[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please refer to Figure 1 , Figure 2 and Figure 3A fireworks fixing structure includes a fixing seat 1, a support seat 2, and an elastic buckle 3; the fixing seat 1 is provided with a positioning groove 11 and a locking protrusion 12, and the fixing seat 1 is used to connect a mobile carrier; the support seat 2 is slidably installed in the positioning groove 11 and is used to install fireworks 5; the elastic buckle 3 is provided in the support seat 2 and connected to the locking protrusion 12, and is used to lock the support seat 2 in the positioning groove 11.

[0019] In actual use, the fixed base 1 is pre-connected to the mobile carrier; the carrier 2 slides into the positioning groove 11 of the fixed base 1. When the carrier 2 reaches the predetermined position, the elastic buckle 3 engages with the locking protrusion 12, thereby locking the carrier 2 in the positioning groove 11, so that the fireworks 5 installed on the carrier 2 and the mobile carrier are fixedly connected; when disassembling, the elastic buckle 3 is moved to deform it and disengage from the locking protrusion 12, and the carrier 2 can slide out of the positioning groove 11, completing the separation of the fireworks 5 from the mobile carrier.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: the fixed seat 1 is provided with a positioning groove 11 and a locking protrusion 12, the bearing seat 2 can be slidably installed into the positioning groove 11, and the elastic buckle 3 automatically engages with the locking protrusion 12 after the bearing seat 2 is pushed into place, so that the bearing seat 2 is immediately locked. When installing the fireworks 5, there is no need to tighten bolts, wrap tape or fix with clamps. When disassembling, the bearing seat 2 can be unlocked by pulling in the opposite direction, which significantly shortens the disassembly and assembly time and meets the need for quick replacement of fireworks 5.

[0021] Please refer to Figure 2 Furthermore, the elastic latch 3 includes a spring piece 31 and a buckle 32. One end of the spring piece 31 is connected to the support seat 2, and the buckle 32 is installed on the other end of the spring piece 31 and connected to the locking protrusion 12.

[0022] As described above, the elastic latch 3 consists of a spring piece 31 and a snap fastener 32. One end of the spring piece 31 is connected to the support base 2, and the other end is fitted with the snap fastener 32. The snap fastener 32 directly engages with the locking protrusion 12. When the snap fastener 32 is worn or a different elastic force is required, the snap fastener 32 or the spring piece 31 can be replaced separately, without having to replace the entire elastic latch 3, which reduces maintenance costs and improves the interchangeability of parts.

[0023] Please refer to Figure 2 and Figure 3 Furthermore, the fixing base 1 has an avoidance hole 13 at the position corresponding to the buckle 32.

[0024] As described above, the fixing seat 1 has a clearance hole 13 at the position corresponding to the buckle 32. During the locking process, the buckle 32 can be partially sunk into the clearance hole 13 to avoid interference between the buckle 32 and the fixing seat 1, so that the springback stroke of the elastic lock 3 is complete, ensuring that the buckle 32 and the locking protrusion 12 are reliably engaged, and improving the locking stability.

[0025] Furthermore, the spring piece 31 is detachably mounted on the support base 2.

[0026] As described above, the spring 31 is detachably installed on the bearing seat 2. The spring 31 can be replaced by hand on site, which makes it easy to select springs 31 with different stiffness according to the weight of the fireworks 5 or the vibration environment. It also makes it easy to remove the spring 31 during storage or transportation to prevent permanent deformation and extend the service life of the elastic lock 3.

[0027] Please refer to Figure 2 Furthermore, the support base 2 is provided with at least two elastic clamping arms 21, and the firework 5 is clamped between the two elastic clamping arms 21.

[0028] As described above, the support base 2 is provided with at least two elastic clamping arms 21. The firework 5 is clamped between the two elastic clamping arms 21. The radial clamping force of the elastic clamping arms 21 keeps the firework 5 and the support base 2 coaxially positioned, eliminating the need for additional straps or screws, reducing the number of parts while ensuring that the position of the firework 5 on the support base 2 is fixed.

[0029] Furthermore, the free end of the elastic clamping arm 21 is provided with a toggle protrusion 22.

[0030] As described above, the free end of the elastic clamping arm 21 is provided with a prying protrusion 22. The operator can pry the elastic clamping arm 21 outward by pinching the prying protrusion 22 to increase the clamping arm distance, thereby facilitating the insertion or removal of the fireworks 5 and improving the convenience of human-machine operation.

[0031] Furthermore, the elastic clamping arm 21 is provided with a damping element 23, which abuts against the side wall of the firework 5.

[0032] As described above, the elastic clamping arm 21 is equipped with a damping element 23. The damping element 23 abuts against the side wall of the firework 5. The elastic deformation of the damping element 23 absorbs vibration and increases friction, so that the firework 5 remains firmly clamped in the flight vibration environment. At the same time, the damping element 23 can compensate for the manufacturing tolerance of the outer diameter of the firework 5 and expand the range of applicable firework 5 specifications.

[0033] Please refer to Figure 2 and Figure 3 Furthermore, the fixed base 1 is also provided with a quick-release structure 4, which is connected to the mobile carrier.

[0034] As described above, the fixed base 1 is also provided with a quick-release structure 4. The quick-release structure 4 is connected to the mobile carrier. By operating the quick-release structure 4, the fixed base 1 can be quickly separated or combined with the mobile carrier, realizing the quick installation and removal of the fireworks fixing structure on the mobile carrier, which is convenient for on-site module replacement or maintenance.

[0035] Furthermore, the quick-release structure 4 includes a snap-fit ​​base 41 and a snap-fit ​​arm 42. The snap-fit ​​base 41 is disposed on the fixed base 1. One end of the snap-fit ​​arm 42 is rotatably mounted on the snap-fit ​​base 41, and the other end is snapped into the snap-fit ​​base 41. The mobile carrier is snapped between the snap-fit ​​arm 42 and the snap-fit ​​base 41.

[0036] As described above, the quick-release structure 4 includes a snap-fit ​​seat 41 and a snap-fit ​​arm 42. The snap-fit ​​seat 41 is located on the fixed base 1. One end of the snap-fit ​​arm 42 is rotatably mounted on the snap-fit ​​seat 41, and the other end is snapped into the snap-fit ​​seat 41. The mobile carrier is clamped between the snap-fit ​​arm 42 and the snap-fit ​​seat 41. The clamping space can be opened or closed by moving the snap-fit ​​arm 42. The connection or disassembly of the fixed base 1 and the mobile carrier can be completed without tools, and the connection will become tighter with vibration.

[0041] Specifically, in actual use, the fixed base 1 is pre-connected to the mobile carrier; the carrier 2 slides into the positioning groove 11 of the fixed base 1. When the carrier 2 reaches the predetermined position, the elastic latch 3 engages with the locking protrusion 12, thereby locking the carrier 2 in the positioning groove 11, so that the fireworks 5 installed on the carrier 2 are fixedly connected to the mobile carrier; during disassembly, the elastic latch 3 is moved to deform it and disengage from the locking protrusion 12, and the carrier 2 can slide out of the positioning groove 11, completing the separation of the fireworks 5 from the mobile carrier. The fixed base 1 is provided with a positioning groove 11 and a locking protrusion 12. The carrier 2 can slide into the positioning groove 11. After the carrier 2 is pushed into place, the elastic latch 3 automatically engages with the locking protrusion 12, so that the carrier 2 is immediately locked. When installing the fireworks 5, there is no need to tighten bolts, wrap tape or fix it with clamps. When disassembling, the carrier 2 can be unlocked by pulling in the opposite direction, which significantly shortens the disassembly and assembly time and meets the need for quick replacement of fireworks 5.

[0042] Please refer to Figure 2 and Figure 3 In this embodiment, the elastic latch 3 includes a spring piece 31 and a latch 32. One end of the spring piece 31 is connected to the support base 2, and the latch 32 is installed on the other end of the spring piece 31 and connected to the locking protrusion 12. When the latch 32 is worn or a different elastic force is required, the latch 32 or the spring piece 31 can be replaced separately without replacing the entire elastic latch 3, reducing maintenance costs and improving parts interchangeability. Specifically, the fixing base 1 has an clearance hole 13 corresponding to the position of the latch 32, and the latch 32 is in... During the locking process, the buckle 32 can be partially sunk into the clearance hole 13 to avoid interference between the buckle 32 and the fixed seat 1, so that the return stroke of the elastic buckle 3 is complete, ensuring that the buckle 32 and the locking protrusion 12 are reliably engaged, and improving the locking stability. More specifically, the spring piece 31 is detachably installed on the bearing seat 2. In this way, the spring piece 31 can be replaced by hand on site, which makes it easy to select spring pieces 31 with different stiffness according to the weight of the fireworks 5 or the vibration environment. It also makes it easy to remove the spring piece 31 during storage or transportation to prevent permanent deformation and extend the service life of the elastic buckle 3.

More specifically, the elastic clamping arm 21 is provided with a damping element 23, which abuts against the side wall of the firework 5. The elastic deformation of the damping element 23 absorbs vibration and increases friction, so that the firework 5 remains stably clamped even in the vibration environment of flight. At the same time, the damping element 23 can compensate for the manufacturing tolerance of the outer diameter of the firework 5, expanding the range of applicable firework 5 specifications.
