Description

TECHNICAL FIELD

[0001] The utility model relates to sports equipment technical field especially a bow body levelness adjusting structure and contain the compound bow of this structure. BACKGROUND

[0002] Compound bow is a bow that is different from single bow, and its development history is quite long. Modern compound bow, also known as pulley bow, is a special equipment for sports competition archery, which is composed of a complex mechanical system, and the kinetic energy of the bow is converted into potential energy by means of pulley system, so that the compound bow has high elasticity and stability and long shooting range.

[0003] Modern compound bow is mainly composed of bow body, string and pulley system. The manufacturing materials include carbon fiber, glass fiber and aluminum alloy, and the combination of these materials gives the compound bow higher strength and better elasticity.

[0004] It is extremely critical to ensure the levelness of compound bow during shooting, mainly based on the following reasons. From the flight trajectory of the arrow, if the compound bow is not kept horizontal at the moment of shooting, the contact angle between the arrow feather and the air will deviate, resulting in unbalanced force of the air on the arrow feather, and then the arrow deviates from the original straight flight trajectory, producing side deviation, which greatly affects the shooting accuracy. For example, in long-distance shooting, slight angle deviation may cause the arrow to deviate greatly from the target.

[0005] In terms of mechanical principles, holding the bow horizontally can ensure that the force applied by the bow body to the arrow is along the axis of the arrow, so that the arrow obtains the most stable and efficient initial kinetic energy. If the bow body is inclined, the direction of the force will be decomposed, and part of the force will produce lateral component, which not only wastes energy, but also interferes with the flight stability of the arrow, making it difficult to hit the expected position.

[0006] Therefore, it is particularly important to design a bow body levelness adjusting structure. CONTENT OF THE UTILITY MODEL
