Description

Technical Field

[0001] The invention relates to the field of fireworks setting off equipment, in particular to an environmentally friendly plastic mold fireworks structure. Background Art

[0002] Traditional firework launchers are formed by gluing paper tubes together, and the launch barrel is formed by gluing paper tubes together. The product can only be obtained through multiple processes such as paper cutting, rolling, drying, cutting, pressing soil to seal the bottom, gluing, drilling and threading. The process is relatively complicated and the production efficiency is relatively low. In addition, the paper tube is easily affected by moisture, and the gunpowder in the paper tube is prone to moisture failure. When the gunpowder is damp and heated to a certain temperature, it is easy to explode naturally, which poses certain safety hazards. The base of the launcher is made of hard shell kraft paper, which often burns to ashes along with the gunpowder after the firing is completed. In terms of safe firing, improving production efficiency and environmental protection, it is particularly important to improve production efficiency, ensure safe firing and increase material recovery rate.

[0003] In recent years, a one-off molded plastic fireworks has become popular in the industry. The launch device is divided into a launch tube and a base, which are integrally injection molded by a mold machine. The shape and structure of the molded body are similar to those of traditional combination fireworks. The overall appearance of the main body of the molded body is generally a rounded prism or cylinder. The launch tube is a number of parallel and evenly distributed tubular cavities. The structure and function of the tubular cavity are similar to the single tube of traditional combination fireworks. The upper and lower ends of the tubular cavity are open, and the lower end is connected to the launch base. The launch base is provided with a wiring groove. The tubular cavity is built-in to launch pyrotechnics and effects. The launch tube and the base are connected by pressure fitting, snap connection, etc. However, the one-off molded plastic fireworks still have some disadvantages, especially the easy occurrence of string fire phenomenon. The string fire phenomenon will cause the gunpowder and effect parts in each tubular cavity to not be ignited and fired in sequence by the fuse according to the designed firing procedure, but two or more tubular cavities will be fired almost simultaneously, completely destroying the firing effect. Summary of the invention

[0004] The purpose of the present invention is to provide an environmentally friendly plastic mold firework structure to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: An environmentally friendly plastic molded fireworks structure comprises a plurality of vertically evenly distributed launch tubes, each launch tube having an opening at the top end and sharing a top surface, each launch tube having a closed bottom end, and each launch tube having a fire transmission hole extending through the closed end; each launch tube having a base uniformly and detachably engaged at the bottom end, a through hole extending through the position where the base engages with the bottom end of each launch tube; and a fence-shaped protrusion is provided on the top of the base.

[0006] In a further embodiment, the fence-shaped protrusion is arranged around the bottom end of each launch tube, and the fence-shaped protrusion is semi-circular or linear.

[0007] In a further embodiment, it further includes a lead wire arrangement mechanism.

[0008] In a further embodiment, the lead wire arrangement mechanism includes a lead wire groove opened at the bottom of the base. The lead wire grooves are distributed between adjacent through holes. A lead wire limiting protrusion is fixed at the bottom end of the launch tube. The lead wire limiting protrusion extends downward through the through hole and jointly forms a serpentine lead wire arrangement mechanism with each lead wire groove.

[0009] In a further embodiment, the middle part of the lead wire groove bulges to form a truncated groove.

[0010] In a further embodiment, the side wall of the base protrudes downward from the bottom surface of the base, and a plurality of pressure relief grooves and lead wire openings are opened on the side wall of the base.

[0011] In a further embodiment, the top side wall extends downward to form a protective cylinder body. The protective cylinder body covers each launch tube together with the base, and a pressure relief groove matching the base is opened at the bottom of the protective cylinder body.

[0012] In a further embodiment, the side wall of the base extends upward to form a protective cylinder body. The protective cylinder body wraps each launch tube together with the top surface therein.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by providing a fence-shaped protrusion on the top of the base, the present invention realizes the effect of spacing the bottom ends of each launch tube from each other, which can effectively avoid the phenomenon of cross-fire between the launch tubes, so that the gunpowder and effect components in each launch tube can be sequentially ignited and launched by the fuse according to the designed firing procedure, and the situation where two or more launch tubes are almost launched simultaneously will not occur, ensuring the firing effect.

[0014] Second, the base and the launch tube of the present invention are detachably snap-connected, which can facilitate the inspection and maintenance of the installation quality between the launch tube and the base. In addition, this detachable and installable structure also facilitates the arrangement and inspection of the lead wire between the launch tube and the base, thus ensuring the firing effect of the fireworks and effectively reducing the explosion risk of the fireworks.

[0015] Third, the lead wire groove on the base of the present invention and the lead wire limiting protrusion at the bottom end of the launch tube can jointly play a role in combing the firing lead wire, facilitating the programming and design of the firing procedure. Moreover, the above structure greatly reduces the possibility of cross-fire between the lead wires, so that the gunpowder and effect components in each launch tube can be sequentially ignited and launched by the fuse according to the designed firing procedure, ensuring the firing effect.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0019] As Figures 1-4As shown in the figure, this embodiment provides an environmentally friendly plastic mold fireworks structure, which includes a number of vertically and evenly distributed launching tubes 1. The top openings of each launching tube 1 share the top surface 2, and the bottom ends of each launching tube 1 are closed. A fire transfer hole 3 is penetrated and opened at the closed end of each launching tube 1; a base 4 is detachably clamped at the bottom end of each launching tube 1, and a through hole 5 is penetrated and opened at the position where the base 4 is clamped with the bottom end of each launching tube 1; a fence-shaped protrusion 6 is provided on the top of the base 4, and the fence-shaped protrusion 6 is arranged around the bottom end of each launching tube 1, and the fence-shaped protrusion 6 is semicircular or linear. The side wall of the base 4 protrudes downward from the bottom surface of the base 4, and a number of pressure relief grooves 9 and lead wire ports 12 are opened on the side wall of the base 4. In this embodiment, by providing a fence-shaped protrusion 6 on the top of the base 4, the effect of spacing the bottom ends of each launching tube 1 from each other is achieved, which can effectively avoid the phenomenon of fire spreading between the launching tubes 1, so that the gunpowder and effect components in each launching tube 1 can be sequentially ignited and launched by the fuse according to the designed firing procedure, and the situation where two or more launching tubes 1 are launched almost simultaneously will not occur, ensuring the firing effect; in addition, the base 4 and the launching tube 1 are detachably clamped and connected, which can conveniently check and maintain the installation quality between the launching tube 1 and the base 4. In addition, this detachable and installable structure also facilitates the arrangement and inspection of the lead wire between the launching tube 1 and the base 4, thus ensuring the firing effect of the fireworks and effectively reducing the explosion risk of the fireworks.

[0020] Among them, this embodiment further includes a lead wire arrangement mechanism. The lead wire arrangement mechanism includes a lead wire groove 7 opened at the bottom of the base 4. The lead wire grooves 7 are distributed between adjacent through holes 5. A lead wire limiting protrusion 8 is fixed at the bottom end of the launching tube 1. The lead wire limiting protrusion 8 extends downward through the through hole 5 and jointly forms a snake-shaped lead wire arrangement mechanism with each lead wire groove 7. In this embodiment, the lead wire groove 7 on the base 4 and the lead wire limiting protrusion 8 at the bottom end of the launching tube 1 can jointly play a role in combing the firing lead wire, facilitating the programming design of the firing procedure, and the above structure greatly reduces the possibility of fire spreading between the lead wires, so that the gunpowder and effect components in each launching tube 1 can be sequentially ignited and launched by the fuse according to the designed firing procedure, ensuring the firing effect.

[0021] Among them, the middle part of the lead wire groove 7 bulges into a truncated groove 11. During implementation, the lead wire needs to be sealed in the truncated groove 11 and the lead wire groove 7 with a glue-limestone mixture, so as to effectively prevent fire spreading.

[0022] In addition, the same launching devices can be combined with each other and combined together by cable ties, glue, or other fixing devices to form fireworks with different total numbers of shots and different firing effects. For example, for 80-shot fireworks, two can be combined into 160 shots, or four can be combined into 320 shots, and different firing effects can be designed at the same time. Secondly, there is another way, which is to design a base with a multiple of the launching tubes, and one base cooperates with multiple combined launching tubes to form fireworks with different total numbers of shots and different effects. Example 2

[0023] The difference between this embodiment and Embodiment 1 is that, as Figures 5-7 shown, the side walls of the top surface 2 extend downward to form a protective cylinder body 10, and the protective cylinder body 10 covers each launch tube 1 together with the base 4 therein, and a plurality of pressure relief grooves 9 and lead ports 12 are provided at the bottom of the protective cylinder body 10.

[0024] Other structures are the same as those in Embodiment 1 and will not be described herein again. Example 3

[0025] The difference between this embodiment and Embodiment 1 is that, as Figures 8-10 shown, the side walls of the base 4 extend upward to form a protective cylinder body 10, and the protective cylinder body 10 wraps each launch tube 1 together with the top surface 2 therein.

[0026] Other structures are the same as those in Embodiment 1 and will not be described herein again.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
