Machine gun transmitter

Technical Field

The invention relates to the technical field of firearms, in particular to a machine gun transmitter.

Background

The firing mechanism is a mechanism that controls the firing mechanism to fire or trigger to fire. The launching mechanism needs to ensure reliability and safety during design and can improve manufacturability on the basis.

The reliability means that a firing pin, a firing hammer or a gun bolt and a machine frame are firmly buckled at a position to be fired before firing, the firing pin, the firing hammer or the gun bolt and the machine frame are reliably released in time during firing, and the machine gun or the submachine gun which is in a cocked standby state is mainly released from the gun bolt or the machine frame; the safety mechanism can prevent early ignition and accidental ignition, and when the launching mechanism is arranged at a safety position, the launching mechanism is ensured not to be capable of implementing the percussion; the manufacturability refers to that each component part of the launching mechanism is convenient to process and assemble, and the improvement of the manufacturability needs to reduce the number of the mechanism parts as much as possible so as to facilitate assembly and prevent neglected assembly.

The present firearms structure's transmitter scheme is more, can both guarantee the reliability basically, but has more transmitter in the aspect of the security and has the potential safety hazard, if insurance/speed and slow machine be in the middle of two gears some transmitter can not the insurance, rotate speed and slow machine when withholding the trigger and strike scheduling problem by oneself. In addition, most of the existing transmitters have complex structures, more parts and components, complex production procedures and too many size elements required to be ensured in the assembly process.
