Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] The following is combined Figure 1-4The specific implementation mode of the utility model is described. A firework launching tube fixing structure comprises an upper support 1 and a lower support 2 arranged in a stacked manner. Both the upper support 1 and the lower support 2 comprise a plurality of accommodating grooves 11 arranged and connected by connecting pieces 12. The plurality of accommodating grooves 11 form a plane shape by bending the connecting pieces 12. The accommodating grooves 11 of the upper support 1 and the lower support 2 correspond to each other, and are respectively in inserted fit with the two ends of the firework launching tube. Through the stacked arrangement of the upper support 1 and the lower support 2, double-end fixing of the two ends of the firework launching tube is realized, and a stable support frame is provided. The accommodating grooves 11 are inserting members 132 matching with the size of the end of the launching tube, and through the interference fit of insertion, the friction force and geometric fit are used to ensure that the tube body is fixed without loosening; the connecting pieces 12 arrange and connect the plurality of accommodating grooves 11, and form a specific plane shape through the bent deformed shape, such as array arrangement or curve shape, so that the whole forms an integral plane, and the plurality of accommodating grooves 11 form a projection unit with a shape or pattern. In the connecting structure of the upper and lower supports 2 and the firework launching tube 3, the upper and lower ends of the firework launching tube are supported and limited. On one hand, the overall rigidity and anti-toppling capability during firework launching are enhanced, preventing the tube body from shifting or toppling due to recoil force during the launching process; meanwhile, it is convenient for transportation and storage, because the stacked design and the inserting fit mode of the launching barrel realize convenient disassembly and assembly; in addition, the fixing method simplifies the assembly process, and a user can complete the fixing only by inserting the tube end into the corresponding accommodating groove 11, which does not require additional tools, improves the convenience and safety of use, and is suitable for firework performances of various scales.

[0020] Please refer to Figures 1-2 , the plane shape is a Chinese character, a numeral, a letter or a pattern. The plane shape arranges the position and angle of the accommodating grooves 11 by bending the connecting piece 12 or prefabricating the connecting piece 12 into a specific shape, so as to realize a specific visual shape. The self-structural property or deformability of the connecting piece 12 allows adjusting the relative positions between the accommodating grooves 11 according to requirements, forming a plane layout such as the Chinese character "Xi", the numeral "2024", the letter "LOVE" or a heart-shaped pattern, etc., which improves the artistry and ornamental value of the firework performance.

[0021] In the first implementation mode of the upper and lower supports 2, please refer to Figures 1-2 , the connecting piece 12 is a plastic base plate, and the plastic base plate does not have deformation characteristics. When prefabricated into a specific plane shape, the plastic base plate needs to maintain the required bending curvature, that is, maintain the bending angle, and the overall structural shape of the upper and lower supports 2 cannot be changed structurally.

[0022] In the first implementation mode of the upper and lower supports 2, please refer to Figures 1-2As shown, the connector 12 is a flexible substrate. The upper support 1 and / or the lower support 2 form the planar shape by bending the flexible substrate. The connector 12 is made of a flexible sheet material with plastic deformation capability. Since the connector 12 is a flexible substrate, different planar shapes can be generated by bending the flexible substrate in actual use scenarios. Different patterns, characters, etc., can be formed by bending the flexible substrate according to actual needs. The flexible substrate is made of a flexible sheet material with plastic deformation capability. When the flexible substrate is bent to a target angle by external force, plastic deformation occurs inside, thereby maintaining the bent shape. This allows users to adjust the shape in real time according to on-site needs, improving adaptability.

[0023] Please refer to Figure 2 As shown, the specific material choices for flexible substrates include plastic sheets, thin metal sheets, or fiber-reinforced composite sheets. Plastic sheets offer low cost and high flexibility, while thin metal sheets utilize the ductility and plasticity of metals to provide higher strength and bendability. Fiber-reinforced composite sheets combine the tensile strength of fibers with the flexibility of the matrix to achieve excellent mechanical properties of composite materials. All of these materials can undergo plastic deformation under external forces without easily breaking.

[0024] In the first embodiment of the receiving groove 11 and the connector 12, please refer to Figures 2-3 As shown, the receiving groove 11 and the connecting member 12 are integrally formed, and can be formed into an integrated single component through processes such as injection molding or stamping.

[0025] In the second embodiment of the receiving groove 11 and the connector 12, please refer to Figures 3-4 As shown, the receiving slot 11 and the connector 12 are plugged into each other, which improves the flexibility of the connection between the receiving slot 11 and the connector 12. Users can adjust the number of receiving slots 11 according to the number of tubes to suit custom configurations. In addition, maintenance is simplified. If a single receiving slot 11 is damaged, it can be quickly replaced without affecting the whole. Please refer to Figure 4 As shown, the snap-fit ​​structure includes a plug groove 131 formed on the periphery of the receiving groove 11, and plug-in parts 132 formed at both ends of the connector 12 and plugged into the plug groove 131. The plug groove 131 is a concave opening, and the plug-in part 132 is a matching convex component. Friction locking is achieved by pushing in to ensure connection stability. The plug-in part 132 can provide quick assembly capability, which is convenient to expand or reduce the number of receiving grooves 11.

[0026] Please refer to Figure 2As shown, the bottom of the lower support 2 is connected to a base plate 21. A lead wire hole 111 corresponding to the receiving groove 11 is provided through the base plate 21. A lead wire groove 112 communicating with the lead wire hole 111 is opened on the end face of the base plate 21. Specifically, the bottom of the lower support 2 is provided with a base plate 21, and a lead wire hole 111 and a lead wire groove 112 are designed. The lead wire hole 111 is located at the bottom of the receiving groove 11, and its diameter matches the size of the firework lead wire to facilitate the lead wire to pass through. The lead wire groove 112 forms a groove on the end face of the base plate 21 and communicates with the lead wire hole 111 to guide multiple leads to be arranged in an orderly manner and avoid crossing. The lead wire groove 112 is designed to allow centralized management of leads and support the simultaneous ignition of multiple tubes or individual firework launch tubes to achieve synchronous launch or individual launch effects.

[0027] In the first embodiment of the formation of the base plate 21 and the flexible substrate, please refer to... Figure 2 As shown, the lower support 2 is connected to the base plate 21 by bonding or welding; the connection to the base plate 21 is achieved by shaping the flexible substrate.

[0028] In a second embodiment of the formation of the base plate 21 and the flexible substrate, please refer to... Figure 2 As shown, the base plate 21 is connected to the flexible substrate to form an integrated bendable structure, which can realize the synchronous bending of the base plate 21 and the lower support 2 to form different shapes and patterns.

[0029] Working principle of this utility model: First, based on the visual shapes required for the fireworks display, such as specific text, numbers, or patterns, the connecting piece 12 between the upper support 1 and the lower support 2 is pre-set or bent on-site, so that multiple receiving slots 11 are arranged according to the target planar shape. If the connecting piece 12 uses a flexible substrate, the user can directly adjust the shape by manually bending it. Due to the plastic deformation characteristics of the material, the substrate maintains the bent shape, realizing rapid customization of the shape.

[0030] During assembly, the two ends of the firework launch tubes are inserted into the receiving slots 11 of the upper support 1 and the lower support 2, respectively. The receiving slots 11 and the ends of the launch tubes are fitted with an interference fit, relying on friction and geometric constraints to achieve bidirectional fixation, ensuring that each launch tube is stably erected within the shape plane. If the receiving slots 11 and the connectors 12 are separate plug-in structures 13, the receiving slots 11 can be flexibly added or removed according to the number of launch tubes to adapt to the needs of different scale performances. Adding or removing the receiving slots 11 is only applicable to flexible substrates.

[0031] The base plate 21 at the bottom of the lower support 2 is used to enhance the stability of the overall structure. The lead wire holes 111 on the base plate 21 correspond one-to-one with each receiving groove 11 for threading the firework fuse; the lead wire groove 112 guides and arranges multiple leads in an orderly manner, avoiding the leads from crossing and tangling, and facilitating synchronous ignition or sequential ignition control.

[0032] During launch, the fixed structure effectively resists the launch recoil force by limiting and supporting both ends of the launch tube through the upper and lower supports 2, preventing tube displacement or structural overturning. Its overall design not only enhances the visual artistry of the fireworks launch, but also facilitates quick assembly, disassembly, transportation, and storage with the stacked plug-in structure 13, significantly improving ease of use and safety.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims of this application, they should all fall within the protection scope of this utility model.
