Abstract

The invention discloses a small-bore tear-gas shell which is mainly used in the field of anti-riot. The small-bore tear-gas shell comprises a shell case, a primer, a gun propellant and a tear-gas pill component. The primer is embedded in the bottom hole of the shell case, and the gun propellant and the tear-gas pill component are arranged upwards in sequence from the bottom of the shell case. One end of the tear-gas pill component is a plastic tail wing, and the other end is a rubber capsule filled with the tear-gas agentia. The rubber capsule is embedded in a base of the tail wing, adhered firmly by the glue and fixed by a pin. The pill only cracks when crashing into the target, then the tear-gas mixture is sprayed out to form a stream of tear-gas smoke to conquer the target depending on the irritant effect of the tear-gas agentia. The small-bore tear-gas shell matches with the 10 mm anti-riot pistol, has the advantages of reasonable design, simple structure, good safety and reliability, stable performance, no serious injury to the target and the like, can protect the user safety as well as effectively restrain the illegal criminals, and is the single police equipment having the characteristics of primary self-defense and protection, and both offensive and defensive purposes.

The specific embodiment

The invention provides a kind of a kind of small-bore tear bombnoun that closely use, the nominal bore is preferably 10mm, and cooperates the 10mm Anti-Riot Pistol to launch use, is mainly used in and disperses the interior riot crowd of 15m distance, hits and the interior law-breaker of uniform 5m.

As shown in Figure 1, body structure provided by the invention comprises shell case 1, and the fire in a stove before fuel is added 2, propellant powder 3 and tear-gas bullet assembly 4 are housed from the bottom to the oral area in this shell case 1 successively.

And the structure of tear-gas bullet 4 as shown in Figure 2, comprises bullet empennage 41, pin 42, stifled 43, dacryagogue 44 and bullet housing 45.

Shown in Fig. 2, Fig. 3, Fig. 3 A, this bullet empennage 41 is to be made by polythene material, its tail end is provided with the dimple 411 of the thin-walled that a longitudinal cross-section takes the shape of the letter U, head end is provided with a relative darker longitudinal cross-section shrinkage pool 412 that take the shape of the letter U, that wall is thicker, the outer wall shape of this head end and tail end and the inner wall shape of this shell case 1 match, and the lateral cross section shape of the part between this head end and the tail end is " ten " font 413.As can see from Figure 1, be filled with described propellant powder 3 in the enclosure space that forms between the bottom of the inwall of the dimple 411 of this tail end, this shell case 1 and this shell case 1.

By as can be known shown in Figure 4, described stifled 43 is to be made of metal, and its head 431 is taper entities, and afterbody 432 is that (wall thickness is about 0.3～0.5mm) sleeve to a thin-walled.

By shown in Fig. 5, Fig. 5 A as can be known, this bullet housing 45 is frangible rubber parts, after promptly in General Purpose Rubber, adding the iron powder of a certain amount of (part by weight is about gross weight 50～60%), be processed into bigger, the frangible rubber parts of a kind of fragility through common vulcanizing treatment again, this bullet housing 45 has an openend 451 and a blind end 452, very thin (the wall thickness about 0.4～0.8mm) of barrel, the end thickness of blind end 452 is thicker than barrel, and the end surface shape of this blind end 452 is a tack, and the groove 453 of the prefabricated cracking of " a ten " font is arranged on this tack.Certainly, this bullet housing also can select for use frangible plastic material to substitute.

In conjunction with Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, described tear-gas bullet assembly 4 makes up in the following way, the dacryagogue 44 of dry powder shape is positioned in the blind end 452 of bullet housing 45, in this bullet housing 45, pack stifled 43 again into, stifled 43 head 431 contacts with dacryagogue, afterbody 432 flushes with the openend 451 of this bullet housing 45, thereby dacryagogue is packaged in the bullet housing 45, next, the openend 451 of bullet housing 45 is worn and is glued in the set shrinkage pool 412 of the head end of this bullet empennage 4, openend 451 at this bullet housing 45 radially bores a through hole with the position of these shrinkage pool 412 sockets again, this through hole passes the sidewall of this shrinkage pool 412 successively, the sidewall of the openend 451 of bullet housing 45, and the sidewall of this afterbody 432 of stifled 43, described pin 42 is arranged in this through hole, with this bullet empennage 41, stifled 43 are connected with bullet housing 45 threes and fix, and make it to become a tear-gas bullet assembly 4.

Action principle of the present invention is: when using rifle to launch this bullet, the firing pin percussion fire in a stove before fuel is added 2 of rifle, the fire in a stove before fuel is added 2 propellant 3 that ignites, make tear-gas bullet assembly 4 with certain speed directive target, bullet housing 45 explosion when colliding to target, dacryagogue 44 is spilt, form one tear-gas smog, rely on the spread effect of dacryagogue to subdue target.

More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within protection scope of the present invention.
