Description

Lian Nu

Technical field

The utility model discloses a kind of even crossbows.

Background technique

Crossbow is also referred to as " nest bow ", " cross bow ".It is a kind of weapon for shooting an arrow.Crossbow is a kind of bow equipped with arm, main It to be made of the part such as crossbow arm, crossbow, bowstring and trigger mechanism of a crossbow, crossbow lies across crossbow arm front end；Crossbow arm is equipped with arrow slot, and trigger mechanism of a crossbow setting exists Arrow slot tail end, bowstring are located at the top of crossbow arm, and both ends bolt is hung on two panels crossbow, and body with cord is hung on the hook in the trigger mechanism of a crossbow, hair When penetrating, arrow arrow is placed in arrow slot, hook is pulled open, drives bowstring to form the kinetic energy rapidly sprung back using the crossbow of opening, by arrow High speed projects, and records Zhu Gelian crossbow in history, can once emit ten arrow arrows, since Zhu Gelian crossbow is in lost shape State, many people think duplication Zhu Gelian crossbow, but existing imitated Zhu Gelian crossbow, distinguish the more of the arrow slot number being only that on crossbow arm Few, remaining structure is roughly the same with the structure of common crossbow, due to being located at the inclined angle of bowstring of hook two sides after extension string, is hitting When hair, the arrow arrow of two sides arrow slot is first fired in more arrow slots, and the arrow arrow positioned at intermediate arrow slot is by rear percussion, the during which kinetic energy of bowstring Decayed, the dispersion radii for causing arrow to be sweared is big, and accuracy at target is low.It is existing to connect crossbow in order to guarantee the shooting initial velocity of arrow arrow, usually It is used to strike more arrow arrows using the biggish bowstring of poundage, winds up more difficult, and arrow arrow needs to be arranged in arrow slot by root, Firing interval is very long, and the speed of repeated firing is very slow.

Summary of the invention
