Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a counterfeit bullet used in place of a real bullet in a gun loading test and a loading training, and more specifically, a bullet is held by a projectile or the like. However, the present invention relates to a fake ammunition suitable for a so-called throw-in type loading gun among the guns having a mechanism for loading the barrel.

(B) Conventional technology Used for loading test and loading training in a gun equipped with a mechanism for loading a bullet having a structure in which a warhead and a shell are integrated into a barrel while holding it with a bullet blasting machine. Test bullets and training bullets (collectively referred to as artificial bullets) generally have the following structure (see FIG. 4).

1) The warhead 20 and the shell 30 have a monoblock structure with a caulking structure.

2) A dummy fire tube 40 is screwed into the bottom of the warhead 20,
Also serves as a retainer for the caulking part.

3) The dimensions and external shape are almost the same as the actual bullet.

(C) Problems to be solved by the invention When the artificial bullet 50 is loaded on the barrel 11 of the throw-in type loading system, the artificial bullet 50 bounces at the position shown in FIG. 3 and the loading machine is adversely affected. There was a problem that the loading work was interrupted and the loading work had to be interrupted.

In addition, the bouncing of the pseudo bullet 50 may cause the pseudo bullet 50 to swing, and the outer side of the warhead 20 may be hit on the inner surface 12 of the barrel 11 to damage the warhead 20, shortening the service life of the pseudo bullet 50. Was the cause.

The present invention has been made in order to eliminate the drawbacks found in the above-described conventional counterfeit bullets, there is almost no rebound of the counterfeit bullets during loading, and the head of the bullet is less likely to be damaged with it. Moreover, it is an object of the artificial warhead to provide a pseudomanufactured bullet which can be used by partially processing a conventional member.

(D) Means for Solving the Problems The structure of the present invention for solving this problem is a warhead front part (2a) having a substantially conical outer shape forming a shell of a bullet and a front conical rear end. The warhead (2), which consists of the rear part of the warhead (2b) and has a screw (2c) on the rear end side of the rear part of the warhead, and the front end part (3a) which is almost cylindrical and is fitted to the front part of the warhead. A shell (3) having an internal thread (3b) screwed to the rear of the warhead on the end side, and a placebo (5) loaded with an axial gap (4) in the inner shell of the shell or the rear of the warhead (5). ) And, the gist is a pseudo-manufactured bullet (1). The placebo may be in the form of powder like the actual bullet, and the cylinder into which the placebo is inserted may be provided at the shell or at the rear of the warhead.

The reference numerals in parentheses indicate the corresponding members of the embodiments described later.

(E) Action When the warhead is thrown into the inner surface of the cavity by the action of throwing a fake ammunition into the barrel during loading operation, the placebo is gathered in the part away from the warhead inside the cartridge, that is, behind the cartridge. is there. When the warhead further penetrates into the cavity, as shown in FIG. 3, that is, the impact of the shell hitting the inclined portion of the chamber causes the artificial bullet to jump out of the cavity and bounce back to the rear of the barrel. , The placebo in the shell tries to collect on the warhead side due to inertia, and the force against the bounce force works, and as a result, the bounce of the fake bullet is prevented.

In other words, unlike conventional bullets, the conventional counterfeit bullets formed a rigid body with an integral structure, so there was no action to suppress the rebound during this loading, and therefore the conventional counterfeit bullets were incompletely loaded by the rebound. it is conceivable that.

(F) Example Hereinafter, the present invention will be described in detail with reference to the drawings showing the example. FIG. 1 shows a first embodiment of the present invention. A pseudo bullet 1 comprises a warhead front portion 2a having a substantially conical outer shape forming a shell of a bullet and a warhead rear portion 2b extending from a front cone rear end. Nari warhead 2 with a screw 2c on the rear end side of the warhead, and a substantially cylindrical front end 3a is fitted to the front part 2a of the warhead, and is screwed to the external thread 2c of the rear part of the warhead 2b on the rear end side. It is composed of a shell 3 having a female screw 3b, and a powder-like placebo drug 5 loaded in the shell 3 with a gap 4 in the axial direction. By connecting the external thread 2c and the internal thread 3b, the warhead 2 and the shell 3 can be integrally fastened.

FIG. 2 shows a second embodiment of the present invention. The artificial bullet 101 is a front part of a warhead having a substantially conical outer shape that forms the outer shell of a bullet.
A warhead 102 consisting of a cylindrical warhead rear portion 102b extending from the rear end of the front cone 102a and an external diameter portion 102c on the rear end side of the rear portion of the warhead and a female screw 102d on the inner diameter portion, and a substantially cylindrical shape. A female screw whose front end 103a is fitted with the front part 102a of the warhead and is screwed to the male screw 102c of the rear part 102b of the warhead at the rear end side.
A shell 103 provided with 103b, a powder-like placebo 5 inserted in the shell 103 with a gap 4 in the axial direction, and the screw.
It is composed of a lid 16 screwed into 102d. By connecting the male screw 102c and the female screw 103b, the warhead 102 and the shell 103 can be integrally fastened.

The operation of the embodiment will be described below with reference to FIG.

Since the operations of the first and second embodiments are the same,
I will explain together.

At the time of loading work, by throwing the artificial bullet 1 into the barrel 11 of the gun, the dummy drug 5 in the cartridge 3 (or the rear part 102b of the warhead) 5
Tries to push the warhead 2 into the cavity inner surface 12 in a state where the warhead 2 is gathered in a portion apart from the warhead 2, that is, in the rear of the artificial bullet 1. The warhead 2 is fitted into the inner surface 12 of the cavity, and the cartridge 3 hits the medicine chamber inclined portion 13 provided on the medicine chamber inner surface of the barrel 11. Due to the impact at this time, the dummy bullet 1 tries to bounce back from the barrel 11 to the right in FIG. 3, while the dummy drug 5 in the dummy bullet 1 moves to gather on the side of the warhead 2 due to inertial force. Therefore, the force that opposes the rebounding force works. That is, the loading work can be performed smoothly.

When the number of times the pseudo bullet is used becomes large and each part is damaged and needs to be replaced, either or both of the warhead 1 and the shell 3 may be replaced. In the case of any of the embodiments, the warhead 1 can be used by partially modifying the conventionally used one, which is advantageous when exchanging.

(G) Effect of the Invention As described above, according to the pseudo bullet of the present invention, the defect of imperfect loading can be significantly reduced as compared with the conventional pseudo bullet.

Further, as a result of being able to reduce the rebound of the counterfeit bullet in this way, damage of the warhead is significantly reduced and the life of the counterfeit bullet can be extended.
