Abstract
Description
Technical Field
[0001] This utility model relates to the field of rat-catching technology, specifically a cage-type rat trap. Background Technology
[0002] Rats are one of the four pests. They are resilient, numerous, and reproduce rapidly. They are highly adaptable, eat almost anything, and can live almost anywhere. They can spread diseases such as plague, hemorrhagic fever, and leptospirosis, causing great trouble to people's lives. Currently, there are many kinds of rat-catching tools on the market, such as rat traps or rat cages, but these rat traps often only catch one rat, making them inefficient.
[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art:
[0004] While existing cage-style mousetraps can catch multiple mice, most of the current traps are rocker traps. However, when a mouse is caught inside the cage by one end of the rocker falling down, another mouse inside the cage may escape by the other end of the rocker falling down.
[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a cage-type mousetrap that solves the problem that when a rocker trap is used to catch mice, the trapped mouse may escape from the falling rocker.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A cage-type mousetrap includes a cage-type mousetrap with a mouse-catching inlet on one side of its front end. A mouse-catching frame is fixedly installed inside the mouse-catching inlet. A baffle is rotatably installed at the bottom of the front end of the mouse-catching inlet, and a tension plate is movably installed at the bottom of the baffle. A rotating plate is rotatably installed at the bottom inside the mouse-catching frame. Cavities are formed on both sides of the rear end of the mouse-catching frame. A rotating rod, fixedly connected to the rotating plate, is rotatably installed inside the cavity. A torsion spring, fixedly connected to the inner wall of the cavity, is sleeved and fixedly installed on the outer side of the rotating rod.
[0009] Preferably, the bottom of the baffle is provided with grooves on both sides, and a slider that is fixedly connected to the top of the tension plate is slidably installed inside the groove.
[0010] Preferably, a support rod is fixedly installed at the rear end of the top of the mouse trap frame, and a first pull rope extending into the inside of the mouse trap frame is sleeved on the outside of the support rod, with a ball cage provided at the bottom of the first pull rope.
[0011] Preferably, the bottom of the cage trap is provided with an outlet, and fixed rods are fixedly installed on both sides of the outlet. A collar is sleeved on the outside of the fixed rod, and a sealing door is fixedly installed at the front end of the collar.
[0012] Preferably, a limit bolt is movably installed on one side of the front end of the cage rat trap, and a limit ring extending into the interior from the other end of the limit bolt is fixedly installed on one side of the bottom of the tension plate.
[0013] Preferably, a pull rod is fixedly installed on the top of the front end of the sealed door, a second pull rope is movably installed on the top of the other side of the cage mousetrap, and a barb is provided at the bottom of the second pull rope. A handle is rotatably installed on the top of the cage mousetrap.
[0014] Compared with the prior art, this utility model provides a cage-type mousetrap with the following advantages: This utility model extends from a high place to the ground through a baffle and a tension plate. When a mouse smells the aroma of food inside the cage, it climbs through the baffle and tension plate into the mousetrap frame. The mouse steps on the rotating plate, which rotates and opens under the action of gravity. At this time, the mouse falls into the cage-type mousetrap and is captured. Under the action of the torsion spring, the rotating plate returns to its original position. Since the mousetrap frame is in a closed state, the mouse cannot escape after being captured, avoiding the situation where the captured mouse may escape from the falling rocker of the rocker when one end of the rocker falls, as is the case with current rocker traps.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a cage-type mousetrap.
[0024] Please see Figures 1-6 A cage-type mousetrap includes a cage mousetrap 1, with a mouse-catching inlet 101 on one side of the front end of the cage mousetrap 1. A mouse-catching frame 102 is fixedly installed inside the mouse-catching inlet 101. A baffle 103 is rotatably installed at the bottom of the front end of the mouse-catching inlet 101, and a tension plate 104 is movably installed at the bottom of the baffle 103. A rotating plate 105 is rotatably installed at the bottom inside the mouse-catching frame 102. Cavities 106 are opened on both sides of the rear end of the mouse-catching frame 102, and a device fixed to the rotating plate 105 is rotatably installed inside the cavity 106. A rotating rod 107 is fixedly connected, and a torsion spring 108 fixedly connected to the inner wall of the cavity 106 is sleeved and fixedly installed on the outer side of the rotating rod 107. Slide grooves 109 are opened on both sides of the bottom of the baffle 103. A slider 110 fixedly connected to the top of the tension plate 104 is slidably installed inside the slide grooves 109. A support rod 111 is fixedly installed at the rear end of the top of the mouse trap frame 102. A first pull rope 2 extending into the inside of the mouse trap frame 102 is sleeved and installed on the outer side of the support rod 111. A ball cage 201 is provided at the bottom of the first pull rope 2.
[0025] With the above-described structure, this cage-type mousetrap first pulls the extension plate 104, causing the slider 110 to slide inside the slide groove 109, which in turn unfolds the baffle 103 and the extension plate 104, extending them from a high place to the ground. Then, mouse food is placed inside the ball cage 201 and closed. The ball cage 201 is suspended inside the mouse trap frame 102 by the first pull rope 2 tied to the top of the ball cage 201 to lure mice. When a mouse climbs through the baffle 103 and the extension plate 104 to the inside of the mouse trap frame 102 and stands on the top of the rotating plate 105, the rotating plate 105 automatically flips downward and opens under the action of gravity, causing the mouse to fall into the cage-type mousetrap 1 and be captured. Then, under the torque of the torsion spring 108, the rotating plate 105 automatically flips upward and closes, preventing the mouse from escaping. This solves the problem that when a rocker trap catches mice, the captured mouse may escape from the falling rocker when one end of the rocker falls.
[0026] Furthermore, the bottom of the cage-like mousetrap 1 is provided with an outlet 112. Fixed rods 3 are fixedly installed on both sides of the outlet 112. A collar 301 is sleeved on the outer side of the fixed rods 3, and a sealing door 302 is fixedly installed at the front end of the collar 301. When staff need to remove and process the captured mouse, the collar 301 slides upwards on the outer side of the fixed rods 3, causing the sealing door 302 to move upwards, thereby opening the outlet 112 and allowing staff to easily remove and process the captured mouse through the outlet 112.
[0027] Furthermore, a limiting bolt 4 is movably installed on one side of the front end of the cage mousetrap 1, and a limiting ring 401 extending into the interior of the other end of the limiting bolt 4 is fixedly installed on one side of the bottom of the stretch plate 104. When the baffle 103 and the stretch plate 104 are folded and retracted, they are processed to flip upwards to close the mousetrap entrance 101. Then, the other end of the limiting bolt 4 is slid into the limiting ring 401 for limiting and fixing, thereby closing and fixing the opening of the mousetrap entrance 101, making it convenient to carry the cage mousetrap 1.
[0028] Furthermore, a pull rod 303 is fixedly installed on the top of the front end of the sealed door 302, and a second pull rope 304 is movably installed on the top of the other side of the cage mousetrap 1. The bottom of the second pull rope 304 is provided with a barb, and a handle 5 is rotatably installed on the top of the cage mousetrap 1. The operator can easily pull the sealed door 302 using the pull rod 303. When the sealed door 302 is pulled up, it is hooked onto the outside of the pull rod 303 by the barb at the bottom of the second pull rope 304, thus fixing the sealed door 302 to the top of the outlet 112 for easy removal of the mouse. By holding the handle 5, the cage mousetrap 1 can be easily lifted and carried to any location.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
