A firecracker which can be ignited in sequence

Abstract

This utility model relates to the field of firecracker technology and discloses a firecracker that can be set off in sequence, comprising: a packaging shell and an isolation component disposed within the packaging shell; and firecrackers disposed within the packaging shell. The firecrackers consist of multiple layers of firecracker bodies, with adjacent firecracker bodies isolated in different cavities by the isolation component. Through the cooperation between the packaging shell, the isolation component, and the firecrackers, the packaging shell reduces the space occupied by the firecrackers during ignition, eliminating the need to unfold them. Simultaneously, the isolation component isolates the firecrackers rolled within the packaging shell, preventing subsequent firecrackers from igniting after the first firecracker is set off, ensuring that the firecracker bodies can be set off sequentially from top to bottom. Furthermore, the design of the packaging shell and the isolation component prevents concentrated ignition of the firecracker bodies, thereby improving the safety of setting off the firecrackers.

Description

Technical Field

[0001] This utility model relates to the field of firecracker technology, specifically to a type of firecracker that can be set off in sequence. Background Technology

[0002] Currently, firecrackers are made by connecting several firecracker pellets arranged in two rows into a string using a fuse, and then rolling them into a disc shape for easy sale, storage, and transportation. Because the gaps between the firecracker pellets in this traditional type of firecracker are large, they usually need to be unfolded into a long string of firecrackers to achieve the purpose of igniting them sequentially along the fuse.

[0003] However, traditional firecrackers need to be unfolded before they can be set off. Due to limitations of space and location, if they are not unfolded, the outer ring of firecrackers may ignite the other firecrackers in the inner ring when they explode, causing a fire to spread. In severe cases, this can even cause simultaneous explosions and injuries. Therefore, we need to propose a type of firecracker that can be set off in sequence. Utility Model Content

[0004] The purpose of this invention is to provide a firecracker that can be set off in sequence. By placing a series of firecrackers inside a tube and isolating adjacent firecrackers with an isolation component, the firecrackers are set off in a predetermined order. This reduces the impact of the firecrackers being set off on the firecrackers that are not yet set off, thereby ensuring that the firecrackers can be set off normally, reducing the space occupied by the firecrackers, and improving the safety of setting off the firecrackers, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a firecracker that can be set off in sequence, comprising:

[0006] Packaging shell, and insulating components disposed within the packaging shell;

[0007] Fireworks set inside the packaging shell;

[0008] The firecrackers consist of multiple layers of firecracker bodies, with adjacent firecracker bodies isolated in different cavities by an isolation component.

[0009] Preferably, the isolation component includes multiple sets of isolation rolls and multiple sets of isolation paperboards. The multiple sets of isolation rolls and multiple sets of isolation paperboards are alternately arranged in the inner cavity of the packaging shell. The isolation rolls are spirally wound between two adjacent sets of isolation paperboards, and the two sets of isolation paperboards are arranged in parallel.

[0010] Preferably, the path of the insulating paper roll forms a layout channel for placing the firecracker body, and the layout channel is arranged in a spiral shape and is housed together with the firecracker body.

[0011] Preferably, the outer packaging shell includes a protective paper shell, a supporting base plate, and a reinforcing cylinder. The reinforcing cylinder and the protective paper shell are both adhered to the upper surface of the supporting base plate, and the axis of the reinforcing cylinder and the axis of the protective paper shell are both arranged on the same straight line.

[0012] Preferably, each set of the isolation cardboard has a through hole in the middle for the reinforcing cylinder to pass through, one end of the isolation roll is glued to the outside of the reinforcing cylinder, and the other end of the isolation roll is glued to the inner wall of the protective cardboard shell.

[0013] Preferably, the outer packaging shell further includes a protective paper cover adhered to the upper opening of the protective paper shell, the thickness of the protective paper cover being the same as the thickness of the protective paper shell, the thickness of the supporting base plate being greater than the thickness of the protective paper cover, and the wall thickness of the reinforcing cylinder being greater than the thickness of the protective paper cover.

[0014] Preferably, the firecrackers also include a connecting wire that connects two adjacent firecracker bodies and an ignition wire that passes through the protective paper cover. The ignition wire is connected to the end of the uppermost firecracker body near the reinforced cylinder.

[0015] Preferably, the firecracker body is mainly composed of multiple sets of firecracker pellets and a fuse. The firing end of the multiple sets of firecracker pellets is provided with a firing fuse that is parallel to the fuse. Adjacent firecracker bodies are connected by connecting wires and fuses, and the ignition fuse is connected by winding to the uppermost fuse.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model mainly utilizes the cooperation between the packaging shell, the isolation component, and the firecrackers. The packaging shell reduces the space occupied by the firecrackers during ignition, eliminating the need to unfold them. Meanwhile, the isolation component isolates the firecrackers rolled up inside the packaging shell, preventing the firecrackers from igniting subsequent firecrackers after the main firecracker is lit. This ensures that the firecrackers are lit sequentially from top to bottom. Furthermore, the coordinated design of the packaging shell and the isolation component prevents the firecrackers from igniting simultaneously, thereby improving the safety of firecracker ignition.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a firecracker that can be set off in sequence, comprising:

[0026] Packaging shell 1, and isolation components disposed within packaging shell 1;

[0027] Fireworks 5 are set inside the outer packaging shell 1;

[0028] The firecracker 5 is composed of multiple firecracker bodies 51, and adjacent firecracker bodies 51 are isolated in different cavities by an isolation component.

[0029] The isolation assembly includes multiple sets of isolation paper rolls 2 and multiple sets of isolation paperboards 3. The multiple sets of isolation paper rolls 2 and multiple sets of isolation paperboards 3 are alternately arranged in the inner cavity of the outer packaging shell 1. The isolation paper rolls 2 are spirally wound between two adjacent sets of isolation paperboards 3, and the two sets of isolation paperboards 3 are arranged in parallel. When the ignition fuse 53 is lit, the flame first ignites the fuse 513 of the uppermost firecracker body 51, triggering the ignition of the firecracker pellets 511 in that layer. After that layer has finished igniting, the flame is transmitted through the connecting fuse 52 to the fuse 513 of the next layer of firecracker body 51, and so on, igniting each layer in sequence along the spiral channel.

[0030] The path of the isolation paper roll 2 forms a layout channel 4 for placing the firecracker body 51. The layout channel 4 is spirally arranged and is stored with the firecracker body 51. The layout channel 4 allows the firecracker body 51 to be spirally coiled, so that the firecracker body 51 does not need to be unfolded and lit, reducing the space for the firecracker body 51 to be lit, thereby improving the applicable environment for the firecracker to be lit.

[0031] The outer packaging shell 1 includes a protective paper shell 11, a supporting base plate 12, and a reinforcing cylinder 14. The reinforcing cylinder 14 and the protective paper shell 11 are both bonded to the upper surface of the supporting base plate 12. The axis of the reinforcing cylinder 14 and the axis of the protective paper shell 11 are both set on the same straight line. The protective paper shell 11 can protect the firecracker body 51 and improve the service life of the firecracker body 51. At the same time, the reinforcing cylinder 14 supports the coiled firecracker body 51 and improves the stability of the coiled firecracker body 51. Furthermore, the adjacent isolation cardboard 3 is supported by the isolation roll paper 2 to ensure the stability of the support for the firecracker body 51.

[0032] Each set of isolation cardboard 3 has a through hole in the middle for the reinforcing tube 14 to pass through. One end of the isolation roll 2 is glued to the outside of the reinforcing tube 14, and the other end of the isolation roll 2 is glued to the inner wall of the protective cardboard shell 11. The isolation roll 2 can isolate the firecracker body 51 while supporting the isolation cardboard 3, thereby improving the strength of the packaging shell 1 and facilitating the transportation of firecrackers.

[0033] The outer packaging 1 also includes a protective paper cover 13 glued to the upper opening of the protective paper shell 11. The thickness of the protective paper cover 13 is the same as the thickness of the protective paper shell 11. The thickness of the supporting base plate 12 is greater than the thickness of the protective paper cover 13. The wall thickness of the reinforcing cylinder 14 is greater than the thickness of the protective paper cover 13. The supporting base plate 12 is used to support the firecracker body 51. The protective paper cover 13 and the protective paper shell 11 can break when the firecracker pellets 511 explode, thus not affecting the explosion of the firecracker pellets 511.

[0034] The firecracker 5 also includes a connecting wire 52 that connects two adjacent firecracker bodies 51 and an ignition wire 53 that passes through the protective paper cover 13. The ignition wire 53 is connected to the end of the uppermost firecracker body 51 near the reinforcing cylinder 14. The ignition wire 53 is a green wire and contains barium nitrate, which burns at a slower speed, thus improving the safety when igniting the firecracker.

[0035] The firecracker body 51 is mainly composed of multiple sets of firecracker pellets 511 and a fuse 513. The firing end of the multiple sets of firecracker pellets 511 is provided with a firing fuse 512 that is parallel to the fuse 513. Adjacent firecracker bodies 51 are connected to the fuse 513 by connecting wires 52. The ignition wire 53 is connected to the uppermost fuse 513 by winding. The multiple sets of firecracker pellets 511 are arranged in two rows and connected to the fuse 513 by the firing fuse 512, so that the fuse 513 can ignite the firing fuse 512 on the firecracker pellets 511, realizing the sequential ignition of the firecracker body 51. At the same time, the firing fuse 512, the fuse 513 and the connecting wire 52 are all white wires containing potassium chlorate, which burns quickly and usually explodes instantly after being ignited.

[0036] In use, the ignition fuse 53 exposed on the outside of the packaging shell 1 is lit, which ignites the top layer of firecracker body 51. The firecrackers are set off starting from the center of the winding of the firecracker body 51 and then sequentially outward along the layout channel 4. The outermost layer of the next layer of firecracker body 51 is ignited by the connecting fuse 52, and then the firecrackers are set off inward along the layout channel 4. The isolation components, through the design of the isolation roll 2 and the isolation cardboard 3, can prevent the ignited firecracker body 51 from affecting the unignited firecracker body 51, prevent adjacent layers of firecracker body 51 from igniting prematurely, and ensure that the firecrackers are set off in a spiral path layer by layer, ultimately achieving orderly and continuous firecrackers set off in multiple layers.
