[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] This embodiment provides a carbon fiber-wrapped metal powder emitter, such as Figure 1-Figure 3 As shown, the projectile includes a warhead as a direct damage striking mechanism for breaking the door lock, and the warhead includes a carbon fiber enclosure 8 containing a closed cavity, and a metal powder body 7 arranged in the closed cavity of the carbon fiber enclosure 8, and the metal powder body 7 fills the closed cavity of the carbon fiber enclosure 8; the metal powder body 7 is a gel of metal powder and paraffin.

[0030] This embodiment uses a carbon fiber envelope to seal and wrap the metal powder body. On the one hand, it can prevent the metal powder body from being dismembered or broken in the cartridge case and leaking into the gas holes or remaining in the barrel. On the other hand, it can prevent the metal powder body from chemically reacting when in contact with the air, thereby extending the shelf life of the bullet.

[0031] In addition, the metal powder body of the present embodiment is a gel body of metal powder and paraffin. The metal powder body breaks up quickly after hitting the door lock and is not prone to rebound, thus posing no threat to the shooter's personal safety.

[0032] In some embodiments, Figure 3 As shown, a layer of skeleton 6 for supporting the metal powder body 7 is provided on the periphery of the metal powder body 7, and the skeleton 6 is an integrally formed skeleton.

[0033] Specifically, the skeleton 6 is placed in a casting mold, and the mixed metal powder and paraffin melt are poured into the mold to obtain a metal powder body 7 wrapped with the skeleton 6 .

[0034] Specifically, the skeleton 6 is made of low-density polyethylene.

[0035] In this embodiment, a layer of skeleton 6 is added between the carbon fiber envelope 8 and the metal powder body 7 to ensure that the carbon fiber envelope 8 will quickly separate from the metal powder body 7 and fall to the ground after hitting the door lock, and will not pose a threat to the shooter's personal safety.

[0036] In some embodiments, the projectile further comprises a cup holder 5 with one end open and the other end closed, the bullet is disposed in the cavity of the cup holder 5, and the bullet fills the cavity of the cup holder 5. Figure 5 As shown;

[0037] like Figure 2 As shown, the side wall of the cup holder 5 is provided with a plurality of axially symmetrical grooves that penetrate the side wall of the cup holder 5, so that the cup holder can be quickly separated from the bullet after being ejected from the muzzle to avoid hurting the shooter; one end of the groove is spaced a first preset distance from the closed end of the cup holder 5, and the other end of the groove extends to the open end of the cup holder 5.

[0038] Specifically, the cup holder 5 is made of bright resin or low-density polyethylene.

[0039] This embodiment uses a cup holder to perform secondary sealing and wrapping of the metal powder body, so that the metal powder body can withstand direct scraping by the barrel rifling and the gas holes, so as to further prevent the metal powder body from being dismembered or broken in the cartridge case and leaking into the gas holes or remaining in the barrel, thereby effectively avoiding malfunction of the firearm.

[0040] In some embodiments, the launcher further includes a base 4 with a hollow interior, a rectangular thin-walled annular airtight tail wing is provided at the tail of the base 4, and the front end face of the base 4 is in contact with the rear end face of the cup holder 5.

[0041] Preferably, the base 4 and the rectangular thin-walled annular air-sealing tail wing are integrally injection-molded using low-density polyethylene to enhance their structural stability.

[0042] In some embodiments, the projectile further comprises a cartridge case 3, the bullet head, the cup holder 5 and the base holder 4 are coaxially arranged in the cavity of the cartridge case 3, and the tail end face of the base holder 4 is spaced apart from the tail end face of the cavity of the cartridge case 3 by a second preset distance to form a storage cavity;

[0043] The storage cavity is used for placing the propellant 2.

[0044] Preferably, the propellant 2 is placed at the bottom of the cavity of the cartridge case 3 .

[0045] In some embodiments, Figure 4 As shown, a step is provided in the cavity of the cartridge case 3 along the inner circumferential surface of the cartridge case 3 for limiting the base 4 .

[0046] Preferably, the base support 4 is press-fitted onto the step of the cartridge case 3 to prevent the base support 4 from axially moving toward the rear end surface of the cartridge case 3 .

[0047] Specifically, the outer circumference of the base 4 is tightly fitted with the inner circumference of the shell.

[0048] In some embodiments, the projectile further includes a primer 1, and the primer 1 is disposed in a groove opened at the rear end of the cartridge case 3;

[0049] The primer 1 and the cartridge case 3 are coaxially arranged.

[0050] Preferably, the primer 1 is press-fitted into a groove formed at the rear end of the cartridge case 3, and the outer plane of the primer 1 is arranged so as to protrude from the outer plane of the cartridge case.

[0051] Specifically, the primer 1 is press-fitted into a groove formed at the rear end of the cartridge case 3 and then coated with sealant.

[0052] In some embodiments, a fire transfer hole is also provided at the rear end of the cartridge case 3 .

[0053] In some embodiments, there are multiple fire transfer holes, and the multiple fire transfer holes are symmetrical around the central axis of the shell 3.

[0054] In some embodiments, the projectile further includes a sealing piece 9 , and the sealing piece 9 is arranged at the head of the cartridge case 3 .

[0055] Specifically, the head of the cartridge case is curled inwardly and pressed onto the sealing sheet 9, and the primer 1, the propellant 2, the base 4, the cup 5 and the bullet are encapsulated in the cartridge case 3 to form a projectile.

[0056] The working process and principle of the carbon fiber-wrapped metal powder emitter of the present invention are as follows:

[0057] The explosion-proof gun equipped with the projectile of the present invention is placed close to the door lock, and the firing pin hits the primer 1 to ignite the gunpowder in the primer 1, and further ignites the propellant 2 through the fire transmission hole. The gunpowder gas generated by the combustion of the propellant 2 expands and pushes the base 4, the cup 5, the warhead (composed of the skeleton 6, the metal powder body 7 and the carbon fiber envelope 8) and the sealing piece 9 to move forward to the shell ( Figure 1 The sealing piece 9 quickly falls off at the muzzle, while the base 4, cup holder 5 and bullet jointly damage and strike the door lock; because the base 4, cup holder 5 and frame 6 are made of plastic and fragile materials, they quickly break after hitting the door lock and will not pose a threat to the shooter's personal safety; the metal powder and paraffin gel body (i.e., the metal powder body 7) also quickly break after hitting the door lock and are not likely to rebound, so they will not pose a threat to the shooter's personal safety; the carbon fiber envelope 8 will quickly fall off after hitting the door lock and is not likely to rebound, so it will not pose a threat to the shooter's personal safety; therefore, the projectile (ammunition) of this embodiment has higher safety.

[0058] In summary, the solution proposed by the present invention has the following technical effects:

[0059] On the one hand, the present invention uses a carbon fiber envelope to seal and wrap the metal powder body to prevent the metal powder body from being dismembered or broken in the cartridge case and leaking into the gas holes or remaining in the barrel; on the other hand, the metal powder body of the present invention is a conglomerate of metal powder and paraffin. The metal powder body quickly breaks apart after hitting the door lock and is not prone to rebound, thus posing no threat to the shooter's personal safety.
