Description

Technical Field

[0001] This utility model relates to the technical field of fireworks fixing devices, specifically to an adjustable fireworks setting device. Background Technology

[0002] Fireworks, also known as sparklers, fireworks, or firecrackers, produce brilliant colors and various patterns when set off. Their structure includes gunpowder and a fuse. If people hold fireworks while they are lit, or if the fireworks are not placed stably during ignition, there is a risk of injury. Therefore, fireworks should be secured with a stable support during the ignition process. Some fireworks fixing devices cannot adjust the size when clamping, but the sizes of fireworks sold on the market vary, making it difficult for fixing devices to clamp and ignite large or small fireworks, which cannot guarantee the stability of the fireworks during ignition and poses a certain risk. Based on this, a fireworks fixing device is now provided that can eliminate the drawbacks of existing devices.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN221425501 U discloses a fixed device for fireworks display, relating to the field of fireworks display equipment technology. The device includes a base plate, a first mounting base mounted on one side of the base plate, and a sliding groove on the other side of the base plate. A protective cylinder is rotatably mounted on the first mounting base, and an adjustment mechanism for adjusting the angle of the protective cylinder is provided within the sliding groove.

[0004] While the aforementioned existing technical solutions achieve the goal of conveniently adjusting the angle of the fireworks, and the movement of the displacement seat can adjust the orientation of the protective cylinder, thereby changing the direction of the fireworks, the buffer mechanism alone cannot completely eliminate the shaking caused by the fireworks spray. This is especially true when placed on uneven muddy ground in suburban or rural areas, where the device is even more unstable. The shaking caused by continuous fireworks spray can easily cause the device to tilt and fall, increasing the danger when setting off fireworks. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to Figures 1-3 This utility model provides a technical solution:

[0022] An adjustable fireworks launching and fixing device includes a base 1. An adjustment groove is formed at the top of the base 1. A first threaded rod 2 is rotatably connected to the inner side of the adjustment groove. An adjustment seat 3 is threadedly connected to the outer wall of the first threaded rod 2. The adjustment seat 3 and the adjustment groove are slidably connected. A linkage assembly is installed on the adjustment seat 3 and the base 1. A fixing cylinder 5 is installed on the linkage assembly. A support and anti-tipping mechanism is installed near the bottom of the base 1. The support and anti-tipping mechanism includes a side support assembly and a plug-in assembly. The side support assembly supports the base 1, and the plug-in assembly increases the stability of the base 1 on muddy ground. In use, the device supports the base 1 through the side support assembly and increases its stability on muddy ground through the plug-in assembly. It has a simple structure and is easy to operate. When placing the base 1, it can provide support to its sides and rear, increasing its stability. When placed on uneven muddy ground in suburban and rural areas, a positioning cylinder 14 can be inserted and a protruding plate 22 can be unfolded to further enhance the positioning effect and prevent the base 1 from tipping over during continuous fireworks launch, ensuring safety during fireworks launch.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the side support assembly includes connecting plates 6 installed at both ends of the outer wall of the base 1. A first support plate 7 is installed at the other end of the connecting plate 6. A second support plate 8 is installed on one side of the outer wall of the base 1. Rubber pads 9 are installed at both ends of the bottom of the base 1 and at the bottom ends of the first support plate 7 and the second support plate 8. The linkage assembly includes a push plate 24 hinged to one side of the adjusting seat 3. A support seat is hinged to the other end of the push plate 24. A first linkage plate 25 is hinged between the top of the support seat and the outer wall of the fixed cylinder 5. A second linkage plate 26 is hinged to the top end of each of the two sets of first support plates 7. A telescopic plate is slidably connected to the inner side of the second linkage plate 26. The other end of the telescopic plate is hinged to the bottom end of the support seat. Next, a third linkage plate 27 is hinged to the other end of the top of the base 1. One end of the third linkage plate 27 is fixedly connected to one side of the outer wall of the fixed cylinder 5. The other end of the outer wall of the base 1 is rotatably connected to an operating rod 4. One end of the operating rod 4 extends to the inner side of the adjustment groove and is fixedly connected to one end of the first threaded rod 2. First, the fireworks are inserted into the inner side of the fixed cylinder 5 for positioning. Then, by holding the operating rod 4, the first threaded rod 2 can be rotated, allowing the adjustment seat 3 to slide in the inner side of the adjustment groove, causing the push plate 24 to deflect. At the same time, the third linkage plate 27, together with the first linkage plate 25 on the support seat, also deflects, causing the angle of the fixed cylinder 5 to change, and the firing angle of the fireworks to change accordingly.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the plug-in assembly includes a vertical plate 10 installed at one end of the top of the second support plate 8. A reset groove is provided on one side of the vertical plate 10, and a reset plate 11 is slidably connected inside the reset groove. Then, the first support plates 7 on both sides and the second support plate 8 behind the base 1 can support the base 1 to prevent the base 1 from tipping over due to the recoil force of the continuous spray of fireworks. When placed on uneven muddy ground in suburbs and rural areas, the pedal 13 can be stepped on to make the reset plate 11 slide inside the reset groove, so that the positioning cylinder 14 moves down and passes through the positioning hole until the reset plate 11 moves to the other side of the inner wall of the reset groove, so that the rubber block 23 fits against the inner wall of the positioning hole. At this time, the tip of the positioning cylinder 14 is inserted into the muddy ground below.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a pedal 13 is installed at one end of the reset plate 11, and a positioning cylinder 14 is installed at the other end of the pedal 13. A movable disc 15 is rotatably connected to the top of the positioning cylinder 14. A knob 16 is installed on one side of the movable disc 15, and a second threaded rod is installed at the other end of the movable disc 15. Slide rods 17 are installed on both sides of the second threaded rod on the inner wall of the positioning cylinder 14. A sliding seat 18 is threadedly connected to the outer side of the second threaded rod. Slide grooves that slide and connect with slide rods 17 are opened at both ends of the top of the sliding seat 18. Inclined grooves are opened at both ends of the bottom outer wall of the sliding seat 18. An insert rod 19 is slidably connected to the inner side of the inclined groove. A limit block 20 is installed on one side of one end of the outer wall of the insert rod 19. A limit groove that slides and connects with the limit block 20 is opened on one side of the inner wall of the inclined groove inside the sliding seat 18. An extension hole that slides and connects with the insert rod 19 is opened on one side of both ends of the outer wall of the positioning cylinder 14. A first fixed seat 21 is installed at the other end of the outer wall of the insert rod 19. A second fixed seat is installed above the extension hole. A protruding plate 22 is hinged between the first fixed seat 21 and the second fixed seat. Multiple sets of extension columns are arranged on one side of the outer wall of the protruding plate 22. A positioning hole is opened at one end of the interior of the second support plate 8. The positioning hole is slidably connected to the positioning cylinder 14. Rubber blocks 23 are installed on both sides of the other end of the outer wall of the positioning cylinder 14. The rubber blocks 23 are slidably connected to the positioning hole. Further, the knob 16 is then pressed to drive the movable plate 15 to rotate, so that the second threaded rod also rotates. In conjunction with the sliding rod 17 and the sliding groove, the sliding seat 18 moves downward, so that the insertion rod 19 and the limiting block 20 on its outer wall extend smoothly along the inclined groove and the limiting groove. While the insertion rod 19 moves, the first fixed seat 21 on it, in conjunction with the second fixed seat, can drive the protruding plate 22 to open up a small space in the soil layer, further increasing the grip and allowing the insertion rod 19 and the extension column to insert into the soil layer, ensuring the stability of the fireworks during continuous spraying.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, both the reset groove and the reset plate 11 have T-shaped cross sections. A first magnetic element 12 is embedded in one side of the reset plate 11, and a second magnetic element that attracts the first magnetic element 12 is embedded in the inner wall of the reset groove. Furthermore, when the positioning cylinder 14 is not used for positioning, the knob 16 can be lifted to move the reset plate 11 to the other side of the inner wall of the reset groove, so that the first magnetic element 12 and the second magnetic element attract each other, temporarily positioning the positioning cylinder 14.

[0027] The implementation principle of the adjustable fireworks launching and fixing device in this application embodiment is as follows: Fireworks are inserted into the fixing cylinder 5 for positioning. Then, holding the operating lever 4 rotates the first threaded rod 2, causing the adjusting seat 3 to slide inside the adjusting groove. This causes the pushing plate 24 to deflect, and simultaneously, the third linkage plate 27, in conjunction with the first linkage plate 25 on the support base, also deflects, changing the angle of the fixing cylinder 5 and thus altering the launching angle of the fireworks. The first support plates 7 on both sides and the second support plate 8 behind the base 1 support the base 1, preventing it from tipping over due to the recoil force of continuous fireworks. When placed on uneven muddy ground in suburban or rural areas, the pedal 13 can be stepped on, causing the reset plate 11 to slide inside the reset groove, allowing the positioning cylinder 14 to move down and pass through the positioning hole until the reset plate 11 moves to the other side of the inner wall of the reset groove. The rubber block 23 is then placed against the inner wall of the positioning hole, and the tip of the positioning cylinder 14 is inserted into the soil below. Then, the knob 16 is engaged to rotate the movable disc 15, causing the second threaded rod to rotate as well. This, along with the sliding rod 17 and the sliding groove, causes the sliding seat 18 to move downwards, allowing the insertion rod 19 and the limiting block 20 on its outer wall to extend smoothly along the inclined groove and the limiting groove. As the insertion rod 19 moves, its first fixed seat 21, in conjunction with the second fixed seat, can cause the convex plate 22 to open up a small space in the soil layer, further increasing the grip and allowing the insertion rod 19 and the extension column to insert into the soil layer, ensuring the stability of the fireworks during continuous spraying. When the positioning cylinder 14 is not used for positioning, the knob 16 can be lifted to move the reset plate 11 toward the other side of the inner wall of the reset groove, causing the first magnet 12 and the second magnet to attract each other, temporarily positioning the positioning cylinder 14.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
