Problems solved by technology
[0002] Bullpup rifles have always been plagued by problems such as gunpowder smoke choking the nose, affecting sight and being unusable by left-handers due to the ejection position being close to the cheek when the traditional design is used.
Although there are many kinds of bullpup rifles with front ejection design in the world at present, none of them can completely push out the cartridge case at one time like traditional rifles, but use the action of the bolt to push the cartridge case into the ejection barrel first. , and then rely on the secondary shell to squeeze out the previous shell stuck in the barrel. If a dud is encountered during continuous shooting, there will be a danger of high temperature explosion due to the dud staying in the barrel when it is removed.
There are still many structural contradictions such as complex structure and poor reliability, such as the Belgian FN2000 assault rifle, etc.
[0003] At present, my country's bullpup rifles still use the traditional ejection design, and there is no practical front ejection scheme

Embodiment Construction
[0021] When the trigger handle is pulled by hand or the gas in the air duct is pushed, the piston rod and the ejection cylinder withstand the bolt and move back, while the ejection cylinder is exposed to the shell inlet.
[0022] The plate-shaped shell grabbing hooks installed symmetrically on both sides of the bolt pull out the shell casings. After the U-shaped lever meets the lever resistance iron, the shell end of the U-shaped lever is turned upwards, and the shell casings are pushed into the shell inlet of the ejection barrel. The bolt goes over After the trigger controls the sear, continue to retreat until the bolt is triggered and the bolt is locked. The shell ejection barrel starts to reset and eject the shell under the action of the return spring. state. After the ejection cylinder stops, the cartridge case moves forward according to inertia, and is ejected sideways after encountering an inclined plane.

The invention provides an elastic turning case-ejecting mechanism designed specially for an air-guide butt-free structure rifle. The elastic turning case-ejecting mechanism comprises an air-guide piston, a case-ejecting tube, a reset spring, a U-type deflector rod, a deflector rod sear, a bolt distance limiting gib and the like. The principle of the elastic turning case-ejecting mechanism is that the characteristic that a bolt is driven to retreat as gas in an air guide pipe pushes a piston rod, and can be reset automatically is adopted, and the specially-designed case-ejecting tube is mounted at the rear of the piston rod and is mutually matched with other accessories, so that turning case ejecting can be realized under single-shooting and continuous-shooting states. The invention aims to provide a practical and reliable turning case-ejecting scheme for the butt-free structure rifle and solve the problem of structural contradictions in the case-ejecting design of the butt-free rifle.
Description
Technical field: [0001] The invention provides an elastic direction-changing shell ejection mechanism specially designed for the air-guiding type bullpup-less structure rifle. Background technique: [0002] Bullpup rifles have always been troubled by problems such as gunpowder smoke choking the nose, affecting sight, and being unusable by left-handers due to the proximity of the ejection position to the cheek when the traditional design is used. Although there are many kinds of bullpup rifles with front ejection design in the world at present, none of them can completely push out the cartridge case at one time like traditional rifles, but use the action of the bolt to push the cartridge case into the ejection barrel first. , and then rely on the second round to squeeze out the previous round of the case that is stuck in the barrel. If a dud is encountered during continuous shooting, there will be a danger of high temperature explosion due to the dud staying in the barrel whe...
