[0036] Referring to Figures 3-5The first partition plate 17 and the second partition plate 18 are connected with a communication assembly 19, the communication assembly 19 comprises a climbing frame 1901 and a communication hole 1902 arranged on the first partition plate 17, the climbing frame 1901 is connected between the first partition plate 17 and the second partition plate 18, the communication hole 1902 is located at the upper end of the climbing frame 1901, and the climbing frame 1901 is arranged in an inclined manner, the mouse entering the trapping box 10 through the trapping hole 12 can pass through the communication hole 1902 along the climbing frame 1901 and climb onto the first partition plate 17.
[0037] With reference to Figures 5-6 The upper portion of the trapping box 10 is fixedly connected with an alarm device 21, the alarm device 21 can be an alarm lamp or an audible and visual alarm, and the bottom of the collecting barrel 13 is provided with a triggering mechanism 22 connected with the alarm device 21.
[0038] The triggering mechanism 22 comprises a pressing plate 2201 and a triggering switch 2202, the triggering switch 2202 can be a pressure touch switch, the triggering switch 2202 is electrically connected with the alarm device 21 and is fixedly connected to the inner bottom wall of the collecting barrel 13, the pressing plate 2201 is located above the triggering switch 2202 and is slidingly connected in the collecting barrel 13, and the pressing plate 2201 is connected with the collecting barrel 13 through a spring 2203.
[0039] The trapping box 10 is also provided with a battery (not shown in the figure), which is electrically connected with the alarm device 21 and the triggering switch 2202 through wires, and supplies power for the alarm device 21.
[0040] When the mouse falls into the collecting barrel 13, the pressing plate 2201 is pressed downward, thereby extruding and triggering the triggering switch 2202, and the triggering switch 2202 controls the alarm device 21 to alarm.
[0041] The inner surface of the trapping box 10 is rotatably connected with a first baffle 1101 at the upper end of the trapping channel 11, the inner surface of the trapping box 10 is rotatably connected with a second baffle 1201 at the trapping hole 12, and the upper surface of the first partition plate 17 is rotatably connected with a third baffle 1903 at the communication hole 1902.
[0042] When the mouse enters the trapping box 10 from the outside through the trapping hole 12, the second baffle 1201 is flipped, and after the mouse enters the trapping box 10, the second baffle 1201 is turned back under the action of gravity and abuts against the inner surface of the trapping box 10, thereby preventing the mouse from running out of the trapping box 10, and the first baffle 1101 can also prevent the mouse entering the trapping box 10 through the trapping channel 11 from running out, and the third baffle 1903 can also prevent the mouse climbing onto the first partition plate 17 through the communication hole 1902 from returning to the second partition plate 18.
[0043] With reference to Figures 4-5 When the mouse climbs onto the first partition 17 through the communication hole 1902, the third baffle 1903 will be pushed upward to flip, and the third baffle 1903 is located below the second baffle 1201, the second baffle 1201 can block and limit the rotation of the third baffle 1903, prevent the rotation angle of the third baffle 1903 from exceeding ninety degrees, so as to ensure that the third baffle 1903 can rotate back to the original position under the action of gravity after the mouse leaves.
[0044] Moreover, the height of the second baffle 1201 is less than the height of the trapping hole 12, the height of the first baffle 1101 is also less than the height of the trapping channel 11, and the length of the third baffle 1903 is also less than the length of the communication hole 1902, so that the trapping hole 12, the trapping channel 11 and the communication hole 1902 still have a certain gap, which can ensure that the trapping box 10 still communicates with the outside, and ensure that the smell of the trapping food 15 spreads outward to attract the mouse, but due to the small gap, the mouse can also be prevented from climbing outwards through the gap.
[0045] Moreover, the first baffle 1101, the second baffle 1201 and the third baffle 1903 are all transparent materials.
[0046] With reference to Figure 1 With 7 The outer part of the collection barrel 13 is fixedly connected with a sealing plate 16 between the upper and lower cables 3, which is used for sealing the gap between the adjacent cables 3 on the upper and lower layers, blocking the climbing channel of the mouse, and inducing the mouse to climb into the trapping box 10 to a certain extent.
[0047] With reference to Figures 1-2 The trapping channel 11 is inclined and fixedly connected and communicated with the trapping box 10 at the upper end, and is a horn-shaped opening at the lower end and located at the inner bottom wall of the cable trench 1, and the number of the trapping channels 11 is two and symmetrically distributed on both sides of the trapping box 10, so that the mouse climbing at the bottom of the cable trench 1 can enter the trapping channel 11 through the horn-shaped lower end opening of the trapping channel 11 and climb into the trapping box 10 along the trapping channel 11.
[0048] The upper part of the collection barrel 13 is connected with a handle 1301, which is convenient for lifting the collection barrel 13 upward.
[0049] In the utility model, with reference to the drawings Figure 7 With 8, the trap box 10 is located in the cable trench 1, and a cover plate 4 with a transparent observation window 5 is provided on the top of the trap box 10, so that the staff can conveniently observe the inside of the trap box 10 and the alarm device 21. Moreover, the trap box 10 is located in the middle of the two sides of the cable 3, so as to block the mice crawling along the bottom of the cable trench 1. Since the mice have the characteristics of drilling holes, and are guided by the smell of the bait 15, the mice blocked by the way will enter the trap channel 11 with a high probability, and then the first baffle 1101 will be pushed open to enter the first partition plate 17 in the trap box 10, and then the first baffle 1101 will be flipped to the original position under the action of gravity and will block the way back. Then the mouse will be attracted by the bait 15 and climb onto the flap 14, and at this time the flap 14 will be flipped and overturned under the tread of the mouse, and the mouse will fall into the collection barrel 13. Since the inside of the collection barrel 13 has a certain depth and the inner wall is smooth, the mouse falling into the collection barrel 13 can avoid climbing outwards. And the flipped flap 14 will be flipped back to the horizontal state under the action of the balance force.
[0050] And the mouse crawling on the cable 3 will be blocked by the sealing plate 16, and for the same reason, the mouse will drill into the nearby trap hole 12 under the guidance of the bait 15 with a high probability, and then the second baffle 1201 will be pushed open to enter the trap box 10, and then the second baffle 1201 will be flipped back to the original position and will block the trap hole 12 again to prevent the mouse from climbing out. The mouse climbing onto the first partition plate 17 through the trap hole 12 will still be attracted by the bait 15 and climb onto the flap 14, and for the same reason, the flap 14 will be flipped and overturned, and the mouse will fall into the collection barrel 13. The mouse climbing onto the second partition plate 18 through the trap hole 12 will continue to climb upwards through the climbing frame 1901 under the guidance of the smell of the bait 15, and will pass through the communication hole 1902 to the first partition plate 17. In this process, the mouse will push the third baffle 1903 upwards to a certain angle, and after leaving, the third baffle 1903 will be flipped back to the upper surface of the first partition plate 17 under the action of gravity and will block the communication hole 1902 to prevent the mouse from returning. Then the mouse will still be attracted by the bait 15 and will climb onto the flap 14 and fall into the collection barrel 13, and finally the purpose of trapping and retaining the mouse is achieved. Moreover, the trap channel 11 and the trap hole 12 can trap the mouse in all directions, so that the trapping capacity is greatly improved, and the mouse is effectively prevented from running around in the cable trench 1 and gnawing the cable 3, thereby improving the protection ability of the cable 3 to a certain extent.
[0051] Moreover, the mouse falling into the collection barrel 13 will press the pressing plate 2201 to slide and will squeeze the spring 2203 to a certain extent, so as to squeeze and trigger the trigger switch 2202. At this time, the trigger switch 2202 can control the alarm device 21 to alarm, and the staff can timely come to handle after discovering the alarm of the alarm device 21 through the transparent observation window 5 on the cover plate 4.
[0052] When the rats in the collecting barrel 13 need to be disposed, the upper cover plate 4 is first opened, then the collecting barrel 13 is directly lifted up through the handle 1301, the rats are taken out and disposed, finally the collecting barrel 13 and the cover plate 4 are put back to the original position, the pressing plate 2201 is slid back to the original position under the rebound force of the spring 2203 and is separated from the trigger switch 2202, at this time the trigger switch 2202 is also disconnected and the alarm device 21 is turned off.
[0053] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
