Description
Technical Field
The invention belongs to the technical field of light weapons, and relates to a novel compartment type 35 grenade box mechanism with assistance and guiding functions.
Background
The 35 grenade launcher is a common curved-fire weapon used in weapon stations, and the reliability of ammunition feeding is a very important issue when shooting. Two main factors mainly influence the reliability of ammunition supply and delivery, namely, an ammunition placing structure and the dragging elasticity. In addition, the appearance structure of the magazine is an important reason for influencing the integrated design of the weapon station.
Traditional 35 grenade case appearance is cylindric, and the ammunition is stacked through the bullet chain, layer upon layer winding, places the axis of rotation at the circle center. After the front-end ammunition enters the bore, the follow-up ammunition and the rotating shaft are dragged to rotate, and other ammunitions move into the grenade launcher in sequence. The remote control weapon station has small size, compact arrangement of components on the station, more occupied space of the cylindrical magazine and low matching integration level on the weapon station. The ammunition circles are in direct contact with each other, the friction force is large, and the clamping stagnation phenomenon is easy to occur. The traditional 35 grenade case does not have assist drive device, and the elasticity of dragging is great.
