Description

一种自动***枪的辅助上弹机构
技术领域
本实用新型涉及***枪的上弹结构的技术领域,具体为一种自动***枪的辅助上弹结构。
背景技术
***枪上弹时,机匣与枪管弹膛之间设有斜向上的上弹引导斜槽,通过该上弹引导槽可以引导子弹进入枪管弹膛内,保证了弹匣内子弹准确入膛。如图1所示,上弹过程中,子弹2进入枪管弹膛1内部时,先与枪管弹膛1内部的枪机闭锁槽11的槽壁接触,然而由于该枪机闭锁槽11与枪管弹膛1之间存在台阶,因而上弹时,子弹2上端边缘处易与该台阶发生磕碰,从而引起卡弹危险。
实用新型内容
针对现有的***枪上弹时,子弹与枪机闭锁槽的槽壁会发生磕碰,从而引起卡弹的危险的问题,本实用新型提供了一种自动***枪的辅助上弹结构,其可以避免子弹与枪机闭锁槽的槽壁发生磕碰,降低卡弹的概率,实用性强。
其技术方案是这样的:一种自动***枪的辅助上弹机构,其包括枪管弹膛,所述枪管弹膛外部套装有节套,所述枪管弹膛内部靠近所述节套一端内部设有枪机闭锁槽,其特征在于:所述枪机闭锁槽内部设有固定连接的节套衬铁,所述节套衬铁的下端面靠近所述枪管弹膛的外侧一端还设有导向倒角。
其进一步特征在于:所述节套衬铁的外端面呈与所述枪机闭锁槽的部分槽壁相配合的弧形,定位销贯穿所述节套与所述节套衬铁固定连接。
采用了上述结构后,通过枪机闭锁槽内部设置的节套衬铁,从而使得子弹在上膛时,子弹的上端边缘处顺次通过节套衬铁外部的导向倒角及缓冲平面进入枪管弹膛内部,从而避免了子弹与枪机闭锁槽的台阶处磕碰,降低卡弹概率,实用性强。
附图说明
图1为现有技术结构的剖视图;
图2为本实用新型的剖视图;
图3为本实用新型图2中的A处结构放大图;
图4为本实用新型的节套衬铁的主视截面图;
图中:1、枪管弹膛;11、枪机闭锁槽;2、子弹;3、节套;4、节套衬铁;5、定位销。
具体实施方式
如图2至图4所示,一种自动***枪的辅助上弹机构,包括枪管弹膛1,枪管弹膛1的一端外部套装有节套3,枪管弹膛1内部靠近节套3一端内部设有枪机闭锁槽11,枪机闭锁槽11内部设有固定连接的节套衬铁4,该节套衬铁4设于枪机闭锁槽11的顶部,且节套衬铁4的外端面呈与枪机闭锁槽11的部分槽壁相配合的弧形,同时避开了枪机闭锁槽11内部的闭锁点,通过贯穿节套3的定位销5与节套衬铁4的上端固定连接,节套衬铁4的下端面靠近枪管弹膛1的外侧一端还设有导向倒角41。子弹2上膛时,子弹2先经上弹引导槽(图中未示出)进入枪管弹膛2的内部,子弹2的上端边缘处顺次经过节套衬铁4下端的导向倒角41及平缓处缓冲平面进入枪管弹膛1的内部,有效避免了子弹2与枪机闭锁槽11处的台阶处磕碰,降低卡弹概率,实用性强。
以上,仅为本实用新型较佳的具体实施方式,但本实用新型的保护范围并不局限于此,任何熟悉该技术的人在本实用新型所揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本实用新型的保护范围之内。因此,本实用新型的保护范围应该以权利要求的保护范围为准。
