Description

Technical Field

[0001] This utility model relates to the field of fishing rod technology, specifically a high-sensitivity fishing rod. Background Technology

[0002] As a common fishing tackle tool, the performance of a fishing rod directly affects its sensitivity and hook-up efficiency during fishing. Especially when fishing for fish with light bites or in complex waters, the "sensitivity" of the fishing rod—that is, its ability to transmit the subtle signals generated when a fish bites—becomes a key indicator affecting the actual use effect. Traditional high-sensitivity fishing rods often use high-modulus carbon fiber materials and lightweight designs to improve signal response speed, but they often suffer from problems such as discontinuous sensitivity transmission, easy structural fatigue, and inter-section vibration interference.

[0003] Firstly, in terms of structural design, existing fishing rods generally use a uniform or similar taper setting, ignoring the differences in force and response between different sections of the rod. This results in the rod tip having elasticity, but the signal is "attenuated" or "disconnected" when transmitted to the middle section or handle section, making it difficult to achieve continuous and highly sensitive transmission from the rod tip to the handle. Secondly, at the joints of the rod sections, since the connection between sections is mostly a rigid plug, high-frequency vibration interference is easily generated during instantaneous force processes such as casting and reeling, which in turn affects the angler's judgment of weak fish bites.

[0004] Therefore, it is necessary to provide a high-sensitivity fishing rod to solve the problems of signal attenuation, discontinuity and poor sensitivity stability in the existing technology, so as to improve the response efficiency and operation feel of the fishing process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a high-sensitivity fishing rod.

[0006] A high-sensitivity fishing rod is composed of five sections connected in sequence. The rod body includes a rod tip, a first rod section, a second rod section, a third rod section, and a handle rod section connected in sequence. The diameter of the rod body gradually decreases from the handle rod section towards the rod tip. The rod body is made of a multi-layer structure with adhesive layers between the layers. The first rod section and the second rod section have the same taper, and the third rod section and the handle rod section have the same taper. The taper ratio of the rod tip, the first rod section, and the handle rod section is 4:6.2:8. An elastic buffer ring is provided on the outer side of the rod tip, the first rod section, the second rod section, and the third rod section near the handle rod section. The outer side of the elastic buffer ring gradually increases in size from the two ends towards the middle.

[0007] Preferably, the multi-layer structure includes a first carbon fiber layer, a first composite braided layer, a second carbon fiber layer, a second composite braided layer, and a third carbon fiber layer. The first carbon fiber layer and the third carbon fiber layer are both woven from multiple carbon fiber bundles parallel to the axis of the rod length direction. The second carbon fiber layer is woven from multiple carbon fiber bundles perpendicular to the axis of the rod length direction. The first composite braided layer is woven from multiple composite fiber bundles woven at ±45° to the axis of the rod length direction. The second composite braided layer is woven from multiple composite fiber bundles woven at ±30° to the axis of the rod length direction.

[0008] Furthermore, the composite fiber bundle comprises multiple carbon fiber filaments and multiple glass fiber filaments, the ratio of carbon fiber filaments to glass fiber filaments in the first composite braided layer is 5:1, and the ratio of carbon fiber filaments to glass fiber filaments in the composite fiber bundle of the second composite braided layer is 4:1.

[0009] Preferably, the carbon fiber filament is a high-modulus carbon fiber filament.

[0010] Preferably, an aramid core rod is filled within the multi-layered structure of the rod tip.

[0011] Preferably, the elastic buffer ring is a silicone elastic buffer ring or a polymer elastic buffer ring, and the inner wall of the elastic buffer ring is tightly connected to the rod body.

[0012] Preferably, the surface of the handle rod body away from the rod tip is covered with a grip structure layer made of cork or EVA foam.

[0013] Preferably, the multi-layered structure is integrally cured and molded by hot pressing.

[0014] Preferably, the inner wall of the rod body is provided with a nano-reinforced coating, which comprises nano-silica particles and an epoxy resin matrix.

[0015] Preferably, the taper of the rod tip is 0.18% to 0.45%.

[0016] Preferably, the adhesive layer is an epoxy resin modified nano-adhesive layer. Specifically, the epoxy resin modified nano-adhesive layer is an epoxy resin adhesive layer with added nano-silica particles.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention provides a high-sensitivity fishing rod. First, the varying tapers between the rod sections create a gradual transition in stiffness and flexibility from the tip to the handle. The tip, with its smaller taper, offers better flexibility and instantaneous sensing, making it suitable for capturing subtle fish bites. The first and second rod sections have moderate tapers, serving as signal buffers and providing a gradual transition. The third and handle sections have larger tapers, resulting in high rigidity and better structural load-bearing and transmission stability, thus ensuring a more continuous and smooth signal transmission from the tip to the handle. This differentiated design effectively solves the sensitivity "discontinuity" and signal attenuation problems present in existing technologies, enhancing the continuity of sensitivity throughout the entire rod. Second, an adhesive layer is incorporated between the multi-layered structure. This adhesive layer fully fills the micro-gaps between the carbon fiber layers, improving the interfacial bonding strength, reducing interlayer stress concentration, and inhibiting the generation and propagation of micro-cracks. This, in turn, improves the overall structural stability of the fishing rod and its sensitivity retention over long-term use. Furthermore, elastic buffer rings are provided on the outer side of each rod section near the handle. These rings absorb the impact and high-frequency vibrations generated at the joints between rod sections during casting and lifting, effectively suppressing signal noise caused by mechanical interference and improving the rod's sensitivity and comfort during actual operation. Therefore, the high-sensitivity fishing rod of this application solves the problems of discontinuous signal transmission, structural fatigue, and vibration interference in traditional fishing rods, significantly improving the high-sensitivity performance of the rod.

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 1-4 This embodiment provides a high-sensitivity fishing rod, which is composed of five rod sections connected in sequence. The rod section includes a rod tip 10, a first rod body 20, a second rod body 30, a third rod body 40, and a handle rod body 50, all connected in sequence. The diameter of the rod body gradually decreases from the handle rod body 50 towards the rod tip 10. The rod body is made of a multi-layer structure with adhesive layers between the layers. The first rod body 20 and the second rod body 30 have the same taper. The third rod body 40 and the handle rod body... The tapers of the rod body 50 are the same. The taper ratio of the rod tip 10, the first rod body 20, and the handle rod body 50 is 4:6.2:8. An elastic buffer ring 60 is provided around the outer side of the end of the rod tip 10, the first rod body 20, the second rod body 30, and the third rod body 40 near the handle rod body 50. The outer diameter of the elastic buffer ring 60 gradually increases from the two ends to the middle, that is, the diameter is small at both ends and large in the middle.

[0027] It should be noted that the formula for calculating taper is taper = (D - d) / L, where D is the diameter of the large end of the rod, d is the diameter of the small end of the rod, and L is the length of the rod. When calculating, the units can be converted to mm.

[0028] It should also be noted that the 4:6.2:8 taper not only gives the fishing rod beneficial mechanical properties, but also greatly improves the continuity and sensitivity of signal transmission, thereby enhancing the fishing experience.

[0029] See Figure 2 Preferably, the multilayer structure includes a first carbon fiber layer 11, a first composite braided layer 12, a second carbon fiber layer 13, a second composite braided layer 14, and a third carbon fiber layer 15. The first carbon fiber layer 11 and the third carbon fiber layer 15 are both woven from multiple carbon fiber bundles parallel to the axis of the rod length direction. The second carbon fiber layer 13 is woven from multiple carbon fiber bundles perpendicular to the axis of the rod length direction. The first composite braided layer 12 is woven from multiple composite fiber bundles interlaced at ±45° to the axis of the rod length direction. The second composite braided layer 14 is woven from multiple composite fiber bundles interlaced at ±30° to the axis of the rod length direction.

[0030] It should be noted that this multi-layered structure optimizes the mechanical properties of the rod in all directions. First, the first carbon fiber layer 11 and the third carbon fiber layer 15, located parallel to the rod's length axis, are woven from multiple carbon fiber bundles, significantly improving the rod's longitudinal strength and stiffness. This gives the fishing rod higher bending resistance and more sensitive signal transmission performance, ensuring continuous sensitivity transmission from the rod tip 10 to the handle 50. Second, the second carbon fiber layer 13, positioned perpendicular to the rod's length axis, effectively enhances the rod's lateral strength and torsional resistance, preventing deformation and fatigue damage during use and improving the overall structural stability. Third, the first composite braided layer 12 uses composite fiber bundles interwoven at ±45° angles to the rod's axis. This interwoven structure improves the rod's shear strength and toughness, effectively absorbing and dispersing external impact forces, reducing the generation and propagation of micro-cracks. Simultaneously, the second composite braided layer 14, woven with composite fiber bundles at ±30° angles, further strengthens the rod's torsional resistance and local stress distribution, enhancing the overall durability of the rod. Therefore, this multi-layered structure enhances the mechanical strength and durability of the fishing rod while maintaining excellent signal transmission efficiency and flexible feedback capability, thus effectively ensuring the sensitivity and feel required during fishing.

[0031] Furthermore, the composite fiber bundle comprises multiple carbon fiber filaments and multiple glass fiber filaments. The ratio of carbon fiber filaments to glass fiber filaments in the first composite braided layer 12 is 5:1, while the ratio in the second composite braided layer 14 is 4:1. This composite fiber bundle achieves an optimized balance of performance by rationally mixing and weaving high-strength, high-modulus carbon fiber filaments with tough glass fiber filaments. Specifically, the first composite braided layer 12 has a 5:1 ratio of carbon fiber filaments to glass fiber filaments, resulting in a high carbon fiber content and excellent rigidity and responsiveness, which helps improve the overall elasticity and sensitivity of the fishing rod. The second composite braided layer 14 moderately increases the proportion of glass fiber, improving the interlayer toughness and impact resistance, helping to absorb external impacts, prevent crack propagation, and enhance the durability of the fishing rod. The combination of the two composite braided layers ensures both the high strength and high rigidity of the fishing rod and enhances its toughness and stability, thereby significantly improving the overall performance of the fishing rod and its sensitivity during fishing.

[0032] Preferably, the adhesive layer is an epoxy resin modified nano-adhesive layer. Specifically, the epoxy resin modified nano-adhesive layer is an epoxy resin adhesive layer with added nano-silica particles. That is, epoxy resin modified nano-adhesive layers are provided between the first carbon fiber layer 11 and the first composite braided layer 12, between the first composite braided layer 12 and the second carbon fiber layer 13, between the second carbon fiber layer 13 and the second composite braided layer 14, and between the second composite braided layer 14 and the third carbon fiber layer 15. These layers can be applied by coating during production. It should be noted that the epoxy resin modified nano-adhesive layer achieves tight interlayer bonding by uniformly dispersing nano-silica particles in traditional epoxy resin. Nano-silica particles have extremely high specific surface area and excellent dispersibility. Combined with epoxy resin, they can effectively fill the tiny gaps between multilayer structures, enhance interlayer interfacial adhesion, and reduce the generation and propagation of microcracks caused by stress concentration. Meanwhile, the nano-silica particles enhance the heat resistance and fatigue resistance of the adhesive layer, ensuring the structural stability and sensitivity of the fishing rod under long-term use and complex environments.

[0033] It should also be noted that the carbon fiber filaments and glass fiber filaments in the composite fiber bundle are formed by mechanically mixing and twisting them into bundles or by impregnation with adhesives or resins.

[0034] Preferably, the carbon fiber filament is a high-modulus carbon fiber filament, which has a high tensile modulus and rigidity, and can significantly improve the strength and bending resistance of the fishing rod.

[0035] Preferably, the multi-layered structure of the rod tip 10 is filled with an aramid core rod. The aramid core rod possesses an excellent strength-to-weight ratio, good fatigue resistance, and low density, effectively enhancing the structural strength and toughness of the rod tip 10 while maintaining a relatively light overall weight. Furthermore, the aramid core rod exhibits good vibration damping properties, helping to absorb and mitigate vibrations and impacts generated during fishing, thus improving the rod's sensitivity and user comfort.

[0036] Preferably, the elastic buffer ring 60 is a silicone elastic buffer ring 60 or a polymer elastic buffer ring 60, and the inner wall of the elastic buffer ring 60 is tightly connected to the rod body. Silicone and polymer materials have good elasticity and wear resistance, effectively absorbing the impact and vibration generated during casting and lifting, reducing the interference of mechanical vibration at the joints on signal transmission, thereby improving the overall sensitivity stability and user comfort of the fishing rod. It should be noted that the outer diameter of the elastic buffer ring 60 gradually increases from the ends towards the center, facilitating smooth extension and retraction of the fishing rod.

[0037] Preferably, the surface of the handle rod body 50 at the end away from the rod tip 10 is covered with a grip structure layer 16 made of cork or EVA foam. Cork has good anti-slip and breathability, providing a comfortable grip and reducing hand fatigue; while EVA foam is lightweight, has good cushioning and wear resistance, effectively improving grip comfort and shock absorption. By covering the handle structure layer 16, not only is the overall feel and operational flexibility of the fishing rod enhanced, but vibrations generated during operation are also effectively absorbed, further improving the user experience and sensitivity stability during fishing.

[0038] Preferably, the multi-layered structure is integrally cured and molded by hot pressing.

[0039] Preferably, the inner wall of the rod body is provided with a nano-reinforced coating, which comprises nano-silica particles and an epoxy resin matrix. This nano-reinforced coating can significantly improve the mechanical strength and wear resistance of the inner wall of the rod, effectively enhancing the overall rigidity and durability of the structure.

[0040] Preferably, the taper of the rod tip 10 is 0.18%~0.45%. This taper design gives the rod tip 10 good flexibility and elasticity, effectively improving the ability to detect weak fish bites and enhancing the sensitivity and response speed of the rod tip 10. More preferably, the taper of the rod tip 10 is 0.2%.

[0041] This invention provides a high-sensitivity fishing rod. First, the different tapers between the rod sections create a gradual transition in stiffness and flexibility from the tip 10 to the handle 50. The tip 10, with its smaller taper, offers better flexibility and instantaneous sensing capability, making it suitable for capturing subtle fish bites. The first and second rod sections 20 and 30 have moderate tapers, serving as signal buffers and gradual transitions. The third and fifth rod sections 40 and the handle 50 have larger tapers, resulting in high rigidity and better structural load-bearing and transmission stability. This ensures a more continuous and smooth signal transmission from the tip 10 to the handle. This differentiated design effectively solves the sensitivity "discontinuity" and signal attenuation problems existing in the prior art, enhancing the sensitivity continuity throughout the entire rod. Second, an adhesive layer is provided between the multi-layered structure. This adhesive layer fully fills the micro-gaps between the carbon fiber layers, improving the interfacial bonding strength, reducing interlayer stress concentration, and inhibiting the generation and propagation of micro-cracks. This improves the overall structural stability of the fishing rod and its sensitivity retention performance during long-term use. Furthermore, elastic buffer rings 60 are provided on the outer side of each rod section near the handle. These elastic buffer rings 60 can absorb the impact force and high-frequency vibration generated at the joints between sections during casting and lifting, effectively suppressing signal noise caused by mechanical interference and improving the sensitivity and comfort of the fishing rod in actual operation. Therefore, the high-sensitivity fishing rod of this application solves the problems of discontinuous signal transmission, structural fatigue, and vibration interference in traditional fishing rods, and significantly improves the high-sensitivity performance of the fishing rod.

[0042] 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.
