Description

Technical Field

[0001] This utility model specifically relates to a laboratory mouse rearing rack with an odor isolation structure. Background Technology

[0002] In the field of laboratory animal science, the control of the housing environment for laboratory mice is crucial to the accuracy of experimental results and animal welfare.

[0003] Traditional mouse rearing racks often use open cage designs, allowing odors such as ammonia and hydrogen sulfide from mouse excrement to directly diffuse into the laboratory environment. Some racks have odor-isolating panels around the perimeter with exhaust vents to remove internal odors. However, these structures are usually integrated with the rack, requiring frequent cleaning and replacement of the panels and exhaust vents to maintain cleanliness. Fixed structures, on the other hand, result in longer maintenance times and lower efficiency, leading to increased mouse rearing costs.

[0004] Therefore, it is necessary to invent a laboratory mouse housing with an odor isolation structure to solve the above problems. Utility Model Content

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-4 The experimental mouse rearing rack shown has an odor isolation structure, comprising a rearing rack 2 composed of multiple isolation frames 1, wherein the multiple isolation frames 1 are fixed by multiple support rods 11;

[0030] Specifically, the front support rod 11 of the isolation frame 1 is provided with mounting holes 12, and isolation plates 3 are installed in multiple mounting holes 12;

[0031] Specifically, a splicing component 4 is installed on the side support rod 11 of the isolation frame 1. The splicing component 4 assists in the installation of multiple isolation frames 1, and experimental mouse breeding boxes 5 are matched and installed in the multiple isolation frames 1.

[0032] Specifically, the isolation plate 3 has a vent hole 31, and a sealing cover 32 is installed at the vent hole 31.

[0033] In this embodiment, before installation, the T-shaped splicing grooves 41 and splicing blocks 42 of each isolation frame 1 are first checked to ensure they are intact and free from deformation or obstruction by foreign objects. The first isolation frame 1 is fixed to a horizontal mounting surface. Holding the second isolation frame 1, the T-shaped splicing blocks 42 of the side support rod 11 are aligned with the through end of the T-shaped splicing groove 41 of the first frame. Keeping the sides of the two frames parallel, they are pushed in smoothly and at a uniform speed until the splicing blocks are fully embedded in the splicing grooves, completing the rigid connection between the two frames. The above operation is repeated to assemble the required number of isolation frames 1 according to feeding needs, forming the overall feeding rack 2 structure. After installation, all connections are checked for gaps, and there is no loosening or abnormal noise when the frame is shaken.

[0034] Reference Figure 3 The splicing component 4 includes a splicing groove 41 provided on one side support rod 11, and a splicing block 42 matching the splicing groove 41 provided on the adjacent support rod 11. The splicing block 42 is inserted into the splicing groove 41, that is, multiple isolation frames 1 are spliced ​​together to form a feeding rack 2.

[0035] Specifically, the splicing groove 41 and the splicing block 42 are both T-shaped and matched with each other, and the splicing groove 41 and the splicing block 42 have the same length. One end of the splicing groove 41 is through and the other end is sealed.

[0036] Specifically, a positioning groove 13 for connecting the insertion hole 12 is provided on the inner side of the upper and lower support rods 11 on the rear side of the front insertion hole 12, and a fixing groove 14 is provided on the inner side of the rear support rod 11 corresponding to the insertion hole 12. The fixing groove 14 is connected to the positioning groove 13 and the insertion hole 12, and the isolation plate 3 is positioned and fixed by the above-mentioned groove.

[0037] Specifically, the end of the isolation plate 3 is provided with a mounting groove 33, and a rotating handle 34 is installed in the mounting groove 33. The rotating handle 34 rotates in the mounting groove 33. The front support rod 11 is provided with a groove 15 located inside the insertion hole 11. The rotating handle 34 is placed in the groove 15, and the rotating handle 34 as a whole does not exceed the opening of the groove 15.

[0038] Specifically, the inner connection position of the support rods 11 on both sides of the isolation frame 1 is provided with a sealing groove 16, and a sealing strip 6 is installed in the sealing groove 16. The sealing strip 6 is placed on the outer wall of the experimental mouse breeding box 5.

[0039] Reference Figure 4 The outer thread of the sealing cap 32 matches the inner thread of the vent hole 31. The sealing cap 32 is provided with an external connector 35, and the external connector 35 is provided with a connection hole 36.

[0040] In this embodiment, take a suitable size partition plate 3 and rotate the handle 34 until it is perpendicular to the plane of the partition plate 3. Align the insertion hole 12 of the front support rod 11 and insert the end of the partition plate 3 along the positioning groove 13 until the rear end is fully inserted into the fixing groove 14. At this time, rotate the handle 34 back into the mounting groove 33 and form a surface contact with the groove 15 of the support rod 11. Gently push the partition plate 3 to confirm that there is no looseness, and the installation of a single partition plate is completed. Repeat the operation to install all partition plates 3 to form an independent feeding unit.

[0041] In this embodiment, before placing the experimental mouse housing 5 into the isolation frame 1, check whether the sealing strip 6 in the sealing groove 16 is intact; if damaged, replace it immediately. Slowly push the housing into the frame, ensuring that the outer wall of the housing fits tightly against the sealing strip. Then, install the sealing cap onto the vent hole via a threaded connection. If a ventilation system needs to be connected, a silicone tube can be connected through the connection hole 36 of the external connector 35.

[0042] In this embodiment, it takes only 28 minutes for 3 operators to assemble a 10-unit feeding rack. The T-shaped structure of the splicing components ensures high positioning accuracy and minimal overall vertical deviation after assembly. A single frame can support a 5kg feeding box, and after stacking 5 layers of frames, the maximum deformation is less than 0.3 mm, with no stress cracking at the splicing points, meeting the needs of long-term feeding.

[0043] In this embodiment, the time required for a single person to load and unload the isolation panel is less than 8 seconds. The rotating handle design reduces the operating force by 60% and eliminates the need for tools. In the event of a sudden power outage, the isolation panel can be quickly disassembled, allowing for natural ventilation through the vent holes to prevent oxygen deprivation in the mice.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
