The utility model discloses an embodiment, as shown in fig. 2, fig. 4 and fig. 8, be equipped with on the inboard diapire of thermal insulation box 1 with separate the joint groove 191 of cold box 5's lower extreme adaptation extrusion joint, separate the lower extreme adaptation extrusion joint of cold box 5 in joint groove 191, and the frictional force that the extrusion formed between the lower extreme of joint groove 191 and separate cold box 5 is less than the pulling force that the stay cord structure 50 produced to separate cold box 5 when pulling stay cord structure 50. In this embodiment, with the lower extreme adaptation extrusion joint of cold box body in joint groove 191, and the pull force of stay cord structure 50 to keeping apart cold box body 5 production when the frictional force that the extrusion formed is less than pulling stay cord structure 50 between joint groove 191 and the lower extreme that keeps apart cold box body 5, accessible extrusion down keeps apart cold box body 5 makes the lower extreme and the joint groove 191 joint that keeps apart cold box body 5, is convenient for cover continuous cold source bottle 4 and keep apart continuous cold source bottle 4 and stem cell storage area 17 on continuous cold source bottle 4 with keeping apart cold box body 5.

In one embodiment of the present invention, the pull cord structure 50 is a steel wire string. In this embodiment, adopt the steel wire string as stay cord structure 50, can reduce the size of the through-hole 23 that needs to set up, reduce at very big degree because the setting is used for through-hole 23 through stay cord structure 50 and the cold energy loss that causes, moreover, when steel wire string or other stay cord structures 50 passed through-hole 23, through-hole 23 can be blockked up to stay cord structure 50, the cold energy loss that produces from through-hole 23 is very little, can ignore for the influence of external environment temperature to the temperature environment in the cavity.

In an embodiment of the present invention, as shown in fig. 2, 4 to 6, a closed loop step groove is provided inside the open edge of the thermal insulation box body 1, and the thermal insulation sealing box cover 2 is provided with a closed loop protrusion 22 adapted to the closed loop step groove over the closed loop step groove; the stem cell cryogenic storage and transportation tank further comprises:

the elastic sealing ring 16 and the elastic sealing ring 16 are detachably arranged on the closed-loop step groove, and when the thermal insulation sealing box cover 2 is covered on the thermal insulation box body 1, the closed-loop bulge 22 is extruded on the elastic sealing ring 16 and enables the elastic sealing ring 16 to generate elastic deformation.

In this embodiment, as shown in fig. 2 and fig. 4 to fig. 6, a closed-loop step groove is provided on the inner side of the open edge of the thermal insulation box 1, the thermal insulation sealing box cover 2 is provided with a closed-loop protrusion 22 which is adapted to the closed-loop step groove over the closed-loop step groove, and the elastic sealing ring 16 is installed on the closed-loop step groove, when the thermal insulation sealing box cover 2 is covered on the thermal insulation box 1, the closed-loop protrusion 22 is extruded on the elastic sealing ring 16 and makes the elastic sealing ring 16 generate elastic deformation, thereby improving the sealing effect between the thermal insulation sealing box cover 2 and the thermal insulation box 1.

In addition, except the technical scheme that this embodiment is disclosed, to the utility model provides a coolant, cold source bottle 3, continuous cold source bottle 4, elasticity sealing washer 16 etc. can refer to this technical field's conventional technical scheme, and these conventional technical scheme also are not the utility model discloses a key, the utility model discloses do not state in detail here.
