Example one

The embodiment provides a full-shape blank package bullet 1 which is disassembled by autorotation after the bullet is launched, as shown in fig. 1, the full-shape blank package bullet comprises a launching charge 10 and a bullet 20, the tail of the bullet is assembled in the launching charge, and the launching charge is directly applied mechanically in the prior art and is not described herein again. The projectile 20 of the present embodiment includes a body 201, a hood 202, a locator post 203, and a plurality of resistance rings 204. One end part of the projectile body 201 is assembled in the propellant charge 10, and the other end of the projectile body is in threaded connection with the positioning column 203 in a direction opposite to the projectile discharging rotation direction. Generally, the projectile rotates rightwards due to the restriction of rifling, so that the projectile body and the positioning column are connected through left-handed threads, and after the projectile is shot, the projectile body and the positioning column are separated through autorotation of the projectile. The other end of the positioning column 203 is fixedly connected with the hood 202; the resistance rings 204 are stacked and arranged on the positioning column 203 in a penetrating manner, are positioned between the projectile body 201 and the wind cap 202 and are tightly pressed by the wind cap 202, and the diameter of the resistance rings 204 is matched with that of the projectile body.

Preferably, as shown in fig. 1 and fig. 2, each resistance ring 204 of the present embodiment is formed by splicing two semicircular resistance plates 2041 into a ring shape, the inner diameter of the ring shape matches with the diameter of the positioning column 203, and the arc-shaped grooves of the two resistance plates 2041 are fastened on the positioning column to form the resistance ring.

Preferably, the resistance ring 2041 of the present embodiment is made of an aluminum material, which has the advantage of light weight; the hood 202 and the positioning column 203 can be made of plastic materials.

The utility model discloses a disintegration principle behind the shot play thorax as follows:

the firing pin impacts the primer of the propellant charge to ignite the propellant powder, the formed high-temperature high-pressure gas pushes the projectile to move forwards, the projectile rotates rightwards under the restraint of the rifling, the projectile body and the positioning column are gradually rotated and separated until air resistance is applied to the projectile body and the positioning column, the projectile body and the positioning column are completely separated, after the positioning column and the hood are screwed out, the resistance piece is loosened and thrown forwards through centrifugal force and kinetic energy, as shown in figure 5, the projectile body is completely disintegrated at about 10 m after being taken out of the chamber, the disintegrated object is thrown forwards and has sharp drop of speed under the air resistance, and the thrown object at 50 m can not puncture 25 mm pine targets, so that the training requirement is met.

Example two

On the basis of the first embodiment, in order to ensure that the positioning column and the elastic body can be separated smoothly, the positioning column and the elastic body cannot be screwed excessively, and in order that the resistance ring cannot be separated radially after being installed, in this embodiment, a groove 2041a is formed in one side of each resistance plate 2041, a boss 2041b matched with the groove is formed in the other side of each resistance plate, and the resistance plates are stacked one on another and are radially limited by the grooves and the bosses. The bottom of the hood 202 is provided with a limit groove matched with the boss 2041b for accommodating the boss and realizing the compression resistance piece of the hood. Preferably, the positioning column 203 and the blast cap 202 of this embodiment are screwed by using threads in the same rotating direction as the shot discharging direction, that is: adopt right-handed screw and reference column spiro union, after the shot launches, because hood and reference column are right-handed screw, consequently hood and reference column can not separate at the in-process of rotation. The projectile body, the positioning column, the resistance pieces and the wind cap are assembled in the connection mode, and the reliability of the projectile in the self-rotation process can be guaranteed.

In the above embodiment, as shown in fig. 3 and fig. 4, the hood 202 includes a cap body 2021, a pressing plate 2022 and a plurality of rib plates 2023, the pressing plate 2022 is disposed at the bottom of the cap body, the plurality of rib plates 2033 connect the cap body 2021 and the pressing plate 2022, and the hood is an integral structure formed by plastic injection molding. The hood with the structure increases the resistance in rotation after the projectile is taken out of the chamber, and is beneficial to the thorough separation of the projectile body and the positioning column.

In the above embodiment, the weight of the blank cartridge 1 is the same as that of the standard cartridge, so that the sense experience of firing practice is closer.

In the above embodiment, the blank grenade 1 is a grenade or a large-caliber bullet, wherein the grenade meets the training of a grenade launcher, and fills the blank of the grenade on the blank grenade.

The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification of the present invention, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
