Description

Technical Field

[0001] This utility model relates to the field of laboratory animal husbandry equipment, and in particular to a rat cage that is easy to operate in experiments. Background Technology

[0002] Rats are commonly used laboratory animals in scientific research. Currently, existing rat cages present several problems. First, in terms of housing, multiple rats are typically kept in the same cage. Due to rats' tendency to huddle together, finding a rat with a specific number is extremely inconvenient, often requiring a significant amount of time to search and identify, greatly reducing experimental efficiency. Second, most existing rat cage lids are one-piece structures, requiring the entire lid to be lifted when handling a rat. This allows rats to easily escape, increasing the workload for researchers and potentially interfering with the experiment. Third, regarding rat marking, the current common method is to apply dye to the rat's tail or fur for numbering. However, this method has significant drawbacks; the marks easily rub off over time, making it impossible to accurately identify the rat's number and affecting the accuracy and traceability of experimental data. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rat cage that is easy to operate in experiments, in order to address the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a rat cage that is easy to operate in experiments, characterized in that it includes: a cage body, a cage cover that is fastened and disposed on the top of the cage body, a plurality of isolation grooves that are spaced apart on the cage cover along the length direction, and an isolation plate that is inserted into the isolation grooves to divide the internal space of the cage body into a plurality of feeding chambers.

[0005] Each enclosure has an opening on its cage cover for catching mice. A switch baffle is rotatably connected to the opening. The outer surface of the switch baffle has a card groove, into which a card for marking the enclosure is inserted.

[0006] Preferably, the card groove has a T-shaped cross-section, including a lower groove and an upper groove. The width of the upper groove is smaller than that of the lower groove. The lower groove is used to insert a card, and the surface of the upper groove is hollowed out to allow the card to be viewed from above.

[0007] Preferably, the cage cover has a perforated structure, such as a grid structure, openings, or a mesh structure, to ensure the ventilation requirements inside the cage. Perforated structures can also be provided on the outer walls of the cage.

[0008] Preferably, the inner walls of the front and rear plates of the cage are provided with several slots in the vertical direction.

[0009] The isolation plate includes a limiting strip and a plate body connected below the limiting strip. After the plate body passes through the isolation groove, its front and rear ends are respectively inserted into the slots on the inner walls of the front and rear plates of the cage. The width of the limiting strip is greater than the isolation groove so that after the plate body is fully inserted into the slot, the limiting strip is still restricted above the isolation groove.

[0010] After the plate is fully inserted into the slot, the bottom of the plate comes into contact with the bottom of the cage.

[0011] The two side walls of the limiting strip are recessed inward to form several gripper grooves.

[0012] Preferably, at least two rollers are provided at vertical intervals at both the front and rear ends of the plate. The rollers are rotatably connected to the plate and can roll in contact with the inner wall of the slot when the plate is inserted into the slot.

[0013] Positioning marking areas are provided on the lower part of the outer walls at both the front and rear ends of the plate. Positioning observation windows are provided on the lower part of the front and rear plates of the cage. When the plate is fully inserted into the slot, the complete positioning marking area can be observed through the positioning observation windows.

[0014] Preferably, two arc-shaped spring pieces are symmetrically arranged on both sides of the inner wall below the slot. After the plate is fully inserted into the slot, the bottom roller passes exactly between the two arc-shaped spring pieces, and the positioning mark area on the plate completely reaches the area of ​​the positioning observation window.

[0015] Preferably, the rear end of the switch baffle is connected to the cage cover via a hinge, and the front end of the switch baffle is connected to the cage cover via a snap-fit ​​structure.

[0016] The cage cover and the cage body are connected by several snap-fit ​​structures.

[0017] Preferably, the snap-fit ​​structure includes a snap-fit ​​head and a snap-fit ​​base for snapping the snap-fit ​​head in place;

[0018] The card head includes a card strip body, a snap-fit ​​protrusion formed by bending the middle of the card strip body, an installation part formed by both ends of the card strip body, and a connecting part that transitions and connects the installation part and the snap-fit ​​protrusion; the middle of the snap-fit ​​protrusion protrudes outward to both sides to form an arc-shaped protrusion, and a card head cavity is formed in the middle.

[0019] The card holder includes a mounting plate, a mounting base disposed on the mounting plate, and two symmetrically arranged claws rotatably connected to the mounting base at the rear end; the two sides of the middle part of the claws are recessed inward to form elastic parts, and a clamping cavity is formed between the two claws to accommodate the locking protrusion.

[0020] The front end of the claw is rotatably connected to a pulley. When the two pulleys on the two claws are pressed by the locking protrusion, the two claws can open outward so that the locking protrusion enters the locking cavity.

[0021] Preferably, in the snap-fit ​​structure between the switch baffle and the cage cover, the snap head is disposed at the outer end of the switch baffle, and the snap seat is disposed at the corresponding position on the cage cover;

[0022] In the snap-fit ​​structure between the cage cover and the cage body, the snap head is located at the outer end of the cage cover, and the snap seat is located at the corresponding position on the cage body.

[0023] Preferably, the latching structure between the cage cover and the cage body is further provided with a safety mechanism on the latching seat. The safety mechanism includes a movable bolt movably connected to the mounting base, a connecting rod connected to the outer end of the movable bolt, a safety bolt connected to the other end of the connecting rod, an iron plate disposed at the inner end of the safety bolt, a first bolt hole opened on the mounting plate in the clamping cavity for the inner end of the safety bolt to be inserted, and a magnetic piece disposed at the bottom of the bolt hole for attracting the iron plate.

[0024] Preferably, the mounting base has a second bolt hole with a diameter larger than that of the movable bolt, and the inner end of the movable bolt is provided with a limiting ring with an outer diameter larger than that of the second bolt hole.

[0025] The beneficial effects of this utility model are:

[0026] 1. This utility model divides the rat cage into several relatively independent breeding rooms by setting an isolation groove on the cage cover and inserting an isolation plate, realizing the separate breeding of rats, avoiding the phenomenon of rats crowding together, making it easier and faster to find rats with specific numbers when conducting experiments, saving a lot of time and improving experimental efficiency.

[0027] 2. This utility model has an opening on the cage cover corresponding to each breeding room and a switch baffle. When catching mice, it is only necessary to open the switch baffle on the corresponding opening, without having to lift the entire cage cover. This effectively prevents mice from running out of the cage, reduces the difficulty of the experimenters' work, and ensures the smooth progress of the experiment.

[0028] 3. This utility model has a card groove on the switch baffle on the opening for inserting a card. The card can be marked with the mouse's number and can be replaced. This marking method is more durable and clearer than traditional dye marking, and the marking will not fall off. It is easy to accurately identify the mouse's number and improves the accuracy and traceability of experimental data.

[0029] 4. In some embodiments of this utility model, by setting rollers and positioning marking areas on the isolation plate and cooperating with setting arc-shaped spring pieces in the slot, it is convenient to determine whether the isolation plate is installed in place. Furthermore, the limiting effect of the arc-shaped spring pieces can prevent the plate from shaking up and down or moving upward due to the impact of rats in the breeding room, resulting in an excessively large gap between the plate and the bottom of the cage that allows rats to pass through.

[0030] 5. In some embodiments of this utility model, the design of the snap-fit ​​structure enables quick fixing and unlocking between the switch baffle and the cage cover, as well as between the cage cover and the cage body, facilitating operation.

[0031] 6. In some embodiments of this utility model, by setting a safety mechanism on the buckle structure between the cage cover and the cage body, even if there is some shaking or other external force during the handling and transfer of the rat cage, the buckle head is difficult to easily detach from the buckle seat, thereby ensuring a stable connection between the cage cover and the cage body.

[0055] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0056] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0057] Example 1

[0058] Reference Figures 1-4 A rat cage that is easy to operate in experiments includes: a cage body 1, a cage cover 2 that is fastened and set on the top of the cage body 1, a number of isolation slots 3 that are spaced apart along the length of the cage cover 2, and an isolation plate 4 that is inserted into the isolation slots 3 to divide the internal space of the cage body 1 into a number of feeding rooms 5.

[0059] Each cage cover 2 above the breeding chamber 5 has an opening 51 for catching mice inside the breeding chamber 5. A switch baffle 52 is rotatably connected to the opening 51. A card groove 53 is provided on the outer surface of the switch baffle 52. A card (not shown in the figure) for marking the breeding chamber 5 is inserted into the card groove 53.

[0060] The card groove 53 has a T-shaped cross-section, including a lower groove 531 and an upper groove 532. The width of the upper groove 532 is smaller than that of the lower groove 531. The lower groove 531 is used to insert cards, and the surface of the upper groove 532 is hollowed out to allow the cards to be viewed from above.

[0061] The shape and size of the lower slot 531 are adapted to the card, which is identified by a written number, and the card can be easily inserted and removed from the lower slot 531 for easy replacement.

[0062] The rear end of the switch baffle 52 is connected to the cage cover 2 via a hinge 54, and the front end of the switch baffle 52 is connected to the cage cover 2 via a snap-fit ​​structure 6. The cage cover 2 and the cage body 1 are connected by several snap-fit ​​structures 6. The switch baffle 52 can rotate around the cage cover 2 to open and close the opening 51. The size of the opening 51 is larger than that of the mouse, ensuring that the mouse can be put in and taken out of the feeding room 5.

[0063] The snap-fit ​​structure 6 can adopt a conventional structure. For the snap-fit ​​structure 6 on the switch baffle 52, it only needs to be able to fix the switch baffle 52 when it is closed. For the snap-fit ​​structure 6 between the cage cover 2 and the cage body 1, it only needs to be able to fix the cage cover 2 after it is fastened onto the cage body 1. In this embodiment, a snap-fit ​​structure 6 is provided on each of the four sides of the cage cover 2 and at the corresponding position on the cage body 1 to ensure the fixing effect of the cage cover 2.

[0064] The cage cover 2 has a perforated structure 21; in this embodiment, the perforated structure 21 is a grid structure to ensure the ventilation requirements inside the cage. The size of the perforated structure 21 must ensure that the mouse cannot squeeze out of it.

[0065] In this design, the inner walls of the front and rear panels of the cage 1 are provided with several slots 11 along the vertical direction. The isolation plate 4 includes a limiting strip 41 and a plate 42 connected below the limiting strip 41. After the plate 42 passes through the isolation groove 3, its front and rear ends are respectively inserted into the slots 11 on the inner walls of the front and rear panels of the cage 1. The width of the limiting strip 41 is greater than that of the isolation groove 3, so that even after the plate 42 is fully inserted into the slot 11, the limiting strip 41 is still restricted above the isolation groove 3, thus achieving the limiting function. It also facilitates the removal of the isolation plate 4 from the slot 11 through the limiting strip 41. In this embodiment, the two side walls of the limiting strip 41 are recessed inward to form several gripper grooves 411. By gripping the gripper grooves 411, it is easier to grasp the isolation plate 4 and remove it.

[0066] The shape and size of the slot 11 are adapted to the plate 42, so that after the plate 42 is fully inserted into the slot 11, the bottom of the plate 42 contacts the bottom of the cage 1, thereby isolating and forming independent feeding chambers 5 in the cage 1. In this embodiment, the cage 1 is isolated into 6 feeding chambers 5 by 5 evenly spaced partition plates 4, which can realize the separate feeding of 6 mice in one cage and avoid the phenomenon of mice crowding together.

[0067] Each feeding chamber 5 is marked with a card above it, indicating the mouse's number. This makes it easy to distinguish the mice. When you need to find a mouse with a specific number, simply look at the number marked on the card in the feeding chamber 5, then open the switch cover 52 to grab the mouse. The operation is simple and convenient, and it can ensure accurate identification of the mouse's number.

[0068] Example 2

[0069] Reference Figure 1 , Figures 5-7 As a further improvement based on Example 1, in this example:

[0070] Two rollers 43 are arranged vertically at both ends of the plate 42. The rollers 43 are rotatably connected to the plate 42 and can roll in contact with the inner wall of the slot 11 when the plate 42 is inserted into the slot 11. The rollers 43 make the process of inserting the plate 42 into the slot 11 smoother.

[0071] The plate 42 has a positioning mark area 44 on the lower part of the outer wall at both the front and rear ends. The front and rear plates of the cage 1 have positioning observation windows 12 on the lower part of the cage. When the plate 42 is fully inserted into the slot 11, the complete positioning mark area 44 can be observed through the positioning observation window 12.

[0072] Two arc-shaped spring pieces 13 are symmetrically arranged on both sides of the inner wall below the slot 11. After the plate 42 is fully inserted into the slot 11, the bottommost roller 43 passes exactly between the two arc-shaped spring pieces 13, and the positioning mark area 44 on the plate 42 completely reaches the area of ​​the positioning observation window 12. The positioning mark area 44 can be a marking image, which can be distinguished from the front and back of the cage 1. For example, in this embodiment, the positioning mark area 44 is a red rectangular area, the cage 1 is not red, the positioning observation window 12 is transparent, and the positioning mark area 44 can be observed with the naked eye after it reaches the area of ​​the positioning observation window 12.

[0073] When the plate 42 of the isolation plate 4 is inserted downward into the slot 11 of the cage 1, the roller 43 is in fixed contact with the inner wall of the slot 11 to ensure smooth insertion. When the bottom roller 43 is pressed against the arc-shaped spring pieces 13 on both sides under downward pressure, the arc-shaped spring pieces 13 are flattened, allowing the roller 43 to pass downward between the two arc-shaped spring pieces 13 (after passing, the arc-shaped spring pieces 13 return to their original shape, which can limit the upward movement of the plate 42. Only when the plate 42 is pulled upward with force can the roller 43 pass upward over the two arc-shaped spring pieces 13, ensuring that...). The stability of the plate 42 prevents it from wobbling or moving upwards due to impacts from mice in the rearing chamber 5, thus avoiding excessively large gaps between the plate 42 and the bottom of the cage 1 that could allow mice to pass through. At this point, the plate 42 is fully inserted into the slot 11 (in place), with its bottom in contact with the bottom of the cage 1. The positioning marking area 44 on the plate 42 is entirely within the area of ​​the positioning observation window 12. The positioning marking area 44 can then be observed through the positioning observation window 12 on the front or rear side of the corresponding rearing chamber 5, thus confirming that the isolation plate 4 is properly installed. This prevents mice from escaping between different rearing chambers 5 due to excessively large gaps at the bottom caused by improper installation of the isolation plate 4.

[0074] Example 3

[0075] Reference Figures 8-10 As a further improvement based on Embodiment 1 or 2, in this embodiment:

[0076] The latching structure 6 between the switch baffle 52 and the cage cover 2, and the latching structure 6 between the cage cover 2 and the cage body 1 are exactly the same, as shown in the following figures.

[0077] The snap-fit ​​structure 6 includes a snap-fit ​​head 61 and a snap-fit ​​seat 62 for snapping the snap-fit ​​head 61; the snap-fit ​​head 61 includes a snap-fit ​​strip body 611, a snap-fit ​​protrusion 612 formed by bending the middle of the snap-fit ​​strip body 611, an mounting portion 613 formed at both ends of the snap-fit ​​strip body 611, and a connecting portion 614 that transitions between the mounting portion 613 and the snap-fit ​​protrusion 612; the middle of the snap-fit ​​protrusion 612 protrudes outward to both sides to form an arc-shaped protrusion 615, and a snap-fit ​​head cavity 616 is formed in the middle;

[0078] The card holder 62 includes a mounting plate 621, a mounting base 622 disposed on the mounting plate 621, and two claws 623 rotatably connected to the mounting base 622 and symmetrically arranged; the two sides of the middle part of the claws 623 are recessed inward to form elastic parts 624, and a clamping cavity 625 is formed between the two claws 623 to accommodate the locking protrusion 612.

[0079] The front end of the pawl 623 is rotatably connected to a pulley 626. After being pressed by the locking protrusion 612, the two pulleys 626 on the two pawls 623 can open outward so that the locking protrusion 612 enters the locking cavity 625.

[0080] In this embodiment, in the snap-fit ​​structure 6 between the switch baffle 52 and the cage cover 2, the snap head 61 is provided at the outer end of the switch baffle 52, and the snap seat 62 is provided at the corresponding position on the cage cover 2.

[0081] In the snap-fit ​​structure 6 between the cage cover 2 and the cage body 1, the snap head 61 is located at the outer end of the cage cover 2, and the snap seat 62 is located at the corresponding position on the cage body 1.

[0082] In this embodiment, a handle 55 is also provided on the switch baffle 52 to facilitate operation of the switch baffle 52.

[0083] Taking the latching structure 6 between the switch baffle 52 and the cage cover 2 as an example, its working principle is as follows:

[0084] When the switch baffle 52 is closed, the switch baffle 52 is pressed down. The engaging protrusion 612 on the locking head 61 at the outer end of the switch baffle 52 presses against the two pulleys 626 on the locking seat 62. Under the pressure of the two pulleys 626, the locking claws 623 rotate outward around their elastic parts 624, so that the two locking claws 623 can open outward, allowing the engaging protrusion 612 to pass down over the two pulleys 626 and enter the locking cavity 625 and stop. During this process, the two arc-shaped protrusions 615 on the engaging protrusion 612 can also shrink and deform inward under the pressure of the pulleys 626, so that the engaging protrusion 612 can smoothly pass over the two pulleys 626. Afterward, the two arc-shaped protrusions 615 return to their original shape. After the engaging protrusion 612 enters the locking cavity 625, it will be stably confined within it without external force, thereby locking the locking seat 62 onto the locking head 61, and ultimately closing and locking the switch baffle 52. When the switch baffle 52 is opened, the handle 55 is pulled upwards, and under external force, the engaging protrusion 612 is pushed upwards and passes over the two pulleys 626, thus unlocking. This latching structure 6 enables quick fixing and unlocking between the switch baffle 52 and the cage cover 2, as well as between the cage cover 2 and the cage body 1, facilitating operation.

[0085] Example 4

[0086] Reference Figures 11-14 As a further improvement based on Example 3, in this example:

[0087] A safety mechanism 7 is also provided on the latching structure 6 between the cage cover 2 and the cage body 1, which is the same as that in embodiment 3. The safety mechanism 7 includes a movable bolt 71 movably connected to the mounting base 622, a connecting rod 72 connected to the outer end of the movable bolt 71, a safety bolt 73 connected to the other end of the connecting rod 72, an iron piece 74 disposed at the inner end of the safety bolt 73, a first bolt hole 75 opened on the mounting plate 621 located in the clamping cavity 625 for the inner end of the safety bolt 73 to be inserted, and a magnetic piece 76 disposed at the bottom of the bolt hole for attracting the iron piece 74.

[0088] The mounting base 622 has a second bolt hole 77 with a diameter larger than that of the movable bolt 71. The inner end of the movable bolt 71 is provided with a limiting ring 78 with an outer diameter larger than that of the second bolt hole 77. The movable bolt 71 can move back and forth (insert and pull out) and rotate within the second bolt hole 77. The limiting ring 78 can prevent the movable bolt 71 from dislodging from the second bolt hole 77.

[0089] The working principle of the insurance mechanism 7 in conjunction with the buckle structure 6 is as follows:

[0090] After the snap-fit ​​head 61 in the snap-fit ​​structure 6 is inserted into the snap-fit ​​seat 62 and locked in place (the principle is the same as in embodiment 3), in order to further ensure the stable connection between the cage cover 2 and the cage body 1 during the handling and transfer of the rat cage, it is necessary to ensure that the snap-fit ​​head 61 will not come off from the snap-fit ​​seat 62. At this time, the safety mechanism 7 provides better protection: first, the safety mechanism 7 is pushed outward to move the movable bolt 71 outward and pull it out. Then, the connecting rod 72 is rotated to push the safety bolt 73 through the snap-fit ​​head cavity 616 of the snap-fit ​​head 61 and insert it into the first bolt hole 75 on the mounting plate 621. The magnetic piece 76 at the bottom of the bolt hole attracts the iron piece 74 at the inner end of the safety bolt 73, so that the safety bolt 73 is fixed in the first bolt hole 75. Since the safety bolt 73 passes through the snap-fit ​​protrusion 612 of the snap-fit ​​head 61, the snap-fit ​​head 61 cannot come off from the snap-fit ​​seat 62. When unlocking the latch structure 6, forcefully pull the safety bolt 73 out of the first bolt hole 75 and completely disengage the safety bolt 73 from the latching protrusion 612, and then pull the latch head 61 out of the latch seat 62.

[0091] By setting up the safety mechanism 7, even if there is some shaking or other external force during the handling and transfer of the rat cage, the locking head 61 is difficult to easily detach from the locking seat 62, thus ensuring a stable connection between the cage cover 2 and the cage body 1.
