The specific embodiment

Fig. 1-Fig. 3 has reflected the structure of the utility model embodiment one, the utility model comprises rocket 1, picture and text curtain 2, parachute 3 and unpacking propellant 4 as can be seen from Figure 1, parachute 3 is connected with picture and text curtain 2, picture and text curtain 2 is rolled into tubular places rocket 1 together with parachute 3 rocket launcher 11, one dividing plate 12 is arranged at rocket launcher 11 bottoms, is fuel chambers 13 below the dividing plate 12; Picture and text curtain 2 has a curtain 21 that can curl and can launch, and the one side of this curtain 21 is fixed with many lists and props up fireworks 22 and chapelet 24, and chapelet 24 should exceed single fireworks 22, to prevent that single fireworks 22 from being damaged by pressure.Single fireworks 22 discharge according to the literal or the figure of prior design, discharging is " welcome " two words as shown in Figure 2, then with these single fireworks polyphone that go between fast, arrive total lead-in wire 221, total lead-in wire 221 has one section to be section at a slow speed, section adopts common igniting leads at a slow speed, and its seat can be connected in total lead ends as required or be connected in total lead-in wire interlude, and 221 the end of always going between stretches into rocket fuel chamber 12 upper stratas.Unpacking propellant 4 should be placed at the top of rocket launcher 11, can also place at the stack shell of rocket launcher 11, and its lead-in wire adopts fast lead-in wire, and lead terminal also extends rocket fuel chamber 12 tops.When the fast burning-out of fuel of rocket 1, the lead-in wire 41 of unpacking propellant 4 and total lead-in wire 221 of single fireworks are all lighted, unpacking propellant 4 is blown the loam cake of rocket launcher 11 rapidly, picture and text curtain 2 discharges, and is suspended on the (see figure 2) of drifting in the air by parachute 3, this moment total lead-in wire 221 the mistake of section at a slow speed, enter quick lead-in wire, rapidly single fireworks 22 are lighted, will be shown sparkling picture and text (" welcome ") in the air, express people's heartfelt wishes to one's heart's content.The curtain 21 of picture and text curtain 2 in the present embodiment, what adopt is that batten and rubber band are made, promptly wear all battens and form wooden curtain with line, again in wooden curtain fixing return unit such as rubber band or spring (see figure 3) simultaneously, wooden curtain not only can be curled but also can reset flattening, form the curtain that can curl and can flatten that we need, should simultaneously bore many jacks 23 that is used for fixing single fireworks at wooden curtain when making wooden curtain, single fireworks 22 are inserted in the jack 23, chapelet 24 adopts bamboo nail to order on wooden curtain, chapelet 24 after fixing should exceed single fireworks 22, when picture and text curtain 2 curls toward single fireworks 22 1, an axle support 25 also should be arranged, picture and text curtain 2 is twisted in the support 25, chapelet 24 heads on axle support 25, and avoid damaging by pressure single fireworks 22, on the dividing plate 12 of rocket launcher 11 bottoms, dig simultaneously recessed 14 (see figure 1)s, total lead ends adopts fast, and lead-in wire passes described dividing plate 12 from the fuel chambers upper strata of rocket 1, pass described recessed 14 again and arrive total section at a slow speed that goes between, section is to guarantee that unpacking propellant blows rocket launcher 11 earlier at a slow speed, allow picture and text curtain 2 launch, arrive the list that quick lead-in wire ignites rapidly on it then and prop up fireworks 22, needn't be with the axle support if the picture and text curtain is rolled up outward.The utility model picture and text curtain 2

Embodiment has multiple.

Embodiment two:

The curtain 21 of picture and text curtain 2 can adopt plastic drapery, has the slotting tube that many fixedly lists prop up fireworks on the plastic drapery, because plastic plate itself has certain elasticity, and flattenings of not only can having curled but also can reset, so meet our requirement to curtain.

Can also adopt bamboo curtain splint to make to described curtain 21.

Embodiment three:

This is the embodiment of figure energy conversion.Single fireworks 22 discharge according to layer in this embodiment, all lists of every layer prop up fireworks and arrange into a width of cloth picture and text, the lead-in wire string props up the head end of fireworks at all lists in same width of cloth picture and text, between different picture and text, the tail end that arbitrary list props up fireworks in the picture and text of setting off earlier with after arbitrary list props up fireworks in the picture and text seted off head end link to each other, as shown in Figure 5, single fireworks of present embodiment have discharged three layers, every layer is all propped up fireworks by all lists and lines up a width of cloth picture and text, successively set off by outer course bottom, can have three kinds of different picture and text to represent aloft, different like this picture and text one width of cloth width of cloth are seted off, and make the picture and text that present that multiple variation take place in the air.It is the longest that outermost list props up the slotting rod of layer during making, and vice versa.

For for layer, figure simply also can discharge two secondary figure.

Embodiment four:

On the basis of above-mentioned embodiment, sometimes we wish that the stronger effect of playing up is arranged, therefore can on picture and text curtain 2, fix one piece of two pieces of fireworks display that do not wait or display shell, it sets off that direction tilts or vertically downward, if single fireworks 22 arrange into fairy maiden's apperance, can respectively put one or two piece of display shell at two cuff places, construct the fairy maiden that a work takes off and spread colored sight.
