Description
Technical Field
The utility model belongs to the technical field of high-speed loading test, concretely relates to high-speed loading bullet of inferior bore pole shape bullet drags structure.
Background
The bullet drags and is the essential factor that adopts non-imparting of spin high speed loading test equipment such as slide chamber rifle to carry out the loading test, plays the effect of airtight powder gas and drive pellet under test in this type test system, and bullet drags the structure and has the important influence to test parameters such as pellet loading speed, flight attitude, angle of attack.
The common projectile dragging structure can meet the requirements of small-size projectile high-speed loading tests, but the structure has the problems of poor in-bore motion attitude, overturning, large attack angle, difficulty in separation of the projectile dragging and the like on the secondary-caliber rod-shaped projectile high-speed loading tests, and the test requirements of the secondary-caliber rod-shaped projectile high-speed loading tests cannot be met. Therefore, it is necessary to design a high-speed loading bullet trailer structure suitable for the trajectory of a secondary caliber rod-shaped bullet.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned weak point to a structure is dragged to the high-speed loading bullet of bullet that once bore pole shape that simple structure, bullet flight stability are good, the separation bullet of being convenient for drag the structure is dragged.
In order to achieve the above design purpose, the utility model adopts the technical scheme that: the utility model provides a structure is dragged to high-speed loading bullet of bar-shaped projectile of inferior bore, drags including broken piece projectile, split bullet, broken piece projectile middle part is equipped with the gas ring groove that closes, the gas ring groove endotheca card that closes has the gas ring that closes, broken piece projectile tail end is equipped with the end and drags, the front end of broken piece projectile is equipped with the adapter, the split bullet drags surperficial both ends and all is equipped with centering belt, the split bullet drag the inner wall both ends all seted up with broken piece projectile front end adapter matched with draw-in groove, the split bullet drags the draw-in groove of seting up through the inner wall tip to clamp and be fixed in the linking of broken piece projectile front end is overhead.
The split bullet holder clamped and fixed on the connecting head at the front end of the fragment bullet is formed by combining three split bullet holders and forms a column shape.
Compared with the prior art, the utility model has the advantages that:
the novel projectile shooting device has the advantages that during testing, the movement attitude in the projectile chamber and the flying attitude after the projectile is discharged from the muzzle are good, the attack angle is small, and the testing requirements can be met; the structure is convenient for separating the bullet from the bullet, and can effectively eliminate the influence of the bullet on the test result caused by the collision of the bullet with the target; can effectually prevent that secondary caliber bullet from striking the bore when the bore internal motion, do benefit to the protection barrel. The utility model discloses simple structure, with low costs, the shot is better, the angle of attack is less at the flight gesture of thorax internal motion gesture and after going out the muzzle when the experiment, can satisfy experimental requirement.

Description of reference numerals: 1-broken pill, 2-split pill drag, 3-closed air ring, 4-bottom drag, 5-centering belt and 6-clamping groove.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings. As shown in fig. 1-3: the utility model provides a structure is dragged to high-speed loading bullet of bar-shaped shot of inferior bore, drags 2 including broken piece shot 1, split bullet, broken piece shot 1 middle part is equipped with the closed gas ring groove, closed gas ring inslot cover card has closed gas ring 3, broken piece shot 1 tail end is equipped with the end and drags 4, broken piece shot 1's front end is equipped with the adapter, split bullet drags 2 surperficial both ends and all is equipped with centering band 5, split bullet drag 2 inner wall both ends all seted up with broken piece shot 1 front end adapter matched with draw-in groove 6, split bullet drags 2 draw-in grooves 6 that offer through the inner wall tip and clamps and is fixed in the linking of broken piece shot 1 front end is overhead.
The split bullet holder 2 clamped and fixed on the connecting head at the front end of the fragment bullet 1 is formed by combining three split bullet holders and forms a column shape.
When the utility model is used, the specific size of the selected projectile support is determined according to the size and the centering requirement of the projectile body, the air-tight ring 3 is tightly sleeved in the air-tight ring groove in the middle of the fragment projectile 1, and then the collet is pressed into the bullet shell to reach the air-tight end face; and then putting the bottom support 4 of the fragment projectile 1 upwards on an assembly platform, mutually clamping the three split projectile supports 2, closely attaching the three split projectile supports to the outer surface of an adapter at the front end of the fragment projectile 1 with the secondary caliber to form a column, finally uniformly coating 502 glue on the bottom of the formed cylindrical split projectile support, bonding the cylindrical split projectile support coated with the glue with the adapter at the front end of the fragment projectile 1, and filling the cylindrical split projectile support coated with the glue into a ballistic gun bore to perform a speed loading test after the glue is solidified.
