Technical Field
[0001] This utility model relates to the field of rodent control technology, and in particular to an outdoor rainproof rodent bait station. Background Technology
[0002] A rodent bait station is a specialized device used to deliver rodent bait. It attracts rats to eat the bait in a safe and discreet manner, while reducing environmental harm. It is usually made of corrosion-resistant and bite-resistant materials, which can effectively improve rodent control efficiency and reduce safety risks.
[0003] When using rodent bait stations, the bait box containing the poison bait needs to be placed inside a ceramic tube, and then the ceramic tube should be placed in a place where rats are likely to pass through, in order to kill the rats. However, in order to facilitate the rats to enter the ceramic tube, both ends of the ceramic tube are open. When it rains, rainwater can easily enter the bait box from both ends of the ceramic tube under the action of the wind, which will wet and dilute and contaminate the poison bait. This will reduce the effectiveness of the poison bait and may also pollute the environment around the bait station. Utility Model Content
[0004] This invention addresses the problem that rainwater can easily enter the bait box from both ends of the ceramic tube under the influence of wind, thus wetting, diluting, and contaminating the bait. This can reduce the effectiveness of the bait and may also pollute the environment around the bait station. Therefore, this invention proposes an outdoor rainproof rodent bait station.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor rainproof rodent bait station, comprising a ceramic cylinder, characterized in that: the vertical cross-section of the ceramic cylinder is a quarter circle shape, a bait box is provided at the bottom of the inner wall of the ceramic cylinder, a rainproof device is provided between the bait box and the ceramic cylinder, and the rainproof device blocks the bait box from both sides by setting two baffles respectively.
[0006] The effect achieved by the above components is as follows: by setting two baffles and adjusting their positions, and placing the bait box between the two baffles with the baffles higher than the sides of the bait box, the two baffles can block the top of the sides of the bait box respectively. This helps to prevent rainwater from entering the bait box from both ends of the ceramic tube under the action of wind, thus preventing the bait from getting wet and contaminated. In turn, it helps to prevent the bait's potency from decreasing and prevent the bait from falling out of the ceramic tube and causing pollution around the bait station.
[0007] Preferably, the rainproof device includes a rectangular frame, which is fixedly installed at the bottom of the inner wall of the ceramic cylinder. The poison bait box is disposed inside the rectangular frame. Two baffles are slidably installed inside the rectangular frame. The poison bait box is disposed between the two baffles. The height of the baffles is higher than the height of the poison bait box. An auxiliary groove is provided at the bottom of the inner wall of the ceramic cylinder. One end of the baffle is slidably installed on the inner wall of the auxiliary groove.
[0008] The effect achieved by the above components is as follows: by setting two baffles, since the height of the baffles is higher than the height of the poison bait box, the two baffles are pushed and the poison bait box is placed between the two baffles. Since the height of the baffles is higher than the height of the poison bait box, the two baffles can block the sides of the poison bait box, which helps to prevent rainwater from entering the poison bait box from both ends of the ceramic tube under the action of wind.
[0009] Preferably, the tops of both sides of the inner wall of the auxiliary groove are inclined surfaces.
[0010] The effect achieved by the above-mentioned components is that by setting auxiliary channels with sloping tops on both sides, rainwater in the rectangular frame can be quickly discharged through the auxiliary channels.
[0011] Preferably, the same spring is fixedly installed on the side of the two baffles that are close to each other, and the spring is disposed inside the auxiliary groove.
[0012] The effect achieved by the above components is as follows: by setting up a spring, when the spring is not subjected to other external forces, the spring will stretch the two baffles, thereby bringing the two baffles closer together. Then, pushing the two baffles apart will push them away from each other, and the baffles will compress the spring, causing the spring to deform until the two baffles reach the appropriate position. Then, the poison bait box is placed between the two baffles, and the force applied to the baffles is removed. The spring will then reset and drive the baffles to move until the two baffles completely clamp the poison bait box. Thus, the two baffles can both shield the poison bait box and limit its position, which helps to prevent the poison bait box from floating inside the ceramic cylinder under the action of rainwater, and also prevents the poison bait box from falling out of the ceramic cylinder under the influence of wind and the activity of rats.
[0013] Preferably, the spring has a round rod inside, with both ends of the round rod fixedly installed on the inner wall of the auxiliary groove, and both baffles are slidably installed on the outer surface of the round rod.
[0014] The effect achieved by the above components is that by setting the round rod, the round rod can limit and guide the spring, which helps to prevent the spring from easily bending during deformation.
[0015] Preferably, a rubber plate is fixedly installed on the side of each of the two baffles that are close to each other.
[0016] The effect achieved by the above-mentioned components is as follows: by setting a rubber plate to replace the baffle and abut against the side of the poison bait box, the baffle can play a certain protective role when limiting the poison bait box, and at the same time, it can increase the friction between the baffle and the poison bait box, making the baffle more firmly fixed to the poison bait box.
[0017] Preferably, pins are fixedly installed on the opposite sides of the two baffles, and slot blocks are symmetrically fixedly installed on both sides of the top of the rectangular frame. The size and shape of the outer surface of the pins are adapted to the size and shape of the inner wall of the slot blocks.
[0018] The effect achieved by the above components is as follows: by pushing the two baffles apart until the pins on one side of the baffles are fully inserted into the inner wall of the slot block, the two baffles can be fixed, thus making it easier to place the poison bait box in the rectangular frame.
[0019] Preferably, a rubber block is fixedly installed at one end of the pin, and the cross-section of the rubber block in the vertical direction is an isosceles trapezoid.
[0020] The effect achieved by the above-mentioned components is as follows: by setting an isosceles trapezoidal rubber block, one end of the rubber block is smaller, which makes it easier to insert into the inner wall of the slot block, while the other end of the rubber block is larger, which can limit the movement between the pin and the slot block, thus helping to prevent the pin from falling out of the slot block.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0022] In this invention, by setting two baffles and adjusting their positions, and placing the bait box between the two baffles with the baffles higher than the sides of the bait box, the two baffles can block the top of the sides of the bait box, which helps to prevent rainwater from entering the bait box from both ends of the ceramic tube under the action of wind, thus preventing the bait from getting wet and contaminated. This also helps to prevent the bait's potency from decreasing and prevent the bait from falling out of the ceramic tube and causing pollution around the bait station. Attached Figure Description

[0028] Example 1, referring to Figures 1-4 As shown, this embodiment discloses an outdoor rainproof rodent bait station, including a ceramic cylinder 1. The cross-section of the ceramic cylinder 1 in the vertical direction is a quarter circle. A bait box 2 is provided at the bottom of the inner wall of the ceramic cylinder 1. A rainproof device 3 is provided between the bait box 2 and the ceramic cylinder 1. The rainproof device 3 uses two baffles 32 to block the sides of the bait box 2 respectively. By setting the two baffles 32 and adjusting the position of the baffles 32, the bait box 2 is placed between the two baffles 32. The height of the baffles 32 is higher than the height of the sides of the bait box 2. Then the two baffles 32 can block the top of the sides of the bait box 2 respectively. This helps to prevent rainwater from entering the bait box 2 from both ends of the ceramic cylinder 1 under the action of wind, which would cause the bait to get wet and contaminated. This also helps to prevent the poison of the bait from decreasing and prevent the bait from falling out of the ceramic cylinder 1 and causing pollution to the area around the bait station.
[0029] Reference Figure 3 and Figure 4 As shown, the rainproof device 3 includes a rectangular frame 31, which is fixedly installed at the bottom of the inner wall of the ceramic cylinder 1. The poison bait box 2 is located inside the rectangular frame 31. Two baffles 32 are slidably installed inside the rectangular frame 31, and the poison bait box 2 is located between the two baffles 32. The height of the baffles 32 is higher than the height of the poison bait box 2. An auxiliary groove 33 is provided at the bottom of the inner wall of the ceramic cylinder 1. One end of the baffle 32 is slidably installed on the inner wall of the auxiliary groove 33. By setting two baffles 32, since the height of the baffles 32 is higher than the height of the poison bait box 2, the two baffles 32 are pushed and the poison bait box 2 is placed between the two baffles 32. Since the height of the baffles 32 is higher than the height of the poison bait box 2, the two baffles 32 can block the two sides of the poison bait box 2, which helps to prevent rainwater from entering the poison bait box 2 from both ends of the ceramic cylinder 1 under the action of wind. The top of both sides of the inner wall of the auxiliary groove 33 is inclined. By setting the auxiliary groove 33 with inclined tops on both sides, it is easy to quickly discharge the rainwater in the rectangular frame 31 through the auxiliary groove 33.
[0030] Reference Figure 3 and Figure 4As shown, a spring 34 is fixedly installed on the side of the two baffles 32 that are close to each other. The spring 34 is located inside the auxiliary groove 33. By setting the spring 34, when there is no other external force, the spring 34 will stretch the two baffles 32, causing the two baffles 32 to move closer to each other. Then, it will push the two baffles 32 away from each other, causing the baffles 32 to compress the spring 34, causing the spring 34 to deform until the two baffles 32 reach the appropriate position. Then, the poison bait box 2 is placed between the two baffles 32, and the force applied to the baffles 32 is removed. The spring 34 will then return to its original position and drive the baffles 32 to move until the two baffles 32 reach the appropriate position. The baffles 32 completely clamp the poison bait box 2, thus blocking and limiting the poison bait box 2. This helps prevent the poison bait box 2 from floating inside the ceramic cylinder 1 under the action of rainwater, and also prevents the poison bait box 2 from detaching from the ceramic cylinder 1 under the influence of wind and rodent activity. The spring 34 is equipped with a round rod 35 inside, with both ends of the round rod 35 fixedly installed on the inner wall of the auxiliary groove 33. Both baffles 32 are slidably installed on the outer surface of the round rod 35. By setting the round rod 35, the round rod 35 can limit and guide the spring 34, which helps prevent the spring 34 from easily bending during deformation.
[0031] Reference Figure 3 and Figure 4 As shown, rubber plates 36 are fixedly installed on the side of the two baffles 32 that are close to each other. By setting the rubber plates 36, one side of the baffle 32 abuts against one side of the poison bait box 2. This can play a certain protective role for the poison bait box 2 when the baffle 32 limits the poison bait box 2. At the same time, it can increase the friction between the baffle 32 and the poison bait box 2, making the baffle 32 more firmly fixed to the poison bait box 2.
[0032] Reference Figure 3 and Figure 4 As shown, pins 37 are fixedly installed on the opposite sides of the two baffles 32. Slot blocks 38 are symmetrically fixedly installed on both sides of the top of the rectangular frame 31. The size and shape of the outer surface of the pins 37 are adapted to the size and shape of the inner wall of the slot blocks 38. Pushing the two baffles 32 causes them to move away from each other until the pins 37 on one side of the baffles 32 are fully inserted into the inner wall of the slot blocks 38, thus fixing the two baffles 32 and facilitating the placement of the poison bait box 2 in the rectangular frame 31. A rubber block 39 is fixedly installed at one end of the pin 37. The vertical cross-section of the rubber block 39 is an isosceles trapezoid. By setting the rubber block 39 to be isosceles trapezoidal, one end of the rubber block 39 is smaller, making it easier to insert into the inner wall of the slot blocks 38. At the same time, the other end of the rubber block 39 is larger, which can limit the movement between the pin 37 and the slot blocks 38, helping to prevent the pin 37 from detaching from the slot blocks 38.
[0033] Working principle: Pushing the two baffles 32 away from each other causes them to compress the spring 34, deforming it until the rubber block 39 and pin 37 on one side of the two baffles 32 insert into the inner wall of the slot block 38, thus fixing the two baffles 32 in place. Then, placing the poison bait box 2 between the two baffles 32 and pulling the baffles 32 causes the rubber block 39 and pin 37 to disengage from the inner wall of the slot block 38. This causes the spring 34 to reset and move the baffles 32. The bait box 2 is moved until the rubber plate 36 on one side of the two baffles 32 completely clamps it. The two baffles 32 can shield the bait box 2 and limit its position. This helps to prevent the bait box 2 from floating inside the ceramic cylinder 1 under the action of rainwater. It also prevents the bait box 2 from falling out of the ceramic cylinder 1 under the influence of wind and the activity of rats. In addition, the two baffles 32 can block the two sides of the bait box 2, which helps to prevent rainwater from entering the bait box 2 from both ends of the ceramic cylinder 1 under the action of wind.
