Embodiment Construction

[0012] Such as figure 1 Shown, structure of the present invention is made up of vertical crossbow bow body 2, combination roller 3, string 4, extension spring connecting rope 12, extension spring 10, spring protective tube 11, retaining string piece 13. Wherein, two string blocking blocks 13 are distributed side by side on the arrow path of the crossbow body, the combined roller 3 is fixed on the front end of the crossbow body 2 by the bolt pin assembly 16, and the right end of the extension spring 10 used as energy storage is fixed on the spring casing 11, and the other end It is connected with the connecting rope 12, wherein the spring casing 11 and the crossbow body 2 are fixed by screws and do not move relative to it.

[0013] Such as figure 2 , 3 As shown, the combined roller 3 is composed of three parts, namely two large-diameter rollers and a small-diameter roller in the middle, and the three rollers rotate at the same angular velocity around the axis. The connectin...

Abstract

The invention provides a novel energy storing device for a crossbow. A combination roller and a tension spring are fixedly arranged in a vertical crossbow body by bolt pins respectively; the combination roller consists of two rollers with different diameters; two large rollers and a small roller in the middle keep rotating synchronously; a bowstring for pushing an arrow is divided into two strands which are wound on two large-diameter rollers of the combination roller respectively; and a bowstring connected with the tension spring is wound on a small-diameter roller of a combination pulley. Due to the adoption of the vertical crossbow body, the crossbow has compact and simple structure and good compactness; and the combination roller and the tension spring are arranged in the crossbow, so that the initial arrow ejecting speed of the crossbow is increased, and labor-saving operation is realized.

Description

[0001] Field: [0002] The invention relates to a new crossbow bow body, especially an energy storage device providing power and a structural frame for the crossbow. Background technique: [0003] At present, the ancient weapons such as bows and crossbows have not only become popular entertainment, sports and hunting equipment, but also as special equipment for special police, and have a wide range of application prospects. There have been many innovations in the specific structure and shape of modern crossbows, such as patents 93105057.X, 99237136.8, 02245366.0, 200920091473.1, etc., but they are generally composed of three parts: crossbow, crossbow arm and crossbow machine: the crossbow is mounted on the front end of the crossbow arm , The crossbow machine is installed at the rear of the crossbow arm. The crossbow arms are used to support the bow, brace the strings, and be supported by the user; the crossbow machine is used to buckle the strings and launch them. Since the ...
