Description

Firecrackers

The utility model relates to the pyrotechnic field, especially a kind of Firecrackers.

Commercially available and firecrackers that set off mainly contain three types at present, and the one, the gunpowder type: inner core is to be mixed with a nitre four sulphurs three wooden carbon dusts, is characterized in that sound is little, and safety coefficient is little, and is inflammable; The 2nd, explosive quality: inner core is to be mixed with potassium nitrate and male sulphur, be characterized in that sound is big, inflammable and explosive fried, even single setting off, the report of also wound the people sometimes is absolutely unsafe, and also having a kind of is toy-type: promptly make inner core material with red lead, Al-Mg alloy powder, cupric oxide, these firecrackers are safer relatively, but sound is too small, does not get consumer reception, the no market competitiveness.Above-mentioned all types of firecrackers structure all is paper web shells, shell one end earth back cover, and the centre is filled with powder shape inner core, and top refills the fuse shutoff, or fuse is located at the paper web sidepiece, and two ends all are to use the earth shutoff.The sound is single during the said structure firecracker setting-off, its production technology is numerous and diverse, pass through reel back cover, starching, solarization tube, medicine-feeding, closely knit, the operations such as deciding envelope, braided packing of pulling strings, production mostly is manual operations, not only production efficiency is low, and is absolutely unsafe, and especially makes up a prescription, shine medicine, medicine-feeding, technology danger such as closely knit is bigger, product in transportation, stored and deposited, part medicine core fuse becomes flexible and can not fire on the one hand, and is inflammable and explosive again on the other hand.

The purpose of this utility model is to provide a kind of sound big, and large, medium and small sound is alternate, and inner core under normal circumstances do not fire, not quick-fried, produces, transports, stores, sets off, equal safety; Simple in structure, easy production, the easy Firecrackers of technology.

The purpose of this utility model realizes by following technical proposals:

Stupid, the cupric oxide of inner core medicine red lead, the chlorine chloro of safety, magnesium powder and cement, PEF, alcohol, gelatine are made loud seed of vegetable seed to the soya bean size with making firecrackers, ring seed 0.05-0.5cm at interval, be distributed on the dimensional fabric bar, ring son and be provided with a fusee, ring sub wrapping up in and make cylindricality with fusee external application fabric, fabric is wrapped with 2-5 layer ply of paper, and ply of paper is wrapped with layer of polyethylene alcohol layer.

Can be filled with the fireworks powder for increasing fireworks effects, ringing between son, said fireworks powder is to be mixed by Al-Mg alloy powder, chlorine chlorobenzene powder, nitre sulphur saw foam powder and spices to constitute, and the each component proportion scale is decided as required, and its nitre sulphur saw foam powder is not less than 40%.

Ring the distribution of seed and decide as required, with big or small consecutive intervals, or several little interval one big sound seed are good.

Said fabric is that gauze or bonded fabric are good.

From above-mentioned situation as can be known the purpose of this utility model can realize.

Because of the sound of firecrackers very relevant with the tight ness rating of its inner core, the pine if the inner core medicine looses, then often do not produce the sound or sound spy is little, the sound that sprinkles that has only burning, if inner core is tight, moment generation detonation, then the sound is bigger, and the utility model is earlier inner core to be bonded into tight plastochondria with bonding cement, polyvinyl alcohol and gelatine agent, each plastochondria all sends clear and melodious sound when burning, and the sound is directly proportional with the sub-diameter of sound seed.Next is that the particle made with stick and inner core medicine is under normal condition, naked light does not fire, pound, hit not quick-fried, it has only by fuse and can light, so it is fool proof that transportation stores, its outer polyvinyl alcohol layer that is provided with makes the firecrackers body shrink on the one hand simultaneously, makes it tightr, can have moistureproof on the other hand.The used inner core medicine of the utility model all is the used medicines of toy firecrackers in addition, and is also fool proof when setting off.

Fig. 1 is a firecrackers configuration diagram of the present utility model.

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings below:

Embodiment 1

Stupid, the cupric oxide of inner core medicine red lead, the chlorine chloro of safety, magnesium powder and cement, gelatine and polyvinyl alcohol adhesive are made loud seed 1 of vegetable seed to the soya bean size with making firecrackers, ring seed 0.05-0.5cm at interval, be distributed on the fabric bar 2, ring son and be provided with a fusee 3, ring sub wrapping up in and make cylindricality with fusee external application fabric, fabric is wrapped with 2-5 layer ply of paper 4, and ply of paper is wrapped with layer of polyethylene alcohol layer 5.After said polyvinyl alcohol adds water earlier and is brewed into glue-like, again on the slurry.

Ring the distribution of seed and decide as required, with big or small consecutive intervals, or several big loud seed of several little intervals.Be filled with the fireworks powder for increasing the firework effect of firecrackers, ringing between son, said fireworks powder is to be made of Al-Mg alloy powder, chlorine chlorobenzene powder, nitre sulphur saw foam and spices mixed powder, and various powder ratios can be decided as required, and general nitre sulphur saw foam is no less than 40%.

Claims (3)

1, a kind of Firecrackers, it is characterized in that:, cupric oxide stupid by inner core medicine red lead, the chlorine chloro of making firecrackers safety, magnesium powder and binding agent cement, polyvinyl alcohol and gelatine are made loud seed (1) of vegetable seed to the soya bean size, be distributed on the dimensional fabric bar (2), ring son and be provided with a fusee (3), ring sub wrapping up in and make cylindricality with fusee outer fiber fabric, fabric is wrapped with 2-5 layer ply of paper (4), and ply of paper is wrapped with layer of polyethylene alcohol layer (5).

2, Firecrackers according to claim 1 is characterized in that: said fabric bar is that gauze or bonded fabric are good.

3, Firecrackers according to claim 1 is characterized in that: be filled with the fireworks powder between sound.
