Description

Technical Field

[0001] This utility model relates to the field of bow wheel technology, specifically an integrated double-string groove bow wheel. Background Technology

[0002] Compound bows are widely used in archery competitions and training. With the increasing popularity of archery, compound bows are also gaining more and more public attention, becoming a new form of leisure and entertainment. A compound bow mainly consists of a handle assembly, limbs, and a bow wheel assembly. By holding the handle with one hand and drawing back the bowstring between the bow wheels with the other, the energy stored in the deformed bow wheel assembly is converted into the arrow's kinetic energy, allowing the arrow to be shot quickly and accurately towards the target.

[0003] The existing publication number CN222938366U discloses a composite bow with an integrated main string, including a bow body. A first bow wheel and a second bow wheel are respectively mounted on both ends of the bow body via bow plates. Two secondary strings are installed between the first and second bow wheels. The main string, which has a ring structure, is installed between the first and second bow wheels. The ring structure of the main string provides a high degree of freedom and convenient adjustment. Hooks are provided between two guide grooves on the bow wheel body. The two ends of the main string are suspended from the corresponding hooks after passing through the main string grooves of the first and second bow wheels. This method eliminates the need for the two ends of the main string to be fixed, allowing for free movement and better adjustability.

[0004] The existing bow wheel has two separate string grooves, which results in a thicker and heavier bow wheel, inevitably leading to a relatively slower bow wheel rotation speed. To address this, we propose an integrated double-string groove bow wheel. Utility Model Content

[0005] The purpose of this invention is to provide an integrated double-string groove bow wheel to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated double-chord groove bow wheel, comprising a bow wheel body, a main chord groove being formed on the outer side of the bow wheel body, a limiting protrusion being provided in the main chord groove of the bow wheel body, the limiting protrusion dividing the main chord groove into two unit chord grooves, the width of the bow wheel body at the main chord groove being no more than 15mm, and the center distance between the two unit chord grooves being no more than 8mm.

[0007] Preferably, the cross-sectional shape of the unit groove is semi-circular.

[0008] Preferably, the bow wheel body and the limiting protrusion are an integral structure.

[0009] Compared with the prior art, the beneficial effects of this utility model are: dividing a main string groove into two unit string grooves can reduce the thickness and weight of the bow wheel, thereby increasing the rotational speed of the bow wheel during use; and compared with the prior art, the distance between the two unit string grooves in this application is shorter, so the impact on the bow string is smaller when the hub swings.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0018] Please see Figure 1-5In this embodiment of the present invention, an integrated double-string groove bow wheel includes a bow wheel body 1. A main string groove 2 is formed on the outer side of the bow wheel body 1. A limiting protrusion 3 is provided in the main string groove 2 of the bow wheel body 1. The bow wheel body 1 and the limiting protrusion 3 are an integral structure. The limiting protrusion 3 divides the main string groove 2 into two unit string grooves 4. The width of the bow wheel body 1 at the main string groove 2 is no greater than 15mm, and the center distance between the two unit string grooves 4 is no greater than 8mm. Dividing one main string groove 2 into two unit string grooves 4 can reduce the thickness and weight of the bow wheel, thereby increasing the rotational speed of the bow wheel during use. Compared with the prior art, the distance between the two unit string grooves 4 in this application is shorter, and the impact on the bow string is smaller when the hub swings. The cross-sectional shape of the unit string groove 4 is semi-circular.

[0019] The working principle of this utility model is as follows: dividing a main string groove 2 into two unit string grooves 4 can reduce the thickness and weight of the bow wheel, thereby increasing the rotational speed of the bow wheel during use; and compared with the prior art, the distance between the two unit string grooves 4 in this application is shorter, so the impact on the bow string is smaller when the hub swings.

[0020] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
