Abstract
This utility model discloses a non-lethal low-damage fragmentation control structure, including a cartridge case. The cartridge case is a cylindrical tube with a sealed bottom and a triggering component at the top. Inside the cartridge case, from the inside out, are arranged a detonating charge, a main charge, and a support cylinder. A fuse is located at the top of the detonating charge, corresponding to the triggering component. The support cylinder is located between the inner wall of the cartridge case and the outer wall of the main charge, and has a buffer cavity. The buffer cavity is evenly distributed in a ring around the main charge. Pre-fracture protrusions are arranged on the outer circumference of the cartridge case, extending in a straight line parallel to the cartridge case axis. This utility model reduces the number and volume of product fragments through optimized cartridge case design, eliminating the lethal effect of cartridge case fragments. At the same time, the double-shell structure design forms an explosion buffer zone, reducing the detonation energy of the detonating charge and the main charge, thereby eliminating the harm to personnel from explosion residue.
