Description

Technical Field

[0001] This utility model belongs to the field of bioengineering technology, specifically a fixture for transporting laboratory animals. Background Technology

[0002] The technical background of laboratory animal transportation primarily involves ensuring the safety and health of animals during transport. Since laboratory animals are frequently used in biomedical research, their health directly impacts experimental results; therefore, transportation equipment and methods must guarantee safety, comfort, and compliance. Transportation devices should prevent animal escape or injury, provide suitable space and environment to reduce stress, and have effective temperature control and ventilation systems to maintain appropriate temperature and air quality.

[0003] Disadvantages of transporting laboratory animals include the potential stress animals may experience due to environmental changes during transport, leading to reluctance to leave. Confined or unsuitable spaces can exacerbate this, making it difficult for animals to adapt to the new environment upon arrival. Furthermore, the sterilization process for transport equipment is often cumbersome and time-consuming, requiring strict adherence to biosafety standards to prevent cross-infection. This sterilization procedure not only increases operating costs but may also affect transport efficiency, prolong animal dwell time, and further increase the risks during transport.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-5 As shown, this utility model provides a technical solution:

[0022] A cage for transporting laboratory animals includes an outer shell 1, a gate 2 on one side of the outer shell 1, and sliding grooves on both sides inside the outer shell 1. A first groove is provided on the top of the outer shell 1, and second grooves are provided on both sides of the first groove. A servo motor 3 is fixedly connected to the inner side of the first groove. A reciprocating threaded rod 4 is coaxially fixedly connected to the output end of the servo motor 3. A first fixing block 5 is threadedly connected to the reciprocating threaded rod 4. L-shaped brackets 6 are fixedly connected to both sides of the first fixing block 5. Two sprayers 7 are provided in each of the two second grooves. A connecting rod 8 is fixedly connected between the two sprayers 7. The top surface of the connecting rod 8 is fixedly connected to one end of the L-shaped bracket 6.

[0023] The outer casing 1 is equipped with a push-pull type electric shock deflector mechanism;

[0024] Specifically, the animal is introduced into the shell 1 by opening the gate 2, and then the servo motor 3 and sprayer 7 are turned on. The output end of the servo motor 3 drives the reciprocating threaded rod 4. The rotation of the reciprocating threaded rod 4 causes the first fixing block 5, L-shaped bracket 6, connecting rod 8 and sprayer 7 to slide back and forth, so that the disinfectant sprayed by the sprayer 7 can be more evenly distributed to every corner.

[0025] The push-pull electric shock deflection mechanism includes an L-shaped block 9 fixedly connected to the bottom surface of the inner shell 1. Long plates are fixedly connected to both sides of the L-shaped block 9, and a first shaft is fixedly connected to the inner side of each long plate. A third groove is provided inside the L-shaped block 9, and an electric telescopic rod 10 is fixedly connected inside the third groove. A moving block 11 is fixedly connected to the output end of the electric telescopic rod 10. Push-pull components are provided on both sides of the moving block 11. Each push-pull component includes a first bracket 12 fixedly connected to one side of the moving block 11, a second bracket 13 rotatably connected to the middle of the first bracket 12, a first shaft passing through and rotatably connected to the second bracket 13, a third bracket 14 rotatably connected to one end of the first bracket 12, and a fourth bracket rotatably connected to one end of the second bracket 13. 15. Support No. 2 13 is rotatably connected to support No. 5 16 on one side. Support No. 3 14 is rotatably connected to the upper part of support No. 5 16 at one end. Support No. 5 16 is rotatably connected to support No. 6 17 at one end. Support No. 4 15 is rotatably connected to the middle part of support No. 6 17 at one side. Support No. 6 17 has a cylinder 18 on one side. Support No. 18 has a stop block fixedly connected to one end. Circular slider 19 is sleeved on the cylinder 18. Circular slider 19 is slidably connected to the cylinder 18. Support No. 2 shaft is fixedly connected to both sides of circular slider 19. Support No. 2 shaft passes through support No. 4 15 and is rotatably connected. Support No. 2 fixing block 20 is fixedly connected to the other end of cylinder 18. Support No. 6 17 is rotatably connected to one side of fixing block 20.

[0026] Specifically, opening the electric telescopic rod 10 moves the moving block 11 and the first bracket 12 on the output end. The movement of the first bracket 12 drives the second bracket 13 and the third bracket 14 to move together. The second bracket 13 moves in a circle around the first axis, which in turn drives the fourth bracket 15 to also move in a circle. The third bracket 14 and the fifth bracket 16 provide parallel support to ensure the stability of the overall structure. With the support of the second bracket 13 and the third bracket 14, the fifth bracket 16 moves in coordination with the fourth bracket 15, ultimately driving the sixth bracket 17 and the fixed block 20 to move. At the same time, the movement of the fourth bracket 15 also affects the second axis on the circular slider 19, ensuring that it slides on the abutment in the cylinder 18, so that the abutment can be controlled to the stretching distance. The above driving method only requires a small electric telescopic rod and a few brackets to achieve the required stretching length. This design not only meets the requirements for stretching length, but also effectively reduces costs.

[0027] Multiple small telescopic rods 21 are provided on the side of the second fixing block 20 away from the cylinder 18. Each of the multiple small telescopic rods 21 is fitted with a spring 22. A baffle 23 is fixedly connected to one end of each of the multiple small telescopic rods 21. A fourth groove is provided on the side of the baffle 23 near the second fixing block 20. An instantaneous switch is provided inside the fourth groove. Slider 24 is fixedly connected to both sides of the baffle 23. The slider 24 matches the slide groove. A conductive plate 25 is fixedly connected to the side of the baffle 23 away from the second fixing block 20. The conductive plate 25 is electrically connected to the instantaneous switch.

[0028] Specifically, when the second fixing block 20 moves forward, it will press the small telescopic rod 21 and the spring 22 to contact the instantaneous switch, which will energize the conductive plate 25. At the same time, it will push the baffle 23 and the conductive plate 25 to move. The movement of the baffle 23 will drive the slider 24 to move in the groove, so that the baffle 23 can move in parallel and stably. The above design can better drive the animals out of the shell 1 and reduce the risks faced by workers when handling animals.

[0029] The working principle of this utility model is as follows:

[0030] First, the animal is introduced into the shell 1 by opening the gate 2. Then, the servo motor 3 and the sprayer 7 are turned on. The output end of the servo motor 3 drives the reciprocating threaded rod 4. The rotation of the reciprocating threaded rod 4 causes the first fixing block 5, the L-shaped bracket 6, the connecting rod 8, and the sprayer 7 to slide back and forth. This allows the disinfectant sprayed by the sprayer 7 to be distributed more evenly to every corner.

[0031] Secondly, opening the electric telescopic rod 10 moves the moving block 11 and the first bracket 12 on the output end. The movement of the first bracket 12 drives the second bracket 13 and the third bracket 14 to move together. The second bracket 13 moves in a circle around the first axis, and also drives the fourth bracket 15 to move in a circle. The third bracket 14 and the fifth bracket 16 provide parallel support to ensure the stability of the overall structure. With the support of the second bracket 13 and the third bracket 14, the fifth bracket 16 moves in coordination with the fourth bracket 15, and finally drives the sixth bracket 17 and the fixed block 20 to move. At the same time, the movement of the fourth bracket 15 also affects the second axis on the circular slider 19, ensuring that it slides on the abutment in the cylinder 18, so that the abutment can be controlled to the stretching distance. The above driving method only requires a small electric telescopic rod and a few brackets to achieve the required stretching length. This design not only meets the requirements for stretching length, but also effectively reduces costs.

[0032] Finally, when the second fixing block 20 moves forward, it will press the small telescopic rod 21 and the spring 22 to touch the instantaneous switch, which will energize the conductive plate 25. At the same time, it will push the baffle 23 and the conductive plate 25 to move. The movement of the baffle 23 will drive the slider 24 to move in the groove, so that the baffle 23 can move in parallel and stably. The above design can better drive the animals out of the shell 1 and reduce the risks faced by workers when handling animals.
