Abstract

The utility model discloses a delay fuse device of combined fireworks or large festive fireworks, which comprises a tube and a delay fuse, wherein the delay fuse is laid in the tube, and is fixed in the tube through a solid primer agent. Preferably, the tube adopts a firecracker tube. If the delay time is required to be shortened, black powder is filled at the tail end of the delay fuse in the tube. The delay fuse device has the benefits that firstly, the delay fuse is fixed in the tube through the solid primer agent, so that the delay time of setting off can be effectively controlled; secondly, the thickness of muddy bottom is controlled in the combined fireworks, the length and the weight of an inner tube are reduced, the amount of the black powder can be reduced, and the amount of paper material of an outer tube is also reduced, so that the cost of the whole combined fireworks is reduced; and thirdly, the large festive fireworks are manufactured through new processes that firstly the delay fuse device is installed on a spherical shell, then effective powder is put into the spherical shell, ball pasting and drying are performed, and finally the fuse is installed and the black powder is packed, therefore, the processes are greatly simplified, and the large festive fireworks are safe to manufacture.

Description

The time-delay fuse device of a kind of combined firework or display shell

Technical field

The utility model relates to fireworks and display shell, the time-delay fuse device of promptly a kind of combined firework or display shell.

Background technology

Time-delay fuse device is all arranged in combined firework and display shell, in combined firework, the time-delay fuse is fixed on the center at the bottom of the inner core mud, time-delay fuse bottom is a black powder, top is the effect medicine, when certain effects needs the long period, the time-delay fuse also just prolongs on year-on-year basis, just more thick and heavy at the bottom of the mud of constant time lag fuse like this, this has just increased the length and the weight of inner core, will consume propellant powder at the bottom of the interior thick and heavy mud of inner core more, inner core is long more, it is unstable more to go up to the air, and has also strengthened the holding capacity of urceolus simultaneously, thereby has increased whole cost.In the making of display shell, traditional manufacturing technique is as follows: 1, the brown paper skirt is installed on fire works display projectile shell; 2, dress effect medicine is stuck with paste good shot, dries; 3, get through skirt with bamboo let; 4, in skirt, place the time-delay fuse, allow the lower end of time-delay fuse contact with the effect medicine; 5, with glue fuse cord is installed in skirt upper end, is allowed the lower end of fuse cord and the last end in contact of time-delay fuse; 6, cut the fuse cord upper end, the insurance lead-in wire of starting to exchange fire is installed; 7, ignition fuse is installed, is wrapped black powder.Above-mentioned whole procedure more complicated, loaded down with trivial details, and after installing medicine, it is very dangerous to get through skirt with bamboo let.

Summary of the invention

For the mud base thickness weight and the time-delay fuse device production process complexity of display shell, unsafe shortcoming in the time-delay fuse device that overcomes combined firework, the utility model proposes the new design of the time-delay fuse device of a kind of combined firework or display shell.

The time-delay fuse device of this combined firework or display shell comprises little tube and time-delay fuse, and the time-delay fuse is placed in the little tube, it is characterized in that, the time-delay fuse is fixed in the little tube by solid flashing composition.

Little tube is preferably firecracker cylinder.

Shorten delay time if desired, the terminal black powder of filling of the time-delay fuse in little tube.

Advantage of the present utility model: 1, the time-delay fuse is fixed in the little tube by solid flashing composition, and time-delay fuse one end contacts with black powder, and the other end contacts with the effect medicine, can effectively control the time of setting off time-delay; 2, in combined firework, controlled the thickness at the bottom of the mud, also can guarantee the needs of combined firework time-delay; Reduce the length and the weight of inner core, can reduce the consumption of black powder, and reduced the consumption of urceolus paper material, thereby reduced the cost of whole combined firework; 3, in display shell, new production process is, time-delay thread guide devices of the present utility model is installed on spherical shell earlier, adorns the effect medicine then, sticks with paste ball, dries, and fuse is installed at last, and the bag black powder has been simplified operation greatly, and makes and make the safety that becomes.

Description of drawings

Fig. 1 uses schematic diagram of the present utility model in the combined firework;

Fig. 2 uses schematic diagram of the present utility model in the display shell;

Among the figure: 1, urceolus; 2, at the bottom of the mud; 3, black powder; 4, fuse; 5, the scraps of paper; 6, inner core; 7, following solid flashing composition layer; 8, firecracker cylinder; 9, solid flashing composition; 10, time-delay fuse; 11, effect medicine; 12, go up the solid flashing composition layer; 13, spherical shell; 14, open quick-fried medicine; 15, pearl brightening drug; 16, main lead-in wire.

The specific embodiment
