Abstract

The invention relates to the field of fireworks, in particular to a firework shell structure which comprises an elastic outer ring, wherein a weight part is arranged on an elastic outer ring body, a supporting strip is arranged inside the elastic outer ring body, and a pattern layer for displaying patterns is arranged at the upper part of the supporting strip.

Description

Firework shell structure

Technical Field

The invention relates to the field of fireworks, in particular to a firework shell structure.

Background

In the current fireworks technology, fireworks and crackers are classified into the following 5 types according to the structure of the fireworks and crackers and the motion form after being set off, including: spraying flowers: products mainly comprising flame spraying and spark spraying during setting off; and (3) rotation: the main body rotates and does not lift off when the product is set off; lifting: the main body is directionally lifted off when the product is set off; rotary lifting type: products which rotate and lift off by themselves when being set off; bead spitting: when the product is set off, several coloured beads, coloured flowers and sound can be regularly emitted from same cylinder body.

The fireworks show the expression forms of characters, patterns and the like after rising to the air, and only the following methods are available at present: firstly, dozens of candles and dozens of firework tubes are placed underground according to a preset pattern and then are ignited together, so that the candles and the firework tubes can be burnt for a long time, and patterns are kept by using fire light all the time; secondly, binding dozens of firework cylinders of hundreds on a bamboo shed according to a preset pattern, binding an iron wire net, then igniting the firework cylinders together, and burning for a long time to keep patterns by using fire light all the time; thirdly, a row of barrels is prepared by a firing company, is programmed in advance, a row of fireworks with timing delay fuses are fired for the day, are exploded at each position of a plane at the same time, and flash is emitted according to a preset dot matrix and is passed by one; fourth, only very simple graphics can be flashed in the air unstably. The firing company is engaged to build a cavity in the display shell and fry some solidified and bonded gunpowder balls (bright beads) to unstable positions. Repeated dozens of actual tests are required in advance, and the aerial distribution state still cannot be mastered finally, so that no good method exists abroad; fifthly, before 2010, the unmanned small aircraft capable of self-navigation is used for marshalling and accurately marshalling to fly to generate dynamic aerial images, firstly, the dynamic aerial images are realized indoors by means of stereo camera equipment and an image processing algorithm, then core devices are carried, and the aerial marshalling flying is carried out outdoors, wherein the carried high-performance core devices are not localized, and the algorithm is excellent; sixthly, projecting the image to an outer wall or a screen by using a small or large projector, wherein the screen can be a waterfall curtain wall and can be a smoke wall; seventhly, one or a roll of traditional paper scroll is exploded, and subtitles are printed on the scroll, so that the scroll is reliable, safe and stable, but the aerial effect is poor, and the observation effect difference at different angles is large; eighth, the scattering of the bulk powder into the pattern image is generally an ideal effect image drawn by a computer, and cannot be realized accurately in practice, so that the problem that the continuous stable space distribution of the modeling and the caption is generated and the continuous light emission is difficult to solve is really solved.

Disclosure of Invention

The invention aims to overcome the technical defects and provide a firework shell structure.

In order to solve the technical problem, the technical scheme provided by the invention is a firework shell structure which comprises an elastic outer ring, wherein a weight part is arranged on an elastic outer ring body, a supporting strip is arranged inside the elastic outer ring body, and a pattern layer for displaying patterns is arranged at the upper part of the supporting strip.

As an improvement, the surface of the pattern layer is provided with a pattern consisting of combustible substances.

As a refinement, the pattern layer is a planar pattern.

As an improvement, the pattern layer is a three-dimensional pattern.

As an improvement, magnetic devices for maintaining the north and south directions of characters or patterns are arranged on two sides of the elastic outer ring body.

Compared with the prior art, the invention has the advantages that:

1. one firework shell can display one character or a pair of patterns, including a plane pattern and a three-dimensional pattern, and the formed characters and patterns are stable in the air and are not influenced by the weather;

2. the method is simple and easy to implement, and the cost is low;

3. the requirements of different users can be met, for example, fireworks can be fired in national celebration, and three-dimensional patterns such as dragon, phoenix and the like can be emitted.

Detailed Description

The following describes a firework shell structure in detail with reference to the accompanying drawings.

With reference to the attached drawings 1-2, the firework shell structure comprises an elastic outer ring 1, wherein a weight component 2 is arranged on the ring body of the elastic outer ring 1, a support bar 3 is arranged inside the elastic ring body, and a pattern layer 4 for displaying patterns is arranged on the upper portion of the support bar 3.

As a preferred embodiment of this embodiment, the surface of the pattern layer 4 is provided with a pattern composed of combustible substances.

As a preferred embodiment of this embodiment, the pattern layer 4 is a planar pattern.

As a preferred embodiment of this embodiment, the pattern layer 4 is a three-dimensional pattern.

As a preferred embodiment of this embodiment, magnetic devices 5 for maintaining the north and south directions of the characters or patterns are disposed on two sides of the ring body of the elastic outer ring 1.

When the firework display device is implemented specifically, the weight part 2 is arranged on the ring body of the elastic outer ring 1, the support bar 3 is arranged inside the elastic ring body, the pattern layer 4 for displaying patterns is arranged on the upper portion of the support bar 3, a firework shell is compressed into a firework launching tube, then the firework shell is launched to a preset high altitude by igniting gunpowder or high-pressure air, and the pattern layer 4 is unfolded under the elastic action of the elastic outer ring 1.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
