Description
Technical Field
The utility model relates to the technical field of firecracker setting-off equipment, in particular to a double-sound firecracker safety setting-off device.
Background
This section introduces the reader with background information that may be relevant to various aspects of the embodiments of the utility model, and is believed to provide the reader with useful background information to aid the reader in a better understanding of the various aspects of the embodiments of the utility model. It is to be understood, therefore, that the description in this section is for the purpose of illustration and not an admission that the prior art is prior art.
The two skirts need to depend on the recoil generated by gunpowder when the gunpowder at the bottom explodes to lift off, and the two skirts have certain danger when being set off. Two layers of gunpowder are arranged in a paper cylinder of the double-bang firecracker, propelling gunpowder is arranged at the inner lower part of the round cylinder, explosion gunpowder is arranged at the inner upper part of the round cylinder, the propelling gunpowder is communicated with a fire-guiding cable, the propelling gunpowder is firstly ignited by the fire-guiding cable, and the propelling gunpowder detonates downwards to generate propelling force to lift the round cylinder into the air, and then the explosion gunpowder explodes, and the firecracker is in air.
The double-bang firecracker is a single firecracker, the double-bang firecracker must be ignited one by one, the double-bang firecracker is placed on the ground under the influence of ground conditions, the double-bang firecracker is not placed evenly, if the double-bang firecracker is placed unevenly or under the action of wind power, the double-bang firecracker can be inclined and inverted when being ignited and launched, and the double-bang firecracker is shot to pedestrians or other objects after being lifted off, so that personal injury or fire disaster is caused, and the potential safety hazard is greatly caused, and meanwhile, the setting-off effect is greatly influenced. Before the double-bang firecracker is ignited, the firecracker body must be erected on the ground, and a flat position is required to be selected for setting off. In this process, finding a suitable place for ignition wastes a lot of time. The traditional double-bang firecracker setting off mode is to set off one by one, every setting off one two skirts needs to be close to the setting off person to be ignited once, and the danger of explosion injury or burn is inevitably generated during multiple times of ignition. In order to avoid the problem, some safe setting-off devices capable of fixing double-bang firecrackers appear, but the firecracker setting-off devices are inconvenient to use, not only can the positions of the firecrackers not be fixed, but also the recoil generated during the combustion of the firecrackers can not be effectively reduced, so that the setting-off devices are sometimes used to cause larger damage.

The following describes the deployment of the double-bang firecracker safety setting-off device provided by the embodiment of the utility model in detail.
As shown in fig. 6 to 16, in the embodiment of the present utility model, when the double-bang firecracker is set off, the bottom cover 2 is opened first to expose the bottom opening 13, and the double-bang firecracker is thrown from the bottom opening 13 with the bottom downward. The fuse part 31 of the double-sound firecracker 3 passes through the notch 10 and is kept. Closing the bottom cover 2, wherein the bottom cover 2 covers the bottom opening 13 of the firecracker setting-off cylinder body 11; the blocking edge 20 shields a part of the notch 10. Igniting the fuse part 31 of the double-bang firecracker 3, the double-bang firecracker 8 pushes powder to detonate downwards, the tail flame after the double-bang firecracker 3 is set off passes through the opening, the generated pushing force pushes the blocking edge 20, the bottom cover 2 is further enabled to rotate and separate from the opening 13 at the bottom of the firecracker setting-off cylinder body 11, after the double-bang firecracker 8 is emitted out of the firecracker setting-off cylinder body 11, the bottom cover 2 is thoroughly opened to restore to an initial state, and thus one-time emission is completed.

As shown in fig. 1 to 17, in order to effectively ensure that the dual-bang firecracker 8 pushes the gunpowder to detonate downwards, the tail flame after the dual-bang firecracker 3 is set off passes through the opening 10, the size of the opening 10 is enough to enable the tail flame after the dual-bang firecracker is set off to pass through the opening 10 to push the blocking edge, and the height of the blocking edge 20 is lower than that of the opening 10. Further rotating the bottom cover 2 away from the opening 13 in the bottom of the firecracker setting-off barrel body 11. Optionally, the cross section of the blocking edge is in a circular arc shape matched with the outer wall of the firecracker setting-off cylinder body 11. The blocking edge 20 is also provided with a handle 27 for manually opening or closing the bottom opening 13 of the firecracker setting-off cylinder body 11 by the bottom cover 2.
In order to maintain the setting-off stability of the double-bang firecracker 2, the firecracker setting-off device is shown in fig. 18, and is capable of stably supporting any angle to be emitted at any time, and further comprises a bracket 5, wherein a sliding rail 51 is arranged on the bracket, a sliding block 15 is arranged on a firecracker setting-off cylinder, and the sliding block 15 reciprocates in the sliding rail 51. The double-bang firecracker 3 pushes the gunpowder to detonate downwards, the pushing force generated by the downward deflagration pushes the firecracker setting-off cylinder 1 to move in the opposite direction, and the firecracker setting-off cylinder 1 moves backwards, so that the firecracker is effectively simulated to be launched. A resetting device is further arranged in the sliding rail 51, and the resetting device effectively ensures that the firecracker setting-off cylinder 1 is reset after moving in the opposite direction. In order to facilitate the adjustment of the angle of the firecracker setting-off cylinder 1, the bracket is provided with a hinge shaft 52, and the hinge shaft 52 is hinged with the sliding rail 51. Further, the bracket 5 is further provided with an angle adjusting device 53 for adjusting the firecracker setting-off cylinder 1 so as to adjust the firing angle according to actual conditions.
