Description

Technical Field

[0002] Currently, fishing rods are an indispensable tool in fishing activities, and their structural performance directly affects casting feel, fish control efficiency, and overall durability. Traditional fishing rods are mostly made of composite materials such as fiberglass or carbon fiber, and their strength and rigidity are improved through multi-layer winding or hot-pressing processes. However, in actual use, especially when dealing with large or high-strength fish, existing fishing rods often suffer from insufficient waist support, weak rod rebound, and excessive deformation, thus affecting the accuracy of fish control and their service life. Therefore, it is necessary to provide a fishing rod with a reasonable structure, balanced performance, and stronger waist support to meet the needs of high strength, high elasticity, and high stability in actual fishing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a strong waist force fishing rod, which effectively improves the defects of some traditional fishing rods such as poor strength and insufficient waist elasticity.

[0004] A high-strength fishing rod includes a rod body composed of multiple sections connected sequentially, with the diameter of the rod body gradually decreasing from the handle towards the tip. The rod body is formed by a multi-layer structure, comprising, from the inside out, a first carbon fiber layer, a composite braided layer, a second carbon fiber layer, and a glass fiber strip layer. The first carbon fiber layer and the second carbon fiber layer are both woven from multiple carbon fiber bundles parallel to the axis of the rod body's length. The composite braided layer consists of multiple glass fibers interwoven at ±45° to the axis of the rod body's length, and multiple carbon fiber bundles parallel to the axis of the rod body's length. The carbon fiber bundles of the composite braided layer are interwoven between the interwoven glass fibers. The glass fiber strip layer is woven from multiple glass fiber strips and is spirally wound around the outside of the second carbon fiber layer at an angle of 15-30°. A glass fiber reinforcement layer is disposed between the first carbon fiber layer and the composite braided layer in the middle of the rod body.

[0005] Preferably, the first carbon fiber layer and the second carbon fiber layer are prepreg-molded structures, consisting of multiple parallel carbon fiber bundles parallel to the axis of the rod length direction. The carbon fiber bundles are kept in a stable relative position by hot melt adhesive spot bonding or interlaced mesh positioning fibers.

[0006] Furthermore, the glass fiber reinforcement layer is made of high-density plain-weave glass fiber cloth and is fully covered along the axial direction of the fishing rod in the middle of the rod body.

[0007] Preferably, the ratio of interwoven glass fibers to carbon fiber bundles in the composite braided layer is 1:1 to 2:1.

[0008] Preferably, the glass fiber tape layer is composed of parallel bundles of neatly arranged glass fibers, and maintains its tape shape by resin pre-impregnation or bonding.

[0009] Preferably, the ratio of the thickness of the first carbon fiber layer to the thickness of the second carbon fiber layer is 1:1.5 to 1:2.

[0010] Preferably, both the inner and outer sides of the glass fiber tape layer are impregnated with epoxy resin layers.

[0011] Preferably, the rod body is assembled with a telescopic structure or by plug-in connection.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model provides a high-strength fishing rod, including a rod body composed of multiple sections connected sequentially, with the diameter of the rod body gradually decreasing from the handle to the tip. The rod body is formed by a multi-layer structure, comprising, from the inside out, a first carbon fiber layer, a composite braided layer, a second carbon fiber layer, and a glass fiber strip layer. The first and second carbon fiber layers are arranged parallel to the rod body axis, providing good longitudinal tensile strength and basic support. The composite braided layer is formed by multiple carbon fiber bundles interlaced at ±45° angles and parallel to the rod body's length axis, giving the rod excellent torsional resistance and multi-directional force coordination. The outermost glass fiber strip layer is spirally wound around the second carbon fiber layer, improving the rod's circumferential stability and crack and wear resistance. Furthermore, the glass fiber reinforcement layer added to the middle section of the rod body effectively strengthens the bending load-bearing and rebound control capabilities in the waist area, thereby enhancing the "waist strength" performance during fish handling. Therefore, this high-strength fishing rod has the advantages of good longitudinal strength, torsional rigidity and flexibility. It can keep the rod body stable and not easily deformed when facing large fish with high explosive power, and quickly return to its original shape, improving the accuracy of fish control and the efficiency of force application.

[0019] 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.

[0020] See Figures 1-3 This embodiment provides a strong waist force fishing rod, including a fishing rod body. The fishing rod body is composed of multiple rod body 10 sections connected in sequence, and the diameter of the fishing rod body gradually decreases from the handle to the tip. The rod body 10 is formed by winding a multi-layer structure. The multi-layer structure includes a first carbon fiber layer 20, a composite braided layer 30, a second carbon fiber layer 40, and a glass fiber tape layer 50 arranged sequentially from the inside to the outside.

[0021] Specifically, both the first carbon fiber layer 20 and the second carbon fiber layer 40 are woven from multiple carbon fiber bundles parallel to the axis of the rod body 10 along its length. Preferably, the first carbon fiber layer 20 and the second carbon fiber layer 40 are prepreg-molded structures. Specifically, the first carbon fiber layer 20 and the second carbon fiber layer 40 are each composed of several carbon fiber bundles, each containing multiple continuous monofilaments (such as 12K and 24K specifications), laid parallel to the axial direction (i.e., the 0° direction) of the rod body 10. To ensure the consistency and stability of fiber arrangement during the winding or molding process, the carbon fiber bundles in each layer are bonded together with hot melt adhesive in a dotted manner, or laterally positioned and woven with a fine mesh of low-gram redirected fiber filaments, thereby limiting the relative displacement and torsion between bundles and forming a consistent sheet with dimensional stability and good wetting performance.

[0022] Meanwhile, the first carbon fiber layer 20 is preferably laid on the inner side of the rod body 10, mainly providing primary longitudinal strength and supporting rigidity, and is relatively thin to ensure the flexibility of the rod body 10 at the base; while the second carbon fiber layer 40 is located on the outside of the structure, with a larger layer thickness and a higher density than the first carbon fiber layer 20, to enhance the overall tensile strength and bending rigidity of the rod body 10. Furthermore, before molding, both carbon fiber layers are resin pre-impregnated materials, using an epoxy resin system, and are stored under controlled temperature and humidity, exhibiting good workability and hot-press curing performance. During winding, the pre-impregnated carbon fiber layers are sequentially wrapped onto the mold core or the mandrel of the rod body 10 with relatively low tension. By precisely controlling the fiber bundle spacing and tension, the layup structure is ensured to be dense and less prone to air bubbles or delamination. Preferably, the ratio of the thickness of the first carbon fiber layer 20 to the thickness of the second carbon fiber layer 40 is 1:1.5 to 1:2.

[0023] Specifically, the composite braided layer 30 consists of multiple glass fibers interwoven at ±45° to the axis of the rod body 10 along its length, and multiple carbon fiber bundles parallel to the axis of the rod body 10 along its length. The carbon fiber bundles of the composite braided layer 30 are interwoven vertically between the interwoven glass fibers. More specifically, in this embodiment, the multiple glass fiber bundles of the composite braided layer 30, arranged at ±45° to the axis of the rod body 10 along its length, are woven in an upward and downward cross-weave pattern to form a structure similar to a plain weave. Multiple carbon fiber bundles, arranged parallel to the axis of the rod body 10, are placed within this cross-weave structure as longitudinal reinforcing fibers. During weaving, the carbon fiber bundles are interwoven at intervals between the upper and lower layers at the ±45° glass fiber intersections, forming a nested connection between multiple layers. At one intersection, the carbon fiber bundle is located below the oblique glass fiber braiding unit; as it extends to the next intersection unit, it passes from below to above, and so on. This interlacing method not only achieves effective connection between fibers in different directions, but also allows the entire composite structure to share stress simultaneously during longitudinal tension and oblique torsion, thereby improving the multi-bearing capacity and crack resistance of the rod body 10.

[0024] Specifically, the glass fiber tape layer 50 is woven from multiple glass fiber ribbons. Each glass fiber ribbon is composed of multiple parallel bundles of fine fibers, arranged uniformly and tightly, forming a ribbon-like structure with good flexibility and extensibility. In this application, the glass fiber ribbons are pre-impregnated with an epoxy resin system or bonded with resin to maintain a stable ribbon shape, preventing warping, wrinkling, or loosening during winding. When laid, the glass fiber tape layer 50 is spirally and uniformly wound around the outer surface of the second carbon fiber layer 40 at an angle of 15° to 30°, overlapping and tightly covering each other to form a continuous circumferential reinforcing band. This effectively improves the circumferential strength and surface wear resistance of the rod body 10, enhancing its structural stability and service life during repeated bending, impacts, and long-term use.

[0025] In this application, a glass fiber reinforcement layer 60 is disposed between the first carbon fiber layer 20 and the composite braided layer 30 of the central rod body 10. The glass fiber reinforcement layer 60 is made of high-density plain-weave glass fiber cloth and is disposed along the entire axial direction of the central rod body 10. It should be noted that the central rod body 10 determines the backbone strength of the rod body 10. Specifically, when the rod body 10 is configured with 5 sections, the central section is usually the 3rd section, located in the middle of the entire rod body structure. During stress, it plays a crucial role in connecting the upper and lower sections, transmitting stress, and controlling the bending amplitude. When the rod body 10 is configured with 4 or 6 sections, the central section that determines the backbone strength varies accordingly. Specifically, when the rod body 10 has a 4-section structure, the second section is usually located in the core stress-bearing area of ​​the entire rod body 10 (counting from the handle side). It is a key section for stress and force transmission in the waist area, serving as a transition connecting the sensitive front section and the support rear section. When the rod body 10 has 6 sections, either the third or fourth section can be used, depending on the required rod length. It should also be noted that the high-density plain-weave fiberglass cloth is woven from fiberglass yarns with uniform warp and weft density and consistent fiber diameter. That is, the warp and weft yarns are arranged alternately in an up-and-down manner, forming a uniformly interwoven "grid" structure, thus possessing excellent tensile strength and flexibility. This plain-weave fabric is axially laid in the fiberglass reinforcement layer 60, and through its synergistic effect with the other structural layers of the rod body 10, it effectively enhances the load-bearing capacity and deformation suppression ability of this rod section during stress.

[0026] Preferably, the ratio of interwoven glass fibers to carbon fiber bundles in the composite braided layer 30 is 1:1 to 2:1. More preferably, the ratio is 2:1, which allows the composite braided layer 30 to possess good multidirectional load-bearing capacity and axial rigidity.

[0027] Preferably, both the inner and outer sides of the glass fiber tape layer 50 are impregnated with epoxy resin layers. Specifically, before the glass fiber tape layer 50 is formed, the glass fiber tape is pre-impregnated with epoxy resin, and after the glass fiber tape layer 50 is wound, a thin epoxy film is applied to its outer surface, so that the glass fiber tape layer 50 is in a double-sided resin-coated state, which can enhance the wear resistance and anti-aging ability of the tape layer, and improve the stability and service life of the overall structure of the rod body 10.

[0028] Preferably, the rod body 10 is assembled with a telescopic structure or by plug-in connection.

[0029] This utility model provides a strong-backed fishing rod, including a rod body composed of multiple sections of rod body 10 connected in sequence, with the diameter of the rod body gradually decreasing from the handle to the tip. The rod body 10 is formed by a multi-layer structure, which includes, from the inside out, a first carbon fiber layer 20, a composite braided layer 30, a second carbon fiber layer 40, and a glass fiber tape layer 50. The first carbon fiber layer 20 and the second carbon fiber layer 40 in the rod body 10 are arranged parallel to each other along the axial direction of the rod body 10, thus providing the rod body 10 with good longitudinal tensile strength and basic support. The composite braided layer 30 is formed by multiple carbon fiber bundles interlaced with glass fibers at ±45° and parallel to the axis of the length direction of the rod body 10, giving the rod body 10 excellent torsional resistance and multi-directional force coordination. The outermost glass fiber tape layer 50 is spirally wound around the outside of the second carbon fiber layer 40, thereby improving the circumferential stability and crack resistance and wear resistance of the rod body. Furthermore, the glass fiber reinforcement layer 60 added to the middle section of the rod body 10 effectively enhances the bending load-bearing and rebound control capabilities of the waist area, thereby improving the "waist force" performance during fish handling. Therefore, this high-waist force fishing rod possesses excellent longitudinal strength, torsional rigidity, and flexibility, enabling it to maintain the stability of the rod body 10 when facing large, high-explosive fish, preventing deformation and quickly returning to its original shape. This improves fish handling precision and force application efficiency, making it well-suited for fishing scenarios requiring high "waist force" from the rod body 10.

[0030] 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.
