Description

Support rod structure (1)

The invention relates to a support rod structure, especially one that can simultaneously have radial strength and sufficient support strength to ensure safe use.

For large-scale machinery and equipment, metal support frames are mostly used to provide sufficient support strength. However, when assembling metal support frames, if the metal support frame is too large to make the overall weight too heavy, it may be necessary to hang it with a crane. Crane construction not only has safety doubts in actual operation, but also consumes electricity and wastes manpower during operation. Therefore, for the planar metal support plate, in order to have sufficient strength and reduce the weight of the product, the metal support plate will be replaced by fiberboard, and the current fiberboard mainly uses heating and pressure. However, for solid strip products, especially cylindrical fiber rods, in order to produce precise shapes and facilitate processing and molding to save costs, pultrusion is mainly used The processing method is pultrusion.

The pultrusion molding processing method is mainly to impregnate a plurality of long fibers from the resin tank, enter the mold, heat and harden, and then pull them out. After the molding, the pultrusion profile is cut into various lengths according to the required size. Among them, since the pultrusion profile is uniaxially pultruded, although it has sufficient tensile strength and axial support, it only relies on the adhesive force of the hardened resin in the radial direction perpendicular to the pultrusion direction. , its strength is obviously insufficient. Furthermore, when the fiber rod is upwardly connected to the equipment, it is often necessary to cut at least one annular groove on the periphery of the fiber rod, and when the annular groove is cut, the part of the fiber rod will be cut off straight to the fiber, allowing the original The function of forming sufficient support strength is weakened, or the straight fiber between the end of the fiber rod and the annular groove is peeled off; this will not only affect the overall shape, but may also make the fiber rod unable to effectively support upwards, And there is a danger of breaking.

In view of this, in order to provide a structure different from the conventional technology and improve the above-mentioned shortcomings, the author has accumulated many years of experience and continuous research and development, so this creation is produced.

One purpose of this creation is to provide a support rod structure to solve the lack of radial strength of conventional pultruded materials, or to cut off part of the straight fibers after processing such as annular grooves on the periphery of the fiber rod , so that the straight fibers between the end of the fiber rod and the annular groove are peeled off, which will affect the overall shape, and at the same time make the fiber rod unable to effectively support upwards, and even have the risk of breaking, but can pass through multiple fiber layers The upper and lower layers are bonded together to form a fiber body, and at least one fiber body constitutes a rod structure to increase the radial strength of the support rod; and when processing such as annular grooves, the connection between the fibers can be maintained. Prevent fiber peeling to maintain the integrity of the overall shape, and at the same time have sufficient support strength to ensure safe use.

In order to achieve the purpose of the above creation, the support rod structure set up in this creation has a first end and a second end in reverse, and there is a rod body between the first end and the second end; its main technical characteristics are: The outer periphery of the rod body has at least one arc surface, and at least one arc surface extends axially from the first end toward the second end; and the rod body includes at least one fiber body, and the fiber body includes a vertical fiber layer that is overlapped and bonded up and down, A transverse fiber layer, a first oblique fiber layer and a second oblique fiber layer, the fibers of the straight fiber layer are parallel to the axial direction of the rod body, the fibers of the transverse fiber layer are parallel to the radial direction of the rod body, the first Each fiber of the oblique fiber layer and each fiber of the second oblique fiber layer have an angle with the axial direction of the rod body, and each fiber of the first oblique fiber layer and each fiber of the second oblique fiber layer cross each other .

During implementation, the cross section of the rod body is circular.

During implementation, the vertical fiber layer, the transverse fiber layer, the first oblique fiber layer and the second oblique fiber layer are sequentially overlapped and bonded from top to bottom.

During implementation, the rod body includes two fiber bodies stacked and bonded up and down, and the two fiber bodies respectively have a vertical fiber layer, a transverse fiber layer, a first oblique fiber layer and a second oblique fiber layer arranged in the same direction up and down.

During implementation, the rod body includes two fiber bodies stacked and bonded up and down, and the two fiber bodies respectively have a vertical fiber layer, a transverse fiber layer, a first oblique fiber layer and a second oblique fiber layer arranged in reverse up and down.

During implementation, the periphery of the rod body has at least one annular recess.

In this way, the mutual bonding of each intersecting fiber ( 21 , 31 , 41 , 51 ) through each fiber layer can not only generate sufficient supporting strength, but also increase the radial strength of the rod body 13 .
