Abstract
The utility model relates to a combined fireworks which comprises a plurality of fireworks cylinders; the outer cylinder of each fireworks cylinder is composed of a bottom layer, a powder launching layer, a display shell and an empty pipe section from bottom to top; the combined fireworks is characterized in that the combined fireworks is provided with a general ignition harness, one end of the ignition harness of each fireworks cylinder is connected with the general ignition harness in the outer part of the fireworks cylinder and its other end is inserted into the powder launching layer of the fireworks cylinder through a small hole in the fireworks cylinder wall. The utility model has the following advantages: 1. The general ignition harness is added besides the ignition harness, which makes the connection of each fireworks cylinder in the combined fireworks equal to the parallel connection in the circuit and greatly improves the stability and security of setting off the combined fireworks; 2. The bottom layer of the fireworks cylinder is a composite layer of the paper and dry soil, the composite layer of the paper and dry soil has the good strength, and thereby isn't easy to be damaged, and can make a plurality of recycled paper be used.
Description
Technical field
The utility model relates to firecrackers, the firework product in the daily life, promptly a kind of combined firework.
Background technology
Combined firework, because of its gorgeous fireworks display that go up to the air continuously, very popular.Combined firework is closely combined together by several fireworks tubes and forms, be bottom from bottom to top in the urceolus of each fireworks tube, the propellant powder layer, display shell and blank pipe section, there are two problems in combined firework in the market, the one, the fuse problem: fuse is several segments, insert respectively in the propellant powder of two adjacent fireworks tubes at the two ends of every section fuse, after a fireworks tube is lighted, just by fuse adjacent fireworks tube is lighted, so continuously whole combined firework is lighted successively, because the insertion position was improper when the mass defect of fuse or workman installed fuse, or owing to indivedual fireworks tube miso-fires often can not be lighted adjacent fireworks tube, thereby cause a plurality of fireworks tube miso-fires after this, form the safety problem of intractable, accidents happened easily.Two, bottom problem: the bottom of fireworks tube has two kinds of forms at present, and the one, to make with clay, its thickness is the diameter of nozzle, therefore thicker, weight is big, during filling, contain certain moisture content in the soil, done back native cake and shunk, be easy to Lou soil, damaged in transit, influence the quality and the safety of display shell, the 2nd, make with wooden unit, low weight, also cracky not, but consume a large amount of precious timbers, cost is higher.
Summary of the invention
In order to solve in the present combined firework the problems referred to above of igniting unstable and fireworks tube bottom, the utility model proposes the combined firework that a kind of new mode is arranged fuse, and proposed new design for the bottom of fireworks tube.
This combined firework, combine by several fireworks tubes, in the urceolus of each fireworks tube, be bottom, propellant powder layer, display shell and blank pipe section from bottom to top, it is characterized in that, a total fuse is arranged in the combined firework, and the outer total fuse of fuse one end of each fireworks tube and fireworks tube links to each other, and the other end passes in the propellant powder in the aperture insertion fireworks tube on the fireworks barrel.
Total fuse be furnished with two schemes: scheme one, total fuse is linked to be by the outer part of the tube of several segment fuse, insert in the propellant powder of two adjacent fireworks tubes at the two ends of each segment fuse.
Scheme two: the fuse of each fireworks tube is single two-fold, and two ends are passed aperture on the fireworks barrel together and inserted in the propellant powder in the fireworks tube, and total fuse is pasting the outer wall of fireworks tube, passes through from the bending part of the fuse of each fireworks tube.
The bottom of fireworks tube is made up of the dry ground layer on the bottom scraps of paper and the scraps of paper, and scraps of paper circumference and fireworks tube outer wall bond together.
Dried the thickness of the layer is half of fireworks tube external diameter.
The utility model has the advantages that: 1, set up total fuse outside the fuse, make the connection of each fireworks tube in the combined firework be equivalent to the parallel connection in the circuit, some fireworks tubes do not fire or the problem of a certain section fuse can not influence firing of backward other fireworks tubes, have improved stability and security that combined firework is seted off greatly; 2, the bottom of fireworks tube is the composite bed that the scraps of paper add dry ground, both avoided the weight of pure soil layer big, the shortcoming of cracky, avoided the high shortcoming of a large amount of timber costs of wooden bottom consumption again, paper-soil composite bottom layer intensity is good, cracky not, and a large amount of recycled writing papers is utilized.

The specific embodiment
As follows below in conjunction with accompanying drawing to specific embodiment enumeration of the present utility model: among the figure 1, urceolus, 2, the scraps of paper, 3, the dry ground layer, 4, the propellant powder layer, 5, display shell, 6, the blank pipe section, 7, total fuse, 8, fuse.
In Fig. 2,6 fireworks tubes closely combine together.
In Fig. 1, in the urceolus 1 of each fireworks tube, be the scraps of paper 2 from bottom to top, dry ground layer 3, propellant powder layer 4, display shell 5 and blank pipe section 6, the scheme that is arranged as two of total fuse, the fuse 8 of each fireworks tube is single two-fold, the aperture that two ends are passed on the wall of fireworks tube 1 together inserts in the propellant powder layer 4, the outer wall that total fuse 7 is pasting fireworks tube 1 passes through from the bending part of each fuse 8, in Fig. 1, the bottom of fireworks tube is made up of the dry ground layer 3 on the bottom scraps of paper 2 and the scraps of paper, the outer wall of the circumference of the scraps of paper 3 and fireworks tube 1 bonds together, and the thickness of dry ground layer 3 is half of external diameter of fireworks tube 1.
In Fig. 3, the scheme that is arranged as of total fuse, total fuse 7 is linked to be by the outer part of the tube of A-A, B-B, C-C, D-D, E-E, F-F, a G-G7 segment fuse, and the fuse 8 of each segment inserts in the propellant powder 4 of two adjacent fireworks tubes 1.
Claims (5)
