Description

Technical Field

[0001] This utility model relates to the field of arrow shaft technology, specifically to a carbon fiber arrow shaft. Background Technology

[0002] The arrow shaft is the main part of the arrow, usually made of materials such as wood, aluminum alloy, or fiberglass. Its primary function is to support the arrow, ensuring its stability and accuracy during flight. The design of the arrow shaft needs to consider several factors, including straightness, strength, and deflection. Straightness refers to the straightness of the shaft, directly affecting the arrow's flight trajectory; strength and toughness ensure the arrow is not easily broken during flight; deflection refers to the shaft's stiffness or flexibility, and appropriate deflection allows the arrow to better correct its trajectory during flight.

[0003] However, the existing arrow shafts have poor straightness. When used outdoors, the wind often causes the arrow to bend and swing, and the deflection is difficult to meet the needs of the arrow during use. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a carbon fiber arrow shaft. By covering the outer surface of the arrow shaft with carbon fiber layers of varying thicknesses to form an integrated structure, the deflection of the arrow shaft is adjusted to meet the needs of adjusting the arrow's attitude when flying in the wind. On the other hand, the influence of air resistance on the arrow's flight trajectory is reduced, further decreasing the swing amplitude of the arrow during flight, thereby improving the accuracy of archery.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a carbon fiber arrow shaft, comprising a shaft body and a carbon fiber layer covering the outside of the shaft body, wherein the carbon fiber layer comprises a head section, a curved transition section one, a straight middle section, a curved transition section two, and a tail section connected in sequence, wherein the tail section is connected with arrow fletching, and the head section is provided with an arrowhead.

[0006] The length of the head segment is a, the length of the straight middle segment is b, and the length of the tail segment is c, where b > a > c.

[0007] The outer diameter of the straight middle section is d2, and the outer diameter of the head section is d1, where d2 / d1 > 1.

[0008] The outer diameter of the tail section is d3, where d3 ≤ d1.

[0009] The rod is made of polymer fibers wound together, and the polymer fibers are one of carbon fiber, aramid fiber, and nylon fiber.

[0010] The carbon fiber layer is wrapped around the outer surface of the rod in an integral structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) During use, the shaft is made of one of carbon fiber, aramid fiber or nylon fiber, which is stronger and lighter, meeting the strength and toughness requirements of the arrow during use, avoiding damage to the shaft when it is impacted, and making the shaft more durable.

[0013] (2) By covering the outer surface of the arrow shaft with carbon fiber layers of different thicknesses to form an integrated structure, the deflection of the arrow shaft is adjusted to meet the needs of adjusting the attitude of the arrow when flying in the wind. On the other hand, since the carbon fiber layer includes the head section, the first curved transition section, the straight middle section, the second curved transition section and the tail section connected in sequence, it is more in line with the principle of aerodynamics, increases the ability of the arrow shaft to overcome air resistance during flight, can pass through the air more effectively, reduces the influence of air resistance on the flight trajectory of the arrow, further reduces the swing amplitude of the arrow during flight, and thus improves the accuracy of shooting.

[0017] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0018] See Figure 1 , Figure 2 A carbon fiber arrow shaft includes a shaft body 1 and a carbon fiber layer 2 covering the outside of the shaft body 1. The carbon fiber layer 2 includes a head section 21, a curved transition section 1 22, a straight middle section 23, a curved transition section 24 and a tail section 25 connected in sequence. The tail section 25 is connected with arrow feathers, and the head section 21 is provided with an arrowhead.

[0019] Furthermore, the length of the head segment 21 is a, the length of the straight middle segment 23 is b, and the length of the tail segment 25 is c, where b > a > c.

[0020] Both the head segment 21 and the tail segment 25 are cylindrical. The outer diameter of the straight middle segment 23 is d2, and the outer diameter of the head segment 21 is d1, where d2 / d1 > 1.

[0021] The outer diameter of the tail section 25 is d3, where d3 ≤ d1.

[0022] The rod body 1 is made of polymer fiber winding, which is one of carbon fiber, aramid fiber, nylon fiber, or other polymer fiber wires wound together.

[0023] Furthermore, the carbon fiber layer 2 is integrally formed by covering the outer surface of the rod body 1. More specifically, the carbon fiber layer 2 is integrally formed by covering the rod body 1 along its length. The covering direction of the carbon fiber layer 2 is described in [reference needed]. Figure 2 This makes the arrow shaft more robust and increases the strength of the arrow body.

[0024] The specific working process of this utility model:

[0025] When the arrow is driven by the tail, the force is transmitted through the curved transition section 24 to the entire shaft and then to the whole arrow body. The force on the arrow body is more balanced. Since the outer diameter of the straight middle section 23 is much larger than the outer diameter of the head section 21 and the tail section 25, the deflection of the arrow when it is shot is greatly reduced, ensuring that the arrow shaft flies stably in an appropriate posture during flight and corrects the flight trajectory in time, so as to accurately hit the target.

[0026] During use, the shaft 1 is made of one of carbon fiber, aramid fiber, or nylon fiber, which is stronger and lighter, meeting the strength and toughness requirements of the arrow during use, avoiding damage to the shaft when it is subjected to impact, and making the shaft more durable.

[0027] By wrapping the outer surface of the arrow shaft with carbon fiber layers 2 of different thicknesses to form an integrated structure, the deflection of the arrow shaft is adjusted to meet the needs of adjusting the arrow's attitude when flying in the wind. On the other hand, since the carbon fiber layer 2 includes the head section 21, the curved transition section one 22, the straight middle section 23, the curved transition section two 24 and the tail section 25 connected in sequence, it is more in line with the principles of aerodynamics, increases the arrow shaft's ability to overcome air resistance during flight, can more effectively pass through the air, reduces the impact of air resistance on the arrow's flight trajectory, further reduces the swing amplitude of the arrow during flight, and thus improves the accuracy of shooting.

[0028] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
