Abstract
The invention discloses a rigid case ejecting method for a short cartridge case firearm. The method is characterized in that in a rigid case ejecting mechanism, an inclined plane which forms a chamfer is arranged on the top of a step of a case ejecting support, so that the side of the bottom end face of a cartridge case is in contact with the inclined plane under drawing of a case draw hook during case ejection, and the side of the bottom end face of the cartridge case collides with the inclined plane under drawing of the case draw hook, moves along the inclined plane in certain distance and then is ejected out of a case ejecting window. By modifying the structure of the case ejecting support, the acting relation between the cartridge case and the case ejecting support is changed. By the method, the rotating condition of the cartridge case and the time when the cartridge case is separated from the case draw hook can be changed, and the collision condition of the cartridge case and the case ejecting window during case ejection can be obviously improved, so that case ejection of the short cartridge case is reliable, and the case ejecting route is stable; and the method is suitable for case ejection of the short cartridge case of which the gravity center is close to the bottom of a cartridge.
Description
Technical field
The present invention relates to a kind of automatic weapon ejection method, especially a kind of short shell case firearms rigidity ejection method.
Background technology
When the automatic weapon cartridge shooting, need to adopt extractor to carry out ejection, to guarantee the continuity of shooting.
Extractor mainly contains two kinds of rigidity extractor and elasticity extractors, and the rigidity extractor uses more in the pistol.Existing rigidity extractor; Its structure is as shown in Figure 1; Comprise casing, extractor 3, ejector 4 and shell throwing-out window 1; Said shell throwing-out window 1 is opened on the trajectory of casing, and said extractor 3 is positioned at a side of shell throwing-out window 1, and said ejector 4 is arranged on the trajectory inwall side relative with shell throwing-out window 1 and extractor 3; The inboard that said extractor 3 is positioned at an end of shell throwing-out window 1 has inside crook; This crook catches on shell case 2 near the cannelure of bottom one side and to the direction pulling away from shell throwing-out window when being used for ejection, have the step of the crook setting of corresponding extractor on the said ejector 4, and step is used for when ejection, withstanding shell case 2 bottom faces by the top of step shell case 2 is ejected from shell throwing-out window 1.Wherein, Reliable for guaranteeing ejection, shell case and ejector have the collision overlapping amount (being that thrum shell bottom face is pushed up the distance of position, place to the bottom edge position) about 1.5 ㎜～2mm, before shell case is thrown off extractor; All the time the top that is the ejector step contacts with shell case; Shell case is in rotation rearward after coming off on the extractor under the ejector effect, and behind its oral area side columnar portion and shell throwing-out window peripheral collision, direction of rotation changes and shell case is flown out to body of a gun front upper place.In this process, the distance at nest center and shell throwing-out window edge is a key factor that influences the ejection reliability at the bottom of the bullet, and to short shell cases such as 9 millimeters crust La Beilumu pistol cartridges, 9 millimeters pistol cartridge shell cases of 92 formulas, this distance receives structural limitations, is difficult to shorten.Like this, the center of gravity of feasible short shell case is an inner side at the shell throwing-out window edge, thus be not easy outside upset after the shell case collision, very big to the reliability effect of ejection when the gunlock movement velocity changes, the failure to eject or the fault that gets stuck often take place.
