Description

  The present invention relates to the technical field of pipe materials, and more particularly to a hollow fiber pipe that can be widely applied to the field of exercise equipment.

  The hollow fiber pipe is one of the main pipe materials for manufacturing the racket frame. This type of pipe includes a hollow tube. Since the hollow tube body is adopted, the completed racket frame is relatively light weight, the user can use it easily, and the playing technique can be fully exhibited.

  At present, the wall thickness of the hollow fiber pipe is uniform and there is no particular change. However, in the actual use process, it has been clarified that the racket manufactured with the hollow fiber pipe has the following various defects.

The vibration and impact become large, and it is not suitable for the user to handle the racket comfortably. Since it is heavy overall, it is inconvenient for the user to manipulate the racket flexibly, and the user tends to feel a sense of fatigue. Since the structural strength is insufficient, even the phenomenon that the racket is bent and deformed occurs, which affects the service life of the racket.
The present invention has been made in view of the above-described drawbacks of conventional hollow fiber pipes.

By integrally molding a large number of reinforcing ribs on the inner wall of the through hole, the strength of the present invention is greatly enhanced. The pipe body becomes denser, not only can the overall strength of the present invention be further strengthened, but also the use of fiber cloth can be saved, the material can be saved, the production cost can be reduced, and the product can also be reduced in weight. Therefore, the user can obtain a better hit feeling.

It is radial direction sectional drawing of 1st embodiment of this invention. It is a local exploded solid view of the first embodiment of the present invention. It is a local exploded three-dimensional view of the second embodiment of the present invention. It is a local exploded view of a third embodiment of the present invention. It is a local exploded view of a fourth embodiment of the present invention.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the first embodiment of the present invention includes a fiber pipe body 10. The fiber pipe body 10 is hollow and forms a through hole 11.
A number of reinforcing ribs 12 are integrally formed on the inner wall of the through hole 11. A foam material layer 13 is installed in each reinforcing rib 12. The foam material layer 13 is formed by foaming and solidifying a powder or granular foam material.

  Moreover, in the present embodiment, the reinforcing rib 12 includes a large number of first reinforcing ribs 121 and a large number of second reinforcing ribs 122. Each first reinforcing rib 121 extends in the axial direction toward the center of the fiber pipe body 10 at one end of the through hole 11. Each second reinforcing rib 122 extends in the axial direction toward the center of the fiber pipe body 10 at the opposite end of the through hole 11. In addition, many first reinforcing ribs 121 and many second reinforcing ribs 122 face each other in front of each other. The heights H of the multiple first reinforcing ribs 121 and the multiple second reinforcing ribs 122 are uniform and equal.

  At the time of manufacture, a mold core having a groove on the surface is adopted, and a fiber cloth is wound around the surface of the mold core. At the same time, a foam material is installed on the fiber cloth surface corresponding to the groove at the appropriate time. After winding the fiber cloth, the mold core is placed in a mold and solidified. After solidification, the mold core is taken out to complete the production of the present invention.

  As shown in FIG. 3, the structure of the second embodiment of the present invention is basically the same as the structure of the first embodiment described above, but the differences will be described below. In the present embodiment, since the plurality of first reinforcing ribs 121 and the plurality of second reinforcing ribs 122 are not front-facing installations, the structural strength of the present invention can be made more uniform.

  The manufacturing process of this example and the manufacturing process of the first embodiment described above are basically homologous, and the differences will be described below. In this embodiment, two corresponding connection mold cores are employed. After the fiber cloth is solidified, the two correspondingly connected mold cores are taken out and completed.

  As shown in FIG. 4, the structure of the third embodiment of the present invention and the structure of the first embodiment described above are basically homologous, and the differences will be described below. During the implementation, the first reinforcing ribs 121 and the second reinforcing ribs 122 are installed with their positions shifted from each other, so that the structural strength of the present invention can be made even more uniform. Further, the overall strength can be further increased. Since the manufacturing process of this example and the manufacturing process of the second embodiment described above are basically similar, the manufacturing process of this example will not be described in detail here.

  As shown in FIG. 5, the structure of the fourth embodiment of the present invention and the structure of the first embodiment described above are basically homologous, and the differences will be described below. During this implementation, the height H of each first reinforcing rib 121 and the height H of each second reinforcing rib 122 both decrease from the outer end to the inner end. Thereby, the structure of both ends of the present invention can be further strengthened, and at the same time, the material can be saved. Since the manufacturing process of this example and the manufacturing process of the second embodiment described above are basically similar, the manufacturing process of this example will not be described in detail here.

  The emphasis on the design of the present invention is described below. By integrally molding a large number of reinforcing ribs 12 on the inner wall of the through hole, the strength of the present invention is greatly increased, and by simultaneously installing the foam material layer 13 in each reinforcing rib, the foam material layer is pressed, The fiber pipe body becomes denser, not only can the overall strength of the present invention be further strengthened, but also the use of fiber cloth can be saved, the material can be saved, the production cost can be reduced, and the product can also be reduced in weight Therefore, the user can obtain a better feeling of hitting.

  The names and contents of the present invention described above are only used for explaining the technical contents of the present invention, and do not limit the present invention. All equivalent applications based on the spirit of the present invention, parts (structures) conversion, replacement, and quantity increase / decrease shall be included in the protection scope of the present invention.
