Abstract

The utility model relates to a combined fireworks firecracker which comprises 7 to 200 launching cylinders, and a general fuse is connected with all launching cylinders; the combined fireworks firecracker is characterized in that the launching cylinder is columniform, each launching cylinder is composed of a bottom soil layer, a launching powder, a paper, a firecracker layer and an air section in turn from bottom to top, the firecracker layer is provided with 3 to 15 firecrackers closely and horizontally arranged on the paper, each firecracker is composed of a fixed ignition layer, an explosive layer and a sealing layer in turn from bottom to top, the fixed ignition layer is provided with an ignition harness, one end of the ignition harness is exposed out of the fixed ignition layer and stuck on the paper and its other end stretches into the explosive layer. The utility model has the following advantages: 1. The paper cylinder with the diameter less than 6.5mm can be used to make firecrackers, which can save explosives and various materials; 2. Reducing the knitting working procedures, saving the ignition harness; 3 The general fuse of high burning rate can't be used in order to make the production and discharge safer; 4. The flute voice and the color ball can be added, which has the double effect of the fireworks and firecrackers; 5. The launching cylinder can be recycled.

Description

A kind of Combined fireworks and fire crackers

Technical field

The utility model relates to fireworks and firecrackers, promptly a kind of Combined fireworks and fire crackers.

Background technology

Fireworks, firecracker is as the traditional product of China, its sound is loud and clear, shine brilliant, lucuriant in design, it is lucky and be loved by the people to increase celebrating lively atmosphere and implied meaning, by national standard, firecracker is divided into A level and B level two classes, the powder charge of A level firecracker is less, sound is less, B level firecracker sound rings, volume is big, more get consumer reception, its single diameter is more than 8.5mm, and whole extension firecracker packaging volume is bigger, when setting off, open also long, general production method to be the system cake, powder charge, insert and draw, seal, woollen yarn knitting and packing, its major defect has: 1, the firecracker diameter is bigger, dose, paper amount and other material usages are all big, have increased the difficulty and the degree of danger of producing; 2, because B level firecracker explosive payload is bigger, must use the very fast total blasting fuse of combustion speed, to guarantee not cutoff midway, this has just increased the degree of danger that blasting fuse, firecracker are produced greatly, and when the consumer sets off, hide easily not as good as and damage, be subjected to the influence of blasting fuse quality, the firecracker finished product is easy to occur cutoff or the too fast problem of hurting sb.'s feelings of combustion speed.。

Summary of the invention

B level firecracker dose is big, raw materials consumption is high and the fast shortcoming of total blasting fuse combustion speed in order to overcome, and the utility model proposes a kind of new design of Combined fireworks and fire crackers.

This Combined fireworks and fire crackers, form by 7～200 launching tubes, a total blasting fuse links together whole launching tubes, it is characterized in that, launching tube is cylindrical, in each launching tube, be followed successively by substratum, propellant powder, the scraps of paper, firecracker layer and air section from bottom to up, 3～15 tight, parallel standing up on the scraps of paper of firecracker are arranged in the firecracker layer, each firecracker is followed successively by from bottom to up and draws layer, explosive layer and tight mouthful of layer admittedly, admittedly draw fuse is arranged in the layer, and fuse one end exposes and draws admittedly outside the layer, be attached on the scraps of paper, the other end stretches in the explosive layer.

In the launching tube upper surface of substratum be around the low sphere shape in high center, total blasting fuse passes from the diameter of launching tube cross section, in cross circular section, total blasting fuse two ends are in substratum, always the blasting fuse stage casing is in propellant powder.

In the firecracker layer, can place sibilant rale.

In propellant powder, can place the look bullet.

When setting off, light total blasting fuse exposed junction, total blasting fuse is lighted each launching tube successively, after propellant powder in the launching tube is lighted, firecracker is thrown in the air, and the firecracker in each launching tube is blast continuously successively aloft, like this, the acoustics of existing firecracker has skyborne light of fireworks and color again.

The utility model has the advantages that: 1, can use diameter to make firecracker less than the paper web below 6.5 millimeters, not only reduce paper and material usage, and reduced explosive charge, but strengthened effects,sound, because firecracker paper cake cumulative volume reduces, reduce the production difficulty, improved safety coefficient and production efficiency; 2, the utility model makes whole firecracker production link reduce the operation of woollen yarn knitting, so both can save 60% fuse, can draw operation and mentions before the powder charge inserting again, improves production safety greatly; 3, because the method that total blasting fuse of the form of use combined firework and the utility model design is connected, total blasting fuse that entire product is no longer accelerated with combustion speed when ensuring the quality of products, so both reduced the dangerous coefficient produced more guarantee product quality, satisfy the demand of market comsupton simultaneously; 4, in the firecracker assembling, can add kinds such as sibilant rale and look bullet, more increase the firecracker firework display effect; 5, can recycle launching tube, save resource.

The specific embodiment

Below in conjunction with accompanying drawing, details are as follows to the specific embodiment of the present utility model, among the figure 1, launching tube, 2, total blasting fuse, 3, substratum, 4, propellant powder, 5, the scraps of paper, 6, firecracker, 7, air section, 8, draw layer admittedly, 9, explosive layer, 10, tight mouthful of layer, 11, fuse, 12, sibilant rale, 13, the look bullet.

In Fig. 2, Combined fireworks and fire crackers is made up of 16 launching tubes 1, total blasting fuse 2 is cascaded these 16 launching tubes, launching tube 1 is cylindrical, in Fig. 1, in each launching tube 1, be followed successively by substratum 3 from bottom to up, propellant powder 4, the scraps of paper 5, firecracker 6 and air section 7 have 7 of firecrackers in each launching tube 1, firecracker 6 is tight, parallel stands up on the scraps of paper 5, each firecracker 6 is followed successively by from bottom to up and draws layer 8 admittedly, explosive layer 9, with tight mouthful of layer 10, admittedly draw in the layer 8 fuse 11 is arranged, fuse 11 1 ends expose and draw admittedly outside the layer 8, be attached on the scraps of paper 5, the other end stretches in the explosive layer 9, in the launching tube 1 upper surface of substratum 3 be around the low sphere shape in high center, always blasting fuse 2 passes from the diameter of launching tube 1 cross section, in cross circular section, total blasting fuse 2 two ends are in substratum 3, and total blasting fuse 2 stage casings are in propellant powder 4, in each launching tube 1, firecracker layer center is placed with 1 sibilant rale 12, in propellant powder 4, is placed with 1 look bullet 13.
