Description

Connect crossbow

Technical field;

The utility model belongs to the sports apparatus 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 bow invention had 1.5---2 10000 years apart from modern, invented agricultural than the mankind and wanted Zao.The bronze trigger mechanism of a crossbow that the nineteen fifty-two Chu Mu of the Changsha Warring states is unearthed 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.The shortcoming of tradition bow and crossbow is that the slow arrow of manually going up of the speed of winding up is shot more loaded down with trivial details again.

Summary of the invention;

The purpose of this utility model is to allow crossbow accomplish running fire.Accomplish that running fire must have and draw string automatically and automatically for the arrow device.

1 by lever handle (11), preceding lever dolly (9), back lever dolly (20), draw string hook moving leader (22), draw string hook Connection Block (13) to draw string hook (7) lever conduit (21), draw string hook Connection Block moving rail (10), crossbow string (16), lock string hook (6) draws the string hook to bump (8), and the lever of composition draws string.

2 lead the automatic confession arrow that arrow pipe (4) is formed by drawing string hook (7) top arrow plate depression bar (5) arrow folder fixator (15) arrow folder (17) top arrow plate (3) crossbow bolt (19) to push away arrow plate (18) crossbow bolt inlet (14).

3 the utility model main features are; Front and back pull lever pull handles (11) once just can be finished and draw string to supply arrow automatically automatically.Draw string fast, the lever principle that preceding lever dolly (9) back lever dolly (20) forms could drive draws string hook moving leader (22) to finish to draw string automatically.The jagged top arrow plate (3) that guarantees moved up and down in the middle of there were arrow folder fixator (15) and arrow folder (17) in the side, made top arrow plate (3) push up crossbow bolt (19).Top arrow plate (3) upper horizontal plane is higher than crossbow bolt inlet (14) lower limb to be rolled into crossbow bolt (19) smoothly to lead arrow pipe (4) and finishes automatic for arrow.Arrow folder (17) be independently carry standby very convenient.

Be described further by reference to the accompanying drawings.

(1) shown in the figure three; Arrow folder fixator (15) is lower than the upper water of crossbow string (16) arrow folder fixator (15) Plane and crossbow string guide rail (2) lower limb play crossbow string guide rail (2) effect in the same level position

(2) shown in the figure five; The lever principle ability that lever dolly (20) forms behind the front lever dolly (9) String hook moving leader (22) is drawn in drive. Lever pull handle (11) can lengthen to increase leverage.

(3) shown in the figure six; Drawing the string hook to bump (8) draws string hook rolling spring (not shown) to reduce resistance Make and draw string hook (7) and crossbow string (16) easily to break away from, draw string hook rolling spring (not shown) can use little iron Pipe and little bearing replace.

(4) shown in the figure seven, eight; Draw string hook (7) to press down and press top arrow plate depression bar (5) top arrow plate depression bar in addition It is because jagged in the middle of arrow folder fixator (15) and the arrow folder (17) that one end upwards lifts. Allow top arrow plate (3) Enough running spaces are arranged.

(5) shown in the figure ten; Preceding lever dolly (9) links to each other with lever conduit (21), preceding lever dolly (9) middle part links to each other with back lever dolly (20), back lever dolly (20) other end is connected drawing on the string hook moving leader (22) of lever conduit (21) lining, draw string hook (7) to link to each other, draw string hook Connection Block (13) other end to pass to draw string hook Connection Block moving guide rail (10) to be fixed on and draw on the string hook moving leader (22) with drawing string hook Connection Block (13).

(6) shown in the figure nine, 11; Jagged top arrow plate (3) can upward pushing up crossbow bolt (19) pushes away stressed the opening of arrow plate (18) smoothly in the middle of arrow folder fixator (15) the arrow folder (17).Top arrow plate (3) upper horizontal plane is higher than 0.5 millimeter of crossbow bolt inlet (14) lower limb, crossbow bolt is pushed arrow plate (18) and pushes from crossbow bolt inlet (14) and lead arrow pipe (4), push away arrow plate (18) center protrusion and crossbow bolt (19) is squeezed leading arrow pipe (4), can not move to drop out and lead arrow pipe (4) when the crossbow body aims at crossbow bolt (19) downwards.

(7) shown in the figure 14,15; Arrow folder (17) is independently to have spring (17 (1)) two that crossbow bolt catch (17 (2)) crossbow bolt U-shaped supporting plate (17 (3)) is arranged.Independent arrow folder (17) can guarantee to carry and increase standby arrow and press from both sides (17).

The specific embodiment;

Operating process of the present utility model is, (seeing figure five for details) when hand to inferoanterior pull lever pull handle (11), preceding lever dolly (9) back lever dolly (20) drives and draws string hook moving leader (22) to draw string hook Connection Block (13) to draw string hook (7) to travel forward along drawing string hook Connection Block moving guide rail (10) to drive, and crossbow string (16) is hooked at the drop-down string hook of spring action (7) in the position of arrival crossbow string (16).(seeing figure six for details) at this moment pulls back the preceding lever dolly of lever handle (11) (9) back lever dolly (20) drive and draws string hook moving leader (22) to draw string hook Connection Block (13) to draw string hook (7) to move backward along drawing string hook Connection Block moving guide rail (10) to drive.That draws string hook (7) pulling crossbow string (16) crossbow string (16) stretches tight under crossbow sheet (1) tension force effect is very tight, and lock string hook (6) erects locking crossbow string (16) when crossbow string (16) promotes lock string hook (6).Finish and draw string automatically.Continue to pull back lever pull handle (11).(seeing figure seven for details) draws string hook (7) to press top arrow plate depression bar (5) to pressing down drawing the string hook to bump under the effect of (8).(seeing figure eight for details) top arrow plate depression bar (5) other end has a reaction force that makes progress upwards to lift top arrow plate (3), and top arrow plate (3) also moves up and heads on crossbow bolt (19), and crossbow bolt (19) is pushing away arrow plate (18) jack-up.Top arrow plate (3) pushes up the position and pushes away arrow plate (18) and push from crossbow bolt inlet (14) at the following crossbow bolt of spring action (19) and lead arrow pipe (4).Lever pull handle (11) is the in-position also.Cocking (12) is realized emission.Repeatable operation realizes running fire.

More than for connecting the crossbow overall description.All equivalences of doing according to the utility model principle and feature change, all should be within the utility model scope.
