Description

Technical Field

[0001] This utility model relates to a Gatling gun firework. Background Technology

[0002] A Gatling gun is a combination of two or more projectiles installed inside an outer tube (or casing). When ignited, the projectiles produce sound, light, and color effects. A certain firing distance must be maintained between the bottom of the projectiles inside the outer tube and the bottom port of the outer tube. The bottom of the outer tube has a fixed conical handle as a handheld handle or a fixed insertion point. Because the fixed handle occupies a large amount of space, the packaging volume increases, raising storage and transportation costs. To address this, the industry has developed Gatling gun fireworks with retractable handles, such as the "A Gatling Gun Firework" published in Chinese Utility Model Patent Document CN219083909U on May 26, 2023.

[0003] The drawback of the existing technology is that the retractable structure of the handle is relatively complex, and the ease of use and reliability of operation need to be improved. Utility Model Content

[0004] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to provide a Gatling gun firework with a retractable handle, effectively improving its ease of use and operational reliability. To solve this technical problem, the present invention adopts a retractable Gatling gun firework, comprising a projectile assembly, an outer cylinder, and a conical handle. The outer cylinder's inner cavity is characterized by a partition plate fixedly installed in the middle, dividing the inner cavity into an upper and lower cavity. The projectile assembly is disposed in the upper cavity, while the lower cavity accommodates the handle retracted into the outer cylinder. A bottom sleeve is fixedly installed at the bottom end of the outer cylinder, and the bottom sleeve has a through hole for the handle. The inner wall of the through hole has a conical surface that mates with the conical handle. A retaining ring is provided on the inner wall of the bottom end of the through hole. A retaining groove is provided on the outer wall of the handle corresponding to the retaining ring.

[0005] The beneficial effects of this utility model are that during storage and transportation, the handle retracts into the lower cavity of the outer cylinder to reduce the overall length of the product and the packaging volume; when igniting, the handle is pulled outward through the through hole until the slot is engaged with the retaining ring to ignite; it is easy to assemble and use; the retaining ring / slot connection between the conical surface of the hole and the handle makes the handle securely fixed; during storage, the lower cavity provides a stable and reliable space to accommodate the handle; during ignition, the isolation plate and the ignition spacing provided by the lower cavity ensure ignition safety.

[0006] In one embodiment, the top port of the outer cylinder is provided with a top sleeve that circumferentially fixes the outer periphery of the top of the bead-dispensing product assembly, and the bottom end of the bead-dispensing product assembly abuts against the partition plate. The upper and lower parts are reliably fitted together to fix the bead-dispensing product assembly inside the upper cavity of the outer cylinder.

[0007] In one embodiment, the partition plate has a boss underneath that nests with the top end of the handle. The top end of the handle, retracted into the outer cylinder, nests on the boss, providing a fixing function during storage and transportation, and does not affect the ease of pulling the handle out when ready to ignite. Preferably, the boss is a truncated cone.

[0008] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time.

[0021] See appendix Figure 1-6 This describes a specific structure of the present invention. The telescopic Gatling gun firework includes a projectile assembly 1, an outer tube 2, and a conical handle 3. A partition plate 4 is fixedly installed in the middle of the inner cavity of the outer tube 2, dividing the inner cavity of the outer tube 2 into an upper cavity and a lower cavity. The projectile assembly 1 is disposed in the upper cavity, and the lower cavity accommodates the handle that retracts into the outer tube 2. A bottom sleeve 5 is fixedly installed at the bottom end of the outer tube 2. The bottom sleeve 5 has a through hole 6 for the handle 3. The inner wall of the through hole 6 has a conical surface that mates with the conical handle 3. A retaining ring 601 is provided on the inner wall of the bottom end of the through hole 6. A retaining groove 301 is provided on the outer wall of the handle 3 corresponding to the retaining ring 601.

[0022] In the example, the top end of the outer cylinder 2 is provided with a top sleeve 7 that circumferentially fixes the top outer periphery of the bead-dispensing product assembly 1, and the bottom end of the bead-dispensing product assembly 1 abuts against the top of the partition plate 4. The upper and lower parts are reliably fitted together to fix the bead-dispensing product assembly in the upper cavity of the outer cylinder.

[0023] In the example, the isolation plate 4 is provided with a conical frustum 8 that nests and engages with the top port of the handle 3.

[0024] Using the above scheme, during storage and transportation, the handle 3 retracts into the lower cavity of the outer cylinder 2 to reduce the overall length of the product and decrease packaging volume. When igniting, the handle 3 is pulled outward through the hole 6 until the slot 301 engages with the retaining ring 601. Assembly and use are convenient. The retaining ring / slot connection between the hole 6 and the conical surface of the handle 3 ensures reliable fixation of the handle 3. During storage, the lower cavity provides a stable and reliable space to accommodate the handle 3. The top end of the handle 3, retracted into the outer cylinder 2, is nested on the conical frustum 8, providing fixation during storage and transportation, and does not affect the ease of pulling the handle 3 outward when ready to ignite. During ignition, the ignition spacing provided by the lower cavity and the isolation plate 4 effectively protect the igniter, ensuring ignition safety.
