[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The stem cell classification storage device disclosed in the present invention is mainly used in scenarios where stem cell bottles stored in classification at low temperatures are prone to falling, and collisions can destroy the microenvironment inside the bottle and damage the activity of the stem cells.

[0030] The anti-drop assembly 10 is located inside the storage cabinet 1 and includes a drop basket located in front of the sliding plate 13. The anti-drop assembly 10 effectively prevents the cell storage tubes from falling due to low temperature when the staff takes the classified stored stem cells in the storage cabinet 1, thereby ensuring that the stem cell storage tubes are intact.

[0031] The symmetrical locking assembly 14 is located below the drop basket. The locking assembly 14 includes symmetrical locking pieces 1407. A plurality of symmetrical locking slots are provided at both ends of the inner side of the storage cabinet 1. The locking pieces 1407 are movably connected to the inner portions of the locking slots. The locking assembly 14 effectively fixes the drop basket 1006 to prevent the drop basket 1006 from falling due to gravity.

[0032] Auxiliary component 15, the auxiliary component 15 is located in front of the drop basket, the auxiliary component 15 includes a buffer plate 1504, the buffer plate 1504 is located above the front side of the drop frame 1006, and the side of the buffer plate 1504 away from the drop frame 1006 is fixedly connected to multiple buffer springs 1505. The auxiliary component 15 effectively causes the stem cell storage bottle to fall into the middle position of the drop basket.

[0033] Reference Figure 2 、 Figure 4 、 Figure 5 and Figure 6The anti-fall component 10 also includes a symmetrical drive motor 1001, and the outer side of the drive motor 1001 is fixedly connected to a fixed ring frame 1002, and the power output shaft of the drive motor 1001 is connected to a rotating shaft 1003 through a coupling, and the opposite side of the rotating shaft 1003 is movably connected to the two ends of the inner side of the storage cabinet 1, and the inner side of the rotating shaft 1003 is movably connected to a pulling rope 1004, and the bottom ends of the two pulling ropes 1004 are fixedly connected to a sliding member 1008, and the opposite side of the sliding member 1008 is fixedly connected to the two ends of the drop frame 1006, and both sides of the sliding member 1008 are movably connected to a slide plate 1005, and one side of the slide plate 1005 is fixedly connected to the inner two sides of the storage cabinet 1, and a circular hole is opened on the sliding member 1008. The inside of the hole is movably connected with a guide rod 1007, and the guide rod 1007 is located behind the pulling rope 1004. A plurality of rectangular holes are opened on the opposite sides of the two slide plates 1005 located on the same side. The inside of the rectangular hole is fixedly connected with a fixed rod 1009, and the outside of the fixed rod 1009 is movably connected with an elastic plate 1010. Both sides of the elastic plate 1010 are fixedly connected with a pressing part 1011. Both sides of the elastic plate 1010 are provided with a positioner 1012. The side of the positioner 1012 away from the elastic plate 1010 is fixedly connected to the two sides inside the storage cabinet 1. A symmetrical return spring 1013 is fixedly connected to the bottom of the elastic plate 1010, and the end of the return spring 1013 away from the elastic plate 1010 is fixedly connected to the two sides inside the storage cabinet 1.

[0034] Specifically, when the staff takes the classified stored stem cells, the driving motor 1001 is started, driving the rotating shaft 1003 to rotate. The rotation of the rotating shaft 1003 causes the pulling rope 1004 to be wrapped around its inner side. The pulling rope 1004 pulls the sliding member 1008 fixed at the bottom end. The sliding member 1008 slides upward along the guide rod 1007 in the slide plate 1005 (the guide rod 1007 plays a guiding role to ensure the smooth sliding of the sliding member 1008), thereby driving the drop frame 1006 to rise to catch the dropped storage bottle. During the rising process of the sliding member 1008, the elastic plate 1010 is driven to move upward, and the elastic plate 1010 rotates around the fixed rod 1009 (the fixed rod 1009 plays a role in supporting the rotation of the elastic plate 1010). During this process, the return spring 1013 is squeezed to store elastic potential energy. As the sliding member 100 8 continues to rise, the pressing member 1011 on the elastic plate 1010 contacts the positioner 1012, and the positioner 1012 triggers a signal, indicating that the drop frame 1006 has reached the specified position. At this time, the driving motor 1001 can stop working and maintain the current state, so that the drop frame 1006 is stable in this position to catch the dropped storage bottle. When there is no longer a risk of the storage bottle falling, the driving motor 1001 is reversed, the rotating shaft 1003 rotates in the opposite direction, and the rope 1004 is pulled to relax. Under the elastic restoring force of the reset spring 1013, the elastic plate 1010 drives the sliding member 1008 and the drop frame 1006 to move downward and return to the initial position. The reset spring 1013 returns to its natural extension state and waits for the next trigger. During the process, the dropped storage bottle is caught in time to avoid it from falling and being damaged directly, thereby ensuring the integrity and activity of the stem cell sample and preventing the storage bottle from breaking due to collision.

[0035] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The front end of the storage cabinet 1 is movably connected to a cabinet door 2, and the front end of the cabinet door 2 is fixedly connected to an observation window 3, and the front end of the cabinet door 2 is fixedly connected to a control panel 4, and the front end of the cabinet door 2 is fixedly connected to a handle 5, and the handle 5 is located on one side of the observation window 3. The front end of the cabinet door 2 is fixedly connected to a plurality of indicator lights 7, and the indicator lights 7 are located above the observation window 3 and the control panel 4. The outside of the storage cabinet 1 is fixedly connected to a constant temperature device 6, and the inside of the storage cabinet 1 is fixedly connected to a plurality of symmetrical slide seats 12, and the opposite sides of the symmetrical slide seats 12 are movably connected to sliding plates 13. The front ends of the plurality of sliding plates 13 are fixedly connected to a card plate 9, and the inside of the drop frame 1006 is fixedly connected to a sponge pad 11, and both ends of the guide rod 1007 are fixedly connected to a fixed seat 8, and the bottom end of the fixing ring frame 1002 is fixedly connected to the top of the fixed seat 8, and a through-hole is provided on the fixed seat 8 at the top, and the pulling rope 1004 is movably connected between the inside of the through-hole.

[0036] Reference Figure 4and Figure 7 The locking assembly 14 includes a telescopic electric rod 1401, and the outer side of the telescopic electric rod 1401 is fixedly connected to a fixing plate 1402, and the top of the fixing plate 1402 is fixedly connected to the bottom end of the drop frame 1006, and the front end of the telescopic electric rod 1401 is fixedly connected to a connecting plate 1405, and the connecting plate 1405 is located on one side of the fixing plate 1402 and is fixedly connected to the telescopic rod 1403, and the bottom end of the telescopic rod 1403 is fixedly connected to the front end of the fixing plate 1402, and a compression spring 1404 is provided on the outer side of the telescopic rod 1403, and the two ends of the compression spring 1404 are respectively fixedly connected to one side of the fixing plate 1402 and the connecting plate 1405, and the front end of the connecting plate 1405 is fixedly connected to a symmetrical connecting rod 1406, and the front end of the connecting rod 1406 is fixedly connected to the rear end of the locking member 1407.

[0037] Specifically, when the drop frame 1006 reaches the specified position, the telescopic electric rod 1401 begins to extend, pushing the connecting plate 1405 fixedly connected thereto to move forward, driving the telescopic rod 1403 to move synchronously, and the compression spring 1404 on the outside of the telescopic rod 1403 is compressed. The compression spring 1404 generates elastic force during the compression process, and works together with the telescopic rod 1403 to make the movement of the connecting plate 1405 and the connected parts more stable. When the connecting plate 1405 moves forward, the power is transmitted to the positioning member 1407, driving the positioning member 1407 to move toward the card slot hole of the storage cabinet 1. As the telescopic electric rod 1401 continues to extend, the connecting rod 1406 pushes the positioning member 1407 is precisely embedded in the card slot hole of the storage cabinet 1 to complete the fixation of the drop frame 1006 and prevent it from being displaced during use. When the drop frame 1006 needs to be moved, the telescopic electric rod 1401 contracts and the compression spring 1404 returns to its natural extended state. The elastic force generated pushes the connecting plate 1405 to move backward, and the connecting rod 1406 drives the locking piece 1407 to withdraw from the card slot hole, releasing the fixation of the drop frame 1006 so that the drop frame 1006 can be adjusted for the next position. During the process, the drop frame 1006 is firmly fixed to prevent shaking and displacement, ensure the stability when receiving the dropped stem cell storage bottle, and avoid secondary collision caused by the movement of the drop frame 1006.

[0038] Reference Figure 4 and Figure 8The auxiliary component 15 also includes a telescopic drive rod 1501, and the telescopic drive rod 1501 is fixedly connected to a retaining piece 1502 on the side close to the slide seat 12, and the top of the retaining piece 1502 is fixedly connected to the bottom end of the drop frame 1006, and the front end of the telescopic drive rod 1501 is fixedly connected to an inclined plate 1503, and the front end of the inclined plate 1503 is fixedly connected to the end of the buffer spring 1505 away from the buffer plate 1504, and the side of the inclined plate 1503 close to the drop frame 1006 is fixedly connected to a spring rod 1506, and the side of the spring rod 1506 away from the inclined plate 1503 is fixedly connected to a fixing piece 1507, and the top of the fixing piece 1507 is fixedly connected to the bottom end of the drop frame 1006.

[0039] Specifically, when several cell storage bottles fall on the edge of the drop frame 1006, a lateral impact force is generated on the buffer plate 1504. The storage bottles hit the buffer plate 1504, and the buffer plate 1504 transmits the impact force to the buffer spring 1505 connected thereto. The buffer spring 1505 is compressed and deformed under the force, absorbing part of the impact force of the storage bottles, playing a buffering and shock-absorbing role, and preventing the storage bottles from being damaged due to hard collisions. During the compression process of the buffer spring 1505, the oblique plate 1503 is pushed. The oblique plate 1503 is fixedly connected to the front end of the telescopic drive rod 1501, driving the telescopic drive rod 1501 to move. The telescopic drive rod 1501 is telescopically adjusted according to the force conditions to adapt to the buffer plate 150 4 changes in position. During the movement of the oblique plate 1503, the spring rod 1506 connected thereto will also undergo corresponding elastic deformation. One end of the spring rod 1506 is connected to the oblique plate 1503, and the other end is connected to the bottom end of the drop frame 1006 through the fixing piece 1507. It can assist the oblique plate 1503 in adjusting the position and angle, making the movement of the buffer plate 1504 more stable and accurate. While absorbing the impact force, the buffer plate 1504 pushes the storage bottle to the middle position of the drop frame 1006. With the elastic recovery of the buffer spring 1505 and the linkage adjustment of various components, the stem cell storage bottle that has fallen to the edge is finally moved to the middle position of the drop frame 1006, ensuring that the storage bottle is properly placed.

[0040] A method for using a stem cell classification storage device, using the stem cell classification storage device as described above, comprises the following steps:

[0041] Step 1: Since the stem cell classification storage device is in a low-temperature environment for a long time, when the staff member takes a large number of stem cell storage bottles, their hands are easily affected by the low temperature, causing the storage bottles to slip. At this time, when the staff member needs to store and retrieve stem cells at a specific location in the storage cabinet 1, the anti-drop component 10 will move the drop frame 1006 to the corresponding position and stand by. Once the storage bottle falls, it will fall directly into the drop frame 1006;

[0042] Step 2: The locking assembly 14 will insert the locking pieces 1407 on both sides into the slots inside the storage cabinet 1 to firmly fix the drop frame 1006 to prevent the drop frame 1006 from moving downward due to gravity;

[0043] Step 3: If a stem cell storage bottle falls on the edge of the drop frame 1006, the buffer plate 1504 in the auxiliary component 15 can use the elasticity of the buffer spring 1505 to bounce the slipped storage bottle to the center of the drop frame 1006, further ensuring the safety of the storage bottle.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
