At the same time, the semen tube can be limited by the carrier component, so that the semen tube can be stably placed in the box body 2, which can effectively avoid damage to the semen tube.

[0025] In a further optimized solution, the bottom surface of the liquid nitrogen tank 10 is connected to the box body 2 through a pipe, and one end of the pipe extending into the box body 2 is arranged at the lower part of the side wall of the box body 2. A solenoid valve is installed at one end of the pipe close to the liquid nitrogen tank 10, and the solenoid valve is electrically connected to the controller 7. The opening and closing of the solenoid valve is controlled by the controller 7 to control the liquid nitrogen to enter the box body 2.

The step groove 21 and the step block can effectively abut the top cover 5 against the box body 2, thereby preventing the cold air in the box body 2 from escaping and effectively increasing the sealing between the top cover 5 and the box body 2; at the same time, the handle 9 makes it easy to move the box body 2.

[0027] In a further optimized solution, a sealing gasket is fixedly connected in the stepped groove 21. By providing the sealing gasket, the sealing performance between the top cover 5 and the box body 2 can be increased.

[0028] Further optimized solution, the lifting assembly includes positioning plates 33 symmetrically arranged on the upper part of the inner wall of the box body 2, the bottom surface of one positioning plate 33 is rotatably connected with a lead screw 3, the lead screw 3 is threadedly connected with a first slider 32, one end of the lead screw 3 that passes through the bottom surface of the box body 2 is transmission-connected with a motor 31, the motor 31 is fixedly connected to the box body 2, the bottom surface of the other positioning plate 33 is fixedly connected with one end of a limit rod 34, the other end of the limit rod 34 is fixedly connected to the bottom of the box body 2, the limit rod 34 is slidably connected with a second slider 35, the first slider 32 and the second slider 35 are arranged on the same horizontal plane, the opposite side of the first slider 32 and the second slider 35 is fixedly connected to the object-carrying assembly, and the motor 31 is electrically connected to the controller 7. The motor 31 drives the lead screw 3 to rotate, and the rotation of the lead screw 3 can drive the first slider 32 to move up and down along the lead screw 3, so that the second slider 35 can move up and down along the limit rod 34, so that the object-carrying assembly can move downward following the first slider 32 and the second slider 35.

[0029] In a further optimized solution, the object-carrying assembly includes symmetrically arranged connecting plates 42, two connecting plates 42 are respectively fixedly connected to the first slider 32 and the second slider 35, and the two connecting plates 42 are fixedly connected to the upper supporting plate 4 and the lower supporting plate 41 on opposite sides. The upper supporting plate 4 is arranged above the lower supporting plate 41, and the top and bottom surfaces of the connecting plates 42 are fixedly connected to the temperature detector 8, which is electrically connected to the controller 7. A gap is left between the upper supporting plate 4 and the lower supporting plate 41 to facilitate the circulation of cold air, so that the semen tube is in the cold air, and the semen is effectively stored at low temperature.

[0030] In a further optimized solution, the top surface of the upper support plate 4 is provided with a plurality of through holes 43, and the side of the lower support plate 41 facing the upper support plate 4 is provided with a plurality of limiting holes 45, and the through holes 43 and the limiting holes 45 are provided one by one.

[0032] In order to prevent the motor 31 from bumping into something, the height of the support column 1 is greater than the height of the motor 31, so that when the box 2 is placed on the ground, the motor 31 does not bump into the ground, effectively preventing the motor 31 from being damaged by collision with the ground.

[0033] Reference Figure 5 , several boxes 2 can be stacked, the support columns 1 and the positioning tubes 11 are arranged one by one, and the diameter of the support columns 1 is not larger than the inner diameter of the positioning tube 11, so that the support columns 1 can be smoothly inserted into the positioning tube 11; when stacking is required, one box 2 is placed so that the support column 1 of this box 2 is in contact with the ground, and then the support column 1 of another box 2 is inserted into the positioning tube 11 on the top cover 5 below, and then stacking can be carried out, which effectively avoids the waste of storage space.

The low-temperature resistant silicone rubber 44 can squeeze the semen tube to prevent the semen tube from shaking and causing damage in the through hole 43 and the limiting hole 45; after placing the semen tube, install the top cover 5 on the box body 2 through the buckle 6, and open the solenoid valve through the controller 7 to allow the nitrogen in the liquid nitrogen tank 10 to flow into the box body 2, so that the box body 2 is in a low-temperature state. When the controller 7 receives the temperature feedback from the temperature detector 8, the controller 7 controls the motor 31 to drive the screw 3 to rotate The lead screw 3 drives the first slider 32 to move up and down, so that the upper support plate 4 and the lower support plate 41 are in a suitable temperature range, so that the semen tubes can be in a suitable low-temperature environment, and the semen tubes containing semen can be effectively and safely stored at low temperatures. The controller 7 is electrically connected to a signal module, and the signal module is used to transmit and receive signals, so that the controller 7 can be remotely operated and the temperature in the box 2 can be remotely monitored; in order to prevent the battery from running out of power during the storage process, when the box 2 is equipped with the semen tubes and the box 2 is placed in the designated position, the battery charging port is connected to the mains.
