[0010] Compared with the prior art, the beneficial effects of this utility model are: the stem cell cryopreservation tube anti-tipping placement and fixing frame not only supports the cryopreservation tube to improve its stability and can automatically push out the cryopreservation tube, but also can automatically control the opening and closing of the cover plate. (1) By setting up a mounting bracket, a fixing ring, a lifting plate, a fixing groove and a rubber pad, when placing the cryopreservation tube, the cryopreservation tube is inserted into the inside of the fixing ring from the top, so that it passes through the inside of the fixing ring and then is inserted into the inside of the fixing groove. The fixing groove and the fixing ring can support the cryopreservation tube to ensure its stability. The rubber pad inside the fixing groove can play a buffering and anti-slip role to prevent the cryopreservation tube from vibrating, thereby improving the stability of the cryopreservation tube after placement. This achieves effective support for the cryopreservation tube and improves its stability. (2) By setting up a movable groove, lifting plate, fixed column, limit sleeve, spring, connecting plate, spring piece, positioning block and positioning slot, when the cryopreservation tube needs to be taken out, after opening the protective cover, rotate the placement frame to find the required cryopreservation tube, press the positioning block at the corresponding position to make it disengage from the inside of the positioning slot, and the spring inside the mounting frame drives the lifting plate to rise through the limit sleeve. At the same time as the lifting plate rises, it can lift the cryopreservation tube at the top through the fixed slot. Lifting the cryopreservation tube makes it easy to take out the cryopreservation tube. The fixed column is attached to the inside of the limit sleeve to limit the lifting plate and ensure its stability, thus realizing that the cryopreservation tube can be automatically pushed out. (3) By setting up a protective cover, a fixed sleeve, a control panel, a lifting groove, a connecting plate and a cylinder, after the cryopreservation tube is placed, the cylinder inside the support cylinder is started by the control panel. After the cylinder is started, the fixed sleeve and the protective cover are lowered by the connecting plate until the protective cover is placed on the top of the placement frame. At the same time, the protective cover will push the cryopreservation tube to lower the lifting plate so that it fits against the bottom of the placement frame. At the same time, the spring will push out the positioning card block so that it engages with the positioning card slot to position the lifting plate. When the cryopreservation tube needs to be removed, the cylinder is started again to lift the protective cover by the cylinder, thus realizing automatic control of the opening and closing of the protective cover.

The fixing groove 12, together with the fixing ring 4, can support the cryopreservation tube and ensure its stability. The rubber pad 13 inside the fixing groove 12 can play a buffering and anti-slip role, prevent the cryopreservation tube from vibrating, and improve the stability of the cryopreservation tube after placement. This achieves effective support for the cryopreservation tube and improves its stability.

[0015] Eight sets of fixed posts 11 are fixedly connected to the bottom of the placement frame 2. The top of the lifting plate 10 is fixedly connected to the limit sleeve 14. The top of the limit sleeve 14 is fixedly connected to the spring 15. Eight sets of movable grooves 9 are fixedly connected inside the placement frame 2. The movable grooves 9 are movably connected to the connecting sleeve 18. The top of the connecting sleeve 18 is fixedly connected to the spring piece 19. The bottom of one side of the spring piece 19 is fixedly connected to the positioning block 20. Eight sets of positioning slots 21 are opened at the bottom of the outside of the placement frame 2. The positioning block 20 is movably connected to the positioning slot 21, the connecting sleeve 18 passes through one side of the movable slot 9 and is fixedly connected to the lifting plate 10, the fixing column 11 passes through the limiting sleeve 14 and is fixedly connected to the mounting bracket 3, and the spring 15 is fixedly connected to the mounting bracket 3. Specifically, such as Figure 1 and Figure 4 As shown, when the cryopreservation tube needs to be removed, after opening the protective cover 5, rotating the placement frame 2 to find the required cryopreservation tube, pressing the positioning block 20 at the corresponding position to disengage it from the inside of the positioning slot 21, the spring 15 inside the mounting bracket 3 drives the lifting plate 10 to rise through the limiting sleeve 14. At the same time as the lifting plate 10 rises, it can lift the cryopreservation tube at the top through the fixing slot 12. Lifting the cryopreservation tube makes it easy to take it out. The fixing column 11 fits inside the limiting sleeve 14 to limit the lifting plate 10 and ensure its stability, thus realizing the automatic ejection of the cryopreservation tube.

[0016] Fixed sleeves 6 are movably connected to both ends of the support cylinder 1. A protective cover 5 is fixedly connected to the bottom end of the fixed sleeve 6. A set of lifting grooves 8 are opened at the top and bottom of both ends of the support cylinder 1. Cylinders 17 are fixedly connected to both ends inside the support cylinder 1.

The control panel 7 is electrically connected to the cylinder 17, the connecting plate 16 passes through the lifting groove 8 and is fixedly connected to the fixed sleeve 6, and the protective cover 5 is movably connected to the placement frame 2. Specifically, such as Figure 1 and Figure 2 As shown, after the cryopreservation tube is placed, the cylinder 17 inside the support cylinder 1 is activated by the control panel 7. After the cylinder 17 is activated, it drives the fixed sleeve 6 and the protective cover 5 to descend through the connecting plate 16 until the protective cover 5 covers the top of the placement frame 2. At the same time, the protective cover 5 pushes the cryopreservation tube to lower the lifting plate 10 so that it fits against the bottom of the placement frame 2. Meanwhile, the spring piece 19 pushes out the positioning block 20 so that it engages with the positioning slot 21 to position the lifting plate 10. When the cryopreservation tube needs to be removed, the cylinder 17 is activated again to lift the protective cover 5, thus realizing automatic control of the opening and closing of the protective cover 5.

[0017] Working Principle: In use, the cryopreservation tube is inserted into the fixing ring 4 from the top, passing through the fixing ring 4 and then into the fixing groove 12. The fixing groove 12, together with the fixing ring 4, supports the cryopreservation tube to ensure its stability. The rubber pad 13 inside the fixing groove 12 provides cushioning and anti-slip effects, preventing vibration of the cryopreservation tube and improving its stability after placement. After placing the cryopreservation tube, the cylinder 17 inside the support cylinder 1 is activated via the control panel 7. After the cylinder 17 is activated, it drives the fixing sleeve 6 and the protective cover 5 to descend via the connecting plate 16 until the protective cover 5 covers the top of the placement frame 2. At the same time, the protective cover 5 pushes the cryopreservation tube, causing the lifting plate 10 to descend and fit against the bottom of the placement frame 2. At the same time, the spring 19 pushes out the positioning block 20 so that it engages with the positioning slot 21 to position the lifting plate 10. When it is necessary to remove the cryopreservation tube, the cylinder 17 is activated to lift the protective cover 5. When it is necessary to remove the cryopreservation tube, the protective cover 5 is opened, the placement frame 2 is rotated to find the required cryopreservation tube, and the positioning block 20 at the corresponding position is pressed to disengage it from the inside of the positioning slot 21. The spring 15 inside the mounting frame 3 drives the lifting plate 10 to rise through the limiting sleeve 14. When the lifting plate 10 rises, it can lift the cryopreservation tube at the top through the fixing slot 12. Lifting the cryopreservation tube makes it easy to take it out. The fixing column 11 is attached to the inside of the limiting sleeve 14 to limit the lifting plate 10 and ensure its stability.
