Description
Technical field
the utility model relates to 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
the purpose of this utility model be to provide a kind of utilize balanced pulling force and improve the mode of square of pulling the bow solve the arm extending type laminated bow that arm not easily expands and be not suitable for the problems such as pulling force.
the arm extending type laminated bow that the utility model proposes comprises the arc bent body that two ends are separately installed with ear seat and the drag-line be connected with two ear seats, and being arranged on an arrow shaft part of arc bent body central region, described arc bent body two ends are separately installed with the runner assembly limited by turning cylinder and the bowstring being connected to two runner assembly ends.
described arc bent body central region is provided with reinforcement plate, and is provided with grip handle in the side of reinforcement plate.Described arrow shaft part comprises front the arrow shaft and rear arrow shaft that are arranged on reinforcement plate both sides, and a rear arrow shaft is made up of L shape rod member, in L shape rod member, arrange limited arrow plate.
before described, the free end of an arrow shaft is provided with a vertical member, and the side at the two ends up and down of this vertical member is separately installed with front sight unit and front arrow platform.Described reinforcement plate is provided with rear arrow platform towards the direction of front arrow platform.
described bowstring is provided with rear sight unit.
described runner assembly comprises and is separately positioned on dwang on turning cylinder and convex plate, and the connector for dwang and convex plate being fixed together.
the arm extending type laminated bow that the utility model proposes adopts the runner assembly be connected with bowstring, this runner assembly is made up of dwang and convex plate, because dwang is longer, in the process of not pulling the bow, bowstring can extend to the front portion of arc bent body, and the distance of the string that can make to pull the bow when shooting an arrow extends, the arm of people can be made to launch completely on the one hand, being very suitable for archery person to pull the bow, on the other hand because improving toxophilitic balanced pulling force, archery distance can being increased; In addition, arrow platform and rear arrow platform before an arrow shaft part and reinforcement plate are respectively arranged with, and be also provided with front sight unit and rear sight unit, be very beneficial for aiming at archery, and the degree of accuracy of archery can be improved.
