Abstract

A novel combined firework including several columnar firework canisters connected by a bus fuse; substratum, a solid filling room and firework bombs provided at the outside column of each firework canister from bottom to top is characterized in that bomb canister of the firework has an inner canister; between the bomb canister and the inner canister is filled with sealing stuff; the upside and the downside surface of the bomb canister are stuck with slips; in the inner canister are provided with substratum, shining beads detonator layer and solid fuze from bottom to top; one end of down-lead enters into the shining beads detonator layer through the solid fuze layer, the other end into the solid filling room through the sealing stuff. The utility model has the advantages as follows: 1. the down-lead is provided from bottom to top with bigger length and delay time, so that it could guarantee the rising height of the firework and minish the thickness and weight of the substratum, thereby decreasing the solid filling quantity; 2. the bus fuse makes the combined firework more safety; the canister wall of the solid filling room without fuse hole makes it more tightly.

Description

A kind of novel combined firework

Technical field

The utility model relates to firework product, promptly a kind of novel combined firework.

Background technology

Traditional combined firework, the fireworks tube that comprises several cylinders shape, each fireworks tube is substratum 1 from bottom to top successively, emission coyote hole 2, the following scraps of paper 3, the firework bomb 4 and the last scraps of paper 5, firework bomb 4 is fire insulation mud 6 from bottom to top, bright pearl explosive layer 7 and sealing compound 8,9 upper ends that go between are passed fire insulation mud 6 and are stretched into bright pearl explosive layer 7, the lower end is stretched in the propellant powder, a blasting fuse 10 connects two adjacent fireworks tubes, the two ends of blasting fuse 10 are stretched in the propellant powder of two adjacent fireworks tubes, link to each other in twos, whole fireworks tubes all are chained together, as shown in Figure 1, fill clay powder in the traditional combined firework substratum 1.

This structure has following shortcoming: 1, in order to guarantee that firework bomb 1 has certain rise time, lead-in wire just requires certain length, has so just increased the thickness and the weight of fire insulation mud 6, has increased the consumption of propellant powder; 2, blasting fuse 10 has been worn two holes to the propellant powder layer 2 of each fireworks tube, has reduced emissivity, and fireworks tube all fireworks tubes that will influence thereafter that miss-fire miss-fire; 3, the scraps of paper 3 are placed on above the propellant powder 2 down, and often the scraps of paper are put not just, make emission coyote hole poor sealing, make the emission of cigarette medicine bullet not high, even do not launch, and propellant powder 2 breaks through fire insulation mud 6 sometimes, causes fried tube; 4, in the substratum 1, clay powder is too dried, and the substratum intensity difference is if the clay humidity then can make propellant powder 2 make moist.

Summary of the invention

For overcome too thick too heavy, the emission coyote hole gas leakage imprecision of conventional combination fireworks fire insulation mud, the scraps of paper are put shortcomings such as deflection easily, the utility model proposes a kind of design of novel combined firework.

This novel combined firework, the fireworks tube that comprises several cylinders shape, with a total blasting fuse they are connected together, in the urceolus of each fireworks tube, be substratum, emission coyote hole and firework bomb from bottom to top, it is characterized in that, an inner core is arranged in the cylinder of firework bomb, be filled with sealing compound between cylinder and the inner core, the upper and lower plane of cylinder is pasted with the scraps of paper, from bottom to top for playing substratum, bright pearl explosive layer and solid flashing composition, the end that goes between passes the solid flashing composition layer and enters bright pearl explosive layer in the inner core, and the other end enters the emission coyote hole through sealing compound downwards.

Total blasting fuse passes from the space of substratum bottom, and blasting fuse one end of each fireworks tube is upward through substratum and enters the emission coyote hole, and the other end and total blasting fuse stick together.

The filler of substratum is the mixture of clay powder and hydrated lime in powder.

The utility model has following advantage: 1, lead-in wire from top to bottom has bigger length and delay time, can guarantee the height that firework bomb rises, and reduces the thickness and the weight of substratum, thereby reduces the emission dose.2, to make combined firework set off more reliable for total blasting fuse, and the barrel of emission coyote hole is not worn blasting fuse hole, better tightness.3, cement the scraps of paper below the cylinder, can guarantee that cylinder puts just, the emission coyote hole is more sealed.4, add hydrated lime in powder in the substratum after, make subsoil drier, intensity is higher.

Description of drawings

Fig. 1 is a conventional combination fireworks fireworks tube cutaway view

Fig. 2 is the utility model fireworks tube cutaway view

Among the figure: 1, substratum, 2, the emission coyote hole, 3, the following scraps of paper, 4, firework bomb, 5, go up the scraps of paper, 6, fire insulation mud, 7, bright pearl explosive layer, 8, sealing compound, 9, lead-in wire, 10, blasting fuse, 11, total blasting fuse, 12, inner core, 13, solid flashing composition, 14, play substratum.

The specific embodiment

Details are as follows to the specific embodiment of the present utility model below in conjunction with Fig. 2:

Be substratum 1, emission coyote hole 2 and firework bomb 4 from bottom to top in the urceolus of fireworks tube, an inner core 12 is arranged in the cylinder of firework bomb 4, be filled with sealing compound 8 between cylinder and the inner core 12, the plane is pasted with circular paper 5 on the cylinder, and lower plane is pasted with circular paper 3, in the inner core 12, from bottom to top for playing substratum 14, bright pearl explosive layer 7 and

solid flashing composition

13,9 one ends that go between pass solid flashing composition 13 and enter bright pearl explosive layer 7, and the other end enters emission coyote hole 2 through sealing compound 8 downwards.

Total blasting fuse 11 passes from the space of substratum 1 bottom, and blasting fuse 10 1 ends of each fireworks tube are upward through substratum 1 and enter emission coyote hole 2, and the other end and total blasting fuse 11 stick together.

The filler of substratum 1 is the mixture of the hydrated lime in powder of the clay powder of 3/4 weight and 1/4 weight.

Claims

1, a kind of novel combined firework, the fireworks tube that comprises several cylinders shape, with a total blasting fuse they are connected together, in the urceolus of each fireworks tube, be substratum, emission coyote hole and firework bomb from bottom to top, it is characterized in that, an inner core is arranged in the cylinder of firework bomb, be filled with sealing compound between cylinder and the inner core, the upper and lower plane of cylinder is pasted with the scraps of paper, from bottom to top for playing substratum, bright pearl explosive layer and solid flashing composition, the end that goes between passes the solid flashing composition layer and enters bright pearl explosive layer in the inner core, and the other end enters the emission coyote hole through sealing compound downwards.

2, combined firework according to claim 1 is characterized in that, total blasting fuse passes from the space of substratum bottom, and blasting fuse one end of each fireworks tube is upward through substratum and enters the emission coyote hole, and the other end and total blasting fuse stick together.
