Description

Technical Field

[0001] This utility model relates to the field of fireworks technology, specifically a fireworks launching base. Background Technology

[0002] Fireworks, also known as fireworks or sparklers, are often used in grand ceremonies or performances. Launching a large number of fireworks at the same time can achieve better results. When launching a large number of fireworks at the same time, a launch base can be used to support and fix the fireworks launch tube.

[0003] Currently, some fireworks launchers can ensure that fireworks stand stably on the ground during use. However, the welded state of some fireworks launchers is relatively fixed, making it inconvenient for operators to adjust the angle of the fireworks launchers according to the expected display effect. As a result, the flexibility of some fireworks launchers during use is not very good, and the launch angle of fireworks is relatively limited. Utility Model Content

[0004] The purpose of this invention is to provide a fireworks launching base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireworks launching base, including a support, and further comprising:

[0006] A movable mechanism mounted on the surface of a bracket and lockable, the movable mechanism including a guide component and a positioning component;

[0007] Rotary shaft 1 and several rotating shafts 2 are rotatably connected through both sides of the support. A U-shaped plate 1 is fixedly connected between the two rotating shafts 1. Several rotating shafts 2 are arranged in pairs. A U-shaped plate 2 is fixedly connected between two rotating shafts 2. An extension rod 1 and an extension rod 2 for positioning are fixedly connected above the surfaces of the U-shaped plate 1 and the U-shaped plate 2, respectively.

[0008] A hollow tube welded inside two C-shaped plates and used to store fireworks, wherein a limiting mechanism is installed on the surface of the C-shaped plate, and the surface of the positioning component is provided with a groove that cooperates with the limiting mechanism.

[0009] Preferably, the guide assembly includes a diagonal brace welded to the surface of the bracket, with guide cylinders fixedly connected to both ends of the diagonal brace, a rotating ring rotatably connected to the surface of the guide cylinder, and positioning blocks fixedly connected to both sides of the inner wall of the rotating ring.

[0010] Preferably, the positioning component includes a light rod that slides through the guide cylinder, with a movable disk and a positioning frame fixedly connected to both ends of the light rod, the surface of the positioning frame being in contact with the surface of the bracket, and a plurality of positioning holes being formed on the surface of the positioning frame, the first extension rod and the second extension rod contacting the inner wall of the positioning holes, the surface of the movable disk being slidably connected to the inner wall of the guide cylinder and the rotating ring, the surface of the positioning block contacting the surface of the movable disk, and the groove being formed on the surface of the positioning frame.

[0011] Preferably, the limiting mechanism includes a vertical plate movably connected to both sides of the C-shaped plate. The surface of the vertical plate is provided with a limiting groove that contacts the surface of the extension rod. A vertical plate is fixedly connected to the top of the vertical plate. A slot is provided at the top of the bracket. The bottom of the vertical plate contacts the inner wall of the slot. The surfaces of the vertical plate and the vertical plate are both in contact with the inner wall of the groove.

[0012] Preferably, reinforcing frames are welded to the upper and lower parts of both the first and second C-shaped plates, and the inner wall of the reinforcing frames is in contact with the surface of the hollow cylinder.

[0013] Preferably, a support plate is welded inside the bracket, and the surfaces of both the first and second C-shaped plates are in contact with the surface of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the angles of the first and second shaped plates are adjustable, allowing the launch angle of the fireworks launch tube to be tilted to meet different launch needs. Simultaneously, the base can fix the adjusted first and second shaped plates, ensuring the stability of the hollow tube's angle. This facilitates the launch of fireworks at the desired angle, achieving the desired effect. This solves the problem that some current fireworks launch bases are relatively fixed, lacking flexibility in use, and easily resulting in a single launch path for fireworks, thus affecting the fireworks display effect.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6As shown, a fireworks launching base includes a support 1. A lockable moving mechanism 2 is mounted on the surface of the support 1. The moving mechanism 2 includes a guide assembly 21 and a positioning assembly 22. The guide assembly 21 includes a diagonal brace 211 welded to the surface of the support 1. Guide cylinders 212 are fixedly connected to both ends of the diagonal brace 211. A rotating ring 213 is rotatably connected to the surface of the guide cylinder 212. Positioning blocks 214 are fixedly connected to both sides of the inner wall of the rotating ring 213. When the operator rotates the rotating ring 213, the position of the positioning blocks 214 can be adjusted. The surface of the rotating ring 213 is provided with raised structures, with blank portions between the raised structures. These blank portions correspond to the positioning blocks 214, allowing the operator to determine the position of the positioning blocks 214 by observing the position of the blank portions. The positioning component 22 includes a light rod 221 that slides through the guide cylinder 212. The two ends of the light rod 221 are respectively fixedly connected to a movable disk 222 and a positioning frame 223. The surface of the positioning frame 223 is in contact with the surface of the bracket 1. The surface of the positioning frame 223 is provided with a groove 13 and several positioning holes. Extension rod 1 9 and extension rod 2 11 are in contact with the inner wall of the positioning hole. The positioning hole and extension rod 1 9 and extension rod 2 11 can fix the angle of the C-shaped plate 1 5 and C-shaped plate 2 6. The surface of the movable disk 222 is slidably connected to the inner wall of the guide cylinder 212 and the rotating ring 213. The surface of the positioning block 214 is in contact with the surface of the movable disk 222. The operator rotates the rotating ring 213 and restricts the position of the movable disk 222 through the positioning block 214.

[0025] During use, under the influence of gravity, the positioning block 214 cannot automatically rotate to the top. Therefore, the positioning block 214 can stably limit the moving disk 222, making it difficult for the light rod 221 to move. The position between the rotating ring 213 and the bracket 1 is fixed, and the positioning hole can stably limit the extension rod 1 9 and extension rod 2 11, thereby maintaining the stability of the C-shaped plate 1 5 and C-shaped plate 2 6 and ensuring the stability of the fireworks inside the hollow tube 8.

[0026] The surfaces on both sides of the bracket 1 are rotatably connected by a pivot 3 and several pivots 4. A U-shaped plate 5 is fixedly connected between the pivots 3 on both sides. Several pivots 4 are arranged in pairs. A U-shaped plate 6 is fixedly connected between two pivots 4. Several hollow tubes 8 for storing fireworks are welded inside the U-shaped plates 5 and 6. Reinforcing frames 7 are welded to the upper and lower parts of the U-shaped plates 5 and 6. The inner wall of the reinforcing frame 7 is in contact with the surface of the hollow tube 8. The reinforcing frame 7 is used to increase the stability of the hollow tube 8. An extension rod 9 and an extension rod 11 for positioning are fixedly connected to the upper part of the surfaces of the U-shaped plates 5 and 6, respectively. A limit mechanism 10 is installed on the surface of the U-shaped plate 5.

[0027] The limiting mechanism 10 includes a vertical plate 101 movably connected to both sides of the C-shaped plate 6. The surface of the vertical plate 101 has a limiting groove 102 that contacts the surface of the extension rod 9. A vertical plate 103 is fixedly connected to the top of the vertical plate 101. A handle is installed on the surface of the vertical plate 103. The operator can pull the vertical plate 103 through the handle. At this time, the vertical plate 101 is raised, and the bottom of the inner wall of the limiting groove 102 contacts the bottom of the surface of the extension rod 9. The C-shaped plate 5 can rotate around the pivot 3. A slot 14 is provided at the top of the bracket 1. The bottom of the vertical plate 101 contacts the inner wall of the slot 14. The slot 14 can support the vertical plate 101, thereby controlling the position of the extension rod 9 and ensuring the stability of the angle after the C-shaped plate 5 rotates.

[0028] The surfaces of both the vertical plate 101 and the upright plate 103 are in contact with the inner wall of the groove 13. The groove 13 restricts the position of the vertical plate 101, ensuring the stability of the vertical plate 101 when placed vertically. The upright plate 103 can move the vertical plate 101 inside the groove 13.

[0029] Working principle: When the operator adjusts the angles of the first and second 6 of the C-shaped plate according to the effect of the fireworks display, they can first rotate the rotating ring 213 so that the blank part of its raised structure faces upward, and then pull the positioning frame 223. The positioning frame 223 can drive the light rod 221 and the moving disk 222 to move laterally. The positioning hole releases the limit on the extension rod 9 and extension rod 11, and the operator can then adjust the angle of the second 6 of the C-shaped plate. The support plate 15 is welded inside the bracket 1. The surfaces of the first and second 6 of the C-shaped plate are in contact with the surface of the support plate 15. The support plate 15 can support the tilted C-shaped plate 5 and the second 6 of the C-shaped plate, preventing the rotation angle of the second 6 of the C-shaped plate from being too large and ensuring the subsequent fireworks launch angle. A connecting plate 12 is set between two adjacent second 6 of the C-shaped plate. The surface of the connecting plate 12 is rotatably connected to the surface of the second 6 of the C-shaped plate. The connecting plate 12 can connect the two adjacent second 6 of the C-shaped plate. The two C-shaped plates 6 are connected so that the operator can quickly adjust the angle of the two C-shaped plates 6. At the same time, the operator can pull the handle to lift the vertical plate 101. After the C-shaped plate 5 rotates, the vertical plate 101 descends and engages with the slot 14. The limiting slot 102 controls the angle of the extension rod 9, thereby ensuring the stability of the C-shaped plate 5. After that, the operator pushes the two positioning frames 223 to the opposite side. The moving plate 222 moves and contacts the inner wall of the rotating ring 213. The operator rotates the rotating ring 213, and the positioning block 214 engages with the moving plate 222 to limit the moving plate 222. At this time, the positioning hole on the surface of the positioning frame 223 controls the position of the extension rod 9 and the extension rod 11, further increasing the stability of the C-shaped plates 5 and 6. After the angle of the hollow tube 8 in this base is adjusted, the operator can place the fireworks in the hollow tube 8 and launch them.
