摘要：【中文】本发明涉及枪械击发机构，一种惯性击针式击发机构，包括枪机、击针、击针拨盘、击针簧、驱动套、复位簧和阻铁。本发明通过驱动套带动击针拨盘及击针压缩击针簧储能，储能完成后，可通过继续压缩驱动套或者拨动击针拨盘的方式释放击针，击针拨盘与击针在击针簧作用下向前运动，击针拨盘停止在枪机定位面后，击针运动惯性继续压缩回针簧，最后撞击弹药底火实现击发。击发完成后，击针在回针簧作用下退入枪机内。本发明继承击针簧击针式击发机构良好精度的同时，实现击针只在击发瞬间处于击发状态，以适用于有此类要求的特殊武器；可应用于常规的非自动武器；可应用于采用开膛待击的自动武器；结构较为简单、紧凑，容易实现。 【EN】The invention relates to a firing mechanism of a firearm, in particular to an inertia firing pin type firing mechanism which comprises a firearm machine, a firing pin driving plate, a firing pin spring, a driving sleeve, a reset spring and a stop iron. The driving sleeve drives the firing pin drive plate and the firing pin to compress the firing pin spring for energy storage, after the energy storage is finished, the firing pin can be released by continuously compressing the driving sleeve or shifting the firing pin drive plate, the firing pin drive plate and the firing pin move forwards under the action of the firing pin spring, the firing pin drive plate stops behind the setting surface of the gun, the firing pin moves to continuously press and retract the firing pin spring by inertia, and finally the ammunition primer is impacted to realize firing. After the firing is finished, the firing pin retreats into the gun machine under the action of the needle returning spring. The invention inherits the good precision of the firing pin spring firing pin type firing mechanism, and simultaneously realizes that the firing pin is in the firing state only at the firing moment so as to be suitable for special weapons with the requirements; applicable to conventional non-automatic weapons; can be applied to automatic weapons that adopt open chamber to be hit; the structure is simple and compact, and is easy to realize.
