Description

Technical Field

[0001] This utility model relates to safety protection facilities for fireworks display, specifically a safety support for double-bang fireworks products. Background Technology

[0002] Setting off fireworks and firecrackers during festivals is one of the most important folk customs in my country. Since most fireworks shoot upwards, some cylindrical tubes are difficult to position during firing. If a tube tipps over, it can cause injuries, fires, or other safety hazards to nearby people or property. To avoid this hazard, supports should be provided for the tubes, such as the support disclosed in the Chinese utility model patent "Firecracker Firing Support (ZL201220271372.4)," which provides support for the tube and effectively prevents it from tipping over during firing. However, in actual use, this type of firing support has drawbacks. Because its fixing ring and frame are fixedly connected by the two ends of a connecting rod, although the connecting rod can extend and retract vertically, the overall size is large, and it is difficult to precisely control the extension and retraction length of each rod during the extension and retraction process. Therefore, the horizontality of the fixing frame is difficult to control, resulting in poor overall stability. Utility Model Content

[0003] This utility model addresses the technical deficiencies mentioned in the background art by providing a safe firing rack that is easy to assemble and disassemble, convenient to transport, and highly stable.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is: a safe ignition support, including a support leg, a large ring as a base, a small ring as a loading port, and a spring coil;

[0005] The support leg includes an upper vertical section and a lower inclined section; the upper part of the vertical section is provided with a second slot, the middle part with a first slot, and the lower part with a locking platform at the junction with the inclined section;

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] The safety firing bracket disclosed in this utility model is an improvement on the existing structure and is applied to the safety firing bracket of double-bang fireworks products. See appendix. Figure 2 This safety launcher includes support legs 6, a large circular ring 4 serving as a base, a small circular ring 2 serving as a loading port, and a spring coil 3. These four components are all independent plate-shaped, with multiple support legs 6. In this embodiment, there are three support legs 6.

[0026] The support leg 6 includes an upper vertical section 6-1 and a lower inclined section 6-2. The vertical section 6-1 has a second slot 7 at its upper part, a first slot 8 in its middle part, and a locking platform 10 at its lower part where it intersects with the inclined section 6-2. The outer side of the upper end of the vertical section 6-1 of the support leg 6 has an inclined surface structure, and the upper wall of the second slot 7 connects to the inclined surface structure. The bottom surface of the inclined section 6-2 of the lower support leg 6 is a flat surface.

[0027] In a preferred embodiment, a plurality of first assembly holes 5 are evenly distributed around the circumference of the large circular ring 4, and these first assembly holes 5 match the mounting platform 10. In this embodiment, the number of first assembly holes 5 is three, corresponding to the number of support legs. The first assembly holes 5 are elongated holes, and their length and width correspond to the width and thickness of the lower part of the vertical section 6-1.

[0028] In another preferred embodiment, a plurality of second assembly holes 1 are evenly distributed around the circumference of the small ring 2, and these second assembly holes 1 match the second slot 7. In this embodiment, the number of second assembly holes 7 is three, corresponding to the number of support legs. The second assembly holes 7 are elongated holes, and their length and width correspond to the width and thickness of the inclined portion at the upper end of the vertical section 6-1.

[0029] In another preferred embodiment, the spring coil 3 matches the first slot 8. The first slot 8 is located in the middle of the inner side of the vertical section 6-1 of the support leg 6, and its bottom is an arc shape that matches the spring coil 3. The spring coil 3 is an open ring, and its open end is provided with a handle for easy clamping and releasing.

[0030] The locking platform 10 is positioned at the junction of the vertical section 1 and the inclined section 6-2 of the support leg 6, located on both sides of the vertical section 6-1. An inwardly facing insertion port 9 is provided between the outer locking platform 10 and the side of the vertical section 6-1 of the support leg 6; this insertion port 9 serves as a limiting groove for the large ring. A second locking groove 7 is located on the outer side of the vertical section 6-1 of the support leg 6. This second locking groove 7 is recessed along the side wall of the vertical section 6-1 of the support leg, and its structure is similar to that of the insertion port 9; it serves as a limiting groove for the installation of the small ring. The vertical width of the insertion port 9 and the recessed groove corresponds to the thickness of the small ring 2 and the large ring 4.

[0031] Based on the above structure, the assembly process of this utility model is as follows:

[0032] 1. Pass the upper parts of the three support legs through the first assembly hole on the large ring in sequence, and then insert the outer wall of the first assembly hole of the large ring into the socket. (See attached diagram) Figure 3 ;

[0033] 2. After squeezing the spring ring tightly, insert it from above between the three support legs, and release it at the first slot position to allow the spring ring to engage in the first slot. Apply outward pressure to the three support legs to ensure a tight fit between the outer wall of the first assembly hole of the large ring and the insertion port. (See attached image) Figure 4 ;

[0034] 3. Align the second assembly hole on the small ring with the upper ends of the three support legs, insert them, and under the tension of the spring coil, the outer wall of the second assembly hole on the small ring will engage with the second slot. Ensure the large and small rings are level. (See attached diagram) Figure 1 .

[0035] During use, do not use in non-horizontal environments and ensure that moving parts are tightly connected. The inlet of the double-bang should face vertically upwards with the lead wire at the bottom, avoiding tilting. Standard-sized double-bangs should enter smoothly without jamming or resistance. Do not force in oversized items. After installation, remove any flammable materials from the surrounding area. After each use, check the inner wall for gunpowder residue and clean it promptly. Check that all parts are stable.
