Description

Technical Field

[0001] This utility model relates to the field of fireproof cover technology, and in particular to a foldable fireproof cover for firecrackers. Background Technology

[0002] Firecrackers, also known as bangzhu, firecrackers, or firecrackers, are products that explode when lit, producing loud noises, flashes, and other effects, primarily for auditory impact. Later, due to their strong festive connotations, they evolved into a symbolic representation of bidding farewell to the old year and welcoming the new, becoming a folk custom most representative of the arrival of the New Year.

[0003] When setting off firecrackers, any flammable materials nearby must be cleared away, otherwise it can easily cause a fire. We know that when firecrackers explode, the paper scatters over a large area. Clearing away flammable materials over a large area is time-consuming and laborious, and you may miss the time to set off the firecrackers. The usual solution is to place a large metal box in the area where the firecrackers are set off, and then set off the firecrackers inside the metal box. However, large metal boxes are very heavy and very troublesome to move, especially on rugged paths, making them inconvenient to move and use.

[0004] Therefore, those skilled in the art have provided a foldable fireproof cover for firecrackers to solve the problems mentioned in the background art. Utility Model Content

The head of the positioning pin 8 is threaded with a nut. The diagonal dimension of the nut is larger than the inner diameter of the rope hole, which can prevent the rope hole from detaching from the positioning pin. This makes the connection between the protective cloth 14 and the pull rod 6 and the reinforcing base rod 21 more stable. After unscrewing the nut, the rope hole can detach from the positioning pin 8. At this time, the protective cloth 14 can be quickly removed for easy disassembly and convenient storage and carrying.

[0032] The protective cloth 14 has multiple elliptical windows that gradually decrease in size from bottom to top on its side. A breathable mesh 15 is installed at each elliptical window to facilitate the discharge of high-pressure gas generated by the firecracker explosion and reduce the impact of the gas on the protective cloth.
