Description

Technical Field

[0001] This utility model relates to the field of laboratory animal equipment technology, and in particular to a rodent transport cage with adjustable tiers. Background Technology

[0002] Rodents, such as mice and rats, are the most widely used laboratory animals in life science research and drug experiments. During experiments, it is often necessary to transfer these animals from their breeding environment to the experimental site, or to transport them between different laboratories, which requires the use of specialized transport cages.

[0003] Currently, most rodent transport cages on the market are one-piece molded structures with fixed internal space. This design has revealed significant limitations in practical applications. For example, when transporting a single or small animal, using a standard-sized cage results in wasted space; and when transporting multiple animals simultaneously and isolating them to prevent cross-infection or mutual aggression, a large fixed space cannot meet the requirements for partitioning and isolation, forcing managers to prepare various sizes or quantities of cages to handle different transport tasks.

[0004] This reliance on cages of various sizes not only significantly increases the costs and burdens on research institutions in equipment procurement and warehousing management, but also makes transfer preparation work cumbersome. More importantly, the lack of an effective means to adjust the internal space in real time according to actual needs makes the existing transfer cages inflexible in the face of diverse and dynamic experimental requirements, and unable to achieve optimal utilization of cage space resources.

[0005] Therefore, this invention proposes an adjustable space rodent transport cage to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a rodent transfer cage with adjustable layers, which aims to improve the problems of fixed internal space and complicated and inconvenient fecal cleaning structure in the existing rodent transfer cage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a layered adjustable rodent transport cage, comprising: an outer shell, and a collection assembly detachably installed below the outer shell; the collection assembly includes a support frame and a perforated plate covering the support frame, and an adjustment assembly slidably disposed inside the outer shell, the adjustment assembly including a movable plate, a hollow column fixedly connected to the movable plate, a sliding column slidably housed inside the hollow column, a spring disposed inside the hollow column to push the sliding column, and a handle connected to the upper end of the sliding column; a positioning hole is provided on the inner wall of the outer shell, and the end of the sliding column of the adjustment assembly is pluggably engaged in the positioning hole by the elastic force of the spring.

[0008] Preferably, the bottom of the outer casing is provided with a sliding groove, and the top of the support frame of the collecting component is fixedly connected with a slider, which slides in cooperation with the sliding groove to realize the detachable installation between the collecting component and the outer casing.

[0009] Preferably, the support frame has a drawer that slides inside, and the drawer is located directly below the perforated plate.

[0010] Preferably, the spring is a compression spring, which is sleeved on the outer periphery of the sliding column, and the two ends of the spring abut against the inner bottom wall of the hollow column and the end of the sliding column that is connected to the handle, respectively.

[0011] Preferably, the handle is fixedly connected to the end of the sliding column that extends out of the hollow column.

[0012] Preferably, the movable plate of the adjustment component is a vertically arranged plate used to divide the internal space of the housing in the horizontal direction.

[0013] Preferably, the axial direction of the hollow column is perpendicular to the surface of the movable plate.

[0014] Preferably, a plurality of positioning holes are provided at equal intervals on the inner wall of the outer casing along the sliding direction of the moving plate.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problem that the internal space of existing transfer cages is fixed and cannot be flexibly adjusted according to the animal's size or feeding needs by setting a sliding movable plate with a spring-reset locking mechanism. It achieves the effect of quickly and conveniently changing the layout of the cage space, realizing multiple uses of one cage, and improving the applicability of the equipment.

[0016] 2. This utility model solves the problems of cumbersome feces cleaning, the need to move animals, and the easy pollution caused by the existing cages by setting a collection component with a perforated plate and a pull-out drawer at the bottom of the cage. It achieves effective separation of feces from the animal activity area, and the drawer can be pulled out directly during cleaning, which simplifies the operation and reduces disturbance to the animals.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-5 An embodiment of this utility model is provided: a rodent transfer cage with adjustable layers, including an outer shell 1 and a collection component 2 detachably installed below the outer shell 1. The outer shell 1 serves as the supporting frame of the entire device, and the collection component 2 is used to collect animal feces and separate them from the outer shell 1 for convenient cleaning. On the basic frame, an adjustment component 3 is also slidably arranged inside the outer shell 1 for dividing and adjusting the space inside the cage. Specifically, the adjusting component 3 includes a movable plate 301, which is a vertically arranged plate capable of sliding horizontally to separate the internal space of the outer casing 1. A hollow column 302 is fixedly connected to the movable plate 301, with its axis perpendicular to the surface of the movable plate 301. The hollow column 302 is a hollow cylindrical structure, and a sliding column 303 is slidably housed inside the hollow column 302. The sliding column 303 is a column that slides coaxially with the inner hole of the hollow column 302, and the end of the sliding column 303 extending out of the hollow column 302 is fixedly connected to... A handle 305 is attached, and a spring 304 is also provided inside the hollow column 302. The spring 304 is a compression spring and is sleeved on the outer periphery of the sliding column 303. The two ends of the spring 304 abut against the inner bottom wall of the hollow column 302 and the end of the sliding column 303 connected to the handle 305, respectively. In order to lock the moving plate 301, a plurality of positioning holes are equally spaced on the inner wall of the outer shell 1 along the sliding direction of the moving plate 301. The end of the sliding column 303 can be inserted and removed into any positioning hole under the elastic force of the spring 304.

[0021] To facilitate the collection and cleaning of feces, the collection component 2 separates the animal activity area from the feces collection area. The collection component 2 includes a support frame 201 as a frame, a perforated plate 205 covering the top of the support frame 201, and a drawer 203 slidingly housed inside the support frame 201. The drawer 203 is located directly below the perforated plate 205. To enable detachable installation between the collection component 2 and the outer shell 1, a groove 204 is provided at the bottom of the outer shell 1, and a slider 202 is fixedly connected to the top of the support frame 201. The slider 202 slides within the groove 204. The adjustment assembly 3 includes a movable plate 301, on which a hollow column 302 is fixedly connected perpendicularly to the plate surface. A sliding column 303 is slidably installed inside the hollow column 302. The sliding column 303 can reciprocate along the axial direction of the hollow column 302. A handle 305 is fixedly connected to the end of the sliding column 303 that extends out of the hollow column 302. Inside the hollow column 302, a compression spring 304 is sleeved on the outer periphery of the sliding column 303 to provide a restoring elastic force. One end of the spring 304 abuts against the inner bottom wall of the hollow column 302, and the other end abuts against the end of the sliding column 303 connected to the handle 305. The elastic force of the spring 304 always gives the sliding column 303 a tendency to extend out of the hollow column 302.

[0022] Meanwhile, a plurality of positioning holes are provided at equal intervals on the inner wall of the outer casing 1 on the sliding path of the movable plate 301. In the assembled state, the movable plate 301 is slidably disposed inside the outer casing 1, and the sliding column 303 of the adjusting component 3 is pushed by the spring 304, and its end can be plugged into and locked into one of the positioning holes, ensuring the fixed reliability of the movable plate 301 after the position is adjusted and preventing accidental sliding. To facilitate easy disassembly and installation between the collecting component 2 and the outer casing 1, a groove 204 is provided at the bottom of the outer casing 1. A slider 202 is fixedly connected to the top of the support frame 201 of the collecting component 2. The shape and size of the slider 202 are adapted to the groove 204. By sliding the slider 202 into the groove 204, the collecting component 2 is installed, and disassembly is achieved by reversing the operation. Inside the collecting component 2, the internal space of the support frame 201 is used to slide and receive the drawer 203, and the drawer 203 is located directly below the perforated plate 205. This ensures reliable self-locking and convenient adjustment of the component 3. The spring 304 is a compression spring, which is sleeved on the outer periphery of the sliding column 303. The two ends of the spring 304 abut against the inner bottom wall of the hollow column 302 and the end of the sliding column 303 connected to the handle 305, respectively. The handle 305 is fixedly connected to the end of the sliding column 303 that extends out of the hollow column 302. In order to achieve regular division of space, the moving plate 301 is a vertically arranged plate. The axial direction of the hollow column 302 is perpendicular to the plate surface of the moving plate 301. On the inner wall of the outer shell 1, a plurality of positioning holes are equally spaced along the sliding direction of the moving plate 301.

[0023] Working principle: When it is necessary to adjust the internal space of the outer shell 1, the operator pulls the handle 305 of the adjustment component 3 upward. The handle 305 will drive the sliding column 303 to slide inside the hollow column 302, and at the same time compress the spring 304. The end of the sliding column 303 will then disengage from the positioning hole on the inner wall of the outer shell 1. At this time, the moving plate 301 can slide horizontally to a new position inside the outer shell 1. When the moving plate 301 reaches the predetermined position, the handle 305 is released. The rebound force of the spring 304 will push the sliding column 303 to automatically reset, so that the end of the sliding column 303 is reinserted and locked into the new positioning hole, thereby reliably locking the moving plate 301 in the new position. In daily use, animal feces will pass through the perforated plate 205 and fall directly into the drawer 203 below, thus separating waste from the animal activity area. When cleaning is required, the drawer 203 can be directly pulled out from the support frame 201 for emptying and cleaning. When a thorough cleaning is required, the operator can hold the entire collection component 2 and let the slider 202 slide out along the groove 204 at the bottom of the outer shell 1, thereby completely separating the collection component 2 from the outer shell 1.
