Description
Technical field
The utility model relates to bow and arrow field, particularly a kind of arm extending type compound bow and arrow.
Background technology
Tradition bow and arrow is a kind of direct-pulling type bow and arrow, and it is primarily of grip handle, arculae and bowstring composition.This kind of bow and arrow can cause " successively decreasing layer by layer " effect when pulling the bow, what namely bow drew more opens, and required power of pulling the bow can increase clearly, will cause less stable like this, and is unfavorable for aiming at; In addition, the bow of this type, elasticity is poor, and range is comparatively near, can not meet the needs of long distance range; In addition, this bow and arrow also comprises the side reflex bow different from common longbow, the end of reflex bow bow arm is bent outwardly, although reflex bow can store more energy, makes the arrow of injection have higher kinetic energy, the bow arm of contrary flexure simultaneously can bear larger pulling force, but contrary flexure draw weight is less than half arm exhibition of human body, and in the process of pulling the bow, after bow is winded up, become unstable, cause its pulling force progressively to strengthen, this unbalanced pulling force can make the effective pull of human body be not fully utilized.Bow and arrow of the prior art also comprises laminated bow, and this laminated bow is by pulley and the latch plate utilizing composite to make, and parts such as support handle and the string of a musical instrument etc. are combined into.Laminated bow is the principle utilizing mechanical force moment, is converted into potential energy by potential energy, when being pulled through cam summit with bowstring to pulling force relative equilibrium used when completely bending within the scope of this, so laminated bow is more laborsaving when pulling the bow and aim at; Although the pulling force relative equilibrium that laminated bow adopts, but its pulling force is less than the active force of human body substantially, and the length making human body arm open up also does not expand, and in the process of pulling the bow, if the arm of human body does not launch internal force to be discharged completely completely, so, this laminated bow does not meet human body pulling force, in addition, because laminated bow is the bow that structure is very complicated, parts are more, and cost of manufacture is higher.In order to solve the problem, name disclosed in No. 2351739, Chinese patent is called that the patent of " the crossbow body of built-in pulley extension spring " provides a solution.This crossbow body is by T-shaped bow body, bowstring and extension spring are formed, extension spring one end is fixed on the vertically interior bottom of T-shaped bow body, steel wire rope is equipped with on its top, and the fixed pulley in T-shaped bow body upper crosstalk tube is contained on movable pulley, there is fixed pulley at transverse tube two ends, and bowstring is after fixed pulley and movable pulley, and two ends are separately fixed at transverse tube end.Although the extension spring in this crossbow body can make elastic potential energy be converted into kinetic energy, and fixed pulley supporting steel-cable can ensure the stable of bowstring and spring steel wire rope direction, the angle that movable pulley then changes bowstring steel wire rope in good time ensures that it is static and the growth of state of winding up, but to be the mode utilizing bowstring to reset penetrate arrow for it, and the amount of force that bowstring resets is relevant with the elasticity of bowstring, if bowstring has larger elasticity, only could by far away for arrow injection when pulling force is larger, under contrary condition, arrow is penetrated nearer, so, this crossbow body is also not suitable for proprietary pulling force.
Summary of the invention
