As Fig. 1～shown in Figure 23, a kind of pull-fork spring-pressing trigger system for gun is characterized in that this system comprises: gunlock body 1, sleeve 2, firing pin 3, firing pin return spring 4, hammer 5, hammer spring 6, duck-beak type spring 7, sleeve cap 8, shell-like shift fork 9, shell-like shift fork return spring 10, trigger 11, trigger return spring 12, trigger alignment pin 13, trigger locating pin spring 14.Gunlock body 1 concentric locking collar is located at the front end of sleeve 2 as described in (as Fig. 1～shown in Figure 5), sleeve 2 has a profound groove 15 near the lower end of gunlock body 1 parts is coaxial, be provided with firing pin return spring 4 and sheathed firing pin 3 in firing pin return spring 4 in corresponding gunlock body 1 sleeve 2 front ends, be provided with hammer 5 and hammer spring 6 thereafter, be embedded duck-beak type spring 7 in the fluting 16 of hammer 5 downsides, the rear end branch sleeve cap 8 (as Fig. 9, shown in Figure 10) and the enclosed shape of sleeve 2 are integral.Sleeve 2 outsides are positioned at gunlock body 1 rear end sheathed shell-like shift fork return spring 10, and coaxial line is provided with shell-like shift fork 9 thereafter, in the shell-like shift fork 9 center trepannings lower end establish one with duck-beak type spring 7 fan shape baffle 17 that the part front end cooperates of upspringing; Be that shell-like shift fork 9 axial rearward end inner undersides are provided with fan shape baffle 17, the part front end of upspringing of duck-beak type spring 7 touches mutually with this fan shape baffle 17.Lower end, shell-like shift fork 9 outside is provided with the trigger dowel hole 18 perpendicular to shell-like shift fork 9 axis, trigger dowel hole 18 wall lower ends have a groove 22 perpendicular to trigger dowel hole 18 axis, are provided with trigger locating pin spring 14 and trigger alignment pin 13 in its trigger dowel hole 18; Trigger 11 is
Shape, the parallel correspondence in middle part is provided with the twice beam, the front end face of beam vertically downward, the rear end face of beam vertically upward, have via hole 19 on the rear end face of beam and be placed on sleeve 2 outsides, trigger return spring 12 places between trigger 11 rear end faces and the sleeve cap 8, and the lateral separation correspondence respectively is provided with two dovetail grooves 20 on the twice beam of trigger 11, and two wing structures 23 of trigger dowel hole 18 interior trigger alignment pins 13 cooperate in relative positioned alternate in service with the dovetail groove 20 that trigger 11 is provided with on the shell-like shift fork 9.
Described sleeve 2 connects as one with gunlock body 1 tight fit.
Described trigger alignment pin 13 lower ends that cooperate with groove 22 location of dovetail groove 20 and trigger dowel hole 18 walls are two wing structures of parallel symmetry.
More particularly, sleeve 2 downsides that firing pin 3 and hammer 5 be housed at the same time have one section profound groove 15 (as Fig. 6, Fig. 7, shown in Figure 8), one firing pin return spring 4 is housed between firing pin 3 and the sleeve 2, establish a fluting 16 (as Figure 11 at hammer 5 downsides, Figure 12, shown in Figure 13), embed 7 (as shown in figure 17) of duck-beak type spring in the fluting 16, the connection termination of duck-beak type spring 7 embeds in the through hole at hammer 5 flutings 16 rear portions, the hammer spring 6 that hammer 5 rear portions are provided with is sheathed on hammer 5 rear ends, the rear end of hammer spring 6 is hindered by sleeve cap 8, have the front end of profound groove 15 parts outside sleeve 2, the shell-like shift fork 9 that the profound groove 15 corresponding fan shape baffles 17 on that be provided with the part segment length in it and the sleeve 2 are housed is (as Figure 14, Figure 15, shown in Figure 16).In the use, press and be connected the trigger alignment pin 13 in the trigger dowel hole 18 on the shell-like shift fork 9, make trigger alignment pin 13 two wing structures 23 (as Figure 22, shown in Figure 23) disengaging trigger 11 prelocalization dovetail grooves 20, be that latching slot is (as Figure 19, Figure 20, shown in Figure 21), enter in the groove 22 of trigger dowel hole 18 walls on the shell-like shift fork 9 (as Figure 14, Figure 15, shown in Figure 16), trigger 11 breaks away from the restriction of trigger alignment pin 13, under 12 effects of trigger return spring, trigger 11 is ejected to the operating position, two wing structures 23 of trigger alignment pin 13 are under the effect of trigger locating pin spring 14, from shell-like shift fork 9, eject the groove 22 of trigger dowel hole 18 walls voluntarily, locate dovetail groove 20 and enter trigger 11 backs that are in ejection process, be that work nest is (as Figure 19, Figure 20, shown in Figure 21), trigger 11 is re-positioned at (as shown in Figure 2) on the shell-like shift fork 9, cocking 11, trigger 11 is by trigger alignment pin 13, driving shell-like shift fork 9 is moving after by forward direction on profound groove 15 positions of sleeve 2, the fan shape baffle 17 of shell-like shift fork 9 promotes duck-beak type spring 7 (as Figure 17, shown in Figure 180), drive hammer 5 motion backward simultaneously, and compression hammer spring 6, duck-beak type spring 7 is in the process of motion backward, its part of upspringing is stopped by profound groove 15 back edges of sleeve 2 and is subjected to downward extruding, when shell-like shift fork 9 moves to certain position, fan shape baffle 17 position contacting of upspring the part front end and the shell-like shift fork 9 of duck-beak type spring 7 move down until disengaging (as shown in Figure 3) thereupon, when contact breaks away from, the power pop-off that duck-beak type spring 7 is pushed rearward, and forwards the obstruction to motion also disappears simultaneously, is promoted by duck-beak type spring 7 and hammer 5 that WKG working moves backward forwards also disappears (as shown in Figure 3) simultaneously to the obstruction of motion; Like this, hammer 5 is under the promotion of compressed hammer spring 6, moment is driving duck-beak type spring 7 and is travelling forward, hammer 5 impacts firing pin 3 in this motion later stage, firing pin 3 percussion ammunitions (as shown in Figure 4), thereby finish firing action, firing pin 3 is got back to the position before the percussion under the effect of firing pin return spring 4, shell-like shift fork 9 is under the effect of trigger return spring 14, travel forward with trigger 11, crossing the upspringing during part of hammer 5 and duck-beak type spring 7, its inertia drives its compression shell-like shift fork return spring 10, after it travels forward and finishes (as shown in Figure 5), the part front end of upspringing of duck-beak type spring 7 is higher than fan shape baffle 17 lower ends of shell-like shift fork 9 again, under the effect of shell-like shift fork return spring 10, shell-like shift fork 9 moves backward and returns to initial contact condition (as shown in Figure 2) with the duck-beak type spring 7 part front end of upspringing again until its fan shape baffle 17.Press trigger alignment pin 13 once more, make two wing structures 23 of trigger alignment pin 13 break away from the work nest that trigger is located one of dovetail groove 20, enter in the groove 22 in trigger dowel hole 18 walls on the shell-like shift fork 9, trigger 11 breaks away from the restriction of trigger alignment pin 13, while cocking 11, two wing structures 23 of trigger alignment pin 13 are under the effect of trigger locating pin spring 14, from the latching slot that is advanced into trigger 11 another location dovetail grooves 20 in advancing, trigger 11 is re-positioned on the shell-like shift fork 9, and trigger 11 also is in locking states (as shown in Figure 1) again.
Above-mentioned with reference to embodiment to the detailed description that this pull-fork spring-pressing trigger system for gun carries out, be illustrative rather than determinate, therefore, should belong within protection scope of the present invention in the variation and the modification that do not break away under the general plotting of the present invention.
