Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of experimental rat culture, in particular to an experimental rat culture cage. BACKGROUND

[0002] Rats are the most commonly used experimental animals in biological experiments. Experimental rats refer to white-coated rats or rats commonly used in physiology, medicine, pharmacy and other disciplines for teaching and research as experimental animals. Experimental rats have been developed into many varieties through long-term selection and directional breeding. Generally, they are divided into two types: ordinary experimental rats and special experimental rats to meet special needs. Special experimental rats include high-cancer rats, low-cancer rats, diabetic rats, and congenital muscular atrophy rats. Some classify experimental rats into inbred lines, mutant lines, outbred and hybrid groups according to different crossbreeding methods and genetic characteristics. Rats have poor self-regulation ability and disease resistance compared to other experimental animals. There are many varieties and strains of rats, each with its own special requirements. Experimental rats in the laboratory need a growing and culture space before the experiment, usually in a rat cage. The existing rat cage is usually a conventional rat cage made of iron wire, with a food box and a water box, and the conventional rat cage is open to the outside air.

[0003] For example, patent number CN202220280100.4, an experimental rat culture cage, has the following disadvantages in actual use:

[0004] The above device can isolate each cultured rat and prevent rats from harming each other due to mixed feeding. However, the operator needs to separately feed water and feed to each feeding space. When there are many cultured rats, feeding takes a long time and is inconvenient to use. SUMMARY

[0005] To improve the problem of long feeding time and inconvenience of use of the experimental rat culture cage, the present application provides an experimental rat culture cage.

[0006] The experimental rat culture cage provided by the present application adopts the following technical scheme:

[0007] An experimental rat culture cage, comprising a multi-cell rotating cage and a rotating base, the multi-cell rotating cage comprising a central cylinder, the upper and lower ends of the central cylinder being fixed with a layer plate, a plurality of equally spaced partition plates being arranged between the two layer plates, a cage door being arranged between each adjacent two partition plates, the cage door and the two side partition plates forming a culture space, the rotating base being arranged at the bottom of the multi-cell rotating cage to provide a rotating effect for the multi-cell rotating cage, and a ring-shaped water tank and a ring-shaped feed tank being arranged on the outside of the central cylinder.

[0008] The annular water tank is fixed outside the central cylinder, and one side of the annular water tank is connected with an extension groove located inside one of the culture spaces.

[0009] The annular feed tank is rotationally arranged outside the central cylinder, and the annular feed tank is placed on the layer plate at the bottom.

[0010] Through the above technical scheme, the annular feed tank and the annular water tank pass through each culture space, and the operator can add water and feed from the culture space where the extension groove is located, and slowly rotate the annular feed tank when adding feed, so that the feed and water can be uniformly placed in each culture space, and feeding is more convenient.

[0011] Preferably, a feeding mechanism for feeding the feed is arranged in one of the culture spaces, the feeding mechanism comprises a support plate fixed on the layer plate, an open-end discharge cylinder is fixed on the support plate, the open end of the discharge cylinder is located above the annular feed tank, a feed hopper is connected above the other end of the discharge cylinder, a discharge auger is rotationally arranged in the discharge cylinder, a rotating handle is connected to the end of the discharge auger, a plurality of first teeth are equally fixed on the surface of the other end of the discharge auger, and a plurality of second teeth are equally fixed on the inner surface of the annular feed tank.

[0015] Preferably, the pull-out plate is made of iron material, and a food blocking plate is arranged between the two pull-out plates, and a magnet strip is fixed on both sides of the food blocking plate.

[0016] Through the above technical scheme, the food blocking plate can isolate the annular water tank and the annular feed tank in the culture space, so that different food can be fed to specific rats when needed, and the experimental requirements are met, and the food blocking plate is fixed by magnetic attraction, which is convenient to disassemble and install.

[0017] Preferably, the door comprises an arc-shaped glass plate and two blocking strips fixed outside the side clamping plates, the inner surfaces of both ends of the arc-shaped glass plate abut against the two blocking strips, a limiting clamping strip is rotationally connected to the blocking strip, and the limiting clamping strip abuts against the outer side of the arc-shaped glass plate.

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1.
