Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

Please refer to Figure 1-6, 1, the overall structure of the hook of the present invention

The overall structure of the traditional fish hook: the traditional fish hook is bent from the hook tip with a small diameter (as shown in the area of the dashed box 1 in Figure 1A), and then bent with a large diameter to the hook handle (in the area of the dashed box 2 in Figure 1A ) shown), or close to the equal diameter bending transformation (shown in the area of dashed box 3 to dashed box 4 in FIG. 1B). The hook tip points very close to the end of the stopper (the direction of the hook tip indicated by arrow 10 in FIG. 1A and the direction of the hook tip indicated by arrow 11 in FIG. 1B in relation to the end of the respective stopper). Most of the stoppers of traditional fish hooks are of a flattened structure (as shown in the area of the dashed box 7 in FIG. 1A and the dashed box 8 in FIG. 1B ). The barb is the medial side of the hook tip (the structural location indicated by arrow 13 in FIG. 1A and arrow 14 in FIG. 1B ).

The overall structure of the hook of the present invention: the hook of the present invention is bent from the hook tip with a large diameter (as shown in the area of phantom frame 5 in Fig. 1C ), and then converted to a small diameter and bent to the hook handle (as shown in the phantom in Fig. 1C ) shown in the area of frame 6), the hook tip is parallel to the hook handle (the direction of the hook tip indicated by the arrow 12 in Fig. 1C and the direction of the hook handle indicated by the arrow 16), and the handle is a back-bending structure (the phantom in Fig. 1C). As shown in the area of frame 9), the end of the back-bending structure is a unidirectional slope inclined to the direction of the hook handle (as indicated by the arrow 17 in Figure 1C), and the barb is the side of the hook surface (as shown in Figure 1D of the fish of the present invention). The barb position indicated by arrow 15 in the longitudinal view of the front of the hook).

2. The mechanical principle of the hook tip of the fish hook of the present invention in improving the probability of piercing inside the fish mouth

The penetration probability of the traditional fish hook inside the fish mouth: Since the inner wall of the fish mouth is parallel to the pulling force of the fish hook, and the traditional fish hook has the hook tip pointing very close to the hook handle, the hook tip is inside the fish mouth and the fish mouth when the hook tip is inside the fish mouth. The inner wall is very close to parallel (the direction of the hook tip indicated by arrows 1 and 2 in Figure 2A and Figure 2B and the angle of the inner wall of the fish mouth shown by the dashed box), so that the hook tip of the traditional fish hook has the probability of piercing inside the fish mouth. Very low, in most cases only slides to the edge of the mouth to hook the fragile lip.

The hook tip of the fish hook of the present invention is parallel to the direction of the hook handle, so the hook tip has a suitable penetration angle with the inner wall of the fish mouth when it is inside the fish mouth (as shown by arrow 3 in FIG. 2C , the direction of the hook tip and the virtual frame are The angle relationship of the inner wall of the fish mouth is shown), so that the hook tip has the highest penetration probability inside the fish mouth.

3. The principle of resistance change of the hook tip of the hook of the present invention during the penetration process after piercing

Since the pulling force point of the fishing line to the hook is at the end of the hook handle, and the pulling force direction is always parallel to the inner wall of the fish mouth, the in-depth process of the hook tip of the fish hook of the present invention after piercing is also the penetration of the hook tip. The process in which the angle gradually becomes parallel to the direction of the pulling force with the deepening of the depth (as shown in the process from 3A to 3B to 3C, the angle of attack between the direction of the hook tip and the direction of the pulling force changes with the depth of the hook tip), Therefore, it is also a process in which the piercing resistance of the hook tip is gradually reduced, so the requirements of improving the piercing probability and reducing the piercing resistance during the penetration process are achieved at the same time.

4. The force structure principle of the hook door of the fish hook of the present invention

Analysis of the force of the hook door of the traditional fish hook: Since the traditional fish hook is a structure in which the hook tip is inclined to the hook handle, when the hook tip penetrates into the direction of the hook tip and the tension line, it is impossible for the hook tip to continue to lean against the skin. The inner side, because if the hook tip continues to move toward the inner side of the flesh at this time, the direction of the hook tip and the direction of the tension line will point to the outside of the flesh and move to the outside of the flesh (as shown by arrow 2 in Figure 4B, the direction of the hook tip and the virtual The angular relationship of the direction of the inner wall of the fish mouth shown in the box). At this time, the position where the hook tip penetrates into the flesh is very close to the inner wall of the fish mouth, so it can only hook a small amount of flesh and can only bear a small pulling force (the place where the flesh accumulates as indicated by arrow 5 in Figure 4A). And because the traditional fish hook is mainly stressed by the area near the hook tip (the stress point of the hook door shown by arrow 4 in Figure 4A), and the hook tip is the thinnest and weakest point of the hook, the hook door of the traditional fish hook is of less structural strength.

The force analysis of the hook door of the hook of the present invention: the hook tip of the hook of the present invention and the hook handle are parallel, and the in-depth process of the hook tip is also a process in which the direction of the hook tip and the direction of the pulling force tend to be consistent, so the hook of the present invention is only in the When the hook handle is completely close to the inner wall of the fish mouth, the direction of the hook tip will be consistent with the direction of the pulling force (as shown in Figure 4C), because as long as the hook handle is not completely close to the skin inside the fish mouth, the direction of the hook tip will be the same. It still points to the inside of the flesh and continues to stab to the inside, so the inside of the fish mouth can be hung by the hook door with the most flesh and bear the maximum pulling force, and because the pulling force of the fish hook acts on the small-diameter bending point at the bottom of the hook handle (such as The stress area of the small-diameter hook shown by arrow 6 in Figure 4C), which is the part with the greatest structural strength in the hook door, and since the direction of the hook tip is consistent with the direction of the pulling force at this time, the hook tip is no longer affected at this time. Therefore, the hook door of this fish hook can bear the largest pulling force under the same size, weight and material conditions.

5. The principle of the force-bearing structure of the hook of the present invention

Analysis of the force on the handle of traditional fish hooks: Most types of traditional fish hooks have a flat handle that is flattened. The flat handle is slightly sharp because of its thinness, so it is easy to damage the line (arrow 1 in Figure 5A). and the sharp points indicated by arrows 2 and 3 in FIG. 5B ), so that the maximum pulling force that the fishing line can bear is much smaller than the limit value of the pulling force of the fishing line itself.

Analysis of the force of the catch handle of the fish hook of the present invention: The catch handle of the fish hook of the present invention is a kind of back-bending structure, the fishing line cannot go over the catch handle, and the part where the catch handle blocks the fishing line does not hurt the line because of the arc shape. (the arc blocking point indicated by arrow 4 in FIG. 5C ), therefore, the maximum tensile force that the fishing line bound on the fishing hook of the present invention can bear is closer to the limit value of the pulling force of the fishing line itself. At the same time, the handle of the back-bending structure has a simple manufacturing process, and has a simpler manufacturing process than the handle of the ring structure that is also less prone to wire damage.

6. The principle of the inclined structure of the end of the stopper of the hook of the present invention

The unidirectional slope (the structure indicated by arrow 5 in Fig. 5C ) of the back-bending stop structure of the fish hook of the present invention is beneficial to completely penetrate the earthworm and cover the stop.

7. The principle of the barb structure of the hook of the present invention

If the barb is placed on the inner side of the hook tip, the force analysis: if the barb is arranged on the inner side of the hook tip, during the piercing process of the fish hook, the flesh of the fish mouth will squeeze into the back of the barb and have a good anti-decoupling. But it will increase the additional resistance of the barb during the piercing process due to the larger angle of attack between the barb and the hook tip (the barb shown by arrow 4 in Figure 6A and the hook shown by arrow 1 in Figure 6A). angle of attack in the direction of penetration of the spike).

If the barb is placed on the outside of the hook tip, the force analysis: if the barb is placed on the outside, the barb will not be able to prevent de-hook because the barb is at the gap where the flesh of the fish mouth is pulled by the hook (as shown in Figure 6B). The position between the barb and the notch indicated by the arrow 5 in the middle).

The force analysis of the barbs of the hook of the present invention: the barbs of the hook of the present invention are arranged on the side of the hook tip (the front longitudinal view of the hook of the present invention as shown in FIG. 6C ; the barbs indicated by arrow 6 and arrow 3 Refers to the angle of attack of the hook tip in the piercing direction), so that the angle of attack between the barb and the hook tip piercing direction is very small, thereby minimizing the additional resistance of the barb during the piercing process of the hook without affecting the The function of preventing decoupling (as indicated by arrow 7 in Figure 6C, the fish mouth skin and flesh are pulled open by the fish hook, and the state where the fish mouth flesh is squeezed into the back of the barb indicated by arrow 8 in Figure 6C).

To sum up, the invention has the advantages of high probability of hook tip piercing in the fish mouth, low resistance of the hook tip penetrating into the skin and flesh, the hook door can completely penetrate deep into the fish mouth skin and the most meat, and the hook door has the greatest structural strength and can withstand the maximum amount of fish. The comprehensive pulling force and return-bending stopper of the fishing line can maximize the ultimate pulling force of the fishing line, and the barbs can minimize the additional resistance of the fishing hook during the piercing process without affecting the function of preventing decoupling. Function.

Compared with the prior art, the fish hook provided by the present invention has the following advantages:

The invention has the advantages of high probability of the hook tip piercing in the fish mouth, low resistance of the hook tip penetrating into the skin and flesh, the hook door can completely penetrate deep into the fish mouth skin and the most flesh, the hook door has the greatest structural strength and can bear the greatest pulling force, The back-bend stopper can maximize the ultimate tension of the fishing line, and the barb can minimize the additional resistance of the hook during the piercing process without affecting the function of preventing decoupling.
