Abstract

A plastic sleeve containing a tubular body with a flange and a bottom fixed to the body with a socket for a capsule, characterized in that the body and the bottom are made in one piece, and the inner surface of the bottom is made spherical.

Description

PLASTIC HOUSING

The utility model relates to ammunition, namely to plastic sleeves for cartridges (sport-hunting, signal, etc.) "

S famous gun cartridges use plastic sleeves of various designs.

Thus, a plastic prefabricated sleeve is known, comprising a tubular housing made of plastic, fixed with a paper wad on a metal base with a socket for a 2 J igniter capsule made in it. Its disadvantage is the complexity of the design.

Also known is a plastic prefabricated sleeve made of only plastic parts, and containing a cylindrical body with a flange and a bottom with an inner conical surface and a socket for the capsule | 2 j. A disadvantage of the known liner is reduced strength when) barely, ...

3 as a prototype, a plastic prefabricated sleeve containing a step-shaped tubular casing with a flange and „,

a composite bottom with an internal conical surface and a nest for a capsule Гз The well-known cartridge case is durable when fired, but it is complicated in construction and laborious in manufacturing.

,. , 1 1 I,

at the same time, with high strength when firing and increasing the internal balshstika of the shot.

The problem was solved by the monolithic execution of a ploto-mas sleeve, the tubular body with the flange of which is made integrally with the bottom, as well as the execution of the inner surface of the bottom is spherical.

Comparative analysis of the proposed sleeve on the prototype

and other decisions in the art shows that the set of features set forth in the patent formula is unknown from the existing level of technology, on the basis of which it can be done

a conclusion on the conformity of the proposed solution to the criterion of a novelty utility model. Correspondence to its other criterion of a utility model, industrial applicability is evident from the inadequate data. specific implementation example.

The utility model is illustrated by a drawing, which shows a General view of the proposed sleeve.

The plastic sleeve contains a tubular body I with a flange 2, made in one piece with DN 3, In the bottom 3 there is a socket 4 for capsules. The inner surface 5 of the bottom 3 is made spherical. To ensure the possibility of placing the powder gasket inside the tubular body I there is a ledge b, and

for easier removal of the fired sleeve from the barrel, longitudinal grooves 7 are made on the outer surface of the housing I.

Due to the spherical inner surface 5 of the bottom 3, the internal ballistics of the shot increases (due to a more efficient and uniform combustion of the powder) and a high strength shell during the shot is achieved (there are no stress concentrators). With all this, the proposed sleeve is extremely simple in design and technologically advanced to manufacture.
