Abstract
The utility model discloses a firecracker. The firecracker comprises a box and the top of the box is provided with a hanging end. The firecracker is characterized by also comprising a plurality of explosive cylinders; the lower portion of the box is connected with an upper cover through a connecting wire; the upper cover is connected with tops of the explosive cylinders; the bottoms of the explosive cylinders are provided with mesh covers and cylinder bodies are provided with small holes; the internal wall of every explosive cylinder is provided with a blasting fuse; gunpowder particles are arranged beside the blasting fuses with intervals; external sides of the blasting fuses and gunpowder particles are provided with swelling sticking paper which are adhered to the internal wall of the explosive cylinders; the bottom of every blasting fuse penetrates the corresponding mesh cover to form into an ignition end. The firecracker has the advantages of being good in safety due to the fact that explosion which is limited to the interior of the explosive cylinders does not splash and damage people; being clean after setting off due to the fact that most comburent is limited inside the explosive cylinders through the mesh covers after setting off; being safe during the conveying or storage process due to the facts that the gunpowder content is small and the explosive cylinders are far from each other.
Description
Technical field
The utility model relates to a kind of firecrackers.
Background technology
Chinese celebrating the New Year or the Spring Festival, celebrate a festival, get married, the celebrating time such as opening all likes setting off firecrackers, and fills more gunpowder in existing firecrackers, during transportation security poor, just had the report of the quick-fried disconnected bridge of fireworks transfer cart blast last year; On the other hand, existing firecrackers explosion time is easily hurted sb.'s feelings, and explosion time security is poor, owing to there being such problem, so be necessary to invent the better firecrackers of a kind of security
Summary of the invention
The purpose of this utility model is the better firecrackers of a kind of security that design in order to solve the deficiency of above-mentioned technology.
A kind of firecrackers that the utility model is designed, comprise box body, and box body top is provided with suspended end, it is characterized in that also comprising several torpedo shells, and described box body bottom is connected with upper cover by connecting line, and upper cover is connected with the top of torpedo shell; Described torpedo shell, bottom is provided with square, and its stack shell is provided with aperture; On the inwall of torpedo shell, be provided with a blasting fuse, blasting fuse is other is interval with powder grain, and the outside of blasting fuse and powder grain is also provided with the paster that is crowned being bonded on torpedo shell inwall, and described blasting fuse bottom forms a firing tip through square.
As preferably:
Between described upper cover and the top of torpedo shell for removably connecting;
Described torpedo shell is surrounded by fire retardant outward;
In described box body, be provided with loudspeaker;
The firecrackers that the utility model is designed, it is inner that blast has been limited in torpedo shell, can not splash and hurt sb.'s feelings, and while setting off, security is better; Discharge rear most comburant and be limited in torpedo shell by square, more clean clean after discharging; And this firecrackers are in transportation or storing process, because gunpowder content is few and spaced far, safer, whole torpedo shell is easy to heat radiation, and in transportation, fricative heat is difficult for piling up, and is difficult for the phenomenon of blasting, and security is better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model torpedo shell;
Fig. 3 is the improved structural representation of the utility model torpedo shell;
Fig. 4 is the structural representation of the utility model another embodiment.
In figure: box body 1, suspended end 2, torpedo shell 3, connecting line 4, upper cover 5, square 6, aperture 7, blasting fuse 8, powder grain 9, paster 10, firing tip 11, fire retardant 12, loudspeaker 13.
The specific embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, 2, the described a kind of firecrackers of the present embodiment, comprise box body 1, box body 1 top is provided with suspended end 2, it is characterized in that also comprising several torpedo shells 3, described box body 1 bottom is connected with upper cover 5 by connecting line 4, and upper cover 5 is connected with the top of torpedo shell 3; Described torpedo shell 3, bottom is provided with square 6, and its stack shell is provided with aperture 7; Aperture 7 can be for entrant sound sound, also can enter air, on the inwall of torpedo shell 3, be provided with a blasting fuse 8, the other powder grain 9 that is interval with of blasting fuse 8, the outside of blasting fuse 8 and powder grain 9 is also provided with the paster that is crowned 10 being bonded on torpedo shell 3 inwalls, and described blasting fuse 8 bottoms form a firing tip 11 through square 6.While setting off, as long as firing tip 11 is lighted, in the process that blasting fuse 8 upwards burns, the powder grain 9 on its limit is ignited singly, produces a series of blast sound.This firecrackers are used safer.Wherein: in order to increase the placement amount of powder grain, preferably allow blasting fuse 8 be scroll and distribute, linearly shape is also fine certainly, and just the placement amount of powder grain is just fewer, but safe.
In the present embodiment, between described upper cover 5 and the top of torpedo shell 3, for being preferably, removably connect; Torpedo shell 3 can be changed after being finished like this, and box body 1 can be used every year, escapable cost;
In order further to improve security, as shown in Figure 3, described torpedo shell 3 is outer can also be surrounded by fire retardant 12; Fire retardant 12 plays fireproofing function on the one hand, can make on the other hand torpedo shell 3 structures firmer, and profile is more attractive in appearance.
As shown in Figure 4, the utility model also can be taked following scheme: the interior loudspeaker 13 that is preferably provided with of described box body 1; Loudspeaker 13 can expand blast sound, so more true to nature, because torpedo shell 3 can be changed after being finished, 13, box body 1 and loudspeaker need not all change at every turn, so, although in box body 1, added loudspeaker 13 to increase cost, but still there are good market prospects, loudspeaker 13 is prior art, directly from the buying assembling of electronic market, Huaian.
The protection domain of this patent is not limited to above-described embodiment.
