Embodiment 1

[0033] In this embodiment, by arranging four fireworks display devices side by side, the effect of the specific pattern "SG50" is achieved when the fireworks are launched into the air. image 3 and Figure 4 .

[0034] figure 1 Only a firework launch tube is schematically inserted in the device, which can be understood by those skilled in the art. In general, the board of the device is filled with fireworks launching tubes. figure 1 The direction indicated by the middle arrow is the viewing direction of the fireworks pattern, which is the standing orientation of the viewer.

[0035] like figure 1 The components of the device were prepared as follows:

[0036] 1), first connect the base 31 and the base plate 23, the base is arranged on the ground plane, and the base plate is set at a certain angle to the horizontal plane; then the pole 32 is connected with the base 31 and the base plate 23, and the pole The plate surface angle adjustment part 321 (transverse through hole)...

Abstract

The invention provides a fireworks display device, which comprises a plurality of firework launch tubes, a launch tube angle fixing assembly and a bracket; the firework launch tube is a tube for setting fireworks products inside; the launch tube angle fixing assembly It includes a first board, a second board and a bottom board that are parallel to each other and are inclined relative to the horizontal plane and are arranged in sequence from top to bottom. The first board and the second board are each opened with a plurality of firework launchers. The through hole of the tube, and the contact end of the inserted firework launch tube can be in contact with the base plate. After a plurality of firework launch tubes are inserted into the launch tube angle fixing assembly, the pattern formed by the free end that is not in contact with the base plate is opposite. The pattern formed on its contact end is a similar pattern enlarged in size. The device provided by the invention has the advantages of safe discharge, accurate graphics, simple device and low cost. In particular, the device has the function of precise orientation of fireworks discharge, and the effect after discharge is highly consistent with the expected pattern.

Description

technical field [0001] The invention relates to the field of fireworks display, in particular to a fireworks display device and a fireworks display system. Background technique [0002] Some devices for setting off fireworks have been proposed in the prior art. For example, patent application CN201310414656 discloses a combined fireworks with subtitle pattern display function. The electronic light-emitting element is controlled by an open-circuit thermistor, and the open-circuit thermistor is connected to the combusting element of the combined firework to trigger; inside the shell, between the electronic light-emitting element and the shell shell, at least towards the top of the shell A light-shielding plate is provided in the direction of the face and / or side; at least one direction of the light-shielding plate is provided with a light-transmitting part hollowed out according to a preset subtitle pattern. This technical scheme realizes the function of displaying subtitle p...
