Description

The polyphony firecrackers of lead are housed

＜one〉technical field: the utility model relates to firecrackers, particularly a kind of polyphony firecrackers that lead is housed.

＜two〉background technology: at present, the firecrackers of buying on market all are to weave with the firecrackers of outer lead one by one, form a string 100 sound, 500 sound, 1,000 sound or more the firecrackers of the polyphony people that act in collusion to make each other's confessions set off.This firecrackers are because each all has outer lead, and each firecrackers has only sounds, so manufacturing and knitting process complexity, the productive labor amount is big, cost height, weak effect.Because each firecrackers all is with outer lead, the lead-in wire of firecrackers ruptures easily in insertion and braiding process and makes moist on the other hand, and these often cause the firecrackers bang rate of firecrackers low.

＜three〉summary of the invention: the purpose of this utility model will provide a kind of each firecrackers that polyphony is all arranged exactly, and the lead-in wire of each firecrackers all is embedded in the middle of the firecrackers enclosure, and the polyphony firecrackers that lead is housed one by one only need 2 external long blasting fuses to set off when being made into a lot of firecrackers.The utility model is to realize like this.Firecrackers shell bottom dress one deck fixative a paper cylinder, adorn an interior fuse at the bosom of shell then, again in the firecrackers shell on the fixative of bottom from the bottom up successively between dress ring medicine, fixative multilayer, ring medicine aspect dress one deck at last layer again and connect gunpowder as binding layer, this has just made the complete polyphony firecrackers that lead is housed.Gather into folds the firecrackers that lead is housed one by one are horizontal then, horizontal when folded the company's of being equipped with gunpowder of each firecrackers layer that binds want and be placed on same end face, then with paper self-adhesive tape will be one by one firecrackers tie into a string firecrackers admittedly, company's gunpowder of a string firecrackers bind end face be close to side by side two long outside fuse, and fixed with paper self-adhesive tape, at last these a string firecrackers are bandaged with paraffin paper, just formed a string complete firecrackers.When setting off, as long as light the outer the end of a thread of igniting, outer fuse burns from top to bottom, at first make company's powder burning of going up firecrackers most, light the interior fuse in the firecrackers, cause going up most the interior the superiors of firecrackers shell sound medicine and explode, the then second layer, the 3rd layer ... ringing medicine explodes, second firecrackers that meanwhile outer fuse is lighted these string firecrackers again begin to explode, and explode so one by one, can explode putting in order the string firecrackers.The utility model economical with materials, production technology is simple, be fit to mechanization production again, and production cost is low, the firecrackers bang rate height, firework display effect is good, and is safe and reliable, and its appearance provides a kind of desirable polyphony firecrackers that lead is housed for people.

＜four〉description of drawings: 1-firecrackers shell, 2-rings medicine, fuse in the 3-, 4-connects gunpowder, 5-fixative, the outer fuse of 6-, 7-paper self-adhesive tape, 8-paraffin paper.

＜five〉specific embodiment: describe most preferred embodiment below in conjunction with accompanying drawing.

Accompanying drawing 1 is the utility model internal structure schematic diagram.

Accompanying drawing 2 is structural representations that the utility model builds up a string firecrackers.

With reference to accompanying drawing 1, columnar firecrackers shell (1) is to form with big gun material paper roll system, the inner bottom of shell (1) is equipped with one deck fixative (5), then at the inner interior fuse of middle device (3) of shell (1), in shell (1), adorn one deck again on the fixative (5) of bottom from the bottom up successively and ring medicine (2), one deck fixative (5), one deck rings medicine (2), one deck fixative (5), one deck rings medicine (2), one deck fixative (5), one deck rings medicine (2), one deck fixative (5), and the superiors refill one deck and ring medicine (2), on the superiors' sound medicines (2), refill one deck and connect gunpowder (4), just formed complete four crack of a whip big guns that interior fuse (3) is housed as binding facing layer.And the loud number of firecrackers depends on that then what of the number of plies ring medicine (2) and fixative (5) in the shell (1) fills successively.

With reference to accompanying drawing 2, horizontal the gathering into folds of the firecrackers that lead is housed one by one (1), horizontal when folded each firecrackers (1) company's of being equipped with gunpowder (4) layer that binds want and be placed on same end face; Then with paper self-adhesive tape will be one by one firecrackers tie into a string firecrackers admittedly, company's gunpowder (4) of a string firecrackers bind layer end face be close to side by side two long outside fuse (6), and fixed with paper self-adhesive tape (7), at last these a string firecrackers are bandaged with paraffin paper, just formed a string complete firecrackers.The number of the polyphony firecrackers that the horizontal closed assembly of a string firecrackers is leaded depends on the needs, and is four crack of a whip big guns as firecrackers, and then 100 sound are a string then horizontal folded 25, horizontal folded 250 of a string need of 1000 sound ...
