Description

Safety gun

The utility model relates to a kind of firearms that can launch special blank cartridge, it can not only simulate military shot, light, cigarette and percussion, ejection action, and the sound, light, gas and the impurity that produce do not have direct harm to human body, and its gun barrel can not emission band bullet bullet, the blank cartridge shell case can not load the live shell head, and emission back shell case is recycling.

At present, known military rifle structure by casing, gunlock, firing pin, draw that shell colludes, ejection very, trigger, sear, spring, gun barrel form.The blank cartridge that military rifle uses is made up of the fire in a stove before fuel is added, primer mixture, propellant powder, shell case, dress propellant powder in the shell case, dress primer mixture in the fire in a stove before fuel is added, and shell case head closure.During emission, gunlock is hung on the sear, behind the cocking, drivening rod, sear sinks, and spring is upheld, make the gunlock preshoot, firing pin impacts bullet primers, the primer mixture blast, and propellant powder ignites, the gas that produces is washed the shell case head of closure open, gases at high pressure and impurity fly out from muzzle by gun barrel, closely human body are being had direct harm, and the produced simultaneously huge sound also has infringement to people's ear.Shell case after the percussion is drawn shell to collude and is pulled out gun barrel, and is very withdrawed from outside the casing by ejection.In addition, after military blank cartridge is pulled the trigger, because closed head blows, so shell case can not utilize and the bullet of military rifle gun barrel energy emission band bullet again.

The purpose of this utility model provides a kind of Safety gun, it can not only launch special blank cartridge, simulate military shot, light, cigarette and percussion, ejection action, and the sound, light, gas and the impurity that produce do not have direct harm to human body, and its gun barrel can not emission band bullet bullet, the blank cartridge shell case can not tamp bullet, and emission back shell case is recycling.

The purpose of this utility model be achieved in that Safety gun by casing (1), gunlock (2), firing pin (3), very (6), trigger (11), sear (8), spring (5), gun barrel (14) are formed to draw shell to collude (4), ejection.On gun barrel (14) inwall choke piece (15) is arranged, there is the airway (16) of bore less than gun barrel (14) internal diameter at choke piece (15) center, gun barrel (14) in choke piece (15) position is gone up to high-low pressure control valve (17), and screw (18) and leakage port (19) are arranged on the high-low pressure control valve (17).Filter dirt pad (21) is arranged in the gun barrel (14), disturb gas plate (22), disturbing has blow vent (23) on the gas plate (22), on the inner edges also fluted (24).Blocking what disturb that gas pulls (22) is stopper (25), airway (26) is arranged on it, and have external screw thread to connect mutually with the internal thread of gun barrel (14).Stop in addition in the gun barrel (14) and pull (27) that stopping to pull has airway (28) on (27).The tube wall of gun barrel (14) has port (29).Blank cartridge (13) is made up of shell case (30), cartridge bag shell (33), the fire in a stove before fuel is added (36), primer mixture (39), propellant powder (38).Shell case (30) head opening has longitudinal rib (31), projection (32), internal thread (35) on the inwall.The extruding of cartridge bag shell (33) head is closed, and interior dress propellant powder (38) has external screw thread (34) on the shell, and on the shell wall of cartridge bag shell (33) bottom fluted (37), cartridge bag shell (33) bottom is the fire in a stove before fuel is added (36), dress primer mixture (39) in the fire in a stove before fuel is added (36).Load blank cartridge (13) before the emission earlier, snapping in cartridge bag shell (33) bottom groove (37) with instrument makes cartridge bag shell (33) go up external screw thread (34) screw-in shell case (30) internal thread (35), cartridge bag shell (33) is fixed on the shell case (30), projection (32) can stop cartridge bag shell (33) to move forward, longitudinal rib (31) protrudes to the center, so can stop the live shell head of packing into.During emission, blank cartridge (13) is put into gun barrel (14), gunlock (2) is hung on the sear (8), behind the cocking (11), drivening rod (10), sear (8) sinks, spring (5) is upheld, make gunlock (2) preshoot, firing pin (3) impacts blank cartridge (13) fire in a stove before fuel is added (36), primer mixture (39) blast, propellant powder (38) ignites, gas that produces and impurity will pushs closed cartridge bag shell (33) head and wash open, and rush at the mouth of pipe by gun barrel (14), when gas and impurity pass through on the choke piece (15) airway (16), choke piece (15) rises and stops live shell head or large granular impurity to hinder gas flow by reaching, increase the effect of ejection pressure, at this moment, if the gun barrel internal pressure is reduced, can regulate the screw (18) on the high-low pressure control valve (17), leakage port (19) is opened, and portion gas and impurity just flow out from leakage port (19), reach the decompression purpose of losing heart; If gun barrel (14) internal pressure is raise, adjustment screw (18) enters in the gun barrel (14) its top, hinders flowing of gas and impurity, reaches choked flow supercharging purpose.When gas and trash flow filtration dirt pad (21), filter dirt pad can stop and absorbed portion impurity.When gas and impurity are pulled (22) blow vent (23) by disturbing gas, disturb gas and pull the motion that (22) can be upset, hinder portion gas and impurity, weaken its impulsive force, and can increase ejection pressure, the groove on it (24) can further be upset the movement locus of gas and impurity.Block and disturb gas and pull the stopper of (22) (25), can stop and disturb gas and pull when (22) are impacted by gas and produce motion, and can hinder flowing of portion gas and impurity, increase ejection pressure, the airway on it (26) can make portion gas and impurity flow out.When gas and impurity arrived port (29), port (29) can change its flow direction, and it is flowed out from port (29), prevented that it from directly going out from muzzle, and made its step-down, noise reduction.When arriving, gas and impurity stops when pulling (27), stop that pulling (27) can hinder it and directly go out from muzzle, the portion gas and the impurity that keep off are back flowed out by port (29), and can increase ejection pressure, stop that the airway of pulling on (27) (28) can make portion gas and impurity flow out, and has step-down, noise reduction effect.Because gas and impurity are subjected to choke piece (15), screw (18), filter dirt pad (21), disturb gas plate (22), stopper (25) in gun barrel (14), the obstruction of barrier plate (27), make that shock wave is weakened, thereby also just reduced impulsive force, thereby reduced noise.Blank cartridge (13) is by after pull the trigger, owing to be subjected to pressure backward, moves backward so drive gunlock (2), and owing to draw shell to collude the interaction that (6) are endured in (4) and ejection, shell case (30) withdrawed from outside the casing (1).

The utility model can reach the effect of the military shot of simulation, light, cigarette and percussion, ejection action, harmfulness one side when having avoided military rifle to launch blank cartridge again, the shell case of recycling emission also simultaneously prevents pack into live shell head and prevent with the bullet cartridge shooting is arranged with special gun barrel of shell case.
