The specific embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

With reference to Fig. 3, it is simplified in a kind of fireworks that preferred embodiment one of the present utility model provides, this fireworks inner tank body 7 comprises first cylinder 71 cylindraceous and second cylinder 72 of axially asking every arranging, between first cylinder 71 and second cylinder 72, through dividing plate 73, be connected, dividing plate 73 is provided with fairlead 735, fairlead 735 axially runs through along dividing plate 73, so that be arranged on lead 25 in fairlead 735 in the bottom of dividing plate 73 is communicated to first cylinder 71.The utility model is by being divided into traditional inner barrel in first cylinder 71 cylindraceous, second cylinder 72, in the middle of first cylinder 71 and second cylinder 72, through dividing plate 73, be connected, utilize dividing plate 73 to replace traditional lower seal in inner barrel of being located at, guaranteed that fireworks inner tank body 7 explosion time dividing plates 73 also can integral body blow, thereby while having avoided fireworks interior simplified 7 to produce ball clay and ball clay whereabouts when high-altitude explosion, hurt sb.'s feelings damage thing, the security that has improved firework display.

Preferably, in the present embodiment, dividing plate 73 adopts wood-fibred or pulp mixture to be made into integration, and has avoided like this fireworks interior simplified 7 when high-altitude explosion, to produce ball clay.

With reference to Fig. 4, in the present embodiment, dividing plate 73 comprises convex platform 731 and lower convex platform 733; Between convex platform 731 and dividing plate body, form First terrace 732, between lower convex platform 733 and dividing plate body, form second step face 734.The external diameter of convex platform 731 coordinates with first internal diameter of 71, and First terrace 732 contacts with first bottom of 71; The external diameter of lower convex platform 733 coordinates with second internal diameter of 72, and second step face 734 contacts with second top of 72.In the present embodiment, first 71 equates with second internal diameter of 72, therefore the external diameter of convex platform 731 also equates with the external diameter of lower convex platform 733.Preferably, between dividing plate 73 and first cylinder 71 and dividing plate 73 all adopt the bonding or tight fit connection of glue between 72 with second.

Fig. 5 shows the structural representation of embodiment bis-median septums 73.Embodiment bis-is with the difference of embodiment mono-: the structure of dividing plate 73 has been done to further improvement, at the end face of convex platform 731, be provided with the first arcwall face 731a of indent, thereby saved consumptive material and the manufacturing cost of dividing plate 73, and reduced the overall weight of fireworks inner tank body 7.

Fig. 6 shows the structural representation of embodiment tri-median septums 73.Embodiment tri-is with the difference of embodiment mono-: the structure of dividing plate 73 has been done to further improvement, be provided with the second arcwall face 733a of indent in the bottom surface of lower convex platform 733.

Fig. 7 shows the structural representation of embodiment tetra-median septums 73.Embodiment tetra-, on the basis of embodiment tri-, is provided with the first arcwall face 731a of indent at the end face of convex platform 731, thus consumptive material and the manufacturing cost of having saved dividing plate 73, and reduced the overall weight of fireworks inner tank body 7.

According on the other hand of the present utility model, a kind of fireworks are also provided, with reference to Fig. 8, comprise in the fireworks of fireworks main body 1 and above-described embodiment one simplifiedly 7, in fireworks, simplified 7 are located in the installing hole 11 of fireworks main body 1.Fireworks inner tank body 7 comprises first cylinder 71 cylindraceous, second cylinder 72.First cylinder 71 and second cylinder 72 axially spaced-apart settings, and the two is all connected with dividing plate 73.Second bottom of 72 coordinated with the inwall of installing hole 11 every 3 the end of through, and first top of 71 is provided with sealing 22, and first top of 71 coordinates with the inwall of installing hole 11 through upper cover 21.The end every 3 and second form the first cavity A that holds flight effect mixture 27 between 72, the end, forms with the bottom of installing hole 11 the second cavity B that holds bottom gunpowder 4 every 3, in the second cavity B, be provided with extend installing hole 11 outsides enter fire lead-in wire 5 and the lead-in wire 6 and be connected the lead 25 of the first cavity A and the second cavity B of firing.And in fireworks, first cylinder 71 inside of simplified 7 are provided with explosive mixture 24, and the fairlead 735 of lead 25 on dividing plate 73 stretches in first cylinder 71, for lighting explosive mixture 24.

The course of work of fireworks burnings is as follows: burning things which may cause a fire disaster, from the bottom of entering fire lead-in wire 5 and enter installing hole 11, ignites and is positioned at the bottom gunpowder 4 of installing hole 11 bottoms, and bottom gunpowder 4 burn rapidly, and the lead 25 that ignites, firing goes between 6 and flight effect mixture 27.When bottom gunpowder 4 burns, gas rapid expansion of moment produces boosting power, fireworks inner tank body 7 is under the effect of this boosting power, outlet along installing hole 11 rushes at sky, now, flight effect mixture 27 is lighted, to guarantee that fireworks inner tank body 7 afterbody in flight course discharges pearlite and produces fireworks; The moderate length of lead 25, makes fireworks inner tank body 7 when highest point, and burning things which may cause a fire disaster is introduced first cylinder 71 inside with the explosive mixture 24 that ignites, thereby guarantees in fireworks that simplified 7 blow at highest point, discharges pearlite and produce beautiful fireworks in high-altitude; The lead-in wire 6 that fires is introduced burning things which may cause a fire disaster in next fireworks tube, thereby makes by the simplified fireworks inner tank assembly forming in a plurality of fireworks, after only needing a burning things which may cause a fire disaster to introduce, can be lighted continuously and automatically easy to operate and safety.In the present embodiment, flight effect mixture 27 and explosive mixture 24 are the mixture of gunpowder and bright pearl.

It will be understood by those skilled in the art that simplified 7 fireworks interior simplified 7 that can also adopt in above-described embodiment two, embodiment tri-or embodiment tetra-in the fireworks in fireworks.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
