Description

Technical Field

[0001] This utility model relates to the field of mouse cages, specifically a mouse cage for laboratory mice. Background Technology

[0002] Laboratory mice are a special type of mouse widely used in scientific research. They are widely used in many fields such as biomedical research. Their breeding environment has an important impact on the accuracy and reliability of experimental results. Laboratory mice are indispensable in the drug development process. Before a new drug is used in human clinical trials, pharmacodynamic and toxicological tests are usually conducted on laboratory mice. Mouse cages are the places used to raise mice.

[0003] Existing mouse cages often have some problems: such as unreasonable spatial layout, unclear division of activity area and feeding space, which leads to restricted mouse activity and abnormal behavior; they are difficult to clean, making it difficult to clean feces and change bedding in a timely manner, which affects the daily life of mice. Therefore, a new type of experimental mouse cage is proposed to solve the above problems. Utility Model Content

[0027] 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 protection scope of the present utility model.

[0028] In the embodiments, by Figure 1-5 The present invention discloses a laboratory mouse cage, comprising a cage body 1, a cover plate 2 on the top of the cage body 1 by means of a latch, a clearance groove inside the cover plate 2, a baffle 3 inside the clearance groove that penetrates the cover plate 2 and extends into the cage body 1, a first fixing plate 4 fixedly connected to the top of the baffle 3 by means of fasteners, a through groove inside the cage body 1, a feeding trough 5 inside the cage body 1, a limiting plate 6 fixedly connected to the outside of the feeding trough 5, a second fixing plate 7 fixedly connected to the outside of the limiting plate 6 by means of fasteners, a support frame 8 fixedly connected to the inside of the cage body 1 by means of fasteners, a plurality of ventilation grooves inside the cage body 1, and a glass observation window 9 inside the cage body 1.

[0029] The main body 1 of the rat cage has two sliding grooves inside, and the front and rear sides of the baffle 3 are fixedly connected with sliding plates 10 that are slidably connected to the two sliding grooves respectively.

[0030] In this embodiment, during actual use, the baffle 3 can pass through the cover plate 2 and enter the mouse cage body 1. The baffle 3 divides the interior of the mouse cage body 1 into left and right parts. The sliding of the slide plate 10 and the slide groove restricts the movement direction of the baffle 3.

[0031] The cover plate 2 has a first threaded hole inside, and the first fixing plate 4 has a first bolt knob 11 that is threadedly connected to the first threaded hole inside.

[0032] In this embodiment, during actual use, the first fixing plate 4 and the cover plate 2 can be relatively fixed by tightening the first bolt knob 11 and the first threaded hole. The cover plate 2 and the mouse cage body 1 are locked and fixed by the latch. Then the baffle 3 below the first fixing plate 4 will stably separate the inside of the mouse cage body 1.

[0033] The rat cage body 1 has a second threaded hole inside, and the second fixing plate 7 has a second bolt knob 12 that is threaded to the second threaded hole.

[0034] In this embodiment, during actual use, the feeding trough 5 can store feed or water, and the second bolt knob 12 can fix the second fixing plate 7 to the main body of the rat cage 1, thereby fixing the feeding trough 5. Removing the feeding trough 5 can fill it with feed or water and also clean the inside of the main body of the rat cage 1.

[0035] The support frame 8 and the feeding trough 5 are located on the left and right sides of the baffle 3, respectively, and the cross-sections of the support frame 8 and the feeding trough 5 are both concave.

[0036] In this embodiment, during actual use, padding material can be placed inside the support frame 8 to facilitate the movement of the mice. The baffle 3 separates the support frame 8 from the feeding trough 5, so that the mice can be separated and not affect the other side.

[0037] The support frame 8 has a third threaded hole inside, and the main body of the rat cage 1 has a third bolt knob 13 that is threadedly connected to the third threaded hole inside.

[0038] In this embodiment, the support frame 8 can also be disassembled during actual use. The bottom wall of the mouse cage body 1 located on the left side of the baffle 3 is hollowed out, while the support frame 8 provides a standing position for the mouse. At the same time, the support frame 8 can be removed from its bottom by unscrewing the third bolt knob 13, so that the padding inside the support frame 8 can be cleaned or replaced.

[0039] Working principle:

[0040] When mice are placed in the cage for rearing, the cover 2 can be unlocked and lifted upwards to open, allowing the mice to be placed inside the cage body 1. Under normal circumstances, the mice can move freely inside the cage body 1. The ventilation slots and glass observation windows 9 inside the cage body 1 allow for ventilation and observation of the mice, respectively. When it is necessary to replace the bedding in the support frame 8, the baffle 3 can be inserted while the mice are eating or when the mice are driven and lured to the right side. At this time, the third bolt knob 13 can be removed to remove the support frame 8 for bedding replacement. The same applies to replacing or cleaning the feed in the feeding trough 5. By driving or luring the mice to the inside left side of the cage body 1, the feed can be replaced by removing the second bolt knob 12.
