Abstract
The utility model discloses an outer tube body of combined fireworks, wherein the tube body is moulded by heat press, and comprises at least one explosive hole for containing firework explosives and at least one lead wire hole from which a lead wire penetrates; each bottom end of the various explosive holes is provided with a blind hole, and each bottom plate of the explosive holes is provided with the at least one lead wire hole; and at least two through holes which are symmetrical corresponding to the centerline of the tube body are arranged on the entire tube body of the combined fireworks. Since the outer tube body of the combined fireworks is moulded by heat press, the shape of the outer tube body and the arrangement of the explosive holes can be optionally designed depending on the demands of the users. The fireworks explosives with a whistling effect or with a lead wire can be arranged in the through hole, so that the effect is more abundant to set off the fireworks; in addition, through the through hole, the total mass of the tube body is reduced on one hand and a heat effect deformation while setting off the fireworks is lowered on the other hand, and the service life of the tube body is prolonged; and the safety of an erecting shelf is improved when the tube bodies are combined to form large fireworks.
Description
Technical field
The utility model relates to a kind of environment-friendly materials combined firework outer cylinder body.
Background technology
The original single combined firework launching tube by the paper moulding of the hot-forming replacement of patrix more and more came into one's own after utilization comprised the material mixings such as paper pulp, the broken end of phyteral, mineral stone flour and glue at present, so just require this new material combined firework outer cylinder body lower than original paper launching tube production cost, and production efficiency will improve, because it is hot-forming that this kind new material is formulated arts demand, the rear stability that requires to be heated is strong and weight is lighter than paper launching tube.And there is following defective in this combined firework outer cylinder body of prior art: weight is heavier, increases the cost of setting up of cost of transportation and support, when setting off the thermal deformation of cylindrical shell larger, dangerous, service life is short.
The utility model content
The purpose of this utility model is to provide a kind of lightweight, fuel factor stable, firework display effect is abundant environment-friendly materials combined firework outer cylinder body.
This combined firework outer cylinder body that the utility model provides, hot-forming by the mixture patrix behind paper pulp, the broken end of phyteral, mineral stone flour and the glue mixing, has some medicines hole, the bottom in each medicine hole is blind hole, has a fairlead on its base plate at least, have two on this outer cylinder body at least about the through hole of cylindrical shell center line symmetry, can guarantee that so whole outer cylinder body is heated evenly.
The aperture of described through hole is less than the aperture in described medicine hole.
Through hole more than two is arranged on the utility model outer cylinder body, can place the effect of blowing a whistle or the fireworks medicine of being with lead-in wire in the through hole, like this so that during firework display effect abundanter, in addition, the setting of this through hole, alleviated on the one hand the gross mass of cylindrical shell, reduce cost of transportation, the fuel factor distortion in the time of reducing firework display on the other hand prolongs its service life, when being combined into large-scale fireworks with this cylindrical shell, also can improve the security that it sets up frame.Because the utility model is hot-forming, so the arrangement in its shape and medicine hole can design arbitrarily according to user's needs.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation of looking up of Fig. 1.
The specific embodiment
Can find out that from Fig. 1-Fig. 3 this combined firework outer cylinder body that the utility model provides is through hot-forming, it has at least one medicine hole 1 that is used for dress fireworks medicine, at least one is used for connecting the fairlead 2 of line.Shape of the present utility model is to design arbitrarily by user's requirement, can also utilize some basic configurations to go to form some other shapes.What diagram provided is rectangle side's body, its medicine hole 1 has several, they are matrix arranges, and is blind hole, and a fairlead 2 is arranged on the base plate in last medicine hole 1, two fairleads 2 are all arranged on the base plate in other each medicine hole, one is used for lighting of lead-in wire and this medicine hole fireworks medicine, and another is used for lead-in wire transmission, has two on this outer cylinder body at least about the through hole 3 of cylindrical shell center line symmetry, the aperture of through hole 3 is less than the aperture in medicine hole 1, leaded holddown groove 4 on the outer wall of cylindrical shell.This shape can go to form the shapes such as triangular prism polygon prism with some.
During connecting lead wire, note successively lead-in wire being passed the fairlead 2 of each 1 bottom, medicine hole, and between the two adjacent medicine holes 1 continuous lead-in wire is arranged, guarantee that the fireworks medicine in each medicine hole 1 is sequentially seted off, at last lead-in wire is fixed in the lead-in wire holddown groove 4 on the cylinder body outer wall.
Claims (2)
1. combined firework outer cylinder body, this cylindrical shell has some medicines hole, and the bottom in each medicine hole is blind hole, has a fairlead on its base plate at least, it is characterized in that: have two on this cylindrical shell at least about the through hole of cylindrical shell center line symmetry.
2. combined firework outer cylinder body according to claim 1, it is characterized in that: the aperture of described through hole is less than the aperture in described medicine hole.
