Description

Technical Field

[0001] This invention belongs to the field of cell cryobox technology, and in particular relates to a cryobox that facilitates the removal of cells. Background Technology

[0002] Cell cryopreservation is a device used for low-temperature preservation of cells. Cell cryopreservation can reduce cell metabolism, store cells for a long time, play a role in cell seed preservation, and facilitate the purchase, donation, exchange and transportation of cells. Cell cryopreservation and thawing follow the principle of slow freezing and rapid thawing. Glycerol or dimethyl sulfoxide is often used as a protective agent. Slow freezing causes water to seep out of the cells, reduces the formation of ice crystals and avoids cell damage.

[0003] Cells stored in cell cryo-boxes are usually placed in containers. The placement trays inside the cryo-box are generally fixed. When taking out cells from the inside, the cell containers are easily damaged by collision, and there is also a possibility that the cell containers on the outside may be knocked off. Therefore, we designed a cryo-box that makes it easier to take out cells. The placement tray has a concave design, which makes it less likely to fall off. With the help of a pull-out structure, the placement tray can be pulled to the outside of the cryo-box to take out cells, making it convenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a cryobox that facilitates cell retrieval. It features a concave placement tray that is less prone to falling, and a pull-out structure that allows the tray to be pulled to the outside of the cryobox for easy cell retrieval, thus solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A cryobox for easy cell removal includes a cryobox body. Multiple support plates are fixedly connected to the inner cavity of the cryobox body. A movable tray is provided on the top of each support plate. A sleeve is fixedly installed on both sides of the top of each support plate. Tracks that slide within the inner cavity of the sleeves are fixedly connected to both sides of the tray. Anti-detachment blocks are provided at the ends of the inner cavities of the tracks. An movable cavity for the anti-detachment blocks is opened in the inner cavity of the sleeve. A limiting baffle adapted to the anti-detachment blocks is provided at the end of the inner cavity of the movable cavity. Two symmetrical insertion holes are opened on the sleeve. Screws are inserted into the inner cavities of the insertion holes. Two symmetrical threaded holes are opened on both sides of the top of each support plate. The screws pass through the insertion holes and are threadedly connected to the threaded holes.

[0006] Preferably, two symmetrical positioning pins are fixedly connected to both sides of the top of the support plate, and two positioning holes that are adapted to the positioning pins are opened at the bottom of the sleeve.

[0007] Preferably, the bottom of the inner cavity of the storage tray and the top of the support plate are provided with multiple prismatic holes.

[0008] Preferably, the front side of the freezer is hinged with a door, and an observation window is provided through the door.

[0009] Preferably, a push-down door handle is installed between the freezer body and the door.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model, by installing the housing on the support plate, can limit the tracks on both sides of the tray to the top of the support plate, and then the tray can be pulled out from the top of the support plate to the outside of the freezer for easy access to the cells inside. The edge of the tray is designed to prevent it from falling. The concave design of the tray makes it less likely to fall, and the pull-out structure allows the tray to be pulled to the outside of the freezer for easy access to the cells.

[0012] 2. This utility model, through the setting of anti-detachment block, movable cavity and limiting baffle, can limit the storage tray. During the process of pulling out the storage tray, the limiting baffle can block the anti-detachment block and prevent the storage tray from being completely pulled away from the top of the support plate.

[0013] 3. The design of this utility model, through the setting of the rhomboid holes, allows the cold air inside the freezer to enter the storage tray through the rhomboid holes, ensuring that the cells stored in the storage tray are frozen more evenly.

[0014] 4. By using the positioning pin and positioning hole together, when the housing is placed on the support plate during installation, the positioning hole on the housing fits onto the surface of the positioning pin on the support plate, which facilitates the alignment of the insertion hole on the housing with the threaded hole on the support plate.

[0021] In the following description, embodiments of the cryobox for easy cell removal according to the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-3 This invention illustrates a cryostat for easy cell removal according to an embodiment of the present invention. It includes a cryostat body 1, with multiple support plates 2 fixedly connected to the inner cavity of the cryostat body 1. A movable tray 3 is provided on the top of each support plate 2. Multiple prismatic holes 15 are provided at the bottom of the inner cavity of the tray 3 and at the top of the support plates 2. These prismatic holes 15 allow cold air from the cryostat body 1 to enter the tray 3, ensuring that the cells stored in the tray 3 receive relatively uniform cooling. The support plate 2 has a sleeve 4 fixedly installed on both sides of its top. The storage tray 3 has a track 5 fixedly connected to both sides of the track 4, which slides within the inner cavity of the sleeve 4. An anti-detachment block 6 is provided at the end of the inner cavity of the track 5. The inner cavity of the sleeve 4 has a movable cavity 7 for the anti-detachment block 6 to move. A limiting baffle 8 adapted to the anti-detachment block 6 is provided at the end of the movable cavity 7. Through the anti-detachment block 6, the movable cavity 7, and the limiting baffle 8, the storage tray 3 is effectively limited during the pulling process of the storage tray 3. The limiting baffle 8 can block the anti-detachment block 6, preventing the tray 3 from being completely pulled away from the top of the support plate 2. Two symmetrical insertion holes 10 are provided on the casing 4, and screws 11 are inserted into the inner cavity of the insertion holes 10. A door 16 is hinged to the front side of the freezer body 1, and an observation window 17 is provided through the door 16. A push-down door handle 9 is installed between the freezer body 1 and the door 16. Two symmetrical threaded holes 12 are provided on both sides of the top of the support plate 2, and screws 11 pass through the insertion holes 10 and... The support plate 2 is threadedly connected to the threaded hole 12. Two symmetrical positioning pins 13 are fixedly connected to both sides of the top. The bottom of the sleeve 4 has two positioning holes 14 that are adapted to the positioning pins 13. Through the cooperation of the positioning pins 13 and the positioning holes 14, when the sleeve 4 is installed on the support plate 2, the positioning holes 14 on the sleeve 4 fit onto the surface of the positioning pins 13 on the support plate 2, which facilitates the alignment of the insertion hole 10 on the sleeve 4 with the threaded hole 12 on the support plate 2.

[0023] Working principle: When using this utility model, the user observes the location of the cells to be retrieved through the observation window 17, then opens the cabinet door 16 by pressing down the door handle 9, and pulls out the tray 3 containing the cells to be retrieved, reducing search time and thus reducing the dissipation of cold air inside the freezer 1. When the tray 3 is pulled outward, it drives the track 5 to slide on the shell 4 until the tray 3 slides to its limit. At this time, the anti-detachment block 6 on the tray 3 contacts the limiting baffle 8 on the shell 4, preventing the tray 3 from completely detaching from the top of the support plate 2, so that the cells in the tray 3 can be quickly retrieved, avoiding collisions between cell containers.

[0024] In summary, this cell-removal-friendly freezer, with its casing 4 mounted on the support plate 2, allows the tracks 5 on both sides of the placement tray 3 to be positioned at the top of the support plate 2. This enables the placement tray 3 to be pulled out from the top of the support plate 2, allowing for easy access to cells inside the freezer. The edge-enclosed design of the placement tray 3 prevents it from falling, achieving the goal of convenient cell retrieval. The concave design of the placement tray further enhances its durability. Combined with the pull-out mechanism, the placement tray can be pulled to the outside of the freezer for easy cell retrieval.
