Description

Technical Field

[0001] The utility model relates to a firecracker. Background Art

[0002] In the prior art, long firecrackers are spirally rolled into a disc (called a "coil firecracker") and packaged for sale. To set off a firecracker, the package must be opened to remove the coil firecracker, which is then unrolled back into its long, strip-shaped form and laid out on the ground or suspended for setting off. This disadvantage is its inconvenience. Furthermore, the lack of variation in the firing methods of firecrackers over the years has failed to meet consumers' demand for novelty and innovation. Utility Model Content

[0003] To address the above-mentioned drawbacks, the technical problem to be solved by the present invention is to provide a convenient-to-use coil firecracker with variable firing modes to enhance the fun. To address the above-mentioned technical problems, the present invention adopts a technical solution comprising a pull-to-rotate unwinding firecracker, comprising a coil firecracker placed in a packaging box, characterized in that a rotating mechanism is provided in the center of the packaging box, an opening is provided on the side of the packaging box, and a long strip of firecracker is spirally rolled into a coil firecracker around the rotating mechanism, with the ignition end of the firecracker being arranged corresponding to the opening.

[0004] The beneficial effect of the present invention is that when setting off the firecrackers, there is no need to open the packaging box to take out the firecrackers. The firecrackers can be set off by directly pulling the ignition end of the firecrackers out of the opening, which improves the convenience. At the same time, the rotating extraction method brings about a change in the setting off method, which satisfies the consumer psychology of seeking novelty and change, and improves the fun of setting off the firecrackers.

[0005] In one embodiment, the rotating mechanism includes a central disk, and the long strip firecrackers are spirally rolled up around the central disk to form a disk firecracker.

[0006] In one embodiment, the center disk is provided with a shaft sleeve for mounting a rotating shaft, and the rotating shaft is provided with a seat body located outside the packaging box, which is convenient for installation.

[0007] In one embodiment, the center disk is provided with a fixing member for the inner end of the firecracker. Preferably, the fixing members are evenly distributed around the circumference of the center disk. Preferably, the fixing member is a bayonet provided on the center disk. This facilitates production.

[0008] In one embodiment, the rotating shaft is composed of an upper rotating shaft and a lower rotating shaft that are sleeved together, and the outer ends of the upper rotating shaft and / or the lower rotating shaft are provided with a seat located outside the packaging box, which is convenient for assembly.

[0020] See attached Figure 1-4 The pull-rotate unwinding firecracker includes a packaging box 1, the center of which is provided with a rotating mechanism. In this example, the rotating mechanism includes a central disk 2, around which the long strip firecracker 3 is spirally rolled into a coil.

[0021] In the example, the center disk 2 is provided with a shaft sleeve 4 in the center for mounting the rotating shaft. The rotating shaft is composed of an upper rotating shaft 5 and a lower rotating shaft 6 that are connected together. The outer ends of the upper rotating shaft 5 and the lower rotating shaft 6 are respectively provided with a seat body 7 located outside the packaging box 1.

[0022] In the example, the center plate 2 is provided with a fixing member for the inner end portion 301 of the firecracker 3. The fixing member is a bayonet 8 provided on the center plate 2. In the example, three bayonet 8 are evenly distributed on the circumference of the center plate.

[0023] During production, any bayonet 8 can be selected, the inner end 301 of the firecracker 3 is inserted into the bayonet 8, and the elongated firecracker 3 is spirally rolled around the central disk 2 to form a coil firecracker; the coil firecracker is then placed in the packaging box 1 and sealed. The side of the packaging box 1 is provided with an opening 9, and the ignition end 302 of the firecracker 3 is arranged corresponding to the opening 9; the packaging box 1 is provided with a central hole 10 on both the upper and lower sides, and the upper rotating shaft 5 and the lower rotating shaft 6 are respectively inserted into the shaft sleeve 4 of the central disk 2 through the upper and lower central holes 10 to form a rotating shaft. The two base bodies 7 are both located outside the packaging box 1. Installation and assembly are convenient.

[0024] When setting off the firecrackers, there is no need to open the packaging box 1 to take out the firecrackers. The firecrackers 3 can be directly pulled out of the opening 9 by pulling the ignition end 302, thereby increasing the convenience. At the same time, the rotating extraction method brings about a change in the method of setting off the firecrackers, which satisfies the consumer psychology of seeking novelty and change. A certain length of firecracker strips can also be extracted as needed, and the rest of the firecrackers can be bundled and set off in the packaging box, thereby increasing the fun of setting off the firecrackers.
