Description

Technical Field

[0001] The utility model relates to the technical field of bow and arrow accessories, in particular to an arrow shaft with strong balance. Background Art

[0002] Traditional arrow shafts are mostly made of wood, aluminum, and fiberglass, and they have different defects during use. For example, the uneven mass distribution of wooden arrow shafts affects linearity; while aluminum arrow shafts overcome the defects of wooden arrow shafts, but due to their poor rigidity, they are prone to bending and other deformation during use.

[0003] In recent years, with the rise of carbon fiber composite materials, people have begun to use them on arrow shafts. However, due to the immaturity of related technologies, the impact strength and bending strength of current carbon fiber arrow shafts are still not high enough, resulting in the arrow shafts being easily broken during use.

[0004] In addition, due to the low bending strength of the arrow shaft, the arrow shaft has poor stability during flight.

[0005] Therefore, the arrow shaft in the prior art has the technical problems of poor stability and low bending strength. Summary of the invention

[0006] The utility model provides an arrow shaft with strong balance, which solves the technical problems of poor stability and low bending strength of the arrow shaft in the prior art.

At the same time, due to the setting of the inner rod, outer rod and supporting ribs, the arrow shaft has a higher bending strength as a whole, and the arrow shaft is not easy to bend and deform during flight, thereby improving the stability of the rib rod.

[0022] 2. An airflow channel is formed between the inner rod and the outer rod. Part of the airflow flows through the airflow channel during the flight of the arrow shaft. The airflow channel can improve the stability of the arrow shaft during flight, and cooperate with the arrow feathers to make the arrow shaft well balanced during flight.

[0023] 3.
