Abstract
The utility model relates to the field of ballistic design, in particular to a gas-tight ring used in a fragile armor-piercing projectile; the gear tooth ring comprises a ring body, wherein three cuboid-shaped tooth bodies are uniformly distributed and connected on the outer side wall of the ring body, and a cavity in the ring body is respectively an upper round platform cavity, a cylindrical cavity and a lower round platform-shaped cavity from top to bottom; the height of the upper round platform cavity is 0.1mm, the height of the cylindrical cavity is 0.79mm, and the height of the lower round platform cavity is 1.11 mm; the utility model discloses an adopt reasonable closed gas ring appearance and pack into in the breakable armour piercing bullet of X millimeter multiple-effect, guarantee to seal the middle gap of bullet core and bullet support, gunpowder gas is scurried into from the rear when preventing the transmission, ensures that the flight of full bullet is not influenced. And the annular surface and the contact surface of the bullet core form 55 degrees, so that the gap between the annular surface and the bullet core and the bullet holder is more effectively sealed, and the normal flight of the whole bullet is effectively ensured.
Description
Technical Field
The utility model relates to a trajectory design field, concretely relates to gas trap ring that is arranged in breakable armour-piercing bullet.
Background
At present, the gap between the core and the bullet holder in the X-millimeter multi-effect fragile armor piercing bullet structure is complex, and the common annular structure can not meet the technical index requirement of the closed gas ring, so that higher requirement is provided for the shape design of the closed gas ring.
To realize the function of the gas-tight ring, the performance index requirement can be met only by seeking a reasonable appearance structure, the X-millimeter multi-effect fragile armor piercing bullet core and the bullet holder are guaranteed to be arranged in a sealed gap, gunpowder gas is prevented from entering from the rear during launching, and the whole bullet is not influenced in flying.
Disclosure of Invention
The utility model overcomes prior art's is not enough, provides a gas ring that closes for among breakable armour-piercing bullet for the dress plays the effect of sealing the gap in the middle of breakable armour-piercing bullet warcore of X millimeter multiple-effect and bullet support.
For solving the technical problem, the utility model discloses the technical scheme who adopts does: a gas-tight ring used in a fragile armor-piercing projectile comprises an annular body, wherein three cuboid-shaped tooth bodies are uniformly distributed and connected on the outer side wall of the annular body, and cavities in the annular body are an upper round platform cavity, a cylindrical cavity and a lower round platform-shaped cavity from top to bottom; the height of the upper round platform cavity is 0.1mm, the height of the cylindrical cavity is 0.79mm, and the height of the lower round platform cavity is 1.11 mm.
When the air-tight ring is used, the air-tight ring is arranged between the X-millimeter multi-effect fragile armor-piercing bullet core and the bullet holder.
Compared with the prior art the utility model discloses following beneficial effect has:
the utility model discloses an adopt reasonable closed gas ring appearance and pack into in the breakable armour piercing bullet of X millimeter multiple-effect, guarantee to seal the middle gap of bullet core and bullet support, gunpowder gas is scurried into from the rear when preventing the transmission, ensures that the flight of full bullet is not influenced. And the annular surface and the contact surface of the bullet core form 55 degrees, so that the gap between the annular surface and the bullet core and the bullet holder is more effectively sealed, and the normal flight of the whole bullet is effectively ensured.
Drawings
Fig. 1 is a top view of the gas-tight ring of the present invention.
Fig. 2 is a view from a-a of fig. 1.
The figures are labeled as follows:
1-annular body and 2-tooth body.
Detailed Description
The present invention will be further described with reference to the following specific examples.
Examples
As shown in fig. 1 and 2, the gas-tight ring for the fragile armor-piercing projectile comprises an annular body 1, three cuboid-shaped tooth bodies 2 (the included angle between adjacent tooth bodies 2 is 120 degrees) are uniformly distributed and connected on the outer side wall of the annular body 1, and a cavity inside the annular body 1 is an upper round platform cavity, a cylindrical cavity and a lower round platform-shaped cavity from top to bottom; the height of the upper round platform cavity is 0.1mm, the height of the cylindrical cavity is 0.79mm, and the height of the lower round platform cavity is 1.11 mm.
The structure is that the structure between the inner bullet core and the bullet support gap of the X-millimeter multi-effect fragile armor piercing bullet structure is observed, a sample is trial-loaded, and finally the shape design of the closed gas ring is determined to adopt the circular ring three-tooth structure. When the air-tight ring is used, the air-tight ring is arranged between the X-millimeter multi-effect fragile armor-piercing bullet core and the bullet holder.
Further, the length of the tooth body 2 is 9mm, the width is 2mm, and the height is 2 mm.
Furthermore, the included angle between the annular surface of the upper circular truncated cone cavity and the horizontal plane is 173 degrees, and the included angle between the annular surface of the lower circular truncated cone cavity and the horizontal plane is 55 degrees; the annular surface and the contact surface of the bullet core form an angle of 55 degrees, so that a gap between the annular surface and the bullet core and the bullet holder can be effectively sealed, and normal flying of the whole bullet can be effectively guaranteed.
Further, the minimum inner diameter of the annular body 1 is 8.8mm, and the outer diameter of the annular body 1 is 15 mm.
By matching with X-millimeter multi-effect fragile armor piercing bullet, the product performance is proved to meet the requirement, and the reasonable design of the shape of the closed gas ring is deduced.
