Description

Technical Field

[0001] This utility model relates to the field of fishing reel technology, specifically a corrosion-resistant double-helix guide rod fishing reel. Background Technology

[0002] As a crucial device for controlling the retrieval and release of fishing line during fishing, the performance of the fishing reel directly affects the efficiency and experience of fishing. To achieve even line winding and smooth line release, some mid-to-high-end fishing reels employ a double-helix guide rod structure. This structure, through the inclusion of guide grooves with left-hand and right-hand threads, allows the guide ring assembly to reciprocate along the guide rod's axis, thereby evenly winding the fishing line onto the spool and effectively preventing problems such as tangling and knotting, thus improving the reel's performance.

[0003] In existing technologies, double-helix guide rods are typically made of metal materials such as stainless steel and aluminum alloys. While metal materials possess certain mechanical strength and wear resistance, during long-term use, especially in natural aquatic environments (such as freshwater and seawater) where fishing line is repeatedly cast and retrieved, the fishing line carries moisture and corrosive impurities into the guide rod surface, leading to problems such as rust, oxidation, and surface wear. This not only affects the smoothness of the guide swivel's movement, causing uneven line winding and jamming, but can even cause the fishing reel to malfunction, severely impacting the fishing experience and equipment lifespan. Therefore, it is necessary to provide a double-helix guide rod fishing reel that can improve the smoothness of the guide swivel's operation and extend its service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a corrosion-resistant double-helix guide rod fishing reel, which effectively improves the problem of insufficient smooth operation of the guide rings in some traditional fishing reels after long-term use, leading to uneven line winding, jamming, and even reel failure.

Detailed Implementation

[0025] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] See Figures 1-6 This embodiment provides a corrosion-resistant double helix guide rod 50 fishing reel, which includes a fishing reel body 10, a rocker arm 20 disposed at one end of the fishing reel body 10, a rotating shaft 30 connected to the rocker arm 20, a main shaft 40 pulverically connected to the rotating shaft 30, and a double helix guide rod 50. A line cup 60 is disposed on the outer side of the main shaft 40. The upper surface of the double helix guide rod 50 is provided with left-hand and right-hand threaded guide grooves 51. A guide ring assembly 70 is reciprocally slidably connected to the guide grooves 51. The wire ring assembly 70 described in this application includes a wire seat 71. A guide eye 72 is provided at one end of the wire seat 71. A guide claw 73 is embedded on the side of the wire seat 71 that contacts the PEEK double helix guide rod 50. The guide claw 73 extends into the guide groove 51 on the side near the PEEK double helix guide rod 50. A wire seat nut 74 that cooperates with the guide claw 73 is provided on the side of the wire seat 71 away from the PEEK double helix guide rod 50.

[0027] In this embodiment, the PEEK double helix guide rod 50 serves as the running track for the guide ring assembly 70. Its main function is to guide the guide ring assembly 70 to reciprocate along the guide rod axis, achieving uniform winding of the fishing line. The outer surface of the PEEK double helix guide rod 50 is provided with left-hand and right-hand threaded guide grooves 51, and the guide claws 73 in the guide ring assembly 70 can be embedded in the guide grooves 51. When the user rotates the rocker arm 20 to drive the rotating shaft 30 to rotate, and then drives the main shaft 40 to rotate through the gear, the rotation of the main shaft 40 drives the spool 60 to take in the line, while the rotating shaft 30 also drives the double helix guide rod 50 to rotate. Due to the helical structure of the guide grooves 51, the guide ring assembly 70 will make reciprocating linear motion along the axial direction of the double helix guide rod 50 under the constraint of the guide claws 73, thereby changing the process of taking in the line into uniformly winding the fishing line onto the spool 60.

[0028] Specifically, the double-helix guide rod 50 described in this application is a PEEK double-helix guide rod 50. The PEEK double-helix guide rod 50 includes a PEEK double-helix guide rod body 52 and, from the inside out, a UV-resistant layer 53, a waterproof layer 54, and a wear-resistant layer 55 sequentially disposed on the outer side of the PEEK double-helix guide rod body 52. ​​The PEEK double-helix guide rod body 52 is made of PEEK (polyetheretherketone) material, which gives it excellent corrosion resistance, high-temperature resistance, and dimensional stability. It can be used for a long time in humid, hot, salty, and corrosive environments, making it particularly suitable for complex aquatic environments such as sea fishing. The UV-resistant layer 53 on its outer surface can effectively block ultraviolet radiation and prevent the PEEK material from aging, becoming brittle and other performance degradation problems caused by long-term sun exposure; the waterproof layer 54 further enhances the barrier ability of the guide rod surface against water vapor, prevents water from corroding the guide rod structure for a long time, and improves the overall sealing performance; the wear-resistant layer 55 effectively reduces the mechanical wear on the guide rod surface caused by the reciprocating sliding of the guide ring assembly 70, and extends the overall service life of the guide rod.

[0029] Preferably, the guide ring assembly 70 further includes a sheath 80 and a guide rod 90. The sheath 80 is sleeved on the outside of the PEEK double helix guide rod 50, and the guide rod is parallel to the sheath 80 and disposed on the side of the sheath 80. The guide seat 71 has two through holes 75 adapted to the sheath 80 and the guide rod 90, and the two through holes 75 are respectively movably sleeved on the outside of the sheath 80 and the guide rod 90. It should be noted that the through holes 75 are respectively movably sleeved on the outside of the sheath 80 and the guide rod 90 in order to realize the smooth reciprocating movement of the guide seat 71 on the PEEK double helix guide rod 50. Specifically, the sheath 80 and the guide rod 90 form a pair of parallel sliding guide structures. When the guide seat 71 slides with the sheath 80 and the guide rod through its two through holes 75, it can synchronously achieve stable axial reciprocating movement under the guidance of the guide groove 51 of the double helix guide rod 50.

[0030] Furthermore, the two through holes 75 are respectively located at one end of the wire seat 71 away from the guide eye 72 and at the middle of the wire seat 71.

[0031] Preferably, the guide eye 72 has a ring, square, or conical structure, which allows it to adapt to the passage requirements of different types and thicknesses of fishing lines.

[0032] Preferably, the UV-resistant layer 53 is a titanium dioxide nano-UV-resistant layer 53 or a polyvinylidene fluoride (PVDF) UV-resistant layer 53. The titanium dioxide nano-UV-resistant layer 53 possesses excellent UV shielding performance and stable photocatalytic inertness, effectively preventing the PEEK double-helix guide rod body 52 from aging and becoming brittle due to long-term exposure to sunlight. The PVDF UV-resistant layer 53 combines good weather resistance and UV resistance with certain corrosion resistance and mechanical flexibility, helping to enhance the environmental adaptability of the PEEK double-helix guide rod body 52. ​​Therefore, by incorporating this UV-resistant layer 53, the durability and stability of the PEEK double-helix guide rod body 52 in outdoor fishing scenarios can be significantly improved.

[0033] Preferably, the waterproof layer 54 is a fluorosilicone rubber waterproof layer 54, a polytetrafluoroethylene waterproof layer 54, or a nano-silica waterproof layer 54. The fluorosilicone rubber waterproof layer 54 has excellent waterproof performance and resistance to high and low temperatures, effectively preventing moisture penetration and keeping the internal structure of the guide rod dry. The polytetrafluoroethylene waterproof layer 54 has extremely low water absorption and good chemical inertness, enabling long-term stable operation in acidic, alkaline, or salt spray environments. The nano-silica waterproof layer 54, relying on its superhydrophobic nanostructure, constructs a lotus leaf effect surface, effectively preventing water droplet adhesion and improving the overall protection level. By setting this waterproof layer 54, the stability and reliability of the PEEK double-helix guide rod 50 in humid or water-filled environments can be significantly enhanced, extending its service life.

[0034] Preferably, the wear-resistant layer 55 is a tungsten carbide wear-resistant layer 55, a titanium nitride ceramic wear-resistant layer 55, or a polyimide wear-resistant layer 55. The tungsten carbide wear-resistant layer 55 possesses extremely high hardness and excellent impact resistance, effectively resisting wear on the surface of the PEEK double-helix guide rod 50 caused by the high-frequency reciprocating motion of the guide ring assembly 70. The titanium nitride ceramic wear-resistant layer 55 combines high hardness, low coefficient of friction, and good oxidation resistance, reducing frictional resistance while ensuring wear resistance. The polyimide wear-resistant layer 55, with its excellent high-temperature resistance and chemical corrosion resistance, offers advantages in lightweight and flexibility, making it suitable for dynamic contact conditions in complex environments. By incorporating this wear-resistant layer 55, the wear resistance and fatigue resistance of the outer surface of the PEEK double-helix guide rod 50 can be significantly improved, thereby ensuring the sliding stability of the guide ring assembly 70 during long-term use and the service life of the overall fishing reel structure.

[0035] Preferably, an alkali-resistant layer 56 is provided between the UV-resistant layer 53 and the waterproof layer 54. The alkali-resistant layer 56 is a silane coupling agent alkali-resistant layer 56 or an organosilicon alkali-resistant layer 56. This alkali-resistant layer 56 can effectively block alkaline substances from corroding the PEEK double-helix guide rod body 52, enhance the adhesion between layers and the stability of the overall structure, thereby further improving the corrosion resistance and service life of the guide rod.

[0036] Preferably, the rotating shaft 30 is connected to the main shaft 40 and the double helix guide rod 50 by gear meshing, so as to realize stable power transmission and coordinated movement, enabling the main shaft 40 and the double helix guide rod 50 to rotate synchronously, thereby ensuring the smooth sliding of the guide ring assembly 70 and the uniform winding of the fishing line, and improving the overall performance and reliability of the fishing reel.

[0037] This utility model provides a corrosion-resistant double-helix guide rod 50 fishing reel, which uses a PEEK double-helix guide rod 50, significantly improving the reel's adaptability in complex natural aquatic environments such as humid, saline, and impurity-rich waters. The PEEK double-helix guide rod 50 has excellent corrosion resistance and mechanical strength, effectively resisting the erosion of the guide rod by water, salt, and other corrosive substances, preventing reel malfunctions caused by guide rod corrosion or breakage. Simultaneously, an anti-UV layer 53, a waterproof layer 54, and a wear-resistant layer 55 are provided on the outer side of the PEEK double-helix guide rod 50. This not only further enhances the PEEK double-helix guide rod 50's resistance to ultraviolet radiation, preventing material aging and brittleness, but also effectively isolates water penetration through the waterproof layer 54. Furthermore, the outermost wear-resistant layer 55 enhances the wear resistance of the PEEK double-helix guide rod 50 surface during repeated sliding of the guide ring, making the reciprocating motion lighter, delaying wear, and improving the overall operational stability and service life of the fishing reel. The corrosion-resistant double helix guide rod of the 50 fishing reel significantly improves the corrosion problems of existing fishing reels using metal guide rods, enhancing product reliability and user experience.

[0038] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
