Description

Technical Field

[0001] This application relates to the field of animal husbandry, and in particular to a modular laboratory dog ​​housing cage and a method for assembling the same. Background Technology

[0002] In the field of laboratory animal husbandry, laboratory dogs are important experimental subjects, and the rationality and scientific nature of their housing environment have a crucial impact on the accuracy and reliability of experimental results. A well-designed cage not only provides laboratory dogs with a comfortable living space and reduces their stress response, but also facilitates operation and management by researchers, improving experimental efficiency.

[0003] In related technologies, laboratory dogs are typically housed in individual cages, meaning each dog is provided with a cage tailored to its physiological needs, equipped with a food and water bowl. Operators must provide food and water regularly and in measured amounts, and periodically clean up excrement from the cages. This one-dog-one-cage system effectively reduces the risk of disease transmission.

[0004] Regarding the aforementioned technologies, the inventors believe that although the above-mentioned feeding methods can meet the physiological needs of experimental dogs, due to poor spatial flexibility and lack of environmental enrichment, experimental dogs are prone to developing stereotyped behaviors when kept in the same environment for a long time, which is detrimental to their mental health. Summary of the Invention

[0005] To improve the spatial flexibility and environmental enrichment of breeding cages, this application provides a modular experimental dog breeding cage and a method for assembling it.

[0006] Firstly, this application provides a modular experimental dog breeding cage, which adopts the following technical solution: A modular laboratory dog ​​cage includes at least one cage unit, a feeding device arranged on the outside of the cage unit, an automatic drinking device installed on the cage unit, and a waste disposal device arranged at the bottom of the cage unit. The cage unit includes an outer frame and a caster wheel assembly arranged at the bottom of the outer frame. The outer frame includes a first side plate and a second side plate arranged opposite each other, and two third side plates connecting the two sides of the first side plate and the two sides of the second side plate. The first side plate has a rotatably mounted main door and is provided with a first locking assembly for locking the main door. The third side plates have a slidingly arranged movable door on the side closest to the first side plate. The cage unit is equipped with a mounting rail for horizontal sliding of the movable door, and the first side plate is equipped with a second locking component for locking the movable door. The cage unit also includes a shelf structure for the experimental dog to move around in. The shelf structure includes a first shelf horizontally arranged at the bottom of the outer frame, a second shelf horizontally arranged in the middle of the outer frame, and a ladder connecting the first shelf and the second shelf. The third side plate has a rotatably arranged secondary door on the outside of the second shelf. The third side plate is equipped with a third locking component for locking the secondary door when it is closed, and the second side plate is equipped with a fourth locking component for locking the secondary door when it is open.

[0007] By adopting the above technical solutions, operators and experimental dogs can enter and exit the cage unit through the main door. The feeding device and automatic drinking device can meet the feeding needs of the experimental dogs. The sewage discharge device can discharge sewage from the cage unit to ensure a clean environment inside the cage. The shelf structure set in the cage unit can effectively expand the activity space of the experimental dogs in the cage unit. Operators can move individual cage units through the universal wheel assembly, and use the movable door and secondary door configuration to realize the combination and isolation operation between adjacent cage units. The movable door can realize the isolation and connection of the first-level space, and the secondary door can realize the isolation and connection of the second-level space. The modular construction improves the spatial flexibility and environmental enrichment of the experimental dog breeding cage.

[0008] Optionally, the first locking assembly includes a first locking post disposed at the movable end of the main door, a first locking plate slidably disposed on the first side plate, and a first locking hook disposed on the first locking plate for locking by the first locking post; the number of the first locking posts is two and they are symmetrically arranged at the movable end of the main door, and the first locking plate has two first locking hooks corresponding one-to-one with the two first locking posts; the first side plate is provided with a first positioning post, and the first locking plate has a first sliding hole along its length for sliding arrangement of the first positioning post; the number of the first positioning posts is two and they are spaced apart on the first side plate, and the first locking plate has two first sliding holes corresponding one-to-one with the two first positioning posts.

[0009] By adopting the above technical solution, when the operator needs to enter the feeding cage or release the experimental dog from the feeding cage, the first locking plate is slid upward so that the two first locking hooks separate from the corresponding first locking pins, thereby unlocking the main door; when the main door needs to be locked, the first locking plate is slid upward again and the main door is closed, and the first locking plate is released so that the two locking hooks engage with the corresponding first locking pins, thereby relocking the main door; by using the cooperation between the first positioning pin and the first sliding hole on the first locking plate, the sliding of the first locking plate is made more stable, ensuring the smoothness of the main door locking and unlocking operation.

[0010] Optionally, the second locking assembly includes a second positioning post disposed on the first side plate, a second guide post disposed on the first side plate, and a second locking plate rotatably mounted on the second positioning post. The second locking plate has a second positioning hole for arranging the second positioning post and a second arc-shaped hole for arranging the second guide post. The center of the arc of the second arc-shaped hole coincides with the projection of the axis of the second positioning post onto the second locking plate.

[0011] By adopting the above technical solution, when the movable door is installed on the third side panel, the inner side of the second locking plate abuts against the outer frame of the movable door to restrict the movable door from being pulled outward. When it is necessary to remove the movable door on the third side panel, the operator rotates the second locking plate towards the direction closer to the first side panel, and the second locking plate separates from the movable door to unlock the movable door, so that the movable door can be pulled out along the length of the mounting groove. The specific structure of the second locking component realizes the locking and unlocking of the movable door, which facilitates the connection operation of adjacent cage units when needed in the modular experimental dog breeding cage.

[0012] Optionally, the third locking component includes a locking pin, and the secondary door has a locking hole for the movable rod of the locking pin to extend into; the fourth locking component includes a locking plate that is vertically slidably arranged on the third side plate, and the locking plate has a locking groove for limiting the movable end of the secondary door; the second side plate has multiple vertically arranged guide rods, and the locking plate has multiple guide holes that correspond one-to-one with the multiple guide rods.

[0013] By adopting the above technical solution, the locking pin and the locking hole on the secondary door can be aligned and effectively locked when the secondary door is closed. The locking plate and locking slot can limit the opening of the secondary door and the second side plate, and the cooperation of the guide rod and guide hole ensures the stability of the vertical sliding of the locking plate, thereby realizing the locking operation when the secondary door is opened or closed, which helps to improve the convenience and safety of the use of the breeding cage.

[0014] Optionally, the sewage discharge device includes a sewage discharge plate inclinedly arranged at the bottom of the cage unit; the sewage discharge plate is arranged at the bottom of the first layer plate and inclined downward in a direction away from the first side plate, and the sewage discharge plate has an extension on one side of the first side plate that extends in a direction away from the second side plate.

[0015] By adopting the above technical solution, the inclined sewage discharge plate can receive the sewage from the cage unit and discharge it smoothly into the ditch along the inclined direction. The extension can expand the receiving range of the sewage discharge plate, reduce the leakage of sewage from the breeding cage, and help keep the breeding cage clean.

[0016] Optionally, the automatic drinking device includes a water outlet pipe arranged on the first side plate, a drinking pipe connected to the water outlet pipe and extending into the inner side of the outer frame, a drinking component arranged at the output end of the drinking pipe, and a detection pipe connected to the water outlet pipe and extending towards the extension portion; the first side plate has an installation through hole for arranging the drinking pipe, and the first layer plate has a plurality of first drainage holes on the side near the drinking pipe; the drinking component includes a housing, a drinking head horizontally slidably arranged inside the housing, and a reset spring for driving the drinking head to reset, the drinking head having a drinking chamber and a drinking outlet on the side away from the reset spring; the housing has an outlet connected to the drinking pipe, and the drinking head has an inlet connected to the drinking chamber and corresponding to the outlet; the input end of the detection pipe is provided with a control valve.

[0017] By adopting the above technical solution, the drinking component can automatically reset after the experimental dogs drink, realizing the automatic water supply function, which makes it convenient for the experimental dogs to drink water at any time. Water splashed during drinking can be discharged to the drain plate in time through the first drain hole, reducing the accumulation of water on the first layer plate. The detection tube is equipped with a control valve to control its opening and closing, which allows the operator to detect the water supply and drinking water quality from the outside of the breeding cage. The drinking water flowing out of the output end of the detection tube can be smoothly discharged through the extension of the drain plate, ensuring drinking water hygiene while effectively reducing the risk of stress to the experimental dogs due to direct contact.

[0018] Optionally, the main door has a first arrangement opening and a second arrangement opening spaced apart horizontally; the feeding device includes a food box detachably installed at the first arrangement opening; the food box includes a first box body, a first baffle arranged obliquely on the first box body, and a first limiting member arranged on the first box body; the first box body has a first feeding opening on the side facing the main door, which is directly opposite the first arrangement opening; the top of the first box body has a first observation opening and the first baffle is provided at the first observation opening, and the first baffle has an observation elongated hole along the oblique direction; the bottom of the first box body has multiple drainage holes; the first box body has first flanges on both sides of the first feeding opening, and the main door has two first sliding grooves on both sides of the first arrangement opening that correspond one-to-one with the two first flanges; the main door has a first limiting part for the first limiting member to abut against.

[0019] By adopting the above technical solution, the food box can be detached and installed by the cooperation of the first flange and the first sliding groove, and is locked and limited with the main door by the first limiting component, which reduces the risk of the food box shaking during the experimental dogs' eating process and facilitates the replacement and cleaning of the food box; the operator can check the experimental dogs' eating situation through the observation hole on the first baffle, and add food through the first observation port on the top of the food box, reducing the risk of stress caused by direct contact with the experimental dogs; the drainage hole at the bottom of the food box can drain the water accumulated in the food box and keep the food dry.

[0020] Optionally, the feeding device further includes a water box detachably installed at the second arrangement opening; the water box includes a second box body, a second baffle inclinedly arranged in the second box body, and a second limiting member arranged in the second box body; the second box body has a second feeding opening on the side facing the main door, which is directly opposite the second arrangement opening; the top of the second box body has a second observation opening and a second baffle is provided at the second observation opening; the second box body has second flanges on both sides of the second feeding opening; the main door has two second sliding grooves on both sides of the second arrangement pocket, which correspond one-to-one with the two second flanges; the main door has a second limiting part for the second limiting member to abut against.

[0021] By adopting the above technical solution, when experimental dogs need to ingest drinking water or liquid medicine under special circumstances, operators can feed the experimental dogs through the water box; the water box can be detached and installed by the second flange and the second slide groove, and is locked to the main door by the second limiting component, reducing the risk of the water box shaking during the experimental dog's drinking process, and facilitating the replacement and cleaning of the water box; the operator can check the experimental dog's drinking situation through the first observation port on the top of the water box, reducing the risk of stress caused by direct contact with the experimental dog.

[0022] Optionally, the feeding device further includes a cover plate detachably installed on the second arrangement opening; the cover plate includes a cover side plate for covering the second arrangement opening, a third flange connected to the top side of the cover side plate and extending away from the second arrangement opening, and a third limiting member arranged on the cover side plate; the cover side plate has symmetrically arranged sliding portions on both sides, and the main door is provided with two third sliding grooves on both sides of the second arrangement opening that correspond one-to-one with the two sliding portions; the main door has a third limiting portion for the third limiting member to abut against.

[0023] By adopting the above technical solution, under normal circumstances where a water box is not needed, the operator can use a cover plate to cover the second arrangement port. The cover plate slides and engages with the third sliding groove of the main door through the sliding parts on both sides, and is abutted and limited by the third limiting member with the third limiting part of the main door, thus realizing the detachable installation of the second arrangement port; the third flange makes it easy for the operator to pull out the cover plate, thereby facilitating the adjustment of the usage status of the second arrangement port as needed.

[0024] Secondly, this application provides a method for assembling a modular experimental dog breeding cage, employing the following technical solution: A method for assembling a modular laboratory dog ​​cage, using the aforementioned modular laboratory dog ​​cage, includes the following steps: S1. Arrange at least two cage units side by side, with the first side plates of each cage unit located on the same plane; S2. Unlock the second locking components corresponding to the two adjacent third side panels, so that the movable door can be removed along the mounting rail towards the first side panel; S3. Unlock the third locking components on the two adjacent third side panels, open the secondary door, and lock it through the fourth locking component.

[0025] By adopting the above technical solution, multiple cage units can be combined by arranging them side by side, removing the movable door, and opening the secondary door. Multiple cage units can be combined into a larger breeding area, which facilitates the free movement of experimental dogs between different cage units and improves the activity range and comfort of the experimental dogs.

[0026] In summary, this application includes at least one of the following beneficial technical effects: A modular laboratory dog ​​cage includes a cage unit, a feeding device, an automatic drinking device, and a waste disposal device. The feeding device and automatic drinking device meet the feeding needs of the laboratory dogs, while the waste disposal device drains wastewater from the cage unit to ensure a clean environment. A shelf structure within the cage unit effectively expands the activity space for the laboratory dogs. Operators can move individual cage units using casters and utilize movable doors and secondary doors to achieve combination and isolation between adjacent cage units. The movable doors allow for isolation and connection between one level of space, while the secondary doors allow for isolation and connection between two levels of space. Modular construction improves the spatial flexibility and environmental richness of the laboratory dog ​​cage. The drinking water assembly automatically resets after the experimental dogs drink, realizing an automatic water supply function, making it convenient for the experimental dogs to drink water at any time. Water splashed during drinking can be discharged to the drain plate in time through the first drain hole, reducing the accumulation of water on the first layer of the plate. The detection tube is equipped with a control valve to control its opening and closing, allowing operators to detect the water supply and drinking water quality from the outside of the feeding cage. The drinking water flowing out of the output end of the detection tube can be smoothly discharged through the extension of the drain plate, ensuring drinking water hygiene while effectively reducing the risk of stress to the experimental dogs due to direct contact. A method for assembling a modular laboratory dog ​​cage allows for the combination of multiple cage units through side-by-side arrangement, removal of the movable door, and opening of the secondary door. This combination of multiple cage units creates a larger feeding area, facilitating free movement of laboratory dogs between different cage units and improving their activity range and comfort.
