[0021] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] The utility model proposes an animal experiment device with a replaceable experiment plate, comprising an experiment plate 1, wherein the experiment plate 1 is provided with a receiving groove 2, and a limiting rod 3 is movably connected to the experiment plate 1. Multiple limiting rods 3 are located above the receiving groove 2 and are arranged side by side, and multiple fixing devices 4 are slidably connected to the limiting rod 3.

[0023] A card block 5 is provided at the edge of the experimental board 1, and the limiting rod 3 is detachably connected to the experimental board 1 through the card block 5. The side opening of the card block 5 forms a card slot 6, and the limiting rod 3 is engaged with the card slot 6. The card blocks 5 are symmetrically arranged about the experimental board 1, and two rows of card blocks 5 are symmetrically arranged on the edge of the experimental board 1.

[0024] The card block 5 protrudes from the upper surface of the experimental board 1. The card block 5 includes a card block 1 7 and a card block 2 8 farther from the center of the experimental board 1. The side opening of the card block 1 7 forms a card slot 6. The card slot 6 includes a horizontal bottom surface 9 closer to the opening and an arc-shaped bottom surface 10 farther from the opening. The distance between the horizontal bottom surface 9 and the top surface of the card slot 6 is smaller than the distance between the arc-shaped bottom surface 10 and the top surface of the card slot 6. The card block 2 8 is arranged parallel to the card block 1 7, and the card block 2 8 corresponds to the arc-shaped bottom surface 10 of the card slot 6.

[0025] The width of the second clamping block 8 is equal to the diameter of the arc-shaped bottom surface 10 of the clamping slot 6 .

[0026] The distance between the symmetrically arranged blocks 5 is equal to the length of the limiting rod 3 .

[0027] Before use, the limiting rod 3 is separated from the experimental board 1. Specifically, the distance between the arcuate bottom surface 10 and the top surface of the card slot 6 is greater than the diameter of the limiting rod 3 and greater than the distance between the horizontal bottom surface 9 and the top surface of the card slot 6. During use, the end of the limiting rod 3 is located at the opening of the block 5. The limiting rod 3 is pushed horizontally into the card slot 6 and located at the arcuate bottom surface 10. Since the diameter of the limiting rod 3 is greater than the distance between the horizontal bottom surface 9 and the top surface of the card slot 6, the card slot 6 limits the horizontal displacement of the limiting rod 3; the two ends of the limiting rod 3 face the card block 2 8, which limits the displacement of the limiting rod 3 along the length direction.

[0028] The fixing device 4 includes a clamp 11 and a sliding ring 12. The clamp 11 is connected to the sliding ring 12 via a bracket. The clamp 11 includes a clip 13 and a torsion spring. The two clips 13 are connected by a torsion spring. The torsion spring is mounted on the bracket, and the two ends of the torsion spring are respectively connected to the clips 13. Specifically, the clips 13 are shaped like the Chinese character "匚". The clips 13 are symmetrically arranged. The bottom ends of the clips 13 are rotatably connected via the torsion spring. The clamp 11 has a large clamping space and a wide clamping range. When the clamp 11 is in a closed state, the sliding ring 12 is fixed in an appropriate position, and the clips 13 are opened to both sides to clamp the object.

[0029] The inner side of the clip 13 is provided with an airbag cavity 14, which is connected to a gas extraction and degassing device. The gas extraction and degassing device is conventional and will not be described in detail here. Because the size of different parts of the experimental animal's body varies greatly, the experimental animal to be fixed is relatively small. If the clamp 11 does not fit, the experimental animal is first placed in the clamp 11. The gas extraction and degassing device is then used to inflate the airbag cavity 14, causing it to expand and clamp the experimental animal.

[0030] The sliding ring 12 is slidably mounted on the limiting rod 3. The sliding ring 12 includes a circular ring body 15. The diameter of the circular ring body 15 is larger than that of the limiting rod 3. A brake rod 16 is vertically inserted through the circular ring body 15 and is rotatably connected to the circular ring body 15. Specifically, the brake rod 16 and the circular ring body 15 are rotatably connected by a threaded connection. One end of the brake rod 16 located inside the circular ring body 15 is fixedly connected to a brake plate 17, which is perpendicular to the length of the brake rod 16. The inward side of the brake plate 17 has an arcuate surface. Rotating the brake rod 16 drives the brake plate 17 to move linearly, causing the brake plate 17 to abut the limiting rod 3, thereby positioning the sliding ring 12.

[0031] Before the limiting rod 3 is connected to the experimental board 1, the sliding ring 12 is first put on the limiting rod 3. According to the required fixed part of the experimental animal, the sliding ring 12 is put on the corresponding limiting rod 3, and the position and angle of the sliding ring 12 are adjusted, and then the angle of the clamp 11 is adjusted to make it at a suitable clamping angle.

[0032] Working principle: Before use, the limiting rod 3 is separated from the experimental board 1. During use, according to the fixed part of the experimental animal to be fixed, the sliding ring 12 is placed on the corresponding limiting rod 3, the position and angle of the sliding ring 12 are adjusted, the brake rod 16 is rotated to position the sliding ring 12, the clamp 11 is at a suitable clamping angle, and the clamp 13 is opened to both sides to clamp the object; if the experimental animal body to be fixed is small and the clamp 11 does not match, the experimental animal body is first placed in the clamp 11, and the air bag cavity 14 is inflated through the air pumping and exhausting device. The air bag cavity 14 expands and clamps the experimental animal body. When the experimental board 1 is dirty and needs to be replaced, or when another experiment is required after an experiment is completed, the limiting rod 3 is moved toward the opening direction of the slot 6. The limiting rod 3 can be removed from the slot 6 while keeping the animal in a fixed state. The experimental board 1 can be replaced or moved.

[0033] Although the above embodiments have been shown and described, it is understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Changes, modifications, substitutions and variations of the above embodiments made by ordinary technicians in this field are all within the scope of protection of the present invention.
