Description

Technical Field

[0001] The utility model relates to the technical field of fishing gear, in particular to a fishing line anti-bite protective cover. Background Art

[0002] In modern fishing, fishing line is a crucial tool connecting anglers and fish, and its performance directly impacts both efficiency and success. Traditional fishing lines are easily snapped by sharp-toothed fish, leading to failed attempts and causing inconvenience and financial losses for anglers. Furthermore, the joints of fishing lines are also prone to breakage, especially when subjected to high tension. Uneven force at the knot can easily cause line breakage, increasing fishing costs and negatively impacting the overall fishing experience.

[0003] To address these issues, various types of fishing lines have emerged on the market, including nylon, PE (polyethylene), and carbon lines. Nylon lines have good ductility and water-cutting properties, but their abrasion resistance and aging resistance are poor. PE (Dyneema) lines are known for their high strength and abrasion resistance, but they have a low specific gravity, are not easy to sink, and have poor heat resistance. Carbon lines are favored for their high specific gravity, fast water-cutting, and abrasion resistance, but their knotting strength is weak and they are not suitable for use as main lines.

[0004] While these fishing lines offer advantages in specific areas, they still face limitations in practical applications. For example, nylon lines are prone to aging and curling, PE lines have poor heat resistance, and carbon lines have weak knotting strength. Therefore, developing a new type of anti-snap protective cover for fishing lines that maintains the original performance of the fishing line while providing additional protection to prevent line snaps and improve fishing efficiency has become an important research direction in the field of fishing equipment. This cover needs to have a simple structure, be easy to install, and be durable to adapt to different fishing environments and needs. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A fishing line anti-bite protective sleeve includes a sleeve 1 that is sleeved onto the outer wall of the fishing line. The sleeve 1 is generally 5 cm to 20 cm long. The bottom of the sleeve 1 is provided with a connecting groove 2 for inserting a fish hook. The connecting groove 2 has a flat oval cross-section, and the diameter of the connecting groove 2 should not differ too much from the outer diameter of the fish hook tail, with an interference fit being optimal.

[0024] When the hook is inserted into the connecting groove 2, the buoyancy of the water will not cause the connecting groove 2 to separate from the hook. The tail of the hook is inserted into the connecting groove 2, so that the position of the hook and the connecting groove 2 is fixed, thereby preventing the sleeve 1 from sliding on the outer wall of the fishing line, so that the fish bites the sleeve 1 when biting the hook, avoiding the fishing line being bitten.

[0025] The connecting trough 2 is provided with expansion slots 6 on opposite sides of the inner wall. The inner side of the expansion slots 6 is used to place the fishing line to prevent the fishing line from being tied to the tail of the fish hook, which makes it difficult to insert the tail of the fish hook into the connecting trough 2. The expansion slots 6 extend smoothly to the inner side of the sleeve 1. During the process of fishing, the fish will roll and sway. The smooth inner wall of the expansion slots 6 is provided to prevent the fishing line from being worn and broken.

[0026] Both the casing 1 and the connecting trough 2 are made of a rigid, transparent PC tube, and are integrally formed. Fish, especially marine fish, have sharp teeth, and the soft casing 1 can be bitten and scratched, potentially rubbing against the fishing line. Fishing line, however, is subject to significant pulling force, and any damage to its cross-section can easily cause it to break. Using a rigid material significantly mitigates this problem. Furthermore, using a transparent setting increases the variety of fish that can be caught, as many fish are easily attracted to other colors, while others are easily scared away. This is why transparent tubes are used.

[0027] The top of the sleeve 1 is provided with a knot plug 3. The top of the outer wall of the sleeve 1 is provided with an external thread 4. The inner wall of the knot plug 3 is provided with an internal thread 5. The external thread 4 and the internal thread 5 are threadedly connected, thereby connecting the knot plug 3 and the sleeve 1 together. The knot plug 3 can compress the knot of the fishing line tied to the fishhook to prevent the knot from loosening and gradually pulling apart when the fishhook is under pressure, causing it to become unhooked. The top of the knot plug 3 has a hole, through which the fishing line passes through the hole and the knot plug 3.

[0028] The opening edge of the knot sealing head 3 should be kept smooth to avoid cutting the line.

[0029] The inner side of the knot sealing head 3 is provided with a receiving cavity for placing the fishing line knot, and the knot for tying the fishing line to the fish hook is placed in the receiving cavity opened in the knot sealing head 3.

[0030] A gap is provided between the external thread 4 and the internal thread 5, the size of which is approximately the same as the diameter of the fishing line. After tying the fishing line with a knot, the excess thread is wrapped along the external thread and around the outer wall of the sleeve 1. The knot plug 3 is then twisted onto the end of the sleeve 1 to secure the fishing line. This further reduces the probability of the fishing line knot being pulled apart due to excessive force.
