DETAILED DESCRIPTION

[0019] like Figure 1-Figure 10 As shown, a cell freezing box storage tank with a rapid arrangement function includes a tank body 1, the top of the tank body 1 is sealed by an end cover 101, a rotating drum 11 is arranged inside the tank body 1, and the rotating drum 11 is coaxially arranged with the tank body 1, and a base 14 is fixedly arranged at the bottom end of the tank body 1, the top of the rotating drum 11 passes through the end cover 101 and rotates with it, and the bottom end of the rotating drum 11 is located in the base 14 and rotates with the base 14. Through this structure, the rotating drum 11 can be installed, and a supporting assembly for supporting a box body 12 for storing cells is arranged on the outside of the rotating drum 11. The supporting assembly includes an insert plate 10, which can be plugged into the outside of the rotating drum 11, and an opening 1001 is arranged on the insert plate 10 at the midline position, referring to Figure 3 As shown, the top of the opening 1001 is a closed structure, while the bottom of the opening 1001 is in an open state. A plurality of support plates 8 are fixedly installed on the outer side of the plug board 10, and the plurality of support plates 8 are evenly distributed in a linear array. Figure 3As shown, an L-shaped stopper 1301 is fixedly provided on the top of the support plate 8, and a slide plate 13 for supporting the box body 12 is slidably installed on the top of the support plate 8, and a driving assembly matched with the slide plate 13 is provided on the support plate 8, and a plurality of core barrels 3 are evenly arranged in the rotating drum 11, and the plurality of core barrels 3 are distributed in a ring array, and a core shaft 4 is coaxially arranged inside the core barrel 3, and a transmission unit matched with the driving assembly is arranged at the core barrel 3, and a pressure ring 401 is provided on the core shaft 4 below the transmission unit. In actual use, when the pressure ring 401 moves to the transmission unit, the transmission unit can cooperate with the drive assembly during the rotation of the rotating drum 11, thereby driving the slide plate 13 to move outward along the support plate 8, and in this process, the box body 12 can move in the direction away from the plug plate 10, thereby facilitating the corresponding box body 12 to be moved out of the tank body 1.

[0020] The driving assembly includes a spur gear 21 arranged at the support plate 8, and a rack 23 meshing with the spur gear 21 is fixedly embedded on the bottom surface of the skateboard 13, a rotating shaft 19 is arranged at the plug plate 10, and the rotating shaft 19 is rotatably connected to the plug plate 10, and a connecting shaft 22 is arranged at the support plate 8, and the connecting shaft 22 is rotatably matched with the support plate 8, and the above-mentioned spur gear 21 is sleeved on the outside of the connecting shaft 22, and the connecting shaft 22 and the rotating shaft 19 are matched through a belt 20, and a first bevel gear is sleeved on the outside of the rotating shaft 19.

[0021] The transmission unit comprises a transverse shaft 16, which passes through the wall of the drum 11 and rotates with the drum 11. The end of the transverse shaft 16 passing through the drum 11 is fixedly provided with a second bevel gear meshing with the first bevel gear, and the end of the transverse shaft 16 close to the core barrel 3 is connected with a driven bevel gear 15. The outer side of the core barrel 3 is rotatably sleeved with a driving bevel gear 17 meshing with the driven bevel gear 15. Furthermore, a block 18 is elastically mounted on the wall of the core barrel 3, and a plurality of slots matching the block 18 are evenly arranged on the inner wall of the active bevel gear 17. When one end of the block 18 is inserted into the slot, the core barrel 3 can drive the active bevel gear 17 to rotate during its self-rotation. Figure 7 As shown, the outer circumferential surface of the pressure ring 401 is provided with inclined conical surfaces 4011 at the top and bottom ends. When the core shaft 4 drives the pressure ring 401 to move to the block 18, the block 18 can be squeezed by the inclined conical surface 4011, so that one end of the block 18 is inserted into the groove. The pressure ring 401 can be rotatably installed on the outside of the core shaft 4 through the bearing. Of course, the pressure ring 401 can also be fixed on the outside of the core shaft 4.

[0022] Reference Figure 1-Figure 4As shown, a slide bar 9 is embedded in the inner wall of the tank body 1, and the slide bar 9 can move in the vertical direction 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. Figure 4 As shown, the support block 901 is a U-shaped structure as a whole, and a slot 9012 is formed on the support block 901. The outer side surface of the box body 12 is provided with an insert block 1201 that matches the support block 901 (the insert block 1201 and the box body 12 can be fixedly connected or elastically matched). When the slide plate 13 drives the box body 12 to move in a direction away from the core barrel 3, the insert block 1201 follows the box body 12 to rotate. The insert block 1201 can overlap with the support block 901, so that the insert block 1201 is plugged into the support block 901, and the box body 12 is retained at the support block 901. Figure 3 As shown, the plug block 1201 is set to a "┝" type, combined with Figure 4 , Fig.15 As shown, the top wall and the bottom wall of the slot 9012 are integrally formed with a retaining bar 9013 , and the retaining bar 9013 can prevent the insert block 1201 from moving in a direction away from the tank body 1 relative to the slot 9012 .

[0023] Reference Figure 6 As shown, a screw sleeve 5 is fixedly provided at a position near the top of the core barrel 3, and the part of the core shaft 4 near the top is threadedly matched with the screw sleeve 5. Through this structure, the core shaft 4 can move upward relative to the core barrel 3, so that the position of the pressure ring 401 relative to the block 18 can be adjusted.

[0024] Reference Figure 5 As shown, a driven gear is fixedly sleeved on the bottom end of the core barrel 3, and a gear ring 7 meshing with the driven gear is fixedly provided on the inner wall of the base 14. When the rotating drum 11 drives the core barrel 3 to rotate, the engagement of the driven gear and the gear ring 7 can drive the core barrel 3 to rotate.

[0025] Reference Figure 2-Figure 3 As shown, since the support plates 8 are provided with multiple groups, the transmission units and the pressure ring 401 matched therewith also need to be provided with multiple groups. In order to cryopreserve a variety of cells, the number of the plug plates 10 is also provided with multiple groups and distributed in a circular array on the outside of the rotating drum 11. The above-mentioned mandrels 4 correspond to the plug plates 10 one by one. In order to facilitate the retrieval of the frozen cells, the present scheme marks the multiple mandrels 4 (color marking or digital marking, etc.) so that each mandrel 4 can correspond to a different type of frozen cells. Of course, the present scheme also provides scale lines on the outer side surface of the mandrel 4. When the mandrel 4 is rotated to move upward relative to the core barrel 3, the scale lines on the mandrel 4 can correspond to the end surface of the screw sleeve 5, so that the upward movement distance of the pressure ring 401 can be controlled. Figure 6-Figure 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. 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 401 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 drum 11. 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 drum wall of the drum 11. 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 drum wall of the drum 11. 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. When the pressure ring 401 moves upward to align with the block 18, the inclined conical surface 4011 on the pressure ring 401 will squeeze the block 18, so that one end of the block 18 is inserted into the groove on the inner wall of the active bevel gear 17, so that the core barrel 3 can drive the active bevel gear 17 to rotate synchronously. When the rotating drum 11 is driven to rotate, the engagement of the driven gear and the ring gear 7 can drive the core barrel 3 to rotate, so that the engagement of the active bevel gear 17 and the driven bevel gear 15 can drive the horizontal shaft 16 to rotate, and the engagement of the first bevel gear and the second bevel gear can drive the rotating shaft 19 to rotate, and then the belt 20 drives the connecting shaft 22 to rotate, and the engagement of the spur gear 21 and the rack 23 can cause the slide plate 13 to move in the direction away from the rotating drum 11, thereby moving the test piece loaded on the slide plate 13 When the box body 12 of the tube is moved out, when the slide plate 13 and the box body 12 above the slide plate 13 move outward to the extreme position, the plug block 1201 on the box body 12 can overlap with the support block 901, so that as the box body 12 rotates with the drum 11, the plug block 1201 on the box body 12 can be inserted into the slot 9012 on the support block 901. At this time, the box body 12 can be supported by the support block 901, and as the drum 11 continues to rotate, the box body 12 plugged into the support block 901 will be separated from the slide plate 13. In this way, during the rotation of the drum 11, the multiple box bodies 12 moved outward can be plugged into the multiple support blocks 901 on one side of the slide bar 9 in turn. After that, the staff can lift the slide bar 9 upward to take out the multiple box bodies 12.

[0026] In summary, this device arranges multiple pressure rings 401 on the core shaft 4 and utilizes the different moving distances of the core shaft 4 relative to the core cylinder 3 to enable the pressure ring 401 on the core shaft 4 to cooperate with the card blocks 18 of different heights, so that the box bodies 12 on each plug plate 10 can be extracted at different heights, so that each box body 12 carrying different cells can be plugged into the support block 901, which is convenient for the staff to take it, and the overall operation is relatively convenient. Moreover, through the plug-in connection between the plug plate 10 and the rotating cylinder 11, the box bodies 12 storing cells can be quickly arranged in the tank body 1.

[0027] Combination Figure 10-11As shown, an insertion strip 1302 is fixedly provided on the bottom surface of the slide plate 13, and a mounting groove slidably matched with the insertion strip 1302 is provided on the top surface of the support plate 8. The cross-sections of the mounting groove and the insertion strip 1302 are both set to be T-shaped, and the end of the mounting groove away from the core barrel 3 is in an open state. An elastic rope 801 is fixedly provided between the end surface of the mounting groove close to the core barrel 3 and the insertion strip 1302. Through this structure, when the slide plate 13 moves outward to the extreme position, the spur gear 21 and the rack 23 are staggered, and the elastic rope 801 is in a tightened state. When the subsequent rotating drum 11 rotates in the opposite direction, the tension of the elastic rope 801 on the insertion strip 1302 enables the rack 23 to re-engage with the spur gear 21, which is beneficial to the resetting of the slide plate 13.

[0028] Combination Figure 12-13 As shown, a pressure rod 25 is slidably provided on the top surface of the slide plate 13, and the top end of the pressure rod 25 is a curved surface structure. A limit block 2202 is elastically installed on the outer peripheral surface of the connecting shaft 22, and a plurality of limit grooves cooperating with the limit block 2202 are provided on the inner wall of the spur gear 21. Further, a magnetic block 2201 is slidably mounted on the outer peripheral surface of the connecting shaft 22, and a pull rope 27 is fixedly provided between the magnetic block 2201 and the limit block 2202. The pull rope 27 passes through the connecting shaft 22 and slidably cooperates with it. The outer sliding sleeve of the connecting shaft 22 is provided with a collar 26, and a magnet 2601 matching with the magnetic block 2201 is fixedly embedded on the inner wall of the collar 26. The magnet 2601 can be arc-shaped, and the side of the magnet 2601 opposite to the magnetic block 2201 has different magnetic poles. The side of the pressure rod 25 close to the collar 26 is provided with an inclined extrusion portion 2501. When the pressure rod 25 moves downward, the collar 26 can be driven to move through the extrusion portion 2501, so that the magnet 2601 and the magnetic block 2201 are staggered. Fig.10 As shown, the support plate 8 is provided with a through groove for accommodating structures such as the belt 20 and the connecting shaft 22, and a limit spring is fixedly arranged between the collar 26 and the inner wall of the through groove. The limit spring is located on the side of the collar 26 away from the spur gear 21 and is sleeved on the outer side of the connecting shaft 22; 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, and then drive 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.

[0029] 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.

[0030] Combination Figure 1-Figure 2As shown, the end cover 101 is provided with a through slot 1011, and a sealing plate 2 for sealing the slot 1011 is installed on the end cover 101. When the box body 12 is engaged with the support block 901, the slide bar 9, the support block 901 and the box body 12 can pass through the slot 1011 during the upward movement of the slide bar 9, and the slide bar 9, the support block 901 and the box body 12 are in contact with the inner wall of the slot 1011. Through this structure, leakage of liquid nitrogen in the tank body 1 can be avoided 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-section of the receiving groove and the slide bar 9 can be T-shaped, so as 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 slot 1011.

[0031] A circular hole is provided on the outer side of the slide bar 9 near the bottom, and a latch 28 is slidably provided on the tank body 1. When the staff pulls the slide bar 9 upward, the slide bar 9 can be locked by the cooperation of the latch 28 and the circular hole.

[0032] Combination Figure 1-Figure 3 As shown, a positioning strip is fixedly arranged on the inner wall of the plug board 10, and a positioning groove 1101 is provided on the outer wall of the drum 11 to slide with the positioning strip. The cross sections of the positioning strip and the positioning groove 1101 are both set to be T-shaped. Figure 1 As shown, a sealing ring 6 can be sleeved on the top of the rotating drum 11, and a convex strip matching the positioning groove 1101 is fixedly provided on the inner wall of the sealing ring 6. Through this structure, on the one hand, the positioning groove 1101 can be sealed, and on the other hand, a handle can be fixedly installed on the outside of the sealing ring 6 to drive the rotating drum 11 to rotate. Of course, the rotating drum 11 can also be driven to rotate by external power.

[0033] The top end of the rotating drum 11 is a closed structure, while the bottom end of the rotating drum 11 is an open structure. The top end of the core tube 3 passes through the rotating drum 11 and rotates in cooperation therewith.

[0034] Combination Figure 4 As shown, a stop block 9011 can be elastically installed on the inner bottom surface of the support block 901, and the top of the stop block 9011 is an arc surface.
