Dynamic flower-shaped firework setting-off appliance

Abstract

The invention discloses a dynamic flower-shaped firework setting-off appliance. The dynamic flower-shaped firework setting-off appliance comprises a plurality of petal body parts for mounting fireworks and also comprises a screw part connected with a rotation driving mechanism; a front substrate and a rear substrate are axially arranged along the screw part; a root part of each petal body part isarticulated on the front substrate; a middle part of each pedal body part is articulated with one end of a connection rod part, and the other end of the connection rod part is articulated on the rearsubstrate; the screw part is used for driving the substrates to do forward-backward linear motion along the axial direction of the screw part so as to shorten an axial gap between the front substrateand the rear substrate, so that a firework shape with flowers which gradually bloom can be formed. According to the dynamic flower-shaped firework setting-off appliance, a screw driving manner is usedfor achieving a process of dynamically opening and closing the flower shape of the fireworks; the appliance is reliable and lasting in operation and convenient to mount and use, and can be used repeatedly; the dynamic flower blooming process speed can be controlled to be perfectly matched with setting-off rhythm, background music and firework body effect; the smoke is reduced; the setting-off safety is improved.

Description

technical field [0001] The invention relates to a firework setting off appliance. Background technique [0002] The fireworks display is arranged through the combination of various fireworks products, pursuing a variety of display effects. However, in the prior art, fireworks display mostly focuses on the use of the static discharge effect of the fireworks body. By gathering a number of fireworks and discharging them sequentially, the choreography work is limited to the spatial layout and timing design of fireworks at fixed positions, which lacks dynamics and limits Its means of expression and form limit the innovation of fireworks display effects. [0003] Simultaneously, with regard to existing set-off apparatus, as the utility model patent document that authorization announcement number is CN28722Y discloses " dynamic firework ignition device ", authorization announcement number is that the utility model patent document disclosure of CN 206862217U " a combination "Firew...

However, in the prior art, fireworks display mostly focuses on the utilization of the static discharge effect of the fireworks body. By gathering a number of fireworks and discharging them sequentially, the choreography work is limited to the spatial layout and discharge timing design of fixed-position fireworks, which lacks dynamics and limits Its means and form of expression limit the innovation of fireworks display effects

[0003] Simultaneously, as far as the existing setting-off apparatus is concerned, as the utility model patent document with the authorized announcement number CN28722Y discloses the "dynamic fireworks lighting device", the utility model patent document with the authorized announcement number CN 206862217U discloses "a combined "Fireworks display frame" and so on, the dynamic effect is mostly achieved by rotating the platform, the effect is single, lack of innovation; and the drive of the existing dynamic fireworks is mostly driven by the injection power of pyrotechnic powder, but it is easy to cause too much smoke to affect the main display effect. , while the drive is unreliable and there are many safety hazards
