Problems solved by technology

However, it is necessary to add a set of air guide tube, piston connecting rod and other mechanisms to drive the automatic machine, which increases the weight, and the structure is difficult to simplify, such as 81-, 56C, etc.

Embodiment Construction

[0030] When the gun is pushed, it is held up by the drooping V-shaped clamping iron control end and cannot move forward, so that the gun is not in a safe state ( Figure 5 ).

[0031] When the trigger lever is pulled and the safety state is released, the bolt is pushed into the air-controlled bolt lock ( figure 1 ), and buckle with the V-shaped clamp iron control end along the V-shaped control surface. At this time, the bolt is pushed into place, and the firing pin protrudes to fire the bullet ( figure 2 ).

[0032] When the gunpowder gas pushes the warhead over the piston hole at the rear of the barrel, the gas force exerts a pressure on the control arm through the gas force piston in the piston hole, so that the V-shaped clamp iron control end buckles the bolt along the V-shaped control surface to form a lock ( image 3 ).

[0033] When the warhead is pushed out of the barrel, the pressure in the barrel decreases, the force of the gas-bearing piston on the V-shaped clam...

Abstract

The invention provides a novel rifle bolt mechanism. With gunpowder combustion gas as power, a core device (a pneumatic control rifle bolt lock) locks a rifle bolt thrusting into along the V-type control surface with the help of a lever reverse fastening device, and the larger is the combustion gas power, the larger is the reverse fastening power. When the combustion gas power is reduced to a preset value, the rifle bolt can be thrust aside by recoil of a bullet, so that the actions of unlocking, shelling and rifle bolt resetting are finished. The rifle bolt mechanism further has the functions of non-in-place safety and percussion control and is particularly suitable for a rifle of a bullpup structure. The purpose is to simplify an existing rifle bolt structure, and many structural contradiction problems, existing in the process of the light-weight trend and generalization, of rifles in the contemporary era are solved.

Description

Technical field: [0001] The invention provides a new air-controlled bolt mechanism, which is characterized by simple structure and reliable locking, and is especially suitable for rifles with bullpup structure. Background technique: [0002] There are many structural contradictions in the process of lightweight and universal design of contemporary rifles. [0003] The structure of the free bolt type weapon is simple, but there are problems such as large mass of the transmitter, poor shooting accuracy, inability to lock reliably, and inability to launch high-power ammunition. At present, it is mostly limited to submachine guns that use pistol bullets, such as Type 85. [0004] The air-guiding structure is reliable in locking, high in shooting accuracy, and capable of firing high-power rifle bullets. However, it is necessary to add a set of mechanisms such as air guide tube and piston connecting rod to promote the automatic machine, which increases the weight, and the struct...
