Paper tube combined firework setting-off emission device

Abstract

The invention discloses a paper tube combined firework setting-off emission device. The paper tube combined firework setting-off emission device is characterized in that the device comprises a combined tube body supporting seat, N emitting tube body units, connection positioning rods and a combined tube body top cover; N tube body supporting convex columns are arranged on the combined tube body supporting seat; N downward-protrusive top cover fixing tube sleeves which correspond to the N tube body supporting convex columns on the tube body supporting seat are arranged on the bottom surface below the combined tube body top cover; and top cover fixing devices and supporting seat fixing devices which are used for insertion and fixed connection of the connection positioning rods are respectively and correspondingly arranged at four corners and the centers of the combined tube body top cover and the tube body supporting seat; and the components are matched to form a combined firework setting-off emission device combined structure with an integral structure. The paper tube combined firework setting-off emission device has the advantages of being simple in structure, combining and installing various firework tubes conveniently, rapidly and firmly, and being safe and reliable in setting-off emission.

Description

technical field [0001] The invention belongs to the technical field of combined firework discharge devices, in particular to a recyclable and recyclable paper tube combined fireworks discharge device mainly used for supporting and fixing combined fireworks of paper tube structure. Background technique [0002] Fireworks is a traditional product with a long history. It is an indispensable joyful product whether it is a festival or a festival performance. One of the main festive fireworks products for viewing joy. [0003] At present, it is generally a single base-type discharge device for combining fireworks discharge and launching devices, and the ignition lead and string fire lead are all arranged at the bottom of the base to open lead grooves. The main defect of this base-type discharge and launch device is that the base The lead wire in the lead groove at the bottom of the bottom is easy to be affected by moisture because it is close to the ground, which will affect the ...

Problems solved by technology

[0003] At present, it is generally a single base-type discharge device for combining fireworks discharge and launching devices, and the ignition lead and string fire lead are all arranged at the bottom of the base to open lead grooves. The main defect of this base-type discharge and launch device is that the base The lead wire in the lead groove at the bottom of the bottom is easy to be affected by moisture because it is close to the ground, which will affect the ignition and discharge; at present, there is also a kind of all-plastic composite firework launcher. The disadvantage of this all-plastic composite firework launcher is that due to the overall structure Plastic injection molding is used, which has a great impact on environmental protection, and the launch tube will produce toxic gas when the drug is burned at high temperature, which will be released in the air. Also, the lead wire is installed at the bottom of the composite emitter, which is easily affected by the moisture on the ground and the lead wire will be affected by moisture. When causing fireworks to be set off, the string fire fuse cannot catch fire, therefore, causing set off failure

This discharge device structure is inconvenient to assemble and has poor practicability

Another example is in the patent literature of the State Intellectual Property Office, the notification number is CN206683501U, which discloses "A Fixture for Setting off Fireworks". , four positioning frames are arranged vertically upwards around the circular disc body, a plurality of sand filter holes are evenly arranged at the bottom of the inner cavity of the circular disc body, and a sand tray is arranged below the circular disc body, and a sand table is arranged on the four sides A circular top cover is installed on a positioning frame. The appearance of this invention patent seems simple, but its internal structure is complex and there are many parts. The fireworks are surrounded by a rectangular iron block surrounded by a ring, and the supporting components are used to enclose the fireworks. Enclosing the fireworks in one space is safe, but it is not practical, and it is not suitable for the combined discharge of a variety of fireworks products of different sizes.

[0005] In short, from the analysis of the current existing technology, the molded combined fireworks launching cylinder and the fully plastic combined fireworks launching cylinder cannot be used to assemble export products because they do not meet environmental protection requirements. In order to improve the upgrading of combined fireworks and accelerate the launch of fireworks Advances in device technology, innovative research and development of a new type of combined firework launch device that can be used to support and fix the combined structure of the paper tube
