Description

Technical Field

[0001] This utility model relates to the field of insect trapping structure technology, and in particular to an insect trapping structure that prevents escape. Background Technology

[0002] The customs system bears a crucial responsibility in safeguarding national biosecurity. At airport ports, customs officers, clad in specialized protective gear and armed with sophisticated insect-catching tools, traverse various facilities around the tarmac and in hidden corners of the terminal building. At docks where merchant ships are present, staff board the vessels and venture inside individual shipping containers. These containers, having endured long sea voyages, possess complex internal environments, providing ideal hiding and breeding grounds for disease-carrying organisms such as cockroaches, mosquitoes, and flies. Customs officers utilize specialized trapping devices, leveraging the phototaxis and chemotaxis of these vectors, to precisely lure and capture them from their hiding places. Because these vectors may carry numerous pathogens, their introduction into the country could potentially trigger the spread of infectious diseases, seriously threatening public health and the stability of the ecological environment. Therefore, this aspect of the customs system's work plays a vital role in protecting the nation's biosecurity defenses.

[0003] Capturing pests such as cockroaches, mosquitoes, and flies is crucial. These pests, as disease vectors, are often carriers of numerous pathogens. For example, mosquitoes can transmit deadly diseases like malaria and dengue fever, while cockroaches carry bacteria and viruses that can contaminate food and cause intestinal diseases. Once they enter the country with cargo or merchant ship containers at airports, they can easily multiply and spread pathogens in the new environment, posing a serious threat to public health and ecological balance. Customs officials employ various professional methods to capture pests at airports and inside merchant ship containers. Utilizing the phototaxis of pests, ultraviolet lamps are deployed at night; attracted by the light, pests are either electrocuted by an electric grid or stuck to special adhesive paper. Targeting the chemotaxis of pests, traps containing special scented baits are used; for example, sweet-smelling baits are used for cockroaches, and putrid-smelling baits for flies, capturing them when they approach to feed. Simultaneously, staff also conduct manual patrols, carefully inspecting all hidden corners to ensure comprehensive pest capture and safeguard national biosecurity.

[0004] However, some existing insect-trapping structures are ineffective in preventing pests from escaping. Some sticky traps lack sufficient adhesiveness, allowing some pests to break free during their struggles and return to the environment to continue causing harm. Chemical traps suffer from poorly designed openings; once lured in, pests can easily escape when stimulated due to overly large openings or a lack of effective blocking mechanisms. Furthermore, some mechanical insect cages have improperly spaced grids, allowing smaller pests to easily pass through, rendering the initial trapping efforts futile. This significantly impacts the effectiveness of insect trapping and the overall success of pest control. Therefore, to address these shortcomings, an escape-prevention insect-trapping structure is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an escape-prevention insect-trapping structure, which aims to improve the problem that existing insect-trapping structures cannot effectively prevent pests from escaping.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An escape-proof insect trapping structure includes an outer shell and a base plate. A ventilation net is fixedly connected to the top of the outer shell. Multiple conical frames are fixedly connected inside the outer shell. Multiple arc-shaped plates are fixedly connected inside each of the conical frames. Triangular plates are movably connected to the side of each arc-shaped plate closest to the axis of the conical frame. A fixing block is fixedly connected to the side of each arc-shaped plate closest to the central axis of the outer shell. Semi-circular wheels are fixedly connected to the side of each arc-shaped plate closest to the central axis of the outer shell. Elastic connecting ropes are sleeved on the outside of each semi-circular wheel. A collection frame is fixedly connected to the top of the base plate. A support rod is fixedly connected to the top of the collection frame. A trapping disc is fixedly connected to the top of the support rod. An electric grid frame is fixedly connected to the outside of the support rod. A power supply is installed inside the collection frame. A splicing assembly for assembly is provided on the top of the base plate.

[0008] As a further description of the above technical solution:

[0009] The splicing assembly includes multiple locking blocks, the bottom of which is fixedly connected to the top of the base plate. Each locking block has a locking groove inside. Multiple docking frames are fixedly connected to the outside of the outer shell. Each docking frame has a sliding ring slidably connected inside. Each sliding ring has a limit rod fixedly connected inside. Each docking frame has a limit groove inside. Each sliding ring has a locking post fixedly connected inside. Each locking post has a spring sleeved on its outside. Each locking post has a pull plate fixedly connected to the opposite side of its opposite side.

[0010] As a further description of the above technical solution:

[0011] One end of the connecting elastic rope is fixedly connected to the outside of the fixed block, and the other end of the connecting elastic rope is fixedly connected to the outside of the triangular plate.

[0012] As a further description of the above technical solution:

[0013] The outer surface of the collection frame is slidably connected to the inside of the outer casing, and the top of the base plate is in contact with the bottom of the outer casing;

[0014] As a further description of the above technical solution:

[0015] The output terminal of the power supply is electrically connected to the bottom of the grid frame via a wire, and the outer side of the card block is slidably connected to the inside of the docking frame;

[0016] As a further description of the above technical solution:

[0017] The external part of the card post is slidably connected to the inside of the card slot, and both the card block and one end of the card post are designed with inclined surfaces;

[0018] As a further description of the above technical solution:

[0019] The limiting rod is externally slidably connected to the inside of the limiting groove, and the sliding ring is externally slidably connected to the inside of the docking frame;

[0020] As a further description of the above technical solution:

[0021] One end of the spring is fixedly connected to the outside of the sliding ring, and the other end of the spring is fixedly connected to the outside of the pull plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, when pests are attracted by the trapping tray and enter the outer shell through the conical frame, they can push open the triangular plate and enter smoothly. When the pests attempt to escape, the protrusion on the semi-circular wheel tightly engages the connecting elastic rope. The elasticity of the connecting elastic rope restricts the triangular plate from rotating inwards into the conical frame, successfully preventing the pests from escaping through the entrance, significantly improving the efficiency and effectiveness of pest trapping, and providing secondary protection with the electric grid. After the pests enter the outer shell, the power supply activates the fine electric grid on the surface of the frame, killing the pests. Simultaneously, the conical design of the electric grid frame works in conjunction with the conical frame, causing the electrocuted pests to fall along the conical surface into the collection frame, further eliminating the possibility of pests escaping inside the outer shell.

[0024] 2. In this utility model, during assembly, simply align the inclined surface of the top locking block of the base plate with the bottom of the outer casing's mating frame and push it upwards. As the locking block inserts into the mating frame, its inclined surface pushes the locking post, causing the sliding ring to shift and compress the spring. Once the locking post aligns with the slot, the spring returns, and the locking post inserts into the slot, completing the assembly. No complex tools or professional skills are required; the operation is simple, greatly improving assembly efficiency and facilitating user installation and maintenance. It not only facilitates transportation and storage but also allows for individual replacement of damaged components, reducing maintenance costs and difficulty, further highlighting its ease of assembly.

[0033] 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.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of an escape-prevention insect-trapping structure, comprising an outer shell 1 and a base plate 9, with the outer shell 1 serving as the main frame of the entire insect-trapping structure. The top of the base plate 9 contacts the bottom of the outer shell 1. A ventilation net 2 is fixedly connected to the top of the outer shell 1. The ventilation net 2 is made of a fine mesh material, with carefully designed mesh sizes to ensure free airflow, allowing the scent emitted by the trap 12 to diffuse smoothly and attract pests, while preventing large objects such as birds and leaves from entering the interior of the outer shell 1, thus avoiding affecting the insect-trapping effect and causing damage to the internal structure. Multiple conical frames 3 are fixedly connected inside the outer shell 1. The conical design of the frames 3, with the open end facing outwards and the gradually narrowing end facing inwards, guides pests towards the interior of the outer shell 1. When pests are attracted to the trap 12 and approach, the shape of the conical frames 3 makes it easier for them to enter and difficult for them to find an escape route, thus initially restricting the direction of their movement. Multiple conical frames 3 are each fixedly connected to multiple arc-shaped plates 4. Each arc-shaped plate 4 has a movably connected triangular plate 5 on its side near the central axis of the conical frame 3. The shape of the arc-shaped plate 4 can cooperate with the triangular plate 5 to form an openable and closable channel structure. Its smooth surface reduces obstruction to pest movement and provides a movable connection point for the triangular plate 5, allowing it to rotate flexibly around its connection with the arc-shaped plate 4. Each arc-shaped plate 4 has a fixedly connected fixing block 6 on its side near the central axis of the outer shell 1, and a semi-circular wheel 7 is fixedly connected to the side of each arc-shaped plate 4 near the central axis of the outer shell 1. The semi-circular wheel 7 has a protruding design that cooperates with the elasticity of the connecting elastic rope 8.

[0035] Reference Figures 2 to 4When pests enter, the triangular plate 5 is pushed open, and the connecting elastic rope 8 is stretched. When pests attempt to escape, the protrusion of the semi-circular wheel 7 will lock the connecting elastic rope 8, preventing the triangular plate 5 from rotating in the opposite direction and thus preventing the pests from escaping. Multiple semi-circular wheels 7 are fitted with connecting elastic ropes 8 on their exteriors. When pests are attracted to enter, their force can push open the triangular plate 5, causing it to rotate around its connection with the arc-shaped plate 4 towards the interior of the outer shell 1, allowing the pests to enter smoothly. When pests attempt to escape, the triangular plate 5, under the combined action of the semi-circular wheels 7 and the connecting elastic ropes 8, cannot rotate towards the conical frame 3, effectively preventing the pests from escaping. One end of the connecting elastic rope 8 is fixedly connected to the exterior of the fixing block 6, and the other end is fixedly connected to the exterior of the triangular plate 5. A collection frame 10 is fixedly connected to the top of the base plate 9, and the exterior of the collection frame 10 is slidably connected to the interior of the outer shell 1. The function of the collection frame 10 is to collect pests electrocuted by the electric grid frame 13. A support rod 11 is fixedly connected to the top of the collection frame 10. The support rod 11 supports the trapping tray 12, ensuring that the trapping tray 12 is at a suitable height to effectively attract pests. The trapping tray 12 is fixedly connected to the top of the support rod 11. The trapping tray 12 contains bait that attracts pests, such as food scraps or chemicals with special odors. An electric grid frame 13 is fixedly connected to the outside of the support rod 11. A power supply 14 is installed inside the collection frame 10. When the power supply 14 is energized, it generates current. Its surface is covered with a fine electric grid. When pests come into contact with the electric grid frame 13, they are electrocuted and killed. The output of the power supply 14 is electrically connected to the bottom of the electric grid frame 13 via wires, providing power to the electric grid frame 13 so that it can function properly. The top of the base plate 9 is equipped with splicing components for assembly.

[0036] Reference Figure 2 , Figure 5 and Figure 6The splicing assembly includes multiple locking blocks 15, the bottoms of which are fixedly connected to the top of the base plate 9. During splicing, the inclined surfaces of the tops of the locking blocks 15 are aligned with the bottom of the mating frames 17 and pushed upwards. The inclined surface design allows the locking blocks 15 to move upwards and insert into the mating frames 17, thus displacing the locking posts 21 under force. Each locking block 15 has a slot 16 inside. When the locking posts 21 rebound under the action of the spring 22, they can be inserted into the slot 16, thereby fixing the locking blocks 15 within the mating frames 17, completing the splicing of the base plate 9 and the outer shell 1. Multiple mating frames 17 are fixedly connected to the outside of the outer shell 1, providing space for the locking blocks 15 to insert and slide. The external sliding connection of the locking block 15 is to the inside of the mating frame 17. Multiple mating frames 17 are each slidably connected to a sliding ring 18, the external sliding connection of which is to the inside of the mating frame 17. During the assembly process, when the locking block 15 is inserted into the mating frame 17, the inclined surface of the locking block 15 pushes the locking post 21, causing the sliding ring 18 to shift within the mating frame 17, while simultaneously compressing the spring 22. When the locking post 21 aligns with the locking groove 16, the spring 22 rebounds, the sliding ring 18 returns to its original position, and the locking post 21 inserts into the locking groove 16. Each of the multiple sliding rings 18 is fixedly connected to a limiting rod 19, and each of the multiple mating frames 17 has a limiting groove 20 inside.

[0037] The function of the limiting rod 19 is to restrict the movement direction of the sliding ring 18, allowing it to slide only in the direction of the limiting groove 20, ensuring that the locking post 21 can accurately align with the locking groove 16. The limiting rod 19 is externally slidably connected to the inside of the limiting groove 20. The locking posts 21 are fixedly connected to the inside of each of the multiple sliding rings 18. Both the locking block 15 and one end of the locking post 21 are designed with an inclined surface. The external surface of the locking post 21 is externally slidably connected to the inside of the locking groove 16. During assembly, the inclined surface of the locking block 15 pushes the locking post 21, causing it to be displaced by force and compressing the spring 22. When the locking post 21 aligns with the locking groove 16, the spring 22 rebounds, and the locking post 21 inserts into the locking groove 16, thus fixing the locking block 15. Multiple locking posts 21 are fitted with springs 22 on their exteriors. One end of the spring 22 is fixedly connected to the exterior of the sliding ring 18, and the other end of the spring 22 is fixedly connected to the exterior of the pull plate 23. Pull plates 23 are fixedly connected to the opposite sides of the multiple locking posts 21. When disassembly is required, the pull plate 23 is pulled to overcome the elastic force of the spring 22, so that the locking posts 21 are disengaged from the locking slots 16, thereby realizing the separation of the base plate 9 from the outer shell 1.

[0038] Working Principle: When using this insect-trapping structure, first align the locking block 15 on the top of the base plate 9 with the bottom of the docking frame 17, then align it upwards. The inclined surface design of the locking block 15 and the locking post 21 causes the locking block 15 to move upwards and insert into the docking frame 17, resulting in displacement of the locking post 21. This displacement causes the sliding ring 18 to move, compressing the spring 22. When the locking post 21 aligns with the inside of the slot 16, the spring 22 rebounds, resetting the sliding ring 18. This allows the locking post 21 to insert into the slot 16, thus fixing the locking block 15. This completes the connection between the base plate 9 and the outer shell 1. The operation is simple and easy to assemble. Then, the trapping disc 12 can be used to attract insects. Attracting pests, the pests will crawl through the cone-shaped frame 3 into the interior of the outer shell 1. The pests will push open the triangular plate 5, causing it to rotate around the connection between the triangular plate 5 and the arc-shaped plate 4 towards the interior of the outer shell 1, allowing the pests to enter. When the pests attempt to escape, the semi-circular wheel 7 and the connecting elastic rope 8 work together. The protruding design of the semi-circular wheel 7 and the elasticity of the connecting elastic rope 8 prevent the triangular plate 5 from rotating around the connection between the triangular plate 5 and the arc-shaped plate 4 towards the interior of the cone-shaped frame 3, thus effectively preventing the pests from escaping. At the same time, with the electric grid frame 13 powered by the power source 14, the pests will be killed, and the cone-shaped design of the electric grid frame 13 will cause the pests to fall into the collection frame 10 for collection.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
