Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIGS. 1-6, 1, the general structure of the fish hook of the present invention

The general structure of a traditional fishhook: the conventional fishhook is bent from the hook tip to a small diameter (as shown in the area of the dashed box 1 in fig. 1A), and then bent to a large diameter (as shown in the area of the dashed box 2 in fig. 1A) or to a nearly equal diameter (as shown in the area of the dashed box 3 to the dashed box 4 in fig. 1B). The hook tips point very close to the ends of the bar (as indicated by the direction of the hook tips indicated by arrow 10 in fig. 1A and by the direction of the hook tips indicated by arrow 11 in fig. 1B in relation to the respective bar ends). The catch of a conventional fishhook is mostly of a collapsed configuration (as shown in the area of dashed box 7 in fig. 1A and dashed box 8 in fig. 1B). The barbs are inward of the hook tip (as indicated by arrows 13 in fig. 1A and 14 in fig. 1B).

The overall structure of the fishhook of the invention is as follows: the fishhook of the invention starts from the hook tip to bend with a large diameter (as shown in the area of the broken frame 5 in fig. 1C), and then is converted into the small diameter to bend to the hook handle (as shown in the area of the broken frame 6 in fig. 1C), the hook tip is parallel to the hook handle (as shown in the direction of the hook tip indicated by the arrow 12 and the direction of the hook handle indicated by the arrow 16 in fig. 1C), the stop handle is a bent-back structure (as shown in the area of the broken frame 9 in fig. 1C), the end of the bent-back structure is a one-way inclined surface (as shown by the arrow 17 in fig. 1C) inclined towards the direction of the hook handle, and the barb is lateral to the hook surface (as shown in fig. 1D, the barb position indicated by the arrow 15 in the front longitudinal view of the fishhook of the invention).

2. The mechanical principle of the hook tip of the fishhook in the aspect of improving the penetration probability of the interior of a fishmouth

Traditional fishhook is in the inside probability of stabbing of fish mouth: because the inner wall of the fishmouth is parallel to the pulling force direction of the fishhook, and the hook tip of the traditional fishhook is very close to the hook handle because the hook tip points to, the hook tip is very close to and parallel to the inner wall of the fishmouth when the fishmouth is inside (as the angle between the hook tip direction indicated by

arrows

1 and 2 in fig. 2A and 2B and the inner wall of the fishmouth shown by a broken frame), the penetration probability of the hook tip of the traditional fishhook inside the fishmouth is very low, and the hook tip can only slide to the edge of the fishmouth to hook a fragile lip in most cases.

The direction of the hook tip of the fishhook of the invention is parallel to the direction of the hook handle, so that the hook tip has a proper penetrating angle (the angle relationship between the direction of the hook tip and the inner wall of the fishmouth shown by a broken frame as shown by an arrow 3 in fig. 2C) with the inner wall of the fishmouth when the hook tip is in the fishmouth, thereby leading the hook tip to have the highest penetrating probability in the fishmouth.

3. The principle of resistance change of the hook tip of the fishhook in the penetrating process after the fishhook is penetrated

Because the pull point of the fishline to the fishhook is positioned at the tail end of the hook handle, and the pull direction is always parallel to the inner wall in the fishmouth, the penetration process of the fishhook tip of the fishhook is also a process that the penetration attack angle of the fishhook tip gradually approaches to be parallel to the pull direction along with the depth increase (for example, in the process from 3A to 3B to 3C, the attack angle of the direction of the hook tip and the pull direction changes along with the penetration of the hook tip), and the penetration resistance of the fishhook tip is also a process that the penetration resistance gradually reduces, so the requirements of improving the penetration probability and reducing the penetration resistance in the penetration process are met at the same time.

4. The hook door stress structure principle of the fishhook

Analyzing the stress of a hook door of a traditional fishhook: because the hook point of the traditional fishhook is inclined towards the hook handle, when the hook point is inserted into the direction of the hook point and the direction of the tension line are consistent, the hook point cannot be continuously close to the inner side of the skin and the flesh, because at the moment, if the hook point is continuously close to the inner side of the skin and the flesh, the direction of the hook point and the direction of the tension line are directed to the outer side of the skin and the flesh and move to the outer side of the skin and the flesh (as shown by the angle relation between the direction of the hook point and the direction of the inner wall of the fishmouth shown by a broken frame in fig. 4B, an arrow 2 shows that the direction of the hook point and the direction of the inner wall of the fishmouth show by the broken frame). The position of the hook tip penetrating into the skin and meat is close to the position of the inner wall of the fish mouth, so that only a small amount of skin and meat can be hooked and only a small pulling force can be borne (such as the skin and meat accumulation part indicated by an arrow 5 in fig. 4A). And because the traditional fishhook is mainly stressed by the area near the hook tip (such as a hook door stress point shown by an arrow 4 in fig. 4A), and the hook tip is the weakest point of the fishhook, the structural strength of the hook door of the traditional fishhook is small.

The invention relates to a fishhook door stress analysis method, which comprises the following steps: the hook tip and the hook handle of the fishhook of the invention are parallel, the deep process of the hook tip is the process that the direction of the hook tip is consistent with the direction of the pulling force, so the direction of the hook tip is consistent with the direction of the pulling force (as shown in figure 4C) only when the hook handle is completely close to the inner wall of the fishmouth, as long as the hook handle is not completely close to the skin and meat inside the fishmouth, the direction of the hook tip still points to the inner side of the skin and continues to stab to the inner side, the inner part of the fishmouth can be hung on the most skin and meat by the hook door to bear the maximum pulling force, and as the pulling force action point of the fishhook is at the small-diameter bending point (as shown by an arrow 6 in figure 4C, the small-diameter hook bending stress area with the maximum structural strength in the hook door, and the direction of the hook tip is consistent with the direction of the pulling force at this time, the hook tip is not stressed transversely and is in the minimum state, therefore, the hook door of the fishhook can bear the maximum tensile force under the conditions of the same size, weight and material.

5. The invention relates to a retaining handle stress structure principle of a fishhook

The force analysis of the stop handle of the traditional fishhook is as follows: most conventional fishhooks of this kind have a flattened flat bar which is thin and slightly sharp and therefore prone to damage (e.g. sharp points indicated by arrows 1 in fig. 5A and 2, 3 in fig. 5B), so that the maximum tension that the line can withstand is much less than the tension limit of the line itself.

The invention relates to a fishhook stopper stress analysis: the fishhook stopper handle is a return bending structure, a fishline cannot exceed the stopper handle, and the part of the stopper handle for stopping the fishline is in an arc shape and does not damage the fishline (such as an arc stopping point indicated by an arrow 4 in fig. 5C), so that the maximum tensile force which can be borne by the fishline bound on the fishhook is closer to the tensile force limit value of the fishline per se. Meanwhile, the manufacturing process of the retaining handle of the return bending structure is simple, and compared with the retaining handle of the circular ring structure which is not easy to damage wires, the manufacturing process is simpler.

6. The invention relates to the principle of the inclined structure of the tail end of a stop handle of a fishhook

The one-way inclined surface (the structure indicated by the arrow 5 in fig. 5C) which inclines the tail end of the structure of the back bending retaining handle of the fish hook towards the direction of the hook handle is beneficial to completely penetrating earthworms and covering the retaining handle.

7. The barb structure principle of the fishhook of the invention

If the barb is positioned at the inner side of the hook tip for force analysis: if the barb is arranged on the inner side of the hook tip, the fishmouth skin flesh can be squeezed into the rear part of the barb during the penetration process of the fishhook, so that the fishmouth skin flesh has a good unhooking prevention function, but the additional resistance of the barb during the penetration process (the attack angle of the barb shown by an arrow 4 and the attack angle of the hook tip penetration direction shown by an arrow 1 in fig. 6A) is increased due to the larger attack angle of the barb and the hook tip penetration direction.

If the stress analysis of the barb outside the hook tip: if the barb is arranged on the outside, the barb does not function as a mousing hook because the barb is located at the opening where the jaw skin is pulled away by the hook (the position between the barb and the opening as shown by the arrow 5 in fig. 6B).

The barb stress analysis of the fishhook of the invention: the barb of the fishhook is arranged on the side surface of the hook tip (as shown in a front longitudinal view of the fishhook of the invention shown in figure 6C; the attack angle between the barb indicated by an arrow 6 and the penetration direction of the hook tip indicated by an arrow 3) so that the attack angle between the barb and the penetration direction of the hook tip is small, thereby reducing the additional resistance of the barb of the fishhook during the penetration process to the maximum extent and simultaneously not influencing the function of mousing-off prevention (as shown in a gap formed by pulling the skin and flesh of the fishmouth indicated by an arrow 7 of figure 6C away from the fishhook and a state that the skin and flesh of the fishmouth indicated by an arrow 8 of figure 6C are squeezed into the back part of the barb).

the invention has the comprehensive functions of high probability of the penetration of the hook tip in the fishmouth, small resistance of the hook tip penetrating into the skin and the flesh, complete penetration of the hook door and maximum hooking of the skin and the flesh of the fishmouth, maximum structural strength of the hook door and maximum bearing of tension, and maximum reduction of additional resistance of the fishhook in the penetration process on the premise of not influencing the unhooking prevention function due to the return bend stop handle and the ultimate tension of the fishline.
