Description

Technical Field

[0001] The utility model relates to the technical field of stem cells, in particular to a low-temperature storage device for stem cells. Background Art

[0002] Stem cells are a type of cell with unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. Currently, most biologists and medical scientists believe that stem cells are a type of cell that comes from embryos, fetuses or adults and has unlimited self-renewal, proliferation and differentiation capabilities under certain conditions. They can produce daughter cells with exactly the same phenotype and genotype as themselves, and can also produce specialized cells that make up the body's tissues and organs. At the same time, they can also differentiate into progenitor cells. Stem cells need to be stored at low temperatures to ensure their survival rate. However, existing stem cell low-temperature storage devices mostly use threaded sealing covers when in use, which are not easy to install and disassemble, affecting the storage speed. Utility Model Content

[0003] In view of this, the utility model provides a stem cell low-temperature storage device, which can be used by using the locking tongue on the top cover. The locking tongue enters the middle of the locking plate symmetrically arranged in the first groove by pressing the top cover. The bottom of the locking tongue is heart-shaped. When pressed, the locking tongue squeezes the locking plate, and the locking plate squeezes the first spring, thereby expanding the distance between the locking plates so that the locking tongue can fall downward. When the locking tongue is below the locking plate, the locking plate rebounds through the first spring and limits the locking tongue in the first groove. When the top cover needs to be opened, the pressing plate is pressed, and the pressing plate drives the connecting rod, and the connecting rod drives the push plate to move forward. The push rod pushes the locking tongue, and the locking tongue slides in the slide groove on the top cover. The locking tongue is pushed away from the first groove and pushed into the second groove by the push plate. The limit of the locking plate is released, and the top cover can be opened, so that the rapid installation and disassembly of the top cover can be completed, thereby accelerating the storage speed of the material.

[0004] In order to solve the above technical problems, the utility model provides a stem cell low-temperature storage device, including a box body, which is used to protect materials to a certain extent.

A first groove and a second groove are provided on the box body, and the first groove and the second groove are connected. A locking assembly is provided in the first groove, and the locking assembly is used to limit and fix the locking tongue.

[0005] The locking assembly includes a telescopic rod, which is used to allow the locking plate to have a certain movable space. The telescopic rod is symmetrically arranged on both sides of the first groove. A locking plate is connected to one end of the telescopic rod, and the locking plate is used to lock the lock tongue.

[0006] A first spring is sleeved on the telescopic rod, and the first spring is used to reset the telescopic rod. An opening is provided on one side of the first groove, and the opening is used to limit the pressing plate. A pressing plate is slidably provided in the opening, and the pressing plate is used to work in conjunction with the connecting rod.

[0007] A connecting rod is provided on the pressing plate, which is used to push the push plate to move. A push plate is connected to one end of the connecting rod, which is used to push the lock tongue to move. A second spring is sleeved on the connecting rod, which is used to reset the pressing plate to prevent the push plate from staying in the first groove, so that the lock tongue cannot be limited by the locking plate.

[0008] A square hole is provided on one side of the first groove, and the square hole is used to limit the push plate. The push plate is slidably arranged in the square hole. A sliding groove is provided on the top cover, and the sliding groove is used to limit the top cover. The lock tongue is slidably arranged in the sliding groove.

[0009] A liquid nitrogen pipeline is provided in the cryogenic chamber, which is used to store liquid nitrogen and reduce the temperature in the cryogenic chamber. A plurality of columns are provided on one side of the liquid nitrogen pipeline, on which a placement tray is slidably provided, and the columns are used to limit the placement tray, which is used to store materials.

[0010] Insulation cotton is provided on the other side of the liquid nitrogen pipeline and the top cover to prevent the cold air in the low-temperature chamber from escaping. A shoulder strap is connected to one side of the box to drive the box to move.
