Description

Technical Field

[0001] This utility model relates to the field of fishing tools, and in detail, it is a fishing line rotating connection device that prevents the lower end of the connecting shaft from contacting the connecting sleeve during use, thus avoiding friction noise and damage, and ensuring that the connecting rope is firmly fixed and has a long service life. Background Technology

[0002] We know that during fishing, to facilitate the handling of a fish, the tip of the fishing rod is usually connected to the fishing line using a fishing line swivel connector. The existing structure of a fishing line swivel connector for connecting the fishing rod and line is as follows: It has a connecting sleeve, with a freely rotatable connecting shaft inside the front part of the connecting sleeve. The connecting shaft inside the connecting sleeve has an annular rotating connecting groove. Opposite to the rotating connecting groove on the connecting sleeve is a connecting protrusion that fits into it. The connecting protrusion is usually formed by pressing the connecting sleeve into the rotating connecting groove using a pressing tool, and is used to axially fix the connecting shaft inside the connecting sleeve. A connecting rope for connecting the fishing line is attached to the connecting shaft on the front side of the connecting sleeve. The connecting rope is usually tied to the front end of the connecting shaft or glued on. The existing fishing line rotating connection device requires an anti-detachment head at the front end of the connecting shaft when the connecting rope is tied to it, which is unsightly. When the connecting rope is glued to the front end of the connecting shaft, the connection is not secure and the rope is prone to falling off after prolonged use. The connecting shaft and the connecting sleeve have a clearance fit, and during use, the lower end of the connecting shaft is prone to contact with the line in the connecting sleeve. When the connecting shaft rotates relative to the connecting sleeve, it is easy to generate friction noise, and prolonged use can easily damage the connecting sleeve. Especially after a period of use (multiple vigorous fish-playing sessions), the gap between the connecting shaft and the connecting sleeve widens, and the friction noise and damage will increase. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fishing line rotating connection device in which the lower end of the connecting shaft does not contact the connecting sleeve, thus avoiding friction noise and damage, and the connecting rope is firmly fixed and has a long service life.

[0004] The technical solution adopted by this utility model to overcome the shortcomings of the prior art is:

[0005] A fishing line rotating connection device includes a connecting shaft, a connecting sleeve, and a connecting rope. The connecting shaft has a limiting boss in the middle. The lower part of the connecting shaft is rotatably installed in the connecting sleeve. The connecting shaft inside the connecting sleeve has an annular rotating connecting groove. The inner side of the connecting sleeve, opposite to the rotating connecting groove, has a connecting protrusion embedded therein and cooperating with it. The device is characterized in that the lower end of the connecting shaft has a connecting post, and the connecting post has a limiting retaining ring. The outer diameter of the limiting retaining ring is 0.95-1.05 times the outer diameter of the connecting shaft. The inner side of the connecting sleeve below the limiting retaining ring has a limiting protrusion.

[0006] Preferably, the limiting retaining ring is made of polytetrafluoroethylene (PTFE). PTFE has an extremely low coefficient of friction, which limits and prevents the lower end of the connecting shaft from contacting the connecting sleeve while reducing the resistance to the rotation of the connecting shaft.

[0007] Preferably, the limiting ring is made of silicone or rubber material; it has a certain degree of elasticity, is low in cost, and is easy to assemble.

[0008] Preferably, the connecting column is equipped with two limiting rings. The two limiting rings are rubber rings with a certain degree of elasticity, which are simple and convenient to install and have a better anti-friction effect.

[0009] In a further improvement of this utility model, the upper part of the connecting shaft above the limiting protrusion is provided with an anti-detachment groove, one end of the connecting rope is sleeved on the upper part of the connecting shaft, and at least one layer of metal wire is wound around the outside of the connecting rope sleeved on the upper part of the connecting shaft, and the metal wire is brushed with adhesive.

[0010] Preferably, the adhesive is epoxy resin; the epoxy resin can penetrate into the connecting rope inside the metal wire, resulting in a strong bond and high tensile strength.

[0011] Preferably, the upper part of the connecting shaft above the limiting protrusion is provided with at least three anti-detachment grooves, which are annular grooves with gradually increasing depth from bottom to top. This makes the connection more secure.

[0012] Preferably, the upper end of the connecting shaft is tapered with a gradually decreasing diameter. This facilitates insertion into the end of the connecting rope and improves production efficiency.

[0013] The rotating connecting groove described in this invention has a rectangular cross-section. The rectangular cross-section of the rotating connecting groove greatly increases the axial contact length and contact area between it and the connecting protrusion, resulting in more uniform force distribution, less deformation of the connecting protrusion, and more stable fit.

[0014] In use, the connecting rope is connected to the fishing line, and the lower part of the connecting sleeve is bonded to the tip of the fishing rod with adhesive. When the fishing line is pulled and the connecting rope swings left and right, the connecting rope drives the connecting shaft to rotate inside the connecting sleeve. At this time, due to the clearance fit between the connecting shaft and the connecting sleeve, the connecting shaft is prone to tilting. However, when the connecting shaft tilts, the limiting ring at the lower end of the connecting shaft contacts the inner wall of the connecting sleeve, preventing direct line contact and friction between the lower outer edge of the metal connecting shaft and the metal connecting sleeve. Because the limiting ring is made of polytetrafluoroethylene, silicone, rubber, or other materials, it does not generate significant frictional noise and will not damage the inner wall of the connecting sleeve. The anti-detachment groove on the connecting shaft, the metal wire wrapped around the outside of the connecting rope, and the applied adhesive make the connection between the connecting rope and the connecting shaft more secure, with high tensile strength, less prone to damage, and longer service life.

[0018] like Figure 1 , Figure 2 , Figure 3 The fishing line rotating connection device shown includes a connecting shaft 5, a connecting sleeve 9, and a connecting rope 1. The connecting shaft 5 has a limiting boss 3 in the middle. The lower part of the connecting shaft 5 is rotatably installed in the connecting sleeve 9. The upper end face of the connecting sleeve 9 is located below the limiting boss 3. The connecting shaft 5 inside the connecting sleeve 9 has an annular rotating connecting groove 13. On the inner side of the connecting sleeve 9, opposite to the rotating connecting groove 13, there is a connecting protrusion 4 embedded therein and cooperating with it. The rotating connecting groove 13 has a rectangular cross-section. The rectangular cross-section of the rotating connecting groove 13 greatly increases the axial contact length and contact area between it and the connecting protrusion 4, resulting in more uniform force distribution, less deformation of the connecting protrusion, and more stable fit. A connecting post 7 is provided at the lower end of the connecting shaft 5, and a limiting ring 6 is provided on the connecting post 7. The limiting ring 6 can be made of polytetrafluoroethylene (PTFE), silicone, or rubber. PTFE has an extremely low coefficient of friction, and the limiting ring 6 serves to limit and prevent the lower end of the connecting shaft from contacting the connecting sleeve, while also reducing the resistance to the rotation of the connecting shaft. Silicone or rubber materials have a certain degree of elasticity, and the limiting rings made from them are low in cost and easy to assemble. The outer diameter of the limiting ring 6 is 1 times the outer diameter of the lower part of the connecting shaft 5, and it fits the connecting sleeve with a clearance, resulting in low friction during contact. A limiting protrusion 8 is provided on the inner side of the connecting sleeve 9 below the limiting ring 6, which prevents the limiting ring from moving up and down on the connecting post.

[0019] Further improvements include the addition of two limiting rings on the connecting column. These two limiting rings are made of elastic rubber, making installation simple and convenient, and providing better anti-friction performance.

[0020] Further improvements include five anti-detachment grooves 12 on the upper part of the connecting shaft 5 on the upper side of the limiting boss 3. These anti-detachment grooves 12 are annular grooves with gradually increasing depth from bottom to top. One end of the connecting rope 1 is sleeved on the upper part of the connecting shaft 5. Two layers of metal wire 11 are wound around the outside of the connecting rope 1 sleeved on the upper part of the connecting shaft 5, and the metal wire 11 is coated with adhesive 10. The adhesive 10 is epoxy resin. The epoxy resin can penetrate into the connecting rope inside the metal wire, resulting in a strong bond and high tensile strength. Furthermore, the upper end 2 of the connecting shaft 5 is tapered with a gradually decreasing diameter, facilitating insertion into the end of the connecting rope and improving production efficiency.

[0021] In use, the connecting rope is connected to the fishing line, and the lower part of the connecting sleeve is bonded to the tip of the fishing rod with adhesive. When the fishing line is pulled and the connecting rope swings left and right, the connecting rope drives the connecting shaft to rotate inside the connecting sleeve. At this time, due to the clearance fit between the connecting shaft and the connecting sleeve, the connecting shaft is prone to tilting. However, when the connecting shaft tilts, the limiting ring at the lower end of the connecting shaft contacts the inner wall of the connecting sleeve, preventing direct line contact and friction between the lower outer edge of the metal connecting shaft and the metal connecting sleeve. Because the limiting ring is made of polytetrafluoroethylene, silicone, rubber, or other materials, it does not generate significant frictional noise and will not damage the inner wall of the connecting sleeve. The anti-detachment groove on the connecting shaft, the metal wire wrapped around the outside of the connecting rope, and the applied adhesive make the connection between the connecting rope and the connecting shaft more secure, with high tensile strength, less prone to damage, and longer service life.
