A retractable net frame for fireworks with subtitle pattern

Abstract

The invention discloses a flexible net rack for subtitle-patterned fireworks. The flexible net rack comprises soft fireproof net distributed in a quadrangular frame, the frame consists of a telescopic rods, and locking devices are arranged among a plurality of telescopic sections forming the telescopic rods; each telescopic rod is axially provided with a sliding groove, one end of each of multiple frame net connecting pieces can axially move along the sliding groove so as to be arranged in the sliding groove, and the other end of each frame net connecting piece is connected with the circumference of the fireproof net. By utilizing the technical solution above, the assemble of the subtitle-patterned fireworks is carried out when the telescopic rods are extended, assembled effect pieces arefolded and clustered, each telescopic section of the telescopic rods in a transverse direction and a vertical direction is retracted into a maximum telescopic section, and then the package can be carried out. The volume of the packaged subtitle-patterned fireworks is largely reduced compared with the volume of the subtitle-patterned fireworks packaged by the prior art, and the package transportation cost is effectively reduced.

Description

technical field [0001] The invention relates to a subtitle pattern fireworks. Background technique [0002] Subtitle pattern fireworks have not only become an indispensable theme of fireworks displays in China, but also have been widely used in fireworks displays abroad. Although the existing subtitle pattern fireworks are mainly composed of metal grid substrates, although the grid frame can be curled for packaging, the volume of the existing subtitle pattern fireworks is still relatively large after assembly and molding, and the transportation costs for transporting them to foreign countries are quite high, resulting in excessive discharge costs. large, which limits the use of subtitle pattern fireworks in foreign countries; the industry also transports components to foreign countries for assembly and molding, but due to the lack of skilled industrial workers in foreign countries for this work, the assembly effect is difficult to meet actual needs. Sending domestic skilled...
