Abstract

The invention discloses a capturing net micro-acoustic emission device. An inner pipe (7) is connected to an outer wall of a connecting pipe (2); a net barrel (4) is connected to an outer wall of the inner pipe (7); a capturing net (17) is arranged in a capturing net mounting cavity which is formed between the inner pipe (7) and the net barrel (4); retainer rings (8) are fixed at an opening of the inner pipe (7) through a retainer ring groove (16); a supporting plate (6) is connected to a spiral groove (18) of the inner pipe (7) through a guide pin (13); a steel ball (11) is arranged on an outer wall of the supporting plate (6) through an R-shaped groove (12); a powder box (3) is arranged in a space formed by the inner pipe (7), the supporting plate (6) and the connecting pipe (2); the supporting plate (6) is fixed with a traction head (5) through the steel ball (11); the capturing net (17) is connected with the traction head (5); and an opening of the net barrel (4) is pressed and covered by an end cover (9). During emission, the supporting plate always seals gunpowder gas in the inner pipe to achieve silent or micro-acoustic, smoke-free and flame-free emission, the recoil force is small, and a user has higher hiding capacity.

Description

Catch the little acoustic emission device of net

Technical field

The present invention relates to emitter, be specifically related to catch the little acoustic emission device of net.

Background technology

As everyone knows, catching the net rifle is a kind of nonlethal weapon, and a kind of equipment of arresting that to be army, People's Armed Police, public security use when carrying out the combat duty such as explosion-proof, stability maintenance, anti-terrorism is mainly used in catching the living aim in 4～11 meters scopes.At present, similar products at home and abroad in use shot noise is excessive, because noise Da Yi sticks one's chin out.

Summary of the invention

The object of the invention is to: a kind of little acoustic emission device of net of catching is provided, in carrying out combat duty, realizes noiseless or little acoustic emission, avoid the large phenomenon of shot noise, when finishing combat mission, do not stick one's chin out again, reach self-protection.

The used scheme of technical solution problem of the present invention is: this catch the net emitter by ejecting gun, catch the net bullet and form, catch the net bullet and be installed in to consist of on the ejecting gun and catch the net emitter; The described net bullet of catching comprises tube connector, medicine box, the net cylinder, inner tube, drawing head, supporting plate, end cap and catching net, inner tube is threaded on the outer wall of tube connector, connection network cylinder on the outer wall of inner tube, form the catching net installation cavity between inner tube and the net cylinder, catching net is placed in the catching net installation cavity, the inner tube oral area has circlip groove, in circlip groove, fix the back-up ring of two symmetries, establish helicla flute on the inwall of inner tube, supporting plate is connected on the helicla flute of inner tube through guide finger symmetrical on the outer wall, establish one group of R shape groove on the outer wall of supporting plate, the steel ball of projection is installed in the R shape groove, in inner tube, the installation medicine box is established the locating hole that is complementary with steel ball in the space that supporting plate and tube connector form on the outer wall of drawing head, on the supporting plate through steel ball fixed traction head, drawing head is packed in the inner tube, catching net connects drawing head, and push rod compresses the Rubber end of drawing head end, the oral area gland upper end cover of net cylinder.

During use, ejecting gun is connected with tube connector and lock, pull the ejecting gun trigger, the fire in a stove before fuel is added of firing pin bump medicine box, medicine burns rapidly and forms the high pressure powder gas, and the guide finger that promotes supporting plate drives drawing head along the forward accelerated motion of helicla flute of inner tube, is blocked and stop motion by back-up ring when supporting plate moves to the inner tube oral area, drawing head separates the inner tube that flies out with supporting plate under the effect of inertia force, realizes fully opening of catching net.

The net emitter of catching of the present invention is in whole emission process, supporting plate is enclosed in powder gas in the inner tube all the time, make catching net reach noiseless or little sound, smokeless, nonflame when emission, and the emission recoil is less, when carrying out the special duty situation, user's disguise is stronger.
