Description

Technical Field

[0001] This utility model relates to the field of rodent breeding technology, specifically a multi-configuration breeding cage for rodents. Background Technology

[0002] Rodents, such as mice and rats, have become indispensable experimental animal models in fields such as biomedical research, drug development, and genetic research due to their many advantages, including short reproductive cycles, high reproductive capacity, clear genetic background, and ease of breeding and management.

[0003] A search revealed a utility model patent with Chinese patent publication number CN214178547U, which discloses a dual-purpose transport and breeding box for rodents, relating to the technical field of animal transport and breeding boxes. It comprises a box body, an upper cover, a lower cover, and a protective net. The box body is composed of the upper and lower cover. Connecting and fixing blocks are respectively provided at the left and right ends of the upper and lower cover, and multiple fastening screws are provided on the connecting and fixing blocks to fix the upper and lower cover together.

[0004] As mentioned above, breeding cages are generally one-piece structures, suitable only for breeding with one male and one female animal, which is quite wasteful of space. Even if some units force the use of one male animal or two to three female animals for breeding in existing breeding cages, although it can improve the efficiency of the cages to some extent, it will lead to adult male or female animals trampling or biting the newborn mice to death, indicating room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a multi-configuration breeding cage for rodents to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-breeding cage for rodents, comprising a cage body, a partition assembly installed inside the cage body, the partition assembly including a partition plate fixedly connected inside the cage body, the partition plate being horizontally positioned and located on one side of the cage body, an avoidance hole being provided inside the partition plate, and an inclined staircase fixedly connected to the bottom of the cage body near the lower part of the partition plate, one end of the top of the staircase extending into the avoidance hole and fixedly connected to the inner wall of one side of the avoidance hole.

[0007] This breeding cage device features a two-layer design, facilitating movement of male animals between the upper and lower levels. The entire device fully meets the needs of multi-breeding, significantly improving breeding efficiency and increasing the survival rate of newborn mice. A partition divides the main body of the cage into two layers, each accommodating one male and one female. Due to the territoriality of female mice and food availability, they will not live on the same layer. The two spaces are connected by a clearance hole, allowing male animals to move between the upper and lower levels via stairs. The entire device fully meets the needs of multi-breeding, i.e., one male and two females, saving on the number of male animals compared to traditional methods, and greatly improving breeding efficiency and the survival rate of newborn mice.

[0008] As a further preferred embodiment of this technical solution, two sewage discharge components are installed inside the cage body, one of which is at the same level as the partition, and the other is at the same level as the bottom inner wall of the cage body.

[0009] As a further preferred embodiment of this technical solution, the sewage discharge assembly includes the same grid plate fixedly connected between the partition and the cage body. A receiving frame is fixedly connected to one side of the bottom outer wall of the partition. The receiving frame is inclined as a whole, and one end of the receiving frame extends to one side of the cage body.

[0010] As a further preferred embodiment of this technical solution, two horizontally arranged limiting rods are fixedly connected inside the receiving frame. The two limiting rods are respectively located at both ends of the receiving frame. The two limiting rods are slidably fitted with the same scraper. The scraper is in contact with the bottom inner wall of the receiving frame. An extension rod is fixedly connected to the upper part of the outer wall of the scraper near the outside. The extension rod is kept at the same level as the receiving frame. A spring is slidably fitted on the outside of each of the two limiting rods. One end of each spring abuts against the side of the scraper near the lower part of the receiving frame, and the other end abuts against the inner wall of the corresponding end of the receiving frame.

[0011] When excrement is discharged onto the top of the grating, it falls through its holes into the receiving frame below, reducing contact between animals and feces and lowering the risk of bacterial infection. Because the receiving frame has a certain inclination, the excrement will slide down the slope. If the excrement sticks to the inside of the receiving frame, when the extension rod is grasped and the scraper is pulled, the spring stress connected to the scraper is overcome and shortened, and then it will slide along the two limit rods. The scraper can then clean up the attached material, saving the slow cleaning process.

[0012] As a further preferred embodiment of this technical solution, two parallel baffles are fixedly connected inside the receiving frame. Both baffles are parallel to the receiving frame and cover the tops of the two limiting rods respectively.

[0013] As a further preferred embodiment of this technical solution, two support columns are fixedly connected to the outer walls on both sides of the cage body.

[0014] As a further preferred embodiment of this technical solution, each of the four support columns has a slot at one bottom end, and each of the four support columns has a plug fixedly connected to the top outer wall, with the four plugs corresponding one-to-one with the four slots.

[0015] This utility model provides a multi-configuration breeding cage for rodents, which has the following beneficial effects:

[0016] (1) By setting up a partition component, the breeding cage device of this utility model is designed as a two-layer structure, which facilitates the movement of male animals between the upper and lower layers. The entire device can fully meet the needs of multi-breeding, greatly improve the breeding efficiency, and increase the survival rate of newborn mice. The cage body is divided into two layers by a partition, and each layer can be used by one male animal and one female animal. Due to the territorial awareness of female mice and food factors, they will not live on the same layer. The two spaces are connected by a clearance hole. Male animals can move between the upper and lower layers through the stairs. The entire device can fully meet the needs of multi-breeding, that is, one male animal and two female animals to breed offspring. It saves the number of male animals compared with the traditional method, and greatly improves the breeding efficiency and increases the survival rate of newborn mice.

[0017] (2) By setting up a sewage discharge component, when the excrement is discharged to the top of the grid plate, it will fall into the receiving frame below through its holes, which can reduce the contact between animals and feces and reduce the risk of bacterial infection. Since the receiving frame has a certain degree of inclination, the excrement will slide down the slope. If the excrement sticks to the inside of the receiving frame, when the extension rod is grasped and the scraper is pulled, the spring stress connected to the scraper is overcome and shortened. Then it will slide along the two limit rods, and the scraper can clean the attached material, saving the slow cleaning process. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 1 As shown in Figure 4, in this embodiment, a multi-configuration breeding cage for rodents includes a cage body 1. A partition component 5 is installed inside the cage body 1. The partition component 5 includes a partition 501 fixedly connected inside the cage body 1. The partition 501 is horizontally positioned and located on one side of the cage body 1. An avoidance hole 502 is provided inside the partition 501. An inclined staircase 503 is fixedly connected to the bottom of the cage body 1 near the lower part of the partition 501. One end of the top of the staircase 503 extends into the avoidance hole 502 and is fixedly connected to the inner wall of one side of the avoidance hole 502.

[0025] The cage body 1 is divided into two layers by a partition 501. Each layer can be used by one male and one female animal. Due to the territoriality of the female mouse and food factors, they will not live on the same layer. The two spaces are connected by a clearance hole 502. The male animal can move between the upper and lower layers through the stairs 503. The whole device can fully meet the needs of multi-breeding, that is, the breeding needs of one male animal and two female animals. It saves the number of male animals compared with the traditional method and greatly improves the breeding efficiency and increases the survival rate of the newborn mice.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, two sewage discharge components 6 are installed inside the cage body 1. One sewage discharge component 6 is at the same level as the partition 501, and the other sewage discharge component 6 is at the same level as the bottom inner wall of the cage body 1.

[0027] The sewage discharge assembly 6 includes the same grid plate 601 fixedly connected between the partition plate 501 and the cage body 1. A receiving frame 602 is fixedly connected to one side of the bottom outer wall of the partition plate 501. The receiving frame 602 is inclined as a whole, and one end of the receiving frame 602 extends to one side of the cage body 1.

[0028] Two horizontally positioned limiting rods 603 are fixedly connected inside the receiving frame 602. The two limiting rods 603 are located at both ends of the receiving frame 602. The two limiting rods 603 are slidably fitted with the same scraper 604. The scraper 604 is in contact with the bottom inner wall of the receiving frame 602. An extension rod 607 is fixedly connected to the upper part of the outer wall of the scraper 604 near the outside. The extension rod 607 is kept at the same level as the receiving frame 602. A spring 605 is slidably fitted on the outside of each of the two limiting rods 603. One end of each spring 605 abuts against the side of the scraper 604 near the lower part of the receiving frame 602, and the other end abuts against the inner wall of the corresponding end of the receiving frame 602.

[0029] Rats have a habit of defecating in designated areas. Through training, they can be guided to defecate in the grid area. When the excrement is discharged to the top of the grid plate 601, it will fall through the holes into the receiving frame 602 below, which can reduce the contact between the animal and the feces and reduce the risk of bacterial infection. Since the receiving frame 602 has a certain degree of inclination, the excrement will slide down the slope. If the excrement sticks to the inside of the receiving frame 602, when the extension rod 607 is grasped and a pulling force is applied to the scraper 604, the stress of the spring 605 connected to the scraper 604 is overcome and shortened. Then it will slide along the two limit rods 603, and the scraper 604 can clean the attached material, saving the slow cleaning process.

[0030] like Figure 3 and Figure 4 As shown, two parallel baffles 606 are fixedly connected inside the receiving frame 602. Both baffles 606 are parallel to the receiving frame 602, and the two baffles 606 cover the top of the two limiting rods 603 respectively, which can prevent the excrement from falling outside the limiting rods 603, thereby ensuring that the scraper 604 can move smoothly.

[0031] like Figure 1 As shown in Figure 2, two support columns 2 are fixedly connected to the outer walls on both sides of the cage body 1.

[0032] Each of the four support columns 2 has a slot 4 at one bottom end, and each of the four support columns 2 has a plug 3 fixedly connected to the top outer wall, with the four plugs 3 corresponding to the four slots 4 one by one.

[0033] The slots 4 at the bottom of the support columns 2 on both sides of the top cage body 1 are fitted onto the outside of the plugs 3 at the top of the support columns 2 on both sides of the bottom cage body 1. With the cooperation of the two, the connected cage body 1 can be kept in a stable state and will not easily loosen.

[0034] This utility model provides a multi-configuration breeding cage for rodents, and its working principle is as follows:

[0035] When the device is in operation, the cage body 1 is divided into two layers by a partition 501. Each layer can be used by one male animal and one female animal. Due to the territoriality of the female mice and food factors, they will not live on the same layer. The two spaces are connected by a clearance hole 502. The male animal can move between the upper and lower layers through the stairs 503. The entire device can fully meet the needs of multi-breeding, that is, the breeding needs of one male animal and two female animals. It saves the number of male animals compared with the traditional method and greatly improves the breeding efficiency and increases the survival rate of the suckling mice.

[0036] Rats have a habit of defecating in designated areas. Through training, they can be guided to defecate in the grid area. When the excrement is discharged to the top of the grid plate 601, it will fall through the holes into the receiving frame 602 below, which can reduce the contact between the animal and the feces and reduce the risk of bacterial infection. Since the receiving frame 602 has a certain degree of inclination, the excrement will slide down the slope. If the excrement sticks to the inside of the receiving frame 602, when the extension rod 607 is grasped and a pulling force is applied to the scraper 604, the stress of the spring 605 connected to the scraper 604 is overcome and shortened. Then it will slide along the two limit rods 603, and the scraper 604 can clean the attached material, saving the slow cleaning process.

[0037] If the breeding room is small, two cages can be stacked vertically. The slots 4 at the bottom of the support columns 2 on both sides of the top cage body 1 are fitted onto the plugs 3 at the top of the support columns 2 on both sides of the bottom cage body 1. With the cooperation of the two, the connected cage body 1 can be kept stable and will not easily loosen.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
