Description

Technical Field

[0001] This utility model relates to the field of rat and mouse breeding cages, specifically a rat and mouse independent ventilation cage. Background Technology

[0002] The rat and mouse ventilation cage is an SPF (specific pathogen-free) cage purification and ventilation feeding device designed specifically for small rodent laboratory animals such as rats and mice. It is suitable for the breeding, reproduction, preservation and various short-term animal experiments of SPF animals, especially for raising defective animals and transgenic animals. It is an indispensable piece of equipment in laboratory animal centers and breeding centers.

[0003] However, the current independent ventilation cages for mice and rats still have some shortcomings. For example, the disassembly and assembly steps of the existing independent ventilation cages for mice and rats are relatively cumbersome, which means that when staff need to replace or clean the ventilation cages, they need to spend a long time disassembling and assembling the cages, which interferes with the efficiency of staff replacement and cleaning, and thus has certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide an independent ventilation cage for rats and mice. Utility Model Content

[0005] The purpose of this invention is to provide an independent ventilation cage for rats and mice to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rat and mouse independent ventilation cage, comprising a support plate and a rat cage. The support plate has symmetrically mounted casters at its bottom, and longitudinal partitions are fixedly mounted at equal intervals on its top. A transverse partition is fixedly connected to the top of the longitudinal partitions. A top plate is parallel to the top of the support plate, and positioning strips are fixedly mounted at equal intervals on the top of the transverse partitions. The rat cage is movably mounted on the top of the transverse partitions, and a handle is fixedly mounted on the outside of the rat cage. A sealing assembly is snapped onto the top of the rat cage, and an adjustment assembly is movably connected to the top of the sealing assembly. An exhaust pipe is fixedly connected to the top of the sealing assembly, and a pipe mounting bracket is mounted on the outer surface of the exhaust pipe. A gas distribution pipe is fixedly mounted on the top of the sealing assembly.

[0007] Furthermore, the top of the longitudinal partition plate is fixedly connected to the bottom of the transverse partition plate, and the bottom of the longitudinal partition plate is fixedly connected to the top of the support plate, and the transverse partition plate forms a fixed structure with the support plate through the longitudinal partition plate.

[0008] Furthermore, the sealing assembly includes a sealing cap, a guide groove, and a T-shaped slider, with the guide groove provided at the bottom of the sealing cap and the T-shaped sliders symmetrically installed on the sides of the sealing cap.

[0009] Furthermore, the side of the sealing cover is fixedly connected to the inner side of the T-shaped slider, and the sealing cover forms a sliding structure with the longitudinal partition plate through the T-shaped slider.

[0010] Furthermore, the adjustment assembly includes a connecting rod, a knob, a pulley, and a transmission belt. The knob is fixedly installed at the bottom of the connecting rod, and the pulley is fixedly connected to the outer surface of the connecting rod. The transmission belt is movably connected to the outer surface of the pulley.

[0011] Furthermore, the bottom of the connecting rod is fixedly connected to the top of the knob, and the end of the connecting rod is rotatably connected to the inside of the transverse partition plate, and the knob forms a rotating structure with the transverse partition plate through the connecting rod.

[0012] Furthermore, the adjusting assembly also includes a threaded cylinder, a threaded extension rod, and a connecting seat. The threaded cylinder is internally threaded with the threaded extension rod, and the bottom of the threaded extension rod is fixedly mounted with the connecting seat. The bottom of the connecting seat is fixedly connected to the top of the sealing cover, while the upper end of the threaded cylinder is rotatably connected to the interior of the transverse partition plate.

[0013] Furthermore, there are two pulleys, which are fixedly mounted on the outer surfaces of the connecting rod and the threaded cylinder, and are movably connected to the inner surfaces of both ends of the transmission belt.

[0014] This invention provides an independent ventilation cage for rats and mice, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of pulleys and transmission belts, enables the threaded cylinder to rotate synchronously at the bottom of the horizontal partition plate when the operator rotates the connecting rod by turning the knob. At this time, through the fixed connection of the connecting seat, the threaded cylinder can drive the threaded extension rod to move up and down along the inner surface of the threaded cylinder when rotating, thereby achieving the purpose of quickly adjusting the height of the sealing component. This provides convenience for the operator to disassemble and assemble the rat cage, thus avoiding the situation where the operator needs to spend a long time disassembling and assembling the cage when replacing and cleaning the ventilation cage, which would interfere with the operator's replacement and cleaning efficiency.

[0016] 2. This utility model uses a T-shaped slider to allow the operator to move the sealing cover stably up and down along the inner surface of the longitudinal partition when rotating the adjustment component. Then, with the cooperation of the guide groove, the sealing cover can automatically complete the locking and sealing process when it descends, thus completing the quick installation of the rat cage. Furthermore, the positioning strip allows the operator to initially position and fix the rat cage when it is placed on top of the support plate and the transverse partition, which facilitates the subsequent adjustment of the sealing component for lowering and sealing.

The end is rotatably connected to the interior of the transverse partition plate 4, and the knob 102 forms a rotating structure with the transverse partition plate 4 through the connecting rod 101. The knob 102 and the transverse partition plate 4, which are configured as a rotating structure, make it easy for the staff to adjust the height of the sealing assembly 9. The outer surface of the connecting rod 101 is fixedly connected to the pulley 103, and the outer surface of the pulley 103 is movably connected to the transmission belt 104.

[0023] like Figures 1-3As shown, casters 2 are symmetrically installed on the bottom of the support plate 1, and longitudinal partition plates 3 are fixedly installed at equal intervals on the top of the support plate 1. A transverse partition plate 4 is fixedly connected to the top of the longitudinal partition plate 3.

The adjusting assembly 10 also includes a threaded cylinder 105, a threaded extension rod 106, and a connecting seat 107. The inner... The threaded extension rod 106 is connected to the threaded part. There are two pulleys 103. The two pulleys 103 are fixedly installed on the outer surfaces of the connecting rod 101 and the threaded cylinder 105, respectively.

[0024] In summary, this independent ventilation cage for mice and rats was first based on... Figures 1 to 3 As shown in the diagram, the worker grasps the handle 8 and lifts the cleaned rat cage 7 using it. The rat cage 7 is then placed on top of the support plate 1 or the transverse partition plate 4. The positioning strip 6 provides initial positioning of the rat cage 7. Next, the worker grasps the knob 102, which rotates the connecting rod 101 at the bottom of the transverse partition plate 4. The pulley 103 and the transmission belt 104 work together to cause the connecting rod 101 to rotate synchronously with the threaded cylinder 105 at the bottom of the transverse partition plate 4. The connecting seat 107 secures the threaded cylinder 105, allowing it to rotate and drive the threaded extension rod 1... 06 extends and moves along the inside of the threaded cylinder 105. At this time, the sliding of the T-shaped slider 93 causes the sealing cover 91 to move downward along the inner surface of the longitudinal partition plate 3. Then, with the cooperation of the guide groove 92, the sealing cover 91 can be quickly snapped onto the upper outer surface of the rat cage 7 when the operator rotates the adjustment component 10, thereby completing the automatic sealing work. When the ventilation cage is in use, fresh air is independently injected into the rat cage 7 connected to the end through the air distribution pipe 13 to achieve independent ventilation. Then, with the cooperation of the exhaust pipe 11, the exhaust gas generated in each rat cage 7 is discharged uniformly to ensure that the air in each ventilation cage does not cross-ventilate.
