Abstract
Description
Technical Field
[0001] This utility model relates to the field of fishing tackle technology, specifically to a knotless main line and a line rig using the knotless main line. Background Technology
[0002] Fishing requires tackle; conventional fishing methods include fishing rods, fishing lines, and bait. Fishing lines are typically composed of multiple lines with different purposes, such as the main line, leader, and tip line. The leader connects to the hook, the tip line connects to the rod, and the main line connects the leader and tip line, serving as the carrier for floats, sinkers, and other equipment; it is the longest and most important part of the tackle. Because fishing lines require different functions in different positions, using different materials to create tackle can meet various fishing needs while saving materials and reducing waste.
[0003] However, knots are required when connecting different lines in a fishing line rig. The strength of the fishing line is weakened at the knot, resulting in a loss of knot tensile strength and affecting the overall load-bearing capacity of the fishing line. At the same time, the line ends produced by the knot are also prone to tangling with other lines, further affecting the strength of the fishing line. Currently, there are some knotless mainlines that achieve knotless connection by threading the mainline through a hollow rope and wrapping it around a knotless buckle, or by using anti-tangle beads at the knot to prevent the line ends from tangling. However, the hollow ropes and anti-tangle beads in the existing technology are all bulky, which will generate greater water resistance and affect the posture of the fishing line when it enters the water. Utility Model Content
[0004] The purpose of this invention is to provide a knotless mainline that reduces knot tension loss and water resistance of the fishing line, as well as a line rig using the knotless mainline.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A knotless main line includes a main line with connecting structures at both ends. The connecting structures include a sleeve fitted over the outside of the main line. The end of the main line is folded in half and inserted into the sleeve. The folded part of the main line forms a folded section, and the part of the folded section extending out of the sleeve forms a connecting ring. The part of the folded section inside the sleeve forms a fixing section, which does not extend beyond the sleeve. The sleeve is filled with fixing adhesive.
[0006] Preferably, the sleeve is a flexible tube with openings at both ends.
[0007] A line rig using a knotless mainline includes a mainline, with a rod tip line and a leader line respectively connected to both ends of the mainline via a connecting structure; the connecting structure is connected to the leader line and the rod tip line via a connecting ring.
[0008] Preferably, a figure-eight loop is provided between the main line and the sub-line, with the two ends of the figure-eight loop connected to the connecting ring and the sub-line, respectively.
[0009] Preferably, the sleeve on the side of the main line closest to the rod tip rope extends to the outside of the connecting ring on the same side, and the space between the connecting ring and the sleeve is filled with fixing adhesive.
[0010] Preferably, the end of the rod tip rope is folded in half and passes through the connecting loop.
[0011] Preferably, multiple space beans are fitted on the outer side of the middle part of the main line, and a lead weight and a float are sandwiched between the multiple space beans.
[0012] The beneficial effects of this utility model are: This invention employs a folded main line passing through a sleeve to form a connecting loop structure for connecting the leader line and the rod tip line. Fixing adhesive is used to fill the inside of the sleeve to secure the folded structure at the end of the main line, achieving a knotless connection between the main line, leader line, and rod tip line. This effectively reduces knot tension loss in the main line and increases its tensile strength. Simultaneously, the absence of line ends prevents tangling. Compared to traditional knotless connection methods, the connection structure formed by this invention is smaller in size, has lower water resistance, increases the speed at which the fishing line enters the water, and effectively maintains the stability of the fishing line after it enters the water.

[0015] Example 1 The following is a further explanation of the present invention in conjunction with specific embodiments, such as... Figure 1 As shown, this embodiment is a knotless mainline, which mainly includes a mainline 1. Both ends of the mainline 1 are provided with connecting structures for connecting to the leader line and the rod tip rope.
[0016] The specific structure of the connection structure is as follows: Figure 2As shown, it includes a hollow sleeve 2 with openings at both ends, and the sleeve 2 is a flexible tube structure; the end of the main line 1 is folded in half and inserted into the sleeve 2, so that the folded part protrudes from the sleeve 2, and the fixed section of the folded part inside the sleeve 2 does not exceed the sleeve 2 to avoid forming a line end; the folded part of the main line 1 protruding from the sleeve 2 forms an annular connecting ring 3 structure, which can be used to connect with the leader line and the rod tip rope; the inside of the sleeve 2 is sealed with fixing glue to fix the connection between the main line 1 and the sleeve 2, and to prevent the main line 1 from sliding inside the sleeve 2 and causing the connection structure to come apart.
[0017] Multiple space bead 4 are also fitted on the main line 1, with a float seat 5 and a sinker 6 sandwiched between the space bead 4. The positions of the float seat 5 and the sinker 6 can be controlled by the space bead 4, and different space bead 4 can be used to measure water depth and other effects.
[0018] Example 2 This embodiment is a line group based on the knotless main line proposed in Embodiment 1, which includes a rod tip rope 10, a main line 1 and a leader line 8 connected in sequence; wherein, the main line 1 is connected to the leader line 8 and the rod tip rope 10 through the connection structures at both ends of its main line.
[0019] At one end of the main line 1 near the sinker 6, a figure-eight swivel 7 is connected via a connecting ring 3 structure; one end of the leader 8 is fixedly connected to the figure-eight swivel 7, and the other end is fixedly connected to a fishhook 9; at the other end of the main line 1, the rod tip rope 10 passes through the connecting ring 3 structure and is connected to the main line 1; in this embodiment, the sleeve 2 at the rod tip rope 10 moves upward to cover the connection between the rod tip rope 10 and the connecting ring 3, so that the connecting ring 3 is completely covered inside the sleeve 2 and fixed and sealed by adhesive.
[0020] In practical use, the main line 1 needs to be connected to the leader line 8 and the rod tip rope 10 respectively. The rod tip rope 10 passes through the connecting loop 3 formed by folding the main line 1, and the sleeve 2 is placed on the position of the connecting loop 3, and then sealed with fixing glue. The leader line 8 is indirectly connected to the main line 1 through a figure-eight swivel 7. The connecting loop 3 formed by folding the main line 1 passes through one end of the figure-eight swivel 7, and the remaining folded part of the main line 1 is sealed and fixed by the sleeve 2 and fixing glue. Then the leader line 8 passes through the other end of the figure-eight swivel 7 and is knotted for fixation. After that, the rod tip rope 10 is tied to the fishing rod, and it can be used for fishing. If the leader line 8 is worn out during use, there is no need to reset the connection structure of the main line 1. You only need to tie a new leader line 8 to the figure-eight swivel 7.

All descriptions made do not imply any limitation on the protection scope of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be determined by the protection scope of the claims.
