[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1A schematic diagram of the structure of a cell freezing rack provided by the utility model; Figure 2 It is a structural schematic diagram of the slide plate and the frame of the utility model;

[0023] Figure 3 It is a structural schematic diagram of the slide plate and the slide column of the utility model; Figure 4 This is a structural schematic diagram of the fixing strip and card strip of the utility model; Figure 5 For this utility model Figure 4 The enlarged schematic diagram of the structure at A in the middle comprises a box body 1, and a door panel 2 is hinged on the box body 1, and a door lock structure (not shown in the figure) is arranged between the door panel 2 and the box body 1, which is used to close the door panel 2 on the box body 1.

[0024] A plurality of slide grooves 3 are provided on the inner walls on both sides of the box body 1, and a slide plate 4 is slidably connected between two corresponding slide grooves 3, and a frame 7 is fixedly connected to the upper surface of the slide plate 4, and the frame 7 is used to place the cryotube. The slide plate 4 is T-shaped, and a slide column 6 is fixedly connected to both sides of the slide plate 4, and the slide column 6 is slidably connected to the corresponding slide groove 3. When in use, the door panel 2 is opened, the slide plate 4 is pulled outward, and the slide column 6 slides inside the slide groove 3. When the slide column 6 moves to the end of the slide groove 3 close to the box opening of the box body 1, the slide plate 4 can be tilted downward with the two slide columns 6 as the axis, and the frame 7 is tilted downward synchronously, which is convenient for operators to take and place cryotubes, especially the slide plate 4 and frame 7 at a higher position.

[0025] In order to realize the positioning of the cryopreservation tube, square grooves 13 are provided on both side walls of the frame 7, and the end of the square grooves 13 close to the sliding column 6 is connected to the outside, and the inside of the square grooves 13 is slidably connected with a slide bar 14. Sliding channels 16 are provided on both side inner walls of the frame 7, and the sliding channels 16 are connected with the corresponding square grooves 13. A connecting block 17 is slidably connected inside the sliding channel 16, and a clamping bar 9 is fixedly connected between the two connecting blocks 17. A fixing bar 8 is provided on the side of the clamping bar 9 close to the opening of the box body 1, and the fixing bar 8 is fixedly connected to the inside of the frame 7 and is distributed parallel to the clamping bar 9. When in use, the cryopreservation tube is placed between the fixing bar 8 and the clamping bar 9.

[0026] A spring 15 is disposed inside the square groove 13 , one end of the spring 15 is fixedly connected to the inner wall of the square groove 13 , and the other end of the spring 15 is fixedly connected to the slide bar 14 .

[0027] When the slide plate 4 is pushed into the box 1, the frame 7 moves inward synchronously, and the slide bar 14 first abuts against the inner wall of the box 1, and the slide bar 14 is retracted into the square groove 13, and the connecting block 17 drives the clamping bar 9 to move toward the fixing bar 8, so as to realize the positioning of the cryopreservation tube and facilitate the transfer of the cell cryopreservation rack;

[0028] In this process, the spring 15 is squeezed and contracted, and the gravity of the slide bar 14 and the frame 7 is greater than the restoring elastic force of the spring 15, so the slide bar 14 and the frame 7 will not slide in the reverse direction.

[0029] In addition, when the door panel 2 is closed, the slide plate 4 can be positioned and the slide plate 4 will not slide out.

[0030] When the slide plate 4 is pulled out of the box body 1, the frame body 7 moves outward synchronously, the slide bar 14 is released from the squeezing of the inner wall of the box body 1, and the restoring elastic force of the spring 15 resets the slide bar 14, causing the clamping bar 9 to move in the direction away from the fixed bar 8. The distance between the clamping bar 9 and the fixed bar 8 is enlarged, making it easier to take out the cryotube.

[0031] The utility model provides structures such as a slide plate 4, a frame body 7, a square groove 13 and a slide bar 14, so that when the slide plate 4 is pushed into the box body 1, the freezing tube is positioned synchronously, which is convenient for transferring the cell freezing rack. When the slide plate 4 is pulled out of the box body 1, the distance between the clamping bar 9 and the fixing bar 8 is expanded, which is convenient for taking out the freezing tube.

[0032] During specific use, structures such as the fixing strips 8, the clamping strips 9, the sliding channels 16 and the connecting blocks 17 can be provided in multiple groups to place more cryotubes at the same time.

[0033] A first card slot 10 is provided on the side of the fixing strip 8 facing the card strip 9. The first card slot 10 is provided in plurality and the plurality of first card slots 10 are distributed at equal distances. A second card slot 11 is provided on the side of the card strip 9 facing the fixing strip 8. The second card slot 11 is provided in plurality and the plurality of second card slots 11 are distributed in one-to-one correspondence with the plurality of first card slots 10. In specific use, rubber pads are provided on the first card slot 10 and the second card slot 11 to avoid wear of the cryopreservation tube.

[0034] In order to improve the stability of the placement of the cryotube, a slot 12 is provided on the upper surface of the slide plate 4 . The slot 12 is provided in plurality and cooperates with the corresponding first card slot 10 and second card slot 11 .

[0035] During operation, the bottom end of the cryotube is inserted into the slot 12 , and the outer wall thereof abuts against the first slot 10 . When the clamping bar 9 moves toward the fixing bar 8 , the cryotube is clamped and positioned between the first slot 10 and the second slot 11 .

[0036] Two limit blocks 5 are arranged above the frame 7 . The two limit blocks 5 are fixedly connected to the inner walls on both sides of the box 1 , and the limit blocks 5 cooperate with the clamping strips 9 .

[0037] When it is necessary to take out the cryotube, the door panel 2 is opened, the slide plate 4 is pulled outward, and the slide column 6 slides inside the slide groove 3. After moving a certain distance, the slide bar 14 extends out from the inside of the square groove 13; when the slide column 6 moves to the end of the slide groove 3 close to the box opening of the box body 1, the slide plate 4 can be tilted downward with the two slide columns 6 as the axis, and the frame body 7 is tilted downward synchronously, and the slide bar 14 will abut against the limit block 5 to position the inclination angle of the slide plate 4 and the frame body 7, which is convenient for the operator to use.
