Abstract

The utility model relates to the technique of a bow, which comprises a bow body (1), pulleys arranged at the both ends of the bow body (1), and bow strings (3) arranged on the pulleys (2). When the bow string of the bow is pulled, only small force is used, but the force of shooting an arrow is close to the three times of a string pulling force, and accordingly, the utility model causes arrow speed to be improved, and a shooting distance is farther.

Description

Bow and arrow

The utility model belongs to the technical field of bow.

Our used bow and arrow all is a monochord now, the two ends of string respectively bolt on the two ends of bow body.It is far away that the arrow that wants to make bow to penetrate is penetrated, and then must add the coefficient of elasticity of longbow body, thereby make the elastic force that produces after the cast big, make far away that arrow penetrates, but for the big bow of coefficient of elasticity, spur string and then must use very large power, power is too big then the people haul very painstaking.

The purpose of this utility model provides a kind of firmly little and bow and arrow far away that arrow is penetrated when drawing string.

This bow and arrow comprises the bow body, at the two ends of bow body pulley is housed respectively, and bowstring is housed on pulley.

Because pulley is equipped with at the two ends at the bow body, bowstring is wrapped on the pulley, after the pulling bowstring deforms the bow body, decontrol bowstring, the pulley that then bends the body two ends is pop into position under the effect of bow body, and the pulley of this moment is equivalent to a movable pulley, and the bowstring of band arrow has become then that movable pulley drives holds the thing rope, thereby the power exported of bowstring of band arrow is multiplied, thus arrow penetrate far away.

Accompanying drawing shows embodiment of the present utility model, wherein,

Figure 1 shows that the front view of the bow and arrow of embodiment 1;

Figure 2 shows that the front view of the bow and arrow of embodiment 2.

Embodiment 1, bow and arrow as shown in Figure 1 comprises bow body 1, is contained in two pulleys 2 at bow body 1 two ends respectively by axle, be contained in the bowstring 3 on two pulleys 2, and pulley 2 bolts that the two ends of bowstring 3 are walked around respectively separately bend on the ring of body at the other end relative with the pulley of walking around.

Embodiment 2, and bow and arrow as shown in Figure 2 comprises bow body 1, are contained in two pulleys 2 at bow body 1 two ends respectively by axle, are contained in the bowstring 3 on two pulleys 2, and the two ends of bowstring 3 are walked around separately pulley 2 bolts respectively on another pulley spindle relative with the pulley of walking around.

Claims

1, a kind of bow and arrow comprises bow body (1), it is characterized in that at the two ends of bow body (1) pulley (2) being housed respectively, and bowstring (3) is housed on pulley (2).

2, bow and arrow according to claim 1, the two ends that it is characterized in that bowstring (3) are walked around separately pulley (2) bolt respectively on the ring of the other end bow body relative with the pulley of walking around.

3, bow and arrow according to claim 1, the two ends that it is characterized in that bowstring (3) are walked around separately pulley (2) bolt respectively on another pulley spindle relative with the pulley of walking around.
