[0002] White mice refer to white-furred rats or mice that are commonly used as experimental animals in teaching and research in disciplines such as physiology, medicine, and pharmacy. Mice have poorer self-regulation ability to adapt to the environment and disease resistance than other experimental animals. Currently, non-toxic plastic mouse boxes and stainless steel wire cages are commonly used for raising them. However, traditional mouse cages are one-piece units, requiring each mouse to be removed individually when handling mouse excrement and leftover food. If the operator's hands or tools are not properly disinfected, pathogens can be transferred from one cage to another, increasing the risk of cross-infection. Utility Model Content

[0003] To address the shortcomings of existing technologies, when handling mouse excrement and leftover food, mice need to be removed one by one. If the operator's hands or tools are not properly disinfected, pathogens can be transferred from one cage to another, increasing the risk of cross-infection. This invention proposes a protective device for raising mice.

[0015] 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 scope of protection of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a protective device for raising mice. (Refer to...) Figures 1-6 A protective device for raising mice includes a mouse cage 1, an isolation cage 7 fixedly connected to one side of the mouse cage 1, and cage doors 4 on the top of both the mouse cage 1 and the isolation cage 7. A baffle 8 is slidably connected between the inner walls of the mouse cage 1 and the isolation cage 7, and is positioned between the mouse cage 1 and the isolation cage 7, sliding along the inner wall to isolate the two areas. A magnetic block 10 is provided on one side of the baffle 8, which can be attracted to a metal sheet on the inner wall of the mouse cage 1 or the isolation cage 7 for positioning and fixation. A sliding plate 5 is fixedly connected to the top of the baffle 8 for easy... The operator pushes the baffle 8 through the top opening; a magnetic block 10 is fixedly connected to one side of the baffle 8. The user moves the baffle 8 by holding the sliding plate 5, fixing it between the mouse cage 1 and the isolation cage 7; at the same time, the magnetic block 10 is fixedly connected to the side of the baffle 8 near the inner wall of the mouse cage 1. When the baffle 8 slides to the isolation position, the magnetic block 10 automatically attracts and fixes the baffle 8, preventing the mouse from pushing the baffle 8 back during the driving process, ensuring the isolation effect; this combination of magnetic block and sliding plate 5 design can achieve rapid isolation without the need for a lock.

[0017] A pull rod 6 is horizontally slidably connected to the inner wall of the mouse cage 1. A push plate 11 is fixedly connected to one side of the pull rod 6. The pull rod 6 extends out from the side wall of the mouse cage 1. The user can pull or push it from the outside to drive the push plate 11 to move horizontally inside the mouse cage 1, thereby driving the mouse into the isolation cage 7 and achieving contactless transfer.

[0018] The bottom of the mouse cage 1 is equipped with a disassembly and assembly mechanism 9, which includes a bottom plate mesh 901. The bottom plate mesh 901 is made of stainless steel or food-grade plastic and has uniform mesh holes on its surface to facilitate the fall of excrement and support the movement of the mouse. The bottom plate mesh 901 is horizontally slidably connected to the bottom of the inner wall of the mouse cage 1, and a locking cylinder 906 is fixedly connected to one side of the bottom plate mesh 901. A support block 12 is fixedly connected to the bottom of the mouse cage 1. A sliding rod 904 is slidably connected through the inner wall of the support block 12 and can slide in the horizontal direction. A spring 903 is fixedly connected to one side of the sliding rod 904. An installation block 902 is fixedly connected to the bottom of the isolation cage 7. One side of the installation block 902 is fixedly connected to the other side of the spring 903 so that the locking block 905 automatically locks into the locking cylinder 906 when there is no external force. The surface of the sliding rod 904 is fixedly connected to the locking block 905 for inserting into the locking cylinder 906 to achieve locking.

[0019] Reference Figure 5 A locking rod 18 is slidably connected to one side of the rat cage 1. The surface of the locking rod 18 is slidably connected to the inner wall of the connecting rod 907. The locking rod 18 is set in a horizontal direction, with one end protruding from the side wall of the rat cage 1 for easy removal by the user. The other end of the locking rod 18 extends into the rat cage 1 and is slidably connected to the inner wall of the connecting rod 907. The connecting rod 907 is fixed to the end of the sliding rod 904. When the user removes the locking rod 18 and releases the connecting rod 907, the connecting bracket 13 can be pulled to slide inside the connecting rod 907 and move backward as a whole. This causes the sliding rod 904 to move backward against the elastic force of the spring 903, so that the locking block 905 disengages from the locking cylinder 906 on the bottom plate mesh 901. The bottom plate mesh 901 can then be removed. This device extends the internal locking mechanism to the outside of the cage. The operator can disassemble the bottom plate without opening the cage door 4 or contacting the environment inside the cage, effectively preventing the spread of pathogens.

[0020] Reference Figure 4 A support slide rod 14 is fixedly connected to one side of the rat cage 1. A connecting frame 13 is fixedly connected to the surface of the slide rod 904. The inner wall of the connecting frame 13 is slidably connected to the surface of the support slide rod 14. The connecting frame 13 is fixedly connected to the surface of the slide rod 904, and its inner wall is in close contact with the surface of the support slide rod 14 and can slide to fit. This ensures that the slide rod 904 always maintains a straight movement during the force-driven movement, preventing jamming due to skew or the jamming block 905 failing to accurately align with the jamming cylinder 906. At the same time, the cooperation between the connecting frame 13 and the support slide rod 14 can enhance the structural rigidity of the entire disassembly and assembly mechanism 9 and extend the service life of the device.

[0021] Reference Figure 4A positioning block 15 is fixedly connected to one side of the base plate mesh 901. The positioning block 15 has a groove structure. A positioning rod 16 is fixedly connected to the bottom of the mouse cage 1. The positioning rod 16 has a cylindrical structure and its surface is slidably connected to the inner wall of the positioning block 15. When installing the base plate mesh 901, the operator aligns the positioning block 15 with the positioning rod 16 and pushes it in along its axis. This ensures that the base plate mesh 901 is accurately embedded in the predetermined position at the bottom of the mouse cage 1, avoiding misalignment that would prevent the locking cylinder 906 and the locking block 905 from engaging. This improves the installation efficiency of the base plate mesh 901 and also ensures the stability of the base plate mesh 901 during use, preventing shaking from affecting the mouse's activity or causing the mechanism to fail. Reference Figure 3 The bottom of the mouse cage 1 is fixedly connected with two positioning frames 17. The positioning frames 17 are installed on the bottom of the mouse cage 1 and are located on the left and right sides of the bottom plate mesh 901. The positioning frames 17 are rectangular frames, and their inner cavity dimensions match the edge of the bottom plate mesh 901. When the bottom plate mesh 901 is inserted into the bottom of the mouse cage 1, its edge can be embedded in the two positioning frames 17 to form a limiting relationship, effectively preventing the bottom plate mesh 901 from shifting or lifting during the mouse's activity or cleaning. By cooperating with the positioning block 15 and the positioning rod 16, the stability and positioning effect of the bottom plate mesh 901 installation are improved. Reference Figure 2 A support tube 2 is fixedly connected to one side of the rat cage 1. A food box 3 is slidably connected inside the support tube 2. The support tube 2 is a hollow cylindrical structure, with one end connected to the inside of the rat cage 1 and the other end open to the outside. The food box 3 is slidably connected inside the support tube 2 and can be freely pulled out along the axis. The front end of the food box 3 has a feed inlet and the rear end has a handle. When feeding, the user only needs to pull out the food box 3 from the outside, add feed, and then push it back into place. There is no need to open the cage door 4 throughout the process, which reduces the stress response of the mice and prevents external contaminants from entering the cage.

[0022] Working principle: First, place a tray under the bottom mesh 901. The mice move freely in the cage 1. Food is supplied through the food box 3. Excrement falls into the tray through the bottom mesh 901. When cleaning is needed, push the push plate 11 by pulling the lever 6 to drive all the mice to the isolation cage 7. Then close the baffle 8 and use the magnetic block 10 to fix it, so as to achieve complete isolation between the cage 1 and the isolation cage 7. When removing and cleaning the base plate mesh 901, the clamping rod 18 needs to be removed, and then the connecting frame 13 is pulled outward to move the connecting rod 907 and the sliding rod 904 backward. After the clamping block 905 releases the clamping cylinder 906, hold the edge of the base plate mesh 901 and pull it out horizontally along the direction of the positioning rod 16 to complete the disassembly. Clean the bottom mesh 901 with high-pressure steam or disinfectant, dry it, and then reinsert it into the bottom of the rat cage 1. During the pushing process, the positioning block 15 slides in along the positioning rod 16, the locking cylinder 906 aligns with the position of the locking block 905, the connecting frame 13 is released, the spring 903 pushes the sliding rod 904 to reset, the locking block 905 automatically embeds into the locking cylinder 906, and then the locking rod 18 is locked between the connecting rod 907 and the mouse cage 1 to complete the locking.

[0023] Open the baffle 8, and the mouse can freely return to the cage 1 to complete the entire contactless cleaning process.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
