Abstract
The utility model relates to an electric ignition tube for fireworks and firecrackers, which comprises a package cover and a lead; an outer cover is internally provided with powder; the electric ignition tube is characterized in that the outer cover of the electric ignition tube is also internally provided with a rapid fuse and an insulating base; the upper end of the outer cover is provided with a flaming hole and a flaming hole plug; the rapid fuse is contacted with the powder; the two ends of the rapid fuse are respectively connected with the upper ends of a metal contact pin A and a metal contact pin B by welding; the metal contact pin A and the metal contact pin B are fixedly connected with the insulating base; the lower ends of the metal contact pin A and the metal contact pin B are respectively connected with a press end of an ignition point; and the lower end of the outer cover is connected with the insulating base in a sealing way. The rapid fuse has a spiral structure; the electric ignition tube for fireworks and firecrackers is simple in structure, small in size, reliable in work and especially suitable for a controlled multiple ignition device of fireworks and firecrackers, and can produce the effect of continuous emission. The electric ignition tube is suitable for factory production.
Description
Technical field
The utility model relates to igniter, especially a kind of squib that is used for fireworks.
Background technology
The most volume of fireworks squib of the prior art is bigger, and it connects the manual hinge joint of employing during use, and speed of ignition is unstable, and poor reliability is only applicable to single fireworks and sets off; The squib cost that domestic everybody fireworks factory makes is high, also is not suitable for setting off of small-sized fireworks.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, volume is small, connection is quick, speed of ignition is stable, the squib that is used for fireworks of good reliability.
The purpose of the utility model realizes through following technical scheme: a kind of squib that is used for fireworks; Comprise ladle cover, lead-in wire, be provided with gunpowder in the outer cover, it is characterized in that: also be provided with rapid fuse, insulating base in the said squib outer cover; The outer cover upper end is provided with bocca and bocca plug; Said rapid fuse contacts with gunpowder, and its two ends are welded to connect with A, B metal haptic element upper end respectively, and A, B metal haptic element are fixedly connected with insulating base; Its lower end can be respectively and the ignition point press bond, and said outer cover lower end is connected with the insulating base envelope.Said rapid fuse is a helicoidal structure.
The beneficial effect of the utility model is: 1, volume is small, compact conformation, and its metal haptic element is connected closely with the squib socket, fast during use, and is easy to operate.2, the helical form rapid fuse closely contacts with gunpowder, and its fusing speed is fast, igniting is reliable, but the interior gunpowder of bocca plug protective cover avoids making moist at ordinary times, takes off during use conveniently.
The utility model is simple in structure, and volume is small, and reliable operation is specially adapted on the controlled multiple igniter of fireworks, produces the effect of emission continuously.The utility model is fit to plant produced.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-outer cover, 2-insulating base, 3-rapid fuse, 4,5-metal haptic element, 6-bocca, 7-bocca plug, 8-gunpowder.
The specific embodiment
Figure below combines accompanying drawing that the utility model is described further: among Fig. 1, a kind of squib that is used for fireworks comprises ladle cover, lead-in wire; Be provided with gunpowder in the outer cover; It is characterized in that: also be provided with rapid fuse 3, insulating base 2 in the said squib outer cover 1, outer cover 1 upper end is provided with bocca 6 and bocca plug 7, and said rapid fuse 3 contacts with gunpowder; Its two ends are welded to connect with A, B metal haptic element 4,5 upper ends respectively; A, B metal haptic element 4,5 are fixedly connected with insulating base 2, and its lower end can be respectively and the ignition point press bond, and said outer cover 1 lower end and insulating base 2 are tightly connected.Said rapid fuse 3 is a helicoidal structure.
The utility model need only insert its A, B metal pin in its corresponding priming supply socket when using, and pulled up the bocca plug, bocca was placed that the afterbody of fireworks gets final product in the transmitting tube again.At this moment, the preparation before the emission is accomplished, and after priming supply (9V) was connected, the igniting emission was promptly accomplished.
