AI Technical Summary
The existing mainline connection structure lacks an effective means to limit the sliding stroke of the locking bead, which makes the locking bead prone to slipping when not in use, affecting the stability and safety of the mainline connection.
A raised structure is set on the outer surface of the main line protection rope, and a mechanical limit is formed by using an elastic sleeve or rubber material to restrict the downward path of the locking bead and ensure that it does not detach from the hollow protection rope.
It effectively prevents the locking bead from slipping out, maintains the stability and safety of the main line connection, and avoids the locking bead from accidentally coming off when not in use.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fishing tackle, specifically to an anti-slip structure for preventing the main line locking bead from slipping off. Background Technology
[0002] In daily fishing, the main line is usually fixed to the tip of the fishing rod by tying a knot. To enhance the structural stability of the knot, a hollow protective rope is often put on the knot and a locking bead is used to limit it, thereby preventing the main line from coming loose.
[0003] However, in actual use, when it is necessary to loosen the locking bead, if its movement exceeds the length of the hollow protective rope, the locking bead is very easy to slip off the protective rope. After it is removed from the protective rope, it is not only difficult to re-attach, but it may also cause the knot of the main line to loosen because it cannot effectively limit the knot.
[0004] The existing mainline connection structure lacks an effective means to limit the sliding stroke of the locking bead, and cannot prevent it from slipping out unexpectedly when not in operation. Utility Model Content
[0005] The purpose of this invention is to provide an anti-slip structure for preventing the main line locking bean from slipping out, so as to solve the problem that the existing main line connection structure lacks an effective means to limit the sliding stroke of the locking bean, and cannot prevent it from slipping out unexpectedly when not in operation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An anti-slip structure for preventing the mainline locking bead from slipping off is provided. The anti-slip structure is disposed on the outer surface of the mainline protection rope, which covers a section of the upper end of the mainline. The upper end of the mainline is fixed to the rod tip of the fishing rod by a knot. The locking bead is sleeved on the mainline protection rope and is used to limit the knot position. The anti-slip structure is a protrusion structure disposed below the locking bead, which protrudes above the surface of the protection rope and is used to mechanically limit the locking bead.
[0008] The protruding structure is a section of elastic sleeve with a protruding part in the middle. The elastic sleeve is made of rubber, silicone or heat-shrinkable material.
[0009] The raised structure is fixed to the surface of the cable by an adhesive, which is a pressure-sensitive adhesive, hot melt adhesive, or instant adhesive.
[0010] The raised structure is formed by heat shrinking, injection molding, winding or molding.
[0011] The raised structure is formed by dripping a curable adhesive material onto the surface of the cable and then curing it. The adhesive material can be an instant adhesive, epoxy resin, hot melt adhesive, UV curable adhesive, or liquid silicone.
[0012] This invention effectively prevents the locking bead from sliding down the line protection rope. During fishing, even if the locking bead is opened to create distance, the device can ensure that the locking bead will not detach from the hollow line protection rope, thus effectively limiting the locking bead and maintaining the stability and safety of the main line connection. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0014] The present invention will be further described below with reference to its actual structure:
[0015] The main fishing line 1 has a main line protection rope 2 near its upper end. This protection rope wraps around the main line to provide flexible protection and structural connection. The main line is fixed to the rod tip 3 of the fishing rod by knotting, while the locking bead 4 is fitted on the outside of the main line protection rope to limit the knot position 5.
[0016] To prevent the locking bead from slipping and dislodging along the main line protection rope when the knot is loosened, a protruding structure 6 is provided below the locking bead 4 outside the main line protection rope. This protruding structure 6 can be implemented in the following ways:
[0017] Heat shrink tubing bulge type: Heat shrink material is used to cover the outside of the protective rope. Local heating causes insufficient shrinkage in the middle or expansion of the inner filling material, forming an outer bulge, which constitutes a limiting stop.
[0018] Adhesive bonding type: A pre-made hemispherical or ring-shaped adhesive object is bonded to the outside of the protective rope, and a protrusion is formed by fixing it with adhesive (at room temperature or hot melt).
[0019] Wrapping type: Rubber thread, elastic band or other flexible strip material is wrapped around the outside of the protective rope several times to form a height difference.
[0020] Injection curing type: Liquid silicone or other materials are injected through a transparent outer tube and locally cured, causing the center to bulge and form a limiting part.
[0021] In another embodiment, the raised structure 6 can be formed by dripping liquid curable material (such as instant adhesive, AB glue, hot melt adhesive, UV curing adhesive, etc.) onto the outer surface of the cable and allowing it to cure. The raised structure 6 is slightly higher than the surface of the main cable 2 body and is used to limit the downward path of the locking bead.
[0022] The raised structure 6 is located below the locking bead, which can prevent the locking bead from moving further when it slides down, preventing it from slipping off to the end of the main line protection rope, thus ensuring the integrity and stability of the fishing rig structure.
