Description

Technical Field

[0001] This utility model relates to the field of grip technology, and in particular to a carbon fiber grip. Background Technology

[0002] Fishing rods are essential tools for fishing enthusiasts. They are generally long and thin with a handle at the end, which is now mostly made of carbon fiber.

[0003] Generally, carbon fiber grips are made by gluing carbon fiber fabric to the outer surface of the inner core. Before gluing the carbon fiber fabric, it needs to be cut, which is a complicated process.

[0004] Therefore, the invention patent with application number 202010024733.4 discloses a fishing rod grip and its manufacturing method. By setting a high-temperature resistant inner core, it is not easily deformed during processing and manufacturing, and the grip feel is improved. However, the inner core is wrapped with carbon fiber cloth by winding, which usually adopts automated equipment. Before winding, the winding method needs to be designed according to the different shapes of the inner core. When producing grips of different shapes, multiple winding methods need to be designed, which is quite cumbersome. At the same time, the wrapping method of carbon fiber is generally limited to rectangular cylindrical structures or spindle-shaped cylindrical structures. For complex structures such as dumbbell-shaped structures, the winding method is difficult to achieve good results. Utility Model Content

The warp and weft threads of the carbon fiber braided sleeve are not parallel to the axis of the carbon fiber braided sleeve, and the warp and weft threads are woven to form a parallelogram. The carbon fiber braided sleeve can be stretched and deformed axially and radially through the deformable properties of the parallelogram. Through the deformation of the carbon fiber braided sleeve, it can be tightly fitted to the outer surface of the inner core.

[0008] As a preferred embodiment, the warp and weft threads have a twill pattern with two overlapping threads.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0025] Example 1

[0026] like Figure 1-3As shown, this utility model discloses a carbon fiber grip, including an inner core 10. The inner core 10 has an axially penetrating through hole 11, which is used to fit various rod-shaped structures, such as fishing rods, badminton clubs, or golf clubs. A carbon fiber braided sleeve 20 is fitted onto the outer surface of the inner core 10. The warp 21 and weft 22 of the carbon fiber braided sleeve 20 are not parallel to the axis of the carbon fiber braided sleeve 20, and the warp 21 and weft 22 are woven to form a parallelogram. The carbon fiber braided sleeve 20 can expand and contract axially and radially due to the deformable properties of the parallelogram. Through the deformation of the carbon fiber braided sleeve 20, it can fit tightly against the outer surface of the inner core 10, such as... Figure 3 As shown, the solid parallelograms represent the carbon fiber braided sleeve 20 stretching axially and contracting radially, while the dashed parallelograms represent the carbon fiber braided sleeve 20 contracting axially and radially. The carbon fiber cloth winding inner core 10 is generally only suitable for spindle-shaped grips and straight handle grips. However, with the stretchable and deformable carbon fiber braided sleeve 20, it can be used to produce grips of various shapes without the need to set a winding method. The grip forming process is simple, which is convenient for mass production and can also meet the needs of private customization.

[0027] The inner core 10 is an elastic inner core, and the material of the inner core 10 is polyurethane foam, polyolefin elastomer, or ethylene-vinyl acetate copolymer. The inner core 10 and the carbon fiber braided sleeve 20 are cured together with resin adhesive 30.

[0028] In this embodiment, the material of the inner core 10 is polyurethane foam. In practical applications, the inner core 10 is not limited to polyurethane foam, but can also be polyolefin elastomer or ethylene-vinyl acetate copolymer.

[0029] The angle α between the meridian 21 and the parallel 22 is 30° to 150°.

[0030] In this embodiment, the angle α between the warp 21 and the weft 22 is 45°, at which point the carbon fiber braided sleeve 20 is in an initial state of radial contraction and axial elongation.

[0031] In practical applications, the angle α between meridian 21 and the axis is not limited to 45°, but can also be 30°, 60°, or 90°. An angle of 45° is the preferred choice in this embodiment.

[0032] The warp and weft threads 21 and 22 are in a twill pattern with two overlapping threads (see reference). Figure 2The warp 21 and weft 22 are interlaced in a stepped pattern of "two up and two down" to form a diagonal texture. There are fewer interlacing points, and two consecutive yarns are not interlaced. The yarn float is longer, the space for movement is larger, and it is easier to stretch. This makes the carbon fiber braided sleeve 20 have better elasticity and extensibility. The diagonal structure makes the carbon fiber braided sleeve 20 softer and more wear-resistant, and makes the formed carbon fiber grip more beautiful.

[0033] The manufacturing steps for the above carbon fiber grips are as follows:

[0034] Step 1: Grind the polyurethane foam into the required shape and length, leaving extra length on both sides for cutting the top flat.

[0035] Step 2: Apply a uniform layer of resin adhesive 30 (mixed with acetone in a 2:1 ratio) to the sanded polyurethane foam.

[0036] Step 3: Let the polyurethane foam coated with resin adhesive 30 stand for 6-10 hours to dry until the resin adhesive 30 is no longer sticky to the touch.

[0037] Step 4: After the resin adhesive has dried for 30 minutes, fit the polyurethane foam into a 20mm carbon fiber braided sleeve.

[0038] Step 5: After the polyurethane foam is fitted with the carbon fiber braided sleeve 20, the carbon fiber braided sleeve 20 is pulled axially to make it fit tightly against the polyurethane foam, and then the carbon fiber braided sleeve 20 is straightened.

[0039] Step Six: Secure the carbon fiber braided sleeve 20 to both ends of the polyurethane foam with cable ties, and cut off any excess cable ties to form the carbon fiber grip.

[0040] Step 7: Apply a layer of resin adhesive evenly to the surface of the carbon fiber grip.

[0041] Step 8: Let the carbon fiber handle, after applying 30g of resin glue, air dry until it is no longer sticky.

[0042] Step 9: Place the dried carbon fiber handles into the oven and bake at 125-145°C for 20-30 minutes.

[0043] Step 10: Remove the baked carbon fiber grip from the oven, cut and flatten it as required, and polish the grip surface.

[0044] In step four, the ends of the carbon fiber braided sleeve 20 are unsealed. When fitting the carbon fiber braided sleeve, the unsealed carbon fiber braided sleeve 20 must be deformed so that its diameter is larger than the maximum diameter of the inner core 10, so that it can be easily fitted onto the outer surface of the inner core 10. The ends of the carbon fiber braided sleeve 20 are tightened axially to elongate the carbon fiber braided sleeve 20 axially. At the same time, the carbon fiber braided sleeve 20 contracts radially to fit tightly against the outer surface of the inner core 10.

[0045] The warp 21 is composed of several strands of carbon fiber single yarn, and the weft 22 is composed of several strands of carbon fiber single yarn.

[0046] The warp yarn 21 has 3K-6K plies, the weft yarn 22 has 3K-6K plies, the warp yarn 21 has a yarn count of 200-1200D, and the weft yarn 22 has a yarn count of 200-1200D.

[0047] In this embodiment, in order to make the carbon fiber braided sleeve 20 have better elasticity and extensibility, the number of plies of the warp 21 is 3K, the number of plies of the weft 22 is 3K, the yarn count of the warp 21 is 300D, and the yarn count of the weft 22 is 300D. This yarn specification is the preferred choice in this embodiment. In actual application, the number of plies of the warp 21 and the weft 22 is not limited to 3K, but can also be 6K, and the yarn count of the warp 21 and the weft 22 is not limited to 300D, but can also be 600D.

[0048] Example 2

[0049] like Figure 3 As shown, the difference between this embodiment and the above embodiment is that the warp 21 and weft 22 are a plain weave structure with one thread pressing against the other, which has a high interlacing density, short float length, and a tight structure.

[0050] The carbon fiber grip of this invention is not limited to fishing rod grips, but can also be used for golf club grips and other grips.

[0051] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
