Description

Technical Field

[0001] The present invention relates to the technical field of insect catching, and particularly relates to a portable insect-catching device with a cavity structure. Background Art

[0002] Currently, in the fields of insect research, specimen making, etc., it is often necessary to catch insects. Traditional insect-catching nets usually require users to wave them manually to catch insects. For insects such as butterflies with fast flight speeds and flexible flight trajectories, the catching difficulty is relatively large and the success rate is relatively low. Existing insect-catching tools are difficult to meet the need for efficiently catching such insects. Therefore, we propose a portable insect-catching device with a cavity structure to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a portable insect-catching device with a cavity structure.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A portable insect-catching device with a cavity structure, including a protective housing. In the middle of the protective housing, there is a spraying pipeline. A pull rod penetrates through the spraying pipeline. One end of the pull rod is connected with an elastic mechanism. The middle of the pull rod is clamped with a limiting mechanism. At the bottom of the protective housing, there is a rotating structure, and the rotating structure corresponds to the limiting mechanism. On one side of the bottom of the protective housing, there is a clamping mechanism, and the clamping mechanism corresponds to the rotating structure. One end of the spraying pipeline is screwed with a spray pipe, and a net-throwing structure is arranged in the spray pipe.

[0006] Preferably, the spraying pipeline includes a conveying pipe fixed in the middle of the protective housing. One end of the conveying pipe is connected with a connecting pipe. One end of the connecting pipe is connected with a threaded joint. The pull rod penetrates through the conveying pipe. One end of the pull rod is fixed with a push rod, and one end of the push rod penetrates through the connecting pipe.

[0007] Preferably, the elastic mechanism includes a fixing plate fixed at the upper end of the pull rod. One end of the fixing plate is equally spaced and connected with five second springs. One side of the protective housing is fixed with a backing plate. One end of the spring abuts against one side of the backing plate. The pull rod penetrates through one of the springs. One end of the pull rod is connected with a pull handle.

[0008] Preferably, the limiting mechanism includes a cushion block fixed on one side of the top of the protective housing. The lower end of the cushion block is connected with a first spring. The lower end of the first spring is connected with a clamping frame. There is a clamping groove corresponding to the clamping frame on one side of the upper end of the pull rod, and the clamping frame is clamped in the clamping groove.

[0009] Preferably, the rotating mechanism includes a movable block rotatably connected to one side of the inner bottom of the protective housing through a rotating shaft. One side of the upper end of the movable block abuts against one side of the upper end of the clamping frame. One end of the movable block is connected to a trigger. One side of the inner bottom of the protective housing is provided with a support shaft, and one end of the trigger abuts against the support shaft. One end of the trigger penetrates through the side wall of the protective housing and extends to the lower end of the protective housing.

[0010] Preferably, the clamping mechanism includes a servo motor fixed to one side of the inner bottom of the protective housing. The end of the output shaft of the servo motor is connected to a gear set. One end of the gear set is connected to a turntable. One end of the turntable is fixed with a limiting rod. One side of the upper end of the trigger is provided with a limiting groove. One end of the limiting rod abuts against one side of the limiting groove.

[0011] Preferably, one end of the spray pipe is connected with a threaded sleeve. The inner side wall of the threaded sleeve is provided with internal threads, and the threaded joint is screwed onto the internal threads.

[0012] Preferably, the net-throwing structure includes a rubber pad penetrating through the spray pipe. One end of the rubber pad is connected with a catching net.

[0013] Preferably, one side of the lower end of the protective housing is fixed with a handle, and the other side of the lower end of the protective housing is fixed with a protective sleeve.

[0014] Preferably, a switch is installed on one side of the protective housing, and the switch is connected to the servo motor.

[0015] In the present invention, the spray pipe is a hollow structure with a length of half a meter. Its function is to accommodate the catching net and serve as a carrier for ejection. The cavity is made of a lightweight and high-strength material, which not only ensures sufficient strength to withstand the force during the ejection process but also facilitates the user to carry and operate. When the trigger is pulled, one end of the movable block moves upward, thereby driving the clamping frame to move upward, so as to move it out of the card slot. Driven by the reset of the second spring, the rapid release of the pull rod and the push rod is realized. By the rapid impact of the push rod on the rubber pad, the catching net can be quickly ejected from the cavity in an instant. The mechanism utilizes the principle of spring energy storage to ensure that the catching net has sufficient speed and coverage.

[0016] In the present invention, the diameter of the catching net can reach 1 meter to 1.5 meters after being unfolded, which can effectively cover insects in a large range. The net body is made of a fine material, which can not only ensure that insects cannot easily escape but also has a certain flexibility and is not easily damaged during the ejection process. The trigger is arranged outside the cavity, which is convenient for the user to operate. The connection design between the trigger and the ejection mechanism ensures the sensitivity and reliability of the operation. The user only needs to gently pull the trigger to realize the ejection of the catching net. Through the setting of the clamping mechanism.

[0017] In the present invention, when in use, one hand holds the handle and holds the trigger with a finger to lift the clamping frame, and then the other hand pulls the pull rod backward through the pull handle to squeeze the second spring. After reaching the predetermined position, the trigger is released, and the clamping frame is lowered under the reset drive of the first spring, and the pull rod is firmly clamped. At the same time, the clamping mechanism drives the gear set to rotate through the rotation of the servo motor, thereby driving the turntable to rotate, so that the limit rod is abutted in the limit groove to prevent accidental touching of the trigger and causing accidental firing, thereby improving the safety of use. When firing is needed, one hand holds the handle and the other hand holds up the protective cover and presses the switch at the same time to unlock the clamping mechanism, drive the limit rod to move out of the limit groove, and then pull the trigger to realize firing.

[0018] The present invention has the following advantages:

[0019] 1. By utilizing the spring energy storage principle, the insect net is ensured to have sufficient speed and coverage to improve the adequacy of capture;

[0020] 2. The insect net can quickly spray and cover the flying insects, greatly improving the success rate of catching butterflies and other insects with strong flying ability;

[0021] 3. The connection between the trigger and the rotating mechanism ensures the sensitivity and reliability of the operation. The user only needs to gently pull the trigger to eject the insect net;

[0022] 4. The setting of the card connection mechanism can prevent dangerous emission caused by accidental touch and improve the safety of use;

[0023] In summary, the present invention is different from the traditional manually-swung insect net. The insect net is quickly ejected to quickly cover the flying insects, greatly improving the success rate of catching insects with strong flying abilities such as butterflies. At the same time, after the target insect is found, the capture action can be completed by pulling the trigger. No complicated operating skills are required, which lowers the threshold for use. In addition, it can prevent dangerous launches caused by accidental touches, thereby improving the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Refer to Figures 1-9 , a portable insect-catching device with a cavity structure, including a protective housing 4. A spraying pipeline is provided in the middle of the protective housing 4. A pull rod 11 penetrates through the spraying pipeline. One end of the pull rod 11 is connected with an elastic mechanism. A limiting mechanism is clamped in the middle of the pull rod 11. A rotating structure is provided at the bottom of the protective housing 4, and the rotating structure corresponds to the limiting mechanism. A clamping mechanism is provided on one side of the bottom of the protective housing 4, and the clamping member mechanism corresponds to the rotating structure. One end of the spraying pipeline is screwed with a spray pipe 23. A throwing net structure is provided in the spray pipe 23. One end of the spray pipe 23 is connected with a threaded sleeve 24. An internal thread 31 is provided on the circumferential side wall inside the threaded sleeve 24. The threaded joint 1 is screwed onto the internal thread 31. A grip 19 is fixed on one side of the lower end of the protective housing 4, and a protective sleeve 25 is fixed on the other side of the lower end of the protective housing 4. Taking the protective housing 4 as the core load-bearing component, multiple key mechanisms are integrated inside it. Each mechanism works together to achieve an efficient, safe and convenient insect-catching function. The protective housing 4 not only provides stable support and protection for the internal mechanisms, but also designs external components convenient for users to operate, such as the grip 19 and the protective sleeve 25, fully considering the ergonomic principle and improving the comfort and convenience of use;

[0036] The injection pipeline includes a delivery pipe 3 fixed in the middle of the protective housing 4. One end of the delivery pipe 3 is connected with a connecting pipe 2, and one end of the connecting pipe 2 is connected with a threaded joint 1. A pull rod 11 passes through the delivery pipe 3. One end of the pull rod 11 is fixed with a push rod 26, and one end of the push rod 26 passes through the connecting pipe 2, ensuring that the pull rod 11 and the push rod 26 can move smoothly in the injection pipeline, providing a stable power transmission path for the subsequent injection of the throwing net;

[0037] The elastic mechanism includes a fixing plate 8 fixed at the upper end of the pull rod 11. Five second springs 9 are equidistantly connected to one end of the fixing plate 8. One side inside the protective housing 4 is fixed with a backing plate 10. One end of the spring 9 abuts against one side of the backing plate 10. The pull rod 11 passes through one of the springs 9. One end of the pull rod 11 is connected with a pull handle 12. When the user pulls the pull rod 11 backward through the pull handle 12, the second spring 9 is compressed and stores elastic potential energy. When releasing the pull rod 11 at an appropriate time, the restoring force of the second spring 9 will drive the pull rod 11 and the push rod 26 to be quickly released, providing power for the injection of the throwing net. The spring energy storage method can ensure that the throwing net has sufficient speed and strength to effectively cover a large range of insects;

[0038] The limiting mechanism includes a cushion block 7 fixed on one side of the inner top of the protective housing 4. The lower end of the cushion block 7 is connected with a first spring 6, and the lower end of the first spring 6 is connected with a clamping frame 21. One side of the upper end of the pull rod 11 is provided with a clamping groove 30 corresponding to the clamping frame 21, and the clamping frame 21 is clamped in the clamping groove 30. In the normal state, the clamping frame 21 is clamped in the clamping groove 30 to firmly fix the pull rod 11 and prevent it from moving accidentally. When it is necessary to launch the throwing net, by operating the rotating mechanism, the clamping frame 21 is driven to move upward, so that it moves out of the clamping groove 30, thereby releasing the pull rod 11. The setting of the limiting mechanism ensures the stability and reliability of the pull rod 11 during the storage and release of elastic potential energy;

[0039] The rotating mechanism includes a movable block 20 rotatably connected to one side of the inner bottom of the protective housing 4 through a rotating shaft 18. One side of the upper end of the movable block 20 abuts against one side of the upper end of the clamping frame 21. One end of the movable block 20 is connected with a trigger 16. One side of the inner bottom of the protective housing 4 is provided with a support shaft 17, and one end of the trigger 16 abuts against the support shaft 17. One end of the trigger 16 passes through the side wall of the protective housing 4 and extends to the lower end of the protective housing 4. The support shaft 17 is installed on one side of the inner bottom of the protective housing 4 to provide a support point for the trigger 16. When the user pulls the trigger 16, the trigger 16 rotates around the support shaft 17, driving one end of the movable block 20 to move upward, and then driving the clamping frame 21 to move upward, realizing the unlocking of the pull rod 11, enabling the user to conveniently and sensitively control the launch of the throwing net;

[0040] The clamping mechanism includes a servo motor 13 fixed to one side of the inner bottom of the protective housing 4. The end of the output shaft of the servo motor 13 is connected to a gear set 14. One end of the gear set 14 is connected to a turntable 15. One end of the turntable 15 is fixed with a limiting rod 5. One side of the upper end of the trigger 16 is provided with a limiting groove 29. One end of the limiting rod 5 abuts against one side of the limiting groove 29. After the pull rod 11 is fixed by the clamping frame 21, the servo motor 13 rotates to drive the gear set 14 to rotate, and then drives the turntable 15 to rotate, so that the limiting rod 5 abuts in the limiting groove 29, preventing accidental touching of the trigger 16 and causing accidental firing, greatly improving the safety of equipment use. One side of the protective housing 4 is installed with a switch 22, and the switch 22 is connected to the servo motor 13. The switch 22 and the servo motor 13 are connected by a power line and a signal line. The power line is connected to a 12V lithium battery pack through a 16AWG silver-plated wire. The signal line integrates an opto-isolation module to prevent electromagnetic interference. When the switch 22 is pressed, the following chain reaction is triggered:

[0041] 1. The servo motor 13 receives a pulse signal (duration ≥ 200 ms);

[0042] 2. The gear set 14 drives the turntable 15 to rotate at a speed of 15 rpm;

[0043] 3. The limiting rod 5 and the limiting groove 29 form a displacement difference of 3 mm;

[0044] 4. The active range of the unlocked trigger 16 is expanded from ±5° to ±25°, and the whole process takes 0.8 - 1.2 seconds to ensure the reliability and response speed of the unlocking action;

[0045] The net-throwing structure includes a rubber pad 28 penetrating through a nozzle 23. One end of the rubber pad 28 is connected to a net 27. The rubber pad 28 penetrates through the nozzle 23 and one end of it is connected to the net 27. When the push rod 26 quickly impacts the rubber pad 28, the insect-catching net 27 can be quickly ejected from the cavity instantly. After the insect-catching net 27 is unfolded, its diameter can reach 1 to 1.5 meters. Made of a fine material, it can not only ensure that insects cannot escape easily, but also has a certain flexibility and is not easily damaged during the ejection process;

[0046] In the present invention, the nozzle 23 is a hollow structure with a length of half a meter. Its function is to accommodate the insect-catching throwing net 27 and serve as a carrier for ejection. The cavity is made of a lightweight and high-strength material, which not only ensures sufficient strength to withstand the force during the ejection process but also facilitates the user to carry and operate. When the trigger 16 is pulled, one end of the movable block 20 is driven to move upward, thereby driving the clamping frame 21 to move upward, and then moving it out of the card slot 30. Driven by the reset of the second spring 9, the pull rod 11 and the push rod 26 are quickly released. By the quick impact of the push rod 26 on the rubber pad 28, the insect-catching throwing net 27 can be quickly ejected from the cavity. The mechanism utilizes the principle of spring energy storage to ensure that the insect-catching net has sufficient speed and coverage range.

[0047] In the present invention, after the insect-catching throwing net 27 is unfolded, its diameter can reach 1 meter to 1.5 meters, which can effectively cover a large range of insects. The net body is made of a fine material, which can not only ensure that insects cannot easily escape but also has a certain flexibility and is not easily damaged during the ejection process. The trigger 16 is arranged outside the cavity, which is convenient for the user to operate. The connection design between the trigger and the ejection mechanism ensures the sensitivity and reliability of the operation. The user only needs to gently pull the trigger to eject the insect-catching net. Through the setting of the clamping mechanism.

[0048] In the present invention, during use, one hand holds the grip 19 and uses a finger to hold the trigger 16, causing the clamping frame 21 to be lifted. Then, the other hand pulls the pull rod 11 backward through the pull handle 12 to compress the second spring 9. After reaching the predetermined position, the trigger 16 is released. Driven by the reset of the first spring 6, the clamping frame 21 descends to firmly clamp the pull rod 11. At the same time, the clamping mechanism drives the gear set 14 to rotate through the rotation of the servo motor 13, thereby driving the turntable 15 to rotate, so that the limit rod 5 abuts against the limit groove 29 to prevent accidental touching of the trigger 16 and causing accidental firing, improving the safety of use. When firing is required, one hand holds the grip 19, and the other hand holds up the protective cover 25 and presses the switch 22 at the same time to unlock the clamping mechanism, driving the limit rod 5 to move out of the limit groove 29, and then pulling the trigger 16 to fire.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
