Description

Technical Field

[0001] The utility model belongs to the field of animal breeding, and in particular relates to an experimental animal breeding cage which is convenient for changing bedding. Background Art

[0002] The bottom of the experimental cages in animal laboratories is usually filled with bedding, which is usually wood chips. Animals urinate and defecate in the cages. Because the experimental environment in the experimental animal cages needs to be kept clean and dry at all times, it is generally required to replace the bedding regularly and clean the cages. Currently, when replacing bedding in the laboratory, the experimenter first grabs the experimental animal from one cage to another, and then replaces or cleans the bedding in the empty cage. If the experimental animals are frequently grabbed, the final experimental results may be affected due to human interference factors caused to the experimental animals. In addition, repeated grabbing of experimental animals also increases the probability of experimental personnel being bitten by animals, posing a safety hazard. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] like Figure 1-Figure 7 As shown, an experimental animal breeding cage convenient for changing bedding includes an outer cage frame 1 and a baffle plate 2. The outer cage frame 1 is hollow inside and has openings at both ends. The baffle plate 2 is slidably connected to one end of the outer cage frame 1 near the upper opening. A first supporting plate 3 is provided at the lower opening of the outer cage frame 1. Figure 6 As shown, a flow mesh 4 is provided on the first supporting plate 3, and a sliding structure is provided at the bottom of the first supporting plate 3.

[0036] Further, such as Figure 1 and Figure 7 As shown, the sliding structure includes a base 5 and a second supporting plate 6, sliding grooves 7 are provided on both sides of the outer cage frame 1, and sliding parts 8 extend upward on both sides of the base 5. The sliding parts 8 are inverted L-shaped and the horizontal ends are slidably connected in the sliding grooves 7;

[0037] The second supporting plate 6 is embedded in the upper surface of the base 5 , and clamping parts 9 are extended upward on both sides of the second supporting plate 6 . The upper surface of the clamping part 9 abuts against the lower surface of the horizontal end of the sliding part 8 .

[0038] Further, such as Figure 2 and Figure 3 As shown, a plurality of mounting holes 10 are provided on both sides of the outer cage frame 1, and a rotating rod 11 is rotatably connected to each of the plurality of mounting holes 10, and a lifting hook 12 is fixedly connected to the rod body of the rotating rod 11;

[0039] like Figure 7 As shown, both sides of the first supporting plate 3 are provided with slots 13 corresponding to the lifting hooks 12 one by one, and the free ends of the lifting hooks 12 are inserted into the slots 13;

[0040] like Figure 5 and Figure 6 As shown, the bottom of the first supporting plate 3 is provided with an expansion groove 14 connected to the flow mesh 4, and the bottom of the first supporting plate 3 is provided with a vent hole 15 connected to the expansion groove 14, and the vent hole 15 and the slot 13 are located on the same side.

[0041] Further, such as Figure 6 and Figure 7 As shown, a placement groove 16 is provided on the top of the second supporting plate 6, and the diameter of the placement groove 16 is the same as that of the expansion groove 14;

[0042] A bedding layer 17 is laid in the placement groove 16, and the bedding layer 17 is located directly below the expansion groove 14. During the breeding process, the animal's excrement flows into the bedding layer 17 through the circulation mesh 4 and the excrement is collected. The air permeable holes 15 can increase the air circulation between the first supporting plate 3 and the second supporting plate 6, so that the odor can be quickly discharged with the air. The expansion groove 14 and the placement groove 16 can increase the volume between the first supporting plate 3 and the second supporting plate 6, so that the animal's excrement can fully fall into it.

[0043] Further, such as Figure 3 As shown in FIG. 1 , when the sliding portion 8 is pulled out significantly, the animal in the outer cage frame 1 and the gravity of the outer cage frame 1 will deviate sideways, thereby causing the sliding portion 8 in the sliding groove 7 to be subjected to excessive squeezing force, resulting in damage to the sliding portion 8, such as Figure 2 As shown, a clamping piece 18 is symmetrically fixedly connected to the lower side of the outer cage frame 1, and a rotating shaft 19 is rotatably connected between the two clamping pieces 18. A roller 20 is fixedly connected to the rotating shaft 19. The outer cage frame 1 can be supported by the provided clamping piece 18 and the roller 20 to ensure stability when it is pulled out. At the same time, the roller 20 and the lower surface of the base 5 are on the same water surface line to prevent the outer cage frame 1 from lateral deviation when it is pulled out, thereby providing protection for the sliding groove 7 and the sliding portion 8; a handle 21 is also fixedly connected to the outer cage frame 1, and the handle 21 is on the same side as the clamping piece 18 and the handle 21 is located above the clamping piece 18. The staff can use the handle 21 to pull out the outer cage frame 1;

[0044] Specifically, the base 5 is fixed on the experimental platform. When the cushioning layer 17 needs to be removed or replaced, the lifting hook 12 is inserted into the slot 13 to fix the first supporting plate 3, and then the handle 21 is pulled outward. The handle 21 drives the outer cage frame 1 and the first supporting plate 3 to move, and then the second supporting plate 6 is exposed from under the first supporting plate 3. When the placement groove 16 is completely exposed, the cushioning layer 17 laid in the placement groove 16 is taken out, and a new cushioning layer 17 is laid in the placement groove 16. The outer cage frame 1 and the first supporting plate 3 can be pushed back by the handle 21. The replacement is efficient and hygienic.

[0045] Embodiment 2

[0046] like Figure 1-Figure 7 As shown, this embodiment is improved on the basis of the first embodiment as follows: Further, as Figure 1 , Figure 4 and Figure 5 As shown, a limited slide rail 22 is symmetrically provided inside the outer cage frame 1, and the baffle plate 2 is divided into an upper horizontal portion 23, a connecting portion 24 and a lower horizontal portion 25. Both sides of the upper horizontal portion 23 are slidably connected to the limited slide rail 22, and a side of the outer cage frame 1 close to the upper horizontal portion 23 is provided with an avoidance groove 26, and the diameter of the avoidance groove 26 is adapted to the upper horizontal portion 23;

[0047] like Figure 5 and 7 As shown, the height of the upper horizontal portion 23 is higher than the lower horizontal portion 25 and is connected by a connecting portion 24. The lower horizontal portion 25 and the connecting portion 24 are fixedly connected with the same partition plate 27. The partition plate 27 divides the lower horizontal portion 25 into a material storage area 28 and a water storage area 29. The staff can place the feed bags to be used horizontally on the material storage area 28 and the water storage area 29 to prevent items from piling up on the experimental platform. A first limiting plate 30 and a second limiting plate 31 are fixedly connected to the inside of the outer cage frame 1 on one side close to the lower horizontal portion 25. The partition plate 27 and the lower horizontal portion 25 are respectively abutted against the first limiting plate 30 and the second limiting plate 31. The first limiting plate 30 and the second limiting plate 31 are set to limit and fix the baffle plate 2 to prevent animals from running out.

[0048] Further, such as Figure 5 As shown, a gripping groove 32 is provided on the partition plate 27 to facilitate the staff to grip the partition plate 27 .

[0049] Specifically, when an animal needs to be placed in the outer cage frame 1 or taken out from the outer cage frame 1, the staff holds the partition plate 27 through the gripping groove 32 and pushes the partition plate 27 to make the upper horizontal portion 23 extend along the avoidance groove 26. At this time, the gap between the lower horizontal portion 25 and the outer cage frame 1 increases, and the animal can be placed or taken out.

[0050] In summary, the workflow of the utility model is:

[0051] The base 5 is fixed on the experimental platform, and the staff holds the partition plate 27 through the grasping groove 32 and pushes the partition plate 27 to make the upper horizontal portion 23 extend along the avoidance groove 26. At this time, the gap between the lower horizontal portion 25 and the outer cage frame 1 is increased, and the animal is placed in the outer cage frame 1 through the gap. After the placement is completed, the extended upper horizontal portion 23 is pushed back to block the upper end opening of the outer cage frame 1;

[0052] During the breeding process, when the bedding layer 17 needs to be removed or replaced, the lifting hook 12 is inserted into the slot 13 to fix the first supporting plate 3, and then the handle 21 is pulled outward. The handle 21 drives the outer cage frame 1 and the first supporting plate 3 to move, and then the second supporting plate 6 is exposed from under the first supporting plate 3. When the placement groove 16 is completely exposed, the bedding layer 17 laid in the placement groove 16 is taken out, and a new bedding layer 17 is laid in the placement groove 16, and the outer cage frame 1 and the first supporting plate 3 are pushed back by the handle 21.

[0053] The above different embodiments can be combined, replaced and used in conjunction with each other.
