[0026] like Figure 1 , Figure 2 As shown, this utility model provides a multifunctional experimental rabbit restraint device, comprising:

[0027] The fixed box 7 has an abdominal exposure hole 20 on its bottom wall. A flexible support plate 14 that is detachably connected to the fixed box 7 is installed directly below the abdominal exposure hole 20. A pair of retractable support frames are detachably installed on both sides of the bottom of the fixed box 7.

[0028] The multifunctional experimental rabbit fixation device provided by this technical solution includes a fixation box 7 for holding experimental pregnant rabbits. An abdominal exposure hole 20 is provided on the bottom wall of the box. When the experimental pregnant rabbit is inside the fixation box 7, its abdomen protrudes from the bottom wall of the box 7 directly above the abdominal exposure hole 20. A flexible support plate 14 is raised and lowered directly below the abdominal exposure hole 20 to support the abdomen of the experimental pregnant rabbit and prevent it from sagging. The flexible support plate 14 can be made of nylon cloth, cotton cloth, gauze, etc., making it soft, breathable, and improving comfort. The flexible support plate 14 is detachably connected to the fixation box 7 for easy replacement and maintenance. A pair of retractable support frames are detachably provided on both sides of the bottom of the fixation box 7 to support the box 7 to a certain height, facilitating the raising, lowering, and disassembly of the flexible support plate 14. A head exposure hole is provided on one side wall of the fixation box 7 for the head of the experimental pregnant rabbit to extend out of the box 7 for head restraint. The top wall of the fixation box 7 is provided with an openable cover for easy loading and unloading of the experimental pregnant rabbit.

[0029] The method of using the multifunctional experimental rabbit fixation device provided by this technical solution is as follows: connect the flexible support plate 14, the support frame and the fixation box 7, then put the experimental pregnant rabbit into the fixation box 7 and make the abdomen of the experimental pregnant rabbit correspond to the abdominal exposure hole 20. The abdomen of the experimental pregnant rabbit protrudes from the fixation box 7 through the abdominal exposure hole 20. Then adjust the height of the flexible support plate 14 to an appropriate position to support the abdomen of the pregnant rabbit.

[0030] The present invention has at least the following beneficial effects: an abdominal exposure hole 20 is provided on the bottom wall of the fixed box 7, and a flexible support plate 14 is provided below the abdominal exposure hole 20. When the experimental pregnant rabbit is put into the fixed box 7, the abdomen of the experimental pregnant rabbit can protrude from the abdominal exposure hole 20 through the bottom wall of the fixed box 7. This can effectively prevent the experimental pregnant rabbit lying in the fixed box 7 from feeling uncomfortable due to pressure on the abdomen caused by the bottom wall of the fixed box 7 being too flat, avoid stress response in the pregnant rabbit, reduce the risk of miscarriage in the pregnant rabbit and adverse effects on the experiment.

[0031] The flexible support plate 14 supports the abdomen of the experimental pregnant rabbit to prevent the abdomen and body of the experimental pregnant rabbit from sagging. The flexible support plate 14 can semi-wrap and support the pregnant rabbit's abdomen according to its deformation, thereby improving the support comfort.

[0032] The flexible support plate 14 with lifting function can support the abdomen of pregnant rabbits of different sizes, making it more widely applicable;

[0033] The flexible support plate 14 is detachably connected to the fixed box 7, which facilitates the replacement and maintenance of the flexible support plate 14;

[0034] The bottom of the fixed box 7 is detachably equipped with a pair of telescopic support frames on both sides. The support frames support the fixed box 7 to a certain height, which facilitates the lifting, lowering and disassembling of the flexible support plate 14. The height of the fixed box 7 can be adjusted by adjusting the telescopic degree of the support frames to meet the requirements of different operating heights.

[0035] In another technical solution, such as Figure 1 , Figure 2 , Figure 3As shown, in the multifunctional experimental rabbit fixation device, multiple vertically distributed threaded rods 15 are detachably mounted on the bottom wall of the fixation box 7 around the abdominal exposure hole 20. First connecting rings 10 and adjusting nuts 9 are movably sleeved on the threaded rods 15, and the first connecting rings 10 are detachably connected to the flexible support plate 14. The adjusting nut 9 is connected to the threaded rods 15 via a threaded structure. Rotating the adjusting nut 9 changes its position on the threaded rods 15. As the adjusting nut 9 descends, the first connecting rings 10 descend along the threaded rods 15 under their own weight to adjust the height. When the adjusting nut 9 rises, it drags the first connecting rings 10 upwards along the threaded rods 15 to adjust the height, thereby adjusting the height of the flexible support plate 14. Rotating the adjusting nut 9 until it disengages from the threaded rods 15 allows the first connecting rings 10 to be removed from the threaded rods, thus separating the flexible support plate 14 from the fixation box 7. After removing the threaded rods 15 and the support frame, the fixation box 7 can be placed on a horizontal surface for use.

[0036] In another technical solution, such as Figure 1 As shown, in the multifunctional experimental rabbit fixation device, a second connecting ring 11 is provided on the first connecting ring 10, and multiple restraint ropes are provided on the edge of the flexible support plate 14. The restraint ropes are tied to their corresponding second connecting rings 11. The restraint ropes are flexible in binding and unbinding, facilitating the assembly and disassembly of the flexible support plate 14.

[0037] In another technical solution, such as Figure 1 , Figure 2 , Figure 3 As shown, in the multifunctional experimental rabbit fixation device, the bottom wall of the fixation box 7 is provided with multiple insertion holes 21 corresponding to the insertion of each threaded rod 15. An arc-shaped limiting protrusion 22 is provided at the end of the threaded rod 15 located inside the fixation box 7. A fixing nut 8, a first connecting ring 10, and an adjusting nut 9 are fitted onto the threaded rod 15 located outside the fixation box 7. The arc-shaped limiting protrusion 22 and the fixing nut 8 clamp the bottom wall of the fixation box 7. The fixing nut 8 is connected to the threaded rod 15 through a threaded structure, used to lock the position of the threaded rod 15 and the fixation box 7, preventing them from moving relative to each other at will. When rotating the adjusting nut 9, one hand can hold the threaded rod 15 while the other hand rotates the adjusting nut 9, preventing the threaded rod 15 from rotating with the adjusting nut 9. The upper surface of the arc-shaped limiting protrusion 22 is excessively smooth, which can reduce discomfort when the experimental pregnant rabbits come into contact with it.

[0038] In another technical solution, such as Figure 2 As shown, in the multifunctional experimental rabbit fixation device, the bottom edge of the fixing box 7 at the abdominal exposure hole 20 is wrapped with a protective layer 19. The protective layer 19 can be made of rubber, plastic, or cloth to improve the comfort of the pregnant experimental rabbits when touched.

[0039] In another technical solution, such as Figure 1 , Figure 4 As shown, in the multifunctional experimental rabbit fixation device, the support frame includes:

[0040] A pair of support tubes 3 are inclined, and the support tubes 3 are provided with multiple pairs of first support holes 2 distributed along their length direction. The support tubes 3 are provided with legs 18.

[0041] A pair of lifting rods 4 are inserted into a pair of support tubes 3. Each lifting rod 4 has a second support hole, and a positioning rod 1 is inserted into the corresponding first support hole 2 and second support hole. A connecting rod 23 is located at the top of each pair of lifting rods 4, and the connecting rod 23 is detachably connected to the fixed box 7. When the height of the fixed box 7 needs to be adjusted, the positioning rod 1 is pulled out from the first support hole 2 and the second support hole, the depth of the lifting rod 4 inserted into the support tube 3 is adjusted until the connecting rod 23 is at the desired height, and then the positioning rod 1 is inserted into the corresponding first support hole 2 and the second support hole. Multiple pairs of first support holes 2 are provided on the support tube 3 along its length to meet the different support height requirements of the connecting rod 23 and the fixed box 7. The angle between the support leg 18 and the support tube 3 is acute, forming a triangular support structure with the supporting ground, making the support frame more stable.

[0042] In another technical solution, such as Figure 1 , Figure 4 As shown, in the multifunctional experimental rabbit fixing device, a hinged tube 5 is rotatably sleeved on the connecting rod 23, and a connecting plate 16 is provided on the hinged tube 5. The connecting plate 16 is detachably connected to the fixing box 7. The hinged tube 5 can rotate around the connecting rod 23, and the connecting plate 16 is connected to the fixing box 7, indirectly making the fixing box 7 hinged to the connecting rod 23. This allows the fixing box 7 to flexibly adjust its tilt angle to meet more experimental operation requirements.

[0043] In another technical solution, such as Figure 1 , Figure 2 , Figure 3 As shown, in the multifunctional experimental rabbit fixing device, a pair of horizontal slots 6 are provided on both sides of the bottom of the fixing box 7, and a connecting plate 16 is inserted into each slot 6. The support frame can be connected or disassembled with the fixing box 7 by inserting or removing the connecting plate 16 into or from the slot 6, which is convenient and quick.

[0044] In another technical solution, such as Figure 1As shown, in the multifunctional experimental rabbit fixing device, a limiting rod 17 is detachably installed on the connecting plate 16, and the slot 6 is located between the limiting rod 17 and the hinge tube 5. The limiting rod 17 can be a screw, inserted into a threaded hole on the connecting plate 16; the limiting rod 17 prevents the connecting plate 16 from being pulled out of the slot 6 at will, thus improving structural stability.

[0045] In another technical solution, such as Figure 1 , Figure 2 As shown, in the multifunctional experimental rabbit fixation device, the bottom of the fixation box 7 is provided with a pair of horizontally opening support grooves 12. A support plate 13 is inserted into the pair of support grooves 12. The abdominal exposure hole 20 is located between the pair of support grooves 12 and directly above the support plate 13. Inserting or removing the support plate 13 into or from the support groove 12 can block or open the abdominal exposure hole 20. When special support is not required for pregnant rabbits and the experimental rabbit is non-pregnant, the flexible support plate 14 can be removed from the fixation box 7, and the support plate 13 can be inserted into the support groove 12 to block the abdominal exposure hole 20, thus providing stable support for the non-pregnant experimental rabbit.
