DETAILED DESCRIPTION

[0020] like Figure 1-Figure 10 As shown, a cell storage device and storage method with protective function comprises a box body 1 and a cover plate 101 hinged to the top of the box body 1. A partition plate 2 is fixedly installed in the box body 1. In order to store the test tubes containing cells, a plurality of stepped holes 202 are evenly opened on the partition plate 2. Figure 2 As shown, a plurality of support plates 3 for supporting the test tubes are arranged below the partition plate 2 , and the support plates 3 are vertically aligned with the stepped holes 202 , so that the test tubes can fall onto the support plates 3 after passing through the stepped holes 202 .

[0021] In order to install the support plate 3, in this solution, a vertical rod 6 is fixedly arranged between the partition plate 2 and the inner bottom surface of the box body 1, and the vertical rod 6 passes through the support plate 3 and slides with it; Reference Figure 3-Figure 5 As shown, a first pressing block 7 and a second pressing block 8 are respectively arranged on both sides of the top of the support plate 3, and the first pressing block 7 and the second pressing block 8 are elastically matched with the support plate 3, as shown in FIG. Figure 3 As shown, an inclined guide surface 701 is provided on one side opposite to the first pressing block 7 and the second pressing block 8. When the test tube passes through the stepped hole 202 and is inserted between the first pressing block 7 and the second pressing block 8, the test tube can drive the first pressing block 7 and the second pressing block 8 to move away from each other.

[0022] A rotating shaft 5 is arranged on one side of the support plate 3, and the rotating shaft 5 is rotatably installed between the partition plate 2 and the bottom surface of the box body 1. The support plate 3 can move in the vertical direction relative to the rotating shaft 5, and the support plate 3 cooperates with the rotating shaft 5 through a limiting component. In actual use, after the test tube is inserted between the first pressing block 7 and the second pressing block 8 and drives the first pressing block 7 to move outward a certain distance relative to the support plate 3, the support plate 3 cooperates with the rotating shaft 5 through the limiting component, so that the support plate 3 can drive the rotating shaft 5 to rotate during the movement of the supporting plate 3 relative to the rotating shaft 5, and the upper position of the partition plate 2 A sealing plate 201 is hinged at the position of the stepped hole 202. When the sealing plate 201 is deflected to a horizontal state, it can cover the top of the stepped hole 202, thereby facilitating sealing the top end of the test tube. The sealing plate 201 and the rotating shaft 5 are matched through a snap-fit ​​assembly. When the sealing plate 201 covers the top of the stepped hole 202, the rotating shaft 5 can be limited by the snap-fit ​​assembly to prevent the rotating shaft 5 from continuing to rotate. During this process, the support plate 3 will also remain stable. At this point, the test tube is stably placed between the sealing plate 201 and the support plate 3.

[0023] The above-mentioned limiting assembly includes a connecting rod 11 arranged below the first pressing block 7, the connecting rod 11 and the support plate 3 are rotatably matched through a bearing, a base 12 is sleeved on the outer side of the connecting rod 11, and the base 12 is fixedly arranged at the bottom end surface of the first pressing block 7. Specifically, a through hole matching the connecting rod 11 is opened on the base 12, so that the connecting rod 11 can pass through the through hole and the base 12 can move relative to the connecting rod 11. Figure 4 As shown, an inclined inclined groove 1101 and a horizontal straight groove 1102 are provided on the outer peripheral wall of the connecting rod 11, and the straight groove 1102 is connected with the inclined groove 1101. A protrusion 1201 is fixedly provided on the inner wall of the through hole, and the protrusion 1201 can slide along the inclined groove 1101 and the straight groove 1102. In the initial state, the base 12 is located at the inclined groove 1101 and the protrusion 1201 is inserted into the inclined groove 1101. When the first pressing block 7 moves outward relative to the support plate 3, the protrusion 1201 can slide along the inclined groove 1101, thereby driving the connecting rod 11 to rotate; The end of the connecting rod 11 close to the rotating shaft 5 passes through the supporting plate 3 and is fixedly provided with a rotating disk 10. Figure 3 , Figure 5-Figure 7 As shown, a columnar slider 4 is provided at one end of the turntable 10 away from the support plate 3, and the slider 4 is fixedly connected to the support plate 3, and the rotating shaft 5 passes through the slider 4 and slides with it. Figure 3As shown, a spiral limiting groove 501 is provided on the outer peripheral wall of the rotating shaft 5, and a limiting rod 16 matching the limiting groove 501 is elastically mounted on the slider 4. When one end of the limiting rod 16 is inserted into the limiting groove 501, the rotating shaft 5 can be driven to rotate as the support plate 3 and the slider 4 move in the vertical direction. Combination Figure 7 As shown, a magnetic plate 1001 is fixedly embedded on one end surface of the turntable 10 close to the slider 4, and a magnetic sheet can be fixedly embedded on one end surface of the slider 4 close to the turntable 10, and the magnetic plate 1001 has different magnetic poles on the side opposite to the magnetic sheet. In the initial state, the magnetic plate 1001 and the limit rod 16 are staggered in the horizontal direction. When the protrusion 1201 on the base 12 slides from the inclined groove 1101 to the inside of the straight groove 1102 and drives the connecting rod 11 to rotate a certain angle, the magnetic plate 1001 and the limit rod 16 can be in a colinear state; Furthermore, a positioning hole 503 is provided in the limiting groove 501 at a side opposite to the limiting rod 16 and near the top. In the initial state, the slider 4 is located at the positioning hole 503, and one end of the limiting rod 16 is inserted into the positioning hole 503. Through this structure, the support plate 3 can be kept stable, thereby preventing the support plate 3 from moving downward.

[0024] The above-mentioned clamping assembly includes an insertion rod 15 arranged on the side of the sealing plate 201 away from the stepped hole 202, and a socket 502 matching with the insertion rod 15 is opened on the outer peripheral wall of the rotating shaft 5 and near the top, and the number of the sockets 502 is set to be multiple and distributed in a circular array, and a pressure plate 14 is fixedly arranged at the end of the insertion rod 15 away from the rotating shaft 5, and the pressure plate 14 is elastically matched with the partition 2, and a magnetic block 13 is arranged at a position of the sealing plate 201 close to the pressure plate 14, and a magnet is fixedly embedded on the side of the pressure plate 14 away from the insertion rod 15. When the cover plate 101 is in a horizontal state, the magnetic block 13 is aligned with the magnet, and the side of the magnetic block 13 opposite to the magnet has the same magnetic pole.

[0025] In actual use, the test tube containing cells is passed downward through the stepped hole 202 and inserted between the first pressing block 7 and the second pressing block 8. During this process, the first pressing block 7 and the second pressing block 8 can be driven to move outward relative to the support plate 3. As the first pressing block 7 and the base 12 at the bottom thereof move outward relative to the support plate 3, the protrusion 1201 and the inclined groove 1101 cooperate to drive the connecting rod 11 to rotate. When the protrusion 1201 slides from the inclined groove 1101 to the inside of the straight groove 1102, the connecting rod 11 can It can be known from the above description that when the connecting rod 11 rotates so that the magnetic plate 1001 on the turntable 10 is aligned with the limiting rod 16 on the slider 4, the limiting rod 16 can be driven to move away from the rotating shaft 5 through the attraction between the magnetic plate 1001 and the magnetic sheet, so that one end of the limiting rod 16 is separated from the positioning hole 503. At this time, the support plate 3 will drive the turntable 10 and the slider 4 to move downward synchronously, and the rotating shaft 5 can be driven to rotate through the cooperation of the limiting rod 16 and the spiral limiting groove 501; When the test tube is inserted between the first pressing block 7 and the second pressing block 8, the staff can flip the sealing plate 201 so that the sealing plate 201 fits the outside of the test tube. During the specific installation, the hinged position of the sealing plate 201 and the partition 2 is outside the stepped hole 202. Therefore, when the sealing plate 201 fits on the test tube, the sealing plate 201 is in an inclined state as a whole. When the test tube gradually moves downward with the support plate 3, the sealing plate 201 can gradually deflect to the horizontal direction. Specifically, when the top end face of the test tube is flush with the top surface of the partition 2, the sealing plate 201 can deflect to a horizontal state and cover the top end of the test tube. When the sealing plate 201 is deflected to a horizontal state, the magnetic block 13 on the sealing plate 201 can be aligned with the magnet on the pressure plate 14. Through the repulsion between the magnetic block 13 and the magnet The force can drive the insertion rod 15 to move in the direction close to the rotating shaft 5. When one end of the insertion rod 15 is inserted into the inside of the socket 502, the rotating shaft 5 can stop rotating. At this time, the slider 4 can be limited by the cooperation of the limiting groove 501 and the limiting rod 16, thereby preventing the slider 4 and the support plate 3 from continuing to move downward. At this point, the test tube containing cells is placed between the sealing plate 201 and the support plate 3, which can improve the stability of the test tube during transportation. In addition, for test tubes of different sizes (different heights or different diameters), this device can keep the top end surface of the test tube roughly flush with the top surface of the partition 2. When the cover 101 is closed later, multiple test tubes can be fixed uniformly, thereby further improving the stability of the test tube placement.

[0026] To summarize, this device cooperates with the clamping assembly through the set limit assembly. When the test tube moves downward with the support plate 3 and the top end face of the test tube is flush with the top surface of the partition 2, the sealing plate 201 can be deflected to a horizontal state. During this process, the rotating shaft 5 can be locked by the insertion rod 15 to prevent the rotating shaft 5 from continuing to rotate, and then the position of the support plate 3 can be locked, so that the test tube is placed between the support plate 3 and the sealing plate 201, which is beneficial to improve the stability of the test tube during transportation. In addition, for test tubes of different sizes, this solution can further fix the test tube through the cover plate 101 after closing the cover plate 101.

In actual use, when the test tube is placed between the support plate 3 and the sealing plate 201, the cover plate 101 can be closed. As the cover plate 101 is closed, the telescopic rods 18 on the cover plate 101 will squeeze the pressure plate 17, and the test tube can be pressed against the support plate 3 through the pressure plate 17, thereby improving the stability during transportation and providing good protection for the test tube.
