Description

Technical Field

[0001] This utility model relates to the technical field of biological experimental devices, and in particular to an experimental mouse cage rack with high space utilization. Background Technology

[0002] Laboratory mice, rats, and guinea pigs are small laboratory animals used in large quantities in biological research. These animals are typically kept in cages and fed within them. However, because these small animals need to be raised in large numbers, a large number of cages are required, resulting in low stocking densities and occupying a significant amount of space. Furthermore, staff need to water the animals in their cages, which increases their workload and makes using the cages inconvenient; therefore, improvements are needed. Utility Model Content

[0003] To improve space utilization, reduce the space occupied by the mouse cage rack, and facilitate the use of the mouse cage rack, this application provides a laboratory mouse cage rack with high space utilization.

[0004] The experimental mouse cage rack with high space utilization provided in this application adopts the following technical solution: A space-efficient laboratory mouse cage rack includes a base, a support rod, a connecting block, and a connecting rod. The support rod is rotatably mounted on the base, and the connecting block is fixedly mounted on the top of the support rod. Several connecting rods are provided on the side wall of the connecting block, and a frame is provided on the connecting rod. Several cage boxes are provided on the frame.

[0005] By adopting the above technical solution, several frames are set on the side wall of the connecting block, and several cages are set on the frames. The cages are placed at a high position, so that other experimental supplies can be placed on the base, which effectively improves the space utilization rate and reduces the space occupied by the mouse cage frame. During the experiment, the staff can rotate the support rod to operate the cages in different positions, so as to facilitate the operation of the mouse cage frame.

[0006] Preferably, the lower surface of the base is rotatably provided with casters.

[0007] By adopting the above technical solution, the entire rat cage frame can be moved easily, making it even more convenient to use.

[0008] Preferably, the support rod has an air inlet groove, a fan is installed on the outer wall of the support rod, and an air inlet hole communicating with the air inlet groove is opened on the side wall of the support rod. The air outlet end of the fan is communicating with the air inlet hole. The connecting block has an air inlet chamber, which is communicating with the air inlet groove. The connecting rod has an air outlet groove communicating with the air inlet chamber. The surface of the connecting rod has several air outlet holes communicating with the air outlet groove. The cage box is fitted to the side wall of the connecting rod. The side wall of the cage box has ventilation holes corresponding to the air outlet holes. The cage box has several air exchange holes.

[0009] By adopting the above technical solution, external air is drawn into the air inlet slot through the air inlet hole by the fan. The air then flows from the air inlet slot into the air inlet chamber inside the connecting block, and simultaneously flows into the surrounding air outlet slots through the air inlet chamber. Since the air vent and the air outlet are aligned with each other, the airflow in the air outlet slot eventually enters the cage through the air vent, while the gas in the cage is discharged through the ventilation hole, thereby accelerating the airflow in the cage. The airflow helps maintain oxygen balance, prevents laboratory animals from suffocating or suffering physiological damage, and helps stabilize the temperature and humidity in the cage.

[0010] Preferably, a guide block is provided inside the air intake cavity and on the top wall.

[0011] By adopting the above technical solution, the guide block distributes and guides the airflow entering the air intake cavity, which is conducive to the uniform entry of the new shoe space into different air outlet slots.

[0012] Preferably, an air purifier is installed between the air inlet and the fan, and the air purifier is connected to the support rod.

[0013] By adopting the above technical solutions, we can help maintain a dynamic balance of gas exchange, avoid animal stress or microbial growth caused by high temperature and high humidity environments, improve sterilization efficiency, and protect animal health.

[0014] Preferably, a set of mounting plates are symmetrically fixed on the frame, and a mounting block is integrally provided at the end of the mounting plate. The top of the connecting rod is provided with a mounting groove for the mounting block to be inserted and abutted. The mounting groove and the mounting block are mutually compatible.

[0015] By adopting the above technical solution, the frame and connecting rod can be quickly disassembled and assembled by utilizing the cooperation between the mounting slot and the mounting block, thus separating the frame and the connecting rod and facilitating the operation of the cage on the frame.

[0016] Preferably, the side wall of the cage is fixedly provided with a dovetail block, and the top of the connecting rod is provided with a dovetail groove for inserting and engaging the dovetail block.

[0017] By adopting the above technical solution, the dovetail block and the dovetail groove cooperate with each other, making it easy to assemble and disassemble the cage box and the connecting rod. The cage box can be operated separately, which further improves convenience.

[0018] Preferably, a slide rail is provided at the end of the connecting rod away from the connecting block, and an expansion box is slidably mounted on the slide rail. The slide rail and the connecting rod are detachably connected by bolts.

[0019] By adopting the above technical solution, the expansion box can be used to raise experimental animals just like the cage box, which maximizes the space utilization rate. By using the cooperation between the slide rail and the expansion box, the position of the expansion box can be changed, which facilitates the observation of different cage boxes and avoids the expansion box interfering with the cage box.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a base, support rod, connecting block, frame, and cage, several frames are set on the side wall of the connecting block, and several cages are set on the frames. The cages are placed at a high position, so that other experimental supplies can be placed on the base, which effectively improves the space utilization rate and reduces the space occupied by the mouse cage frame. During the experiment, the staff can rotate the support rod to operate the cages in different positions, so as to facilitate the operation of the mouse cage frame. 2. By setting up an air inlet slot, a fan, an air inlet hole, an air inlet chamber, an air outlet slot, an air outlet hole, a ventilation hole, and a ventilation hole, the fan draws external air into the air inlet slot through the air inlet hole. The air then flows from the air inlet slot into the air inlet chamber within the connecting block, and simultaneously flows into the surrounding air outlet slots. Since the ventilation hole and the air outlet hole are aligned with each other, the airflow in the air outlet slot eventually enters the cage through the ventilation hole, while the gas inside the cage is discharged through the ventilation hole, thus accelerating the airflow within the cage. This airflow helps maintain oxygen balance, prevents laboratory animals from suffocating or suffering physiological damage, and helps stabilize the temperature and humidity inside the cage. 3. By setting up mounting plates, mounting blocks, mounting slots, dovetail blocks, and dovetail grooves, the mounting slots and mounting blocks can be used to quickly assemble and disassemble the frame and connecting rods, separating the frame and connecting rods for easy operation of the cage box on the frame. The dovetail blocks and dovetail grooves can be used to easily assemble and disassemble the cage box and connecting rods, allowing for individual operation of the cage box, further improving convenience.

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses a laboratory mouse cage rack with high space utilization. (Refer to...) Figure 1 It includes a base 1, a support rod 11, a connecting block 12 and a connecting rod 13. The support rod 11 is rotatably mounted on the base 1 via a bearing. The length of the support rod 11 is set in the vertical direction. A counterweight is fixedly mounted on the base 1 to maintain the balance of the entire rat cage frame. Several movable wheels 3 are rotatably mounted on the lower surface of the base 1 to facilitate the movement of the rat cage frame.

[0026] Reference Figure 1 and Figure 2 The connecting block 12 is integrally mounted on the top of the support rod 11. Several connecting rods 13 are provided on the side wall of the connecting block 12. In this embodiment, four connecting rods 13 are symmetrically arranged. The length direction of the connecting rods 13 is horizontal, and the length directions of adjacent connecting rods 13 are perpendicular to each other. A frame 2 is provided on the side wall of the connecting rod 13. The frame 2 is arranged along the length direction of the connecting rod 13. Several cage boxes 21 are provided on the frame 2. In this embodiment, three cage boxes 21 are provided on each frame 2. The side walls of the cage boxes 21 are made of transparent material, and the top of the cage boxes 21 can be opened and closed to take out and put in experimental animals. By placing the cage boxes 21 at a high position, other experimental supplies can be placed on the base 1, which effectively improves the space utilization rate and reduces the space occupied by the mouse cage rack. During the experiment, the staff can rotate the support rod 11 to operate and observe the cage boxes 21 in different positions, so as to facilitate the operation of the mouse cage rack.

[0027] Reference Figure 1 and Figure 2The support rod 11 has an air inlet groove 4 along its length. A fan 5 and a purifier 51 are bolted to the outer wall of the support rod 11. An air inlet hole 41 communicating with the air inlet groove 4 is opened on the side wall of the support rod 11. The purifier 51 is connected between the air inlet hole 41 and the fan 5. An air inlet chamber 42 is provided in the connecting block 12, which is connected to the air inlet groove 4. A guide block 6 is provided in the air inlet chamber 42 and on its top wall. An air outlet groove 43 communicating with the air inlet chamber 42 is provided in the connecting rod 13. Several air outlet holes 44 communicating with the air outlet groove 43 are opened on the surface of the connecting rod 13. The number of air outlet holes 44 corresponds to the number of cage boxes 21. The cage box 21 is fitted to the side wall of the connecting rod 13. The side wall of the cage box 21 is provided with ventilation holes 211 corresponding to and communicating with the air outlet holes 44. Several ventilation holes 212 penetrate the cage box 21. External air is drawn into the air inlet slot 4 through the air inlet hole 41 by the fan 5. The air then flows from the air inlet slot 4 into the air inlet chamber 42 in the connecting block 12, and is then diverted by the guide block 6 into the surrounding air outlet slots 43. Since the vent hole 211 and the air outlet hole 44 are aligned with each other, the airflow in the air outlet slot 43 eventually enters the cage 21 through the vent hole 211. The gas in the cage 21 is discharged through the ventilation hole 212, thereby accelerating the airflow in the cage 21. The airflow helps maintain oxygen balance, prevents laboratory animals from suffocating or suffering physiological damage, helps stabilize the temperature and humidity in the cage 21, maintains the dynamic balance of gas exchange, avoids animal stress or microbial growth caused by high temperature and high humidity environment, improves sterilization efficiency, and protects animal health.

[0028] Reference Figure 1 and Figure 2 A set of mounting plates 7 are symmetrically fixed on the frame 2. Each mounting plate 7 has an integrally formed mounting block 71 at its end. The top of the connecting rod 13 has a mounting groove 72 for inserting and abutting the mounting block 71. The mounting groove 72 and the mounting block 71 are mutually compatible. By utilizing the cooperation between the mounting groove 72 and the mounting block 71, the frame 2 and the connecting rod 13 can be quickly assembled and disassembled, separating the frame 2 from the connecting rod 13 and facilitating operation of the cage 21 on the frame 2.

[0029] Reference Figure 1 The side wall of the cage 21 is fixedly provided with a dovetail block 8, and the top of the connecting rod 13 is provided with a dovetail groove 81 for inserting and engaging the dovetail block 8. By utilizing the cooperation between the dovetail block 8 and the dovetail groove 81, it is convenient to assemble and disassemble the cage 21 and the connecting rod 13, and the cage 21 can be operated independently, which further improves convenience.

[0030] Reference Figure 1A slide rail 9 is provided at the end of the connecting rod 13 away from the connecting block 12. The length direction of the slide rail 9 is perpendicular to the length direction of the connecting rod 13. An expansion box 91 is slidably mounted on the slide rail 9. The slide rail 9 and the connecting rod 13 are detachably connected by bolts. The expansion box 91, like the cage 21, can be used to cultivate experimental animals, maximizing space utilization. By utilizing the cooperation between the slide rail 9 and the expansion box 91, the position of the expansion box 91 can be changed, facilitating observation of different cages 21 and preventing the expansion box 91 from interfering with the cage 21.

[0031] The implementation principle of a high-space-utilization experimental mouse cage rack in this application embodiment is as follows: several frame bodies 2 are set on the side wall of the connecting block 12, and several cage boxes 21 are set on the frame bodies 2. The cage boxes 21 are set at a high position, so that other experimental supplies can be placed on the base 1, which effectively improves the space utilization rate and reduces the space occupied by the mouse cage rack. During the experiment, the staff can rotate the support rod 11 to operate the cage boxes 21 in different positions, so as to facilitate the operation of the mouse cage rack.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
