Description

Technical Field

[0001] The utility model relates to the technical field of biological experimental devices, in particular to a mouse breeding cage rack. Background Technique

[0002] Generally, the currently used cage racks are provided with multiple groups of pallets on the columns to stack the cages to improve the space utilization rate. However, in the case of high-density breeding, the ventilation efficiency is poor, and the waste generated by animals is prone to accumulate ammonia, which has a stimulating effect on the respiratory systems of animals and experimental personnel, and may even cause the death of animals in the cage boxes in severe cases. Therefore, many cages are equipped with air pipes to form a circulable and clean air inside the cages.

[0003] However, most of the current pallets adopt a fixed design, or even if they are adjustable, the adjustment process is extremely cumbersome, requiring a lot of time and manpower. This inconvenience is particularly obvious when docking the air pipes, which not only increases the operation difficulty, but may also cause the failure of air pipe docking due to improper adjustment, further affecting the experimental progress. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to solve at least one of the above-mentioned technical problems.

[0005] The solution of the utility model to solve its technical problem is: it includes a cage rack body, a crossbeam group, a connecting piece, a mouse cage and a ventilation mechanism. The ventilation mechanism is arranged on the cage rack body. There are multiple crossbeam groups, and each crossbeam group includes two first crossbeams arranged on the same horizontal plane. All the crossbeam groups are arranged vertically. The first crossbeams are arranged on the cage rack body. The mouse cage is hung on the two first crossbeams of a crossbeam group. There are multiple connecting pieces, and both ends of each first crossbeam are respectively fixedly connected to two of the connecting pieces in a one-to-one correspondence. Multiple card slots are arranged on the cage rack body, and the connecting pieces are detachably fixedly connected to the card slots through bolts.

[0006] The beneficial effects of the utility model are: the design of the cage rack body takes into account both the structural strength and the lightweight requirement, making the cage rack easy to carry and install; the crossbeam group adopts an adjustable design and can be flexibly adjusted according to different models of mouse cages to ensure that the mouse cages are firmly hung; the connecting pieces are fixed by bolts, realizing the tight connection between the first crossbeam and the cage rack body, which is convenient for disassembly and assembly; the ventilation mechanism provides sufficient fresh air inside the cage through air circulation, effectively improving the cage environment and reducing the risk of disease transmission.

[0007] The modular design makes the cage rack easy to assemble and disassemble. The ventilation mechanism provides a good living environment for laboratory mice, reduces the disease incidence rate, and ensures the smooth progress of the experiment. The adjustable crossbeam group increases the applicability of the cage rack. The adjustable connecting piece makes the hanging of the mouse cage more stable without shaking, providing a strong guarantee for the accuracy of experimental data.

[0008] As a further improvement of the above technical solution, the cage rack body includes multiple groups of frameworks. Each group of frameworks includes four second crossbeams, four connecting pipes, and four columns distributed in a rectangular array. The connecting pipes are used to connect the tops and bottoms of two adjacent columns in the front and back, and the second crossbeams are used to connect the tops and bottoms of two adjacent columns on the left and right. A diagonal beam coplanar with the second crossbeam is also fixedly connected between two adjacent columns in the front and back.

[0009] As the beneficial effect of the further improvement of the above technical solution, the second crossbeam and the connecting pipe are connected to form a stable rectangular framework, providing a solid base for the entire cage rack. The diagonal beam further enhances the structural stability. When subjected to external forces, through its inclination angle, part of the horizontal force is converted into a vertical force, effectively reducing the stress burden on the columns, and achieving the structural stability, load-bearing capacity, and aesthetics.

[0010] As a further improvement of the above technical solution, the card slots are distributed vertically on the outer wall of the column, and the card slots are bolted to the connecting pieces.

[0011] As the beneficial effect of the further improvement of the above technical solution, the card slots provide a precise positioning function for the connecting pieces, enhance the structural stability, improve the construction efficiency and installation quality, and also provide convenient conditions for subsequent maintenance and upgrading work. The card slots are distributed vertically, and the spacing of the connecting pieces can be adjusted according to actual needs during installation, and appropriate card slots can be selected for installation.

[0012] As a further improvement of the above technical solution, the first crossbeam is an angle steel, and through holes are provided on the top surface of the first crossbeam, and the through holes are bolted to the connecting pieces.

[0013] As the beneficial effect of the further improvement of the above technical solution, the L-shaped cross-section of the angle steel provides good bending and torsion resistance, making the structure more stable. The angle steel has high strength and stiffness, can bear large loads. The cost of the angle steel is relatively low, and it is easy to mass-produce, with high cost performance.

[0014] As a further improvement of the above technical solution, the connecting member includes a connecting portion, an upper wing portion and a lower wing portion. Two first straight slot holes are provided on the connecting portion, and the first straight slot holes are bolted to the card slots. A second straight slot hole is provided on the upper wing portion, and a third straight slot hole is provided on the lower wing portion. The bottom surface of the top plate of the first cross beam abuts against the top surface of the upper wing portion, and the through hole, the second straight slot hole and the third straight slot hole are bolted together.

[0015] As the beneficial effect of the further improvement of the above technical solution, the straight slot holes can be conveniently matched with other components, simplify the assembly process, provide good matching performance, ensure the correct alignment between components, and the modular design enables the components to be universal and there is no need to distinguish directions during use.

[0016] As a further improvement of the above technical solution, there are multiple squirrel cages, and each squirrel cage is hung on two adjacent first cross beams in the horizontal direction. The ventilation mechanism includes multiple intake pipes and an intake main pipe. The intake ends of all the intake pipes are respectively connected to the intake main pipe, and the outlet ends of all the intake pipes are correspondingly connected to the inside of the squirrel cages. The intake pipes are arranged between two adjacent columns on the left and right.

[0017] As the beneficial effect of the further improvement of the above technical solution, the intake main pipe is used to supply air to all the intake pipes. Such a layout not only makes full use of the space but also ensures that air can be evenly and quickly distributed throughout the area. The parallel operation of multiple intake pipes ensures that air can evenly cover the entire area, avoiding problems such as local oxygen deficiency or poor air flow. The modular design makes the replacement and maintenance of the intake pipes simple and fast, reducing the maintenance cost and time.

[0018] As a further improvement of the above technical solution, multiple air outlet ends communicating with the inside of the air pipe are provided on the intake pipe, and a nozzle device is provided on the air outlet end. One end of the nozzle device is clamped on the air outlet end, and the other end is tightly connected and matched with the squirrel cage for inputting gas into the squirrel cage.

[0019] As the beneficial effect of the further improvement of the above technical solution, the nozzle device is a device with a self-closing function. During use, the nozzle device is inserted into the inside of the cage box. The cage box will exert a certain thrust on the nozzle device to ensure that the nozzle device can smoothly introduce air into the cage box. When the cage box is detached, the original thrust applied to the nozzle device will disappear, and the nozzle device will automatically reset to prevent air from continuing to pass through, thus realizing the self-closing function of the nozzle. Ensure that after the cage box is detached, the nozzle can quickly self-close, and then achieve the effect of timely and comprehensive leakage prevention of the air in the air pipe.

[0020] As a further improvement of the above technical solution, an air inlet channel and an air outlet channel are provided on the squirrel cage. The air outlet channel is connected to a filtering device, which is used to filter the gas discharged from the air outlet channel. The air nozzle device is inserted into the air inlet channel so that the gas output by the air nozzle device can enter the squirrel cage through the air inlet channel.

[0021] As the beneficial effect of the further improvement of the above technical solution, the air inlet channel and the air outlet channel ensure the effective exchange of gas in the squirrel cage, ensure the gas fluidity, improve the efficiency and accuracy of gas exchange. The efficient gas exchange can significantly reduce the concentration of harmful gases in the squirrel cage and effectively improve the air quality in the squirrel cage, providing a healthier and safer living environment for experimental animals.

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model, the drawings required for use in the above description of the embodiments are briefly described. Obviously, the described drawings are only a part of the embodiments of the present utility model, not all embodiments. Those skilled in the art can also obtain other design solutions and drawings based on these drawings without creative efforts.

[0028] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model. In addition, all the connection / linkage relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the formation of a more optimal connection structure by adding or reducing connection accessories according to specific implementation situations. Each technical feature in the present utility model can be interactively combined without conflicting with each other.

[0029] Generally, the currently used cage racks are usually provided with multiple groups of trays on the columns to stack the cages to improve the space utilization rate. However, in the case of high-density breeding, the ventilation efficiency is poor, and the waste generated by animals is likely to accumulate ammonia, which has a stimulating effect on the respiratory systems of animals and experimental personnel, and may even cause the death of animals in the cage box in severe cases. Therefore, many cages are equipped with air pipes to form a recyclable and clean air inside the cages.

[0030] However, most of the current trays adopt a fixed design, or even if they are adjustable, the adjustment process is extremely cumbersome and requires a lot of time and manpower. This inconvenience is particularly obvious during the docking of the air pipes, which not only increases the operation difficulty but also may lead to the failure of the air pipe docking due to improper adjustment, further affecting the experimental progress.

[0031] Therefore, a mouse breeding cage rack, referring to Figures 1 to 4 , includes a cage rack body 1, a crossbeam group 22, a connector 3, a mouse cage 20 and a ventilation mechanism 4. The ventilation mechanism 4 is arranged on the cage rack body 1. A plurality of crossbeam groups 22 are provided. Each crossbeam group 22 includes two first crossbeams 2 arranged on the same horizontal plane. All the crossbeam groups 22 are arranged vertically. The first crossbeams 2 are arranged on the cage rack body 1. The mouse cage 20 is hung on the two first crossbeams 2 of a crossbeam group 22. A plurality of connectors 3 are provided. The two ends of each first crossbeam 2 are respectively and correspondingly fixedly connected to two connectors 3. A plurality of card slots 9 are provided on the cage rack body 1. The connector 3 is detachably fixedly connected to the card slot 9 through a bolt.

[0032] The design of the cage rack body 1 takes into account both structural strength and lightweight requirements, making the cage rack easy to carry and install; the first cross beam 2 adopts an adjustable design and can be flexibly adjusted according to different models of mouse cages 20 to ensure that the mouse cages 20 are firmly hung; the connecting piece 3 is fixed by bolts, realizing a tight connection between the first cross beam 2 and the cage rack body 1 and facilitating disassembly and assembly; the ventilation mechanism 4 provides sufficient fresh air in the cage through air circulation, effectively improving the cage environment and reducing the risk of disease transmission.

[0033] The modular design makes the cage rack easy to assemble and disassemble. The ventilation mechanism 4 provides a good living environment for the experimental mice, reduces the disease incidence rate, and ensures the smooth progress of the experiment; the adjustable first cross beam 2 increases the applicability of the cage rack; the adjustable connecting piece 3 makes the hanging of the mouse cage 20 more stable without shaking, providing a strong guarantee for the accuracy of experimental data.

[0034] The cage rack may shake due to the running of the mice. Thus, in one embodiment, the cage rack body 1 includes multiple groups of frames. Each group of frames includes four second cross beams 6, four connecting pipes 7, and four columns 5 distributed in a rectangular array. The connecting pipes 7 are used to connect the top and bottom ends of two adjacent columns 5 in the front and back, and the second cross beams 6 are used to connect the top and bottom ends of two adjacent columns 5 on the left and right. A diagonal beam 8 coplanar with the second cross beam 6 is also fixedly connected between two adjacent columns 5 in the front and back. The second cross beam 6 and the connecting pipe 7 are connected to form a stable rectangular frame, providing a solid base for the entire cage rack. The diagonal beam 8 further enhances the structural stability. When subjected to an external force, through its inclination angle, part of the horizontal force is converted into a vertical force, thus effectively reducing the stress burden on the columns 5 and realizing the structural stability, load-bearing capacity, and aesthetics.

[0035] The mouse cage 20 is hung on two first cross beams 2 of a cross beam group 22, and it is necessary to ensure that the two first cross beams 2 are arranged on the same horizontal plane. Thus, in one embodiment, the card slots 9 are vertically distributed on the outer wall of the column 5, and the card slots 9 are bolt-connected to the connecting piece 3. The card slots 9 provide a precise positioning function for the connecting piece 3, enhance the structural stability, improve the construction efficiency and installation quality, and also provide convenient conditions for subsequent maintenance and upgrade work; the installation part of the connecting piece 3 is slidably connected to the side wall of the column 5, and the card slots 9 on the column 5 are vertically distributed. During installation, the distance of the connecting piece 3 can be adjusted according to actual needs, and the installation part is bolt-connected to a suitable card slot 9.

[0036] The squirrel cage 20 is hung on the first cross beam 2. It is necessary to comprehensively consider cost and strength when selecting the material of the first cross beam 2. Thus, in one embodiment, the first cross beam 2 is an angle steel. A through hole is provided on the top surface of the first cross beam 2, and the through hole is bolted to the connecting member 3. The L-shaped cross section of the angle steel provides good bending and torsional resistance, making the structure more stable. The angle steel has high strength and stiffness, can bear large loads, has a relatively low cost, and is easy to mass-produce, with high cost performance.

[0037] The connecting member 3 needs to be connected to the column 5 and the first cross beam 2 simultaneously to provide a stable node. Thus, in one embodiment, the connecting member 3 includes a connecting portion 10, an upper wing portion 11, and a lower wing portion 12. Two first straight slot holes 13 are provided on the connecting portion 10, and the first straight slot holes 13 are bolted to the card slot 9. A second straight slot hole 14 is provided on the upper wing portion 11, and a third straight slot hole 15 is provided on the lower wing portion 12. The bottom surface of the top plate of the first cross beam 2 abuts against the top surface of the upper wing portion 11, and the through hole, the second straight slot hole 14, and the third straight slot hole 15 are bolted together. The straight slot holes can be conveniently matched with other components, simplify the assembly process, provide good matching performance, ensure the correct alignment between components, and the modular design makes the components universal and eliminates the need to distinguish directions during use.

[0038] In the case of high-density breeding with poor ventilation efficiency, it will have an adverse impact on animal breeding. Thus, in one embodiment, there are multiple squirrel cages 20, and each squirrel cage 20 is hung on two adjacent first cross beams 2 in the horizontal direction. The ventilation mechanism 4 includes multiple intake pipes 16 and an intake main pipe 17. The intake ends of all the intake pipes 16 are respectively connected to the intake main pipe 17, and the outlet ends 18 of all the intake pipes 16 are in one-to-one correspondence and communicate with the inside of the squirrel cage 20. The intake pipes 16 are arranged between two adjacent columns 5 on the left and right. The intake main pipe 17 is used to supply air to the multiple intake pipes 16. Such a layout not only makes full use of the space but also ensures that the air can be evenly and quickly distributed throughout the area. The parallel operation of the multiple intake pipes 16 ensures that the air can evenly cover the entire area, avoiding problems such as local oxygen deficiency or poor air flow. The modular design makes the replacement and maintenance of the intake pipes 16 simple and fast, reducing the maintenance cost and time.

[0039] After the air supply pipe is connected to the nozzle, the air in the air supply pipe starts to be delivered into the cage box. When it is necessary to separate the air supply pipe from the cage box, the nozzle on the air supply pipe must be plugged immediately after being detached from the cage box, otherwise air leakage in the air supply pipe may occur. Thus, in one embodiment, the intake pipe 16 is provided with a plurality of air outlet ends 18 communicating with the inside of the pipe, and a nozzle device 19 is provided on the air outlet end 18. One end of the nozzle device 19 is snap-connected to the air outlet end 18, and the other end is in close connection and cooperation with the mouse cage 20 for inputting gas into the mouse cage 20. The nozzle device 19 is a device with a self-closing function. During use, the nozzle device 19 is inserted into the inside of the cage box. The cage box applies a certain pushing force to the nozzle device 19 to ensure that the nozzle device 19 can smoothly deliver air into the cage box. When the cage box is detached, the original pushing force applied to the nozzle device 19 disappears, and the nozzle device 19 automatically resets to prevent air from continuing to pass through, thereby realizing the self-closing function of the nozzle. It is ensured that after the cage box is detached, the nozzle can quickly self-close, thereby achieving the effect of timely and comprehensive leakage prevention of the air in the pipe.

[0040] Ensuring gas fluidity can improve the efficiency of gas exchange. Thus, in one embodiment, the mouse cage 20 is provided with an intake channel 21 and an outlet channel. The outlet channel is connected to a filtering device for filtering the gas discharged from the outlet channel. The nozzle device 19 is inserted into the intake channel 21 so that the gas output by the nozzle device 19 can enter the mouse cage 20 through the intake channel 21. The intake channel 21 and the outlet channel ensure the effective exchange of gas in the mouse cage 20, ensure gas fluidity, and improve the efficiency and accuracy of gas exchange. Efficient gas exchange can significantly reduce the concentration of harmful gases in the mouse cage 20 and effectively improve the air quality in the mouse cage 20, providing a healthier and safer living environment for experimental animals.

[0041] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
