Abstract
The utility model relates to an air pressure type firing device which comprises a shell body (1), wherein, one end of the shell body (1) is provided with an air bag chamber (3) provided with a piston (2), and the other end of the shell body (1) is provided with an ejecting tube (4); a positioning block (5) is arranged in the position in the air bag chamber (3) near the ejecting tube (4), and a brake piston (6) is arranged between the end face of the positioning block (5) and the end face of the shell body (1); the lateral position of the positioning block (5) is provided with a stop valve (7), and a relief valve (9) is arranged on the end face of the shell body (1) behind the brake piston (6). The utility model has the advantages of simple structure, convenient operation, and civil and military functions, and can conveniently transport articles or information within short range.
Description
The utility model relates to a kind of object conveying device, particularly is meant a kind of a kind of ejector of the object through airflight.
Be sent to another place after object flies generally speaking aloft, also very rare at present civilian, typical concrete instance is sent catapult or bow and arrow, be that bullet or rocket body are delivered to another place, but because ejection force is limited, object is generally very little or range is very limited, there is not more purposes in the reality, military aspect, firearms are typical concrete instances, but do not allow to occur the sound under a lot of particular cases, the phenomenon that smog etc. may expose is under a lot of specific civilian situations, as rock-climbing, cross over mountain stream, promptly recover or the like, need article delivery is difficult to the place that reach a period of time to another manpower, or, or transmit the urgent document or dispatch of a short distance with the another side of lanyard at mountain stream, all there is not desirable method now or device can solve the above problems.
Goal of the invention of the present utility model be disclose a kind of dual-use can the articles conveyed vapour-pressure type ejector of short distance.
Realize that technical solution of the present utility model is as follows: comprise ejector housing 1, housing 1 one ends are one to be provided with the airbag chamber 3 of piston 2, the other end of housing 1 is for launching pipe 4, be provided with locating piece 5 near the position of launching pipe 4 in the airbag chamber 3, be provided with brake piston 6 between locating piece 5 and housing 1 one end faces, one lateral location of locating piece 5 is provided with stop valve 7, is provided with pressure-reducing valve 9 on the end face of the housing behind the brake piston 61.At first projectile 8 is inserted ejector during use.Projectile 8 bottom faces are positioned locating piece 5 places, when promoting piston 2 by external force, because gas is compressible, increase along with pressure, air pressure had both acted on the bottom of projectile 8, act on an end of brake piston 6 again, the other end of brake piston 6 withstands on the side of projectile 8, because the face area of the brake piston 6 of design is much larger than the base area of projectile 8, when the gas in whole airbag chamber 3 is subjected to piston 2 to promote to high pressure, the pressure that the pressure that projectile 8 side direction are subjected to is subjected to much larger than projectile 8 bottoms, projectile 8 is an inactive state, when the pressure in the airbag chamber 3 reaches scheduled pressure value, start stop valve 7, stop valve 7, brake piston 6, the equivalent pressure cavity that formation one and airbag chamber 3 cut off between the end wall of locating piece 5 and housing 1, restart pressure-reducing valve 9, the instantaneous reduction of pressure in the above-mentioned equivalent pressure cavity, brake piston 6 is displacement backward automatically, and then projectile 8 launches pipe 4 and launches away in the effect lower edge of the instantaneous pressure difference of its base pressure.
Of the present utility model simple in structure, volume is changeable, be determined on a case-by-case basis fully, use also very convenient, can have multiple means to promote piston 2 makes airbag chamber 3 interior gases reach certain predetermined pressure, thereby reach a predetermined range and predetermined initial firing rate, can finish multiple dual-use task.
Provide embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, the detailed structure of embodiment of the present utility model is as follows, comprise ejector housing 1, the structure of housing 1 is an axial symmetric figure, housing 1 one ends are one to be provided with the airbag chamber 3 of piston 2, the lateral edges of piston 2 is provided with annular seal device 10, leak with the gas that reduces as far as possible between piston 2 and housing 1 inwall, the other end of housing 1 is for launching pipe 4, be provided with locating piece 5 near the position of launching pipe 4 in the airbag chamber 3, form a passage between locating piece 5 and the housing 1 one end inner faces, be provided with brake piston 6 in it, one lateral location of locating piece 5 is provided with stop valve 7, is provided with pressure-reducing valve 9 on the end face of the housing behind the brake piston 61.
During use, start stop valve 7, restarting 6 moments of 9 brake pistons of pressure-reducing valve retreats, its brake pressure that is applied to projectile 8 side direction is die-offed, projectile 8 bottoms still are subjected to the high pressure in the airbag chamber 3, then eject rapidly, for improve the time that projectile 8 is promoted by gas as much as possible in launching pipe 4, launch on pipe 4 inwalls and establish annular seal device 10, sealing device 10 sectionings, quantity are more than 2, and the spacing of adjacent sealing device 10 is slightly less than the length of projectile 8, so promptly guarantee projectile 8 and launch the sealing effectiveness of managing between 4, guarantee not many increase friction again.
The structure of aforesaid housing 1 is a ㄩ shape, and promptly the airbag chamber 3 of housing 1 is an axially parallel with launching pipe 4, so that carry, can one constitute between above-mentioned two parts, but also split connects.
In use, brake piston 6 presses projectile 8 suffered friction must be far longer than the propulsive force that projectile 8 is advanced gas pressure to produce, so the end face material of brake piston 6 is a rubber.In concrete the use, the pressure that makes piston 2 displacements can be multiple means, and simple mode can utilize manual jack to promote piston.Projectile 8 can be hollow, and its inside can be placed the article that need conveying on demand like this.
