Abstract

The utility model relates to a composite bow which is composed of a bow handle, a bow sheet, a connecting support of the bow handle and the bow sheet, a wheel and axle group, eccentric wheel groups, a bow string, a cable, a string divider, an arrow platform, a sighting device and a releasing device, wherein the bow handle is provided with a wind tunnel, the bow handle is connected with the bow sheet through the connecting support of the bow handle and the bow sheet, the bow sheet is connected with the eccentric wheel groups through the wheel and axle group, and the upper eccentric wheel group is connected with the lower eccentric wheel group by means of the bow string and the cable. The symmetrical force after a bow is pulled is greatly reduced through the function of lever force of eccentric string wheels in the eccentric wheel groups, and thus, the bow can be conveniently controlled; the pulling distance and the pulling force of the bow string can be adjusted and changed by various grades of string guiding positioning grooves of the string wheels, various grades of cable guiding positioning grooves of a cable wheel is used for adjusting the pulling force, and a pulling distance braking line at the straight line part of the cable wheel is used for controlling the pulling distance of the bow string; the cable is moderately separated from the bow string by the string divider, and thus, the arrow feathers are prevented from being scraped; the shooting direction of an arrow is adjusted by the arrow platform, three-point-one-line relation of two points of the bow and a target is realized by the sighting device, and the bow string is lured and hooked by the releasing device to reduce the contacted area of fingers and the bow string.

Description

Laminated bow

Technical field

The utility model relates to a kind of archery apparatus, specifically relates to a kind of laminated bow.

Background technology

At present, employed bow in China and the Olympic Games target day project mainly is made up of grip handle, arculae, bowstring, arrow platform, sight, damping balancer.Pulling the bow is to need the artificial consistent distance and the uniformity of geometrical relationship in length and breadth of drawing, and realizes penetrating the purpose of standard.Increase along with the distance of pulling the bow, pulling force increases accordingly, pull the bow when putting in place when also being the pulling force maximum, so the people is difficult to unanimity to the front and back straight line force control of bow, vertical, the horizontal geometrical relationship of bow after drawing back cannot say for sure that also card is consistent, especially colludes the string finger and keep away unavoidable influence to the bowstring active force especially in the dispenser process.

Summary of the invention

The purpose of this utility model provides a kind of under same pulling force, can guarantee that the pulling force that draws one of distance to make peace after drawing back reduces significantly; Can also adjust change bow draw distance and pulling force; Can reduce artificial factor to greatest extent again, be convenient to aim at, dispenser and raising penetrate the laminated bow of accurate accuracy.

For achieving the above object, the utility model is taked following design: a kind of laminated bow, it is characterized in that: it connects holder, axle set, eccentric group, bowstring, cable, string separating device, arrow platform, sight by grip handle, arculae, sheet and removes puts device and forms, grip handle is provided with wind-tunnel, grip handle, arculae connect by sheet is connected holder, arculae is connected with eccentric group by axle set, and eccentric group utilizes bowstring and cable to link together up and down.

The utility model has the advantages that: the utility model laminated bow can alleviate the front and back symmetry control of drawing back cantle, has guaranteed to draw to draw the uniformity of distance effectively; The same selection location that draws a bow by the string cable, what can change bow draws distance and pulling force, and aiming mode is accurate, and energy discharges fast, and ejection force is strong, penetrates accurate accuracy height.It is wide to be suitable for motion colony scope, is easy to popularize.
