[0002] Mice, also known as white mice, belong to the phylum Chordata, class Mammalia, order Rodentia, and family Muridae. They are small, easy to raise and manage, easy to control, reproduce quickly, and can be weaned at 3 weeks old. Numerous inbred strains, mutant strains, and closed colonies with different characteristics have been developed, and several internationally recognized standard strains have been formed, widely used in various nutritional experimental studies. During the breeding process, white mice need to be raised in enclosures. For example, when using the Zhike M1 mouse cage, the top shelf needs to be removed, and the mice inside the enclosure transferred to a new enclosure. At this time, the top of the enclosure is open, allowing the mice to easily climb out. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 5 This utility model provides a technical solution: a zoological experimental animal feeding device, including a feeding box 1, a top groove 2 on the top of the feeding box 1, a top frame 3 placed inside the top groove 2, a partition column 4 fixedly connected inside the top frame 3, a fixed plate 5 fixedly connected to the top of the top frame 3, one end of the fixed plate 5 being located above the feeding box 1, two side plates 6 fixedly connected to the top of the fixed plate 5, a rotating column 8 rotatably connected between the two side plates 6 via a bearing, a connecting block 7 fixedly connected to the outside of the rotating column 8, a baffle 23 fixedly connected to one end of the connecting block 7, the baffle 23 being located inside the top frame 3, a drive box 13 fixedly connected to the back of one side plate 6, one end of the rotating column 8 extending into the drive box 13, a spring 10 installed on one side of the inner cavity of the drive box 13, one end of the spring 10 being fixedly connected to the inner wall of the drive box 13, and the other end of the spring 10 being fixedly connected to the outside of the rotating column 8.

[0016] Inside the top frame 3 and behind the partition column 4, several support columns 18 are fixedly connected. A water bottle 19 is placed on top of the support columns 18. The water bottle 19 uses an existing mouse feeder.

[0017] Both sides of the top frame 3 are fixedly connected with threaded blocks 14. The top of the feeding box 1 and the outer side of the threaded blocks 14 are provided with mounting grooves 16. The inside of the threaded blocks 14 is threaded with second quick-turn screws 15. The inside of the feeding box 1 and the lower side of the mounting grooves 16 are provided with threaded holes 17. The bottom end of the second quick-turn screws 15 extends into the threaded holes 17 and is threaded into the threaded holes 17. The position of the top frame 3 is limited and fixed by the second quick-turn screws 15, the mounting grooves 16 and the threaded holes 17.

[0018] A handle 20 is fixedly connected to the top of the baffle 23. A counterweight 21 is fixedly connected to the top of the baffle 23 and in front of the handle 20. Limiting blocks are fixedly connected to both sides of the top of the baffle 23 and above the top frame 3, so that when the baffle 23 is inside the top frame 3, the limiting blocks contact the top of the top frame 3 to limit the position of the baffle 23.

[0019] The other end of the rotating column 8 extends to the outside of the side plate 6 and is fixedly connected to a knob 9. The knob 9 is internally threaded with a first quick-tight screw 11. Two insertion holes 12 are opened on the surface of the side plate 6. One end of the first quick-tight screw 11 extends into the corresponding insertion hole 12 and cooperates with the inside of the insertion hole 12. By cooperating with the first quick-tight screw 11 through the two insertion holes 12, the position of the baffle 23 can be limited and fixed.

[0020] The top of the baffle 23 has several through holes 22, which allow the inside of the feeding box 1 to be ventilated.

[0021] In summary, when using this experimental animal feeding device for zoology, the top frame 3 is placed on top of the top groove 2, so that the threaded block 14 is located inside the mounting groove 16, and then the bottom end of the second quick-release screw 15 is screwed into the threaded hole 17. When it is necessary to change the bedding inside the feeding box 1, hold the counterweight 21 with one hand, and drive the baffle 23 to rotate through the counterweight 21, so that the top of the top frame 3 opens. Grab the experimental mouse from inside the feeding box 1 with the other hand, and then release the handle 20. At this time, the spring 10 drives the rotating column 8 under the action of its own elastic potential energy, which drives the connecting block 7 and the baffle 23 to rotate into the top frame 3. Then, holding the counterweight 21 with one hand, the counterweight 21 drives the baffle 23 to rotate, causing the top of the top frame 3 to open. With the other hand, the experimental mouse is placed into the feeding box 1 with new bedding. Then, the handle 20 is released. At this time, the spring 10 drives the rotating column 8 under its own elastic potential energy, causing the connecting block 7 and the baffle 23 to rotate into the top frame 3. The above transfer process is for adult mice. When handling young mice, one hand can hold the counterweight 21 and use the counterweight 21 to rotate the baffle 23, so that the top of the top frame 3 is opened. Then, one end of the first quick-release screw 11 is screwed into the lower insertion hole 12 to limit the position of the knob 9, the rotating column 8, the connecting block 7, and the baffle 23. Therefore, it is not necessary to rotate the baffle 23 every time a young mouse is picked up. After the experimental mice are removed, one end of the second quick-release screw 15 is unscrewed from the threaded hole 17, then the top frame 3 is removed from the top groove 2, then the old bedding is removed from the breeding box 1, and after the device is disinfected, the top frame 3 is placed into the top groove 2, and then the bottom end of the second quick-release screw 15 is screwed into the threaded hole 17 to fix the top frame 3 in the top groove 2, so that the top frame 3 is installed on the top of the breeding box 1.
