Description

Technical Field

[0001] The utility model relates to the technical field of fishing gear, in particular to a carbon fiber fishing rod. Background Art

[0002] Current carbon fiber fishing rods are typically manufactured using a hybrid of carbon fiber and glass fiber. This approach is driven by the fact that, while carbon fiber offers significant strength, it's primarily rigid, making it difficult to bend or deform, and prone to breaking when subjected to stress. To address this issue, existing carbon fiber fishing rods primarily utilize a hybrid of carbon fiber and glass fiber, sandwiching a layer of glass fiber between multiple layers of carbon fiber. This leverages the glass fiber's flexibility to complement the carbon fiber's rigidity. When the rod undergoes significant deformation, the glass fiber's filamentous structure restrains the carbon fiber, reducing the risk of breakage.

[0003] This hybrid fishing rod structure presents several issues. The first is increased weight, as glass fiber is heavier than carbon fiber for the same surface area, resulting in a heavier finished product. Second, the glass fiber is primarily composed of fine, velvety strands, similar to cotton velvet. This characteristic results in unstable and insensitive force transmission. For example, even the slightest vibration of the rod isn't transmitted quickly and accurately to the angler's hand, making it difficult for the angler to immediately sense whether a fish has taken the bait.

[0004] In order to solve the above problems, a new full carbon fiber structure is used to make the fishing rod, making it stronger and more sensitive. Utility Model Content

[0005] The purpose of the present invention is to solve the above defects and provide a carbon fiber fishing rod that can reduce the weight while ensuring its strength and toughness through a special carbon fiber arrangement structure, thereby solving one of the problems existing in the background technology.

[0006] The purpose of this utility model is achieved by the following methods:

[0007] A carbon fiber fishing rod includes a first inner layer made of carbon fiber, which is arranged axially. A second layer made of carbon fiber is provided above the first inner layer, and an angle is formed between the carbon fibers of the second layer and the first layer. A third layer is provided above the second layer, and the third layer is made of carbon fiber. The carbon fibers between the third layer and the second layer form an angle of 90 degrees. A fourth layer is provided on the third layer, and the carbon fibers of the fourth layer are provided in parallel with the carbon fibers of the first inner layer.

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

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

[0010] Furthermore, the carbon fibers in each layer are closely arranged.

[0011] The beneficial effects produced by the utility model are as follows: the inner and outer layers of carbon fibers are arranged in a straight line, which ensures that the fishing rod has a fast force transmission speed and is relatively sensitive, so that the angler can feel the slight vibration of the front end of the fishing rod; the angle design of the middle layer increases the force toughness of the fishing rod; and the angle design changes the vertical bending force into a torsional force with an angle, thereby enhancing the toughness of the fishing rod.

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0016] For ease of understanding, the present invention will be described in further detail with reference to specific implementation cases, but this is not intended to limit the present invention.

[0017] The technical principle of carbon fiber is that hair-like carbon fiber filaments are woven into carbon fiber cloth (similar to the weaving of cloth, with warp and weft interlaced) through weaving, which is then bonded and cured with resin, and then processed into various required shapes and structures (this technical solution is a mature existing technology and will not be described in detail here). Due to the inherent characteristics of carbon itself (not easy to deform, not able to stretch), it is prone to breakage when subjected to large forces. Therefore, in environments where toughness is required, all-carbon fiber is avoided and a glass fiber mixture is used. However, products such as fishing rods require a small weight and high sensitivity, and the fishing rods will also be subject to large bending forces. Therefore, there has been no good solution for using all-carbon fiber materials (without mixing glass fiber). The purpose of this utility model is to ensure that the fishing rod does not have a sandwich glass fiber interlayer, while still ensuring the toughness and sensitivity of the fishing rod.

[0018] Example 1 uses a four-layer structure, and the carbon fibers are not woven but laid flat, that is, all the carbon fibers are in a single direction, and each carbon fiber filament is tightly fitted to each other without crossing. The carbon fibers of the first inner layer 1 are arranged in a straight line, i.e., the length of the fishing rod. Above it is the second layer 2, which is also laid flat. The carbon fibers of the second layer 2 are arranged at an angle of 45 degrees to the carbon fibers of the first inner layer 1. The carbon fibers of the third layer 3 are arranged at an angle of 90 degrees to the carbon fibers of the second layer 2. The fourth layer 4, which is the outermost layer, is arranged along the length direction, just like the first inner layer 1.

[0019] The structural design of this fishing rod features an axially arranged inner and outer layers, ensuring the rod's sensitivity and enabling vibrations at the rod's front end to be quickly transmitted to the handle. The advantage of the angled design of the second and third layers is that when the rod's front end is subjected to significant force, the carbon fiber filaments of the first inner layer 1 and fourth layer 4, arranged axially, are subject to significant force and are susceptible to breakage. The angled design of the second and third layers, which wrap around the first inner layer 1 and fourth layer 4, reduces some of the force at an angle. Furthermore, their tightly wound and arranged arrangement provide partial support to the first inner layer 1 and fourth layer 4, enhancing toughness.

[0020] In Example 2, in order to further increase the bending strength of the fishing rod, the fifth, sixth, and seventh outer layers are added to achieve this goal. The arrangement angle of the fifth layer 5 is the same as that of the second layer 2, the arrangement angle of the sixth layer 6 is the same as that of the third layer 3, and the arrangement angle of the seventh outer layer 7 is the same as that of the first inner layer 1.

[0021] The above design features that the carbon fiber filaments between the innermost and outermost layers must be arranged in the axial direction. At the same time, to ensure the toughness of the carbon fiber filaments arranged in the straight direction, the carbon fiber filaments in adjacent layers need to be attached at a 45-degree angle. The adjacent layers that provide toughness support are arranged at a 90-degree angle, thereby achieving force support in different directions.

[0022] The manufacturing method of the embodiment of this technical solution is as follows:

[0023] 1. Manufacture carbon fiber cloth according to the specifications required by the embodiment.

[0024] 2. According to the length and size of the fishing rod and other information required, cut the carbon fiber cloth into trapezoidal or triangular blocks.

[0025] 3. Apply resin glue on the cylindrical iron core (fishing rod mold), prepare to wrap the carbon fiber cloth, and prepare for penetration and curing.

[0026] 4. Bond the cloth. Wrap the carbon fiber cloth around and bond it to the cylindrical iron core (fishing rod mold). Use a bending curling machine to wrap and compact the carbon fiber cloth (rub it on the iron core).

[0027] 5. Wrap a protective film (polypropylene film) around the outer surface of the semi-finished product in step 4 to protect its surface from damage.

[0028] 6. Bake and shape. Place the semi-finished product in step 5 into a 100-200 degrees Celsius oven and bake for about 2 hours. The resin glue solidifies at high temperature.

[0029] 7. Use a core-removing machine to separate the iron core from the carbon fiber fishing rod, forming a hollow fishing rod-like structure.

[0030] 8. Remove the protective film of the fishing rod-shaped structure to form the prototype of the fishing rod.

[0031] 9. The prototype of the fishing rod is ground, polished and painted to form the final fishing rod.

[0032] The fishing rod of Example 2 has been tested to obtain good results and compared with an existing glass fiber fishing rod of the same weight:

[0033] The test method adopts the average weighted method, and 5 samples of the prior art and 5 samples of this embodiment 2 are tested, and the average value of the test results of each sample is used as the comparison result.

[0034] The test contents are: vertical tensile test, reverse tensile test and vibration frequency test.

[0035] Vertical tensile test: The test method is to fix the head of the fishing rod to the floor with a fishing line, lift the handle position of the fishing rod in the vertical direction, and use the torque sensor to calculate the force state of the handle. Continue to lift until the fishing rod breaks and record the force value at the time of breakage.

[0036] Reverse pull test: The test method involves using a tensile tester to tie up the fishing line, which is connected to the rod head. The tester stands behind the rod handle and pulls the rod head in the opposite direction, causing the rod head to bend in the direction of the handle.

[0037] Vibration frequency test: Connect the vibration tester to the handle of the fishing rod, set a scale on the head of the fishing rod, and test the vibration speed at the same amplitude.

[0038] The test results are as follows:

[0039]

[0040] Test results show that this design improves the quality of fishing rods in all aspects, with sensitivity increased by 25%, vertical tension strength increased by more than 45%, and reverse tension increased by more than 60%. The structure of the present invention has significantly improved both strength and sensitivity.

[0041] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered as within the scope of protection of the present invention.
