The technical purpose of the utility model is realized by the following technical scheme: a structure for increasing the drag of a projectile, comprising the projectile, characterized in that: the one end of projectile body is connected with the base, the base is kept away from and is equipped with a plurality of stoppers on the one end bottom surface of projectile body, and is two adjacent rotate between the stopper and be connected with the resistance piece, and is a plurality of center department between the stopper is provided with the connecting rod, the one end fixed connection of connecting rod is on the base, and the other end is connected with the hood through the threaded rod, the one end that the hood has great bottom surface is equipped with the spacing groove that is used for restricting the resistance piece, the bottom surface center department of spacing groove still is equipped with the screw hole, the one end threaded connection that the connecting rod was kept away from to the threaded rod is in the threaded hole

Furthermore, the resistance piece comprises a rotating part and a wind resistance part, the rotating part is rotatably connected with the limiting block, and the wind resistance part is limited on the surface of the connecting rod by the limiting groove.

Further, the stopper is fan-shaped structure, and both ends all are equipped with first through-hole, be equipped with the second through-hole with first through-hole looks adaptation in the rotation portion, pass first through-hole and second through-hole through the fixed axis and be connected between stopper and the rotation portion.

Furthermore, a plurality of the rotating parts are combined, so that a relatively complete cone shape is formed among the rotating parts, the blast cap and the base.

In conclusion, the utility model has the following beneficial effects: this kind of a structure for increasing projectile resistance, one end at the projectile body sets up the base, be equipped with the resistance piece that is used for increasing the projectile body resistance when flight on the base, before not flying, the resistance piece is fixed on the lateral wall of connecting rod by the hood, after the projectile body flies certain safe distance, the hood separates completely with the resistance piece, the resistance piece does not receive the hood restraint, under the resistance of wind, freely divide into 3, the projectile body receives the resistance sharply increase after the resistance piece opens, the bullet shape coefficient changes, the flight is unstable, fall rapidly, reach and make army's training, exercise warning scope is little, and safe and reliable, train convenient to use's effect.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1 to 5, a structure for increasing projectile resistance, including projectile body 1, projectile body 1's one end is connected with base 2, base 2 is kept away from and is equipped with a plurality of stoppers 3 on the one end bottom surface of projectile body 1, it is connected with resistance piece 4 to rotate between two adjacent stoppers 3, center department between a plurality of stoppers 3 is provided with connecting rod 5, connecting rod 5's one end fixed connection is on base 2, the other end is connected with hood 7 through threaded rod 6, hood 7 has the one end of great bottom surface and is equipped with the spacing groove 8 that is used for restricting resistance piece 4, the bottom surface center department of spacing groove 8 still is equipped with screw hole 9, threaded rod 6 keeps away from one end threaded connection of connecting rod 5 and in screw hole 9
