Embodiment Construction

[0023] Such as figure 1 As shown, the non-expanding firecrackers include firecrackers 2 connected in series through a fuse 3 and rolled into a disk-shaped firecracker disc 1 . What the present invention differs from the traditional disc-shaped firecracker string is that a flame-retardant interlayer 5 is arranged on the outside of the firecracker string, such as figure 2 As shown, the width of the flame-retardant interlayer 5 is greater than the distance between the firecracker pellets 2 cylinders on both sides of the firecracker string fuse 3 and covers the fuse 3 and the firecracker lead 4 of the firecracker string, so that the fuse 3 and the firecracker lead 4 are separated from the outside world . Due to the adoption of this structure, when the firecrackers in the present invention were not launched, the firecracker disc 1 was positioned at the firecracker string of the outer layer when the firecracker strings were set off. Ignite the fuse of the firecracker disc located...

Abstract

The invention relates to an unfolding-free explodable firecracker, aiming to solve the defect of the existing explodable firecracker which needs to be unfold in the shape of a disc. The invention provides the unfolding-free explodable firecracker, wherein the firecracker comprises a firecracker string containing firecracker pellets connected in series through a lead, the firecracker string is swirled into a firecracker disc which has a plurality of layers inside and outside and is in the shape of a disc, and the outside of the firecracker string is provided with an antiflaming interlayer which is used for covering an interspace between the firecracker pellets at two sides of the lead. When the firecracker provided by the invention is set off, the firecracker string arranged outside the firecracker disc can produce spark and heat during lead burning and firecracker pellet explosion, the internal lead of the firecracker can not be ignited due to the resistance from an antiflaming interlayer, therefore, the purpose of setting off the firecracker in an unfolding-free mode is realized.

Description

technical field [0001] The present invention relates to firecrackers, more specifically, relates to a firecracker that can be set off without unfolding. Background technique [0002] Existing firecrackers are all made of a number of firecracker grains connected in series through a fuse to form a firecracker string, and then rolled into a disc for storage, transportation and sales. In order to prevent moisture, a layer of moisture-proof paper is usually wrapped around the firecracker string and then rolled into a Disc. This kind of firecracker needs to be unfolded when it is set off. If it is not unfolded, the firecracker may not be set off along the fuse. The heat or sparks generated by the explosion of the outer layer of firecrackers and the burning of the fuse may directly cause the fuse of the inner layer of firecrackers. The case of skewers. However, launching and setting off brings many disadvantages, such as the need for a large enough site to ensure that each sectio...
