Description

Ail gun automatic hull withdraw mechanism and ail gun thereof

Technical field

The utility model relates to ail shooter technical field, is specifically related to ail gun automatic hull withdraw mechanism and ail gun thereof.

Background technology

Commercially modal ail shooter extracts at present, and device is managed by protective cover, nail, pressure cover spring, nail pipe connector sleeves, piston cylinder, rammer adapter sleeve, the stage clip that extracts, cartridge chamber body and the lid etc. that extracts form.Penetrate after distributing into, cartridge chamber body, piston cylinder under the effect of the stage clip that extracts, rapid return, shell case is entered extract in lid, operating personnel need to pull piston cylinder that shell case is dropped from the lid that extracts; The trajectory hole covered owing to extracting is just slightly larger than shell caliber; the phenomenon got stuck often is there will be in the process of extracting; when operator pulls piston cylinder; need to rock ail gun back and forth toward contact; shell case just departs from the lid that extracts; make the operation inconvenience very that extracts, the labour intensity of operator is also larger simultaneously.

Utility model content

For above-mentioned deficiency of the prior art, the utility model provides the ail gun automatic hull withdraw mechanism that a kind of structure is simple, accurately automatically can exit shell case.

In order to reach foregoing invention object, the technical solution adopted in the utility model is:

First aspect, provide a kind of ail gun automatic hull withdraw mechanism, it comprises:

Ejection cover, it has the inner chamber holding cartridge chamber body, and ejection is overlapped one end and is provided with the arc that has arcuate socket; The camber of arc is less than the radius of ejection cover;

Cartridge chamber body, one side end is provided with the arc boss that has arcuate socket, and the end winding support of end side and piston cylinder is socketed;

Stage clip circle, its one end is connected with the end winding support of ejection cover away from arc, stage clip circle and ejection are overlapped the end that contacts and cartridge chamber body are embedded by a spring inner chamber that ejection overlaps, and the arcuate socket on arc and the arcuate socket on arc boss are spelled form firing pin via hole.

Second aspect, provides a kind of ail gun, and it comprises ail gun housing and ail gun automatic hull withdraw mechanism, and ail gun automatic hull withdraw mechanism is arranged in the outer sleeve body of ail gun housing forward end with being provided with after the piston cylinder following closely pipe is fixedly installed togather; Outer sleeve body lower end has the position limiting structure of the chute relative sliding arranged with piston cylinder.

The beneficial effects of the utility model are: this cartridge case extractor and ail gun are departed from from ejection cover by spelling group arc to be together separated formation one cavity and spring return zone of action with arc boss shell of moving, because the volume of cavity is much larger than the size of firing pin via hole, overcome the problem getting stuck and need operator to rock back and forth in ejection process; Also reduce the operational sequence of workman simultaneously, thus reduce the labour intensity of operator.

Detailed description of the invention

Below detailed description of the invention of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.

The decomposition view of ail gun automatic hull withdraw mechanism 2 is shown referring to figs. 1 to Fig. 3, Fig. 1; Fig. 2 shows ail gun automatic hull withdraw mechanism 2 and the decomposition view having the piston cylinder 23 of following closely pipe 22 and be placed in together; Fig. 3 show ail gun automatic hull withdraw mechanism 2 with have the piston cylinder 23 following closely pipe 22 fit together after structural representation.

As shown in Figure 1 to Figure 3, this ail gun automatic hull withdraw mechanism 2 comprises ejection cover 27, cartridge chamber body 26 and stage clip circle 24.

Wherein, ejection cover 27 has the inner chamber holding cartridge chamber body 26, and its one end inwall is provided with one section of internal thread, and ejection is overlapped 27 other ends and is provided with the arc 271 that a piece has an arcuate socket.

As shown in Figure 5 and Figure 6, the camber of arc 271 is less than the radius of ejection cover 27, accurately automatically exits in order to ensure shell case, selects the camber of arc 271 than the radius little 3mm at the most of ejection cover 27 during design.Wherein, the center of circle of the arcuate socket on arc 271, arc 271 and ejection cover 27 overlaps.

With reference to figure 1 and Fig. 4, cartridge chamber body 26 1 side is provided with the arc boss 261 that has arcuate socket, end side is provided with the external thread section be socketed with piston cylinder 23 end, and during use, cartridge chamber body 26 is socketed by the male end at this place and the end winding support of piston cylinder 23.

Refer again to Fig. 1, stage clip circle 24 is set in piston cylinder 23 end, its one end away from piston cylinder 23 has the external thread section of the screw-internal thread fit of to overlap 27 with ejection, and during use, stage clip circle 24 overlaps 27 by the external thread section at this place and ejection and is connected away from the end winding support of arc 271.

Stage clip circle 24 and ejection are overlapped 27 ends contacted, by a spring 25, cartridge chamber body 26 are embedded the inner chamber that ejection overlaps 27, due to the elastic force of spring 25, and the arcuate socket on arc 271 and the arcuate socket on arc boss 261 are spelled form firing pin via hole 28.

As shown in Figure 7, this ail gun comprises the ail gun automatic hull withdraw mechanism 2 that ail gun housing 1 and Fig. 1-Fig. 6 described, and ail gun automatic hull withdraw mechanism 2 is arranged in the outer sleeve body 11 of ail gun housing 1 front end with being provided with after the piston cylinder 23 following closely pipe 22 is fixedly installed togather; Offer a chute 231 in the lower end of piston cylinder 23, outer sleeve body 11 lower end has the position limiting structure 12 of chute 231 relative sliding arranged with piston cylinder 23.One is installed with for the nail pipe box 21 protected of end to nail pipe 22 in the front end of nail pipe 22.

Below the relevant action extracted is described in detail:

After ammunition has been launched, operator pulls piston cylinder 23, the cartridge chamber body 26 be fixed together with piston bush travels forward, make spelling group arc 271 together be separated formation one cavity with arc boss 261 to spring 25 1 pressure, shell case enters arc 271 under gravity and is separated with arc boss 261 in the cavity of formation in cartridge chamber body 26 simultaneously; Unclamp piston cylinder 23, due to the return of spring 25, make cartridge chamber body 26 towards the motion of arc 271 place, make shell case come off in cavity and realize automatic hull withdraw process.

To sum up above-mentioned, adopt this programme to carry out ejection, there will not be the problem got stuck in ejection process, more can not there is need operator to rock back and forth problem that ail gun carries out ejection; The operational sequence of reduction workman, reduces the labour intensity of operator.
