives the pressing ring 401 to move to the position of the clamping block 18, the inclined conical surfaces 4011 can squeeze the clamping block 18, so that one end of the clamping block 18 is inserted into the card slot. The pressing ring 401 can be rotatably installed outside the core shaft 4 through a bearing. Of course, the pressing ring 401 can also be fixed outside the core shaft 4.

[0039] Referring to Figures 1 - 4As shown, a slide bar 9 is embedded in the inner wall of the tank body 1. The slide bar 9 can move vertically relative to the tank body 1, and a plurality of support blocks 901 are fixedly arranged on the inner wall of the slide bar 9. Combining Figure 4 As shown, the support block 901 is of a U-shaped structure as a whole, and a slot 9012 is formed on the support block 901. An insertion block 1201 (the insertion block 1201 can be fixedly connected or elastically matched with the box body 12) that cooperates with the support block 901 is arranged on the outer side of the box body 12. When the slide plate 13 drives the box body 12 to move away from the core cylinder 3, during the rotation of the insertion block 1201 following the box body 12, the insertion block 1201 can coincide with the support block 901, so that the insertion block 1201 is inserted into the support block 901, and the box body 12 is retained at the support block 901. Referring to Figure 3 As shown, the insertion block 1201 is set in a "┝" shape. Combining Figure 4 、 Figure 15 As shown, stop bars 9013 are integrally formed on the top wall and the bottom wall inside the slot 9012. By arranging the stop bars 9013, the insertion block 1201 can be prevented from moving away from the tank body 1 relative to the slot 9012.

[0040] Referring to Figure 6 As shown, a screw sleeve 5 is fixedly arranged at a position near the top inside the core cylinder 3, and a part near the top of the core shaft 4 is in threaded cooperation with the screw sleeve 5. With this structure, the core shaft 4 can move upward relative to the core cylinder 3, so as to adjust the position of the pressure ring 401 relative to the clamping block 18.

[0041] Referring to Figure 5 As shown, a driven gear is fixedly sleeved at the bottom end of the core cylinder 3, and a toothed ring 7 that meshes with the driven gear is fixedly arranged on the inner wall of the base 14. When the rotating cylinder 11 drives the core cylinder 3 to rotate, the core cylinder 3 can be driven to rotate self by the meshing of the driven gear and the toothed ring 7.

[0042] Referring to Figures 2 - 3 As shown, since there are multiple groups of support plates 8, accordingly, multiple groups of the matching transmission units and pressure rings 401 also need to be arranged. In order to freeze multiple types of cells, the number of the insertion plates 10 is also set to be multiple groups and is distributed in an annular array outside the rotating cylinder 11. The above-mentioned core shafts 4 correspond to the insertion plates 10 one by one. In order to facilitate the taking of the frozen cells, the multiple core shafts 4 in this solution are marked (color marking or digital marking etc. can be adopted), so that each core shaft 4 can correspond to different types of frozen cells. Of course, scale lines are also arranged on the outer side of the core shaft 4 in this solution. When the core shaft 4 is rotated to move upward relative to the core cylinder 3, the scale lines on the core shaft 4 can correspond to the end face of the screw sleeve 5, so as to control the moving distance of the pressure ring 401 upward. Referring to Figures 6 - 7As shown, the distances between the multiple pressing rings 401 and the corresponding blocks 18 gradually increase from bottom to top. Through this structure, when the rotating mandrel 4 drives the pressing ring 401 to move upward by different distances, the multiple pressing rings 401 will cooperate with each block 18 in sequence from bottom to top. Specifically, when the mandrel 4 moves upward by a certain distance so that the pressing ring 401 at the bottom cooperates with the block 18 near it, the remaining pressing rings 401 are all below the block 18. When the penultimate pressing ring 401 cooperates with the block 18 near it, the pressing ring 401 at the bottom is staggered with the block 18 near it, and the remaining pressing rings are still below the block 18, and so on.

[0043] When it is necessary to take out the corresponding frozen cells, the core shaft 4 can be rotated to make the core shaft 4 move upward relative to the core barrel 3, so that the pressure ring 401 on the core shaft 4 is aligned with the corresponding block 18. Specifically, when it is necessary to take out multiple cells, multiple core shafts 4 can be rotated, and during the rotation process, the rotation height of each core shaft 4 increases in sequence. As the distance the core shaft 4 moves upward increases, the distance the pressure ring 401 on the core shaft 4 moves upward increases. According to the above description, the pressure ring 401 on each core shaft 4 can cooperate with different blocks 18, so that the distance that each core shaft 4 drives the pressure ring 401 to move upward increases in sequence. For example, the first core shaft 4 rotates During the process, the rotation can be stopped after the bottom pressure ring 401 on the mandrel 4 is aligned with the bottom block 18 on the core barrel 3. During the rotation of the second mandrel 4, the rotation of the mandrel 4 can be stopped by aligning the second-to-last pressure ring 401 on the mandrel 4 with the second-to-last block 18 on the wall of the core barrel 3. Specifically, when the second-to-last pressure ring 401 on the mandrel 4 is aligned with the block 18, the bottom pressure ring 401 on the mandrel 4 will move upward and stagger with the bottom block 18 on the wall of the core barrel 3. In this way, the pressure rings 401 on multiple mandrels 4 can be matched with the blocks 18 at different heights in sequence from bottom to top.

[0044] During the upward movement of the pressing ring 401 to align with the clamping block 18, the inclined conical surface 4011 on the pressing ring 401 will squeeze the clamping block 18, causing one end of the clamping block 18 to insert into the clamping groove on the inner wall of the driving bevel gear 17, enabling the core barrel 3 to drive the driving bevel gear 17 to rotate synchronously. When driving the rotating cylinder 11 to rotate, the core barrel 3 can be driven to rotate self - by the meshing of the driven gear and the toothed ring 7. Thus, the transverse shaft 16 can be driven to rotate through the meshing of the driving bevel gear 17 and the driven bevel gear 15, and the rotating shaft 19 can be driven to rotate through the meshing of the first bevel gear and the second bevel gear. Furthermore, the connecting shaft 22 can be driven to rotate through the belt 20. The sliding plate 13 can be prompted to move away from the rotating cylinder 11 through the meshing of the spur gear 21 and the rack 23, thereby moving out the box body 12 carrying the test tube above the sliding plate 13. When the sliding plate 13 and the box body 12 above the sliding plate 13 move outwards to the limit position, the insertion block 1201 on the box body 12 can coincide with the support block 901. When the box body 12 rotates with the rotating cylinder 11, the insertion block 1201 on the box body 12 can insert into the slot 9012 on the support block 901. At this time, the support block 901 can support the box body 12. As the rotating cylinder 11 continues to rotate, the box body 12 inserted into the support block 901 will separate from the sliding plate 13. In this way, during the rotation of the rotating cylinder 11, the multiple box bodies 12 moved outwards can be sequentially inserted into the multiple support blocks 901 on one side of the sliding bar 9. After that, the staff can lift the sliding bar 9 upwards to take out the multiple box bodies 12.

[0045] In summary, this device arranges multiple pressing rings 401 on the core shaft 4. By utilizing the different distances of the relative movement between the core shaft 4 and the core barrel 3, it can prompt the pressing rings 401 on the core shaft 4 to cooperate with the clamping blocks 18 at different heights, thereby enabling the extraction of the box bodies 12 on each inserting plate 10 at different heights, allowing the box bodies 12 carrying different cells to be inserted into the support blocks 901, which is beneficial for the staff to take. The overall operation is relatively convenient. Moreover, through the insertion connection between the inserting plate 10 and the rotating cylinder 11, the box bodies 12 storing cells can be quickly arranged in the tank body 1.

[0046] Combined with Figures 10 - 11As shown, an insertion bar 1302 is fixedly provided on the bottom surface of the skateboard 13, and an installation groove that slidably mates with the insertion bar 1302 is formed on the top surface of the support plate 8. The cross-sections of both the installation groove and the insertion bar 1302 are T-shaped. One end of the installation groove far from the core cylinder 3 is in an open state. An elastic cord 801 is fixedly provided between the end face of the installation groove close to the core cylinder 3 and the insertion bar 1302. With this structure, when the skateboard 13 moves outward to the extreme position, the spur gear 21 and the rack 23 are staggered, and the elastic cord 801 is in a tensioned state. When the drum 11 rotates in the reverse direction subsequently, the tension of the elastic cord 801 on the insertion bar 1302 enables the rack 23 to mesh with the spur gear 21 again, which is beneficial for the reset of the skateboard 13.

[0047] Combined with Figures 12 - 13 As shown, a pressure rod 25 is slidably provided on the top surface of the skateboard 13. The top end of the pressure rod 25 has an arc-shaped structure. A limiting block 2202 is elastically installed on the outer peripheral surface of the connecting shaft 22. A plurality of limiting grooves that cooperate with the limiting block 2202 are formed on the inner wall of the spur gear 21. Further, a magnetic block 2201 is slidably assembled on the outer peripheral surface of the connecting shaft 22. A pulling cord 27 is fixedly provided between the magnetic block 2201 and the limiting block 2202. The pulling cord 27 passes through the connecting shaft 22 and slidably mates with it. A collar 26 is slidably sleeved on the outer side of the connecting shaft 22. A magnet 2601 that cooperates with the magnetic block 2201 is fixedly embedded on the inner wall of the collar 26. The magnet 2601 can be arc-shaped. The surfaces of the magnet 2601 and the magnetic block 2201 facing each other have different magnetic poles. An inclined pressing portion 2501 is provided on one side of the pressure rod 25 close to the collar 26. When the pressure rod 25 moves downward, the collar 26 can be driven to move through the pressing portion 2501, so that the magnet 2601 and the magnetic block 2201 are staggered. Refer to Figure 10 As shown, a through groove for accommodating structures such as the belt 20 and the connecting shaft 22 is formed on the support plate 8. A limiting spring is fixedly provided between the collar 26 and the inner wall of the through groove. The limiting spring is located on the side of the collar 26 far from the spur gear 21 and is sleeved on the outer side of the connecting shaft 22;

[0048] In actual use, after the box body 12 is engaged with the support block 901 and separated from the slide plate 13, the force of the limit spring on the collar 26 can cause the collar 26 to move away from the spur gear 21, thereby pushing the pressure rod 25 upward, and the magnet 2601 on the collar 26 is aligned with the magnetic block 2201 on the connecting shaft 22, and the suction force between the two can pull the pull rope 27, so that one end of the limit block 2202 moves out of the limit groove, so that the connection shaft 22 and the spur gear 21 are connected. Disengagement, the purpose of such design is: when the researchers need to store the box body 12 back inside the tank body 1, they can press the slide bar 9 to drive the support block 901 and the corresponding box body 12 to move downward, so that the box bodies 12 of different heights can correspond to the slide plates 13 extending from each plug plate 10, and when the drum 11 is rotated in the opposite direction, the engagement of the driven gear and the ring gear 7 can drive the drum 11 to rotate in the opposite direction, thereby driving the connecting shaft 22 to rotate in the opposite direction, but because the connecting shaft 22 is disengaged from the spur gear 21, the slide plate 13 will not be retracted, and when the corresponding slide plate 13 moves to the bottom of the box body 12, the stopper 1301 on the top of the support plate 8 can push the box body 12, so that the box body 12 moves out of the support block 901 and falls onto the slide plate 13, at this time, the pressure of the box body 12 on the pressure rod 25 can drive the pressure rod 25 to move downward, and the pressure of the extrusion part 2501 on the ring 26 allows the ring 26 to gradually approach the spur gear 21, so that the magnet 26 01 is offset from the magnetic block 2201, so that the limit block 2202 can pop out again and cooperate with the limit groove. At this point, the connecting shaft 22 and the spur gear 21 are re-matched, so that the connecting shaft 22 can drive the spur gear 21 to rotate again, thereby retracting the slide plate 13 and the box body 12 above the slide plate 13 for the next use. In summary, through this structure, the slide plate 13 can only be retracted when the box body 12 falls onto the slide plate 13, so that the box body 12 can be completely placed on the slide plate 13.

[0049] In actual use, a compression spring can be installed on the end face of the core tube 3 in the installation groove. When the slide plate 13 is retracted onto the support plate 8, the spur gear 21 and the rack 23 are staggered, and the insertion strip 1302 can press the compression spring, which is conducive to the next meshing of the rack 23 and the spur gear 21.

[0050] Combination Figures 1 - 2As shown, a through notch 1011 is provided on the end cap 101, and a sealing plate 2 for sealing the notch 1011 is installed on the end cap 101. When the box body 12 is clamped with the support block 901, during the upward movement of the slide bar 9, the slide bar 9, the support block 901, and the box body 12 can pass through the notch 1011, and the slide bar 9, the support block 901, and the box body 12 are in contact with the inner wall of the notch 1011. With this structure, it is possible to prevent the liquid nitrogen in the tank body 1 from leaking during the process of taking cells. A receiving groove that slidably cooperates with the slide bar 9 is provided on the inner wall of the tank body 1. Of course, the cross-sections of the receiving groove and the slide bar 9 can be T-shaped to improve the stability of the cooperation between the slide bar 9 and the tank body 1. When the sealing plate 2 is opened, the slide bar 9 can be pulled out through the notch 1011.

[0051] A round hole is provided at a position near the bottom end on the outer side of the slide bar 9, and a plug pin 28 is slidably arranged on the tank body 1. After the staff member pulls the slide bar 9 upward, the slide bar 9 can be locked through the cooperation of the plug pin 28 and the round hole.

[0052] Combined with Figures 1 - 3 As shown, positioning strips are fixedly arranged on the inner wall of the insertion plate 10, and positioning grooves 1101 that slidably cooperate with the positioning strips are provided on the outer wall of the rotating cylinder 11. The cross-sections of the positioning strips and the positioning grooves 1101 are both set to be T-shaped.
