[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0028] A pig semen freezing and storage device, such as Figures 1 to 5 As shown, it includes a liquid nitrogen tank 1 and a storage component fixed to the bottom of a sealing cover plate 2, a one-way tooth plate 5 is fixed to the bottom of the sealing cover plate 2 by screws, and a accommodating frame 16 is welded to the side wall of the liquid nitrogen tank 1, a through hole opened at one end of the accommodating frame 16 is slidably connected with a T-shaped rod 17, and a clamping tooth 19 used in conjunction with the one-way tooth plate 5 is fixed to one end of the T-shaped rod 17 by screws, a spring 18 is sleeved on the outer wall of the T-shaped rod 17, and both ends of the spring 18 are fixed to the outer wall of one side of the accommodating frame 16 and the inner wall of one side of the T-shaped rod 17 by clamping;

[0029] By providing a preservation component, pig semen can be preserved. By injecting liquid nitrogen into the liquid nitrogen tank 1, the preservation component is placed inside the liquid nitrogen tank 1, and the pig semen is frozen and preserved in a liquid nitrogen low-temperature environment. When the pig semen needs to be taken out or stored, the one-way tooth plate 5 is slid up along the latch teeth 19. Since the one-way tooth plate 5 can only slide in one direction along the surface of the latch teeth 19, it will be limited by the latch teeth 19. Therefore, when the sealing cover plate 2 is raised to a certain height along the liquid nitrogen tank 1, the latch teeth 19 are used to support the one-way tooth plate 5, thereby preventing the sealing cover plate 2 from falling under the action of its own gravity during the process of taking and placing the pig semen;

[0030] When the pig semen is taken out and placed, the T-bar 17 is pulled along the receiving frame 16 to disengage the latching teeth 19 from the one-way tooth plate 5. At this time, the one-way tooth plate 5 loses the limit of the latching teeth 19, so that the sealing cover plate 2 moves down again to seal the liquid nitrogen tank 1. A rubber plug is fixed to the bottom of the sealing cover plate 2, and the rubber plug can improve the sealing effect of the sealing cover plate 2 on the liquid nitrogen tank 1.

[0031] Further, the storage assembly includes a mounting rod 13 and a placement box 9, the mounting rod 13 is fixed to the bottom of the sealing cover plate 2 by screws, and the placement box 9 is welded to the bottom of the mounting rod 13, the storage assembly also includes a test tube 10 and a mounting groove 15, the mounting groove 15 is annularly opened at the bottom of the placement box 9, and the test tube 10 is plugged into the mounting groove 15;

[0032] The installation groove 15 allows the test tube 10 to be placed by insertion, and the test tube 10 can store pig semen.

[0033] The top and middle of the mounting rod 13 are respectively provided with a threaded portion 12 and a threaded portion 2 14, and a protective plate 24 is sleeved on the outer wall of the mounting rod 13, and a nut adapted to the threaded portion 12 and the threaded portion 2 14 is embedded on the surface of the protective plate 24, and a handle 11 is integrally formed on the top of the protective plate 24;

[0034] In order to prevent the test tube 10 from escaping from the mounting groove 15, a protective plate 24 is provided to cover the top of the placement box 9. The protective plate 24 serves as a limit for the top of the test tube 10 to ensure the stability of the test tube 10 in the mounting groove 15. The threaded portion 14 is provided so that the relative stability between the protective plate 24 and the placement box 9 is ensured when the protective plate 24 rotates along the threaded portion 14. The threaded portion 12 is provided so that when the test tube 10 needs to be taken out of the mounting groove 15, the height of the protective plate 24 is limited by first sliding up along the mounting rod 13 and then screwing into the threaded portion 12. This ensures that the protective plate 24 is stable on the top of the mounting rod 13 when the test tube 10 is taken out and placed.

[0035] Furthermore, a mounting block 3 is welded on the top of the sealing cover plate 2, and a handle 4 is rotatably connected between the two mounting blocks 3;

[0036] The handle 4 is provided to facilitate lifting of the entire device.

[0037] Working principle: When pig semen needs to be preserved, first slide the one-way tooth plate 5 up along the latch teeth 19. When the sealing cover plate 2 moves to a certain height, place the test tube 10 in the mounting groove 15, move the protective plate 24 to the threaded portion 14, rotate the protective plate 24 along the threaded portion 14, and use the protective plate 24 to limit the top of the placement box 9. Then, pull the T-bar 17 outward along the receiving frame 16. When the latch teeth 19 and the one-way tooth plate 5 are disengaged from each other, the one-way tooth plate 5 slides down along the receiving frame 16, and the sealing cover plate 2 is used to seal the liquid nitrogen tank 1.

[0038] Example 2

[0039] A pig semen freezing storage device, in order to ensure the relative stability between the sealing cover plate 2 and the liquid nitrogen tank 1 after being sealed, such as Figures 1 to 5 As shown, this embodiment makes the following supplements on the basis of embodiment 1: the bottom of the sealing cover plate 2 is fixed with a limit plate 7 by screws, and the side wall of the limit plate 7 is provided with a slot 8, the side wall of the liquid nitrogen tank 1 is fixed with a limit seat 6 by screws, and one end of the limit seat 6 is provided with a plug hole 20, a U-shaped frame 21 is welded to the outer wall of one side of the limit seat 6, and a threaded column 22 is threadedly connected to the surface of the U-shaped frame 21, and a plug 23 adapted to the inner diameter of the plug hole 20 and the slot 8 is welded to one end of the threaded column 22;

[0040] When the liquid nitrogen tank 1 and the sealing cover plate 2 are closed, the slot 8 and the jack 20 are in a facing position, and the threaded column 22 is rotated so that the plug 23 is inserted into the jack 20 and the slot 8 in turn, so as to realize the

[0041] Indirect fixation between the liquid nitrogen tank 1 and the sealing cover plate 2.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
