The technical scheme that realizes the utility model object is:
A caseless cartridge for compatible existing firearms to greatest extent, comprises body, propellant powder and the fire in a stove before fuel is added of hollow, unlike the prior art: also comprise movable root edge and underseal; The center of body is provided with the cylinder that cross section is circle or regular polygon, and cylinder afterbody is hollow, for placing the fire in a stove before fuel is added; Propellant powder is arranged on cylinder around in the cavity of body; The afterbody opening of body, opening part is provided with T-shaped groove for fixing movable root edge; Underseal is located between cylinder afterbody and projectile tail opening.
Described dump bottom cause is mated equipped chassis and jump ring composition mutually.
Described chassis is connected with underseal, and chassis diameter is greater than the diameter of cylinder, is less than the diameter of projectile tail opening.
Described jump ring mates equipped with chassis, be stuck on T-shaped groove, and protrude from outside body.
Described cylinder is provided with 2 apertures, and object is to allow the flame of the fire in a stove before fuel is added can touch the propellant powder in body cavity, and the position that it does not specify and shape, as long as can allow the fire in a stove before fuel is added propellant powder that ignites.
Described cylinder is cylinder or positive gengon, as equilateral triangle body, square or regular pentagon body etc.
Described underseal is provided with impression along the edge of cylinder, and is outwards provided with many ray impressions that angle is identical taking body axle as the center of circle, dark outer shallow in impression.If the object of impression is to reduce the thickness at underseal setting regions place.In the time that propellant powder breaks out, impression place is exactly place the weakest on underseal, and the gas that propellant powder produces will be from tearing underseal here.Effect is similar to the impression of pop can opening part.
When transmitting, light after propellant powder when the fire in a stove before fuel is added, propellant powder promotes chassis to projectile tail, and chassis drives jump ring inwardly to shrink, and bullet is launched smoothly.
The utility model has replaced the fixed root edge of original bullet with the movable root edge of chassis and jump ring composition.When manufacture, only need movable root edge to protrude from beyond body, similar full root edge formula, guarantee extractor can be held, and the groove at projectile tail place can optionally make suitable amendment, then constriction bore is to caseless cartridge diameter.
The utility model caseless cartridge does not have regular length, caliber and bullet type, and user can manufacture or transform existing have shell bullet and firearms according to actual needs.In actual applications, such as bore is the bullets such as 5.6MM, 5.8MM, 7.62MM, the bullet of same bore also can be because purposes difference has different length, with the utility model can being applied to per family to any bore, random length, arbitrarily in the transformation that has shell bullet of bullet type, but the length of caseless cartridge after transformation should not exceed the length of original shell bullet.Reason is: the ejection hole of existing firearms must ensure that the supporting shell case that has shell bullet can normally dish out.The design in firearms ejection hole is not being made under the prerequisite of any amendment, if caseless cartridge is failed normal transmission, also can normally dished out via ejection hole.
The utility model has the advantages that: the fire in a stove before fuel is added and propellant powder have been realized to sealing, both reached with existing and had the same storage security of shell bullet, stability high, also avoided the spontaneous combustion of propellant powder; The normal use that movable root edge ensures bullet on caseless cartridge, moves back thorax is set.By built-in propellant powder with movable root edge is set, the utility model caseless cartridge is more existing shell bullet volume-diminished, can do less change to existing firearms, cannon, and compatible existing firearms to greatest extent, save a large amount of designs and recondition expense.
