Detailed description of the invention
Detailed description of the invention of the present utility model is introduced in detail below in conjunction with accompanying drawing.
As shown in Figures 1 to 6, the fireworks launch holder structure 100 of the present embodiment one can be interconnected by some cylindrical shells 1 and form, and the present embodiment one can be interconnected by four cylindrical shells 1, by this to form the geometry framework of rectangle (square).
Each cylindrical shell 1 has openend 11 and a closed end 12, the taper accommodation space 13 of closed end 12 inside in convergent; Therefore, gunpowder 4 is inserted after in cylindrical shell 1, because of the pyramidal structure of gravity and taper accommodation space 13, gunpowder 4 is concentrated further, when pyrotechnics 5 is placed in after in cylindrical shell 1, thus the explosive force of strengthening gunpowder 4, and then increase the transmitting power of the pyrotechnics 5 be arranged in cylindrical shell 1.
Outside the geometry framework of the present embodiment one cylindrical shell, cylindrical shell extension stretches out recessed inserts 2 and a tuck pointing part 3, in order to the recessed inserts 2 corresponding with other one group of geometry framework and the removably mutual concavo-convex interlocking of tuck pointing part 3; By this, just to place multiple pyrotechnics with sequential filming simultaneously.
As shown in Figure 4, the gas leakage when bottom that lead-in wire is arranged on taper accommodation space prevents propellant ignition.The concrete set-up mode that goes between is as follows: the bottom of cylindrical shell 1 is provided with a groove 7, lead-in wire 6 is arranged in groove 7 and lead-in wire 6 is communicated with bottom taper accommodation space 13, cylindrical shell 1 is arranged on base 8, base 8 is provided with the projection 9 matched with described groove 7 size and position, cylindrical shell 1 to be installed on protruding 9 by groove 7 thus to be fixed on base 8, and lead-in wire 6 is fixed in groove 7 with coordinating of groove by protruding.
