Description

Gun-type launcher using a caseless cartridge

The present invention relates to a firing device for weapons and ammunition, and more particularly, relates to a gun-type firing device using an ammunition without a cartridge case.

Existing weapon launching devices mainly use propellant or gunpowder as fuel. After the propellant or gunpowder burns, high-pressure gas is generated in the chamber to push the warhead or projectile out. Existing this weapon launcher also has defect.

The existing bullet or cannonball launcher has a complex structure and is inconvenient to maintain. For example, the conventional launch tube has rifling (also known as Rifling) inside, which is used to make the conventional bullet rotate along the longitudinal axis of the rifling when it is fired, so as to produce a gyroscopic effect to stabilize the ballistic trajectory, and then shoot to the target more accurately.

However, the rifling grooves in the barrel are easy to accumulate sand, which may cause the bullet to jam and cause the barrel to explode.

In addition, the magazines of firearms have a small amount of ammunition storage, and the shell casings occupy a large amount of clip space. Existing bullets or shells all have bullet casings made of precious metals, which will consume a large amount of precious metals and cause a great economic burden. .

One object of the present invention is to provide a gun-type launching device using a caseless projectile, and the barrel of the gun-type launching device does not have rifling.

The guide groove 1332 is located on the inner wall of the chamber area 133 at the other end of the gun barrel 13. The number of the guide groove 1332 is the same as that of the projection 1211. In this embodiment, 4 guide grooves are used as an example. When the gun When the end of the machine handle 121 is pushed into the chamber area 133, the protrusion 1211 and the guide groove 1332 are matched with each other. In a preferred embodiment, the guide groove 1332 is an L-shaped corner guide groove , but not limited thereto, so that the bolt 12 locks and closes the chamber area 133 at one end of the gun barrel 13 to prevent the recoil force generated after firing the cartridge body 2 without a case.

The bolt handle 121 further includes an airflow groove 1212, the airflow groove 1212 surrounds the outer surface of the bolt handle 121, and abuts against the protrusion 1211, in this preferred embodiment, the airflow The groove 1212 has a second width W2 and a depth D (as shown in FIG. 4 ), and both the second width W2 and the depth D are 2 millimeters (mm), but not limited thereto.

When the percussion seat 22 is fired and the gunpowder in the caseless projectile 2 is ignited, the burned gas flows back to the airflow groove 1212 to prevent the gunpowder airflow from impacting backward.

In addition, the chamber area 133 further includes a convex body 1333, which is located on the inner wall of a necking area 1334 of the chamber area 133. It is connected with the groove 23 and pushes the cartridge without case 2 into the chamber area 133. When the bullet hook 122 hits the convex body 1333, the bullet hook 122 is released from the groove 23 , at the same time, the end of the bolt handle 121 is made to abut against the impact seat 22, and the caseless body 2 is pushed into the chamber area 133 by the bolt handle 121, and a firing pin of the bolt 12 123 collides with the impact seat 22, so that the shellless projectile 2 is ejected from the gun barrel 13 from the muzzle area 131.

In the above, when the impact seat 22 abuts against one side of the bolt handle 121, and the ejection hook 122 is connected to the groove 23, the bullet without the case 2 and the bolt handle 121 Simultaneously, the linear displacement movement 9 is carried out so that the empty cartridge body 2 moves out of the barrel 13 .

Please refer to Fig. 6 additionally. In addition, in another embodiment, the gun-type launching device 1 using a cartridgeless projectile further includes a fixing frame 14, which is arranged on the other side of the main body 11, and the The fixed frame 14 can stand on a plane, which increases the stability of the gun-type launcher 1 that uses the shellless projectile.
