Abstract

The invention relates to a light weapon, and especially a close-in compact pistol for self-defense or attack on the enemy. The compact pistol mainly comprises a barrel, a sleeve seat and handle assembly, and a magazine assembly. A ventilate-pipe is arranged on the barrel, and gunpowder fuel gas is utilized to enable the barrel to move forward, so as to complete an automaton cycle; the magazine is arranged on the lower part of the tail end of the barrel or the lower part of the front of the barrel, so as to effectively extend the barrel length of the compact pistol; and for counter-recoil of the barrel, a bullet guiding slope and a gun head cooperate to provide bullet by a ''shovel'' mode. According to the invention, a double action only can cooperate with a variety of firing mechanisms, so as to ensure security, omit manual insurance and realize firing before the enemy; the mechanism provided by the invention is simple and reliable, has a small volume, and adopts a novel barrel forward automatic mode; a percussion lock is fixed to avoid injury on the shooter in a narrow space or hand-to-hand combat shooting; and the compact pistol is suitable for usage by police and special agent.

Description

The compact pistol of gun barrel nose wheelie

One, technical field

The present invention relates to a kind of small arms, in particular for self-defence or attack enemy's close combat compact pistol.

Two, background technology

Volume is little because it has for compact pistol (Compact Pistol), light weight, be convenient to characteristics such as hidden portable, has more and more received people's attention.Each big well-known small arms manufacturer of the world all has it to design again or based on the improved compact pistol of full-scale pistol.China also develops the compact pistol based on 92 formula service pistols.

Make a general survey of present various compact pistol, its basic structure is all similar with full-scale pistol, accomplishes with sleeve recoil, bullet percussion back and takes out shell, ejection action, percussion lock and action such as wait to hit, and accomplishes next bullet when sleeve advances again and advances thorax.Free style gunlock or semi-free formula gunlock automated manner can be arranged, the gun barrel short recoil automated manner in addition of the big power bullet of application; The gunlock closedown mode is varied equally, turns round locking, utilizes powder gas locking etc. like inertia locking, locking lug swing locking, gun barrel revolution locking, the locking of gun barrel tail swing, gunlock.Aforementioned existing compact pistol all is to realize through reduction gun barrel, sleeve, handle size and capacity of macromolecule; But gun barrel is the primary clustering of firearms; It gives certain directive of bullet and initial velocity; Can obviously influence fire accuracy, and make gun propellant combustion insufficient if gun barrel shortens, increase muzzle sound, light, cigarette etc.Keep barrel length is a pair of contradiction that is difficult to be in harmonious proportion with reducing full rifle length as far as possible.

At present existing scholar carries out multiple trial and develops the compact pistol that has Long Barrel; Like the compact pistol of external certain type the magazine position is slightly moved forward; When the sleeve back seat; The ratchet that is arranged on the sleeve rear portion extracts one piece of bullet in the top in the magazine, and when sleeve advanced again, the ratchet swing made bullet align cartridge chamber and pushes away and springs into thorax.Though this mode makes that gun barrel is long and increases to some extent, the gun complex structure, the ammunition feed process is divided into two stages, as German mark ooze machine gun or Soviet Union PKM machine gun, can increase probability of failure like this, makes the gun unstable properties.

Three, summary of the invention

Keep barrel length when realizing shortening full rifle length as far as possible, and avoid gun structure complicated, the present invention to be intended to develop a kind of compact pistol with brand-new automated manner.

For reaching above-mentioned target, the compact pistol of gun barrel nose wheelie provided by the invention is taked following technical scheme:

Gas block is set on gun barrel, and the wireway direction backward down.Gas block the place ahead next-door neighbour's recuperator means, the rear cooperates with piston head.So-called piston head is the projection that is fixed on the receiver grip assembly in fact, and it cooperates with gas block makes gun barrel can under the powder gas effect, accomplish the preshoot action, because its position and function and traditional gas operated gun are similar, so name.

The receiver grip assembly is an overall structure, its be with the sleeve of conventional pistol comparatively speaking because traditional sleeve with recoil action of the present invention's cancellation, this assembly is temporary called after receiver grip assembly.Receiver grip assembly of the present invention holds recuperator means, percussion lock, gunlock head, cartridge case extractor, magazine etc.Wherein magazine is positioned at gun barrel tail end below or front lower place; The gunlock that makes conventional pistol be positioned at the magazine top is made way for gun barrel; Gun barrel just can obviously increase barrel length under the situation that does not increase complete strong rifle length after the gun front end extends to the magazine trailing edge always like this.

The present invention is owing to adopt brand-new gun barrel nose wheelie automated manner, and the automatic machine circulation is accomplished by gun barrel entirely, and the percussion lock dog is fixed, and has the simple and reliable characteristics of mechanism, and the injury that can avoid when small space or nearly body fistfight shooting to cause shooter.Trigger method can be taked hammer swinging or firing pin parallel-moving type; But in order to simplify the internal structure of an organization; The present invention is not provided with gun barrel preshoot interlock, makes percussion lock device to be hit, so the present invention adopts simple two trigger actions design, when so not only having guaranteed the portable security but also omitted manual safety; Make structure further simplify, and can accomplish that the enemy opens fire earlier.

Four, description of drawings

Fig. 2 is the side-looking structural representation of the compact magazine for firearms of gun barrel nose wheelie.

Five, the specific embodiment

In conjunction with detailed description of the drawings the present invention.The compact pistol overall structure of the present invention's gun barrel nose wheelie is as shown in Figure 1, it is characterized in that comprising gun barrel 1 and receiver grip assembly 3.Gas block 5 wherein is set on the gun barrel, and the wireway 6 in it can be derived the propellant powder combustion gas and made it to act on piston head 7, makes gun barrel 1 produce the preshoot action, compresses kicker 4 simultaneously.Be provided with in the receiver grip assembly 3 and take out the discharge that cartridge case extractor is accomplished empty-cartridge-case.After the gun barrel preshoot put in place, the one piece of bullet in the top got into armful bullet mouth position of abdicating in the magazine 8.Gun barrel advances under kicker 4 effects again; The guided missile slope 2 of its rear end will be in the bullet of embracing the bullet mouth and release backward; When playing root edge Collision gun head (end face of the receiver grip assembly relative after being locking) with cartridge chamber; Bullet is along being advanced into cartridge chamber on the guided missile slope, and this moves similar guided missile slope and cooperates with the gunlock head, " shovel " bullet of taking arms in magazine.

The compact pistol adapted of the present invention's gun barrel nose wheelie magazine is as shown in Figure 2, and it comprises magazine body 8, follower 10, magazine spring 11.It is characterized in that embracing the bullet mouth and be positioned at the magazine epistome, this is opposite with conventional pistol.

The specific embodiment of the invention is not limited to embodiment or the described form of accompanying drawing, and like the position of gas block, trigger method, closedown mode etc., all gun barrel preshoot automated manners of taking promptly belong to protection domain of the present invention.
