Description

Little recoil automatic pistol

Technical field

The present invention relates to a kind of pistol, especially a kind of automatic pistol of little recoil belongs to military weapon technical field.

Background technology

In the existing pistol technology, pistol is difficult to the big power bullet of emission, and the recoil is very big, be difficult for fixed fire, particularly several pistols of the common use of I public security People's Armed Police can only be used for tackling closely single target, if distance is far away slightly, or under against heavy odds the situation, existing pistol then power subtracts greatly.

Summary of the invention

Technical problem to be solved by this invention is to overcome deficiency of the prior art, and a kind of reliable locking that has is provided, and air shock absorption can be launched multiple bullet, or even little recoil automatic pistol of shot.

Technical problem to be solved by this invention is achieved through the following technical solutions; A kind of little recoil automatic pistol, be by gun barrel 2, big recuperator means 4, gunlock 26, little recuperator means 12, the body of a gun 25, magazine 24, percussion lock 27 are formed, it is characterized in that being fixed with outside gun barrel 2 middle parts pipe skirt 3, after gas port 6 and locking convex slot 7 are arranged, big recuperator means 4 is coated at gun barrel 2 middle parts, and gunlock 26 is the middle part in the body of a gun 25, and its machine bolt 11 is cylinder, the upper end can hold little recuperator means 12, installation body 10 in the lower end, body 10 front portions are thicker cylinder, there are protruding bamboo shoot 9 side, it is thin cylinder that there are a step, rear portion in the middle part.The body of a gun 25 front portions are equipped with body of a gun protecgulum 1 and body of a gun bonnet 13 respectively with the rear portion.The body of a gun 25 middle parts have front wide and rear narrow, what the middle part was gentle slope shape frees convex slot 8, magazine 24 is 92 formula magazine for firearms roughly the same, percussion lock 27 is positioned at the body of a gun 25 postmedians, hammer 15 is positioned at gunlock 26 back lower places with mainspring 14, sear 17 middle parts are the cucurbit space, in oval safety 16 is housed, sear has sear spring 18 under the left side, guide rod 19 is positioned at sear 17 sides, and it is tangent with the sear rear portion that it colludes end, and trigger 23 is housed before it, guide rod spring 20 is equipped with in the rear end, and fulcrum 22 is arranged in the intermediate support groove 21.

A kind of little recoil automatic pistol is characterized in that there is alignment pin 5 gun barrel 2 rear ends to managing between the skirt 3, moves forward and backward in the body of a gun 25 front end chambeies for making gun barrel 2, can not roll in the body of a gun 25 front end chambeies.

A kind of little recoil automatic pistol is characterized in that machine bolt 11 lower rear have a projection and the body of a gun 25 interlocks, and machine bolt 11 is moved forward and backward in the chamber, can not rotate in the chamber, and can form fixed fire with sear 17 collisions.

A kind of little recoil automatic pistol, the joining place that it is characterized in that body 10 and machine bolt 11, body 10 has the teeth groove that is the rotation of going up a slope, machine bolt 11 has the teeth groove that is the descending rotation, its between cog closed with stagger, can make changes on the body and changes down, when gunlock 26 travels forward, body 10 is the between cog closure under the extruding of machine bolt 11, protruding bamboo shoot 9 form locking with locking convex slot 7, when gunlock 26 moves backward with gun barrel 2, after protruding bamboo shoot 9 are clashed into the gentle slope of convex slot 8, after body 10 staggered with machine bolt 11 between cog, formation was unblanked.

A kind of little recoil automatic pistol, when it is characterized in that triggering pulling 23, the end that colludes of guide rod 19 collides sear 17, hammer 15 percussions, that unclamps trigger 23 back-guiding rods 19 colludes end under the pulling force of guide rod spring 20, does not collide sear.

The present invention compared with prior art has following beneficial effect, can launch big power bullet, but fixed fire, but single-shot, change gun barrel and can launch multiple model bullet, especially shot, the recoil is little, light weight, hit rate is higher, and parts are also less, and size and five Chinese style pistols are approaching.

Description of drawings

Accompanying drawing 1 is little recoil automatic pistol integral planar structural representation, and accompanying drawing 2 is the whole cross-sectional view of little recoil automatic pistol, and accompanying drawing 3 is the whole component structural schematic diagrames of little recoil automatic pistol.

Among the figure: 1, body of a gun protecgulum 2, gun barrel 3, pipe skirt 4, big recuperator means 5, alignment pin 6, gas port 7, locking convex slot 8, free convex slot 9, protruding bamboo shoot 10, body 11, machine bolt 12, little recuperator means 13, body of a gun bonnet 14, mainspring 15, hammer 16, insurance 17, sear 18, cloudy iron spring 19, guide rod 20, guide rod spring 21, pivot slot 22, fulcrum 23, trigger 24, magazine 25, the body of a gun 26, gunlock 27 percussion locks

The specific embodiment

Triggering pulling 23, the projection of the projection bump sear 17 of guide rod 19, sear 17 front ends move downward, free hammer 15, hammer 15 clashes into firing pin under mainspring 14 elastic force, the bullet blast, produce gases at high pressure simultaneously, the propelling movement bullet travels forward, and when bullet passed through gas port, a part of gases at high pressure entered gas port, arrive in the chamber outside the gun barrel 2, gun barrel 2 also moves backward with gunlock 26 simultaneously, and pipe skirt 3 these intracavity gas of compressing hinder gun barrel 2 and gunlock 26 moves backward, manage external resistance because gun barrel 2 active force backward is a bit larger tham it, and slowly motion backward, after group ejected thorax, its surplus energy still made gun barrel 2 and gunlock 26 move backward, and protruding bamboo shoot 9 are through unblanking behind the gentle slope, gunlock 26 moves backward under the residue kick and finishes ejection and press the inferior bullet of sending out to go into thorax, gun barrel 2 resets under big kicker effect, and insurance this moment must be unclamped trigger if fix on single-shot, triggering pulling again could be launched next bullet.

If want fixed fire, the insurance right side turn 90 degrees, the same when running initially with single-shot, in the time of inferior, pull bar 19 draws sear 17 to move forward a bit, because the elastic force of sear spring 18, sear 17 front ends have moved up a bit, and press sear 17 front ends during gunlock 26 returns this moment, and free hammer 15, form fixed fire.
