Description

TECHNICAL FIELD

[0001] The present application relates to a kind of artillery simulator shell, specifically, a kind of simulation shell is adopted warhead, shell and the structure such as ball support, spring, interlock mechanism, guide cylinder and core cylinder installed in its inside is composed, belong to military training equipment field. BACKGROUND

[0002] With the development of national military patriotic education, more and more simulation weapons are displayed in each patriotic base.These simulation weapons such as artillery, self-propelled artillery, etc., have interactive functions, that is, they can meet the needs of visitors to operate.However, at present, due to the lack of simulation shells matched with simulation artillery, these interactive operations are basically empty operations, which greatly weakens the interactive effect. SUMMARY

[0003] In order to overcome the problem that simulation artillery lacks matched simulation shells, the present application provides a kind of artillery simulator shell.

[0004] The present application is realized by the following technical scheme: a kind of artillery simulator shell is composed of warhead and shell, which can be assembled together and quickly separated under the impact of simulation artillery striker.The bottom of the warhead has a tapered slope and a circle of grooves;The shell is composed of a shell body, a ball support, an interlock mechanism, an upper spring, a core cylinder, a lower spring and a guide cylinder, the ball support has multiple groups, which are evenly fixed and installed at the upper end of the shell body, the ball support has a vertical plate and a row of balls installed inside the vertical plate, which support and guide the warhead inserted into the shell;The guide cylinder is fixedly installed at the lower part of the shell body, the core cylinder is composed of an upper cylinder body, a lower cylinder body and a core cylinder protrusion;The diameter of the core cylinder is slightly larger than that of the guide cylinder, the core cylinder is sleeved on the guide cylinder, and the core cylinder can move up and down under the limitation of the guide cylinder;The lower spring is sleeved outside the core cylinder, the bottom of the lower spring is installed on the shell body, and the upper part of the lower spring is in contact with the lower surface of the core cylinder protrusion, which is compressed under the pressure of the core cylinder protrusion;The upper spring is sleeved outside the upper cylinder body of the core cylinder, and the bottom of the upper spring is fixedly connected to the upper surface of the core cylinder protrusion;The interlock mechanism is composed of a ring-shaped frame, a rotating shaft and a support, the evenly distributed support bases of the ring-shaped frame are installed on the support bases of the ring-shaped frame by the rotating shaft;The support has spring sheets installed outside, and the support has mounting holes, upper protrusions and lower protrusions, the upper protrusions can be embedded into the grooves of the warhead.

[0005] The ball support is a thick-walled block, the outer surface of the block is an arc surface, the curvature of the arc surface is consistent with the curvature of the inner wall of the shell, and a row of balls are embedded in the inner side of the block.

[0006] Further, when the bullet is installed in the shell, the core cylinder protrusion of the core cylinder contacts and props open the lower protrusion of the support, and under the lever action formed by the support mounting hole as a support point, the upper protrusion of the support is embedded in the groove of the bullet.

[0007] The support is a metal body with appropriate elasticity, and when the bullet is pressed into the shell under the action of external force, under the action of the bullet outer surface taper and pressure, the upper protrusion of the support is just clamped into the groove of the bullet, thereby positioning the bullet.

[0008] The benefit of this invention is that the simulated training bullet can achieve rapid separation of the bullet and the shell, and under the action of the spring, the bullet can be ejected a certain distance from the shell, and the simulated artillery shell can be used non-destructively for multiple times. The setting of the guide tube guides the movement of the core tube, so that the core tube will not deflect when moving. The core tube protrusion in the middle of the core tube plays three roles. First, it sets the upper dead point for the lower spring, so that the length of the lower spring is limited to the middle of the bottom of the shell and the core tube protrusion, and the elastic force is applied to the core tube through the core tube protrusion; second, it serves as a mounting platform for the upper spring. The lower end of the upper spring is fixedly mounted on the core tube protrusion, and the upper end of the upper spring is free or in contact with the lower plane of the bullet. When the bullet is forcibly pressed into the shell, the pressure is transmitted to the core tube protrusion through the upper spring, and the core tube protrusion transmits the pressure to the lower spring, so that the upper spring and the lower spring are compressed at the same time, so that the elastic force is good. The invention relates to a method for preparing a projectile and a firing pin, wherein the upper protrusion of the support is compressed and the core barrel is moved toward the projectile under the strong impact force, thereby separating from the lower protrusion of the support. The support is then moved away from the projectile groove by the spring sheet, and the upper protrusion of the support is separated from the projectile groove by the spring sheet. The upper protrusion of the support is separated from the projectile groove by the spring sheet, and the projectile is separated from the projectile groove by the spring force of the upper and lower springs and the guidance of the ball support. The support is then moved away from the projectile, thus completing the firing simulation of the projectile. The support of the present invention is installed on the annular frame of the interlocking mechanism. The advantages of the present invention are that it facilitates the assembly of the projectile during processing and that the support is evenly distributed, thus forming a better mechanical effect on the projectile. The spring sheet installed on the support can open the upper part of the support when the lower protrusion of the support is not in contact with the core barrel protrusion, thus facilitating the installation of the projectile. The diameter of the circular hole at the bottom of the cartridge case is smaller than the diameter of the bottom of the core barrel, which acts as a limit to the movement of the core barrel and reserves space for the impact of the firing pin. The bottom of the core barrel has a thicker structure, which is designed to prevent damage to the firing pin when it hits. The ball support design has a thick-walled block. The exterior of the block is designed to be arc-shaped for easy assembly with the cartridge case. The curvature of the arc is consistent with the curvature of the inner wall of the cartridge case. A row of balls are embedded in the interior of the block. The ball support is installed inside the cartridge case to provide support and guidance for the insertion of the bullet. The use of balls greatly reduces the friction between the bullet and the support, allowing the bullet to quickly detach from the cartridge case under the action of the upper and lower spring forces.
