Abstract
Description
Technical Field
[0001] This utility model relates to the field of cage technology, and in particular to an independent air-supplied rabbit isolation cage for laboratories. Background Technology
[0002] Laboratory-grade, individually-ventilated rabbit isolation cages are crucial equipment in modern biological research, especially in experiments involving rabbits, where their importance is increasingly evident. These cages are designed to create an independent, stable, and suitable living environment for laboratory rabbits. An independent ventilation system ensures a consistent supply of fresh air, reducing the risk of disease transmission between rabbits and also helping to maintain a clean and hygienic experimental environment.
[0003] Existing laboratory rabbit isolation cages typically consist of a basic cage frame, usually made of sturdy and corrosion-resistant metal or high-strength plastic to ensure stability and durability. The cage interior is equipped with simple feeding and watering devices to meet the rabbits' basic survival needs. Ventilation relies on relatively traditional vent designs, allowing limited air circulation within the cage through natural ventilation or simple fan assistance. In daily operations, researchers primarily use standard operating ports on the cage to place and remove rabbits and perform basic observations.
[0004] However, existing laboratory rabbit isolation cages have certain problems in practical use. Due to their relatively fixed internal structure design, they cannot be reasonably adjusted according to the different body sizes of experimental rabbits. In actual scientific research experiments, rabbits vary greatly in size due to factors such as breed, age, and breeding conditions. The existing fixed spatial layout often causes smaller rabbits to feel uneasy in overly large spaces, affecting their normal physiological and behavioral states; for larger rabbits, cramped spaces restrict their movement and may even adversely affect their limb development and health. This limitation in spatial layout seriously restricts the smooth conduct of experiments and cannot meet the increasingly diverse and sophisticated experimental needs. Therefore, a laboratory rabbit isolation cage with independent ventilation is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a laboratory-independent air-supplied rabbit isolation cage, which aims to improve the problem that the internal space layout of the equipment is relatively fixed and it is difficult to make targeted adjustments according to the different body sizes of rabbits and specific experimental needs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A laboratory-independent air-supplied rabbit isolation cage includes an isolation cabinet. Both sides of the isolation cabinet are rotatably connected to doors. A transparent observation panel is fixedly connected inside each door. An adjustment component is installed inside the isolation cabinet, and a purification component is installed on one side of the isolation cabinet.
[0008] The adjustment assembly includes multiple isolation plates located inside the isolation cabinet. A support plate is fixedly connected to the inner wall of the isolation cabinet. Multiple limiting posts are fixedly connected inside the support plate. A spring is provided on the outer wall of each limiting post. A protective pad is fixedly connected to one end of each spring. A connecting plate is fixedly connected to the other end of each spring. The spring is fixedly connected to the outer wall of the limiting post. The connecting plate is slidably connected to the outer wall of the limiting post. A baffle is fixedly connected to one side of each connecting plate. A slider is fixedly connected to one side of each isolation plate. The slider is slidably connected inside the support plate.
[0009] As a further description of the above technical solution:
[0010] The purification component includes multiple filters, which are located on one side of the isolation cabinet, and multiple fixing blocks are fixedly connected to one side of the isolation cabinet.
[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:
[0014] Each fixing block is fixedly connected to a fixing tube on one side, and a connecting ring is slidably connected inside each fixing tube;
[0015] As a further description of the above technical solution:
[0016] Each of the connecting rings has multiple slots inside, and the inner wall of each connecting ring is fixedly connected to the outer wall of the filter screen.
[0017] As a further description of the above technical solution:
[0018] The filter screen is located on one side of the activated carbon protective plate, and the filter screen is used to filter out dust and larger particles in the air.
[0019] As a further description of the above technical solution:
[0020] Each of the fixed tubes is provided with a second spring on its outer wall. One end of each second spring is fixedly connected to a fixed ring, and the other end of each second spring is fixedly connected to a retaining ring.
[0021] As a further description of the above technical solution:
[0022] The inner wall of each fixed ring is fixedly connected to the outer wall of the fixed tube, and multiple locking balls are slidably connected inside each fixed tube, with the locking balls engaging with the locking grooves.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the slider at the bottom of the isolation plate slides in different grooves inside the support plate, thereby making targeted adjustments to the internal spatial layout of the isolation cabinet. Furthermore, the baffle is used to fix the position of the isolation plate, which solves the problem that the internal spatial layout of the equipment is relatively fixed and it is difficult to make targeted adjustments according to the different body sizes of rabbits and specific experimental needs, thus enhancing the applicability of the equipment.
[0025] 2. In this utility model, the air entering the equipment is purified by a filter screen and an activated carbon protective plate.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a laboratory independent air-supplied rabbit isolation cage, including an isolation cabinet 1, with door panels 2 rotatably connected to both sides inside the isolation cabinet 1, a transparent observation panel 3 fixedly connected inside each door panel 2, an adjustment component inside the isolation cabinet 1, and a purification component on one side of the isolation cabinet 1.
[0034] The adjustment assembly includes multiple partition plates 4, located inside the isolation cabinet 1. The main function of the partition plates 4 is to flexibly divide the space within the isolation cabinet 1 by changing their positions to meet different experimental needs and accommodate rabbits of varying sizes. A support plate 6 is fixedly connected to the inner wall of the isolation cabinet 1. The support plate 6 plays a crucial role in supporting and fixing other components, providing a stable structural foundation for the entire adjustment assembly and ensuring that all components remain stable during adjustment. Multiple limiting posts 9 are fixedly connected inside the support plate 6. Each limiting post 9 has a spring 10 on its outer wall. Each spring 10 has a protective pad 8 fixedly connected to one end, and a connecting plate 11 fixedly connected to the other end. The spring 10 is fixedly connected to the outer wall of the limiting post 9, and the connecting plate 11 is slidably connected to the outer wall of the limiting post 9. Each connecting plate 11 has a baffle 7 fixedly connected to one side, and each isolation plate 4 has a slider 5 fixedly connected to one side. The slider 5 is slidably connected to the inside of the support plate 6. The cooperation structure between the slider 5 and the support plate 6 allows the isolation plate 4 to slide easily on the support plate 6, making it convenient for operators to quickly and easily adjust the position of the isolation plate 4 according to actual needs.
[0035] Specifically, in actual experimental scenarios, different experimental projects have diverse requirements for the rabbit's activity space. Therefore, it is necessary to flexibly and precisely adjust the internal space of the isolation cabinet 1 according to the rabbit's size and specific experimental needs. The operator first manually pulls the baffle 7, which can smoothly move out from one side of the closely fitted slider 5. During this process, the connecting plate 11 connected to the baffle 7 will also slide stably on the outer wall of the limiting post 9. At the same time, the spring 10 is compressed by the pushing action of the connecting plate 11, thereby storing a certain amount of elastic potential energy. Then, the slider 5 at the bottom of the isolation plate 4 is supported. The plate 6 slides along a pre-designed track to adjust the position of the isolation plate 4. After the isolation plate 4 moves into the specific support plate 6 that meets the experimental requirements, the operator releases the pushing force on the baffle 7. At this time, the previously compressed spring 10 quickly pushes the baffle 7 to move in the opposite direction by its own rebound force until the baffle 7 moves precisely to one side of the slider 5. By making full use of the close fit between the baffle 7 and the slider 5, the position of the slider 5 is effectively limited and fixed, thereby achieving stable fixation of the adjusted position of the isolation plate 4. This enhances the applicability of the equipment and enables it to better meet the complex needs of various rabbit experiments.
[0036] Reference Figures 3-4The purification component includes multiple filters 17, which are located on one side of the isolation cabinet 1. The filters 17 perform preliminary purification of the air entering the isolation cabinet 1. With their fine mesh structure, they effectively filter out dust and larger particulate impurities from the air, preventing these pollutants from entering the isolation cabinet 1. Multiple fixing blocks 12 are fixedly connected to one side of the isolation cabinet 1. Each fixing block 12 has multiple activated carbon protective plates 18 fixedly connected inside. The activated carbon protective plates 18 are used to absorb and filter fine impurities in the air. Their rich activated carbon pore structure can adsorb harmful gases, odor molecules, and tiny suspended particles in the air, further improving the air purity and providing higher-quality breathing air for the experimental rabbits, reducing the interference of adverse external air factors on experimental results. The activated carbon protective plates 18 are used to absorb and filter fine impurities in the air. Each fixing block 12 has multiple activated carbon protective plates 18 fixedly connected to one side of the isolation cabinet 1. Each fixed tube 13 is connected to a fixed tube, and each fixed tube 13 has a connecting ring 16 slidably connected inside. Each connecting ring 16 has multiple slots 19 inside. The inner wall of each connecting ring 16 is fixedly connected to the outer wall of the filter screen 17. The filter screen 17 is located on one side of the activated carbon protective plate 18. The filter screen 17 is used to filter dust and larger particles in the air. Each fixed tube 13 has a spring 25 on its outer wall. One end of each spring 25 is fixedly connected to a fixed ring 21, and the other end of each spring 25 is fixedly connected to a retaining ring 14. The inner wall of each fixed ring 21 is fixedly connected to the outer wall of the fixed tube 13. Each fixed tube 13 has multiple retaining balls 20 slidably connected inside. The retaining balls 20 engage with the slots 19. Through the tight cooperation between the retaining balls 20 and the slots 19, the connecting rings 16 are precisely limited and fixed, ensuring that the filter screen 17 always remains in the correct position during equipment operation.
[0037] Specifically, during the operation of the laboratory equipment's ventilation system, outside air enters the internal space of the isolation cabinet 1 after passing through filter 17 and activated carbon protective plate 18. Filter 17, with its fine mesh structure, effectively intercepts and filters suspended dust particles in the air, preventing dust from entering the isolation cabinet 1 and thus avoiding contamination of the experimental rabbits and the experimental environment. Simultaneously, activated carbon protective plate 18, utilizing its abundant activated carbon pores, adsorbs and purifies harmful gases, odors, and other impurities in the air, ensuring that the air entering the isolation cabinet 1 remains dry in all aspects. The clean and fresh environment provides an excellent breathing environment for the experimental rabbits, effectively ensuring the smooth progress of the experiment and the health of the rabbits. After prolonged use, a large amount of dust will gradually accumulate on the surface of the filter screen 17, which will inevitably affect its filtration effect. Therefore, it is necessary to clean the dust on the surface of the filter screen 17 regularly. When cleaning the filter screen 17, the operator first manually pushes the retaining ring 14. During the movement of the retaining ring 14 under force, its original locking structure that cooperates with the retaining ball 20 will gradually separate. During this process, the spring 15 is compressed and deformed by the squeezing action of the retaining ring 14, storing a certain amount of... With elastic potential energy, the operator can then move the filter screen 17 and the connecting ring 16 connected to it along the inner wall of the fixed pipe 13. During this movement, the connecting ring 16 will exert a pushing force on the retaining ball 20, causing the retaining ball 20 to slide in a specific track inside the fixed pipe 13, thereby completely releasing the limiting effect on the filter screen 17 and the connecting ring 16, so that the filter screen 17 can be removed from the ventilation system for thorough dust cleaning. After the dust on the surface of the filter screen 17 is cleaned, the operator will realign the connecting ring 16 on the outer wall of the filter screen 17 with the inlet of the fixed pipe 13 and move it to the fixed pipe 13. Inside the fixed tube 13, the filter is restored to its initial installation position, achieving a preliminary reset operation. Subsequently, the operator releases the pressure on the retaining ring 14. At this time, the spring 15 generates a rebound force due to its stored elastic potential energy, pushing the retaining ring 14 to move quickly back to the side of the retaining ball 20 along its original movement path. During the movement, the retaining ring 14 pushes the retaining ball 20 back to its initial position, so that the retaining ball 20 is tightly locked and fixed to the inner wall of the groove 19 on the connecting ring 16, thereby achieving a quick and stable installation of the filter screen 17, enhancing the air purification effect and overall performance stability of the equipment.
[0038] Working Principle: During the adjustment of the internal space of the isolation cabinet 1 according to the rabbit's size and experimental requirements, the baffle 7 is pulled, causing it to move out from one side of the slider 5. This causes the connecting plate 11 to slide against the outer wall of the limiting post 9, compressing the spring 10. The slider 5 at the bottom of the isolation plate 4 then slides from inside the support plate 6. Next, another baffle 7 is pushed, moving the isolation plate 4 into the specific support plate 6. The pushing force on the baffle 7 is released, and the rebound force of the spring 10 pushes the baffle 7 to one side of the slider 5. The baffle 7 limits and fixes the position of the slider 5, thus fixing the adjusted position of the isolation plate 4 and enhancing the applicability of the equipment. During ventilation, the airflow passes through the filter screen 17 and the activated carbon protective plate 18 into the interior of the isolation cabinet 1. The filter screen 17 filters dust from the air, while the activated carbon protective plate... 18. Air purification ensures that the air entering the isolation cabinet 1 is clean and fresh. After prolonged use, the dust on the surface of the filter 17 needs to be cleaned. At this time, push the retaining ring 14. During the movement, the retaining ring 14 will separate from the retaining ball 20, and the spring 2 15 will be compressed. Then, the filter 17 and the connecting ring 16 will be moved out from the inner wall of the fixing tube 13. During this process, the retaining ball 20 will slide inside the fixing tube 13. Then, clean the dust on the surface of the filter 17. Next, move the connecting ring 16 on the outer wall of the filter 17 into the fixing tube 13 to reset it. Then, release the pressure on the retaining ring 14. The rebound force of the spring 2 15 will push the retaining ring 14 back to the side of the retaining ball 20, and push the retaining ball 20 to lock and fix it in place against the inner wall of the slot 19. This achieves quick installation of the filter 17 and enhances the air purification effect of the equipment.
