Description
Technical field
The utility model belongs to sports apparatus and hunting instrument field.Held first bow and crossbow World Championships in Austria in 1979.Bow and crossbow was put into Olympic Games demonstration event in 1988!
Technical background:
China is acknowledged as the country of invention bow and crossbow the earliest.The bronze trigger mechanism of a crossbow on the nineteen fifty-two Chu Mu of the Changsha Warring states goes out is very exquisite, and the invention of crossbow can be traced back to Warring states mid-terms at least, just has so far more than 2300.Existing crossbow all is that the anterior pin stirrup of crossbow that tramps with one's feet draws crossbow string (3) to go up crossbow string (3) at both hands mostly.Get up very difficultly 200920099538.7 company's crossbow of application number, long lever design too short pulling, the high-tensile strength crossbow sheet (2) of modern production draws motionless at all.The lever conduit causes the short too short range and the power that will influence crossbow of strike stroke that causes crossbow string (3) of pulling crossbow string (3) distance at the front end of trigger, also can impact accuracy rate.The utility model increases handle cavity (13 (1)) more extend long lever (12) to increase leverage and spurs more laborsaving.Trigger (14) makes it walk around lever conduit (4) increase pulling crossbow string (3) through improvement and hits longer power and the accuracy rate that increases crossbow of stroke apart from making crossbow string (3).
Summary of the invention
The purpose of this utility model is to allow crossbow draw crossbow string (3) lighter, and lengthening draws crossbow string (3) distance to make crossbow string (3) hit longer power and the accuracy rate that increases crossbow of stroke.
Embodiment of the present utility model to achieve these goals is, the pull string crossbow device mainly includes lever conduit (4), draws string guide rail (5), press arrow sheet (6), lock string hook (7) draws string hook (8), draws the string hook to bump (9), draw string hook seat (10), long lever (12), short lever (16) is characterized in that; Be to fix lever conduit (4) below crossbow string (3) the crossbow string guide rail (1) above the crossbow string guide rail (1), lever conduit (4) front end connects short lever (16) in the middle of connecting long lever (12) long lever (12), short lever (16) other end passes conduit carriage release lever (19) front end that lever guide rail (18) connects lever conduit (4) the inside, conduit carriage release lever (19) rear end is being fixed and is being drawn string hook seat (10), draw string hook seat (10) other end to pass and draw string guide rail (5) to link to each other with drawing string hook (8), drawing directly over the string hook (8) is to draw the string hook to bump (9), drawing the string hook to bump (9) middle is a tube, and tube presses when drawing string hook (8) can rotate the power of reducing friction.
The utility model has the advantages that, the bent intermediate of trigger (14) is walked around lever conduit (4) lever conduit (4) can add long lever conduit (4) as required, increase and draw crossbow string (3) pull distance, increase the strike stroke of crossbow string (3), crossbow string (3) speed increases the secondary Firing Velocity in the quickening.

Be described further by reference to the accompanying drawings;
Shown in the figure one; Be to be fixed wtih lever conduit (4) below crossbow string (3) the crossbow string guide rail (1) above the crossbow string guide rail (1), the dead astern of crossbow string (3) is lock string hook (7).
Shown in the figure two; Draw string hook (8) drawing the string hook to bump below (9), drawing string hook (8) side is to draw string hook seat (10), and drawing the string hook is a tube in the middle of bumping (9), and tube presses when drawing string hook (8) can rotate the power of reducing friction.
Shown in figure three figure four figure five; Lever conduit (4) front end connects short lever (16) in the middle of connecting long lever (12) long lever (12), short lever (16) other end passes conduit carriage release lever (19) front end that lever guide rail (18) connects lever conduit (4) the inside, pipe carriage release lever (19) rear end is fixed wtih draws string hook seat (10), draws string hook seat (10) other end to pass and draws string guide rail (5) to link to each other with drawing string hook (8).
Shown in figure six figure seven; Jug groove (13 (1)) handle cavity (13 (1)) can be buckled on the guard timber (17) in the middle of the handle (13), and it is more laborsaving that the overlapping length that reduces space and increase long lever (12) of handle cavity (13 (1)) and guard timber (17) increases the leverage pulling.
