Abstract
The invention discloses a safety protective cover for the primer falling of firearms ammunition, belonging to the field of ammunition. The invention can effectively avoid the safety problem caused by accidental triggering of primer and propellant charge when various accidental impacts such as falling, collision and the like occur to the cannonball or the propellant charge module (charge cartridge) thereof in the service processing process. When the cannonball leaves a factory, a shallow-pot-shaped falling safety protection cover is additionally arranged on the bottom surface of a cannonball of the cannonball to cover primer positioned at the center of the bottom surface of the cannonball, so that accidental falling collision cannot directly impact the primer to cause accidental ignition. Before shooting, the protective cover is removed, and the gun can be normally used. Similarly, a primer falling safety protection cover can be additionally arranged outside the bullet shell.
Description
Technical Field
The invention belongs to the field of ammunition, mainly relates to a cannonball, and particularly relates to a protective cover for protecting the falling of a primer of the ammunition of a gun.
Background
Projectiles typically comprise a projectile, a cartridge, a propellant charge within the cartridge, and a primer secured centrally to the bottom end of the cartridge. The primer contains sensitive initiating agent, and is stimulated to fire (impact primer) by inputting mechanical energy (such as impact) or electric energy (electric primer) for outputting flame to ignite propellant powder.
Even if the primer is electric, the inner charge of the primer is sensitive to electric energy stimulation and mechanical stimulation, and the mechanical strength of the input end of the primer is often insufficient, so that when the charge cartridge of the fixed-loading shell or the split-loading shell is accidentally dropped or impacted during service treatment, particularly when the primer is dropped downwards to a sharp hard object or the primer impacts the sharp hard object, the primer can be accidentally ignited, and the charge is ignited, so that safety accidents are caused. Such accidents occur at times. For example, a 25 mm caliber, fixed-bore projectile in a factory line experiences an accidental drop of primer from the work bench down to a sharp hard object resulting in an accidental fire from the primer igniting the propellant charge. To avoid such accidents, ammunition production and use requires extra care in handling and handling the primed cartridge and the loaded projectile to prevent loss of hands and fall. From an ergonomic point of view, accidents involving accidental falls due to ammunition handling and handling errors cannot be completely avoided due to the presence of human factors. Therefore, the structural protection of the primer of the cannonball is necessary.
Disclosure of Invention
In order to avoid the safety problem caused by accidental triggering of primer and propellant charge due to various accidental impacts such as falling, collision and the like of a cannonball or a propellant charge module (a charge cartridge) thereof in the service processing process, the invention provides a safety protection cover for falling of the primer of the gun ammunition.
The technical solution for realizing the invention is as follows: a protective cover for protecting the safety of the primer falling of the ammunition of a gun is installed at the bottom of an ammunition cartridge, wherein the protective cover is in a shallow spittoon shape, the mouth of the protective cover is in a closed shape, the inner diameter of the protective cover is slightly smaller than the outer diameter of the bottom edge of the ammunition cartridge, and the protective cover can be buckled on the outer surface of the bottom of the ammunition cartridge after proper pressure is applied. The material of the protective cover is plastic, in particular polytetrafluoroethylene.
Compared with the prior art, the invention has the remarkable advantages that: the bottom surface of the cartridge case of the cannonball is additionally provided with the falling safety protective cover, so that the cannonball plays roles of protection, buffering and shock absorption under the conditions of impact and the like, and the safety problem that the 'shell-explosion' accident of igniting and launching explosive charges, even the main explosive charges in the projectile or the warhead continue to be detonated, caused by accidental ignition of primer due to impact is effectively solved. Ammunition primer falls safe visor designs according to the existing cartridge case of matching, does not change existing cartridge case design for service processing and use protection, only excise before closing on the shooting.
Compared with the shell, the bullet is almost fixed-loading type, the whole bullet of the large-caliber bullet has larger mass, and the problem of primer falling safety is also outstanding. Similarly, a primer falling safety protection cover can be arranged outside the bullet shell.
