Description

Technical Field

[0001] The utility model relates to the technical field of rapid mouse retrieval, and more specifically, to experimental mouse breeding equipment for rapid mouse retrieval. Background Art

[0002] In many scientific fields such as experimental biology, pharmacology and medicine, mice have always been the most popular experimental subjects. Because their physiological structure is similar to that of humans, they reproduce quickly and have a short life cycle, making mice an ideal model for scientists to explore the mysteries of life and test the efficacy and toxicity of new drugs. However, in the preparation stage of the experiment, researchers always encounter a difficult and critical problem: how can these agile little creatures be captured safely and effectively from dense breeding cages?

[0003] Mice are naturally alert and quick-moving, and are extremely vigilant to any changes in their environment. This nature makes manual capture extremely difficult. Experimenters often need to spend a lot of time and energy to capture mice in cages, but the results are often unsatisfactory. What's worse is that due to the sharp teeth of mice, experimenters may be bitten if they are not careful during the capture process, which not only causes physical harm, but also may cause health risks due to viruses or bacteria that mice may carry.

[0004] The capture methods currently used in laboratories, such as directly grabbing with hands or using simple capture devices, are simple and easy to use, but have many disadvantages. First, these methods have greatly reduced capture efficiency, especially when a large number of mice are needed for experiments. This inefficient capture method will seriously affect the progress of the experiment. Secondly, the potential safety hazards these methods bring to experimenters cannot be ignored. Even for experienced experimenters, it is difficult to completely avoid the risk of being bitten during frequent capture operations. Finally, these traditional methods often cause great psychological pressure and physiological stress on mice, which may affect their physiological state and interfere with the accuracy of the experimental results.

[0005] Therefore, in order to solve the above technical problems, the present application proposes an experimental mouse breeding device for quickly taking mice. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an experimental mouse breeding device for quickly taking mice.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a laboratory mouse breeding device for quickly taking mice, comprising:

[0008] A breeding cage, wherein a mouse retrieval box is installed on the breeding cage, and the breeding cage is connected to the mouse retrieval box through a passage, and a baffle is slidably connected to the mouse retrieval box, and the baffle can separate the breeding cage from the mouse retrieval box to prevent mice from accidentally entering the mouse retrieval box;

[0009] A delivery tube installed on the mouse retrieval box, the delivery tube is connected to the inside of the mouse retrieval box through a connection groove provided in the mouse retrieval box, and a mouse trap is movably connected to one end of the delivery tube away from the mouse retrieval box, the mouse trap includes a movable plate rotatably connected to the mouse retrieval box, and the mouse trap is used to clamp the mouse;

[0010] The corresponding delivery pipe is installed in a mouse catching mechanism in the mouse catching box, and the mouse catching mechanism is used to catch mice.

[0011] Preferably, the mouse catching mechanism includes a movable plate installed in the mousetrap corresponding to the connecting groove, the movable plate is rotatably connected in the mouse catching box through a transmission rod, a torsion spring is installed on the transmission rod, and one end of the transmission rod extends out of the mouse catching box and is connected to a knob, one end of the torsion spring is installed on the mouse catching box, and the mouse catching mechanism also includes a limit rod installed on the mousetrap through a spring, a limit block is connected to the limit rod, and the limit block is arranged corresponding to the position of the movable plate.

[0012] Preferably, the mousetrap comprises two stacked grids, which are connected by a plurality of elastic bands. The two grids are pulled to cause the grids to stretch the elastic bands and to be put on the conveying tube. When the mouse falls from the conveying tube, it hits the grids, thereby driving the mousetrap to leave the conveying tube and clamp the mouse inside to prevent it from running away.

[0013] Preferably, a bait for attracting mice is placed in the mouse retrieval box at a position corresponding to the movable plate;

[0014] It is worth noting that the bait can be the food that mice like, or an object that can attract mice.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, the connection between the breeding cage and the mouse retrieval box is controlled by the baffle plate, so as to control whether the mice can enter the mouse retrieval box. The mice enter the mouse retrieval box, fall into the conveying pipe through the movable plate, and fall into the connected mouse trap through the conveying pipe, so as to realize the rapid capture of the mice and reduce human contact to avoid accidental injury to the staff, thereby solving the problems in the prior art that the capture of mice is complicated, difficult to catch, time-consuming and dangerous.

[0017] 2. In the utility model, by turning the knob, the transmission rod drives the movable plate to rotate and compresses the torsion spring at the same time. When the movable plate rotates, it squeezes the limit block, causing the limit rod to compress the spring, thereby allowing the movable plate to rotate. After the movable plate rotates, the limit rod drives the limit block to limit the movable plate under the elastic force of the spring. When the mouse walks onto the movable plate, it squeezes the movable plate, causing the movable plate to compress the limit block and move inward, thereby causing the movable plate to rotate again, causing the mouse to fall into the conveying pipe below.

[0026] like Figure 1-6 As shown, the utility model provides an experimental mouse breeding device for quickly taking mice, comprising a breeding cage 1, a mouse taking box 2 is installed on the breeding cage 1, and the breeding cage 1 is connected to the mouse taking box 2 through a passage 7, and a baffle 8 is slidably connected to the mouse taking box 2, and the baffle 8 can separate the breeding cage 1 from the mouse taking box 2 to prevent mice from accidentally entering the mouse taking box 2;

[0027] A delivery pipe 3 installed on the mouse retrieval box 2, the delivery pipe 3 is connected to the inside of the mouse retrieval box 2 through a connection groove 6 provided in the mouse retrieval box 2, and a mouse trap 4 is movably connected to one end of the delivery pipe 3 away from the mouse retrieval box 2, the mouse trap 4 includes a movable plate 51 rotatably connected to the mouse retrieval box 2, and the mouse trap 4 is used to clamp the mouse;

[0028] The corresponding delivery pipe 3 is installed in the mouse catching box 2, and the mouse catching mechanism 5 is used to catch mice;

[0029] In summary, compared with the problem that the existing mouse breeding cage 1 is inconvenient to take out the mice, the present invention controls the communication between the breeding cage 1 and the mouse retrieval box 2 by the baffle 8, and can control whether the mice can enter the mouse retrieval box 2. The mice enter the mouse retrieval box 2, pass through the movable plate 51 and fall into the conveying pipe 3, and then fall into the connected mouse trap 4 through the conveying pipe 3, so as to realize the rapid capture of the mice, reduce human contact, and avoid accidental injury to the staff;

[0030] The mouse trap 4 includes two stacked net frames 41, which are connected by multiple elastic bands 42. The two net frames 41 are pulled to stretch the elastic bands 42 and put on the conveying tube 3. When the mouse falls from the conveying tube 3, it hits the net frames 41, thereby driving the mouse trap 4 to leave the conveying tube 3 and clamp the mouse inside to prevent it from running away.

[0031] The mouse trap mechanism 5 includes a movable plate 51 installed in the mousetrap corresponding to the connection slot 6. The movable plate 51 is rotatably connected to the mousetrap box 2 through a transmission rod 52. A torsion spring 53 is installed on the transmission rod 52. One end of the transmission rod 52 extends out of the mousetrap box 2 and is connected to a knob 54. One end of the torsion spring 53 is installed on the mousetrap box 2. The mouse trap mechanism 5 also includes a limit rod 55 installed on the mousetrap through a spring 56. A limit block 57 is connected to the limit rod 55. The limit block 57 is arranged corresponding to the position of the movable plate 51.

[0032] Among them, a bait 9 for attracting mice is placed at a position corresponding to the movable plate 51 in the mouse removal box 2;

[0033] It is worth noting that the bait 9 can be food that the mice like, or an item that can attract the mice;

[0034] It should be noted that the bait 9 can be used to enhance the attraction of the mice, or the bait 9 can be omitted, and the mice can be brought into the mouse retrieval box 2 by natural activities of the mice or human factors;

[0035] When taking the mouse, first hold the two mesh frames 41 and pull the two mesh frames 41 in opposite directions, the elastic band 42 is stretched and put on the conveying tube 3;

[0036] The number of mice to be taken out is determined according to the experiment to be performed, and the knob 54 is rotated the same number of times. The knob 54 drives the movable plate 51 to rotate through the transmission rod 52, and the torsion spring 53 is compressed during the rotation. When the movable plate 51 rotates one circle, the limit rod 55 will be squeezed by the movable plate 51, and the compression spring 56 will move inward. After the movable plate 51 rotates, the limit block 57 and the limit rod 55 will be stuck on the movable plate 51 again under the elastic force of the spring 56. After the movable plate 51 rotates, the limit block 57 and the limit rod 55 will limit the position of the movable plate 51, so that the movable plate 51 cannot rotate even under the elastic force of the torsion spring 53.

[0037] It is worth noting that in order to avoid excessive elastic force of the torsion spring 53, the number of mice to be taken at a time needs to be within three, and more mice can be taken to perform multiple rotations;

[0038] Then, the baffle plate 8 is pulled out from the passage 7, and the mouse is allowed to enter the mouse retrieval box 2 through natural movement, artificial driving, or attraction by the bait 9. When the mouse passes through the movable plate 51, its own weight will press the movable plate 51, and the weight of the mouse will destroy the dynamic balance between the movable plate 51 and the limit block 57, so that the movable plate 51 presses the limit block 57 under the elastic force of the torsion spring 53 and the weight of the mouse, so that the limit block 57 compresses the spring 56 through the limit rod 55 and moves toward the inner wall of the mouse retrieval box 2, and the movable plate 51 is no longer limited. The movable plate 51 rotates, so that the mouse slides into the conveying pipe 3 and is captured by the mouse trap 4.

[0039] It is worth noting that the elastic force of the torsion spring 53 and the elastic force of the spring 56 are much smaller than the weight of the mouse, so that the weight of the mouse can easily destroy the dynamic balance between the movable plate 51 and the limit block 57;

[0040] It should be noted that the upper and lower sides of the limit block 57 are beveled to facilitate being squeezed and moved by the movable plate 51;

[0041] Since the original mouse has fallen into the conveying tube 3, if the movable plate 51 rotates for multiple turns driven by the knob 54, the torsion spring 53 still has the elastic force to drive the movable plate 51 to rotate. At this time, the limit block 57 limits the movable plate 51 again under the elastic force of the spring 56. Similarly, when a new mouse passes through the movable plate 51, its own weight will squeeze the movable plate 51, and the weight of the mouse will once again destroy the power balance between the movable plate 51 and the limit block 57, so that the new mouse falls into the conveying tube 3 until the torsion spring 53 loses its elastic force. Since the elastic force of the torsion spring 53 is determined by how many turns the knob 54 drives the movable plate 51 to rotate, it can finally be achieved that the number of captured mice can be controlled according to the number of turns the knob 54 is turned.

[0042] It should be noted that when capturing multiple mice, the mouse trap 4 can be replaced with other containers, or the mouse trap 4 can be replaced after the previous mouse is captured, so as to achieve automatic, accurate and efficient capture of mice.

[0043] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form. Any ordinary technician in the industry can smoothly implement the utility model as shown in the drawings of the specification and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the utility model using the technical content disclosed above are all equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the utility model are still within the protection scope of the technical solution of the utility model.
