Description

Technical Field

[0001] This application relates to the field of laboratory mouse cage technology, and in particular to a non-contact laboratory mouse cage bedding quick replacement device. Background Technology

[0002] Laboratory mouse cages are specialized equipment used to house laboratory mice (such as mice and rats) in scientific research. These cages are typically designed with specific functions to facilitate experimental needs, such as easy observation, control of experimental variables, and ensuring animal health. The design of laboratory mouse cages in a laboratory environment needs to take into account multiple factors such as animal welfare, experimental requirements, and safety.

[0003] During the rearing of laboratory mice, the bedding needs to be changed. Current technology typically involves slowly pouring the bedding out of the cage at an angle into a special waste bag. This method is inconvenient for quickly removing the bedding, resulting in slow bedding replacement and low efficiency, and therefore needs improvement. Utility Model Content

[0004] To address the issue of slow bedding replacement speed, this application provides a non-contact rapid bedding replacement device for laboratory rat cages.

[0005] The non-contact laboratory mouse cage bedding quick replacement device provided in this application adopts the following technical solution:

[0006] A non-contact laboratory mouse cage bedding quick-change device includes a bottom shell and a control mechanism. The control mechanism is located above the bottom shell and includes a top cover that snaps onto the outer surface of the bottom shell. A mouse-proof mesh is snapped onto the inner wall of the bottom shell. A discharge port is opened on the right side of the bottom shell, and a feed port is opened on the left side of the bottom shell. Two guide grooves are opened on the inner wall of the bottom shell. Two sets of guide blocks are slidably connected to the inner wall of each guide groove. A first carrier box and a second carrier box are respectively fixedly installed on the side of the two sets of guide blocks that are close to each other. A groove is opened on the bottom surface of the bottom shell. Two sets of paddles are slidably connected to the inner wall of the groove. Two first springs are fixedly installed on the bottom surface of each paddle. The bottom surface of each first spring is fixedly installed with the inner bottom wall of the groove.

[0007] Optionally, a sliding tube is fixedly connected to the left side of the bottom shell, a T-shaped sliding rod is slidably connected to the inner wall of the sliding tube, a second spring is fixedly installed on the outer surface of the T-shaped sliding rod, and the right end of the second spring is fixedly installed to the left end of the sliding tube.

[0008] By adopting the above technical solution, when replacing the padding material, the T-shaped sliding rod is pushed to move the second carrier box out of the bottom shell. The first spring extends and pushes the lever to rotate, so that the lever applies an upward thrust to the first carrier box. The first carrier box enters the top of the guide groove through the connecting port in the middle of the guide groove via the guide block. The limiting frame limits the first carrier box under the action of the lever. Then, the cleaned second carrier box enters the bottom of the bottom shell through the feed port, and the guide block enters the guide groove. The second carrier box pushes the lever to rotate, so that the lever compresses the first spring. After the right side of the second carrier box contacts the inside of the bottom shell, the guide block is located below the connecting port in the middle of the guide groove. The first spring drives the lever to push the second carrier box upward, so that the second carrier box contacts the first carrier box and limits the first carrier box to prevent it from sliding, thereby completing the rapid replacement of the padding material.

[0009] Optionally, a warning sticker is provided on the front of the bottom shell, and the back of the warning sticker is adhered to the back of the bottom shell and the front of the bottom shell.

[0010] Optionally, two baffles are fixedly installed on the front of the bottom shell, and the two baffles are fixedly installed on the front and back sides of the bottom shell respectively.

[0011] By adopting the above technical solution, the baffle can limit the top cover and prevent it from sliding.

[0012] Optionally, an air vent is provided on the top of the top cover.

[0013] Optionally, the bottom shell is provided with handles on both the left and right sides, and the two handles are fixedly installed on the left and right sides of the bottom shell respectively.

[0014] By adopting the above technical solution, the device can be moved easily, thus facilitating its operation.

[0015] Optionally, a limiting frame is fixedly installed on the inner wall of the bottom shell, and the bottom surface of the limiting frame is in contact with the upper surface of the second carrier box.

[0016] By adopting the above technical solution, the limiting frame can limit the second carrier box and prevent the second carrier box from sliding upward.

[0017] Optionally, each of the guide blocks is adapted to a guide groove.

[0018] By adopting the above technical solution, it is ensured that the guide block can slide inside the guide groove.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When replacing the padding material, push the T-shaped slide bar to move the second carrier box out of the bottom shell. The first spring extends and pushes the lever to rotate, so that the lever applies an upward thrust to the first carrier box. The first carrier box enters the top of the guide groove through the guide block along the connection port in the middle of the guide groove. The limiting frame limits the first carrier box under the action of the lever. Then, the cleaned second carrier box enters the bottom of the bottom shell through the feed port, and the guide block enters the guide groove. The second carrier box pushes the lever to rotate, so that the lever compresses the first spring. After the right side of the second carrier box contacts the inside of the bottom shell, the guide block is located below the connection port in the middle of the guide groove. The first spring drives the lever to push the second carrier box upward, so that the second carrier box contacts the first carrier box and limits the first carrier box to prevent it from sliding, thus completing the quick replacement of the padding material.

[0021] 2. By using a first spring and a paddle, the paddle can push the first and second carrier boxes upwards to move. With the cooperation of the guide block and the guide groove, the first carrier box can move upwards when the paddle pushes it, thus bringing the carrier box into contact with the limiting frame. When the second carrier box moves out of the guide groove, the first carrier box can move upwards under the action of the paddle, thereby quickly replacing the carrier box, improving the efficiency of pad replacement, and ensuring safety by eliminating the need for workers to touch the waste pad.

[0027] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0028] This application discloses a contactless, quick-change device for laboratory mouse cage bedding. (Refer to...) Figure 1 A non-contact laboratory mouse cage bedding quick-change device includes a base shell 1, a control mechanism 2 on top of the base shell 1, and a top cover 201 snapped onto the outer surface of the base shell 1. Two baffles 3 are fixedly installed on the front of the base shell 1, with their adjacent sides fixed to the front and back of the base shell 1 respectively. The baffles 3 limit the top cover 201, preventing it from sliding. A ventilation port 4 is provided on the top of the top cover 201 for air exchange. Pull handles 101 are provided on both the left and right sides of the base shell 1, with their adjacent sides fixed to the left and right sides respectively. The pull handles 101 allow the device to be moved for easy operation.

[0029] Reference Figure 2 and Figure 3 The inner wall of the bottom shell 1 is fitted with a rodent-proof mesh 205. A discharge port 203 is located on the right side of the bottom shell 1, and a feed port 206 is located on the left side of the bottom shell 1. Figure 4 The inner wall of the bottom shell 1 has two guide grooves 202. Two sets of guide blocks 212 are slidably connected to the inner wall of each guide groove 202. A first carrier box 207 and a second carrier box 211 are fixedly installed on the side of the two sets of guide blocks 212 that are close to each other. Each guide block 212 is adapted to the guide groove 202, ensuring that the guide block 212 can slide inside the guide groove 202. A groove 208 is formed on the bottom surface of the bottom shell 1. Two sets of levers 209 are slidably connected to the inner wall of the groove 208. Two first springs 210 are fixedly installed on the bottom surface of each lever 209, and the bottom surface of each first spring 210 is fixedly installed to the inner bottom wall of the groove 208. A limiting frame 204 is fixedly installed on the inner wall of the bottom shell 1. The bottom surface of the limiting frame 204 contacts the upper surface of the second carrier box 211, limiting the second carrier box 211 and preventing it from sliding upwards.

[0030] Reference Figure 1 A sliding tube 6 is fixedly connected to the left side of the bottom shell 1. A T-shaped sliding rod 602 is slidably connected to the inner wall of the sliding tube 6. A second spring 601 is fixedly installed on the outer surface of the T-shaped sliding rod 602. The right end of the second spring 601 is fixedly installed to the left end of the sliding tube 6. The second carrier box 211 can be easily pushed to move through the sliding tube 6 and the T-shaped sliding rod 602, so as to push the second carrier box 211 out.

[0031] When replacing the padding material, push the T-shaped slide bar 602 to push the second carrier box 211, causing the padding material inside the second carrier box 211 to slide. As the second carrier box 211 moves out of the bottom shell 1, the operator can remove the second carrier box 211. As the second carrier box 211 moves out, the first spring 210 extends, and the first spring 210 pushes the lever 209 to rotate, causing the lever 209 to push the first carrier box 207 upward to apply a pushing force. The first carrier box 207 enters the top of the guide groove 202 through the connecting port in the middle of the guide groove 202 via the guide block 212, and moves upward with the limiting frame 204. Under the action of the lever 209, the first carrier box 207 is limited.

[0032] The cleaned second carrier box 211 is then introduced into the bottom of the bottom shell 1 through the feed port 206, and the guide block 212 enters the guide groove 202. As the second carrier box 211 enters, it pushes the lever 209 to rotate, compressing the first spring 210. After the right side of the second carrier box 211 contacts the inside of the bottom shell 1, the guide block 212 is located below the connection port in the middle of the guide groove 202. Under the action of the spring, the lever 209 can push the second carrier box 211 upward, so that the second carrier box 211 contacts the first carrier box 207 and limits the first carrier box 207 to prevent it from sliding, thereby completing the rapid replacement of the pad material.

[0033] Reference Figure 1 A warning sticker 5 is provided on the front of the bottom shell 1. The back of the warning sticker 5 is attached to the back of the bottom shell 1 and the front of the bottom shell 1. The warning sticker 5 can warn non-staff members and prevent them from touching the device.

[0034] The implementation principle of the contactless laboratory mouse cage bedding quick replacement device in this application embodiment is as follows: When replacing the bedding, the T-shaped slide bar 602 is pushed, and the T-shaped slide bar 602 moves to push the second carrier box 211 out of the bottom shell 1. The first spring 210 extends and pushes the lever 209 to rotate, so that the lever 209 applies an upward pushing force to the first carrier box 207. The first carrier box 207 enters the top of the guide groove 202 through the connecting port in the middle of the guide groove 202 via the guide block 212. The limiting frame 204 limits the first carrier box 207 under the action of the lever 209. Then, the cleaned second carrier box 211 enters the bottom of the bottom shell 1 through the feed port 206, and the guide block 212 enters the guide groove 202. The second carrier box 211 pushes the paddle 209 to rotate, so that the paddle 209 compresses the first spring 210. After the right side of the second carrier box 211 contacts the inside of the bottom shell 1, the guide block 212 is located below the connection port in the middle of the guide groove 202. Under the action of the spring, the paddle 209 can push the second carrier box 211 to move upward, so that the second carrier box 211 contacts the first carrier box 207 and limits the first carrier box 207 to prevent the first carrier box 207 from sliding, thereby completing the rapid replacement of the pad material.

[0035] 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.
