Abstract
The utility model relates to a gun quick firing air pressure counterrecoil mechanism, and comprises a gun-barrel, a gun bolt, a gas orifice, a return pipe, an air vent, a gas return pipe piston and a recoil spring. The recoil spring is enclosed on the rear end of the return pipe piston; the end of the gas return piston is connected with the gunlock; the return piston also comprises a waste gas duct, a waste gas receiver, an inlet non-return valve, an exhaust counterrecoil non-return valve, a cylinder barrel and an air pressure crown bar. By adopting the technical proposal, the utility model can not only improve the rate of firing, but also reduce the percussive force of a blowback during firing through two way operation of air current; under environmental extremes, foreign matters, such as silt, dust and branch and so on, enter a cartridge receiver and deposit on a guide of an automatic machine, and bring great resistance for counter-recoil of the gun lock; the device significantly improves the acting force of the gun bolt to move forward, can not only overcome the resistance, but also reduce or eliminate unsmooth operation of the gun bolt and even jamming or obstruction of cartridge.
Description
Technical field
The utility model relates to the rapid fire mechanism of rifle in the conventional weapon, machine gun or cannon, particularly relates to a kind of firearms rapid fire air pressure counterrecoil mechanism.
Background technology
In the prior art, in the light-duty conventional weapon that each country makes, all adopted gas port and piston to promote gunlock in the automatic rifle that can launch continuously, machine gun and the cannon, promote gunlock backward, the compression kicker, finish unblank, ejection, and make hammer become arm-to-arm backward; Expansion force by kicker, gunlock is travelled forward, promote a bullet bore, finish locking and enter the position again, because the expansion force of kicker and the restriction that reaction speed is subjected to the condition of spring own, make existing speed of launching continuously only at 4-12/second at gun, firearms are under adverse circumstances in addition, foreign matter such as silt and dust often enters casing and is deposited on the automatic machine guide rail from shell throwing-out window, the expansion force of kicker is little, can not overcome these resistances, thereby cause the gunlock motion not smooth, even the phenomenon of card bullet, stagnant bullet takes place.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of gun action reset mechanism of can fast reaction upholding, and can overcome by, other resistance that foreign matters such as silt and dust bring advances the deficiency that exists in the technology again thereby remedy existing gun.
The technical scheme in the invention for solving the above technical problem is: a kind of firearms rapid fire air pressure counterrecoil mechanism, it comprises gun barrel, gunlock, gas port, muffler, steam vent, the muffler piston, kicker, the front portion of described gun barrel is provided with gas port, gas port links to each other with muffler, be provided with the muffler piston in the muffler, the tube wall of muffler is provided with steam vent, described muffler piston rear sleeve is equipped with kicker, its afterbody links to each other with gunlock, it also includes waste gas duct, the waste gas air storage chamber, breather check valve, check valve is advanced in exhaust again, cylinder barrel and gas-pressure mandril, described waste gas duct is fixed on the steam vent, and it is coupled logical, the other end of waste gas duct is connected with air storage chamber through breather check valve, and described gas-pressure mandril is arranged on the rear portion end face of gunlock, and described waste gas air storage chamber is arranged on the rear of gunlock, the waste gas air storage chamber is provided with and the corresponding cylinder barrel of gas-pressure mandril, is provided with the exhaust of waste gas air storage chamber Joint at the cylinder barrel inner bottom part and advances check valve again.
Described cylinder barrel endoporus arranged outside has the guiding groove, and the length of described gas-pressure mandril is greater than the length of cylinder barrel.
Firearms rapid fire air pressure counterrecoil mechanism of the present utility model when carrying out ball firing, cocking, the trigger pull bar sear of leaving behind, firing pin is hit in the hammer translation forward, and firing pin bump bullet primers is lighted propellant powder, produce powder gases, push bullet and travel forward along rifling, when bullet process gas port, the part powder gases passes through gas port, pour muffler, impact the muffler piston, drive gunlock move backward finish unblank, ejection work, and make hammer become arm-to-arm backward; This moment is when the muffler piston moves backward, open steam vent, waste gas pours in and deposits in the waste gas air storage chamber through steam vent and waste gas duct through breather check valve, gunlock falls back on rear, the gas-pressure mandril that is fixed on the gunlock enters in the cylinder barrel that is provided with its opposite position, continue to retreat, the gas-pressure mandril roof pressure impinges upon exhaust and advances on the check valve again, make exhaust advance one-way valve opens (recoil puts in place) again, gases at high pressure are released goes out the waste gas air storage chamber, promote gas-pressure mandril and gunlock and travel forward, promptly gunlock advances again; Promote a bullet and enter bore, finish locking and put in place, the percussion of awaiting orders; Realize the work of continuous high speed shooting of the present utility model.
The beneficial effects of the utility model are: a kind of firearms rapid fire air pressure counterrecoil mechanism, pass through the technical program, it not only can effectively improve firing rate greatly, recoil impact in the time of can also reducing to shoot by the two-way operation of air-flow, under adverse circumstances, silt and dust often enter casing and are deposited on the automatic machine guide rail from shell throwing-out window, give the huge resistance of multiple forward (FWD) of gunlock, thereby it is not in place to cause gunlock to advance again, causes and can not treat the thorax percussion; This device has then improved the proal active force of gunlock greatly, not only can effectively overcome these resistances, obstacle, and can reduce or obstacle that the motion of the gunlock stopping to cause therefrom is not smooth and even the card bullet that takes place, stagnating plays phenomenon.
