Abstract
The utility model discloses a starter capable of predetermining a direction and a position of fireworks. The starter capable of predetermining the direction and the position of the fireworks comprises a cylindrical starter seat and a firework launch barrel which is placed on the cylindrical starter in sleeved mode. The starter seat comprises a base seat and a body. The body is provided with three to eight empennage slots which are distributed along a radius line of a cross section of the body and penetrates through the circumference of the body along the radial direction and the axial direction of the body, and each empennage slot is evenly distributed along the peripheral direction of the body. A gun propellant cavity is placed in an inner cavity at the upper end of the body, an opening of the gun propellant cavity is connected with a circular arc transition slope face, and a vertex of the slope face is connected with an opening at the upper end of the body. When a user sets off the fireworks, the user places the fireworks with corresponding emages into the launch barrel and inserts the emages of the fireworks into the empennage slots completely to enable the emages to be protected. The circular arc transition slope face and the opening of a launch cavity are pressed by a spherical projectile body so that the launching pressure and the launching height are guaranteed. The fireworks do not spin any more when blasted off, and the direction of blasting is determined to ensure that display angles of pictures in the air meet appreciating requirements.
Description
Technical field
The utility model relates to a kind of orientation location emitter of display shell.
Background technology
The structure of existing display shell is referring to Fig. 1, body is comprised of episphere 1, lower semisphere 2, lower semisphere 2 bottom devices pass fire lead-in wire 4 and emission cartridge bag 3, a plurality of bright pearls are arranged according to predetermined pattern be embedded in the mixture of opening dryness-fire medicine and filler of display shell inner chamber, the arrangement surface of bright pearl is positioned at the faying face 5 of episphere 1 and lower semisphere 2, when display shell is put into launching gun barrel 6, the plane parallel at emission port 7 places of faying face 5 and launching gun barrel 6 is opened the bright pearl of lighting after quick-fried and is formed corresponding skydive picture.But be with the rotation mode lift-off during emission of display shell spheroid, cause the angle of skydive picture and horizontal plane (ground) to be difficult to control, probably can't see best appreciation effect so that appreciate the fireworks display performance spectators of skydive on ground.
Fireworks display airborne installation empennage can be so that display shell no longer with rotation mode lift-off, number be the utility model patent " oriented launching fireworks " of CN 2442220Y such as Granted publication number for the utility model patent of CN 2439011Y " a kind of display shell with directed empennage " and Granted publication.But these devices are because the structure existing problems of emitter cause its emission or orientation can't realize or be difficult to producing a desired effect.
