Abstract
Description
Technical Field
[0001] This utility model relates to the field of float technology, specifically to a highly adaptable locking structure for through-hole floats. Background Technology
[0002] As is well known, most existing through-hole floats use a pre-embedded rubber bead locking structure. The rubber bead is permanently fixed in the float channel during production, and the fishing line is only rubbed against the small contact surface. The locking force is weak, and even slight vibrations can cause the float to shift. When fishing, the position needs to be adjusted repeatedly. The fishing line must be threaded into the channel using a special guide tool, which is time-consuming and prone to failure. It is difficult for beginners to complete the installation independently. Moreover, the rubber bead loses its elasticity after aging, and the float locking function completely fails. When adjusting the float position, the fishing line needs to be cut, which damages the integrity of the fishing rig and wastes resources. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a highly adaptable locking structure for through-hole floats.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly adaptable locking structure for a through-hole float, comprising a float body, an internal channel, and through holes between the channel and both ends of the float body. A fishing line is positioned on the channel, and a detachable elastic silicone line is positioned between the channel and the fishing line. The diameter of the elastic silicone line and the diameter of the fishing line are both larger than the through holes, allowing the fishing line to be wrapped around the line through elastic deformation.
[0007] Furthermore, an improvement of this invention is that the elastic silicone wire is a hollow cylinder.
[0008] Furthermore, the present invention is improved in that the hardness range of the elastic silicone wire is Shore A30-50.
[0009] Furthermore, an improvement of this invention is that the length of the elastic silicone wire covers more than 80% of the total length of the internal channel.
[0010] (III) Beneficial Effects
[0011] Compared with the prior art, this utility model provides a highly adaptable locking structure for through-hole floats, which has the following beneficial effects:
[0012] This Zhongtong float features a highly adaptable locking structure. After the silicone line is wrapped and fixed to the fishing line, it is directly inserted into the channel. The silicone core deforms and is compressed by the channel, completing the installation and eliminating the need for tools. The silicone line is compressed within the limited space of the channel, forming a comprehensive wrap around the fishing line and ensuring locking force. Even in a continuously shaking environment, the float body remains stable. The float body can be slid by forcefully pulling the fishing line by hand. Wear gloves during operation to prevent cuts and preserve the fishing rig intact. When changing the line, hold the float body and pull the fishing line forcefully. The old silicone line is pulled out with the fishing line, and the new line is wrapped and re-inserted, achieving minute-level quick maintenance. The silicone line is independently injection molded, resulting in extremely low cost, and a single specification is compatible with all types of fishing lines, simplifying the production process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-4This utility model relates to a highly adaptable locking structure for a centrally located float, comprising a float body 1. The float body 1 has an internal channel 2, and through holes 3 are formed between the channel 2 and both ends of the float body 1. A fishing line 4 is mounted on the channel 2, and a detachable elastic silicone line 5 is positioned between the channel 2 and the fishing line 4. The diameter of the elastic silicone line 5 and the diameter of the fishing line 4 are larger than the through holes 3. The fishing line 4 is wrapped around the elastic silicone line 5 through elastic deformation. In this embodiment, the fishing line 4 is wrapped and secured by the elastic silicone line 5, such as by tying a rope. Then, the fishing line 4 passes through the channel 2 from one end of the float body 1 through the through hole 3 and exits from the other end through the through hole 3. The wrapped portion of the elastic silicone line 5 is then forcefully squeezed into the through hole 3, and the fishing line 4 is pulled, thereby causing the elastic silicone line 5 to... As the fishing line 4 moves to the channel 2, the elastic silicone line 5 is positioned. The space in the channel 2 is small, which allows for sufficient compression of the elastic silicone line 5. This ensures that the elastic silicone line 5 keeps the fishing line 4 firmly pressed and secured within the channel 2, thus achieving a secure assembly of the float body 1 onto the fishing line 4. During production and use, the float body 1 will not move on the fishing line 4 under vibrations such as shaking or small pulling forces. When personnel need to adjust the position of the float body 1, they can firmly grasp the float body 1, then wear gloves and pull the fishing line 4 to move the float body 1 on the fishing line 4. Wearing gloves prevents the fishing line 4 from scratching the hands. The elastic silicone line 5 has a long service life and can be used in float bodies 1 of different sizes and types, demonstrating excellent applicability.
[0020] To further improve the elastic fastening effect, in this design, the elastic silicone line 5 is a hollow cylinder. By making the elastic silicone line 5 a hollow cylinder, the elastic support effect is improved, and when it is wrapped around the fishing line 4 and placed inside the float body 1, it provides a more secure and reliable elastic support for the fixation between the float body 1 and the fishing line 4.
[0021] To improve aging resistance, in this design, the elastic silicone wire 5 has a hardness range of Shore A30-50, exhibiting excellent physical, chemical, and thermal stability, which enhances the overall aging resistance when used in this structure.
[0022] To ensure a tighter bond between the float body 1 and the fishing line 4, in this design, the length of the elastic silicone line 5 covers more than 80% of the total length of the internal channel 2. By ensuring the elastic silicone line 5 occupies more than 80% of the total length of the channel 2, a tighter damping and securing effect can be applied between the elastic silicone line 5 and the float body 1.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
