Description

Technical Field

[0001] This utility model relates to the field of fireworks and firecracker launching devices, specifically to an adjustable double-bang launching device. Background Technology

[0002] In traditional fireworks displays, the method of setting off "double-bang" (a type of firecracker) has long had many drawbacks. In the past, people mostly placed them directly on the ground, bricks, or other simple flat surfaces to ignite them. This primitive method poses serious safety risks. Due to the lack of effective fixing and guiding devices, double-bangs are highly likely to tip over or shift during ignition due to instability. If this happens, the explosion direction becomes unpredictable, and the powerful impact and blast fragments can directly threaten the lives of those nearby, as well as easily damage nearby buildings, vehicles, and other property.

[0003] Furthermore, the specifications of firecrackers on the market are not standardized, with significant differences in size, especially in outer diameter, between products from different manufacturers. However, traditional methods of facilitating their ignition are inadequate to accommodate this diversity. When faced with firecrackers of varying outer diameters, users often struggle to find a suitable fixing method. This not only limits the ease of ignition but can also lead to ignition failure or even danger due to insecure fixing. For example, an overly loose fix will cause significant displacement of the firecracker at launch, affecting its flight trajectory; while an overly tight fix may damage the firecracker during installation, also creating a safety hazard. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems and provide an adjustable double-kick launcher. To achieve the above objective, this invention adopts the following technical solution:

[0005] An adjustable double-bang launching device includes a base, a launching tube, bolts, fasteners, a fastening ring, and a connecting plate. The base, as the fundamental support structure of the entire launching device, plays a crucial role in providing a stable surface for the entire device. During the launching process, the base bears and balances the reaction forces and gravity from the launching tube and the double-bang itself, preventing the device from tipping over or shifting unnecessarily due to stress. This ensures the safety and stability of the launching operation and lays the foundation for a successful launch.

[0006] The launch tube is one of the core components of the device, and its main function is to house the firecrackers. Its internal space provides a specific launch channel and guidance for the firecrackers, guiding them to fly in a predetermined direction during launch, effectively reducing deviations in the launch direction, greatly improving the accuracy and reliability of the firecracker launch, and ensuring the smooth progress of the launch process.

[0007] The launching tube comprises an upper tube assembly and a lower tube assembly, which are slidably fitted together. This sliding fit allows the launching tube to be flexibly adjusted according to the actual outer diameter of the firecracker. When encountering firecrackers of different sizes, the upper and lower tube assemblies can slide relative to each other, changing the inner diameter of the launching tube, thereby ensuring that the firecracker is tightly and securely placed inside the launching tube. During launch, this tight fit effectively prevents the firecracker from shaking or shifting inside the tube, ensuring that the firecracker is launched in the predetermined direction and trajectory, improving launch accuracy and safety, and further enhancing the adaptability and versatility of the entire launching device for firecrackers of different sizes.

[0008] The upper cylinder assembly comprises several upper cylinders, which are welded together sequentially to form a closed annular structure. From a structural strength perspective, the welded annular structure provides stable support and strong resistance to deformation for the launch tube. During the launch of the firecracker, significant impact and pressure are generated; the closed annular upper cylinder assembly effectively disperses these forces, preventing excessive localized stress that could damage the launch tube and ensuring the safety and reliability of the launch process. Secondly, while maintaining the integrity of the launch tube, this structural form also facilitates a smooth sliding fit with the lower cylinder assembly. The structure composed of multiple upper cylinders allows for a more uniform change in shape when adjusting the inner diameter, thus better adapting to firecrackers of different outer diameters, improving the versatility and adjustment precision of the device, making the firecracker more securely fixed within the launch tube, and reducing instability factors during launch.

[0009] The lower cylinder assembly comprises several lower cylinders and baffles. The lower cylinders are welded sequentially to form a closed annular structure. The baffles are welded to the inner wall of the lower cylinders, with their tops inserted into the corresponding upper cylinders. The lower cylinder assembly plays a crucial role in the performance of the entire launching device. The sequential welding of the lower cylinders to form a closed annular structure, together with the upper cylinder assembly, constitutes the main frame of the launching tube, providing a stable space for the firecrackers, bearing the forces during launch, and ensuring the overall structural stability. The baffles, welded to the inner wall of the lower cylinders and inserted into the corresponding upper cylinders, act as positioning and support components when adjusting the inner diameter of the launching tube, enhancing the tightness and stability of the fit between the upper and lower cylinder assemblies, and effectively preventing misalignment or separation during adjustment or launch. Simultaneously, after the firecrackers are placed inside the launching tube, the baffles can restrict the radial movement of the firecrackers to a certain extent, further stabilizing their position, ensuring the accuracy of the launch direction, reducing safety hazards caused by firecracker wobbling or displacement, and greatly improving the reliability and safety of the launching device.

[0010] Bolts play a crucial role in connection and adjustment. In terms of structural connection, bolts tightly connect the base, launch tube, and fastening ring into a single structure, ensuring a stable relative position between the components. Simultaneously, utilizing their threaded structure, they allow for precise adjustment of the launch tube's inner diameter to accommodate different outer diameter firecrackers, significantly enhancing the device's versatility and meeting the needs of various firecracker launchers.

[0011] The bolt fastener includes a screw and a nut, which are threaded together. The top of the screw is inserted into a through hole in a connecting plate and threadedly connected to a retaining ring. The screw and nut in the bolt fastener, connected by threads, form an adjustable mechanical structure. When the screw is rotated, due to the relative fixation of the nut, the screw will experience axial displacement. The top of the screw, inserted into the through hole of the connecting plate and threadedly connected to the retaining ring, causes the retaining ring to move along with the screw during rotation. In this way, rotational motion is converted into linear motion, which pulls or pushes the connecting plate, achieving relative sliding between the upper and lower cylinder components of the launch tube. Ultimately, this adjusts the inner diameter of the launch tube to accommodate different sizes of firecrackers, ensuring the stable placement of the firecrackers within the launch tube and guaranteeing the safety and accuracy of the launch.

[0012] The connecting plate connects the launch tube and the bolt fasteners. The welding connection with the launch tube enhances the overall strength and stability of the launch tube, ensuring that the launch tube will not easily deform or be damaged when subjected to external forces, thus guaranteeing the reliability and durability of the device.

[0013] The connecting plate has a through hole in the middle, which is one of the key parts of the entire adjustment mechanism. It provides a channel for the screw to pass through, allowing the screw to establish an effective connection with the fastening ring and nut, thereby realizing the function of adjusting the inner diameter of the launch tube.

[0014] The advantages of this utility model are:

[0015] This invention allows for easy adjustment of the inner diameter of the launch tube to accommodate firecrackers of different outer diameters through the sliding fit of the upper and lower tube components and the adjustment of bolts and fasteners, thus meeting diverse needs. On the other hand, safety is greatly improved. The base provides stable support, and the launch tube structure ensures that the firecrackers are launched in the predetermined direction. The close cooperation of each component reduces the uncertainty of the launch direction, effectively reducing the potential harm to surrounding personnel and property. Attached Figure Description

[0029] The present invention will be described in detail below through specific embodiments to enable a better understanding of the present invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0030] Example 1

[0031] This embodiment discloses an adjustable double-kick launcher.

[0032] like Figure 1-6 As shown, this embodiment includes an adjustable double-kick launcher, comprising a base 1, a launch tube 2, bolt fasteners 3, a fastening ring 4, and a connecting piece 5; the base 1 is welded to the bottom end of the launch tube 2; the bottom end of the bolt fastener 3 is inserted into the center of the base 1, and the top end passes through the connecting piece 5 and is connected to the fastening ring 4; both ends of the connecting piece 5 are welded to the launch tube.

[0033] As the basic support structure of the entire launching device, base 1 bears the important task of providing a stable placement surface for the entire device. During the launch of the firecracker, the reaction force and gravity from the launch tube 2 and the firecracker itself need to be borne and balanced by base 1 to prevent the device from tipping over or shifting unnecessarily due to the force, thereby ensuring the safety and stability of the launch operation and laying the foundation for the successful launch of the firecracker.

[0034] Launch tube 2 is one of the core components of the device. Its main function is to house the firecrackers. Its internal space provides a specific launch channel and guidance for the firecrackers, guiding them to fly in a predetermined direction during launch. This effectively reduces deviations in the launch direction, greatly improves the accuracy and reliability of the firecracker launch, and ensures the smooth progress of the launch process.

[0035] The bolt fastener 3 plays a crucial role in connection and adjustment. In terms of structural connection, the bolt fastener 3 tightly connects the base 1, the launching tube 2, and the fastening ring 4 into a single integrated structure, ensuring a stable relative position between the components. Simultaneously, utilizing its own threaded structure, it enables precise adjustment of the inner diameter of the launching tube 2 to accommodate different outer diameter firecrackers, significantly enhancing the device's versatility and meeting the needs of various firecracker launchers.

[0036] The fastening ring 4, in close engagement with the bolt fastener 3, plays a crucial role in transmission and fixation during the adjustment of the inner diameter of the launch tube 2. When the bolt fastener 3 is rotated, the fastening ring 4 moves accordingly, thereby driving the connecting piece 5 to move, ultimately changing the inner diameter of the launch tube 2. During the launch of the double-bang firecracker, the fastening ring 4 effectively maintains the adjusted state of the launch tube 2, preventing it from loosening or changing its inner diameter due to external factors such as vibration, thus ensuring the stability of the launch process.

[0037] The connecting piece 5 connects the launching tube 2 and the bolt fastener 3. By welding the connecting piece to the launching tube 2, the overall strength and stability of the launching tube 2 are enhanced, ensuring that the launching tube 2 will not easily deform or be damaged when subjected to external forces, thus guaranteeing the reliability and durability of the device.

[0038] Furthermore, the launching tube 2 includes an upper tube assembly 21 and a lower tube assembly 22; the upper tube assembly 21 and the lower tube assembly 22 are in sliding engagement.

[0039] The launching tube 2 consists of an upper tube assembly 21 and a lower tube assembly 22, and their sliding fit design is of great significance. This sliding fit allows the launching tube 2 to be flexibly adjusted according to the actual outer diameter of the firecracker. When encountering firecrackers of different sizes, the upper tube assembly 21 and the lower tube assembly 22 can slide relative to each other, changing the inner diameter of the launching tube 2, thereby ensuring that the firecracker can be placed tightly and securely inside the launching tube 2. During launch, this tight fit effectively prevents the firecracker from shaking or shifting inside the tube, ensuring that the firecracker is launched in the predetermined direction and trajectory, improving the accuracy and safety of the launch, and further enhancing the adaptability and versatility of the entire launching device for firecrackers of different sizes.

[0040] The upper cylinder assembly 21 comprises several upper cylinders 211; these upper cylinders 211 are welded sequentially to form a closed annular structure. From a structural strength perspective, the welded annular structure provides stable support and strong resistance to deformation for the launch tube 2. During the launch of the firecracker, significant impact and pressure are generated. The closed annular upper cylinder assembly 21 effectively disperses these forces, preventing excessive local stress that could damage the launch tube and ensuring the safety and reliability of the launch process. Furthermore, while ensuring the integrity of the launch tube 2, this structural form also facilitates a good sliding fit with the lower cylinder assembly 22. The structure composed of multiple upper cylinders 211 allows for a more uniform change in shape when adjusting the inner diameter, thus better adapting to firecrackers with different outer diameters, improving the versatility and adjustment precision of the device, making the firecracker more securely fixed within the launch tube 2, and reducing instability factors during launch.

[0041] Furthermore, the lower cylinder assembly 22 includes a plurality of lower cylinders 221 and baffles 222; the plurality of lower cylinders 221 are welded in sequence to form a closed annular structure; the baffles 222 are welded to the inner wall of the lower cylinders 221 and the top end is inserted into the corresponding upper cylinder 211.

[0042] The lower cylinder assembly 22 plays a crucial role in the performance of the entire launching device. Several lower cylinders 221 are welded in sequence to form a closed ring structure, which together with the upper cylinder assembly 21 constitutes the main frame of the launching tube, providing a stable housing space for the double kicks, bearing the force during launch, and ensuring the stability of the overall structure.

[0043] The baffle plate 222 is welded to the inner wall of the lower cylinder 221 and inserted into the corresponding upper cylinder 211. When adjusting the inner diameter of the launch tube 2, the baffle plate 222 can serve as a positioning and support component, enhancing the tightness and stability of the upper and lower cylinder components and effectively preventing misalignment or separation during adjustment or launch. Simultaneously, after the double-bang kicker is placed inside the launch tube 2, the baffle plate 222 can limit the radial movement of the kicker to a certain extent, further stabilizing its position, ensuring the accuracy of the launch direction, reducing safety hazards caused by kicker wobbling or displacement, and greatly improving the reliability and safety of the launch device.

[0044] The connecting piece 5 has a through hole 51 in the middle. The through hole 51 in the middle of the connecting piece 5 is one of the key parts of the entire adjustment mechanism. It provides a passage for the screw 31 to pass through, so that the screw 31 can establish an effective connection with the fastening ring 4 and the nut 32, thereby realizing the function of adjusting the inner diameter of the launching tube 2.

[0045] Furthermore, the bolt fastener 3 includes a screw 31 and a nut 32; the screw 31 and the nut 32 are threaded together; the top of the screw 31 is inserted into the through hole 51 and is threaded together with the fastening ring 4.

[0046] The screw 31 and nut 32 in the bolt fastener 3 are connected by threads, forming an adjustable mechanical structure. When the screw 31 is rotated, the screw 31 will have axial displacement due to the relative fixation of the nut 32. The top of the screw 31 is inserted into the through hole 51 of the connecting piece 5 and is threadedly connected to the fastening ring 4. In this way, the rotational motion is converted into linear motion, which in turn pulls or pushes the connecting piece 5, realizing the relative sliding between the upper cylinder assembly 21 and the lower cylinder assembly 22 of the launch tube 2. Ultimately, this achieves the purpose of adjusting the inner diameter of the launch tube 2 to accommodate different specifications of firecrackers, ensuring the stable placement of the firecrackers inside the launch tube and guaranteeing the safety and accuracy of the launch.

[0047] It is important to note that before launching, the device should first be placed in a stable, open area that meets safety regulations. Ensure that the base 1 is in good contact with the ground and is placed stably to provide a solid foundation for subsequent operations.

[0048] Next, the inner diameter of the launching tube 2 is adjusted according to the outer diameter of the firecracker to be launched. By rotating the screw 31 of the bolt fastener 3, the threaded engagement of the screw 31 with the nut 32 and its threaded connection with the fastening ring 4 causes the fastening ring 4 to move up and down. Since the fastening ring 4 is connected to the launching tube 2 through the connecting piece 5, the two ends of the connecting piece 5 are welded to the launching tube 2, and the through hole 51 in the middle allows the screw 31 to pass through. Therefore, the movement of the fastening ring 4 will drive the connecting piece 5, thereby causing the upper tube assembly 21 of the launching tube 2 to slide relative to the lower tube assembly 22. Together, they achieve precise adjustment of the inner diameter of the launching tube 2 until it can tightly fit the outer diameter of the firecracker.

[0049] Then, carefully place the firecracker into the launch tube 2 with its inner diameter adjusted, ensuring that the firecracker is placed stably and in the center of the launch tube 2, so that it is in full contact with the inner wall of the launch tube 2. Use the structure of the launch tube 2 to stabilize the firecracker and prevent it from shifting before launch.

[0050] Finally, after ensuring the surrounding environment is safe and personnel are at a safe distance, the fuse of the firecracker is lit to initiate the launch procedure. During the launch, the launch tube 2 guides the firecracker to fly in the predetermined direction, while the base 1 stably supports the entire device, bearing the reaction force generated by the launch, ensuring a smooth launch process and reducing safety risks.

[0051] The specific embodiments of this utility model have been described in detail above, but they are merely examples, and this utility model is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to this utility model are also within the scope of this utility model. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of this utility model should be covered within the scope of this utility model.
