Description

Technical Field

[0001] The utility model relates to the technical field of fireworks, in particular to a direct contact ignition type environmentally friendly recycled plastic combined fireworks launching component. Background Art

[0002] Combination fireworks have become one of the most active categories in the fireworks market, with demand for them increasing exponentially in recent years. Currently, the launch assembly for combination fireworks in China consists of a launch tube and a base. The tubes are typically produced manually or semi-mechanized, by rolling paper into a tube and then gluing it together. The traditional production of paper tubes for combination fireworks involves numerous steps, is time-consuming and labor-intensive, and the production of paper tubes and paper causes significant environmental problems, such as vegetation damage and papermaking pollution. This has become a bottleneck in the transformation and upgrading of the fireworks industry.

[0003] The plastic launch tube and base are made of plastic particles and molded in one go on a special mold on an injection molding machine. They can be recycled after being ignited and reused after being crushed. This will not cause damage or pollution to the environment, and can also promote the improvement of the level of automated production in the fireworks industry. It is one of the development trends of combined fireworks launch components.

[0004] Existing recycled plastic composite firework launch assemblies typically have a lead slot located on the back of the base. For example, Chinese patent application number 201820172387.2 discloses a novel, environmentally friendly recycled plastic composite firework launch assembly comprising a base and a launch tube. The base is provided with a conical positioning post (a holder) that snaps into place with the bottom of the launch tube. A lead slot is provided on the back of the base, and an axial through-hole is provided at the center of the conical positioning post, communicating with the lead slot. During launch, the fuse in the lead slot is ignited, and the resulting flame escapes through the axial through-hole to the launch tube, igniting the propellant. This type of structure has the disadvantage that the flame is indirectly ignited through the axial through-hole, without the fuse directly contacting the propellant. This can lead to ignition failure. For example, during the production process, the fuse is glued to the lead slot, and the glue may clog the axial through-hole, preventing the flame from escaping and causing ignition failure. If the propellant fails to launch and remains in the launch tube, it not only poses a safety risk for recycling, but also makes the residual propellant difficult to handle during recycling. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a direct contact ignition type environmentally friendly recycled plastic combined fireworks launching assembly, so as to ensure the reliability of ignition, improve the launching effect, and reduce the safety risk of recycling.

[0006] The utility model solves the above problems through the following technical means: a direct contact ignition type environmentally friendly recycled plastic combination firework launching assembly, comprising a base and a launching tube, wherein the base is provided with a holder for being snap-fitted and assembled with the launching tube, and a lead groove is provided on the front side of the base, and the lead groove passes through the holder.

[0007] Furthermore, the top of the holder is provided with an expansion opening connected to the lead groove.

[0008] Furthermore, the diameter of the expansion opening gradually increases from bottom to top.

[0009] Furthermore, the lead slot sections of adjacent card holders are provided with pressure relief ports.

[0010] Furthermore, the base and the card holder are integrally formed.

[0011] Furthermore, the base, holder and launch tube are all made of plastic.

[0012] The beneficial effects of the present invention are as follows: The direct contact ignition type environmentally friendly recycled plastic composite firework launching assembly of the present invention comprises a base and a launching tube, wherein the base is provided with a holder for snap-fitting with the launching tube, and the front of the base is provided with a lead groove, which passes through the holder. In the environmentally friendly recycled plastic composite firework launching assembly of the present application, the lead groove is provided on the front of the base and passes through the holder, enabling the lead fixed in the lead groove to directly contact the propellant in the launching tube, thereby achieving direct contact ignition, ensuring ignition reliability, improving launching effect, and reducing the safety risk of recycling.

[0018] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0019] like Figures 1 to 4As shown, this embodiment discloses a direct contact ignition type environmentally friendly recycled plastic combination firework launching assembly, comprising a base 1 and a launching tube 2. The base is provided with a holder for snap-fitting with the launching tube, and a lead groove 3 is provided on the front of the base, and the lead groove passes through the holder 5; the base and the holder are integrally formed; the base, the holder and the launching tube are all made of plastic. A lead is fixed in the lead groove. With the environmentally friendly recycled plastic combination firework launching assembly of the present application, the lead groove is provided on the front of the base and passes through the holder, and the holder is embedded in the launching tube from the bottom of the launching tube. Therefore, the lead fixed in the lead groove can directly contact the propellant in the launching tube, thereby realizing direct contact ignition, ensuring the reliability of ignition, improving the launching effect, and reducing the safety risk of recycling.

[0020] As a further improvement to the above technical solution, an expansion port 6 connected to the lead groove is provided on the top of the holder, and the diameter of the expansion port gradually increases from bottom to top; the expansion port can enhance the spray state and range of the flame, thereby further ensuring the success of ignition.

[0021] As a further improvement to the above technical solution, the lead slot sections of adjacent holders are provided with pressure relief ports 4. When high-temperature gas flows through the pressure relief ports, the pressure relief ports have a pressure relief effect, thereby improving the safety of the discharge.
