Description

Technical Field

[0001] This utility model relates to the field of artillery projectile launching technology, specifically to a sabot assembly suitable for various different projectiles. Background Technology

[0002] The sabot is a key component of sub-caliber projectiles. It is mainly used to guide the projectile body in the barrel and separate it from the projectile core during flight to reduce air resistance and improve armor-piercing effect.

[0003] For example, Chinese utility model patent with announcement number CN220230259U discloses a sabot assembly for an air gun projectile, which can launch projectiles of various specifications by changing different sabots, thus enabling a single gun barrel to launch projectiles of multiple specifications.

[0004] However, the aforementioned patents and existing technologies have the following drawbacks in use: although by replacing different sabots, a single gun barrel can fire projectiles of various sizes, different sabots still need to be prepared for different projectiles, which requires different design and manufacturing processes, thus increasing the design and manufacturing costs of the sabots. Utility Model Content

[0005] The purpose of this invention is to solve the problem that different projectiles require different sabots, which increases the design and manufacturing cost of sabots. This invention provides a sabot assembly suitable for a variety of different projectiles.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A sabot assembly suitable for various projectiles includes a cartridge case, a sabot fixedly inserted into the top of the cartridge case, a projectile inserted into the center of the sabot, a limiting groove evenly formed on the upper and lower periphery of the center of the projectile, a compression strip slidably connected to the inner side of the sabot, and a bolt threadedly connected to the center of the sabot, with the inner side of the bolt rotatably connected to the compression strip.

[0008] Furthermore, the sabot adopts a three-lobed design, with compression strips and bolts provided on the inner side of each lobe.

[0009] Furthermore, the inner side of the extrusion strip is serrated and is adapted to the limiting groove. Through the cooperation between the extrusion strip and the limiting groove, the sabot and the projectile are stably limited, so that the sabot can better drive the projectile to make the initial firing.

[0010] Furthermore, a tail fin is fixedly installed at the bottom of the warhead to improve the stability of the warhead during flight.

[0011] Furthermore, an installation groove is provided on the outer periphery of the bottom fitting area of ​​the sabot, and positioning grooves are provided on the inner sides of both sides of the installation groove inside the sabot. A connecting strip is limited and fastened inside the installation groove by the positioning groove, thereby improving the stability of the sabot assembly.

[0012] Furthermore, the connecting strip is located between adjacent sabots, and when the sabot and the cartridge case are installed, the connecting strip is located on the inner side of the inner wall of the top of the cartridge case. After assembly, the top of the sabot forms a downward-recessed air-collecting groove. Air holes are opened inside the sabot. The upper part of the air hole is connected to the air-collecting groove, and the lower part of the air hole is connected to the positioning groove. The air-collecting groove allows the sabot to detach better under the action of drag during flight, and the air holes also allow the connecting strip to detach better.

[0013] Furthermore, the bottom of the sabot has a slanted groove, and a blocking ring is inserted upwards into the bottom of the sabot. The blocking ring also adopts a three-lobed design, and a slanted post is fixedly connected to the periphery of the blocking ring. The slanted post is located inside the slanted groove, and the blocking ring seals the bottom of the sabot and the projectile.

[0014] Furthermore, the outer inclined side of the inclined column is provided with barbs, which allows the blocking ring to be stably inserted upwards and to remain stably in contact with the outer edge of the bullet after the top of the blocking ring is squeezed and contacted.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the design of the inner bolt and the extrusion strip of the sabot, and the cooperation between the inner serration of the extrusion strip and the limiting groove of the outer part of the projectile, can stably clamp projectiles of different diameters by adjusting the extension and retraction of the extrusion strip, thereby improving the applicability of the sabot, avoiding the need to manufacture various sabots for different projectiles, and reducing the design and manufacturing cost of the sabot.

[0017] 2. This utility model, through the design of the bottom outer connecting strip and bottom blocking ring of the sabot, and the effect of the air collection groove on the connecting strip through the air hole, ensures that the sabot stably clamps the projectile, so that the sabot carries the projectile out stably. At the same time, the sabot can also quickly detach after firing, thereby reducing the drag on the projectile and ensuring the flight speed of the projectile. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] A preferred embodiment of the present invention, applicable to various projectiles, will be described in detail below, such as... Figures 1-10 As shown, a sabot assembly suitable for various projectiles includes a cartridge case 1, a sabot 2 fixedly inserted into the top of the cartridge case 1, the sabot 2 adopts a three-lobed design, each lobe of the sabot 2 is provided with a compression strip 4 and a bolt 5 on its inner side, a projectile 3 is inserted into the center of the inside of the sabot 2, a limiting groove 31 is evenly opened on the upper and lower outer periphery of the middle part of the projectile 3, the compression strip 4 is slidably connected to the inner side of the sabot 2, and the bolt 5 is threadedly connected to the middle part of the sabot 2, and the inner side of the bolt 5 is rotatably connected to the compression strip 4.

[0031] The inner side of the compression strip 4 is serrated and is adapted to the limiting groove 31. Through the cooperation of the compression strip 4 and the limiting groove 31, the sabot 2 and the projectile 3 are stably limited, so that the sabot 2 can better drive the projectile 3 to make initial firing. The bottom end of the projectile 3 is fixedly installed with a tail fin 32 to improve the flight stability of the projectile 3.

[0032] The bottom of the sabot 2 has an outer mounting groove 6, and the inner sides of the mounting groove 6 inside the sabot 2 have positioning grooves 7. The mounting groove 6 is secured by a connecting strip 8 through the positioning groove 7, thereby improving the stability of the sabot 2 assembly.

[0033] The connecting strip 8 is located between adjacent sabots 2, and when the sabot 2 is installed with the cartridge case 1, the connecting strip 8 is located on the inner side of the top inner wall of the cartridge case 1. After assembly, the top of the sabot 2 forms a downward-recessed air collection groove 21. Air holes 9 are opened inside the sabot 2. The upper part of the air holes 9 is connected to the air collection groove 21, and the lower part of the air holes 9 is connected to the positioning groove 7. The air collection groove 21 allows the sabot 2 to better detach under the action of drag during flight. Under the action of the air holes 9, the connecting strip 8 can also be better detached.

[0034] The bottom of the sabot 2 has a groove 10 at the fitting point. A blocking ring 11 is inserted upward from the bottom of the sabot 2. The blocking ring 11 also adopts a three-lobed design. An inclined post 12 is fixedly connected to the outer periphery of the fitting point of the blocking ring 11. The inclined post 12 is located inside the groove 10. The blocking ring 11 seals the bottom of the sabot 2 and the projectile 3. The outer inclined side of the inclined post 12 has barbs 121, which allows the blocking ring 11 to be stably inserted upward and to stay stably after the top of the blocking ring 11 is pressed and contacted with the outer periphery of the projectile 3.

[0035] The working principle of this utility model is as follows:

[0036] During assembly, based on the diameter of the projectile 3, the bolt 5 is connected to the projectile support 2 by thread. The bolt 5 is turned from the outside. During the rotation of the bolt 5, the inner end of the bolt 5 is connected to the limiting rotation of the compression strip 4, and the compression strip 4 is connected to the limiting sliding of the compression strip 4 inside the projectile support 2. This allows the position of the compression strip 4 inside the projectile support 2 to be adjusted, so that the compression strip 4 can stably clamp projectiles 3 of different diameters after the projectile support 2 is assembled.

[0037] During the process of the sabot 2 clamping the projectile 3, the serrations on the inner side of the compression bar 4 can be inserted into the limiting groove 31, thereby making the compression bar 4 and the projectile 3 stably connected.

[0038] After clamping the sabot 2 and the projectile 3, the connecting strip 8 is fastened between the outer sides of the bottom of the sabot 2 using the design of the mounting groove 6 and positioning groove 7 at the bottom of the sabot 2, thereby achieving stable clamping of the sabot 2. Then, using the design of the inclined groove 10 at the bottom of the sabot 2, the inclined post 12 of the outer side of the blocking ring 11 is aligned with the inclined groove 10, and the blocking ring 11 is inserted upward at the bottom of the sabot 2. During the upward movement of the blocking ring 11, the top of the blocking ring 11 can shrink inward and squeeze into contact with the outer side of the projectile 3, thereby achieving a seal between the bottom of the sabot 2 and the projectile 3. The barb 121 on the inclined post 12 allows the blocking ring 11 to remain stably after the seal is completed.

[0039] Finally, after filling the inside of the cartridge case 1 with gunpowder, the sabot 2 holding the bullet 3 is fixedly installed on the top of the cartridge case 1. During the installation process, the connecting strip 8 on the outer side of the bottom of the sabot 2 is inserted into the inside of the top of the cartridge case 1.

[0040] During launch, the sabot 2 and the warhead 3 are fired together. After firing, the air collection groove 21 on the top of the sabot 2 is exposed to wind, and under the action of wind resistance, the sabot 2 can unfold outward. Through the action of the air hole 9, the wind force can also enter the positioning groove 7, which can also disengage the connecting strip 8 that is fastened in the mounting groove 6, so that the sabot 2 can normally detach from the warhead 3, thereby reducing the air resistance of the warhead 3 during flight.
