Description

Technical Field

[0001] This utility model belongs to the field of fishing hook technology, specifically a knotless, easy-to-hang connector for fishing lines. Background Technology

[0002] In fishing, the connection between the leader and the main line is crucial for ensuring the rig's stability and flexibility. Traditional leader connection methods typically involve knotting or using swivels, but these methods have significant drawbacks. For example, knotting can easily lead to the leader coming off due to loose knots or uneven stress, especially when facing large fish or complex water conditions, making it unreliable. While traditional swivels simplify the connection process, their design often fails to effectively prevent the leader from rotating or slipping under stress, resulting in an unstable connection and affecting fishing performance.

[0003] Furthermore, existing connectors often detach from the swivel due to poor design, especially underwater when subjected to fish pulling or water currents, causing the rig to fail. This not only increases the angler's workload but may also result in missed fishing opportunities. Therefore, there is an urgent need for a simple, stable, and easy-to-use knotless leader connector to solve the aforementioned problems in existing technologies.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a jointless sub-wire easy-hanging connector. Summary of the Invention

[0005] The purpose of this invention is to provide a knotless, easy-to-hang connector. Through its unique arc design and anti-detachment barb structure, it significantly improves the reliability of the connection and the ease of operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a knotless sub-wire easy-hang connector, including a hook and a rod; the hook adopts an arc design and has an anti-detachment barb structure at the end for locking after hanging; one end of the rod is connected to the hook, and the surface of the hook is provided with a spiral texture to enhance friction, and a strap can be attached to the spiral texture to connect the main wire.

[0007] Preferably, the arc-shaped design of the hook meets the shape requirements of the figure-eight ring, and the anti-detachment barb structure can effectively prevent the connector from falling off the figure-eight ring after it is attached.

[0008] Preferably, the texture of the hook surface is evenly distributed.

[0009] Preferably, the anti-detachment barb structure includes at least two serrated protrusions arranged in opposite directions; the maximum outer diameter of the barb structure is greater than the minimum inner diameter of the arc-shaped segment of the hook.

[0010] Preferably, the pitch of the hook is 0.2-0.5 mm and the texture depth is 0.1-0.3 mm; the hook covers at least 50% of the length of the rod.

[0011] Preferably, the arc-shaped opening of the hook forms an angle of 30-60 degrees with the axial direction of the rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model achieves a self-locking function for the connector through the combination of the arc-shaped design of the hook and the anti-detachment barb structure at the end. When the figure-eight ring is attached, the reverse serrated protrusions of the barb structure can automatically lock into the ring. The design that its maximum outer diameter is greater than the minimum inner diameter of the arc-shaped section of the hook ensures mechanical self-locking, effectively solving the problem of easy detachment of traditional connectors. It has been tested and can withstand a tensile force of more than 15kg without loosening.

[0014] 2. This invention significantly improves connection stability through an optimized spiral texture design. The texture uses a combination of parameters: 0.2-0.5mm pitch and 0.1-0.3mm depth, ensuring sufficient friction while preventing damage to the fishing line. Experiments show that this design increases the bonding strength between the connector and the main line by more than 40% and effectively prevents rotational slippage at the connection point.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] Example 1: This utility model provides a knotless sub-wire easy-hang connector, including a hook part 3 and a rod part 1; the hook part 3 adopts an arc design and has an anti-detachment barb structure at the end for locking after hanging; one end of the rod part 1 is connected to the hook part 3, and the surface of the hook part 3 is provided with a spiral texture 2 to enhance friction. The spiral texture 2 can be combined with a strap to connect the main wire.

[0025] During the process, the worker first wraps the main line around the spiral texture 2 of the hook 3 3-4 times, ensuring that each turn fits tightly; then, a special strap is used to fix the main line in the spiral texture 2 area; finally, the hook 3 is pushed into the figure-eight ring at a specific angle, and the barb structure automatically locks in place.

[0026] The above steps ensure a secure connection between the main line and the connector, enabling quick and easy connection and preventing the connector from accidentally falling off during use.

[0027] 1. In one embodiment of the present invention, the arc-shaped design of the hook 3 conforms to the shape requirements of hanging the figure-eight ring, and the anti-detachment barb structure can effectively prevent the connector from falling off the figure-eight ring after hanging.

[0028] During operation, the worker aligns the curved part of hook 3 with the opening of the figure-eight ring; applies slight pressure to make hook 3 slide into the figure-eight ring; the barb structure automatically pops open and locks into the inner wall of the figure-eight ring.

[0029] The above method enables one-click quick connection, ensuring the connector remains stable under various external forces and preventing it from falling off due to the fish struggling during fishing.

[0030] 2. In one embodiment of the present invention, the texture on the surface of the hook 3 is evenly distributed.

[0031] During operation, the worker smoothly attaches the main line to the surface of the hook 3; evenly winds the main line along the spiral texture 2; ensuring that each turn of the main line is embedded in the texture groove.

[0032] The structure described above provides a uniform distribution of friction, preventing the main line from sliding or shifting under stress and ensuring consistent connection strength.

[0033] 3. In one embodiment of the present invention, the anti-detachment barb structure includes at least two serrated protrusions arranged in opposite directions; the maximum outer diameter of the barb structure is greater than the minimum inner diameter of the arc-shaped segment of the hook.

[0034] When the worker pushes the hook 3 into the figure-eight ring, the serrated protrusion of the barb is squeezed and temporarily deformed; after it is fully inserted, the barb returns to its original shape, and the protrusion gets stuck in the inner wall of the figure-eight ring.

[0035] The above-mentioned bidirectional locking prevents forward and backward movement, ensures that the connector can only be disassembled in a specific way, and provides reliable tensile strength.

[0036] 4. In one embodiment of the present invention, the pitch of the hook portion 3 is 0.2-0.5mm and the texture depth is 0.1-0.3mm; the hook portion 3 covers at least 50% of the length of the rod portion.

[0037] During operation, workers select the appropriate number of wraps based on the diameter of the main line; utilize the pitch and depth of the texture to ensure the main line is firmly fixed; and distribute the force through sufficient coverage length.

[0038] The above structure allows the device to adapt to main lines of different diameters, optimizes the balance between friction and line protection, and improves the durability of the connection parts.

[0039] 5. In one embodiment of the present invention, the arc-shaped opening direction of the hook 3 forms an angle of 30-60 degrees with the axial direction of the rod 1.

[0040] During operation, the staff holds the rod 1 at a natural grip angle; the opening angle of the hook 3 automatically aligns with the figure-eight ring; the hook can be attached without special adjustment.

[0041] Rod 1: Made of 304 stainless steel (GB / T 3280-2015 standard), with a diameter of 1.2mm ± 0.05mm, a length of 15mm, and a surface roughness Ra≤0.8μm;

[0042] Hook 3: Made of TC4 titanium alloy (GB / T 3620.1-2016 standard), with an arc radius of 3.5mm, and connected to the rod at an angle of 45°±2°;

[0043] Anti-detachment barb structure: It includes two sets of symmetrically distributed serrated protrusions, with 3 protrusions in each set. The height of each protrusion is 0.4mm and the spacing is 0.3mm.

[0044] Spiral Texture 2: Left-handed design, pitch 0.35mm±0.02mm, depth 0.2mm±0.02mm, coverage area 60%.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
