[0031] Please refer to Figures 1-5 , the present utility model provides a technical solution: a double-sided ventilated cage for raising experimental animals, including a cage body 1, a collection box 2 fixedly connected to the lower surface of the cage body 1, a sealing door 3 installed on the side of the cage body 1, a control device 4 arranged inside the cage body 1, and a fixing device 5 arranged on the surface of the cage body 1.

[0033] Such as Figures 1-4As shown in the figure, the control device 4 includes a number of pressing plates 402, and a number of pressing plates 402 are all installed inside the cage body 1. One end of a number of pressing plates 402 is fixedly connected to a first control rod 401, and the first control rod 401 is slidably connected to the surface of the cage body 1. The other end of a number of pressing plates 402 is fixedly connected to a second control rod 403, and the second control rod 403 is slidably connected to the surface of the cage body 1. By providing the first control rod 401 and the second control rod 403, the position of the pressing plate 402 can be conveniently moved. By providing the pressing plate 402, the experimental animals can be controlled, thereby improving the safety during the process of taking the experimental animals.

One side of the first fixing plate 404 close to the second fixing plate 405 is fixedly connected to a stabilizing rod 406, and the other end of the stabilizing rod 406 is fixedly connected to the second fixing plate 405. By providing the first fixing plate 404 and the second fixing plate 405, the stabilizing rod 406 can be connected to the cage body 1. By providing the stabilizing rod 406, the stability of the first control rod 401 during movement can be improved.

[0034] A grip 407 is fixedly connected to the side of the first control rod 401 away from the second control rod 403. Two chutes are provided on one side of the cage body 1 close to the second control rod 403, and sliders 408 are slidably connected to the surfaces of the chutes on the two cage bodies 1. The sliders 408 are fixedly connected to the second control rod 403. By providing the grip 407, the first control rod 401 can be conveniently moved. By providing the sliders 408, while connecting the second control rod 403 to the cage body 1, it is ensured that the second control rod 403 can move. A sliding rod 409 is slidably connected to the inner wall of the slider 408, and the sliding rod 409 is fixedly connected to the surface of the chute on the cage body 1. A first spring 410 is sleeved on the surface of the sliding rod 409, and both ends of the first spring 410 are fixedly connected to the slider 408 and the cage body 1 respectively. By providing the sliding rod 409, the position of the first spring 410 can be restricted. By providing the first spring 410, the position of the slider 408 can be restricted, and at the same time, it is ensured that after the slider 408 moves, it can return to its original position.

[0035] As Figure 1 and Figure 2 and Figure 5As shown, the fixing device 5 includes a limit plate 53, which is slidably connected to the surface of the cage body 1, and the limit plate 53 is tightly fitted with the cage body 1. The upper surface of the limit plate 53 is fixedly connected to the mounting plate 54, and the inner wall of the mounting plate 54 is slidably connected to the limit rod 55, and the end of the limit rod 55 away from the pressing plate 402 is fixedly connected to the pull plate 56. By setting the limit plate 53, the mounting plate 54 and the limit rod 55 can be installed, and by setting the pull plate 56, the limit rod 55 can be easily moved, and by setting the limit rod 55, the position of the pressing plate 402 can be fixed.

[0036] The surface of the limiting rod 55 is sleeved with a second spring 57, and the two ends of the second spring 57 are fixedly connected to the pull plate 56 and the mounting plate 54 respectively. By setting the pull plate 56, the second spring 57 can be easily installed, and by setting the second spring 57, the position of the limiting rod 55 can be limited. The side of the collection box 2 close to the limiting plate 53 is fixedly connected with an arc plate 51, and the inner wall of the arc plate 51 is threadedly inserted with a threaded rod 52, and the threaded rod 52 is rotatably connected to the limiting plate 53. By setting the arc plate 51, the threaded rod 52 can be connected to the collection box 2, and the threaded rod 52 rotatably connected to the limiting plate 53 can move the limiting plate 53 without driving the limiting plate 53 to rotate. By rotating the threaded rod 52, the position of the limiting plate 53 can be adjusted.

[0037] Working principle: When it is necessary to grab the experimental animal in the cage body 1, grab the handle 407 and control the first control rod 401 to slide on the surface of the stabilizing rod 406. At this time, the first control rod 401 drives the pressure plate 402 and the second control rod 403 to move close to the experimental animal. At the same time, the second control rod 403 drives the slider 408 to slide on the surface of the slide rod 409, so that the pressure plate 402 controls the experimental animal. Then, open the sealing door 3, grab the experimental animal, release the handle 407, and under the action of the elastic force of the first spring 410, the second control rod 403 drives the slider 408 to slide on the surface of the slide rod 409. A control rod 401 moves away from the collection box 2 to complete the capture of the experimental animal. By setting the first fixing plate 404 and the second fixing plate 405, the stabilizing rod 406 can be installed. By setting the stabilizing rod 406, the stability of the first control rod 401 during movement can be improved. By setting the control device 4, when it is necessary to take out the experimental animal in the double-sided ventilation cage, the experimental animal can be controlled first and then taken out, thereby avoiding as much as possible the occurrence of situations such as staff being scratched when capturing the experimental animal.

[0038] When it is necessary to control laboratory animals, the threaded rod 52 is rotated according to the body size of the laboratory animals. At this time, the threaded rod 52 rotates on the inner wall of the arc-shaped plate 51 and the surface of the limiting plate 53. Since the limiting plate 53 is in contact with the surface of the cage body 1, the rotation of the threaded rod 52 will not drive the limiting plate 53 to rotate. After the position of the mounting plate 54 is adjusted by rotating the threaded rod 52, the pull plate 56 is pulled to drive the limiting rod 55 to slide on the inner wall of the mounting plate 54. Then, the pressing plate 402 is moved to control the laboratory animals. When the pull plate 56 is released, under the action of the elastic force of the second spring 57, the limiting rod 55 moves closer to the second control rod 403, thereby fixing the position of the pressing plate 402. By setting the fixing device 5, the position of the pressing plate 402 can be restricted after the laboratory animals are controlled, so that the staff can conveniently control and capture the laboratory animals, thereby reducing the complexity of capturing the laboratory animals and facilitating the capture work of the staff.
