Abstract
Description
Technical Field
[0001] This application relates to fishing tools, and in particular to a double-line, double-hook fishing line. Background Technology
[0002] There are many fishing techniques, with traditional fishing and platform fishing being the most common. Traditional fishing uses a single line with a float and hook, employing a long rod and short line. The advantage is that the bite signal is very accurate, but the disadvantage is that the line is prone to breaking when encountering large fish, requiring a replacement of the line and wasting the float. Platform fishing uses a long main line with a short leader. The advantage is that using a suitable length of double hook leader can catch large fish, but the disadvantage is that the leader and main line are made of the same nylon material. If you want to increase the leader's tensile strength, increasing the line size will result in an overly thick line, causing the fish to bite and become unsuitable for the hook. If you want to increase the leader's palatability, decreasing the line size will result in a significant decrease in tensile strength, and due to knots, it will be much less than the hook's tensile strength, making the leader very easy to break.
[0003] Therefore, a double-hook leader that can withstand greater tension, has strong tensile strength, good palatability, is not easily hooked, and greatly reduces the amount of tangling on the leader line is better for platform fishing. Utility Model Content
[0004] Purpose of this utility model: The purpose of this application is to provide a double-line, double-hook leader for platform fishing, which, when used with a main line capable of withstanding significant tension, not only possesses strong tensile strength and good palatability, but also prevents easy hooking and greatly reduces leader tangling.
[0005] Technical solution: A double-line, double-hook leader for platform fishing, comprising a stiff line, a first soft line, a second soft line, a first hook, and a second hook. One end of the first soft line is connected to one end of the stiff line, and the other end of the first soft line is connected to the first hook. One end of the second soft line is connected to the other end of the stiff line, and the other end of the second soft line is connected to the second hook. The length of the first soft line is at least 1 mm longer than the length of the first hook, and the length of the second soft line is at least 1 mm longer than the length of the second hook.
[0006] After the main line is connected to the rigid line, the double-line, double-hook leader hangs freely. The connection point between the main line and the rigid line is such that the first hook is on top and the second hook is on the bottom. When the second soft line and the second hook are vertical, the end of the second hook is below the end of the first hook, and the vertical distance between the end of the second hook and the end of the first hook is not less than 0.5 cm. When the first soft line and the first hook are horizontal below the rigid line, the horizontal distance between the end of the first hook and the second soft line is not less than 1 cm. When the second soft line and the second hook are horizontal below the rigid line, the horizontal distance between the end of the second hook and the first soft line is not less than 1 cm.
[0007] Furthermore, the first soft line and the second soft line are of equal length, and the first fishhook and the second fishhook are of equal length.
[0008] Furthermore, the rigid thread is made of nylon or metal to meet the requirements for tensile strength and bifurcation, while the first and second soft threads are made of PE or carbon fiber to meet the requirements for tensile strength and palatability.
[0009] Furthermore, a branching structure is provided at the connection between the main line and the rigid line. The support length of the branching structure on the rigid line on one side is not less than 0.1cm, so that the branching structure can effectively branch the rigid lines on both sides.
[0010] Furthermore, protective sleeves are fitted at the joints of the first soft line and the hard line, and at the joints of the second soft line and the hard line, to enclose the knotted line ends and prevent the soft line or fishhook from being snagged by the exposed line ends; anti-abrasion sleeves are fitted on the shanks of the first and second fishhooks at the joints of the first soft line and the first fishhook, and at the joints of the second soft line and the second fishhook, to prevent the soft line from breaking due to direct friction when pulled with the hook shank.
[0011] Furthermore, the double-line, double-hook leader must meet the requirements for platform fishing pull strength. Therefore, the pull strength of the stiff line is not less than the pull strength of the first soft line and the second soft line, the pull strength of the first soft line is greater than the pull strength of the first hook, and the pull strength of the second soft line is greater than the pull strength of the second hook.
[0012] Furthermore, when using nylon line for the rigid line, considering the estimated remaining tensile strength after the nylon line knots, the following values are calculated: the tensile strength of the first hook is a kg, the tensile strength of the first soft line is at least 1.25 kg + a kg, the tensile strength of the rigid line is at least 2.5 kg + 2a kg, the tensile strength of the second hook is b kg, the tensile strength of the second soft line is at least 1.25 kg + b kg, and the tensile strength of the rigid line is at least 2.5 kg + 2b kg.
[0013] Beneficial effects: The double-line double-hook leader of this application uses a combination of hard and soft lines. When fishing, the hard line part has greater tensile strength and plays a supporting role in separating and dangling the leader, while the soft line part has good palatability for fish to bite and also has strong tensile strength. After the main line is connected to the hard line, the structural relationship between the hard line, soft line and fish hook when the double-line double-hook leader hangs freely has been tested for a long time. The overall tensile strength of the double-line double-hook leader is greatly improved, and the phenomenon of hooks and leaders tangling together is greatly reduced. Attached Figure Description

[0018] The present application will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art fall within the scope defined by the appended claims.
[0019] The double-line, double-hook leader of this application is a double-line, double-hook structure suitable for platform fishing, as shown in the attached document. Figure 1 As shown, it includes a hard wire 1 ( Figure 1 (shown in green), First soft line 2 ( Figure 1 (shown in red in the middle), second soft line 3 ( Figure 1 (shown in red in the middle), first hook 4 ( Figure 1 (shown in blue in the middle), second hook 5 ( Figure 1 (Shown in blue) One end of the first soft line 2 is connected to one end of the hard line 1, and the other end of the first soft line 2 is connected to the first hook 4. One end of the second soft line 3 is connected to the other end of the hard line 1, and the other end of the second soft line 3 is connected to the second hook 5. That is, a soft line is connected to each end of the hard line, and a hook is connected to each soft line. The hard line 1 is harder than the first soft line 2 and the second soft line 3. Therefore, the hard line 1 can be made of nylon or metal (such as copper wire), while the first soft line 2 and the second soft line 3 can be made of PE or carbon fiber.
[0020] The lengths of the first soft line 2 and the second soft line 3 can be equal or unequal. The lengths of the first hook 4 and the second hook 5 can be equal or unequal. The sum of the lengths of the first soft line 2 and the first hook 4 can be equal or unequal to the sum of the lengths of the second soft line 3 and the second hook 5. However, the length of the first soft line 2 must be at least 1 mm longer than the length of the first hook 4, and the length of the second soft line 3 must be at least 1 mm longer than the length of the second hook 5. The soft line being slightly longer than the hook is more palatable to the fish.
[0021] Combined with appendix Figure 1 , 2 As shown, the main line 8 is connected to the hard line 1 of the double-line double-hook sub-line. A branching structure 9 is set at the connection between the main line 8 and the hard line 1. The branching structure 9 can be a branching device or a method of making a flat pole line fork knot using the hard line. The branching structure 9 forms a support on one side of the hard line 1, and the support length L1 is not less than 0.1cm, so that the branching structure can effectively branch the hard lines on both sides.
[0022] Combined with appendix Figure 2 , 3 As shown in Figure 4, when the main line 8 is connected to the hard line 1 and the double-line double-hook leader hangs freely, the following three points must be met to significantly reduce the hook-hook phenomenon between the first and second hooks and the tangling phenomenon between the first and second soft lines:
[0023] The connection point between the main line 8 and the rigid line 1 makes the first hook 4 on top and the second hook 5 on the bottom, that is, the two hooks are at different heights.
[0024] With the connection point between the upper end of the second soft line 3 and the hard line 1, when the second soft line 3 and the second fish hook 5 are in a vertical position, the end of the second fish hook 5 is below the end of the first fish hook 4, and the vertical distance L2 between the end of the second fish hook 5 and the end of the first fish hook 4 is not less than 0.5cm.
[0025] When the first soft line 2 and the first fishhook 4 are horizontally positioned with their upper ends connected to the hard line 1, the horizontal distance L3 between the end of the first fishhook 4 and the second soft line 3 is not less than 1 cm. When the second soft line 3 and the second fishhook 5 are horizontally positioned with their upper ends connected to the hard line 1, the horizontal distance L4 between the end of the second fishhook 5 and the first soft line 2 is not less than 1 cm.
[0026] Protective sleeves 6 are fitted at the joints of the first soft line 2 and the hard line 1, and at the joints of the second soft line 3 and the hard line 1, to cover the knotted ends of both lines and prevent the soft line or hook from being snagged by the exposed ends. At the joints of the first soft line 2 and the first hook 4, and at the joints of the second soft line 3 and the second hook 5, anti-abrasion sleeves 7 are first fitted onto the shanks of the first hook 4 and the second hook 5, and then the soft line is knotted on the anti-abrasion sleeves. The anti-abrasion sleeves prevent the soft line from breaking due to direct friction when pulled on the hook shank.
[0027] The double-line, double-hook leader meets the pulling force requirements for platform fishing. The pulling force of the stiff line 1 should not be less than that of the first soft line 2 and the second soft line 3. When the pulling forces of the first soft line 2 and the second soft line 3 are unequal, the pulling force of the stiff line 1 should not be less than the larger pulling force. The pulling force of the first soft line 2 should be greater than that of the first hook 4, and the pulling force of the second soft line 3 should be greater than that of the second hook 5.
[0028] When using nylon line for the stiff line 1, knots in the nylon line will cause tensile loss. The remaining tensile strength after the knot needs to be estimated. In this case: Let the tensile strength of the first hook 4 be *a* kg, then the tensile strength of the first soft line 2 is at least 1.25 kg + *a* kg, and the tensile strength of the stiff line 1 is at least 2.5 kg + 2*a* kg. Let the tensile strength of the second hook 5 be *b* kg, then the tensile strength of the second soft line 3 is at least 1.25 kg + *b* kg, and the tensile strength of the stiff line 1 is at least 2.5 kg + 2*b* kg. When the tensile strengths of the first soft line 2 and the second soft line 3 are unequal, the tensile strength of the stiff line 1 should not be less than the larger tensile strength. The table below lists three examples of tensile strength combinations:
[0029]
[0030] The double-line, double-hook leader of this application uses a combination of stiff and soft lines. When fishing for large or small fish, the stiff line provides greater tensile strength and supports the dangling leader, while the soft line offers good palatability for fish bites and also provides strong tensile strength. After the main line is connected to the stiff line, the structural relationship between the stiff line, soft line, and hooks when the double-line, double-hook leader hangs freely is significantly improved through long-term testing. This also greatly reduces the phenomenon of hooks and leaders tangling together, such as the first hook hooking the second hook, the first soft line tangling with the second soft line, the first hook tangling with the second soft line, and the second hook tangling with the first soft line. These phenomena are all effectively avoided. Based on the above characteristics, the double-line double-hook leader of this application, without changing the current fishing habits of platform fishing enthusiasts, can be arbitrarily combined with the size of the hard line and the first soft line and the second soft line according to the size of the fish species. Such a double-line double-hook leader structure is also more easily accepted and used by the majority of fishing enthusiasts.
