Description

Technical Field

[0001] The utility model belongs to the technical field of firecracker stands, in particular to an anti-fire-crossing firecracker stand. Background Art

[0002] Firecrackers can set off festive atmospheres, and the explosion of firecrackers is destructive. When setting off traditional firecrackers, they are placed directly on the ground and set off, which is likely to cause splashing and injuring people around. Therefore, using a firing stand can prevent firecrackers from blasting around. However, this kind of firing stand can only set off one firecracker at a time, and then fill it with subsequent firecrackers and ignite them again, which is troublesome to use. In the prior art, a firecracker stand with multiple barrels can be filled with multiple firecrackers at one time, but this kind of firecracker stand still needs to be ignited one by one, and while the firecrackers are being set off, a series of firecrackers may occur, igniting the surrounding firecrackers, and there is a certain delay after the firecrackers are ignited, and it is very likely that when people come forward to check, the firecrackers ignited by the series of firecrackers will explode, causing safety accidents. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a firecracker stand that prevents cross-fire and explosion during ignition, and uses wind curtain protection to avoid the danger of cross-fire and explosion during ignition, thereby ensuring the entertainment effect while ensuring safety.

[0004] The technical solution adopted by the utility model is as follows: the utility model provides an anti-stringing firecracker rack, including a supporting base frame, and an anti-stringing firecracker clamp arranged on the supporting base frame, the supporting base frame includes a support rod and a firing barrel, the support rod is used to support the firing barrel, the firing barrel is hollow, a support platform is provided on the outside of the firing barrel, the anti-stringing firecracker clamp is connected to the support platform through a bearing, the anti-stringing firecracker clamp includes a bottom plate, a placing tube and an anti-stringing fire wind curtain plate, the placing tube is hollow and has an opening at the top, the placing tube is arranged on the bottom plate, and the placing tubes are evenly arranged in a circle on the bottom plate, the anti-stringing fire wind curtain plate is arranged on the placing tube, and a side opening is provided on the firing barrel, which is used to allow the firecrackers in the placing tube to enter the firing barrel for ignition and be ejected from the firing barrel.

[0005] When a traditional firecracker stand is ignited and shot out, sparks will splash downwards and spread out in an arc. The higher the height of the firecracker, the larger the radiation range of the sparks. The sparks enter through the gap between the firecracker and the placement tube, and can easily ignite the remaining firecrackers, causing multiple firecrackers to explode in disorder. The impact force may cause the supporting frame to fall, and the firecrackers will then rush horizontally to the surroundings, causing harm.

[0006] Due to the installation of the anti-cross-fire wind curtain plate, the explosion airflow rushes towards the anti-cross-fire wind curtain plate to generate vortex, which then carries the sparks away in the reverse direction, preventing the sparks from entering the placement tube, thereby avoiding cross-fire.

[0007] Preferably, the anti-cross-fire air curtain plate is aligned with the top of the placement tube.

[0008] When the anti-cross-fire wind curtain plate is aligned with the top of the placement tube, the airflow generated by the explosion will produce a wind curtain and cover the entire surface of the anti-cross-fire wind curtain plate, thereby isolating the sparks. Compared with the anti-cross-fire wind curtain plate that is not aligned with the top of the placement tube, it can achieve the effect of completely eliminating cross-fire.

[0009] Furthermore, in order to allow the firecrackers to enter the firing barrel one by one, a clockwork spring connected to the bottom plate is provided on the support platform to control the placement tube to rotate and enter the firing barrel one by one.

[0010] Furthermore, in order to ignite the firecrackers one by one, the placement tube is provided with a fuse hole and an ignition hole, and the fuse of the firecracker is extended out of the fuse hole. When the firecracker is ignited, the flame passes through the ignition hole to ignite the fuse of another firecracker. Therefore, the fuse hole and ignition hole of two adjacent placement tubes are close to each other.

[0011] Furthermore, in order to control the rotation node of the anti-stringing firecracker clip after the spring is wound up, a low opening is provided on the firing barrel, the low opening is connected to the side opening, and the height of the low opening is smaller than the height of the side opening.

[0012] Furthermore, the height of the firecrackers is greater than the height of the placement tube, the height of the side opening is greater than the height of the firecrackers, and the height of the low opening is greater than the height of the placement tube.

[0013] First, wind up the mainspring, and then load firecrackers into the placing tube. After the firecrackers enter the side opening, they are blocked above the low opening. At this time, light the firecrackers. After the firecrackers fly out, the empty placing tube can be rotated out of the low opening, and the next firecracker is rotated into the placing tube and blocked above the low opening of the inner wall of the placing tube, thereby achieving the effect of igniting one by one.

[0014] Preferably, two support rods are provided, the bottom of the firing barrel supports the ground, and the support rods and the firing barrel form a tripod shape.

[0015] Preferably, an opening is provided at the bottom of the placement tube.

[0016] Preferably, the firing barrel is inclined.

[0017] The beneficial effects achieved by the utility model using the above structure are as follows: This solution provides an anti-crossfire firecracker stand, which is provided with a supporting base frame and an anti-crossfire firecracker clamp, which is used to set off firecrackers, which can improve safety, as well as entertainment and viewing effects. An anti-crossfire wind curtain plate is provided, and the airflow generated by the explosion is used to cover all the placement tubes through a negative pressure wind curtain, and the sparks are isolated, thereby eliminating the danger of crossfire, thereby preventing the firecrackers from being ignited out of order and causing the chamber to explode; and the driving force of the spring is used, and a specific opening is provided, so that the firecrackers can achieve the effect of rotating launch, and the fuse hole and the ignition hole are provided to achieve the effect of automatic ignition. The support form of the supporting base frame not only improves stability, but also has entertainment value. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1 As shown, the utility model provides an anti-stringing firecracker stand, comprising a supporting base frame 1, and an anti-stringing firecracker clip 2 arranged on the supporting base frame 1, the supporting base frame 1 comprises a supporting rod 3 and a firing barrel 4, the supporting rod 3 is used to support the firing barrel 4, the firing barrel 4 is hollow, and a supporting platform 5 is arranged on the outer side of the firing barrel 4, the anti-stringing firecracker clip 2 is connected to the supporting platform 5 through a bearing, as shown in FIG. Figure 2-3 The anti-cross-fire firecracker clamp 2 includes a bottom plate 6, a placement tube 7 and an anti-cross-fire wind curtain plate 8. The placement tube 7 is hollow and has an opening at the top. The placement tube 7 is arranged on the bottom plate 6, and the placement tubes 7 are evenly arranged in a circle on the bottom plate 6. The anti-cross-fire wind curtain plate 8 is arranged on the placement tube 7. A side opening 9 is provided on the firing barrel 4, which is used to allow the firecrackers in the placement tube 7 to enter the firing barrel 4 for ignition and be ejected from the firing barrel 4.

[0031] In order to allow the firecrackers to enter the firing barrel 4 one by one, a clockwork spring 10 connected to the bottom plate 6 is provided on the support platform 5 to control the placement tube 7 to rotate and enter the firing barrel 4 one by one.

[0032] In order to ignite the firecrackers one by one, a fuse hole 11 and an ignition hole 12 are provided on the placement tube 7. The fuse of the firecracker is extended out of the fuse hole 11. When the firecracker is ignited, the flame passes through the ignition hole 12 to ignite the fuse of another firecracker. Therefore, the fuse hole 11 and the ignition hole 12 of two adjacent placement tubes 7 are close to each other.

[0033] like Figure 4 In order to control the rotation node of the anti-stringing firecracker clip 2 after tightening the mainspring 10, a low opening 13 is provided on the firing barrel 4, and the low opening 13 is connected to the side opening 9, and the height of the low opening 13 is less than the height of the side opening 9.

[0034] The height of the firecrackers is greater than the height of the placement tube 7 , the height of the side opening 9 is greater than the height of the firecrackers, and the height of the low opening 13 is greater than the height of the placement tube 7 .

[0035] like Figure 5 First, wind up the mainspring 10, and then load firecrackers into the placement tube 7. After the firecrackers enter the side opening 9, they are blocked above the low opening 13. At this time, light the firecrackers. After the firecrackers fly out, the empty placement tube 7 can rotate out of the low opening 13, and the next firecracker rotates into the placement tube 7 and is blocked above the low opening 13 on the inner wall of the placement tube 7, thereby achieving the effect of igniting one by one.

[0036] There are two support rods 3, and the bottom of the firing barrel 4 supports the ground, and the support rods 3 and the firing barrel 4 form a tripod shape.

[0037] The bottom of the placing tube 7 is provided with an opening.

[0038] The firing barrel 4 is tilted.

[0039] Embodiment 1

[0040] The anti-cross-fire air curtain plate 8 is located lower than the top of the placement tube 7.

[0041] like Figure 6 When a traditional firecracker rack is ignited and fired, sparks will splash downward, and the sparks will spread in an arc shape. The higher the height of the firecracker, the larger the radiation range of the sparks. The sparks enter through the gap between the firecracker and the placement tube 7, which can easily ignite the remaining firecrackers, causing multiple firecrackers to explode in disorder. The impact force may cause the supporting frame 1 to fall, and then the firecrackers will rush horizontally to the surroundings, causing harm.

[0042] like Figure 7 In this embodiment, the anti-fire-crossing wind curtain plate 8 is provided, and the explosion airflow rushes toward the anti-fire-crossing wind curtain plate 8 to generate a vortex, which then carries the sparks away in the reverse direction, so that the sparks cannot enter the placement tube 7, thereby reducing the fire-crossing.

[0043] Embodiment 2

[0044] The position of the anti-cross-fire air curtain plate 8 is aligned with the top of the placement tube 7.

[0045] like Figure 8 In this embodiment, the airflow generated by the explosion will first contact the anti-fire-crossing wind curtain plate 8, and then spread out to form a wind curtain, and cover the entire surface of the anti-fire-crossing wind curtain plate 8, and then the subsequent falling sparks will be isolated by the wind curtain and carried away horizontally to the surroundings. Compared with the anti-fire-crossing wind curtain plate 8 in Example 1, this embodiment can achieve the effect of completely eliminating fire-crossing.

[0046] When in use, the support frame 1 is placed on a stable ground, the spring 10 is tightened, and then firecrackers are loaded into the placement tube 7, and the fuse is passed through the fuse hole 11. After the rotation force of the spring 10 drives the firecracker into the side opening 9, it is blocked above the low opening 13. At this time, the firecracker in the cannon barrel 4 is ignited, and the flame generated by the explosion passes through the ignition hole 12 to ignite the fuse of another firecracker, thereby achieving the effect of automatic continuous ignition. After the firecracker flies out, the empty placement tube 7 can rotate out of the low opening 13, and the next firecracker rotates into the placement tube 7 and blocks above the low opening 13 of the inner wall of the placement tube 7, thereby achieving the rotation effect of the anti-stringing firecracker clip 2 and achieving the effect of continuous ignition one by one.

[0047] During the process, the airflow generated by the explosion will produce an air curtain and cover the entire surface of the anti-crossfire air curtain plate 8, thereby isolating the sparks and completely preventing crossfire and explosion.
