Description

Support rod structure (II)

This work is about a supporting rod structure, especially one that has both radial and lateral strength and can maintain the integrity of its overall shape after processing.

For large-scale machinery and equipment, most of them use metal support frames to provide sufficient support strength. However, when assembling the metal support frame, if the metal support frame is large and the overall weight is too heavy, it may need to be suspended by a crane for construction. Not only is there a safety concern in the actual operation, but it also consumes a lot of electricity and wastes a lot of manpower during operation. Therefore, in order to have sufficient strength and reduce the weight of the product, the flat metal support plate will be replaced by a fiber plate. The current fiber plate is mainly formed by hardening a plurality of overlapping resin carbon fiber layers by heating and pressurizing. However, for the long solid fiber rod, in order to produce a precise shape and facilitate processing and molding to save costs, it is mainly formed by extrusion.

The main process of the extrusion molding process is to soak multiple long fibers in a resin tank, heat and harden them in a mold, and then draw them out. The extruded materials are then cut into finished products of various lengths according to the required size. Among them, since the extruded materials are made by uniaxial straight extrusion, although they have sufficient tensile strength and axial support, their strength in the horizontal direction perpendicular to the extrusion direction is obviously insufficient, relying only on the adhesion of the hardened resin. Furthermore, when the fiber rod is connected to machinery and equipment, it is often necessary to drill a hole on the fiber rod or cut at least one groove around the periphery. After drilling the hole or cutting the groove, part of the vertical fibers of the fiber rod will be cut off, which will weaken the function that originally relied on to form sufficient supporting strength, or cause part of the vertical fibers to fall off. This will not only affect the overall appearance, but also may weaken the strength of the fiber rod, making it unable to provide effective support and posing the risk of breaking.

In view of this, in order to provide a structure that is different from the commonly used technology and improve the above-mentioned shortcomings, the creators have accumulated many years of experience and continuous research and development and improvement, thus producing this creation.

One of the purposes of this invention is to provide a support rod structure to solve the problem that the solid fiber rod formed by drawing and extrusion has insufficient radial strength, or that after drilling and grooving on the fiber rod, some of the vertical fibers will be cut off and fall off, which will affect the overall appearance and make the fiber rod unable to effectively support or even have the risk of breaking. A woven fiber layer is fully integrated on the top surface or both the top and bottom surfaces of the fiber body, and the thickness of the woven fiber layer is between 0.5 and 5 mm, so as to increase the vertical and horizontal strength of the support rod; and when processing holes, grooves, etc., it can maintain the connection between the fibers and prevent some vertical fibers from falling off to maintain the integrity of the overall appearance. At the same time, it has sufficient supporting strength to ensure safe use.

In order to achieve the purpose of the above creation, the support rod structure of the creation has a first end and a second end in opposite directions, and a long rod body with a polygonal cross-section between the first end and the second end; its main technical features are: the long rod body includes a fiber body, and a first braided fiber layer is fully integrated on the top surface of the fiber body, and the thickness of the first braided fiber layer is between 0.5 and 5 mm.

During implementation, the cross-section of the long rod is a square.

In practice, the fiber body is a unidirectional fiber layer formed by extrusion.

In practice, the invention further comprises a second braided fiber layer, which is fully bonded to the bottom surface of the fiber body, and the thickness of the second braided fiber layer is between 0.5 and 5 mm.

During implementation, the long rod has at least one through hole penetrating the top surface and the bottom surface.

During implementation, one side surface of the long rod body has at least one groove penetrating the top surface and the bottom surface.

During implementation, the top surface of the long rod body has at least one blind hole penetrating the first braided fiber layer.

In order to further understand the invention, the following preferred embodiments are given, with diagrams and figure numbers to explain in detail the specific composition and effects of the invention as follows:

FIG. 1 and FIG. 2 are the first embodiment of the supporting rod structure 1 of the present invention, which has a first end 11 and a second end 12 in opposite directions, and a long rod 13 with a polygonal cross section between the first end 11 and the second end 12. In the present embodiment, the cross section of the long rod 13 is a square. In practice, the long rod 13 can also be a straight rod with a hexagonal or octagonal cross section. The long rod 13 includes a fiber body 14, which is a unidirectional fiber layer formed by a plurality of unidirectional long fibers 141 impregnated in a resin tank, heated and hardened in a mold, and then extruded. A first braided fiber layer 15 is fully stacked and glued on the top surface of the fiber body 14. The first braided fiber layer 15 includes a plurality of carbon fiber cloths stacked in sequence from top to bottom. The plurality of resin-containing carbon fiber cloths are hardened and formed after heating and pressurization. Each of the carbon fiber cloths includes a plurality of cross-woven carbon fibers 151. The thickness of the first braided fiber layer 15 is between 0.5 and 5 mm, so as to match the fiber body 14 to increase the vertical and horizontal strength of the support rod.

FIG. 3 and FIG. 4 are two other embodiments of the first embodiment of the support rod structure 1 of the present invention, wherein when the top surface of the long rod body 13 has at least one blind hole 131, or one side surface of the long rod body 13 has at least one short cut groove 132, the at least one blind hole 131 or the at least one short cut groove 132 respectively passes downward through the first woven fiber layer 15 and then partially enters the fiber body 15. The unidirectional long fibers 141 are partially cut off in the body 14; and the fibers of the first braided fiber layer 15 cross each other and downwardly bind the cut unidirectional long fibers 141 to form a comprehensive binding force, so that the cut unidirectional long fibers 141 will not fall off, thereby maintaining the integrity of the long rod body 13 and maintaining sufficient supporting strength to ensure safe use.

FIG. 5 and FIG. 6 are second embodiments of the support rod structure 1 of the present invention, which differs from the first embodiment in that: the bottom surface of the fiber body 14 is fully integrated with a second braided fiber layer 16, and the second braided fiber layer 16 is formed by heating and pressurizing a plurality of stacked resin-containing carbon fiber cloths, each of which includes a plurality of cross-woven carbon fibers 161; the thickness of the second braided fiber layer 16 is between 0.5 and 5 mm, so as to match the first braided fiber layer 15 and the fiber body 14 to further increase the vertical and lateral strength of the support rod.

FIG. 7 and FIG. 8 are two other embodiments of the second embodiment of the support rod structure 1 of the present invention, wherein when the long rod body 13 has at least one through hole 133 penetrating the top and bottom surfaces, or when one side surface of the long rod body 13 has at least one slot 134 penetrating the top and bottom surfaces, the at least one through hole 133 or at least one slot 134 respectively penetrates the first braided fiber layer 15, the fiber body 14, and the second braided fiber layer 16, while partially cutting off the fiber body 14. The unidirectional long fibers 141 of the fiber body 14 are intertwined with each other by the fibers of the first braided fiber layer 15 and the second braided fiber layer 16, and the cut parts of the unidirectional long fibers 141 are respectively combined, so that a comprehensive bonding force can be formed on the top and bottom surfaces of the fiber body 14 to prevent the cut parts of the unidirectional long fibers 141 from falling off, which can not only keep the top and bottom surfaces of the long rod body 13 intact, but also provide greater support strength to ensure safe use.

In summary, according to the contents disclosed above, this invention can achieve the expected purpose, providing a support rod structure that can not only increase the vertical and horizontal strength of the support rod, but also prevent part of the vertical fibers from falling off to maintain the integrity of the overall appearance when processing straight holes, grooves, etc., and at the same time has sufficient supporting strength to ensure safe use. It is extremely valuable for industrial use, and a patent application for the invention is filed in accordance with the law.
