[0002] With the rapid development of intelligent and unmanned weapons and equipment, the requirements for the use and unmanned maintenance of weapons are becoming increasingly higher. Among them, barrel oiling is an indispensable part of the weapon's use and maintenance process, especially the barrel oiling maintenance after each live ammunition firing, which is an important guarantee for barrel corrosion prevention and life extension.

[0003] The inner bore of the barrel is mainly oiled manually by using a cotton cloth dipped in oil on a barrel cleaning rod or a cleaning rod to oil the inner bore of the barrel. The cleaning bullets for the domestic 961 No. 12 riot anti-gun and shotgun are manually immersed in oil before use, and then fired to achieve barrel oiling. Currently, these barrel oiling methods all require manual auxiliary operations, which are labor-intensive and have low cleaning efficiency. They cannot truly achieve unmanned control and cannot meet the requirements of unmanned, intelligent, and rapid response in modern warfare. Therefore, it is of great significance to develop barrel inner bore oiling equipment suitable for unmanned combat. Summary of the invention

[0004] In view of the shortcomings of the existing barrel inner bore oiling technology, such as the inability to fully realize unmanned operation and the inability to meet the requirements of use in harsh environmental conditions, the purpose of the present invention is to provide a new barrel inner bore oiling bullet that can be launched compatible with standard bullets and realize unmanned operation. At the same time, it can be used in various harsh environments to meet battlefield needs.

The front end of the bullet body is a solid structure, and the middle and rear part of the bullet body is a hollow structure. An elastic sleeve is fixedly installed in the middle of the bullet body. The diameter of the elastic sleeve is larger than the maximum diameter of the bullet body. The elastic sleeve has a plurality of through holes in the radial direction. The through holes are connected to the cavity in the bullet body. Lubricating oil is installed in the rear cavity of the bullet assembly. A sealing ring and an oil sealing film are arranged above the lubricating oil. A retaining ring is installed at the tail of the bullet body, and an ejector pin is arranged above the retaining ring.

[0008] The bullet body is made of hard material, and the elastic sleeve is made of rubber, latex or composite material.

[0009] The cartridge assembly and the bullet assembly are tightly matched.

[0010] The through holes on the elastic sleeve are evenly distributed.

[0011] The beneficial effects of the present invention are:

[0012] 1) The cartridge has the same shape as the existing standard cartridges, which enables compatible firing with standard cartridges and has good adaptability;

[0013] 2) The method of using gunpowder combustion to generate high-pressure gas is safe, reliable and mature in technology;

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] like Figure 1 As shown, a barrel inner bore oil-coated bullet is composed of a cartridge assembly 1 and a bullet assembly 2, and the cartridge assembly and the bullet assembly are tightly matched. Figure 2 , Figure 3 As shown, the cartridge assembly 1 consists of a cartridge 3, a primer 4, a propellant 5, a piston 6 and a sealing ring 7, wherein the primer 4 is located at the bottom of the cartridge 3; the appearance of the cartridge 3 and the primer 4 are completely consistent with the standard bullet to ensure compatible firing; a certain amount of propellant 5 is arranged at the bottom of the cartridge 3, and the propellant 5 adopts standard gunpowder of the standard bullet; a piston 6 is arranged at the front side of the propellant 5, and the piston 6 can slide forward along the axial direction of the cartridge 3; a sealing ring 7 is arranged between the piston 6 and the cartridge 3 to ensure the airtightness of the gas after the gunpowder is burned; a positioning surface a is arranged at the front of the cartridge 3, and the piston 6 can be stuck by the cartridge positioning surface a when it moves to the end point.

[0029] like Figure 2 , Figure 4 As shown, the bullet assembly 2 is composed of a bullet body 8, an elastic sleeve 9, a snap ring 10, a ejector pin 11, a sealing ring 12, lubricating oil 13 and an oil sealing film 14. Figure 6 As shown, the bullet body 8 is made of hard material and is the skeleton of the bullet assembly, providing support and guidance for other parts; the front end of the bullet body is a solid structure, the middle and rear part of the bullet body is a hollow structure, there are several through holes in the middle bullet body, and an elastic sleeve is fixed in the middle of the bullet body. The elastic sleeve 9 is rubber, latex or other composite materials with a certain elasticity. The diameter of the elastic sleeve is larger than the maximum diameter of the bullet body, and the diameter of the elastic sleeve is slightly larger than the inner diameter of the barrel, so that it can fit closely with the inner bore of the barrel and be wiped and oiled; as shown in FIG. Figure 7 As shown, the elastic sleeve has a plurality of through holes in the radial direction, and the through holes are connected to the cavity in the bullet body, and the through holes on the elastic sleeve are evenly distributed. The rear cavity of the bullet assembly is filled with lubricating oil 13, and there are sealing rings and oil sealing membranes above the lubricating oil. A retaining ring is installed at the tail of the bullet body, and there is a ejector pin above the retaining ring, as shown in FIG. Figure 5As shown, the ejector pin 11 is formed by connecting the rear plunger and the front needle. The sealing of the lubricating oil 13 is achieved under the action of the sealing ring 12, the oil seal film 14 and the plunger; the plunger is limited at the tail of the bullet body by the clamp ring 10; the plunger can move forward axially under the action of gas pressure, driving the front needle to pierce the oil seal film 14.

[0030] Before combat use, multiple oiled bullets can be loaded into one of the feed channels. During combat, when the barrel needs to be oiled, the oiled bullet channel is selected for feeding, and the barrel can be oiled once.

[0031] During use, after the oiled bullet enters the barrel chamber, the primer 4 is fired, and the propellant 5 is ignited by the primer, quickly generating high-pressure combustion gas. When the combustion gas pressure is greater than the preload of the piston 6, the sealing ring 7 and the inner wall of the cartridge case 3, the piston 6 moves forward rapidly under the action of the high-pressure gunpowder gas, compressing the air at the front end of the cartridge case 3 to generate a certain air pressure. The ejector pin 11 moves forward under the action of the air pressure and pierces the oil seal 14. The lubricating oil 13 is squeezed into the cavity in the middle of the bullet body 8 and flows out from the through hole of the elastic sleeve 9. At the same time, the bullet assembly 2 is squeezed out of the mouth of the cartridge assembly 1 and enters the barrel. In the process of the bullet assembly 2 passing through the inner bore of the barrel, the lubricating oil 13 continuously flows out from the small holes of the elastic sleeve to wipe and oil the inner bore of the barrel. The bullet assembly 2 after firing is as follows Figure 4 As shown, after the bullet assembly 2 flies out of the barrel, the internal gas pressure drops rapidly to the ambient pressure, and the piston 6 is held by the a surface of the cartridge 3 after moving to the front end of the cartridge 3 and does not continue to slide forward. Figure 3 As shown, the gunpowder gas and residue inside the cartridge are sealed, and no other impurities are generated inside the barrel, ensuring the integrity of the oil layer in the barrel.
