Description

Technical Field

[0001] This utility model relates to the field of fishing tackle structure, and in particular to a fastening structure for binding the main line and the rod tip. Background Technology

[0002] The "rod tip" of a fishing rod refers to the first and thinnest section, where the line is attached. The end of the rod tip usually has a knot formed by the tip rope or a retaining ball, used to securely connect it to the main line (fishing line). Currently, securing is mainly achieved through methods such as tightening the rope loop and tying knots. Traditionally, a connecting rope is used to connect the main line and the rod tip. During connection, one end of the connecting rope is tied to the main line using various common knotting methods, while the other end is fixedly connected to the rod tip. However, using knots has certain drawbacks. The main issue is that the fibers at the knot are forced to bend, twist, and compress against each other, increasing the contact area and creating an irregular contact pattern. This irregular contact generates uneven friction and stress. Under tension, due to the presence of friction and changes in stress, some fibers may not be able to fully utilize their strength to resist the tension, resulting in a decrease in tensile strength. Moreover, friction generates heat, and under repeated stress, the accumulation of heat will accelerate the aging and wear of the rope material.

[0003] For example, the Chinese utility model patent specification (publication number: CN221785081U) discloses a fishing line connection structure, which includes a connecting segment formed by bending the fishing line and a buffer sleeve together. The two sides of this connecting segment are a first bent end and a second bent end, respectively. The second bent end and the first bent end have a first knot and a second knot. Although this connection structure eliminates the traditional rod tip rope, the first and second knots still exhibit uneven friction and stress as mentioned above, which can lead to reduced tensile strength, as well as material aging and wear.

[0004] In view of this, the inventor, drawing on years of experience in the field of fishing tackle, designed and optimized the product's structure, and after numerous trials and improvements, created this invention. Summary of the Invention

[0005] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a fastening structure for binding the main line and the rod tip that improves the tensile strength and achieves knotless connection.

[0006] To achieve the above objectives, this utility model provides a fastening structure for binding a main line and a rod tip, comprising: a main line and a hollow tube. The upper end of the main line passes through the hollow tube, so that the hollow tube is fitted onto the main line, and a knot is formed at the upper end as a limiting knot to prevent the main line from being pulled out of the hollow tube. The hollow tube has a bent rope loop at one end of the limiting knot and a closed portion formed by the end of the hollow tube adhering to the tube body. The closed portion has a knotless binding part formed by the connecting rope, and the rope loop can be adjusted by pushing the knotless binding part to adjust its size. At the same time, the head of the connecting rope passes through the rope loop and connects to its own tail to form a closed rope loop. The rope loop is tightened by the knotless binding part, so that the rope loop and the connecting rope are tightly connected together.

[0007] This utility model further provides a fastening structure for binding the main line and the rod tip, wherein a locking bead is also fitted on the rope loop for interference sliding.

[0008] This utility model further provides a fastening structure for binding the main line and the rod tip, wherein the hollow tube is a braided rope.

[0009] Compared to existing technologies, this invention combines a main line with a hollow tube, forming a retractable loop at the end where they connect to the rod tip (i.e., the upper end). Simultaneously, a knotless binding section is formed at the closed portion of the loop using a connecting rope, serving as an adjustment structure for tightening the loop. The head of the connecting rope passes through the loop and connects to its own tail, forming a loop for connection to the rod tip. Through the tightening operation of the knotless binding section and the traction of the connecting rope, the connecting rope and the loop are tightly connected, forming a tension point, causing the tension of the connecting rope, main line, and hollow tube to tend towards a straight line. However, this straight tension is uniformly distributed along the rope's axis. When the main line and connecting rope bear tension, the stress is also basically uniformly distributed across the cross-section. That is, in a straight line state, the fibers are basically parallel, resulting in more uniform stress and a relatively stable tension value, enabling it to withstand higher tension. This structure reduces knots and wear between the main line and connecting rope, while also aligning the tension of the main line and connecting rope more linearly, thus increasing the tensile strength. Furthermore, the connecting rope features a loop design, forming two parallel ropes that offer better load-bearing capacity and facilitate easier connection to the rod tip.

[0013] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0014] like Figure 1 , Figure 2 As shown, this embodiment provides a fastening structure for binding the main line and the rod tip. This fastening structure mainly includes a main line 1 (as the fishing line), a hollow tube 2, and a connecting rope 7. Common materials for the main line include nylon, carbon fiber, PE, and fluorocarbon fiber. In this embodiment, the main line can be any of the aforementioned materials. The lower end of the main line is used to connect to a fishing hook or various fishing line assemblies, such as platform fishing assemblies, multi-hook assemblies, and silver carp / bighead carp fishing assemblies. The upper end of the main line is used to connect to the rod tip of the fishing rod. To protect this connection from wear and enhance its strength, the hollow tube 2 is fitted onto the upper end of the main line 1, thus forming a connecting section. When the main line is connected to the hollow tube, the upper end of the main line passes through the hollow tube, and a knot is tied and the end is treated to create a knot as a limiting knot 3, preventing and restricting the main line from being pulled out of the hollow tube. At one end of the hollow tube located at the limiting knot (i.e., the upper end of the connecting section), a loop 5 is formed by bending the loop, and a closed portion is formed by this end adhering to the hollow tube body. This closed portion is wound several times with a connecting rope 7, forming a knotless binding part 4. Then, the head of the connecting rope used for winding passes through the loop set in the connecting section and connects with its own tail, thus forming a closed loop 6. The closure is mainly achieved by tying the head and tail together. The loop 6 forms two parallel ropes, which helps to enhance the load-bearing capacity of the connecting rope. The knotless binding part can be moved on the connecting section to adjust the size of the loop. When the head of the connecting rope passes through the loop, the loop is simultaneously tightened through the knotless binding part, making the loop and the connecting rope tightly connected together, forming a tension point, thus making the tension between the connecting rope and the main line tend to be linear. In addition, knotless binding also has the function of narrowing the inner hole of the hollow tube, which, together with the limiting knot, restricts the main line from being pulled out of the hollow tube, thus strengthening the stability of the connection between the two.

[0015] The aforementioned rope loop 6 can be connected to the knot head or stop ball of the rod tip using various knotting methods, such as a figure-eight knot (also known as a figure-eight rope knot, double figure-eight knot, or figure-eight rope loop), a double overhand knot, or other tightening loop tying methods. To facilitate the installation and removal of the rope loop from the rod tip, a locking bead 8 is also provided on the rope loop 6. This locking bead slides on the rope loop with an interference fit. The function of the locking bead is to tighten the various retractable small coils or loops formed by the rope loop for connecting the knot head or stop ball of the rod tip through sliding.

[0016] For example: Simply slip the rope loop over the knot at the rod tip and then slide the locking bead to tighten the loop. This method is suitable for fishing small fish. Alternatively, fold the rope loop into a double loop, overlap them to form a small, tightenable loop, slip this loop over the knot at the rod tip, pull the line tight, and finally lock the tightened double loop with the locking bead. This method is suitable for fishing large fish. Another method is to wrap the connecting rope around the rod tip rope once, then pass the knot of the rod tip rope through the loop of the connecting rope, pull the line tight, and finally lock it with the locking bead. This method is suitable for fishing very large fish. All three methods allow for quick installation and removal of the rod tip rope and rod tip.

[0017] The hollow tube 2 is achieved using a braided rope structure, which is a hollow rope woven from multiple strands of fibers or metal wires. This hollow tube not only possesses high strength and good flexibility, but also excellent wear resistance.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
