Description

Stem cell low-temperature refrigerator Technical Field The utility model relates to the technical field of low-temperature refrigerators, in particular to a stem cell low-temperature refrigerator. Background The low-temperature refrigerator is used for transporting stem cells and consists of a refrigerator body, a refrigerator cover, an ice box, a thermometer and a storage box, when the low-temperature refrigerator is used, ice crystal powder and water are added into the ice box, then the ice box is placed into a freezing chamber for freezing, the ice box is placed into the refrigerator body after being frozen, then the storage box is placed into the storage box, then a test tube filled with the stem cells is placed into a mounting groove in the storage box, then the ice box on the top layer is covered, finally a cover is covered, the lower end of the cover is provided with a sealing ring sealed with the refrigerator body, and the temperature in the refrigerator body can be detected through the thermometer. The inventor finds that when the low-temperature refrigerator is used in daily work, the test tube with stem cells is inserted into the mounting groove on the storage box, and the mounting groove is lack of a mechanism for limiting the test tube, so that the test tube is jolt in the transportation process, and is rocked, so that the test tube collides with the inside of the low-temperature refrigerator, and further the test tube is likely to be broken. Disclosure of utility model The utility model aims to solve the problem that in the actual use process, a test tube filled with stem cells is inserted into a mounting groove on a storage box, and a mechanism for limiting the test tube is lacking in the mounting groove, so that the test tube is jolt in the transportation process, and is rocked to collide with the inside of a low-temperature refrigerator, and the test tube is likely to be broken. In order to achieve the aim, the stem cell low-temperature refrigerator comprises a box body and a box cover, wherein the inner wall of the box body is provided with a bottom ice box, a top ice box and a side ice box, the front surface of the box body is provided with a thermometer which is used for detecting the temperature in the box body, the upper end of the bottom ice box is provided with a storage box, the upper end of the storage box is provided with a fixing component, the fixing component comprises an annular groove which is formed in the inner wall of the storage box, the inner wall of the annular groove is provided with an annular air bag, and rubber clamping blocks are fixedly connected to two sides of an inner arc surface of the annular air bag. The fixing assembly has the advantages that when the test tube filled with the stem cells in the mounting groove of the storage box needs to be fixed, the annular air bag in the annular groove is bulged through the air inlet mechanism, so that the rubber clamping block is pushed to clamp and fix the test tube, and the effect of fixing the test tube filled with the stem cells is achieved as much as possible. Preferably, the inside of depositing the case has seted up the air cavity, fixedly connected with trachea between air cavity and the annular gasbag, the operation groove has been seted up to the upper end of depositing the case, the inner wall bottom screw thread of operation groove inserts and is equipped with the lead screw, the lower extreme of lead screw rotates and is connected with the piston. The screw rod is screwed to enable the piston to descend, so that gas in the air cavity is pushed by the piston to flow to the annular air bag through the air pipe, and the annular air bag in the annular groove bulges.
