Description
Technical field
The utility model relates to a kind of Base for fireworks, refers in particular to a kind of easy to use and can improve the single-shot Base for fireworks of no gunpowder electric igniter of the prepackage belt lacing of igniting reliability and same effect.
Background technology
In firework display, except display shell, accurately setting off for setting off rhythm control of single-shot fireworks plays crucial effects.Because its igniting required precision is higher, manyly when setting off realize instantaneous ignition with directly the ignite mode of propellant powder of electric igniter.At present the plug into mode of electric igniter of single-shot fireworks mainly contains three kinds: first kind is by perforate on the fireworks barrel, the plug into working of plastics in room of the charged igniter head of packing into, straight-through propellant powder part.This method effect is the poorest, leaks outside in order to prevent propellant powder, and it is less to cross fire hole, easily stops up, and causes loss of ignition; Second kind is to preset the plug into plastic feet in room of charged igniter head, replaces bed mud to be contained in single-shot fireworks bottom, still need be in the corresponding base empty place punching of barrel.This method also has its shortcoming, and the one, the barrel drilling precision is had relatively high expectations, must be corresponding fully with position, hole on the base, the 2nd, the part propellant powder can fall into the electric igniter room, occupies certain space, causes electric igniter to be difficult to insert; The third is that the electric igniter room of plugging into is placed on the plastic feet of bottom, one through hole is arranged to the propellant powder part on the top, room of plugging into, and this method has guaranteed the integrality of barrel, still also has the too small problem of fire hole.
Owing to adopt the electric igniter igniting, current all single-shot fireworks igniting have the either large or small fire hole of crossing, when causing launching, emissivity all is not applied in the lift-off of effect parts, part strength is rushed down outward by crossing fire hole, the uniformity of lift-off height is difficult to guarantee that producer is many to remedy the corresponding danger that also increases this series products by increasing propellant powder content.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly makes in the lift-off that the propellant powder active force is used in the effect parts fully and safety coefficient prepackage belt lacing high, stable and reliable for performance, convenient to use does not have the single-shot Base for fireworks of gunpowder electric igniter.
In order to solve the problems of the technologies described above, the prepackage belt lacing that the utility model provides does not have the single-shot Base for fireworks of gunpowder electric igniter, comprise a circuit board and heating resistance wire, the plastic feet top is provided with circuit board slot, be provided with the groove that patches of a bottom of from described circuit board slot, leading to described plastic feet at described plastic feet, described circuit board is provided with two row's pins, the two ends of described heating resistance wire are electrically connected with two described row's pins respectively, described circuit board be fixed in the described circuit board slot and described heating resistance wire up, two described row's pins are positioned described patching in the groove down.
The top of described plastic feet is the bowl-shape of peripheral height, the middle end, and described circuit board is fixed in the circuit board slot of bowl-shape bottom.
The bowl-shape edge of described plastic feet leaves the lead-in wire breach.
The bottom margin of described plastic feet has the lead fixed screens.
Reinforcement is arranged at the bottom of described plastic feet.
The sidewall of described plastic feet is provided with sawtooth.
Described heating resistance wire is the good spiral resistance wire of electric heating transfer capability.
Be covered with parent's weldering coat of metal at described heating resistance wire, reach reliable welding and protective effect.
Described heating resistance wire is coated with one deck anti-oxidation protection film, and described anti-oxidation protection film is fixed on described heating resistance wire on the described circuit board.
The prepackage belt lacing of employing technique scheme does not have the single-shot Base for fireworks of gunpowder electric igniter, by applying one deck anti-oxidation protection film resistance wire is fixed on the circuit board, can prevent effectively that resistance wire from directly contacting with gunpowder, and itself as thin as a wafer and be easy to burning, can not influence the ignition performance of resistance wire; The anti-oxidation protection film on circuit board, makes it possess certain structure the resistance wire secure attachment, can resist and slightly the hanging of propellant powder.The plastic feet top is the bowl structure at the end between senior middle school on every side, and circuit board slot is positioned at center bottom.When inserting propellant powder, propellant powder can accumulate in the bowl, effectively contacts with heating resistance wire on the circuit board that is positioned at center bottom, and bowl structure is conducive to emissivity and concentrates to central authorities simultaneously, reaches better lift-off highly.Have one to patch groove and lead to the bottom in the circuit board slot of plastic feet, the circuit board that has welded heating resistance wire and row's pin is placed in the circuit board slot, and wherein heating wire faces up, and two row's pins are fixed on down and patch in the groove.Also will patch the groove sealing by gluing fixing circuit board.Reinforcement is arranged at the bowl-shape bottom of plastic feet, improves the structural behaviour of plastic feet with the cell wall that patches groove.The bottom margin of plastic feet has a lead fixed screens, and after row's adapter of circuit board on the plug on the lead and the plastic feet patched, lead can be fixed in this screens, in case plug is come off by external force.The edge of plastic feet bowl structure has a lead-in wire breach, is convenient to accurately insert lead-in wire on the single-shot fireworks that assemble in propellant powder, and realization as the igniting entrance, is extended to single fireworks or potted flower with current fireworks.The sidewall of plastic feet is provided with many little sawtooth, when increasing assembling and fireworks to the gluing contact area of wall.
During assembling, the sidewall of plastic feet that the no gunpowder electric igniter of belt lacing is housed is in advance applied glue, be inserted in the fireworks launching tube, insert propellant powder, the isolation scraps of paper with holes, effect parts and the sealing scraps of paper then according to the order of sequence and get final product.
During use, lead is inserted the groove that patches of two last hole Du Pont plugs along plastic bottom dress bottom, effectively contacts with two row's pins, and with lead to being fixed in the lead fixed screens, the right other end of lead is linked in the ignition installation.When setting off, to being conducting on the heating resistance wire and the moment heating, electric current ignites propellant powder by lead.
Compare with traditional single-shot fireworks, the utility model only needs the propellant powder of half can reach same firing altitude, and is stable and reliable for performance; The no gunpowder electric igniter that presets is without any hazard component, can not produce the false triggering phenomenon because of friction, bump, guaranteed that this utility model is produced, storage, transportation and use in security; Lead and plug are reusable, improve resource utilization, reduce use cost.
In sum, the utility model is a kind ofly to make in the lift-off that the propellant powder active force is used in the effect parts fully and safety coefficient prepackage belt lacing high, stable and reliable for performance, convenient to use does not have the single-shot Base for fireworks of gunpowder electric igniter.
