A piecewise type suppository, consisting of a head, a pin, a percussion barrel, a hair spring, and a bolt body. The pin is located inside the head of the machine. The percussion barrel is located inside the body of the gun. Its feature is that one end of the barrel is connected to a pin, the other end is set with a lock spiral surface, the rear end of the gun body is connected with a pulling handle and the rear of the gun body. The part also has an open lock helix surface which can bite each other on the firing tube; the content chamber of the percussion barrel holds the blow spring, the end of the hit spring is mounted on the bolt cap of the gun body; the steel connection of the rear part of the hair barrel has a iron blocking seat, the middle of the iron blocking seat is set with the iron hindrance clasp face, and the rear part is set to prevent the rotation of the hair cylinder. A protruding platform. The utility model adopts the design principle of two section compression spring. In the case of ensuring the total energy, the stiffness of the spring is reduced, thus the unlocking force is reduced greatly and the breakdown force is reduced indirectly. At the same time, a variety of safe and reliable design measures are adopted to improve the reliability and safety.

一种分段式栓动枪机
本技术涉及一种栓动枪机,尤其涉及一种分段式栓动枪机。
技术介绍
栓动式枪机已广泛运用于单发步枪和弹道枪方面,一般由闭锁机构、击发机构和抽、抛壳机构等组成,完成推弹入膛、闭锁、击发枪弹、开锁、抽壳和抛壳等功能。栓动式枪机一般存在如下不足:一是开锁力重,动作不够平顺;二是击发解脱力(扳机力)大;三是可靠性和安全性不够。
技术实现思路
本技术要解决的技术问题是克服现有技术的不足,提供一种具有开锁力和击发解脱力小、安全可靠的分段式栓动枪机。为解决上述技术问题,本技术提出的技术方案为:一种分段式栓动枪机,包括机头、击针、击发筒、击发簧和枪栓体,所述击针位于机头的内部,击发筒位于枪栓体的内部,所述击发筒的一端连接击针、另一端设置有开锁螺旋面,所述枪栓体的后端连接有拉机柄,枪栓体的后部还设置有与击发筒上能够相互咬合的开锁螺旋面;击发筒的内容腔容纳击发簧,击发簧的一端顶在枪栓体的枪栓帽上;所述击发筒的后部钢性连接有阻铁挂座,阻铁挂座中部设置有阻铁扣合斜面,后部设置有防止击发筒旋转的限位凸台。本技术的分段式栓动枪机,分两阶段压缩击发簧。第一阶段:开锁时,通过枪栓体和击发 ...
