Description

Technical Field

[0001] This utility model relates to the field of lure fishing hooks, specifically to an obtuse angle hook. Background Technology

[0002] Lure fishing primarily targets predatory fish in freshwater or saltwater using artificial lures. Its unique fishing method is often referred to as "water golf." Depending on the occasion, fish species, and fishing conditions, appropriate lures (including but not limited to jig heads, minnows, VIBs, spinners, noodle worms, Texas rigs, Caro rigs, etc.) need to be selected.

[0003] Among them, jig head hooks paired with soft baits account for most occasions of lure fishing. By choosing different weights, retrieval speeds, and bait control, different water depths can be searched.

[0004] Jig head fishing can be further subdivided into ordinary jig head hooks (horizontal hook body), NED jig head hooks (vertical hook body), and obtuse angle jig head hooks (slanted hook body).

[0005] To ensure the hook body is tilted upwards, or to allow it to quickly return to its original position if it tilts, the bottom of the weight block (lead block) is often curved when the hook body is tilted upwards. This lowers the center of gravity and, when used with a floating soft bait, provides upward traction to the hook body, allowing it to maintain the correct posture on the bottom like a roly-poly toy. By constantly jumping off the bottom, it simulates small fish and is used for fishing bottom-dwelling predatory fish (such as mandarin fish).

[0006] However, the existing obtuse angle jig head hooks have a counterweight (lead block) with a curved or spindle-shaped bottom surface, so the overall mass of the counterweight (lead block) cannot be reduced to the minimum. At the same time, the curved or spindle-shaped surface initially makes point contact or line contact when touching the bottom and then gradually sinks in, resulting in a blurred bottom contact sensitivity. Also, after sinking in, it can easily affect the correction of the hook body posture by the floating soft bait. Utility Model Content

[0007] Based on the above problems, the purpose of this utility model is to provide an obtuse angle hook that can effectively improve the bottom contact sensitivity and further lower the center of gravity, providing the necessary conditions for the floating soft bait to correct the hook body posture, while effectively avoiding or reducing the tipping of the hook body, reducing resistance and achieving the anti-snagging effect.

[0008] To address the above problems, the following technical solution is provided: an obtuse-angle hook, comprising a hook body and a counterweight. The hook body includes an inclined hook body, and a binding line segment is provided at the downward-inclined end of the hook body, which is at an angle to the hook body axis. The binding line segment has a binding line loop. The upward-inclined end of the hook body bends upward and forms a hook gate and hook tip facing the binding line segment. The counterweight is fixed at the junction of the hook body and the binding line segment. The counterweight extends downward, and its outer contour gradually increases, forming a horizontal contact plane on the bottom surface of the counterweight. The virtual contour formed by the contact plane and the horizontal slices of the counterweight at any position in the height direction is oval, egg-shaped, teardrop-shaped, or rhomboid. The long axis of the outer contour of the contact plane is parallel to or / and coincides with the virtual axis of the hook body projected onto the contact plane.

[0009] The present invention is further configured such that the degree of change in the arc radius of the contact plane corresponding to the side of the hook body tilting upward is less than the degree of change in the arc radius of the side of the hook body tilting downward.

[0010] The present invention is further configured such that, while the counterweight extends downward, the increasing speed of the outer contour of the side of the hook body that is inclined upward is greater than the increasing speed of the outer contour of the sides thereon or / and greater than the increasing speed of the outer contour of the side of the hook body that is inclined downward.

[0011] The present invention is further configured such that, while the counterweight extends downward, the outer contour of the side of the hook body that is tilted upward increases in three ways in sequence, forming an upward contour in the vertical direction, namely, slow, fast, and slow.

[0012] The present invention is further configured such that, as the counterweight extends downward, the outer contour of the side of the hook body that is tilted downward increases in three ways in sequence, forming an upper contour in the vertical direction: fast, slow, and fast.

[0013] The present invention is further configured such that an anti-disengagement hook is provided near the counterweight of the hook body; the anti-disengagement hook is formed by stamping on the hook body; or it is an independent unit fixed to the hook body by the counterweight; or a reinforcing sleeve is integrally connected to the counterweight, covering the outer wall of the hook body and extending towards the upward end of the hook body, and the anti-disengagement hook and the reinforcing sleeve are integrally formed and connected.

[0014] The present invention is further configured such that the anti-detachment hook is located at the 12 o'clock or 6 o'clock position on the cross-section of the hook body.

[0015] The present invention is further configured such that the included angle between the hook body and the contact plane is 25 degrees to 45 degrees.

[0016] The present invention is further configured such that the included angle between the hook body and the binding line segment is 60 degrees to 180 degrees.

[0017] The present invention is further configured such that the counterweight is made of lead, lead alloy, or tungsten alloy.

[0018] The beneficial effects of this utility model are:

[0019] 1. The counterweight extends downwards, its outer contour gradually increasing, and forms a horizontal contact plane on the bottom surface of the counterweight to ensure the contact area at the bottom, improve the bottoming sensitivity, and avoid or reduce sinking.

[0020] 2. It can reduce most of the mass of the counterweight as much as possible, reducing or avoiding the possibility of tipping over. Even if tipping occurs, the low center of gravity can help the floating soft bait correct the hook's posture.

[0021] 3. The virtual outline formed by the horizontal slices of the contact plane and the counterweight at any position in the height direction is oval, egg-shaped or teardrop-shaped, which can effectively reduce casting resistance and recovery resistance after entering the water, reduce turbulence and improve sensitivity, make the swimming action of the floating soft bait more realistic when jumping to the bottom or recovering, and further reduce the risk of snagging on the bottom.

[0022] 4. By adjusting the speed of contour change, the center of gravity of the counterweight is lowered while a larger portion of the mass is shifted to the rear of the hook (i.e., the center of gravity is further back in the recovery direction), which helps to ensure the overall stability during recovery and avoids unnecessary swaying due to the center of gravity being forward.

[0023] 5. Control the increase in height to help lower the center of gravity of the counterweight while maintaining its streamlined shape;

[0024] 6. The counterweight is positioned at the foremost point of the hook body on the downward-sloping side, in the direction of line take-up. When encountering obstacles, it can act as a fulcrum to lift the hook body in time and prevent it from getting snagged on the bottom. Attached Figure Description

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0036] refer to Figures 1 to 9 ,like Figures 1 to 9 An obtuse-angle hook is shown, comprising a hook body 10 and a counterweight 20. The hook body 10 includes an inclined hook body 11. A binding line segment 12 is provided at the downward inclined end of the hook body 11, which is at an angle to the axis of the hook body 11. The binding line segment 12 is provided with a binding line loop 121. The upward inclined end of the hook body 11 is curved upward to form a hook gate 13 and a hook tip 14 facing the binding line segment 12. The hook tip 14 may be provided with barbs (not shown in the figure) as needed. The counterweight 20 is fixed at the junction of the hook body 11 and the binding line segment 12. The counterweight 20 extends downward, and its outer contour gradually increases, forming a horizontal contact plane 21 on the bottom surface of the counterweight 20. The virtual contours formed by the horizontal slices of the contact plane 21 and the counterweight 20 at any position in the height direction are all oval, egg-shaped, teardrop-shaped, or rhomboid. The long axis of the outer contour of the contact plane 21 is parallel to or / and coincides with the virtual axis of the hook body 11 projected onto the contact plane 21.

[0037] In the above structure, the counterweight 20 extends downwards, its outer contour gradually increasing, and a horizontal contact plane 21 is formed on the bottom surface of the counterweight 20. This ensures a large contact area at the bottom, improves bottom contact sensitivity, and avoids or reduces sinking. At the same time, it allows most of the mass of the counterweight 20 to be reduced as much as possible, reducing or avoiding the possibility of tipping over. Even if tipping occurs, the low center of gravity can help the floating soft bait correct the posture of the hook body 11. The virtual contours formed by the contact plane 21 and the horizontal slices of the counterweight 20 at any position in the height direction are all oval, egg-shaped, or teardrop-shaped. This can effectively reduce casting resistance and recovery resistance after entering the water, reduce turbulence and improve sensitivity. When jumping to the bottom or recovering, it makes the swimming action of the floating soft bait more realistic and further reduces the risk of snagging.

[0038] In this embodiment, the degree of drastic change in the arc curvature of the contact plane 21 corresponding to the upward-sloping side of the hook body 11 is less than the degree of drastic change in the arc curvature of the downward-sloping side of the hook body 11.

[0039] In the above structure, the resistance of the counterweight 20 on the water-facing surface in the recovery direction is reduced, making the movement of the counterweight 20 and the hook 10 more stable.

[0040] In this embodiment, as the counterweight 20 extends downward, the rate of increase of its outer contour on the side of the hook body 11 that is tilted upward is greater than the rate of increase of its outer contour on both sides and / or greater than the rate of increase of its outer contour on the side of the hook body 11 that is tilted downward.

[0041] In the above structure, by adjusting the speed of contour change, the center of gravity of the counterweight 20 is lowered while a larger portion of its mass is shifted to the rear of the hook body 11 (i.e., the center of gravity is shifted to the rear in the recovery direction), which helps to ensure the overall stability during recovery and avoids unnecessary swaying due to the center of gravity being shifted to the front.

[0042] In this embodiment, as the counterweight 20 extends downward, its outer contour corresponding to the upward-sloping side of the hook body 11 increases in three ways—slow, fast, and slow—to form an upward contour in the vertical direction.

[0043] In the above structure, the increase in height is controlled to help lower the center of gravity of the counterweight 20 while maintaining its streamlined shape.

[0044] In this embodiment, as the counterweight 20 extends downward, its outer contour corresponding to the downward-sloping side of the hook body 11 increases in three ways—fast, slow, and fast—to form an upward contour in the vertical direction.

[0045] In the above structure, the counterweight 20 is positioned at the foremost point of the contact plane 21 on the downward tilting side of the hook body 11 in the line take-up direction. When encountering an obstacle, it can act as a fulcrum to lift the hook body 10 in time to avoid snagging on the bottom.

[0046] In this embodiment, the hook body 10 is provided with an anti-detachment hook 22 near the counterweight block 20; the anti-detachment hook is formed by stamping on the hook body 10 (not shown in the figure); or it is an independent unit that is fixed to the hook body 10 by the counterweight block 20 (not shown in the figure); or a reinforcing sleeve 23 is integrally connected to the counterweight block 20, covering the outer wall of the hook body 11 and extending towards the upward end of the hook body 11, and the anti-detachment hook 22 and the reinforcing sleeve 23 are integrally formed and connected.

[0047] In the above structure, the anti-detachment hook 22 is used to help fix the soft bait and prevent it from being pulled out or slipping out when casting or when a fish bites.

[0048] In this embodiment, the anti-detachment hook 22 is located at the 12 o'clock or 6 o'clock position on the cross-section of the hook body 11.

[0049] In the above structure, when the anti-derailment hook is formed by stamping on the hook body 10 (not shown in the figure), it is preferably located at the 12 o'clock or 6 o'clock position of the cross-section of the hook body 11; when the anti-derailment hook is an independent individual (not shown in the figure), it is preferably located at the 6 o'clock position of the cross-section of the hook body 11; when the anti-derailment hook 22 is provided by the reinforcing sleeve 23, it is preferably located at the 12 o'clock position of the cross-section of the hook body 11.

[0050] In this embodiment, the included angle a1 between the hook body 11 and the contact plane 21 is 25 degrees to 45 degrees.

[0051] In the above structure, the included angle α1 between the hook body 11 and the contact plane 21 is preferably one of 11 integers between 30 degrees and 40 degrees.

[0052] In this embodiment, the included angle a2 between the hook body 11 and the binding line segment 12 is 60 degrees to 180 degrees.

[0053] In the above structure, the included angle a2 between the hook body 11 and the binding line segment 12 is preferably one of 11 integers between 120 degrees and 130 degrees.

[0054] In this embodiment, the counterweight 20 is made of lead, lead alloy, or tungsten alloy.
