They are usually used in biotechnologies such as artificial insemination or in vitro fertilization to achieve commercial applications of fish reproduction. In order to prolong the activity of fish sperm during storage, liquid tanks are needed for preservation.

[0003] In the prior art, such as publication number CN219330541U, a liquid nitrogen tank for storing fish sperm is disclosed, which includes a tank body, a rotating disk that can rotate is provided at the bottom of the tank body cavity, and a rotating bolt is fixedly installed at the middle position of the top of the rotating disk. The end of the rotating bolt away from the rotating disk passes through the top of the tank body and extends to the outside of the tank body. The utility model has the function of being able to classify and store fish sperm, and when taking a certain fish sperm, by twisting the rotating bolt, the mark on the rotating bolt is aligned with the position of the opening, so that one of the storage tanks storing fish sperm is located directly below the opening, and then the cover body is opened, and the hydraulic rod corresponding to the storage tank is controlled. The telescopic end of the hydraulic rod drives the storage tank to move upward in the tank body through the connecting rod, so that the two fixed rods on the side wall of the storage tank move along the two positioning rods, and the top of the storage tank extends out of the opening. Finally, the sealing cover on the top of the storage tank is twisted to take out the fish sperm stored in the storage tank.

[0004] However, this device still has some problems. The liquid tank not only needs to meet the low-temperature storage requirements for fish sperm, but also needs to be transported and carried during actual use. During transportation, the sperm tank will shake due to external forces and may be bumped, causing damage to the sperm tank. Therefore, we disclose a liquid nitrogen tank for storing fish sperm to meet people's needs. Utility Model Content

At the same time, the placement plate drives the two support rods to move, and the two support rods respectively drive the two sliders away from each other, and the two sliders respectively squeeze the secondary buffer springs, which offset the downward external force. When the main buffer spring rebounds upward, the damping effect of the first-level damping telescopic rod reduces the rebound rate of the main buffer spring, so that the placement plate rises slowly and the storage tank rises slowly, reducing the up and down shaking of the storage tank. When subjected to left and right horizontal external forces, the two stabilizing blocks are forced to move and simultaneously squeeze the roll buffer spring, which offsets the horizontal external force and reduces the rebound rate of the roll buffer spring through the damping effect of the second-level damping telescopic rod, thereby reducing the left and right shaking amplitude of the storage tank, thereby achieving the effect of protecting the storage tank during transportation.

[0015] 2. In the present invention, a controller controls multiple electric lifting rods, which drive corresponding buffer plates to move upward, and the buffer plates drive the storage tanks to move upward, thereby facilitating the taking and placing of the storage tanks.

[0024] A liquid nitrogen tank for storing fish sperm comprises a liquid nitrogen box 1, a box cover 2 is rotatably mounted on the upper side of the liquid nitrogen box 1, an injection hole is opened on one side of the liquid nitrogen box 1, a nitrogen injection tube 4 is installed in the injection hole, a plurality of air holes are opened on the inner wall of the liquid nitrogen box 1, a plurality of buffer assemblies are installed on the inner bottom wall of the liquid nitrogen box 1, the liquid nitrogen box 1 is provided with a storage tank 18 via the buffer assembly, the buffer assembly comprises a buffer plate 5, a primary damping telescopic rod 7 is installed on the inner bottom wall of the buffer plate 5, a placement plate 9 is installed on the top end of the primary damping telescopic rod 7, a main buffer spring 8 is sleeved and mounted on the surface of the primary damping telescopic rod 7, the placement plate 9 is adapted to the storage tank 18, and a secondary buffer assembly is installed on the upper side of the buffer plate 5.

[0025] Based on the above structure, the interior of the liquid nitrogen box 1 is hollow, and liquid nitrogen can be injected through the nitrogen injection pipe 4 to achieve the effect of lowering the temperature in the box to preserve fish sperm. The liquid nitrogen box 1 has four built-in placement slots, each of which is equipped with the same buffer assembly. The buffer assembly can effectively buffer the storage tank 18 placed in the placement slot. The storage tank 18 is made of glass. A pull-out handle is installed on the upper side of the storage tank 18 for easy removal. A moving handle is installed on the upper side of the box cover 2 for carrying the device.

[0026] Example 1

[0027] like Figure 2 、 3 As shown in Figure 4, the buffer assembly includes several mounting plates 10, and the several mounting plates 10 are all installed on the inner wall of the buffer plate 5. The opposite surfaces of the two mounting plates 10 are installed with the same slide bar 11, and the surface of the slide bar 11 is sleeved with two sliders 12. The upper sides of the two sliders 12 are rotatably installed with support rods 13, and the top ends of the two support rods 13 are rotatably connected to the lower side of the placement plate 9. Four mounting blocks are installed on the lower side of each mounting plate 10, and the same slide bar 11 is installed between the two opposite mounting plates 10.

[0028] like Figure 2 、 3As shown in Figure 4, two auxiliary buffer springs 14 are installed on the surface of the slide rod 11, and the two auxiliary buffer springs 14 are adapted to the beam slider 12. Auxiliary buffer springs 14 are installed correspondingly at the positions close to the two end areas of the slide rod 11. One end of the auxiliary buffer spring 14 is connected to one side of the mounting block, and the other end of the auxiliary buffer spring 14 is connected to one side of the slider 12. The placement plate 9 drives the two support rods 13 to move, and the two support rods 13 respectively drive the two sliders 12 away from each other. The two sliders 12 respectively squeeze the auxiliary buffer springs 14, and the auxiliary buffer springs 14 offset the downward external force. When the main buffer spring 8 rebounds upward, the damping effect of the first-level damping telescopic rod 7 reduces the rebound rate of the main buffer spring 8, so that the placement plate 9 rises slowly, thereby slowly rising the storage tank 18, and reducing the up and down shaking of the storage tank 18.

[0029] Example 2

[0030] like Figure 2 As shown, the buffer assembly also includes a plurality of secondary damping telescopic rods 15, which are all installed on the inner wall of the liquid nitrogen box 1.

The secondary damping telescopic rod 15 has a damping effect, which can reduce the rebound rate of the roll buffer spring 16. When subjected to left and right horizontal external forces, the two stabilizing blocks 17 are forced to move and squeeze the roll buffer spring 16 at the same time. The roll buffer spring 16 offsets the horizontal external force and reduces the rebound rate of the roll buffer spring 16 through the damping effect of the secondary damping telescopic rod 15, thereby reducing the left and right shaking amplitude of the storage tank 18.

[0032] Example 3

[0033] like Figure 1 and 3 As shown, a plurality of electric lifting rods 6 are installed on the inner bottom wall of the liquid nitrogen box 1, and a controller 19 is installed on one side of the liquid nitrogen box 1. The controller 19 is electrically connected to the plurality of electric lifting rods 6. The electric telescopic rod is a prior art and can be lifted and adjusted to control the buffer plate 5 to move up and down. An electric lifting adjustment rod is installed on the inner bottom wall of each mounting groove, and can be individually controlled by the controller 19. The controller 19 controls multiple electric lifting rods 6. The electric lifting rod 6 drives the corresponding buffer plate 5 to move upward, and the buffer plate 5 drives the storage tank 18 to move upward, thereby achieving the effect of facilitating the taking and placing of the storage tank 18.

[0034] like Figure 1 As shown, a lock buckle 3 is installed on one side of the liquid nitrogen box 1, and the box cover 2 can be locked on the liquid nitrogen box 1 through the lock buckle 3 to prevent the box cover 2 from being opened during transportation.
