A pulley for compound bow

Abstract

A pulley used in compound bows. The pulleys are respectively arranged at the two ends of the bow arm and connected with the main string and the auxiliary string, so that the bow can be drawn more effortlessly. It includes a shaft hole, a main string, an auxiliary string and a metal rod. , the shaft hole is pivotally connected with the bow arm, the main string is connected with the auxiliary string, the main string has a main string post, the main string post has a first hole and is provided with a metal rod, the auxiliary string has an auxiliary string post, and the auxiliary string The post has a second hole and is equipped with a metal rod. The main string post and the auxiliary string post of the compound bow pulley will bear considerable force when the bow is drawn. The metal rod is harder than the main string post and the auxiliary string post. Therefore, the main string post The string post and the auxiliary string post can withstand greater force than when no metal rod is installed. It can be applied to advanced compound bows with a large pulling force, and the production cost is low. It is also quite suitable for entry-level compound bows.

Description

technical field [0001] The invention relates to a pulley applied to a compound bow. The pulley is arranged at the two ends of the bow arm of the compound bow and is connected with the main string and the auxiliary string, which can save labor when drawing the bow. Background technique [0002] The bow is a hunting tool. Until now, the demand for hunting has declined. In addition to being used for hunting, the bow has also become a very popular competitive item. In order to meet the needs of various users, major manufacturers have successively developed better bow. [0003] In addition to the traditional recurve bow, the current bows on the market also have a compound bow for users to choose from. The structure of the compound bow is different from the recurve bow in that it uses an eccentric pulley. The two ends of the bowstring are fixed on the pulley, and the bowstring of appropriate length is installed through the pulley groove, so as to use the lever principle of the pu...
