The specific embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is described further.
Shown in Fig. 1 a, Fig. 1 b, a kind of open and close latch mechanism mainly is made up of gun barrel 1, connecting pin 2, switching latch fitting 3, backstay 4, backstay axle 5, jumper spring 6, tenon spring base 7, casing 8, locking tenon 9, locking tenon spring 10, the trigger 11 of unblanking, trigger 12.Open and close latch fitting 3 by connecting pin 2 and the gun barrel 1 composition barrel assembly that is assembled together.Backstay 4 is assembled together by backstay axle 5 and locking tenon 9, backstay 4 is a matched in clearance with backstay axle 5, backstay axle 5 is an interference fit with locking tenon 9, the all fluted jumper spring 6 that holds on backstay 4 and locking tenon 9, under the effect of jumper spring 6, backstay 4 is around 5 rotations of backstay axle, one end of backstay 4 is exceeded the last plane of locking tenon 9 by jack-up, on locking tenon 9, there is simultaneously a pane structure can limit the anglec of rotation of backstay 4, prevents backstay 4 rotations excessively.Backstay 4, jumper spring 6, backstay axle 5 and locking tenon 9 are formed locking tenon parts, be contained on the casing 8 and in the T-slot on the casing 8 and move, below casing 8T shape groove, have one with the identical groove of tenon spring base 7 shapes, be used for holding tenon spring base 7 and locking tenon spring 10, tenon spring base 7 is T shape bars, is used for guaranteeing that locking tenon spring 10 can off-axis in compression process; Locking tenon spring 10 is enclosed within on the tenon spring base 7, and the circular hole that the small end of tenon spring base 7 passes locking tenon 9 belows heads on locking tenon 9 by locking tenon spring 10, and the big end of tenon spring base 7 withstands one of casing 8 groove.Unblank square opening and locking tenon parts that trigger 11 passes casing 8 are assembled together.Trigger 12 is contained on the casing 8.
Shown in Fig. 1 a, Fig. 1 b, at the complete atresia state, 10 pairs of locking tenons 9 of locking tenon spring apply active force, make its latch surfaces fasten the latch surfaces that opens and closes latch fitting 3, are assembled together by connecting pin 2 and gun barrel 1 and open and close latch fitting 3.Backstay 4 is opened and closed latch fitting 3 and pushes down in the groove that is limited to locking tenon 9 and can not rotate.When unblanking, pull the trigger 11 of unblanking backward, drive locking tenon 9 motion backward, the latch surfaces of locking tenon 9 breaks away from the latch surfaces that opens and closes latch fitting 3.Shown in Fig. 2 a, Fig. 2 b, this moment, gun barrel 1 was rotated in place under the effect of spring power unblanking, and the switching latch fitting 3 that is assembled together with gun barrel also raises, so the backstay of being pushed down 4 rotates around backstay axle 5 under the effect of jumper spring 6, backstay 4 one ends lift, and the other end is stuck in the groove of casing 8.Shown in Fig. 3 a, Fig. 3 b, locking this moment tenon 9 is positioned in this position.So far, unblank fully.At this moment, the L shaped protrusion piece of locking tenon 9 is pushed down trigger 12, and trigger 12 can not rotate, thereby realizes insurance function.
Shoot finish after, gun barrel 1 revolution is put in place, the switching latch fitting 3 front end plane contact on the barrel assembly are to the backstay 4 that protrudes plane on the locking tenon 9, and backstay 4 is pressed down.Around 5 rotations of backstay axle, the other end of backstay 4 no longer is stuck in the locating slot of casing 8 backstay 4 under the effect of jumper spring 6, does not have the locking tenon parts of location to travel forward under the effect of locking tenon spring 10, and the trigger 11 of unblanking travels forward simultaneously.Latch surfaces on the locking tenon 9 fastens with the latch surfaces that opens and closes on the latch fitting 3, finishes block action, shown in Fig. 1 a, Fig. 1 b.The L shaped protrusion piece of locking tenon 9 front ends is no longer pushed down trigger 12, and at this moment cocking 12 can be realized percussion.
Before the gun barrel locking, utilize locking tenon 9 control triggers, can't cocking when locking is not in place.The ability cocking is realized percussion, safety and reliability after the complete atresia.
The utility model is in order to solve the loaded down with trivial details problem of traditional baton gun unlocking action, designed the trigger of unblanking, the trigger of unblanking is positioned at the rear of trigger, only need the finger of mobile cocking backward during operation, pull the trigger of unblanking then and just can finish a series of unlocking action, the other parts of armed hand need not to move.In the locking process, avoided rigid collision.
