Description

[Technical field]

[0001] The present invention relates to the field of fishing tackle technology, and in particular to carbon fiber fishing rods. [Background technology]

[0002] Conventional carbon fiber fishing rods generally adopt the mixed manufacturing technology of carbon fiber and glass fiber, the reason for adopting such a technical means is that carbon fiber has high strength, but mainly exhibits rigidity, which is difficult to bend and deform, and is easily broken when subjected to force. To solve this problem, conventional carbon fiber fishing rods mainly adopt the mixed method of carbon fiber and glass fiber, that is, one layer of glass fiber is interposed between multiple layers of carbon fiber, combining the flexibility of glass fiber and the rigidity of carbon fiber, when the fishing rod is severely deformed, the thread-like structure of glass fiber is used to bind the carbon fiber, reducing the risk of the fishing rod breaking.

[0003] There are several problems with fishing rods with this type of mixed structure. One is that the weight of the fishing rod increases. With the same area, the weight of glass fiber is greater than that of carbon fiber, so the weight of the product increases. Another is that the main component of glass fiber is similar to the structure of fine strips of velvet and cotton velvet, and due to this characteristic, the transmission of force is unstable and not sensitive. For example, the slight vibration of the fishing rod is not transmitted to the hand quickly and accurately. The angler cannot immediately feel whether a fish is hooked.

[0004] To solve the above problems, a new all-carbon fiber construction is used to manufacture the fishing rod, which makes it stronger and more sensitive. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to solve the above-mentioned shortcomings, the present invention aims to provide a carbon fiber fishing rod, which uses a special carbon fiber arrangement structure to ensure strength and toughness while reducing weight, thereby solving one of the problems existing in the background art. [Means for solving the problem]

[0006] The object of the present invention is achieved as follows:

[0007] A carbon fiber fishing rod comprising a first inner layer made of carbon fiber, the carbon fibers of the first inner layer being aligned along an axial direction, a second layer made of carbon fiber being disposed on top of the first inner layer, the carbon fibers of the second layer forming an angle with the carbon fibers of the first layer, a third layer being disposed on top of the second layer, the third layer being made of carbon fiber and forming a 90 degree angle with the carbon fibers of the second layer, and a fourth layer being disposed on top of the third layer, the carbon fibers of the fourth layer being parallel to the carbon fibers of the first inner layer.

[0008] Furthermore, a fifth layer of carbon fiber is further provided on the fourth layer, where the arrangement angle of the carbon fiber of the fifth layer is parallel to the arrangement angle of the carbon fiber of the second layer, a sixth layer of carbon fiber is further provided on the fifth layer, where the arrangement angle of the carbon fiber of the sixth layer is parallel to the arrangement angle of the carbon fiber of the third layer, and a seventh layer of carbon fiber is further provided on the sixth layer, where the arrangement angle of the carbon fiber of the seventh layer is parallel to the arrangement angle of the carbon fiber of the fourth layer.

[0009] Additionally, the angle between the first inner layer and the second layer of carbon fiber is 45 degrees.

[0010] Furthermore, the carbon fibers in each layer are tightly packed together. Effect of the Invention

[0011] The beneficial effects of this invention are as follows: the carbon fiber of the inner and outer layers is linearly arranged, which ensures that the fishing rod has a fast and sensitive force transmission speed, allowing the angler to feel the slightest vibration at the tip of the rod; the angle design of the middle layer increases the rod's force-bearing toughness; the angle design transforms the vertical bending force into an angular torsional force, improving the toughness of the fishing rod. [Brief description of the drawings]

[0013] The present invention will be described in more detail below in combination with the drawings and specific embodiments.

[0014] For ease of understanding, the present invention will now be described in more detail in combination with specific implementation means, which are not used to limit the present invention.

[0015] The technical principle of carbon fiber is that hair-like band-like carbon fiber threads are woven (similar to the weaving method of fabric, where the warp and weft are interwoven) into carbon fiber cloth, which is then bonded and hardened with resin, and then processed into various shapes and structures as required (this technical method is a mature conventional technology and will not be described in detail here). Due to the inherent properties of carbon itself (difficult to deform, no ability to stretch), it is prone to breakage when subjected to a large force, so in environments where toughness is required, a method of mixing glass fiber is used instead of all carbon fiber. However, fishing rod products are required to be light in weight and highly sensitive, while at the same time the fishing rod must be able to withstand a large bending force, so there has been no good way to use all carbon fiber material (without mixing glass fiber). The purpose of this invention is to ensure the toughness and sensitivity of the fishing rod even if the fishing rod does not have a middle layer of glass fiber.

[0016] In the first embodiment, a four-layer structure is used, and the carbon fibers are not woven, but are arranged in a single direction, with each carbon fiber thread closely spaced and flattened so that they do not cross. The carbon fibers of the first inner layer 1 are arranged in a straight line, i.e., along the length of the fishing rod. The second layer 2 is provided on the first inner layer 1, and the second layer 2 is also flattened, with the carbon fiber threads of the second layer 2 and the first inner layer 1 arranged at a 45 degree angle. The carbon fiber threads of the third layer 3 and the carbon fiber threads of the second layer 2 are arranged at a 90 degree angle. The fourth layer 4, the outermost layer, is arranged along the length, just like the first inner layer 1.

[0017] The special feature of this structural design of the fishing rod is that the inner and outer layers are arranged along the axial direction, which ensures the sensitivity of the fishing rod and can quickly transmit the vibration of the tip of the fishing rod to the handle position. The advantage of the angle design of the second and third layers is that when the tip of the fishing rod is subjected to a large force, the carbon fiber threads of the first inner layer 1 and the fourth layer 4 are arranged along the axial direction, so that the force is large and easy to break. However, the angle design of the second and third layers surrounds the first inner layer 1 and the fourth layer 4 correspondingly, and further resolves part of the force at the angle, and is tightly wound and arranged, which provides some support to the first inner layer 1 and the fourth layer 4, thereby enhancing the toughness.

[0018] In the second embodiment, in order to further increase the bending force of the fishing rod, the fifth, sixth and seventh outer layers are added to achieve this purpose. The fifth layer 5 has the same arrangement angle as the second layer 2, the sixth layer 6 has the same arrangement angle as the third layer 3, and the seventh outer layer 7 has the same arrangement angle as the first inner layer 1.

[0019] The special feature of the above design is that the carbon fiber yarns in the innermost and outermost layers must be aligned along the axial direction, and at the same time, in order to ensure the toughness of the linearly aligned carbon fiber yarns, they must be closely spaced at a 45 degree angle from the carbon fiber yarns in the adjacent layers.The adjacent layers that provide toughness support are aligned at a 90 degree angle, thereby realizing load bearing support in different directions.

[0020] The manufacturing method of the embodiment of this technical means is as follows.

[0021] 1. Manufacture carbon fiber cloth according to the required specifications of the embodiment. 2. According to the requirements of the information such as the length and size of the fishing rod, the carbon fiber fabric is sheared into trapezoidal or triangular blocks. 3. A resin adhesive is applied to a cylindrical mandrel (fishing rod mold) and carbon fiber cloth is wrapped around it in preparation for infiltration and curing. 4. The fabric is attached, and the carbon fiber fabric is wrapped around a columnar mandrel (fishing rod mold) to glue it, and then the carbon fiber fabric is wrapped and compressed with a rolling machine (tightly wrapped around the mandrel). 5. Wrap a protective film (polypropylene film) around the outer surface of the semi-finished product in step 4 to protect the outer surface from damage. 6. Roasting and molding, the semi-finished product of step 5 is placed in a 100-200℃ oven and baked for about 2 hours, and the resin adhesive is hardened under high temperature. 7. The mandrel is removed from the carbon fiber fishing rod using a corer to form a hollow fishing rod-like structure. 8. Remove the protective film from the fishing rod-shaped structure to form a fishing rod template. 9. The fishing rod template is polished, buffed and painted to form the final fishing rod.

[0022] The fishing rod of Example 2 was tested and showed good results, and a comparative test was carried out with a fishing rod containing a conventional glass fiber of the same weight. The test method adopts the average weighting method, in which five conventional technology samples and five samples of the present embodiment 2 are tested, and the average value of the test results of each sample is taken as the comparison result.

[0023] The tests consisted of a vertical tension test, a reverse tension test and a vibration frequency test.

[0024] Vertical tension test: The test method is as follows: the head of the fishing rod is fixed to the floor with a fishing line, and the handle of the fishing rod is raised vertically. At the same time, a torque sensor is used to calculate the force-bearing state of the handle. The fishing rod is continued to be raised until it breaks, and the force-bearing value at the time of breakage is recorded.

[0025] Reverse tension test: The test method is as follows: the fishing line is tied with a tension meter and connected to the head of the fishing rod. The subject stands behind the handle of the fishing rod and pulls the head of the fishing rod in the reverse direction, so that the head of the fishing rod is subjected to a force in the reverse direction and bends toward the handle.

[0026] Vibration frequency test: The vibration measuring instrument is connected to the handle of the fishing rod and a scale is placed on the head of the fishing rod to test the vibration speed at the same amplitude.

[0027] The test results are as follows:

[0028] [Table 1]

[0029] Test results show that this design improves the quality level of the fishing rod in each aspect, improving sensitivity by 25%, vertical tension strength by more than 45%, and reverse tension by more than 60%. It can be seen that the structure of the present invention can significantly improve both strength and sensitivity.

Those skilled in the art can make some simple derivations or substitutions without departing from the concept of the present invention, and all of them should be considered as part of the protection scope of the present invention.
