Description

Technical Field

[0001] This utility model relates to the technical field of rodent poison bait stations, specifically a structure for preventing accidental ingestion of rodent poison bait stations. Background Technology

[0002] A poison bait station, also known as a poison bait box, is a container used to hold rodenticide. Poison bait stations are divided into permanent and disposable types. Permanent bait stations are fixed in one location using a positioning structure and the bait is replaced periodically. Disposable bait stations are placed directly and are suitable for emergency situations or temporary activity areas such as construction sites and short-term activity areas. Permanent bait stations have locking or anti-accidental contact designs to prevent children, pets, or non-target animals from coming into contact with the bait. For example, in the instruction manual (application number CN117958240A), paragraph 0037 states that "the main body is integrated with the ground and walls using concrete, and then long, thin tools such as spoons or bamboo strips are used to put the bait into the trough. In this state, because the trough is higher than the trench, it can ensure the dryness of the bait and also ensure smooth passage in the rat trails." Another example is publication number CN 213939467. The U instruction manual, paragraph 0029, discloses that "the entrance and exit serve as the first barrier against non-target animals, preventing larger non-target animals from entering the bait station. The placement platform, being higher than the baffle, provides a second barrier against non-target animals. Smaller animals can enter the bait station through the entrance and exit, but due to their small size, they cannot reach the placement platform to eat the bait blocks. Using large bait blocks provides a third barrier against non-target animals. Large bait blocks are not conducive to consumption by small birds and poultry, effectively preventing non-target animals from accidentally ingesting the bait."

[0003] The above-mentioned existing technologies are all permanent poison bait stations, which require a fixed connection to the ground to ensure the stability of the main body before they can be realized. However, the most commonly sold products on the market are disposable rodent poison bait stations. Disposable poison bait stations are low in cost, easy to use, and can be placed directly to take effect. The poison bait has a short evaporation period and becomes ineffective after a period of time. However, disposable poison bait stations, especially for large rats such as brown rats, also have obvious drawbacks, namely that the entrance and exit are too large and cannot prevent pets from accidentally ingesting the poison. In particular, small dogs such as Teddy dogs or cats, which are larger than brown rats, can still enter the entrance and exit of disposable poison bait stations and accidentally ingest the poison bait. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a structure for preventing accidental ingestion of rodent bait stations. This structure enables disposable bait stations to prevent accidental ingestion by pets that are slightly larger than house mice, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structure for preventing accidental ingestion of rodent bait, comprising a hollow channel that runs through the front and back for direct placement on the ground, a concave tray containing poison bait installed in the center of the inner side of the channel, and a protective structure for protecting the concave tray when the channel is moved, located below the concave tray and at the bottom of the channel.

[0006] Preferably, the protective structure includes a protective cover located above the concave plate, with the ends of the protective cover aligned with the front and rear openings of the channel. There are gaps between the protective cover and the top and bottom of the inner side of the channel. A spring is installed on the top surface of the protective cover and fixed to the top surface of the inner side of the channel. The spring is in a contracted state when there is a gap between the protective cover and the bottom of the channel. Multiple top rods extending downward to pass through the bottom surface of the channel are fixedly installed at the four corners of the bottom of the protective cover. Multiple insertion holes with inner diameters corresponding to the diameters of the top rods are opened on the bottom surface of the channel. The top of the top rods is connected to a base plate that fits against the bottom surface of the channel and is placed on the ground.

[0007] Preferably, the protective cover is a cube with an open bottom surface and covers the concave plate.

[0008] Preferably, grooves are formed on both sides of any one of the multiple push rods, and a triangular buckle is movably installed inside the groove. The tail end of the triangular buckle is fixedly connected to the tail end inside the groove by a spring. The triangular buckle is an inverted right triangle.

[0009] Preferably, the protective structure also includes sliders installed on both sides of the concave plate. The sliders slide into vertical grooves opened on the inner side of the channel. A screw rod is threaded through and connected to the center of the concave plate. The bottom of the screw rod passes through the bottom surface of the channel and is connected to a pad plate set on the bottom surface of the channel. A gear is fixedly connected to the bottom of the screw rod. A movable block is rotatably connected to the bottom surface of the gear. The movable block slides into a groove opened on the top surface of the pad plate. A rack that meshes with the gear is fixedly installed on the front and rear sides of the upper end of the inner side of the groove. A spring that is fixedly connected to the front and rear walls of the movable block is installed on the front and rear ends of the inner side of the groove.

[0010] Preferably, multiple insertion rods for inserting into the ground are also installed on both sides of the first and last ends of the pad.

[0011] Compared with the prior art, this utility model provides a structure for preventing accidental ingestion of rodent bait stations, which has the following beneficial effects: 1. This utility model has gaps between the upper and lower ends of the channel and the protective cover. The lower gap allows rats to pass through, while cats or small dogs larger than rats cannot put their heads inside. When the channel is actually overturned, the spring at the top of the inner side of the channel will be released from its compressed state. As the spring returns to its original position, it pushes the protective cover downwards. The push rod slides down through the insertion port, and then the triangular buckle pops out and locks onto the bottom of the channel. At this time, the push rod can no longer return to its original position. Correspondingly, as the push rod moves down, the protective cover connected to its top is also driven to cover the concave plate and form a locked state, preventing pets from accidentally ingesting the poison bait. This makes the disposable poison bait station effective in preventing pets slightly larger than house mice from accidentally ingesting the poison bait. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-5A structure for preventing accidental ingestion of rodent bait station includes a hollow channel 1 that runs through the front and back of the station and is placed directly on the ground. A concave tray 101 containing the bait is installed in the center of the inner side of the channel 1. A protective structure is provided below the concave tray 101 and at the bottom of the channel 1 to protect the concave tray 101 when the channel 1 is moved.

[0016] The protective structure includes a protective cover 2 located above the concave plate 101. The first and last ends of the protective cover 2 are aligned with the front and rear openings of the channel 1. There are gaps between the protective cover 2 and the top and bottom of the inner side of the channel 1. A spring is installed on the top surface of the protective cover 2 and fixed to the top surface of the inner side of the channel 1. The spring is in a contracted state when there is a gap between the protective cover 2 and the bottom of the channel 1. Multiple top rods 201 extending downward to pass through the bottom surface of the channel 1 are fixedly installed at the four corners of the bottom of the protective cover 2. Multiple insertion holes with inner diameters corresponding to the diameter of the top rods 201 are opened on the bottom surface of the channel 1. The top of the top rods 201 is connected to a base plate 3 that is in contact with the bottom surface of the channel 1 and placed on the ground.

[0017] Furthermore, the protective cover 2 is a cube with an open bottom surface inside, and the protective cover 2 covers the concave plate 101.

[0018] Channel 1 is made of cement or acrylic, and protective cover 2 is made of PE or PP.

[0019] The top rod 201 is also made of PE or PP material, and there are four top rods 201. The four top rods 201 are heat-fused to the bottom surface of the protective cover 2.

[0020] A groove 202 is provided on both sides of any one of the multiple push rods 201. A triangular buckle 203 is movably installed inside the groove 202. The tail end of the triangular buckle 203 is fixedly connected to the tail end inside the groove 202 by a spring. The triangular buckle 203 is an inverted right triangle.

[0021] The protective structure also includes sliders 4 installed on both sides of the concave plate 101. The sliders 4 slide into the vertical grooves 5 opened inside the channel 1. A screw 6 is threaded through and connected to the center of the concave plate 101. The bottom of the screw 6 passes through the bottom surface of the channel 1 and is connected to a pad 8 set on the bottom surface of the channel 1. A gear 601 is fixedly connected to the bottom of the screw 6. A moving block is rotatably connected to the bottom surface of the gear 601. The moving block slides into the groove 801 opened on the top surface of the pad 8. A rack 802 is fixedly installed on the upper inner side of the groove 801 at both the front and rear sides, and it is engaged with the gear 601.

[0022] The pad 8 also has multiple insertion rods installed on both sides of its ends for inserting into the ground. Please refer to the instruction manual. Figure 6 There are four insertion rods, and the top surface of each insertion rod is flush with the top surface of the pad 8, both being inclined surfaces. Example 1

[0023] In actual rodent control, the passage 1 is placed directly on the ground. Passage 1 is made of cement or acrylic sheet, while the top rod 201 and protective cover 2 are made of PE or PP material. Taking advantage of the fact that the density of passage 1 is greater than that of the top rod 201 and protective cover 2, as per the instruction manual... Figure 1-4 The weight and volume of the channel 1 shown are both greater than that of the protective cover 2. Therefore, when the channel 1 is placed on the ground, its own weight presses down on the top rod 201. At this time, pressing the triangular buckle 203 set on the side wall of any top rod 201 prevents the right-angled side of its inverted bottom from contacting the bottom surface of the channel 1, thereby releasing the triangular buckle 203 from limiting the top rod 201. At this time, the top rod 201 continues to move upward, thereby lifting the protective cover 2 and compressing the spring at that point. The protective cover 2 moves upward from the inner bottom surface of the channel 1, revealing the concave plate 101 below it, and also revealing the rat exterminator placed in the concave plate 101. The poison bait is placed on the channel 1, and the protective cover 2 continues to move upward until the bottom plate 3 at the bottom of the top rod 201 is completely close to the bottom surface of the channel 1. In actual use, mice smelling the poison bait will enter directly through the front and rear openings of the channel 1 and eat the poison bait placed on top of the concave plate 101. After eating, they will exit through the front and rear openings inside the channel 1 without any obstruction. However, if a pet larger than a mouse, such as a poodle or cat, smells the poison bait and tries to enter, the protective cover 2 above the inside of the channel 1 will act as the first line of defense. Please refer to the instruction manual. Figure 1-4 Because there are gaps between the upper and lower ends of the channel 1 and the protective cover 2, the lower gap is for mice to pass through, while cats or small dogs larger than mice cannot put their heads through. Furthermore, to prevent pets from knocking over the channel 1 and obtaining the poison bait, when the channel is actually knocked over, the spring at the top of the inner side of the channel 1 will be released from its compressed state. As the spring rebounds and resets, it pushes the protective cover 2 downward. Since the bottom of the protective cover 2 is connected to the push rod 201, and the push rod 201 slides down through the socket, and the triangular buckle 203 is installed upside down, the front end of the triangular buckle 203 contacts the socket and is compressed, causing the bottom of the right-angled side to be compressed into the groove 202. Then, after the triangular buckle 203 passes through the socket, its internal spring pushes it out of the groove 202. Then the triangular buckle 203 is popped out and stuck on the bottom surface of the channel 1. At this time, the push rod 201 can no longer reset. Correspondingly, as the push rod 201 moves down, the protective cover 2 connected to its top is also moved to cover the concave plate 101, forming a locked state to prevent pets from accidentally ingesting it.

[0024] In use, mice, attracted by the scent of the poisoned bait, will enter directly through the front and rear openings of channel 1 and eat the bait placed on top of the concave plate 101. After eating, they will exit through the front and rear openings inside channel 1 without any obstruction. However, if a pet larger than a mouse, such as a poodle or cat, smells the bait and tries to enter, the protective cover 2 on the upper inside of channel 1 will act as the first barrier. Since there are gaps between the upper and lower ends of channel 1 and the protective cover 2, the lower gap allows mice to pass through, while cats or small dogs larger than mice cannot stick their heads through. Furthermore, to prevent pets from knocking over channel 1 and obtaining the poisoned bait, a spring at the top inside channel 1 will activate if the channel is actually knocked over. Released from compression, the protective cover 2 is pushed downwards as the spring returns to its original position. Since the bottom of the protective cover 2 is connected to the push rod 201, and the push rod 201 slides down through the socket, while the triangular buckle 203 is installed upside down, the front end of the triangular buckle 203 contacts the socket and is compressed, causing the bottom of the right-angled side to also be compressed into the groove 202. After the triangular buckle 203 passes through the socket, its internal spring pushes it out of the groove 202, and then the triangular buckle 203 is popped out and stuck on the bottom surface of the channel 1. At this time, the push rod 201 can no longer be reset, and as the push rod 201 moves down, the protective cover 2 connected to its top is also moved to cover the concave plate 101 to form a locked state, preventing pets from accidentally ingesting it.

[0025] Example 2

[0026] Although the protective cover 2 in Embodiment 1 can lock the concave tray 101 to prevent pets from accidentally ingesting it, in reality, once the protective cover 2 is locked, the entire bait station becomes unusable. Since the cost of installing sensors in the disposable bait station in Embodiment 1 is too high, it can only rely on patrol personnel to discover the bait, which is too passive. Therefore, this embodiment is proposed, and the implementation method of this embodiment is as follows: By creating a groove 801 on the top surface of the pad 8, and slidably connecting the moving block to the inside of the groove 801, the channel 1 of this embodiment can be installed simply by placing it on the ground. Please refer to the appendix of the instruction manual. Figure 6-7In this embodiment, the initial position of the moving block is in the center of the slide 801. The corresponding screw 6, connected to the channel 1 and the concave plate 101, is also located at the center of the top surface of the pad 8. In actual use, when a mouse smells the poison bait, it will directly enter the inner side of the channel 1 through the front and rear openings and eat the poison bait placed on the concave plate 101. After eating, it will still exit through the front and rear openings inside the channel 1 without any obstruction. However, when a pet larger than a mouse, such as a poodle or cat, smells the poison bait and tries to enter, its larger size will cause it to make contact with the channel 1 if it forces its way in. At this time, the channel 1 will be forced to move backward or... When the channel 1 moves forward, it simultaneously drives the concave plate 101 and the screw 6. The bottom of the screw 6 is heat-welded to the gear 601 via a heat-fusion method. The gear 601 is rotatably connected to the moving block, forming an inner and outer ring bearing structure for rotation. In reality, they remain connected. Therefore, when the screw 6 moves horizontally, it inevitably drives the gear 601 and its bottom moving block to move together. Further movement of the moving block inside the groove 801 will cause the gear 601 to contact the rack 802, at which point they mesh. Because the gear 601 rotates relative to the moving block, it begins to drive the screw 6 to rotate. Please refer to the attached instruction manual. Figure 6 Since the screw 6 is threadedly connected to the concave disc 101, the concave disc 101 begins to move relative to the screw 6. Furthermore, the sliders 4 on both sides of the concave disc 101 can only move up and down inside the vertical groove 5, preventing the concave disc 101 from rotating due to the screw 6. At this point, the concave disc 101 converts its circular motion into linear motion and begins to move upwards. After the concave disc 101 moves upwards, the pet's front paws cannot reach the rat poison inside the concave disc 101. Correspondingly, the racks 802 in this application are staggered as shown in the attached instruction manual. Figure 6 As shown, regardless of whether the moving block moves forward or backward from the center of the inner side of the slide groove 801, the screw 6 drives the concave plate 101 to move upward. At the same time, springs are fixedly installed at the front and rear ends of the slide groove 801. The springs are compressed after the moving block moves and reset after the moving block loses its thrust, thereby resetting the concave plate 101.

[0027] Furthermore, this embodiment also installs a plug on the bottom surface of the pad 8. During actual installation, the pad 8 is placed on the ground and the plug is driven into the ground by a claw hammer or flathead hammer for simple fixation. This ensures that the pad 8 will not tip over due to impact from a large pet dog during actual use.

[0028] When in use, if a pet larger than a mouse, such as a Teddy dog ​​or cat, smells the poisoned bait and tries to enter, its larger size will cause it to force its way into channel 1, making contact with it. At this point, channel 1 will be under pressure and begin to move backward or forward. This movement of channel 1 will simultaneously drive the concave plate 101 and the screw 6. The bottom of the screw 6 is heat-fused to a gear 601, which is rotatably connected to the moving block. The two form an inner and outer ring bearing structure for rotation. In reality, they remain connected. Therefore, when the screw 6 moves horizontally, it will inevitably drive the gear 601 and its bottom moving block to move together. Further movement of the moving block inside the groove 801 will cause the gear 601 to contact the rack 802, forming a mesh. Because the gear 601 rotates relative to the moving block, it will then drive the screw 6 to rotate. Please refer to the instruction manual appendix. Figure 6 Since the screw 6 is threadedly connected to the concave disc 101, the concave disc 101 begins to move relative to the screw 6. Furthermore, the sliders 4 on both sides of the concave disc 101 can only move up and down inside the vertical groove 5, preventing the concave disc 101 from rotating due to the screw 6. At this point, the concave disc 101 converts its circular motion into linear motion and begins to move upwards. After the concave disc 101 moves upwards, the pet's front paws cannot reach the rat poison inside the concave disc 101. Correspondingly, the racks 802 in this application are staggered as shown in the attached instruction manual. Figure 6 As shown, regardless of whether the moving block moves forward or backward from the center of the inner side of the slide groove 801, the screw 6 drives the concave plate 101 to move upward. At the same time, springs are fixedly installed at the front and rear ends of the slide groove 801. The springs are compressed after the moving block moves and reset after the moving block loses its thrust, thereby resetting the concave plate 101.
