Description

The only head bullet of Shotgun

Technical field

The utility model belongs to Shotgun technical field, is specifically related to the only head bullet of a kind of Shotgun, is applied in gun barrel and does not have on the smooth bore Shotgun of rifling.

Background technology

Shotgun is the musket not having rifling in a kind of gun barrel, and the sub warhead launched can not rotate, and the bullet bullet of Shotgun is made up of a several extremely hundreds of spherical dust-shot.The gun pressure of canister shot bullet is lower, and the overall bullet of canister shot is heavier, and muzzle velocity is not high, and the dust-shot ability of velocity keeping disperseed after going out thorax is limited, terminal ballistics only about 100 meters, coverage about 50 meters.

In order to improve power and the shooting coverage of Shotgun, people have developed the only head bullet of multiple Shotgun, warhead form is from spherical cylindrical to ball roller shape, tip, cylindrical etc. varied with helical angle empennage tip, the bullet of these shapes has larger air drag when flying, and micro-the revolving produced during bullet flight also realizes by increasing bullet advance resistance, these warhead forms tail end when flying has stronger eddy current, thus affect the ability of velocity keeping of bullet, affect flying distance, reduce firing density.Existing bullet is all generally make with lead alloy material, and unfavorable environmental protection, armor-penetrating ability is limited.

Utility model content

The utility model provides a kind of Shotgun only head bullet, reduces air drag, maximally utilises the kinetic energy that propellant powder is given, have good ability of velocity keeping, and in whole ballistic flight process, only head bullet does not roll all the time.

The technical solution of the utility model is, the only head bullet of a kind of Shotgun comprises the fire in a stove before fuel is added, base, propellant powder, shell case, bullet holder, bullet and bullet jacket; The afterbody of bullet is cone, and the head of bullet is hemisphere, and the middle part of bullet is cylinder, the transition of cone, cylinder and hemisphere nature; Base is fixed on one end of shell case, the coyote hole of shell case inner chamber and fire in a stove before fuel is added front portion is through, the centre bore of base is built with the fire in a stove before fuel is added, in the coyote hole that propellant powder and bullet holder load base successively and shell case, the anterior conical bore of bullet holder is equipped with the afterbody cone of steel bullet, head hemisphere and the middle part cylinder of bullet are positioned at bullet jacket, one end of bullet jacket is three prefabricated broken valve structures, the head of bullet is covered by bullet jacket, and held tightly by three prefabricated broken lobes, bullet jacket is contained in the other end of shell case, and bullet jacket and shell case junction are compressed by the seal bead of shell case.

The beneficial effects of the utility model are, 1) muzzle energy of canister shot to be concentrated with only head bullet and is acted on only bullet 6 by the utility model Shotgun, the operating distance of Shotgun and power is expanded, has very strong power; 2) the utility model short range operations has and well fails, and hundred meters of distances can puncture 4 millimeters of steel plates by punched holes type, can make closely anti-equipment bullet and use; 3) the utility model Shotgun warhead form structure of only head bullet and assembling mode can ensure after transmitting, when not being applied to bullet rotation function, bullet can reduce air drag by self smooth smooth-going outer surface, maximally utilise the kinetic energy that propellant powder is given, there is good ability of velocity keeping, do not roll all the time in whole ballistic flight process.

Accompanying drawing explanation

This description has 2 width accompanying drawings

Fig. 1 is the structural representation of the utility model Shotgun with only head bullet;

Fig. 2 is that the A-A of Fig. 1 is to profile.

Detailed description of the invention:

As depicted in figs. 1 and 2, the only head bullet of the utility model Shotgun comprises the fire in a stove before fuel is added 1, base 2, propellant powder 3, shell case 4, bullet holder 5, bullet 6 and bullet jacket 7.The profile of bullet 6 is streamlined, and namely the afterbody of bullet 6 is cone, and the head of bullet 6 is hemisphere, and the middle part of bullet 6 is cylinder, the transition of cone, cylinder and hemisphere nature.The bullet 6 of hemisphere on low velocity of bullet 6 affects not quite, and pointed cone projectile tail portion does not produce eddy current.There is no this very most of resistance of afterbody eddy current, improve ability of velocity keeping and improve closeness.

As depicted in figs. 1 and 2, base 2 is fixed on one end of shell case 4, the coyote hole of shell case 4 inner chamber and the fire in a stove before fuel is added 1 front portion is through, the centre bore of base 2 is built with the fire in a stove before fuel is added 1, in the coyote hole that propellant powder 3 and bullet holder 5 load base 2 successively and shell case 4, the anterior conical bore of bullet holder 5 is equipped with the afterbody cone of steel bullet 6, bullet holder 5 rear portion is provided with obturator ring structure, head hemisphere and the middle part cylinder of bullet 6 are positioned at bullet jacket 7, one end of bullet jacket 7 is three prefabricated broken valve structures, the head of bullet 6 is covered by bullet jacket, and held tightly by three prefabricated broken lobes, bullet jacket 7 is contained in the other end of shell case 4, and bullet jacket 7 and shell case 4 junction are compressed by the seal bead of shell case 4.

Bullet 6 adopts hardened steel to make, and cost is low, environmental friendliness, and the blunt warhead form of bullet 6 head to the more energy of target transmission, can puncture 4 millimeters of steel plates at hundred meters of distance punched holes types than pointed bullet.

Bullet holder 5 adopts low density polyethylene (LDPE) manufacture, and rear portion is provided with obturator ring, and front central has the conical bore holding bullet 6 tapered segment, and bullet holder 5 is for transmitting the kinetic energy of propellant powder 3 generation to bullet 6.After percussion, gun barrel wall is close in the inertia extruding that the obturator ring part at bullet holder 5 rear portion and the circumferential section holding bullet tail cone hole are above subject to bullet 6, add the seal of gun barrel 3, bullet holder 5 beyond bullet 6 delivery to the outer aftereffect accelerating region of muzzle, can be conducive to the initial velocity and the firing density that improve bullet 6.

Bullet jacket 7 adopts low density polyethylene (LDPE) manufacture, coordinates, good leak tightness with the edge curling seal of bullet 6 and shell case 4.The cylindrical section of bullet jacket 7 inner circumferential coordinates with the middle part cylindrical section of bullet 6, ensures the axis of bullet 6 and the dead in line of gun barrel 3, to ensure bullet 6 go out the flight stability after thorax and firing density most important.And can ensure bullet 6 outer wall not with gun barrel inwall direct friction.

Bullet jacket 7 circumferentially trisection longitudinally has three prefabricated broken lobe grooves, forms three prefabricated broken valve structures, and after bullet 6 goes out thorax, very fast the opening along prefabricated broken lobe groove of the bullet jacket 7 that density ratio bullet 6 is low departs from bullet 6.

The course of work of the present utility model is, during shooting, the fire in a stove before fuel is added 1 is pulled the trigger, and ignite gases at high pressure that propellant powder 3 produces promote bullet holder 5, bullet 6, bullet jacket 7 wash shell case 4 open seal bead of the fire in a stove before fuel is added 1 enters bore and goes out gun barrel mouth, completes emission process.
