Description

Adjustable magazine interface

Technical Field

The invention relates to the field of automatic weapon disciplines, in particular to an adjustable magazine interface.

Background

Since the advent of firearms, firearms and ammunition have high compatibility, the size of the bullet fired by each type of firearms tends to be the same, and the adaptability of the firearms to the ammunition is severely limited. With the development of automatic weapon technology, firearms are required to meet different environmental and tactical requirements, the adaptability of firearms to ammunition is continuously expanded, wherein the expansion of ammunition with different length launched by firearms is one of the directions for increasing the adaptability, and in this respect, the use of representative weapons with larger ammunition length difference is an amphibious rifle which is researched and developed by various countries at present.

The underwater rifle is used as a special automatic weapon, is a weapon designed for underwater use, goes through the development process from a special underwater bullet weapon to two kinds of ammunitions for one gun, and is an amphibious rifle which can be used underwater or on land and is researched and developed from the development dynamics of various countries at the present stage, so that the underwater rifle is the main development direction of the underwater rifle in the future. The firing of two ammunitions flying in media of different density (air or water) with one gun brings great difficulties to the design of firearms; the common ammunition used in the air environment is a conventional ammunition, the ammunition used in the underwater environment is arrow-shaped, the difference between the ammunition magazines and the ammunition magazine is large (the length of the underwater ammunition is about 2 times of the length of the conventional ammunition), no gun in international standard weapons meets the successful application cases of different ammunition magazines, and the amphibious rifle is still in a state of technical blank.

Disclosure of Invention

The invention provides an adjustable magazine interface, which realizes that a firearm uses ammunition with different lengths by designing a magazine base with adjustable position and selecting a magazine interface scheme according to the type of the ammunition.

The invention comprises a magazine, a magazine base, a magazine catch, a conversion button and a magazine spring, and adopts the technical scheme that: the bottom of the magazine is provided with a magazine hole, the front end of the magazine hole is provided with a magazine hanging step, two sides of the magazine hole are provided with long grooves for mounting magazine seats, and two ends of each long groove are respectively provided with a short magazine limiting hole and a long magazine limiting hole; the magazine base is hinged with the magazine catch, and magazine springs act between the magazine base and the magazine catch.

The technical scheme comprises the following steps: the upper end of the cartridge case seat is provided with a conversion button hole formed by combining a circular hole and a rectangle, the conversion button is shaped corresponding to the conversion button hole, a limiting surface is arranged at the guide block, a spring is arranged between the two conversion buttons, and after the cartridge case is installed, the guide block is clamped into the long groove.

The magazine is clamped on the magazine seat, and the switching buttons are pressed on two sides of the magazine seat simultaneously, so that switching from the long magazine limiting hole to the short magazine limiting hole is realized.

The invention has the advantages that: the scheme that the firearm uses two kinds of ammunition with different lengths simultaneously is provided, the ammunition is switched between different positions on the magazine through the magazine base, the adaptability of the firearm to ammunition with large length difference is obviously improved, and the development of the underwater firearm towards an amphibious firearm is powerfully promoted.

Detailed Description

The present invention is described in detail below with reference to the attached drawings.

Fig. 1, 2, 3, 4 show: the bottom of the magazine 1 is provided with a magazine hole 11, the front end of the magazine hole 11 is provided with a magazine hanging step 12, two sides of the magazine hanging step are provided with long grooves 13 for mounting the magazine base 2, and two ends of each long groove 13 are respectively provided with a short magazine limiting hole 14 and a long magazine limiting hole 15; the magazine base 2 is hinged with the magazine catch 3, and magazine springs 5 act between the magazine base and the magazine catch. The upper end of the magazine base 2 is provided with a conversion button hole 9 formed by combining a circular hole and a rectangle, the shape of the conversion button 4 corresponds to the conversion button hole 9, a limiting surface 16 is arranged at the position of the guide block 10, a spring 6 is arranged between the two conversion buttons 4, and after the magazine base 1 is installed, the guide block 10 is clamped into the long groove 13. The magazine catch 3 is arranged on the magazine base 2, and the two sides of the magazine catch simultaneously press the conversion buttons 4, so that switching from the long magazine limiting hole 15 to the short magazine limiting hole 14 is realized.
