Abstract

The utility model discloses a sealed firework launching tube, wherein a tube body is provided with an open upper port and a closed lower port; the closed lower port is provided with a fire transmission hole sleeve in the middle, a fire initiator is arranged in the fire transmission hole sleeve and sealed and fixed by glue, and the open upper port is closed after the propellant powder is filled into the inner cavity of the tube body from the upper port. The tube body restrains gunpowder gas generated by burning and exploding the propellant powder in the tube body, and the gunpowder gas can only burst through the upper end opening, is sealed, is upwards discharged out of the energy lifting effect piece and is launched and lifted from the outer barrel. The propellant powder can effectively avoid the loss of the propellant energy, reduce and standardize the dosage of the propellant powder, and the dosage is only one of twenty parts of the traditional propellant powder under the same working condition. Moisture-proof, little vibration, little smoke, no dust, safety and environmental protection. The device can be operated in a large workshop, reduces the labor cost, is convenient to operate, and has more advantages when being used for export products with limited dosage.

Description

Sealed firework launching tube

Technical Field

The utility model relates to a firework component, in particular to a launching tube.

Background

Among the prior art, fireworks urceolus bottom seals with the muddy bottom, and urceolus inner chamber bottom directly loads the propellant powder, covers the isolation layer on the propellant powder (if the paper ba nested in the urceolus inner chamber), device effect spare on the isolation layer, and the urceolus side punches and inserts the fuse to connect the ignition lead.

The main disadvantages are that the combustion cavity for emitting the propellant cannot be sealed, which leads to waste of work energy of combustion gas, overlarge amount of the propellant to be filled, overlarge smoke generated by combustion of the propellant and environmental pollution; meanwhile, the defects of complex processing technology and low production efficiency exist.

SUMMERY OF THE UTILITY MODEL

In order to solve the above disadvantages, the present invention provides a launching tube for fireworks, which can effectively utilize the explosion energy of the propellant powder. In order to solve the technical problems, the technical scheme adopted by the utility model is that the sealed firework launching tube comprises a tube body and is characterized in that the tube body is provided with an open upper port and a closed lower port; the closed lower port is provided with a fire transmission hole sleeve in the middle, a fire initiator is arranged in the fire transmission hole sleeve and sealed and fixed by glue, and the open upper port is closed after the propellant powder is filled into the inner cavity of the tube body from the upper port.

When the firework display device is used, the transmitting tube is arranged at the bottom of the inner cavity of the outer firework cylinder, the transmitting tube is covered with the isolation layer, and the isolation layer is provided with the effect piece. The firework effect piece launching device is used for launching firework effect pieces, such as firework inner cylinders, explosive columns, bright bead flower bundles, smoke, cockles, smoke bombs, signal bombs and other firework effect pieces, and can be used for single-shot or multi-shot combination.

The shape of the pipe body can be round pipe, square pipe, prism and other pipe bodies with various diameter specifications, and the pipe body can be provided with an outer sleeve. The upper port can be sealed by adhesive tape, gummed paper, cloth, fixing agent, soil, adhesive, jacket, etc.

The said kindling material can be ignited and launched by adopting fuse, kindling agent, electronic ignition head, etc.

The propellant can be white powder, black powder, sulfur-free propellant, and the like, and can be charged by a dry method or a wet method.

The utility model has the advantages that the tube body restrains gunpowder gas generated by burning and exploding the propellant powder in the tube body, the gunpowder gas can only burst through the upper end opening and is sealed, the energy lifting effect part is discharged upwards, and the energy lifting effect part is launched and lifted from the outer barrel. The propellant powder can effectively avoid the loss of the propellant energy, reduce and standardize the dosage of the propellant powder, and the dosage is only one of twenty parts of the traditional propellant powder under the same working condition. Moisture-proof, little vibration, little smoke, no dust, safety and environmental protection. The device can be operated in a large workshop, reduces the labor cost, is convenient to operate, and has more advantages when being used for export products with limited dosage.

The utility model is further described with reference to the following figures and detailed description.

Drawings

FIG. 1 is a schematic view of an external structure of a transmitting tube;

FIG. 2 is a schematic view of the internal cross-section of the launch tube;

fig. 3 is a schematic diagram of the structure of the launching tube.

Detailed Description

Referring to the attached drawings, reflecting a specific structure of the utility model, the sealed firework launching tube comprises a tube body 1, wherein the tube body 1 is provided with an open upper port 3 and a closed lower port 4; the closed lower port 4 is provided with a fire hole sleeve 7 in the middle, a fire primer, namely a fire lead 6 is arranged in the fire hole sleeve 7 and is sealed and fixed by glue, and the upper port 3 which is closed and opened by the adhesive plaster 2 is filled with propellant 5 from the upper port 3 to the inner cavity of the tube body.

In use, the transmitting tube is arranged at the bottom of the inner cavity of the firework outer barrel 8, the transmitting tube is covered with an isolation layer 10, and an effect piece (not shown in the figure) is arranged on the isolation layer 10. The ignition lead 6 is connected with the ignition lead 9. After ignition, the tube body 1 restrains gunpowder gas generated by burning and exploding the propellant powder 5 in the tube body from only bursting the seal of the adhesive plaster 2 from the upper port 3 to discharge energy upwards, and the propellant powder gas is lifted from the outer cylinder 8 through the isolation layer 10.

The above-mentioned implementation is only for clearly illustrating the technical solutions of the present invention, and is not to be construed as limiting the present invention in any way. The present invention has many known alternatives and modifications in the art, which fall within the scope of the present invention without departing from the spirit of the present invention.
