[0031] The specific settings and functions of the thermal insulation structure 3 and the limiting structure 4 are described in detail below.

[0032] Reference Figure 2 and Figure 3 As shown, in this embodiment: the heat preservation structure 3 includes a rectangular frame 301, two extension plates 302 are fixedly connected to the surface of the rectangular frame 301, and a latch 303 is slidably penetrated on the surface of the extension plate 302.

The size of the circular grooves 305 is adapted to the size of the latch 303, and heat preservation cotton 306 is placed on the inner wall of the rectangular box 304. The inner wall of the rectangular box 304 is threadedly connected with a threaded rod 307, and the surface of the threaded rod 307 is rotatably connected with a bracket 308. The bracket 308 will squeeze the heat preservation cotton 306 with the help of the threaded rod 307 until the heat preservation cotton 306 is tightly attached to the inner wall of the rectangular box 304, thereby improving the fit between the heat preservation cotton 306 and the inner wall of the rectangular box 304, and then facilitating the heat preservation cotton 306 to be fixed on the surface of the freezing box body 1. A rectangular groove 309 is provided on one side of the rectangular frame 301 near the rectangular box 304. The size of the rectangular groove 309 matches the size of the rectangular box 304. The edge of the rectangular box 304 will slide into the rectangular groove 309. The rectangular groove 309 improves the airtightness of the rectangular box 304 and the rectangular frame 301 when they are fitted together, thereby improving the insulation effect of the thermal insulation cotton 306. The arc surface of the latch 303 is covered with a first spring 310. The two ends of the first spring 310 are fixedly connected to the latch 303 and the extension plate 302 respectively. The latch 303 will be inserted into the circular groove 305 with the help of the contraction force of the first spring 310. The first spring 310 improves the stability of the latch 303 inserted into the circular hole and prevents the latch 303 from falling out of the circular hole.

[0033] Reference Figure 4 and Figure 5 and Figure 6As shown, specifically, the limiting structure 4 includes a plurality of second springs 41, and the plurality of second springs 41 are fixedly connected to the inner wall of the placement slot 2, and the other ends of the plurality of second springs 41 are fixedly connected to a pressure plate 42. A guide slot 43 is provided on the inner wall of the placement slot 2, and a guide plate 44 is slidably connected to the inner wall of the guide slot 43, and the guide plate 44 is fixedly connected to one side of the pressure plate 42. When the pressure plate 42 moves, it will drive the guide plate 44 to slide along the inner wall of the guide slot 43, and the guide slot 43 can limit the moving path of the guide plate 44, thereby avoiding the displacement of the pressure plate 42 when moving, and thus improving the effect of the guide plate 44 limiting the position of the test tube.

The test tube will fit on the protective pad 45 on the surface of the pressure plate 42, and the protective pad 45 can further reduce the occurrence of test tube damage.

[0034] Working principle: when it is necessary to add an insulation layer to the surface of the freezing box body 1, first rotate the threaded rod 307. The rotation of the threaded rod 307 will move in the rectangular box 304 with the help of the thread. The movement of the threaded rod 307 will drive the bracket 308 to move. After the threaded rod 307 is disengaged from the rectangular box 304, the bracket 308 is taken out of the rectangular box 304, and then the insulation cotton 306 is attached to the rectangular box 304, and then the bracket 308 is placed in the rectangular box 304. At this time, the bracket 308 will be attached to the surface of the insulation cotton 306, and the threaded rod 307 will pass through the insulation cotton 306. Then rotate the threaded rod 307. The threaded rod 307 will be used in the rectangular box 304 with the help of the thread. The bracket 308 will squeeze the insulation cotton 306 with the help of the movement of the threaded rod 307 until the insulation cotton 306 is tightly attached to the inner wall of the rectangular box 304, and pull the latch 303. The latch 303 will When sliding in the extension plate 302, the latch 303 will stretch the first spring 310 when moving. At this time, the first spring 310 is in a stretched state. When the latch 303 moves to a suitable position, the rectangular box 304 is put on the surface of the freezing box body 1. The rectangular box 304 will drive the thermal insulation cotton 306 to fit tightly to the surface of the freezing box body 1. At this time, the rectangular box 304 will fit on the surface of the rectangular frame 301. The edge of the rectangular box 304 will slide into the rectangular groove 309. The rectangular groove 309 can improve the airtightness of the rectangular box 304 and the rectangular frame 301 when they are fitted, thereby improving the thermal insulation effect of the thermal insulation cotton 306. Then the latch 303 is released. The latch 303 will be inserted into the circular groove 305 with the help of the contraction force of the first spring 310. The latch 303 reaches the position to limit the rectangular box 304, thereby limiting the rectangular box 304 to the surface of the freezing box body 1.

[0035] When it is necessary to place the test tube containing stem cells into the placement slot 2, first place the test tube into the placement slot 2, press the test tube, and the test tube will fit on the protective pad 45 on the surface of the pressure plate 42. The test tube will squeeze the pressure plate 42 when moving, and the pressure plate 42 will be compressed by the test tube, which will cause the second spring 41 to be compressed. When moving, the pressure plate 42 will drive the guide plate 44 to slide along the inner wall of the guide slot 43. The guide slot 43 limits the moving path of the guide plate 44, thereby avoiding the displacement of the pressure plate 42 when moving, thereby improving the effect of the guide plate 44 on limiting the test tube. When the test tube is fully inserted into the placement slot 2, the pressure plate 42 will use the elastic force of the second spring 41 to squeeze the test tube tightly into the placement slot 2, thereby improving the stability of the test tube inserted into the placement slot 2.
