Offensive and defensive dual-purpose hand grenade and use method
PendingCN120063062AHand grenades
The invention discloses an offensive and defensive dual-purpose hand grenade and a using method, and belongs to the technical field of hand grenades. The device comprises a fragment sleeve, a bomb body and a detonating mechanism. Wherein the elastic body is arranged in the fragment sleeve in a sliding manner, but is not separated from the sleeve body; the detonating mechanism comprises an ignition assembly arranged in the fragment sleeve and a detonator arranged in the bomb body shell. Wherein the detonator is connected with the ignition assembly through a blasting fuse. When defense combat is carried out, the explosive in the shell of the bomb body is directly detonated through the detonating mechanism; at the moment, the projectile body is located in the fragment sleeve; during explosion, a large number of fragments are accompanied by shock waves generated by explosion. When an attack combat is carried out, the projectile body is pulled out of the fragment sleeve; at the moment, the projectile body is located outside the fragment sleeve; during explosion, a large number of fragments are not generated, and impact waves generated by explosion cause harm to enemies; and meanwhile, the fragment sleeve is equivalent to an extended grab handle of the projectile body, so that the throwing distance can be increased.

A safe anti-personnel grenade with a quasi-spherical fuse and integrated structure
ActiveCN116147433BImprove reliabilityImprove ignition reliabilityHand grenadesBlasting cartridgesDetonatorDetonation
This invention discloses a safe fragmentation grenade with a quasi-spherical integrated detonation and warhead structure, consisting of a fragmentation warhead and a safe delayed-detonation fuse arranged along the warhead's axis. The fragmentation warhead includes a lower body, an upper body, a lower explosive ring, and an upper explosive ring. The safe delayed-detonation fuse is a delayed-detonation fuse with spatial explosion-proof, redundant safety, and explosive handling characteristics, including a detonator base, a flame detonator, a support tube, an impact delay cap, a firing pin, a firing spring, a detonating charge, a sleeve, a pull pin, a pull ring, a safety ball, and a nut. The upper and lower bodies are also the main structural components of the fuse. The integrated detonation and warhead structure is not a simple stacked structure, resulting in a small size and light weight. The nut encloses the pull pin and pull ring, replacing the traditional grip, resulting in a smooth surface and good safety during service and tactical maneuvers. With an outer contour close to a sphere and a center of mass located at the center, its air resistance characteristics are independent of flight attitude, ensuring a stable trajectory, controllable impact point, and long throwing distance.

Oval kinetic grenade with multiple non-lethal impact effects
The invention discloses an oval kinetic energy hand grenade with multiple non-lethal strike effects, comprising a safety component, an ignition component, a separation component, a projectile component, a detonation component and a load component. The separation component is used to realize the ejection of the ignition component to avoid the hard firing seat from accidentally injuring a target. The projectile component has a built-in detonation component and a load component. The load component comprises OC stimulation powder, a marking ball and a rubber ball. The detonation component has a built-in two-stage detonation mechanism, which realizes the emission of the marking ball through a primary explosion, and realizes the rupture of the projectile, the lasing of projectile fragments and rubber balls, and the rapid spraying of OC stimulation powder through a secondary explosion. By designing a prefabricated crack groove, the projectile ball wall explodes to form a uniform kinetic energy injury element without sharp edges. With the addition of the rubber ball, a double kinetic energy strike on a group target is realized, and two explosion sounds are emitted successively, which has the multiple non-lethal strike effects of detonation deterrence, dyeing marking, double kinetic energy strike and stimulation and dispersal.

The grenade may include a head section with a triggering mechanism, and a modular hollow core with a rod having an upward mechanical bias towards the head section, which may include a safety pin, lever, and pivot. When the pin is pulled, a lever can be released after timed delay, and the release of the lever allows the rod to advance upward, which triggers strike pins that strike a primer which ignites a propellent that ejects a carpel segment from the core. The propellent simultaneously ignites a fuse in the body of the carpel segment, and the fuse triggers a detonation of the main charge in the carpel. Timed delays on the fuse can be used to cause the carpel segments to detonate at different times.
