Abstract

The fireworks rocket disclosed by the utility model comprises at least a gun barrel, a down-lead and a balance lever. A holding room is formed in the gun barrel and an impelling powder layer and an effect powder layer are provided from top to bottom in the holding room. The down-lead is provided with an ignition end, a first extended burning end and a second extended burning end. The ignition end protrudes below the gun barrel and the first extended end is buried in the impelling powder layer and the second extended burning end is buried in the effect powder layer along outer side of the gun barrel. After the ignition end is ignited, the impelling powder layer and the effect powder layer will be ignited through the first extended burning end and the second extended burning end respectively so that the fireworks rocket can be impelled and rise upwards into the air and fireworks effect is shown. In addition, the effect powder layer is ignited after a time when the fireworks rocket is impelled into the air by controlling relative length of the first extended burning end and the second extended burning end or burning rate of the down-lead to show fireworks effect.

Description

The structural improvement of fireworks rocket

Technical field

The structural improvement of the relevant a kind of fireworks rocket of the utility model refers to a kind ofly can prolong the relative length or the lead-in wire burning velocity of burning end by first and second of control lead-in wire especially, and then control is toward raising in the air and the fireworks fire arrow structure improvement of the fireworks time difference of igniting.

Background technology

Whenever specific holiday or happy festival time all can be discharged pyrotechnics and cooperated with this great project, celebrate together to show, and dispensing pyrotechnics by the many fireworks of ground surface launching to day aerial, make it produce blast aloft, discharge beautiful fireworks.

As shown in Figures 1 and 2, general fireworks rocket 1 includes: a gun barrel 11, a lead-in wire 12 and one balancing pole 13, form an accommodation space 111 in this gun barrel 11, its accommodation space 111 from bottom to top is provided with a propulsive charge layer 112 and effect gunpowder layer 113 in regular turn, its 12 1 ends that go between stretch out gun barrel 11 belows, end then is embedded in this propulsive charge layer 112 in addition, and an end of balancing pole 13 then is fixed in the outer surface of gun barrel 11.

By this,, make 112 burning of propulsive charge layer, can drive this fireworks rocket 1 integral body in the air, burn totally, prolong again and burn, can produce the performance of firework effect to effect gunpowder layer 113 and work as propulsive charge layer 112 toward raising when a combustion wire 12; Yet, the time of the fireworks that ignite be treat that the propulsive charge grate firing burns totally in, that is this propulsive charge layer upwards raises the fireworks rocket to the summit, just there are fireworks to ignite, differing greatly of this time allows the audience will wait for the time more of a specified duration, just watched pyrotechnics.

The utility model content

In view of this, the utility model provides a kind of can prolong the relative length or the lead-in wire burning velocity of burning end by first and second of control lead-in wire, and then control is toward raising in the air and the fireworks fire arrow structure improvement of the fireworks time difference of igniting.

For reaching above-mentioned purpose, fireworks rocket of the present utility model includes at least: a gun barrel, a lead-in wire and a balancing pole; Wherein, form an accommodation space in this gun barrel, its accommodation space from bottom to top is provided with a propulsive charge layer and effect gunpowder layer in regular turn, and lead-in wire is provided with and lights end and first and second and prolong and burn end, it is lighted end and stretches out the gun barrel below, first elongated end then is embedded in this propulsive charge layer, second prolongs the burning end then is embedded in the effect gunpowder layer along the gun barrel outside, by lighting end points then, prolong to burn to hold via first and second respectively propulsive charge layer and effect gunpowder layer are lighted, make this fireworks rocket the performance of firework effect be arranged simultaneously in the air simultaneously toward raising.

The specific embodiment

The utility model " structural improvement of fireworks rocket ", the structure of its fireworks rocket is formed as shown in Figures 3 and 4, and this fireworks rocket 2 includes at least:

One gun barrel 21, form an accommodation space 211 in this gun barrel 21, its accommodation space 211 from bottom to top is provided with a grave mound layer 212, propulsive charge layer 213, grave mound layer 212, effect gunpowder layer 214 and grave mound layer 212 in regular turn, each grave mound layer 212 can be provided with a fairlead 215, and its grave mound layer 212 can also be cardboard.

One lead-in wire 22, this lead-in wire 22 is provided with to be lighted end 221 and first and second and prolongs and burn end 222,223, it is lighted end 221 and stretches out gun barrel 21 belows, first prolongs burning end 222 is arranged in the fairlead 215, and be embedded in this propulsive charge layer 213, second prolongs and burns end 223 then along gun barrel 21 outsides, and passes fairlead 215 and be embedded in the effect gunpowder layer 214.

One balancing pole 23, the one end is fixed in the outer surface of gun barrel 21.

By this, when lighting of a combustion wire holds 221, make first to prolong 222 burnings of burning end and make 112 burning of propulsive charge layer, it is whole toward raising in the air to drive this fireworks rocket 1, prolong simultaneously and burn end 223 and make 214 burning of effect gunpowder layer and light end 221 by second, make this fireworks rocket the performance of firework effect be arranged simultaneously in the air simultaneously toward raising.

Certainly, can first and second prolong the relative length or the lead-in wire burning velocity of burning end by control, and then control is toward raising in the air and igniting the fireworks time difference, as shown in Figure 5, second to prolong the length of burning end 223 longer for it, thus burn longer a period of times when propulsive charge layer 213, that is this fireworks rocket 2 is toward raising in the air to certain hour, just light this effect gunpowder layer 214, and produce the performance of firework effect; In addition, also can for example select different lead materials, make first and second prolong the burning velocity difference of burning end, control the fireworks rocket in the air toward raising and igniting the fireworks time difference by control lead-in wire burning velocity.

As mentioned above, the utility model provides a kind of structural improvement of fireworks rocket, so offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc., identical such as, all should belong to of the present utility model founding within purpose and the claim.
