Embodiment Construction

[0020] see figure 2 , in the present invention, according to the needs of the discharge effect, the angle ∠D between the aerial modeling picture 206 and the horizontal plane 205 (ground) is called the display angle; The angles ∠C, ∠A, and ∠B formed by the plane 203 (or the plane 201 where the upper opening of the launching base body is located, or the plane 202 where the launching port of the launching barrel 10 is located) are called installation angles, and ∠C =∠A=∠B, ∠D=∠C=∠A=∠B when launching the cannon barrel 10 vertically; ∠C, ∠A or ∠B are equal to ∠D minus the launching cannon barrel 10 angle of inclination. According to the above relationship, the installation angle of the fireworks shell is set corresponding to the display angle. Make the display angle meet viewing needs.

[0021] see image 3 , reflecting a specific structure of the present invention, the directional positioning launching device of the fireworks shell comprises a fireworks shell launching barrel...

Abstract

The invention discloses a display shell with a fixed launch direction and a fixed launch position. The bottom of the display shell is provided with three to eight tail fins corresponding to tail fin inserting slots, the upper portions of the tail fins are arranged by surrounding a propellant bag of the display shell, and the inner edges of the lower portions of the tail fins are integrally connected. A mounting inclined angle of the display shell is arranged corresponding to a display inclined angle. The structural strength and directing and positioning capacity of the tail fins are enhanced, so that the display shell is prevented from spinning in liftoff, explosion direction is fixed, and aerial pattern display angle can be guaranteed conveniently and reliably to meet enjoyment requirements. Further, the display shell is high in compatibility to existing display shell production process and convenient for linkage.

Description

technical field [0001] The invention relates to a fireworks shell fired in a directional positioning. Background technique [0002] For the structure of the existing shells, see figure 1 , the missile body is composed of an upper hemisphere 1 and a lower hemisphere 2, the bottom of the lower hemisphere 2 is equipped with a fire transmission lead 4 and a propellant package 3, and a plurality of bright beads are arranged according to a preset pattern and embedded in the detonation powder of the inner cavity of the shell In the mixture with the filler, the arrangement surface of the bright beads is located at the joint surface 5 of the upper hemisphere 1 and the lower hemisphere 2. When the fireworks shell is put into the launching barrel 6, the joint surface 5 and the launching port 7 of the launching barrel 6 are located. The planes are parallel to each other, and the bright beads ignited after detonation form a corresponding aerial modeling picture. However, when the firew...
