Description

Technical Field

[0001] This invention relates to the field of fishing net technology, specifically to a mesh adaptive adjustment device for fishing nets. Background Technology

[0002] A fishing net's mesh refers to a perforated structure made of netting threads arranged in a designed shape; it is the basic structural unit of the net. A mesh consists of a mesh foot, a knot, or a mesh connection point. Mesh size typically refers to the size of the mesh used in fishing operations, usually expressed as the diagonal length of the mesh or the length of the mesh foot. Different fish species vary in size at different growth stages, and different fish species also have different body shapes. Through adaptive mesh adjustment, the mesh size can be precisely adjusted for different target fish species and their growth stages, effectively capturing target fish, reducing empty nets, and improving fishing efficiency.

[0003] When using fishing nets, first check that the net is intact, and select the appropriate handle and mesh size according to the scenario. Observe the target while operating, approach slowly from the side and below, tilt the net frame at a 30-45 degree angle, quickly scoop up the prey, and lift the net out of the water, taking care to avoid injury when retrieving it. Clean thoroughly after use and store properly. Be mindful of protecting aquatic resources, operate safely, and minimize environmental disturbance.

[0004] In existing technologies, some fishing nets are used to scoop up fish during use. Since there are fish of different sizes in the same water, if the mesh is too large, small fish will easily escape, while if the mesh is too small, it will increase water resistance, reduce the scooping speed, and even cause large fish to break out of the net while struggling due to the weight of the net, thus reducing the flexibility of fishing. Therefore, in order to address the above shortcomings, a mesh adaptive adjustment device for fishing nets is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adaptive mesh adjustment device for fishing nets, which solves the problem that some fishing nets cannot adjust the mesh size according to the size of the fish being caught, resulting in reduced flexibility.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mesh adaptive adjustment device for a fishing net, comprising a handle, a support mechanism slidably connected inside the handle, an adjustment mechanism fixedly connected to the left side of the support mechanism, a sliding mechanism fixedly connected to the right end of the handle, and a reinforcing mechanism fixedly connected to the right side of the handle. The adjustment mechanism includes an outer ring, the right side of which is fixedly connected to the left side of the support mechanism, an outer net fixedly connected to the bottom side of the outer ring, a base fixedly connected to the bottom side of the outer net, two connecting blocks slidably connected inside the outer ring, an inner ring fixedly connected to the adjacent side of the two connecting blocks, an inner net fixedly connected to the bottom side of the inner ring, a sliding plate slidably connected inside the connecting blocks, and a reset component fixedly connected to the bottom side of the sliding plate.

[0007] Preferably, the support mechanism includes an adjusting rod, the adjusting rod being slidably connected to the outside of the handle, a positioning rod being fixedly connected to the inside of the adjusting rod, a rotating plate being rotatably connected to the outside of the positioning rod, an open plate being fixedly connected to the left side of the rotating plate, elastic elements being fixedly connected to both the front and rear sides of the rotating plate, a rotating plate being rotatably connected to the right end of the rotating plate, a limiting disc being fixedly connected to the right side of the rotating plate, and a support cone being fixedly connected to the right side of the limiting disc.

[0008] Preferably, the left side of the adjusting rod is fixedly connected to the right side of the outer ring, and the bottom side of the adjusting rod has multiple limiting openings.

[0009] Preferably, the sliding mechanism includes an anti-slip sleeve, the inside of which is fixedly connected to the right end of the handle, a sliding ring is slidably connected inside the anti-slip sleeve, a fixing plate is fixedly connected to the top side of the sliding ring, a connecting block is fixedly connected to the bottom side of the inner wall of the sliding ring, and a spring is fixedly connected to the bottom side of the sliding ring.

[0010] Preferably, the reinforcement mechanism includes a concave plate, the left side of which is fixedly connected to the right side of the handle, a rotating block is rotatably connected inside the concave plate, a connecting plate is fixedly connected to the right side of the rotating block, and a reinforcement cone is fixedly connected to the right side of the connecting plate.

[0011] Preferably, both of the reset components include a limiting plate, the outside of which is slidably connected to the inside of the connecting block, and a spring is fixedly connected to the far end of each of the two limiting plates.

[0012] Preferably, the two springs are respectively fixedly connected to the opposite sides of the inner walls of the two connecting blocks, and the outer ring has multiple square openings inside.

[0013] Preferably, the outer side of the limiting plate is slidably connected to the inside of the square opening, and the bottom side of the inner mesh is fixedly connected to the top side of the chassis.

[0014] Preferably, the outer side of the fixing plate is slidably connected to the inside of the anti-slip sleeve, and the outer side of the connecting block is slidably connected to the inside of the plurality of limiting openings.

[0015] Preferably, the bottom end of the second spring is fixedly connected to the bottom side of the inner wall of the handle, and the outside of the fixing plate is slidably connected to the inside of the right end of the handle.

[0016] This invention provides a mesh adaptive adjustment device for fishing nets. It has the following beneficial effects: 1. This invention drives the inner net to rotate, causing the inner net's mesh to interlock with the outer net's mesh. After rotating to the appropriate position, the pushing force on the sliding plate is released, and the spring's return force is transmitted to the limiting plate, which engages with the inside of the square opening for fixation. This achieves the function of adjusting the net and thus improves its fishing flexibility.

[0017] 2. This invention uses the rotation of the rotating plate to drive the opening plate to rotate upward, providing support for the fishing rod. Then, rotating the rotating plate drives the limiting plate to rotate, and finally drives the support cone to rotate vertically downward and penetrate into the soil. The connecting plate also drives the reinforcing cone to rotate vertically downward and penetrate into the soil for reinforcement, thus achieving the function of simulating auxiliary fishing tackle and having a multi-functional effect.

[0018] 3. The distance can be adjusted by sliding the handle and the adjusting rod. After sliding to the corresponding position, the pushing force on the fixed plate is released, and the sliding ring is pushed to slide by the force of the spring two returning to its original position. Then, the connecting block is slid and locked into the inside of the limiting opening for fixation, thus completing the adjustment. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 Appendix Figure 7 and attached Figure 8 This invention provides a mesh adaptive adjustment device for fishing nets, including a handle 1. The handle 1, used as a handheld component by the operator, is made of non-slip, durable rubber material, facilitating stable grip and providing a convenient point of leverage throughout the operation. A support mechanism 2 is slidably connected inside the handle 1, allowing the support mechanism 2 to slide within the handle 1 and adjust its extension or retraction length to adapt to different fishing scenarios and operational needs. The support mechanism 2 includes an adjusting rod 21, which serves as both support and connection. The adjusting rod 21 is slidably connected to the inside of the handle 1, allowing it to move flexibly relative to the handle 1, enabling the operator to adjust the position of the support mechanism 2 according to actual conditions. A positioning rod 22 is fixedly connected inside the adjusting rod 21 by welding, providing support for the positioning rod 22. A rotating plate 23 is rotatably connected to the outside of the positioning rod 22, allowing the rotating plate 23 to rotate around the positioning rod 22. An open plate 24 is fixedly connected to the left side of the rotating plate 23. The rotating plate 23 rotates around the positioning rod 22. After the rotating plate 23 rotates the open plate 24 to a vertical position, the open plate 24 supports the fishing tackle, thus improving its flexibility. Elastic elements 25, made of rubber, are fixedly connected to both the front and rear sides of the rotating plate 23. When the rotating plate 23 rotates, the elastic elements 25 deform, and after the external force disappears, they can drive the rotating plate 23 back to its initial position. A rotating plate 26 is rotatably connected to the right end of the rotating plate 23, providing support for the rotating plate 26 via an shaft, allowing it to rotate. A limiting disc 27 is fixedly connected to the right side of the rotating plate 26 by welding, providing support for the limiting disc 27. A support cone 28 is fixedly connected to the right side of the limiting disc 27. The support cone 28 has a sharp end, making it easy to insert into the ground for support, thus functioning as an auxiliary lifting device and providing different functions. Multiple limiting openings 29 are provided on the bottom side of the adjusting rod 21. These limiting openings 29 are evenly distributed on the bottom side of the adjusting rod 21 and are square. Please see the appendix Figure 2 - Appendix Figure 4 An adjustment mechanism 3 is fixedly connected to the left side of the support mechanism 2. The adjustment mechanism 3 is used to achieve adaptive adjustment of the mesh size. The adjustment mechanism 3 includes an outer ring 34. The left side of the adjustment rod 21 is fixedly connected to the right side of the outer ring 34 by welding, so that the movement of the support mechanism 2 can be transmitted to the adjustment mechanism 3. The right side of the outer ring 34 is fixedly connected to the left side of the support mechanism 2, which further enhances the connection stability between the outer ring 34 and the support mechanism 2, ensuring that there is no relative displacement between the two during operation. An outer net 35 with a relatively large mesh size is fixedly connected to the bottom side of the outer ring 34. A base 36 is fixedly connected to the bottom side of the outer net 35, which forms a relatively closed fishing space to prevent the catch from escaping from the bottom. The bottom side of the inner net 32 ​​is fixedly connected to the top side of the base 36. The inner net 32 ​​with a relatively small mesh size is adjusted by interleaving the inner net 32 ​​with the outer net 35. Two connecting blocks 33 are symmetrically distributed inside the outer ring 34 and slide along the inner wall of the outer ring 34, providing support and guidance for the movement of the inner ring 31. The inner ring 31 is fixedly connected to the adjacent side of the two connecting blocks 33. The sliding of the connecting blocks 33 can drive the inner ring 31 to move synchronously, thereby adjusting the shape of the inner net 32. The inner net 32 ​​is fixedly connected to the bottom side of the inner ring 31. By rotating the inner ring 31, the mesh size of the inner net 32 ​​can be changed, achieving adaptive adjustment of the mesh size.

[0023] Please see the appendix Figure 4 - Appendix Figure 6A sliding plate 37 is slidably connected inside the connecting block 33. The connecting block 33 restricts the sliding plate 37, allowing it to slide stably. Multiple square openings 38 are provided inside the outer ring 34. These square openings 38 are adapted to the sliding plate 37. When the sliding plate 37 engages with different square openings 38, the positions of the connecting block 33 and the inner ring 31 are fixed, thus determining the mesh size of the inner mesh 32. A reset assembly 39 is fixedly connected to the bottom side of the sliding plate 37, providing a reset effect. Both reset assemblies 39 include a limiting plate 391, which is rectangular. The limiting plate 391 is slidably connected to the inside of the square opening 38, allowing it to slide within the square opening 38 and engage or disengage. The limiting plate 391 is also slidably connected to the inside of the connecting block 33, ensuring stable sliding within the connecting block 33 and providing guidance for its engagement with the square opening 38. Spring 392 is fixedly connected to the distal ends of both limiting plates 391. Spring 392 provides elastic restoring force to the limiting plates 391. When the limiting plates 391 are compressed by external force, they can disengage from the square opening 38. After the external force disappears, spring 392 restores its deformation, causing the limiting plates 391 to engage with the square opening 38. The distal ends of the two springs 392 are respectively fixedly connected to the distal sides of the inner walls of the two connecting blocks 33, fixing the springs 392 to the inner walls of the connecting blocks 33 and providing stable support for the springs 392, ensuring that their elastic force can effectively act on the limiting plates 391.

[0024] Please see the appendix Figure 7 -Appendix Figure 8 A sliding mechanism 4 is fixedly connected to the right end of the grip 1. The sliding mechanism 4 includes an anti-slip sleeve 41. The surface of the anti-slip sleeve 41 is usually provided with anti-slip texture to increase the friction between the operator's hand and the grip 1, preventing slippage during operation. The anti-slip sleeve 41 is internally fixedly connected to the right end of the grip 1, ensuring that the anti-slip sleeve 41 and the grip 1 are integrated and will not slide relative to each other during operation. A sliding ring 42 is slidably connected inside the anti-slip sleeve 41, and the sliding ring 42 can slide up and down inside the anti-slip sleeve 41 to prevent the sliding ring 42 from shifting. A fixing plate 43 is fixedly connected to the top side of the sliding ring 42, which serves to connect and fix, ensuring the stability of the sliding ring 42 when sliding. The fixing plate 43 is externally slidably connected to the inside of the right end of the grip 1, allowing the fixing plate 43 to slide together with the sliding ring 42 inside the grip 1, while also guiding the sliding direction of the sliding ring 42. The fixed plate 43 is externally slidably connected to the inside of the anti-slip sleeve 41. The anti-slip sleeve 41 restricts the stability of the fixed plate 43 when it slides, ensuring its accurate movement trajectory. A connecting block 44 is fixedly connected to the bottom inner wall of the sliding ring 42. The shape of the connecting block 44 is adapted to the limiting opening 29. The external part of the connecting block 44 is slidably connected to the inside of multiple limiting openings 29. When the connecting block 44 is engaged in different limiting openings 29, the adjusting rod 21 can be fixed in the corresponding position, thereby determining the extension length of the support mechanism 2. A second spring 45 is fixedly connected to the bottom side of the sliding ring 42. The second spring 45 provides an upward elastic force to the sliding ring 42. When the operator releases the sliding ring 42, the second spring 45 can drive the sliding ring 42 to return to its original position, causing the connecting block 44 to engage in the limiting opening 29. The bottom end of the second spring 45 is fixedly connected to the bottom inner wall of the handle 1, fixing the second spring 45 to the bottom inner wall of the handle 1 and providing stable support for the second spring 45 to ensure that it can perform its elastic return function normally.

[0025] Please see the appendix Figure 1 and attached Figure 8 A reinforcing mechanism 5 is fixedly connected to the right side of the handle 1. The reinforcing mechanism 5 prevents the net from tipping over or shifting due to external forces when used for lifting and supporting the fishing tackle. The reinforcing mechanism 5 includes a concave plate 51, the left side of which is fixedly connected to the right side of the handle 1 by welding, thus providing support for the concave plate 51. A rotating block 52 is rotatably connected inside the concave plate 51, allowing the rotating block 52 to rotate within the concave plate 51 to adjust its angle to adapt to different support environments. A connecting plate 53 is fixedly connected to the right side of the rotating block 52 by welding, thus providing support for the connecting plate 53. A reinforcing cone 54 is fixedly connected to the right side of the connecting plate 53. The reinforcing cone 54 cooperates with the supporting cone 28 and can be inserted into the soil to reinforce the net from different angles, improving the stability of the net when used as auxiliary fishing tackle.

[0026] Working principle: Based on the size of the fish school and the required catch size, the sliding plate 37 is pushed to slide, which in turn drives the limiting plate 391 to slide. During the sliding process of the limiting plate 391, the spring 392 is compressed, allowing the spring 392 to store elastic potential energy. This then applies a force in the opposite direction to the limiting plate 391 to reset it. When the limiting plate 391 slides out of the inside of the square opening 38, the inner ring 31 can rotate, which in turn drives the two connecting blocks 33 to rotate. At the same time, the inner net 32 ​​will also rotate, causing the mesh of the inner net 32 ​​to interweave with the mesh of the outer net 35. After the rotation reaches the appropriate position, the pushing force on the sliding plate 37 is released. The reset force of the spring 392 is transmitted to the limiting plate 391, which then engages with the inside of the square opening 38 for fixation. This achieves the function of net adjustment, thereby improving the flexibility of the catch. When fishing without using the handle 1, by pushing the rotating plate 23 to continue rotating around the adjusting rod 21, the elastic element 25 will be squeezed and deformed, allowing the rotating plate 23 to rotate. Conversely, the elastic element 25 can be locked inside the adjusting rod 21. As the rotating plate 23 rotates, it will drive the opening plate 24 to rotate upward, so that it can provide support for the fishing rod. Then, the rotating plate 26 is rotated, which in turn drives the limiting plate 27 to rotate. Finally, the support cone 28 is rotated vertically downward and penetrates into the soil, so that the handle 1 and the adjusting rod 21 are tilted. Then, the rotating block 52 is pushed to rotate. Finally, the connecting plate 53 drives the reinforcing cone 54 to rotate vertically downward and penetrate into the soil for reinforcement, so that it can achieve the function of simulating auxiliary fishing gear, thereby improving its flexibility. Simultaneously, by gripping the anti-slip sleeve 41 and applying a pushing force to the fixing plate 43, the sliding ring 42 is driven to slide, followed by the sliding of the connecting block 44, which slides away from the inside of the limiting opening 29. At the same time, the sliding ring 42 will also compress the second spring 45, allowing the second spring 45 to store elastic potential energy. At this time, the handle 1 and the adjusting rod 21 can slide to adjust the distance. After sliding to the corresponding position, the pushing force on the fixing plate 43 is released, and the force of the second spring 45 returning to its original position is used to push the sliding ring 42 to slide, which then drives the connecting block 44 to slide and lock into the inside of the limiting opening 29 for fixation, thus completing the adjustment.
