Description

Pneumatic fireworks display

The utility model relates to a kind of cultural goods, particularly fireworks display.

Festivals or holidays and other celebrating date, people usually are to set off fireworks firecracker to show celebration in order to express happy mood.The firecracker of setting off fireworks not only easily goes out danger, and also contaminated air causes environmental pollution simultaneously, has prohibited the firecracker of setting off fireworks during festivals or holidays in recent years in big and medium-sized cities.But according to Chinese tradition, not putting fireworks and firecrackers makes the atmosphere in red-letter day not dense, in order to address this problem, people have done multiple effort, the technology that one key name is called " Confetti device " is disclosed for No. 96214561 as Chinese patent, a kind of fireworks display have been introduced, it has a hand tube, is with a balloon in hand tube upper port, and confetti is housed in the balloon, lower port at the hand tube has a cylinder base, the cylinder base downside has an air valve, and radially there is a pin-and-hole side, is inserted with latch in the hole, at the cylinder base upside spring is housed, at the spring upside colour bar tube is housed, in the colour bar tube colour bar is housed, be fixed with pricker at the colour bar tube end face of port, between the latch in pricker and the cylinder base pulling force rope is arranged, earlier in balloon, be full of air during use, pull out latch afterwards, pricker puncture balloon the colour bar tube is soared and on, spread the confetti paper slip that looses, form celebrating atmosphere.It is very high aerial that the weak point that this technology exists makes the air in the balloon that the colour bar tube rises to the sky not have enough power that the colour bar tube is pushed to after balloon is punctured, thereby do not have predetermined good result.

Task of the present utility model is to overcome the deficiencies in the prior art, and designing a kind of is the fireworks display that power drives the lift-off of lift-off tube with machinery and gas.

Task of the present utility model realizes as follows: fireworks display have a handgrip, and launching tube and lift-off tube are installed on the handgrip, in launching tube and the lift-off tube alkanes material are housed, and launching tube has sealing-locking device and emission switch.Lift-off tube part is equipped with colored vertically hung scroll, parachute and versicolor paper flower, paper scrap, paper slip etc.

Therefore the utility model does not have the sort of danger of fireworks and firecrackers because to adopt machinery and gas be that the power tube directive that will go up to the air is aerial, has a fireworks display function of spreading after the lift-off of lift-off tube, presents the fireworks display effect, can set off the atmosphere in red-letter day by contrast, expression people's happy mood.

Fig. 1 is a cutaway view of the present utility model;

A most preferred embodiment of the present utility model, as shown in Figure 1, dress parachute in the outsourcing tube 1, spring, paper flower, paper scrap, paper slip and vertically hung scroll 2 etc., launching tube 13 is installed on handgrip 14, in the emission cylinder base holddown spring 10 is housed, compaction plug 9, sealing ring 8 and sealing-plug 7 etc., on the launching tube 13 emitter is housed, emitter includes locking lever shaft 5, locking bearing pin 6, lock pin 11 and locking lever 12, in lift-off tube 3, alkanes material 4 is housed, the lift-off tube 3 outer parachutes that are surrounded by, spring, paper flower, paper scrap, connect together with lift-off tube 3 below paper slip and the vertically hung scroll 2 etc., vertically hung scroll.

The course of work of this device is: the operator hands handgrip, open the lock pin on the emitter, launching tube or the ejection at once of lift-off tube have the gas of pressure, the thrust of its high velocity air will go up to the air the tube directive aerial, after the lift-off tube rises up in the air, open under the parachute effect of spring in the above, the lift-off tube falls and hangs in the vertically hung scroll lower end after vertically hung scroll launched, and simultaneously multicoloured paper flower, paper scrap and paper slip etc. is sprinkled in the air.When using night, can be loaded with the effect that luminous or reflective material presents fireworks and firecrackers because of lift-off tube part.

Claims (1)
