Abstract

The invention relates to a bow, in particular to a range-limited safety recurve bow. The range-limited safety recurve bow comprises a recurve bow frame, two pressing pulleys, two hinging wheels, two elastic telescopic pieces and a bowstring; the middle end of the recurve bow frame is connected with the two pressing pulleys in a sliding mode, and two ends of the recurve bow frame are rotationally connected with the hinging wheels respectively; one ends of the two elastic telescopic pieces are hinged to the two pressing pulleys respectively, and the other ends of the two elastic telescopic pieces are hinged to the eccentric positions of the two hinging wheels respectively; and two ends of the bowstring are connected to the eccentric positions of the two hinging wheels respectively. Accordingto the range-limited safety recurve bow, the pressing pulleys, the hinging wheels and the elastic telescopic pieces are arranged so that the range of the bow can be limited, and elastic potential energy in the recurve bow frame can be shared when the recurve bow shots without arrows, so that the recurve bow frame is prevented from being broken.

Description

technical field [0001] The invention relates to a bow, in particular to a limited-travel safety recurve bow. Background technique [0002] Bow is the oldest projectile weapon among projectile weapons. It is composed of elastic bow arm and flexible bow string. When the power accumulated in the process of drawing the bow is released in an instant, the arrow buckled on the bow string can be released. Shoot at distant targets. The range of the bow can reach 400 meters, and its power is greater than that of a pistol, so the bow is an extremely dangerous device. Nowadays, bows are mostly used in entertainment or competitions, but they have great destructive power and are more dangerous when used; moreover, when the bow is empty, the bow arm is easy to break and hurt people, so the traditional bow is safe when used. poor. Contents of the invention [0003] The object of the present invention is to provide a limited-range safe recurve bow, which is provided with a pressing pull...
