Detachable chain accommodating device for 7.62 mm assault general-purpose machine gun

The present invention relates to weapon systems, and more particularly to a detachable chain accommodator for a 7.62 mm assault general purpose machine gun.

In order to improve the launch speed of traditional firearms, various countries have developed a number of automatic firearms capable of bursting shots in the mid-19th century to the beginning of the 20th century, including the Mitrailleuse hand cranked machine gun designed by the Belgian merchants. The machine gun designer Gatling designed the Green machine gun and the Marker machine gun designed by Hiram Maxim and the world's first fully automatic shot in the rear of the barrel. These automatic firearms, because of their ability to perform continuous shooting, can be zoned with strong firepower, prevent enemy operations, or kill infantrymen trying to break out of the blockade area, and quickly become the weapon of the world’s military forces. However, these automatic gun designs are often large and cumbersome, lacking maneuverability, and can only be used to fire in positioning or defensive warfare.

Then, the machine gun, a very promising "infantry nemesis", began to experiment with the First World War and the Second World War. At this time, the machine gun still occupied the dominant position of the war. People quickly found that the machine gun can provide effective fire support for the infantry in addition to most static defense tasks. If the design of a lightweight machine gun can even follow the infantry's combat formation and exert immediate and powerful firepower, this is the beginning of the concept development of the SAW (Squad Automatic Weapon). However, most machine guns are still limited by weight restrictions and cannot meet the mission requirements of mechanized infantry mobile operations that flourished during the Second World War. Therefore, after the war, countries began to pay attention to reducing the weight of machine guns. The design concept of "lightweight and human gun machine guns" was born in this context.

With the difference between the different tactical use of machine guns in war and the design concepts of various countries, the development of machine guns has gradually enriched and diversified. In general, today's machine guns can be classified into three categories: light machine guns, heavy machine guns, and general machine guns. Light Mechanic Gun (LMG) is mainly a light machine gun that can be used for individual operations and carrying movements. It is usually light in weight, highly maneuverable, and easy to carry by individual soldiers. It can provide immediate support for infantry. The more famous ones are the Belgian FN Minimi machine gun, the German HK MG43 machine gun, etc. The heavy machine gun (HMG) mainly refers to the heavy machine gun that can provide powerful combat firepower at a long distance. It is usually installed on combat vehicles or heavy-duty tripods. Independently carrying sports, and using larger caliber ammunition, more famous are the United States White Langing 12.7mm M2 heavy machine gun, the former Soviet Union DShK heavy machine gun, etc.; General Machine Gun (GPMG) is used to perform a variety of combat missions. Universal machine guns, penetration ability Canon easily destroys or penetrates light vehicles and other semi-rigid targets. In addition to providing support for infantry classes, it can also be installed in vehicles or armor, fixed in fortifications, more famous are the US M60 machine guns, Belgium FN MAG machine guns, the former Soviet Union's PK and PKM machine guns.

These machine guns use a chain instead of a magazine. In existing equipment, the chain is usually carried in a hard bullet box or in a soft bullet bag. When shooting, place the bullet box on the ground beside the machine gun, then pull out the elastic chain in the bullet box and install it in the chassis to shoot.

In the use of the aforementioned bullet box, there are the following problems:

1. The procedure for installing the chain is complicated and time consuming.

2. When shooting, place the bullet box on the ground beside the machine gun. If the ground is uneven, it is likely to cause the bullet box to turn over and affect the shooting.

3. The bullet box is too far away from the chassis of the machine gun, so that the long part of the chain is in a state of being suspended and unsupported, which also affects the shooting. Therefore, sometimes another person is required to hold the chain to avoid the occurrence of a bullet when the chain is unsupported during shooting.

If you need to carry a machine gun, you need to hold the machine gun in one hand and the other hand in the bullet box, which is very inconvenient.

SUMMARY OF THE INVENTION The main object of the present invention is to provide a detachable chain accommodating device for a 7.62 mm assault general-purpose machine gun, which can be used to quickly replace a chain of a general-purpose machine gun.
