Description

Technical Field

[0001] The utility model relates to the technical field of mousetraps, in particular to a mole-shaped mousetrap with a built-in tunnel. Background Art

[0002] Mole voles are small mammals belonging to the order Rodentia, family Muridae, and genus Mole Vole. They are mainly distributed in the temperate regions of Eurasia and prefer to live in humid, densely vegetated environments. Mole voles are small in size, usually between 10-15 cm in length and weigh between 50-100 grams. Their fur is mostly brown or gray, with a lighter color on the abdomen. Mole voles have small eyes and ears, well-developed forelimbs, and are good at digging burrows. They mainly feed on plants, including roots, stems, leaves, fruits, and seeds, etc. The mousetrap is a device used to capture harmful animals such as mole voles, mainly composed of a bait box, bait, a trigger device, and a capture device. The bait box is used to place bait and attract mole voles, and the bait is the key to attracting mole voles into the mousetrap. The trigger device is a key component of the mousetrap, which is used to detect the entry of mole voles and activate the capture device. The capture device is an executive component used to capture mole voles. Common ones include wire mesh, spring clamps, trap doors, etc.

[0003] For example, a mousetrap for voles built into a tunnel disclosed in the authorization announcement number CN212035641U includes a rotating shaft, a trigger mechanism, an upper mousetrap mechanism and a lower mousetrap mechanism, wherein the lower mousetrap mechanism is provided on the surface of the rotating shaft to rotate around, a lower mousetrap rod is fixedly provided at one end of the lower mousetrap mechanism, a lower pressing rod is fixedly provided at the other end of the lower mousetrap mechanism, a support rod is provided on the surface of the lower pressing rod to rotate around, a tail hook is fixedly provided at one end of the support rod, an upper mousetrap mechanism is provided on one side of the lower mousetrap mechanism, which inserts one end of the mousetrap into the hole, and the vole is caught in the hole. When exiting the hole, it will inevitably hit the mouse-blocking rod, thereby driving the resistance rod to rotate, the support rod loses its supporting function, and the torsion spring drives the upper mouse clamp rod and the lower mouse clamp rod to clamp instantly to complete the mouse capture. However, after completing a mouse capture action, the above technical solution also loses its own mouse-catching function, and it is necessary to wait for the staff to pick up and readjust the mousetrap to the clamping state. During the waiting process for debugging, it is difficult for the mole voles inside and outside the hole to enter and exit through the hole and be captured. This is inefficient for large farmlands or forest areas, and it is difficult to respond to the invasion of mole voles in a timely manner. Utility Model Content

[0004] The utility model aims to provide a mousetrap for a mole vole built in a tunnel, wherein a mousetrap cage is limited at the entrance and exit of the mole vole through two elastic supporting legs, and both ends of the mousetrap cage are hingedly provided with flippable circular baffles, which allow the mole vole to enter the interior of the mousetrap cage. After the mole vole enters the mousetrap cage, the circular baffles close automatically under the action of gravity and an elastic reset structure, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tunnel-built mole-shaped vole mousetrap, comprising a mousetrap cage and a notched annular plate fixed at both ends of the mousetrap cage, an inner tube is fixed inside the notched annular plate, two symmetrical convex feet are installed at the top of the inner tube, a rotating shaft is rotatably installed between the two convex feet, a bending arm is welded on the outer wall of one side of the rotating shaft close to the inside of the mousetrap cage, and a circular baffle for closing a port of the inner tube is installed on the outer wall of one side of the bending arm, an elastic reset structure for blocking the deflection of the rotating shaft is installed on the outer walls of the convex feet, a trumpet-shaped inlet cover is fixed at one end of the mousetrap cage, and an elastic support foot in contact with the inner wall of the tunnel is provided on the outer peripheral surface of the mousetrap cage on one side of the trumpet-shaped inlet cover.

[0006] Preferably, the mousetrap cage is composed of two keel rings and a plurality of equally spaced transverse ribs welded between the two keel rings.

[0007] Preferably, the length of the mousetrap is 45 cm to 60 cm.

[0008] Preferably, the inner tube, the circular baffle door and the bending arm are all made of hard plastic material.

[0009] Preferably, the elastic reset structure includes a U-shaped seat fixed on the outer wall of one side of the protruding foot and a notch disk arranged on one side of the U-shaped seat, one end of the rotating shaft passes through the outside of the U-shaped seat and is fixedly connected to one side of the outer wall of the notch disk, and the outer peripheral surface of the rotating shaft is provided with a first torsion spring, and the two end portions of the first torsion spring are respectively clamped with the bottom end of the U-shaped seat and one side of the outer wall of the notch disk.

[0010] Preferably, the elastic support leg comprises an outer support ring welded to the outer circumference of the mousetrap cage, two symmetrical rectangular hollow grooves arranged on the outer circumference of the outer support ring, a second torsion spring mounted inside the rectangular hollow groove, and a U-shaped foot support integrally formed at both ends of the U-shaped foot support.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the tunnel-built mole vole mousetrap is provided with a circular baffle door and a mousetrap cage and other structures that cooperate with each other. The circular baffle door allows the mole vole to freely enter the mousetrap cage, thereby reducing the mole vole's vigilance against previous mousetraps, and when the mole vole enters the mousetrap cage, the circular baffle door closes automatically under the action of gravity and the elastic reset structure, so that the mole vole cannot escape. There is no need for staff to pick up and readjust the mousetrap in time, which reduces the need for human intervention, helps to reduce working time and labor costs, and improves mouse catching efficiency, reducing the damage of mole voles to crops.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5The utility model provides an embodiment: a mousetrap for a mole vole built in a tunnel, comprising a mousetrap 1 and a notched annular plate 2 fixed at both ends of the mousetrap 1, and an inner tube 4 is fixed inside the notched annular plate 2, two symmetrical convex feet 5 are installed at the top of the inner tube 4, a rotating shaft 6 is rotatably installed between the two convex feet 5, a bending arm 7 is welded on the outer wall of the rotating shaft 6 close to the inside of the mousetrap 1, and a circular baffle 8 for closing one end of the inner tube 4 is installed on the outer wall of one side of the bending arm 7, and an elastic reset structure 10 for blocking the deflection of the rotating shaft 6 is installed on the outer wall of the convex feet 5, and a trumpet-shaped inlet cover 3 is fixed at one end of the mousetrap 1. When the mole vole returns to the cave, the trumpet-shaped inlet cover 3 makes it easier for the mole vole to enter the inside of the mousetrap 1 through the notched annular plate 2 and the inner tube 4, and an elastic support foot 12 in contact with the inner wall of the tunnel is provided on the outer peripheral surface of the mousetrap 1 on one side of the trumpet-shaped inlet cover 3;

[0020] Since the mousetrap 1 is fixed at the entrance and exit of the mole vole through the elastic legs 12, non-target animals such as poultry and livestock can be effectively prevented from mistakenly entering the mousetrap 1. At the same time, the inner space of the mousetrap 1 is more spacious, which can provide appropriate activity space for the captured mole vole, reducing its struggle and injury risks;

[0021] The mousetrap 1 is composed of two keel rings 101 and a plurality of equally spaced transverse ribs 102 welded between the two keel rings 101. The length of the mousetrap 1 is 45 cm to 60 cm. It has a simple structure, is firm and stable, and can be placed in advance during the peak activity period of mole voles to improve the mouse catching effect.

[0022] The elastic support leg 12 includes an outer support ring 11 welded to the outer circumference of the mousetrap cage 1, two symmetrical rectangular hollow grooves 1201 arranged on the outer circumference of the outer support ring 11, a second torsion spring 1202 set inside the rectangular hollow groove 1201, and U-shaped support legs 1203 integrally formed at both ends of the U-shaped support legs 1203. The staff can insert the mousetrap cage 1 into the hole and make the U-shaped support legs 1203 rest against the inner wall of the hole. At this time, the second torsion spring 1202 is deformed to a certain extent, so that the mousetrap cage 1 can be placed stably.

[0023] The inner tube 4, the circular baffle 8, and the bending arm 7 are all made of hard plastic material, which has a light weight, making the entire mousetrap 1 lighter and easier to install and carry;

[0024] The elastic reset structure 10 includes a U-shaped seat 9 fixed on the outer wall of one side of the convex foot 5 and a notched disk 1001 arranged on one side of the U-shaped seat 9. One end of the rotating shaft 6 passes through the outside of the U-shaped seat 9 and is fixedly connected to the outer wall of one side of the notched disk 1001. The outer peripheral surface of the rotating shaft 6 is covered with a first torsion spring 1002. The two ends of the first torsion spring 1002 are respectively engaged with the bottom end of the U-shaped seat 9 and the outer wall of one side of the notched disk 1001. When the circular baffle 8 is pushed and deflected by the mole vole, the bending arm 7 drives the rotating shaft 6 and the notched disk 1001 to rotate. Since the two ends of the first torsion spring 1002 are respectively engaged on the U-shaped seat 9 and the notched disk 1001, the first torsion spring 1002 is torsionally deformed. When the mole vole passes through the circular baffle 8, the circular baffle 8 will be quickly reset under the action of gravity and the elastic force of the first torsion spring 1002 to ensure the rapid closure of the port of the mousetrap 1.

[0025] When the embodiment of the present application is in use, the staff first takes out the mousetrap and limits the mousetrap cage 1 in the mousetrap at the entrance and exit of the mole vole through two elastic legs 12. It is necessary to put bait in the mousetrap cage 1 in advance. At this time, one end of the mousetrap cage 1 with the trumpet-shaped inlet cover 3 faces the outside of the hole, and the other end of the mousetrap cage 1 faces the inside of the hole, so that both ends of the mousetrap cage 1 can be used for the mole vole to enter and exit. When the mole vole is attracted by the bait inside the mousetrap cage 1 and enters the mousetrap cage 1, the mole vole will break through the obstruction of the circular baffle 8 through the inner tube 4, and the circular baffle 8 will drive the rotating shaft 6 to deflect. At this time, the elastic reset structure 10 is deformed and generates elastic force under the rotation of the rotating shaft 6. When the mole vole passes through the circular baffle 8 and is about to enter the interior of the mousetrap cage 1, the circular baffle 8 and the curved baffle 8 will be deformed and generate elastic force. The folding arm 7 will be reset under the action of gravity and the elastic force of the elastic reset structure 10, so that the ends of the inner tube 4 and the mousetrap 1 are in a closed state. At this time, the mole vole inside the mousetrap 1 cannot escape, and the mouse catching function is achieved. The mousetrap then returns to a normal working state, waiting for and attracting the arrival of the next mole vole. Since the circular baffle 8 allows the mole vole to freely enter the mousetrap 1, the mole vole's vigilance against previous mousetraps is reduced, and when the mole vole enters the mousetrap 1, the circular baffle 8 closes automatically under the action of gravity and the elastic reset structure 10, making it impossible for the mole vole to escape. There is no need for staff to pick up and readjust the mousetrap in time, which reduces the need for human intervention, helps to reduce working time and labor costs, and improves mouse catching efficiency, reducing the damage of mole voles to crops.
