Description

Technical Field

[0001] The invention relates to the technical field of experimental animal monitoring, in particular to a feeding device for observing the vital signs of experimental rats. Background Art

[0002] In the process of new drug development, animal nutrition, brain science, etc., it is usually necessary to place experimental animals in corresponding cages to track experimental results, and at the same time ensure the healthy living environment of experimental animals. White mice are the most common experimental animals, accounting for more than 90% of experimental animals. It has a wide range of uses. Medicine, production of vaccines and biological drugs, surgical practice drills, quality inspection and safety evaluation of new drugs, food and drugs, research in life sciences, etc., all rely on the contribution of experimental white mice. When white mice are used to monitor vital signs in experiments, multiple white mice are usually placed inside the breeding box, and the monitoring sensors are installed inside the breeding box or worn on the white mice for monitoring.

[0003] Existing white rat vital signs monitoring equipment usually consists of an instrument connected to a monitoring sensor and a breeding box. Multiple breeding boxes are placed on a placement rack. When the white rat needs to be taken out, the breeding box needs to be removed from the placement rack, and then the grille cover above the breeding box is opened to catch the white rat from the inside of the breeding box. White rats are small in size, and when people catch white rats, the white rats will run inside the breeding box, making it inconvenient to quickly catch the required white rats. In addition, a layer of bedding is laid at the bottom of the breeding box to absorb the urine and feces of the white rats and keep the inside of the breeding box dry and hygienic. The bedding is usually replaced every two weeks or so, which easily causes the upper bedding to stick together and the lower bedding to be insufficiently utilized, making it inconvenient to break up and turn over the bedding.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Drive multiple push plates to rotate through the rotating rod, so that the push plates rotate to a vertical state, connect the partition plate and the grille cover plate through the connecting rope, and drive the partition plate to move up while the grille cover plate is opened, so that the grille cover plate drives the multiple partition plates below to move up by flipping the grille cover plate, thereby dividing the breeding box into multiple spaces and separating multiple mice.

[0032] 2. When the rotating rod rotates inside the slider, the slide bar slides inside the slide rail, adjusts the angle of the push plate, and drives the push plate to flip to a vertical state. At this time, the slide bar moves to the exit, and the push plate continues to move up to move the slide bar out of the slide rail. Conversely, when storing the push plate, after the slide bar moves to the inside of the slide rail, the electromagnet works and repels the push plate to flip to a vertical state through the principle of like poles repelling each other, so that the partition moves down and can drive the push plate to flip to a horizontal state and store it.

[0033] 3. Turn the handle, and the two reel drums rotate synchronously. One of the two pull ropes on the surface is released, and the other is reeled in. Pull the slider to slide along the upper end of the partition, drive the push plate to move, and narrow the movement range of the mouse. By pulling the push plate to move, the activity space of the mouse is limited, making it easier for the experimenter to quickly grab the required mouse.

[0034] 4. When the push plate moves, the roller rotates, and the multiple round rods on its surface knock and turn over the bedding at the bottom of the breeding box. Therefore, when the push plate moves, the bedding at the bottom of the breeding box is hit and stirred, breaking up and turning over the bedding, avoiding the upper bedding sticking together into blocks, resulting in insufficient utilization of the lower bedding, thereby improving the utilization rate of the bedding.

[0035] 5. Through the electromagnet, the push plate can be flipped in a specific direction when stored. At the same time, the magnetic pole of the electromagnet can be adjusted to make the electromagnet attract the push plate and keep the push plate vertical when moving to the electromagnet, so that the slide rod can be inserted into the exit and enter the interior of the slide rail.

[0048] Specifically, bedding is laid at the bottom of the breeding box 201, an external monitoring device is placed behind the rack 1, and multiple monitoring clamps 101 are connected so that the monitoring clamps 101 pass through the gaps in the grille cover 203 and are clamped on the necks of the white mice. Various data of the white mice's vital signs are detected and recorded. The partition component 3 divides the interior of the breeding box 201 into multiple spaces to separate multiple white mice. Then, by moving the push plate 402, the activity range of the white mice is reduced. When the push plate 402 moves, the bedding at the bottom of the breeding box 201 is knocked and flipped by the flipping component 5.

[0049] Embodiment 1

[0050] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, multiple partitions 303 slide through the through grooves 206 at corresponding positions respectively, an L-shaped card plate 306 is fixedly installed at one end of the upper surface of the partition 303, a slider 307 is slidably inserted inside the L-shaped card plate 306, and a U-shaped plate 308 is fixedly connected to the upper ends of the two outermost partitions 303, and a connecting rope 309 is fixedly connected between the U-shaped plate 308 and the grille cover 203.

[0051] In this embodiment, the position of the slider 307 is limited by the L-shaped card plate 306, and a small electromagnet is arranged inside the L-shaped card plate 306 so that the electromagnet can attract the iron slider 307, fix the slider 307, and keep the slider 307 stationary when the partition 303 moves up. The rotating rod 401 drives multiple push plates 402 to rotate, so that the push plates 402 rotate to a vertical state, and the partition 303 and the grille cover 203 are connected by a connecting rope 309. When the grille cover 203 is opened, the partition 303 is driven to move up, so that they move at the same time, so that by flipping the grille cover 203, the grille cover 203 drives the multiple partitions 303 below to move up, so that the breeding box 201 is divided into multiple spaces, so that multiple white mice are separated.

[0052] like Figure 4 , Figure 6 and Fig. 9 As shown, in this embodiment, the rotating rod 401 passes through multiple sliders 307 and is rotatably connected to the sliders 307. Multiple slide rails 404 are equidistantly fixedly embedded and installed on the lower surface of the interior of the breeding box 201. A slide rod 403 is fixedly installed on the lower end surface of the push plate 402. The slide rod 403 is slidably connected to the slide rail 404. An exit 405 for moving the slide rod 403 out is opened at one end of the upper surface of the slide rail 404.

[0053] During specific implementation, when the rotating rod 401 rotates inside the slider 307, the sliding rod 403 slides inside the slide rail 404, adjusts the angle of the push plate 402, and drives the push plate 402 to flip to a vertical state. At this time, the sliding rod 403 moves to the exit 405, and the push plate 402 continues to move upward to move the sliding rod 403 out of the slide rail 404. Conversely, when storing the push plate 402, after the sliding rod 403 moves to the inside of the slide rail 404, the electromagnet 207 works, and through the principle of like poles repelling each other, the push plate 402 is repelled from flipping to a vertical state, so that the partition 303 can drive the push plate 402 to flip to a horizontal state after moving downward, and store it.

[0054] like Figure 2 , Figure 5 and Figure 7 As shown, in this embodiment, the pulling component 6 includes: an installation frame 601 fixedly installed on one end surface of the fixed frame 302, two winding drums 602 are symmetrically rotatably connected to the two ends of the installation frame 601, a plurality of pull ropes 603 are respectively wound around the outer surfaces of the two winding drums 602, and two movable pulleys 606 are rotatably connected to the other end surface of the fixed frame 302 through a bracket; a synchronous belt assembly 604 is fixedly connected to the upper end of the outer surface of the two winding drums 602, and a rotating handle 605 is fixedly installed on the upper end of the two winding drums 602; a pull rope 603 on the outer surface of the winding drum 602 movably passes through the slide groove 205 and the partition plate 303 and is fixedly connected to one side surface of the outermost slider 307, and another pull rope 603 on the outer surface of the winding drum 602 bypasses the movable pulley 606, and movably passes through the slide groove 205 and the L-shaped clamping plate 306 and is fixedly connected to the other side surface of the outermost slider 307.

[0055] During specific implementation, the handle 605 is rotated, and the two winding drums 602 are rotated synchronously through the transmission of the synchronous belt assembly 604. The two pull ropes 603 on the surface are released and wound up at the same time, and the slider 307 is pulled to slide along the upper end of the partition 303, driving the push plate 402 to move, thereby reducing the moving range of the white mouse. By pulling the push plate 402 to move, the activity space of the white mouse is limited, making it convenient for the experimenter to quickly grab the required white mouse.

[0056] like Figure 4 and Figure 8As shown, in this embodiment, the flip assembly 5 includes: a plurality of No. 1 support rings 501 are respectively fixedly installed on the surface of one side of the plurality of push plates 402, a No. 1 rotating shaft 502 is rotatably connected to the inside of the plurality of No. 1 support rings 501, a plurality of No. 2 support rings 503 are respectively fixedly installed at the lower end of the surface of one side of the plurality of push plates 402, and a plurality of paddle rollers 504 are respectively rotatably connected to the inside of the plurality of No. 2 support rings 503; a protective shell 505 is symmetrically fixedly installed on the surface of one side of the push plate 402, a No. 2 rotating shaft 506 is rotatably connected between the two protective shells 505, and the No. 1 rotating shaft 502 and the shifting roller 504 respectively penetrate the adjacent protective shells 505 and are rotatably connected with the protective shells 505; inside the protective shell 505, bevel gears 507 are fixedly installed on the outer surface of the No. 1 rotating shaft 502, the outer surface of the shifting roller 504 and the two end surfaces of the No. 2 rotating shaft 506, and the two adjacent bevel gears 507 are meshingly connected to each other, and a plurality of gears 509 meshingly connected to the rack 305 are equidistantly fixedly installed on the outer surface of the No. 1 rotating shaft 502, and a brush plate 508 is fixedly connected to one side of the gear 509 between two adjacent No. 1 support rings 501.

[0057] In specific implementation, when the push plate 402 moves, the gear 509 rotates on the surface of the rack 305, driving the No. 1 rotating shaft 502 to rotate, and through the transmission of the bevel gear 507, the No. 2 rotating shaft 506 drives the paddle roller 504 to rotate, so that the multiple round rods on the surface of the paddle roller 504 knock and turn over the padding at the bottom of the breeding box 201, so that when the push plate 402 moves, the padding at the bottom of the breeding box 201 is hit and stirred, and the padding is broken up and turned over to avoid the upper padding sticking into blocks and causing insufficient utilization of the lower padding, thereby improving the utilization rate of the padding. The bristles of the brush plate 508 brush over the rack 305, brush off the padding on its surface, and avoid it affecting the meshing of the gear 509 and the rack 305. The protective shell 505 protects the bevel gear 507 to prevent the padding from affecting the meshing between the bevel gears 507.

[0058] Embodiment 2

[0059] On the basis of the first embodiment, in order to make up for the problem in the first embodiment that it is inconvenient to retract the slide rod 403 into the slide rail 404 after the push plate 402 moves to the initial position.

[0061] During specific implementation, the material blocking rod 204 is used to block the feeding area above the grille cover 203 to prevent feed from falling when the grille cover 203 is flipped. The electromagnet 207 is used to enable the push plate 402 to be flipped in a specific direction during storage. At the same time, the magnetic pole of the electromagnet 207 can be adjusted so that the electromagnet 207 attracts the push plate 402 and keeps the push plate vertical when moving to the electromagnet 207, so that the slide rod 403 can be inserted into the outlet 405 and enter the interior of the slide rail 404.
