Description

Technical Field

[0001] This utility model relates to a combined fireworks launching base. Background Technology

[0002] Fireworks launch tubes contain propellants and effect components. Once ignited by a fuse, the effect components ascend into the air. Often, multiple launch tubes are combined and launched together. These combinations can be categorized as vertical or fan-shaped. In a vertical combination, the axes of the launch tubes are parallel, and the effect components ascend vertically. In a fan-shaped combination, the lower ends of adjacent launch tubes are close together, while there is a gap between their upper ends, creating a certain angle of inclination (launch deflection angle). The effect components ascend at an angle along this launch deflection angle.

[0003] In the prior art, in order to improve manufacturing efficiency, a multi-tube injection molding structure has emerged, in which multiple launch tubes of combined fireworks are made of plastic into a single component. Examples include "A Plastic Combined Firework Launching Assembly and Fireworks" disclosed in Chinese Patent Document No. CN216523438U on May 13, 2022; "A Spraying Firework Combining Small Fireworks" disclosed in Chinese Patent Document No. CN220418251U on January 30, 2024; and "An Easy-to-Assemble Combined Firework Launching Tube" disclosed in Chinese Patent Document No. CN217131988U on August 5, 2022.

[0004] The drawback of existing technologies is that existing multi-tube injection molding structures are only suitable for vertical combinations and are difficult to complete multi-tube injection molding of fan-shaped combinations. Utility Model Content

[0005] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to provide a multi-tube injection-molded combined fireworks launcher base suitable for fan-shaped combinations. The technical solution adopted by this invention is a deformable fan-shaped combined fireworks launcher base, characterized by comprising an integrally molded elastic panel and several launch tubes arranged in rows and columns. The elastic panel connects to the upper ports of each launch tube; each launch tube has a mounting groove at its lower port for mounting leads; and the elastic panel can be bent from a flat state to an arc state.

[0006] The beneficial effects of this utility model are that, during molding, the elastic panel is in a planar state and the various emitters are arranged in an upright combination, which facilitates the integral injection molding of the elastic panel and several emitters; the elastic panel connects to the upper port of each emitter, and bending the elastic panel into an arc state causes the lower ends of adjacent emitters to move closer together with the deformation of the elastic panel, thus making the emitters arranged in a fan shape; moreover, the mounting grooves at the lower ends of each emitter can be connected with lead wires to fix them in the fan-shaped combination state. It is easy to manufacture and convenient to assemble.

[0007] In one embodiment, a strip-shaped weak zone is provided on the elastic panel between two adjacent rows of emitters. This facilitates the deformation of the elastic panel and the movement of each emitter tube, preventing deformation of the upper end of the emitter tube from affecting the emission of the effect component.

[0008] In one embodiment, the firing tubes located in the same row are connected by reinforcing ribs. Preferably, the upper end of the reinforcing rib is connected to the lower part of the elastic panel. Preferably, the reinforcing rib and the strip-shaped weak area are distributed in parallel. This facilitates the lower ends of each firing tube to move closer together synchronously with the deformation of the elastic panel, preventing deformation of the upper end of the firing tube from affecting the firing of the effect element.

[0021] See appendix Figure 1-5 This illustrates a specific structure of the present invention. The deformable fan-shaped combination fireworks launch base includes an integrally formed elastic panel 1 and several launch tubes 2. The example shows a combination of ninety-six fireworks, with each launch tube 2 arranged in a row of eight rows × twelve tubes per row. The elastic panel 1 connects to the upper port 201 of each launch tube 2; the lower port of each launch tube 2 is provided with a mounting groove 202 for installing a lead wire (not shown in the figure). Generally, the lead wire needs to be fixed with adhesive and the mounting groove 202 needs to be sealed. The lead wire installed in the mounting groove 202 is used to ignite the propellant in each launch tube 2. The combustion gases of the propellant do work inside the tube, thereby launching the effect components inside the launch tube 2 into the air. This is the usual fireworks display technology and will not be described in detail.

[0022] The integrally molded elastic panel 1 and several emission tubes 2 are typically manufactured using injection molding. The elastic panel 1 has the flexibility to bend from a flat state to an arc state (e.g., Figure 4 , 5 (As shown). During molding, the elastic panel is flat and the various emitters are arranged vertically, facilitating the integral injection molding of the elastic panel and the emitters. After molding, the elastic panel 1 is bent into an arc shape. Since the elastic panel 1 connects to the upper port 201 of each emitter 2, the lower ends of adjacent emitters 2 move closer together as the elastic panel 1 deforms, thus arranging the emitters 2 in a fan shape. Then, a long lead wire can be inserted into the mounting groove 201 at the lower end of each emitter 2 for connection, which conveniently fixes it in the fan shape without requiring additional steps for fixing the deformation. Of course, other known methods can also be used to fix the deformation, such as wrapping tape around the outer periphery of the fan-shaped emitters 2, or other fixing methods.

[0023] In the example, a strip-shaped weak area 3 is provided on the elastic panel 1 between two adjacent rows of emitters 2. In the example, the twelve emitters 2 located in the same row are connected by reinforcing ribs 4. In the example, the upper end of the reinforcing rib 4 is connected to the lower part of the elastic panel 1. In the example, the reinforcing rib 4 and the strip-shaped weak area 3 are distributed in parallel. This facilitates the deformation of the elastic panel 1 and the synchronous movement of each row of emitters 2, so that the lower ends of each emitter 2 move closer to each other synchronously with the deformation, preventing the upper port 201 of the emitter 2 from deforming and affecting the emission of the effect component.
