Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 Shown in -3, a kind of fireworks substrate has stringing base 6 and cylinder 15, and cylinder 15 is inserted in the stringing base 6. There is a circular pit 4 on the top 9 of the serial lead base 6, the inner peripheral surface of the circular pit 4 is an inner cylindrical surface 8, and the junction of the inner cylindrical surface 8 and the bottom surface 12 of the circular pit 4 is a rotating arc surface 11 , There is a boss in the center of the circular pit 4, the boss top is a round platform 1, there is a hole 2 communicating with the following 10 of the string lead base 6 on the top of the boss 1, and a small groove 3 is also arranged on the boss top. The lower part of the boss is a cylinder 5. A groove 7 is arranged below the serial lead base 6, and the groove 7 communicates with the holes 2 of all bosses. Th...

The invention discloses a fireworks basal body. The fireworks basal body is provided with a serial leading base and a tube cake; and the tube cake is inserted in the serial leading base. The serial leading base is a plate; a circular pit is in the upper surface of the plate; the inner peripheral surface of the circular pit is an inner cylindrical surface; a boss is in the center of the circular pit; a hole for communicating with the lower surface of the plate is formed in the upper surface of the boss; a channel is formed in the lower surface of the plate; the channel in the lower surface of the plate communicates with the hole of the boss; the tube cake is formed by single tube; single tube is provided with a tube body and a tube bottom; a through hole is formed in the center of the tube bottom; and one tube is inserted in one circular pit of the serial leading base. Compared with the prior art, the fireworks basal body has the advantages of: simple structure, high reliability, simplification of procedures, reduction of the cost, and improvement of the product number and quality.
Description
technical field [0001] The invention relates to a fireworks device, in particular to a fireworks base body. Background technique [0002] In the production of fireworks, one end of the paper tube must be closed. The traditional process is commonly known as "mud head", that is, the soil is compacted at one end of the paper tube to form a mud layer for sealing and isolation. This method requires a large amount of soil, which damages the environment, and the soil pollutes the environment after the fireworks are set off. Manual "cracking" is labor-intensive, the working environment is poor, and the production efficiency is low. However, the mechanical "mud pressing head" has a large footprint, complex structure and poor reliability. Recently, the mud head is replaced by a round paper sheet, that is, the round paper sheet is first punched out, and then pressed into the paper tube. In this method, manual operation is time-consuming and laborious, and the cost of machinery is ve...
