Description

Technical Field

[0001] This utility model relates to fish hooks, and more particularly to a fish hook that prevents it from slipping off. Background Technology

[0002] The single hook is the most basic and widely used hook type in fishing. Its core advantages are simple structure, good bite resistance, and convenient operation. Currently, traditional single hooks on the market usually have a single barb on one side below the hook point of the main hook. The hook is fixed to the fish's mouth only by the barb on one side of the hook point of the main hook. When the fish struggles violently, the force is concentrated, making it easy for the fish to slip off from one side. Especially for large fish with large mouths and strong struggles, since the hook point of the main hook and the barb are distributed on the same longitudinal line, it is very easy for the force to shift and the fish to get off the hook. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an anti-detachment fishhook.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: an anti-detachment fishhook, including a main hook body, a sharp main hook tip formed at the front end of the main hook body, a winding line segment provided at the hook shank of the main hook body, and a threading ring integrally connected to the main hook body through the winding line segment.

[0005] The main hook tip is curved inward, and auxiliary barbs are symmetrically distributed on both sides of the main hook tip;

[0006] A main barb is provided at the junction of the main hook tip and the main hook body;

[0007] A limiting groove is provided at the winding section of the hook shank.

[0008] Preferably, the two sides of the main hook tip are formed with cut surfaces, and auxiliary barbs are provided at the cut surfaces.

[0009] Preferably, the angle between the auxiliary barb and the cut surface, and the angle between the main barb and the main hook body are both between 30° and 45°.

[0010] Preferably, the length of the main hook tip is L_main hook tip, and the gate width of the anti-loosening hook is W_hook gate; the gate width W 钩门 ≥ Main hook tip length L 主钩钩尖 1.5 times.

[0011] Preferably, the groove surface of the limiting groove is set as a rough surface.

[0012] Preferably, the thread loop is in the shape of a rounded ring.

[0013] Preferably, a sub-hook is integrally connected at the bottom of the hook bend of the main hook body, and the sub-hook is bent toward the hook shank.

[0014] Preferably, the sub-hook has a sharp sub-hook tip, and a sub-hook barb is integrally connected to the sub-hook tip.

[0015] Preferably, the surfaces of the main hook body 1 and the sub-hook 8 are both coated with a colored paint layer.

[0016] This utility model discloses an anti-get-out fishhook. The main hook tip is sharp and inwardly curved. After a fish bites the hook, the sharp hook tip can quickly penetrate the fish's mouth. The inward curvature allows the hook tip to better lock into the fish's mouth, thereby reducing the probability of the fish getting off the hook. Furthermore, auxiliary barbs are added to the left and right sides of the main hook tip, which can avoid the barbs' action point being limited to only one place. When dealing with fish with large mouths and strong struggles, even if the fishhook shifts due to force, the structure of the multi-barb layout can hook the fish with a higher probability, thus effectively reducing the probability of the fish getting off the hook.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] This embodiment discloses an anti-detachment fishhook, with a three-dimensional structure as follows: Figure 1 As shown, it includes a curved main hook body 1, with a sharp main hook tip 5 formed at the front end of the main hook body 1, such as... Figure 3As shown, the main hook tip is sharp and can quickly pierce the fish's mouth tissue when it bites. At the same time, the main hook tip 5 has an inward bending structure with a bending angle of 15-30° relative to the longitudinal plane. Through the inward bending design of the main hook tip 5, the hook tip that pierces the fish's mouth tissue can be better locked inside the fish's mouth, thereby improving the hook's anti-loosening performance.

[0027] Furthermore, the main function of the barb structure on the fishhook is to form an irreversible mechanical constraint after the hook tip penetrates. For traditional single-hook fishhooks, there is usually a set of barbs, namely the main barb 2 corresponding to the anti-loosening fishhook in this embodiment. The main barb 2 is located at the connection position between the main hook tip 5 and the main hook body 1, and is located below the main hook tip 5. When the fish bites the hook, the main barb 2 acts as a reverse contact point, which can effectively ensure the anti-loosening performance of the fishhook. In addition, the angle between the main barb 2 and the main hook body 1 follows the conventional 30-45° angle. The appropriate barb angle design can avoid the situation where the fishhook comes off the hook due to the barb being too flat and the locking force being insufficient, and it can also avoid the situation where the barb tilt angle is too large, resulting in a sharp increase in resistance when penetrating or tearing of the fish mouth tissue after penetrating, leading to locking failure.

[0028] Considering that a single main barb is prone to coming off the hook due to force deviation when used on fish with large mouths, the anti-loosening hook disclosed in this embodiment further provides auxiliary barbs 6 symmetrically distributed on both sides of the main hook tip 5.

[0029] like Figure 3 As shown, cut surfaces 7 are formed on both sides of the main hook tip 5. The cut surfaces 7 provide a structural basis for the formation of the auxiliary barbs 6. The auxiliary barbs 6 are set at the cut surfaces 7. The angle between the auxiliary barbs 6 and the cut surfaces 7 is also a conventional 30-45° angle. This can form a sufficient reverse contact surface and avoid excessive penetration resistance, so as to achieve smooth penetration and effective locking.

[0030] The auxiliary barbs 6 on both sides of the main hook tip 5 can play an auxiliary role in preventing the hook from getting off when the main hook tip penetrates the fish's mouth tissue (such as the fish's lips or oral cavity). The small barbs on both sides can form a two-way anchor, which will respectively lock the surrounding tissue at the location where the main hook tip penetrates, disperse the pulling force when the fish struggles, and make the connection between the hook and the fish's mouth more secure. Especially when dealing with fish with large mouths and strong struggling force, it can effectively reduce the occurrence of hook getting off due to force deviation.

[0031] Furthermore, considering that large-mouthed fish (such as carp and grass carp) often swallow bait in large gulps, a wide hook gape can accommodate the wide mouth shape of these fish, ensuring the piercing effect of the main hook point 5 and the locking effect of the barb. Therefore, the anti-loosening hook disclosed in this embodiment adopts a wide gape design. Figure 2As shown, let the length of the main hook tip 5 be L_main hook tip, and let the gate width of the anti-loosening hook be W_hook gate, so that the gate width W_hook point is... 钩门 ≥ Main hook tip length L 主钩钩尖 1.5 times.

[0032] In addition, when using a fishhook, it needs to be connected to the fishing line. Usually, the hook shank of the main hook body 1 is used as the winding area 3, and a line loop 4 is integrally connected to the end of the main hook body 1 through the winding section 3.

[0033] To prevent the fishing line bound to segment 3 from moving up and down, such as Figure 2 and Figure 5 As shown, a limiting groove 31 is provided at the line winding section 3 of the hook shank. The limiting groove 31 occupies the semi-cylindrical part, and the limiting surface formed by the upper and lower parts resists the vertical movement of the fishing line. Furthermore, the groove surface of the limiting groove 31 is set as a rough surface 32, which can be made by a local sandblasting process. This increases the contact friction between the fishing line and the groove surface of the limiting groove 31, thereby further reducing the possibility of the fishing line moving up and down. It should be noted that the roughness Ra of the rough surface needs to be controlled between 1.6-3.2μm, so that the rough surface has the characteristics of shallow texture and rounded protrusion (such as the rough surface formed by knurling, whose protrusion radius is ≥0.02mm), so as to avoid unnecessary wear on the fishing line caused by the rough surface.

[0034] The 4-ring loop features a smooth, circular structure. The smooth ring has no sharp edges or burrs, preventing the fishing line from being cut by sharp edges when pulled or rubbed.

[0035] Furthermore, the anti-detachment fishhook disclosed in this embodiment is made of thickened carbon steel, which can withstand the strong pulling force when a large fish struggles, and prevent the hook bar from deforming or breaking.

[0036] In summary, the anti-get-out fishhook disclosed in this embodiment, based on the existing single-hook, single-barb fishhook structure, adds auxiliary barbs on both sides of the main hook tip. These auxiliary barbs enhance the anti-get-out function when the main hook tip pierces the fish's mouth tissue, forming a bidirectional anchoring effect, thus making the connection between the main hook tip and the pierced fish's mouth tissue more secure. Simultaneously, the multi-barb layout formed by the auxiliary barbs and the main barb increases the probability of hooking the fish, effectively reducing the probability of the fish getting off the hook. Furthermore, the design of the limiting groove combined with the rough surface effectively reduces the possibility of the fishing line moving up and down when it is wrapped around the hook shank, thereby ensuring the stability of the knot and further contributing to maintaining the anti-get-out performance of the fishhook in this embodiment.

[0037] Example 2

[0038] This embodiment discloses an anti-detachment fishhook, based on the fishhook structure disclosed in Embodiment 1, such as... Figure 4As shown, a sub-hook 8 is integrally connected at the bottom of the hook bend of the main hook body 1, and the sub-hook 8 is bent toward the hook shank.

[0039] like Figure 6 As shown, the sub-hook 8 also has a sharp sub-hook tip 9, and a sub-hook barb 10 is provided at the position of the sub-hook tip 9, and the sub-hook barb 10 is integrally connected to the sub-hook tip 9.

[0040] Since the large mouth swallows the bait in large gulps when feeding, the anti-loosening hook designed in this embodiment is further equipped with a sub-hook on the main hook body 1. The sub-hook works together with the main hook, which is the mother hook, to form a double piercing + locking effect, thereby improving the problem of low single hook catch rate and high risk of hooking off.

[0041] Furthermore, the tip of the sub-hook is also equipped with a barb to provide irreversible mechanical restraint after the hook tip penetrates, in order to maintain the effectiveness of the sub-hook 8.

[0042] In addition, to enhance the fish-attracting effect, the anti-loosening fish hook disclosed in this embodiment has a colored paint layer formed on the surface of both the main hook body 1 and the sub-hook 8. The colored paint layer can be achieved through processes such as electroplating, painting, electrophoresis and coating. Different processes correspond to different color types, which can be selected according to specific needs.

[0043] In summary, this utility model effectively improves the anti-fish-loosening performance of the fish hook through multiple structural designs such as auxiliary barbs, limiting grooves, and mother-daughter hooks.

[0044] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
