Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, Figure 2 with shown in Fig. 5, the muzzle attachment that a kind of rifle and tommy gun use, in a tubular form, described muzzle attachment comprises this muzzle attachment: for be connected with gun barrel 2 linkage section 11, for reduce the shock wave that ballistic projections produces the system section of moving back 12, for reducing anti-jump section 13 that muzzle is beated.The described system section of moving back 12 is arranged between linkage section 11 and anti-jump section 13.Described linkage section 11 sidewall is provided with thorax mouth pin-and-hole 113.With a thorax mouth pin 3, its part is arranged in thorax mouth pin-and-hole 113, and another part is arranged on gun barrel 2, for connecting gun barrel 2.The sidewall circumferencial direction of the described system section of moving back 12 is evenly provided with many row's steam vents 121, and its direction, aperture tilts to linkage section 11.The sidewall of described anti-jump section 13 is provided with rectangular opening 131, and its direction, aperture tilts obliquely, and the lower wall of rectangular opening 131 is wider than upper side wall.
As shown in Figure 1 and Figure 2, the external diameter of this muzzle attachment is standard size, the circumferencial direction of described linkage section 11 sidewall is provided with the first annular groove 111 and the second annular groove 112, distance is left between first annular groove 111 and the second annular groove 112, described thorax mouth pin-and-hole 113 is arranged between the first annular groove 111 and the second annular groove 112, and described first annular groove 111 and the second annular groove 112 can be used for the muzzle howitzer installing obstructed bore.
As described in Figure 5, described thorax mouth pin-and-hole 113 is arranged on the bottom of linkage section 11, and a part for thorax mouth pin 3 is arranged in thorax mouth pin-and-hole 113, and another part is arranged on gun barrel 2.
As shown in Fig. 2, Fig. 6 and Fig. 8, in the present embodiment, described steam vent 121 is circular hole, and is provided with four rows, and the circumferencial direction along the system section of moving back 12 sidewall is uniformly distributed, and described steam vent 121 is often arranged and is provided with three.Described steam vent 121 is ɑ, ɑ=120 ° with the angle of tube bore axis.
The installation method of muzzle attachment of the present utility model: as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 7, gun barrel 2 oral area is inserted muzzle attachment 1, after installing to correct position, ensure that the upper and lower sidewall inner plane of rectangular opening 131 of muzzle attachment 1 is in the direction with plane-parallel, bore a transverse direction and run through according to the muzzle attachment 1 mouthful pin-and-hole 113 that loads and joining of gun barrel 2 do hole, then with thorax mouth pin 3, muzzle attachment 1 and gun barrel 2 are fixed up, namely complete the installation of muzzle attachment 1.
Muzzle attachment system of the present utility model is moved back, anti-jump principle: as shown in Fig. 2, Fig. 4 and Fig. 8, after powder gases enters the system section of moving back 12 of muzzle attachment 1 by gun barrel, part gas sprays from steam vent 121, because the direction, aperture of steam vent 121 tilts to the linkage section 11 of muzzle attachment 1, thus to rifle body generation active force forward, stop rifle body recoil, realization system moves back function; Part gas enters anti-jump section 13 shown in Fig. 4 from central shell hole, and as shown in Figure 7, because the lower wall of rectangular opening 131 is wider than upper side wall, powder gases sprays the downward active force of rear generation from rectangular opening 131, thus reduction muzzle is beated, and realizes anti-bouncing function.
