Description

Technical Field

[0001] This invention relates to the field of laboratory animal husbandry equipment technology, and more specifically to a modular, independently ventilated cage system frame that is easy to assemble and disassemble. Background Technology

[0002] Throughout the development of human life sciences, laboratory animals have always been an important component of life science research. Currently, the mainstream equipment for raising mice and rats in the industry is the Independent Ventilated Cage System (IVC system). The IVC system can effectively protect the safety of operators, animals, and the environment, and is widely used in the husbandry and management of laboratory animals.

[0003] Traditional IVC systems mainly consist of three parts: the IVC unit, cage racks, and cage boxes. The cage racks are equipped with cage box air supply and exhaust duct systems. In a barrier environment, air is filtered by the IVC unit's high-efficiency filters and then delivered to each individual cage box through the cage rack's air supply ducts. After the airflow circulates within the cage, the exhaust gas in the cage box passes through the cage box and cage rack's exhaust ducts, and is then filtered by the main unit's exhaust before being discharged. This unidirectional airflow design ensures that the air inside the cage remains clean, thus providing a suitable rearing environment for SPF (specific pathogen-free) mice and rats. However, existing IVC cage rack technology has the following main problems:

[0004] Traditional cages are bulky, especially in terms of cleaning and disinfection. Their large size presents numerous challenges for cleaning. Because the cages are not disassembled, cleaning can only be done on the entire cage simultaneously. This not only requires a significant amount of cleaning space but also increases the demands on cleaning equipment and facilities. For example, dedicated walk-in cage washer machines or large cleaning areas are essential, but the investment costs for such equipment and facilities are high, and they occupy a large area, further burdening the construction and operation of laboratories.

[0005] Therefore, how to provide a cage frame with a modular design that is easy to assemble and disassemble, in order to solve the difficulties of cleaning and disinfection, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] Therefore, the present invention provides a modular, independent ventilated cage system frame that is easy to assemble and disassemble, which can solve the aforementioned problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A modular, independently ventilated cage system frame that is easy to assemble and disassemble includes a frame base. Multiple shelf bodies are arranged in a matrix on the frame base. These shelf bodies are horizontally inserted and sequentially inserted vertically via uprights. Each shelf body has a vertically arranged air inlet and exhaust channel on its inner side, and its outer wall is fixed with an air inlet nozzle and an exhaust nozzle that respectively communicate with the air inlet and exhaust channels. A cage box bracket can be detachably connected to the outer wall of each shelf body.

[0009] Through the above technical solution, the present invention provides a modular, independently ventilated cage system frame that is easy to assemble and disassemble. Modular assembly is achieved through the horizontal and vertical interlocking of the main body of the shelf. The modular structure allows the cage frame to be disassembled, solving the problem of difficult cleaning and disinfection of traditional cage frames, reducing the requirements for cleaning equipment and space. The matrix-arranged main body of the shelf can adjust the number and layout of cages as needed, improving space utilization. The design of the air intake and exhaust channels ensures that each cage can obtain independent ventilation, providing a good living environment for laboratory animals. The modular design of the present invention facilitates assembly and disassembly.

[0010] Preferably, in the aforementioned modular independent ventilation cage system frame that is easy to assemble and disassemble, a slot is provided on the side wall of the shelf body. The cage box bracket includes a vertical plate that inserts into the slot and a support plate perpendicular to the vertical plate. A cage box is detachably connected to the support plate. The cage box has an air inlet and an air outlet that correspond to and communicate with the air inlet and air outlet, respectively. The insertion design of the slot and the vertical plate makes the connection between the cage box bracket and the shelf body more stable, improving the structural strength of the entire cage frame. The detachable connection between the cage box and the cage box bracket, as well as the corresponding communication between the air inlet and air outlet and the air outlet, facilitates the quick installation and disassembly of the cage box, improving work efficiency. At the same time, the high precision of the fit between the various structures ensures more reliable sealing.

[0011] Preferably, in the aforementioned modular independent ventilation cage system frame that facilitates assembly and disassembly, a limiting groove is formed on the top surface of the support plate along its length, and a radially protruding slide bar is provided on the side wall of the cage box. The slide bar can slide within the limiting groove, and its two ends have protrusions that engage with the corresponding slots at both ends of the limiting groove. The cooperation between the limiting groove and the slide bar, as well as the engagement of the protrusions with the slots, ensures accurate positioning and reliable fixation of the cage box on the support plate, preventing displacement of the cage box during use. The sliding design of the slide bar makes the installation and disassembly of the cage box more convenient; the operation can be completed simply by sliding the slide bar into the limiting groove and engaging the protrusions, improving the ease of operation.

[0012] Preferably, in the aforementioned modular independent ventilation cage system frame that facilitates assembly and disassembly, a positioning indicator rod is rotatably connected to the inner side of the support plate and the end furthest from the vertical plate. One end of the positioning indicator rod has an upwardly extending protrusion, and the other end is an indicator surface. The top surface of the support plate has a clearance hole corresponding to the protrusion. The positioning indicator rod is designed to visually indicate whether the cage box is correctly installed. When the cage box is not installed, the indicator surface is exposed, alerting the operator; when the cage box is installed, the indicator surface is hidden, allowing the operator to quickly determine the installation status. This visual cue reduces the time and effort required for operators to check the cage box installation status, improving the assembly and usage efficiency of the entire cage frame.

[0013] Preferably, in the aforementioned modular independent ventilation cage system frame that is easy to assemble and disassemble, the opposing side walls of two adjacent shelf bodies have interlocking parts. The design of the interlocking parts allows for a tight connection between adjacent shelf bodies, enhancing the structural stability of the entire cage frame and preventing the shelf bodies from loosening or shifting during use. The fit of the interlocking parts ensures precise alignment of the shelf bodies during assembly, improving assembly quality.

[0014] Preferably, in the aforementioned modular, independently ventilated cage system frame that is easy to assemble and disassemble, the interior of the shelf body has a through-rod channel. The bottom end of the upright passes through the through-rod channel inside the bottom shelf body and is fixedly connected to the frame base; the top end of the upright passes through the through-rod channel inside the top shelf body and is fixed with a top plate parallel to the frame base. The upright is connected to the shelf body through the through-rod channel and fixed to the frame base and top plate, forming a stable vertical support structure, ensuring the overall stability of the cage frame. The through-rod channel design makes the installation and disassembly of the upright more convenient, further improving the modularity and assembly efficiency of the cage frame.

[0015] Preferably, in the aforementioned modular independent ventilation cage system frame that is easy to assemble and disassemble, an air inlet pipe communicating with the air inlet channel and an exhaust pipe communicating with the exhaust channel are installed on the top plate. The air inlet and exhaust pipes on the top plate enable centralized ventilation management of the entire cage frame, facilitating the maintenance and control of the ventilation system. The centralized layout of the air inlet and exhaust pipes ensures uniform air distribution within the cage frame, further optimizing the ventilation effect of the cage.

[0016] Preferably, in the aforementioned modular independent ventilation cage system frame that is easy to assemble and disassemble, silicone sleeves are installed between two adjacent air intake channels and between two adjacent exhaust channels in the vertical direction. The installation of silicone sleeves can effectively prevent air leakage between the air intake and exhaust channels, improving the sealing performance of the ventilation system; the silicone sleeves have a certain degree of elasticity, which can play a role in buffering and shock absorption to a certain extent, reducing vibration and noise generated during airflow.

[0017] Preferably, in the aforementioned modular independent ventilation cage system frame that is easy to assemble and disassemble, silicone plugs are installed at the bottom of both the bottom air intake channel and the bottom exhaust channel. The silicone plugs effectively seal the bottom of the bottom air intake channel and exhaust channel, preventing air leakage from the bottom and ensuring the normal operation of the ventilation system. The silicone plugs are also easy to install and replace, facilitating the maintenance and upkeep of the ventilation system.

[0018] Preferably, in the aforementioned modular independent ventilated cage system frame that is easy to assemble and disassemble, the frame base is equipped with casters, and anti-collision wheels are installed at its four corners. The casters allow the cage frame to be easily moved to the required position, improving the flexibility and ease of use of the cage frame; the anti-collision wheels can effectively prevent the cage frame from colliding with surrounding equipment or personnel during movement, protecting the safety of equipment and personnel.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a modular independent ventilation cage system frame that is easy to assemble and disassemble, and has the following beneficial effects:

[0020] 1. This invention adopts a modular structure, where the main shelf, cage brackets, uprights, and other components can be independently disassembled and assembled. This design allows the cage rack to be quickly disassembled into individual parts during cleaning and disinfection, solving the problems of traditional cage racks being bulky and difficult to clean. The modular assembly and disassembly method simplifies the operation process, reduces the time and labor costs required for cleaning and maintenance, and improves the operational efficiency of the laboratory.

[0021] 2. The modular structure of this invention eliminates the need for a large disinfection transfer chamber. It can thoroughly disinfect each shelf body and its components using the existing cage disinfection transfer chamber (pulsating vacuum sterilizer). This solves the technical problem in the prior art where cages are bulky and some old or small animal houses do not have a large transfer chamber, resulting in incomplete disinfection.

[0022] 3. Each shelf in this invention is designed with an independent air intake channel and an exhaust channel, which are connected to the cage via air intake nozzles and exhaust nozzles. This ensures that each cage can obtain independent and stable ventilation, avoids cross-contamination of air, and provides a cleaner breeding environment for experimental animals. Silicone sleeves are installed between adjacent channels, and silicone plugs are installed at the bottom of the lowest channel to effectively prevent air leakage, improve the sealing and reliability of the ventilation system, and further optimize the ventilation effect.

[0023] 4. The main body of the shelf in this invention is arranged in a matrix, and the number and layout of cages can be flexibly adjusted according to experimental needs to maximize the use of limited laboratory space. The cage brackets on adjacent shelf bodies cooperate with each other to support the cages, further improving space utilization while ensuring stable support of the cages.

[0024] 5. The cage bracket of this invention is designed with a positioning indicator rod, which intuitively displays the installation status of the cage and avoids structural instability or poor ventilation caused by the cage not being installed in place. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] See appendix Figure 1-13This invention discloses a modular, independently ventilated cage system frame that is easy to assemble and disassemble. It includes a frame base 1, on which multiple shelf bodies 2 are arranged in a matrix. The multiple shelf bodies 2 are inserted horizontally and arranged in sequence vertically by uprights 3. Each shelf body 2 has a vertically arranged air inlet channel 21 and an exhaust channel 22 on its inner side, and its outer side wall is fixed with an air inlet nozzle 23 and an exhaust nozzle 24 that are respectively connected to the air inlet channel 21 and the exhaust channel 22. A cage box bracket 4 can be detachably connected to the outer side wall of each shelf body 2.

[0043] To further optimize the above technical solutions, such as Figure 2 As shown, a slot 25 is provided on the side wall of the shelf body 2. The cage bracket 4 includes a vertical plate 41 that is inserted into the slot 25, and a support plate 42 that is arranged perpendicularly to the vertical plate 41. A cage 5 is detachably connected to the support plate 42. The cage 5 has an air inlet 51 and an air outlet 52 that are correspondingly connected to the air inlet nozzle 23 and the air outlet nozzle 24.

[0044] To further optimize the above technical solution, the insertion and mating structure of the slot 25 and the vertical plate 41 is as follows: Figure 2 , 4 As shown in Figures 8-9, other types of interlocking structures are also possible. The slot 25 protrudes radially toward the shelf body 2, and the bottom of the vertical plate 41 has a buckle 411 that engages with the bottom wall of the slot 25 to improve interlocking stability.

[0045] To further optimize the above technical solutions, such as Figure 3-4 As shown, a limiting groove 421 is formed on the top surface of the bearing plate 42 along its length direction, and a radially protruding slide 53 is provided on the side wall of the cage box 5. The slide 53 can be slidably placed in the limiting groove 421, and its two ends have protrusions 531 that correspond to and engage with the slots 4211 at both ends of the limiting groove 421.

[0046] To further optimize the above technical solution, the air inlet nozzle 23 and the air outlet nozzle 24 are made of soft silicone corrugated sleeves with a certain degree of elasticity. When the cage box 5 is in place, it exerts a certain amount of pressure on the air inlet nozzle 23 and the air outlet nozzle 24, causing the cage box 5 to move towards the shelf body 2, so that the two end slots 4211 of the limiting groove 421 are engaged, thus achieving precise placement of the cage box 5.

[0047] To further optimize the above technical solutions, such as Figure 4-7 As shown, a positioning indicator rod 6 is rotatably connected to the inner side of the bearing plate 42 and the end away from the vertical plate 41. One end of the positioning indicator rod 6 has an upwardly extending protrusion 61, and the other end is an indicator surface 62. The top surface of the bearing plate 42 is provided with a clearance hole 422 corresponding to the protrusion 61.

[0048] To further optimize the above technical solutions, such as Figure 7 As shown, the positioning indicator 6 adopts a lever design. When the cage 5 is not placed in the cage bracket 4, the indicator surface 62 of the positioning indicator 6 falls down under its own weight and is exposed to the bottom of the cage bracket 4. The indicator surface 62 is marked with a conspicuous color (such as red). When the cage 5 is placed in the cage bracket 4, the cage 5 presses against the end of the positioning indicator 6 with the protrusion 61, and then the end of the indicator surface 62 enters the cage bracket 4.

[0049] To further optimize the above technical solution, the side walls of two adjacent shelf bodies 2 have interlocking parts.

[0050] To further optimize the above technical solutions, such as Figure 9 As shown, in this embodiment, five shelf bodies 2 are interlocked in the horizontal direction. The opposite side walls of two adjacent shelf bodies 2 have interlocking protrusions 29 and interlocking grooves 291 that are connected to the protrusions 29.

[0051] To further optimize the above technical solution, in this embodiment, taking five shelf bodies 2 as an example, the leftmost shelf body 2 is provided with two slots 25, which are used to insert two cage box brackets 4 respectively; the other four shelf bodies 2 are each provided with one slot 25, which is used to insert one cage box bracket 4 respectively; each cage box 5 is supported by two adjacent cage box brackets 4. Specifically, the two cage box brackets 4 on the leftmost shelf body 2 are used to support one cage box 5; the right cage box bracket 4 of the leftmost shelf body 2 is adjacent to the cage box bracket 4 on the second shelf body 2, and the two cooperate to support one cage box 5; similarly, the cage box bracket 4 on the second shelf body 2 cooperates with the cage box bracket 4 on the third shelf body 2 to support another cage box 5, and so on; through this design, the cage box brackets 4 on adjacent shelf bodies 2 cooperate with each other to achieve continuous support and stable support of the cage box 5.

[0052] At the same time, such as Figure 3-5 As shown, a partition baffle 43 is fixed on the support plate 42 and arranged perpendicularly thereto. The partition baffle 43 divides the support plate 42 into a first support surface 423 and a second support surface 424. A limiting groove 421 is provided on both the first support surface 423 and the second support surface 424 for cooperating with the sliding strip 53 on the side wall of the cage box 5. Through the setting of the partition baffle 43 and the limiting groove 421, each cage box bracket 4 can stably support two cage boxes 5. At the same time, through the cooperation of the cage box brackets 4 on the adjacent shelf bodies 2, the continuous support and stable layout of the cage boxes 5 are realized, thereby improving the space utilization rate.

[0053] To further optimize the above technical solution, each shelf body 2 has a rod channel 26 inside. The bottom end of the upright 3 passes through the rod channel 26 inside the bottom shelf body 2 and is fixedly connected to the frame base 1. The top end of the upright 3 passes through the rod channel 26 inside the top shelf body 2 and is fixed with a top plate 7 parallel to the frame base 1.

[0054] Meanwhile, the structural layout of the rod passage 26 inside the shelf body 2 is consistent with the layout of the slot 25.

[0055] It should be noted that the layout of slot 25, rod channel 26, and cage bracket 4 is not limited to the structural layout in this embodiment, and can be adjusted according to the actual situation.

[0056] To further optimize the above technical solution, the top end of the pole 3 is threaded and extends above the top plate 7, and is locked to the top surface of the top plate 7 by bolts.

[0057] To further optimize the above technical solution, an intake pipe 71 connected to the intake channel 21 and an exhaust pipe 72 connected to the exhaust channel 22 are installed on the top plate 7.

[0058] To further optimize the above technical solution, silicone sleeves 27 are installed between two adjacent intake channels 21 and between two adjacent exhaust channels 22 in the vertical direction.

[0059] To further optimize the above technical solution, the top of both the air intake channel 21 and the exhaust channel 22 has a mounting surface extending to the top of the shelf body. The silicone sleeve 27 is fitted on the mounting surface and extends to the bottom of the air intake channel 21 and the exhaust channel 22 of the upper shelf body 2.

[0060] To further optimize the above technical solution, silicone plugs 28 are installed at the bottom of the bottom air intake channel 21 and the exhaust channel 22.

[0061] To further optimize the above technical solution, four casters 11 are installed at the bottom of the frame base 1, and anti-collision wheels 12 are installed at its four corners.

[0062] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
