Description

TECHNICAL FIELD

[0001] The present application relates to the field of ammunition, in particular to a full-shaped blank cartridge which can be disintegrated after the bullet is discharged by using the launching energy. BACKGROUND

[0002] The blank cartridge refers to a bullet with only a shell, a small amount of charge and a primer, which is usually used for training and exercises and has a killing power at a short distance. There are two types of blank cartridges, one is a headless blank cartridge and the other is a head blank cartridge. The headless blank cartridge is composed of a metal shell, fast-burning launching charge and a primer. After the launching charge is loaded into the shell, a sealing plug or cap is added to the mouth, or the front end of the mouth is folded into a star-shaped cone and sealed with paint. When the headless blank cartridge is launched by an automatic firearm, it is difficult to quickly form sufficient chamber pressure due to the lack of bullet resistance, so fast-burning launching charge is required, and some need to be equipped with a blank cartridge recoil booster at the muzzle to complete the automatic action. The head blank cartridge is equipped with a bullet made of plastic, wood or paper. When fired, the bullet breaks apart and falls to the ground as soon as it exits the muzzle. Some plastic bullets and shells are integrated, the bullet is pre-fabricated in sections, and when launched, the bullet breaks apart in the chamber without separating from the shell. A chamber assist booster is required to assist the firearm to complete the automatic action.

[0003] At present, the Chinese army promotes live combat training systems in exercises to promote live combat training. Blank cartridges are widely used in training. However, the existing blank cartridges have the following defects:

[0004] 1. The headless blank cartridge is difficult to achieve a sensory experience basically consistent with live firing, which is not conducive to quickly adapting to and mastering the shooting essentials of firearms, and a blank cartridge recoil booster needs to be installed at the muzzle, which is not convenient to operate.

[0005] 2. The headless blank cartridge is not suitable for grenade launcher training, and the structure of the current head blank cartridge is suitable for bullets but not for grenades. There is no matching blank cartridge for the current grenade launcher to meet the training requirements.

[0006] Therefore, it is urgent to develop a blank cartridge that can automatically disintegrate after the bullet is discharged as a primary shooting training bullet, which is suitable for grenade launcher training, fully simulates the battlefield atmosphere and improves the exercise effect. SUMMARY

[0007] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application provides a full-shaped blank cartridge which can be disintegrated after the bullet is discharged by using the launching energy, and the sensory experience of which is basically consistent with live firing.

[0008] The technical scheme adopted by the present application to solve its technical problems is:

[0023] Figure 1 This is a schematic diagram of the structure of a blank cartridge that utilizes launch energy to disintegrate after leaving the barrel, as provided by the present invention. Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] This embodiment provides a fully-formed blank cartridge 1 that utilizes launch energy to complete the disintegration of the projectile after leaving the barrel, as shown in the attached figure. Figure 1As shown, the full-form blank cartridge 1 consists of a propellant charge 10 and a projectile 20. The tail of the projectile 20 is fitted inside the propellant charge 10. The propellant charge is a direct application of existing technology and will not be described in detail here. The projectile 20 in this embodiment includes a projectile body 201, a wind cap 202, a pressure limiting plate 203, and a counterweight 204. The projectile body 201 is a cylindrical structure with one end sealed and the other end open. The sealed end is provided with a ignition hole 2010, which allows the high-temperature and high-pressure gas generated by the propellant to enter the projectile body. The ignition hole 2010 is covered by the pressure limiting plate 203 on the outside of the sealed end, and the sealed end is partially assembled inside the propellant charge 10. The open end of the projectile body 201 is snapped together with the wind cap 202. The snap-connection between the wind cap and the projectile body facilitates the disassembly of the wind cap and the projectile body, and also simplifies assembly. The counterweight 204 fills the inner cavity of the projectile body 201 as a counterweight for the blank cartridge. Preferably, the weight of the blank cartridge 1 is made to be consistent with the weight of the standard cartridge, making it closer to the sensory experience of live-fire shooting.

[0027] Working principle: The firing pin strikes the primer, igniting the propellant in the propellant charge. The resulting high-temperature, high-pressure propellant gases propel the projectile forward. Simultaneously, the propellant gases overcome the pressure-limiting plate and continue acting on the counterweight, pushing it to impact the wind cap. Because the wind cap is snapped into the projectile body, it separates from the projectile body upon impact. The projectile disintegrates into three main parts—the projectile body, the counterweight, and the wind cap—one distance after leaving the muzzle. Due to air resistance, the projectile's velocity drops sharply, rendering it ineffective at 50 meters. This blank cartridge has the same weight as the standard cartridge, closely mimicking the sensory experience of live-fire shooting and meeting troop training requirements.

[0028] Example 2

[0029] Based on Example 1, this example further designs the counterweight filling material, preferably as shown in the attached figure. Figure 1 As shown, the counterweight filling 204 in this embodiment includes a push plate 2041, an elastic material 2042, and several counterweight pads 2043. The push plate 2041, the elastic material 2042, and the several counterweight pads 2043 sequentially fill the inner cavity of the projectile 201 from the sealed end to the open end, and are then fastened and pressed by the wind cap 202. Specifically, in the counterweight filling of this embodiment, the counterweight pads 2043 can be made of metal and are mainly used to adjust the weight of the projectile so that it achieves the same effect as the weight of the standard projectile. In other embodiments, other materials can also be used, and there is no limitation here. Under the action of the propellant gas, the push plate 2041 pushes the counterweight pads 2043 via the elastic material 2042. The elastic material, as a buffer, can be made of rubber or silicone.

[0030] Example 3

[0031] Based on Example 2, as shown in the appendix Figure 1 As shown, the counterweight filling material 204 in this embodiment also includes a separator 2044, which is disposed between two adjacent counterweight pads 2043. In this embodiment, the separator 2044 can be made of padding paper to buffer the impact force between the counterweight pads; in other embodiments, the separator can also be made of other materials, such as plastic sheets.

[0032] Preferably, the separator 2044 is an annular separator.

[0033] In any of the above-described embodiments, as shown in the appendix Figure 1 As shown, the hood 202 is shaped like a frustum of a cone, with a female buckle 2022 at its bottom. The open end of the spring body 201 is provided with a male buckle 2012 that matches the female buckle 2022. The hood is made of a lightweight material, such as plastic.

[0034] Preferably, a blind hole 2020 is provided at the head of the wind cap 202. The blind hole can increase the wind resistance of the wind cap and reduce the velocity of the projectile after it leaves the barrel.

[0035] In any of the above embodiments, the blank cartridge 1 is a grenade or a large-caliber bullet, wherein the grenade satisfies the training requirements of the grenade launcher and fills the gap in blank cartridges for grenades.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
