Description

Technical Field

[0001] The utility model relates to the technical field of fireworks, in particular to a stabilizing device for setting off fireworks. Background Art

[0002] When setting off fireworks, it is necessary to ensure that the fireworks are stable in order to achieve the purpose of stabilizing the fireworks. During the setting off process, the fireworks need to be fixed to prevent the fireworks from shifting due to the force of the explosion during setting off, so as to achieve the purpose of setting off fireworks safely.

[0003] Since the gunpowder explosion in fireworks will generate recoil when they are set off, the current stabilizing device is not convenient for reducing the recoil of the fireworks when stabilizing the fireworks, resulting in poor stabilization effect. In addition, the fireworks cannot be rotated during setting off, resulting in poor viewing effect. Utility Model Content

[0004] In order to overcome the above shortcomings, the utility model provides a stabilizing device for fireworks, which can fix the fireworks during ignition and cushion the recoil generated by the fireworks to enhance the stabilizing effect, and can also rotate the fireworks during ignition to enhance the viewing effect.

[0005] The technical solution of the utility model is: a stabilizing device for setting off fireworks, comprising a base, two supporting arms fixedly connected to the base, the two supporting arms being symmetrically arranged, slide rails fixedly connected to the two supporting arms, a stabilizing assembly provided on the supporting arms, the stabilizing assembly being connected to the slide rails, a rotating assembly provided on the supporting arms, the rotating assembly being connected to the stabilizing assembly, the stabilizing assembly being used to stabilize the fireworks, and the rotating assembly being used to rotate the fireworks.

[0006] Furthermore, the stabilizing assembly includes a fixed rod, which is fixedly connected between the two support arms, the fixed rod is rotatably connected to a rotating frame on the rotating frame, the rotating frame is rotatably connected to the rotating rod, the rotating frame is slidably connected to the slide rail, both sides of the rotating frame are fixedly connected to a guide rod, the two guide rods are symmetrically arranged, a sliding frame is slidably connected between the two guide rods, the bottom of the sliding frame is fixedly connected to a moving rod, the moving rod passes through the rotating frame, and a first compression spring is connected between the sliding frame and the rotating frame. Screws are respectively connected to the two sides of the sliding frame by threads, and one side of the two screws is rotatably connected to a splint, and the two splints are respectively slidably connected to the two sides of the sliding frame.

[0007] Furthermore, the rotating assembly includes an overrunning clutch, the overrunning clutch is fixedly connected to the fixed rod, the outer side of the overrunning clutch is fixedly connected to a ring gear, the rotating rod is fixedly connected to a gear, the bottom of the movable rod is fixedly connected to a rack, the rack is meshed with the gear, the gear is meshed with the ring gear, both sides of the rotating frame are slidably connected with sliding blocks, a second compression spring is connected between the two sliding blocks and the rotating frame, and tooth plates are fixedly connected to the two support arms respectively, and the sliding blocks are in contact with the tooth plates.

[0008] Furthermore, the tooth plate is provided with a plurality of oblique teeth.

[0009] The beneficial effects are as follows: 1. When fireworks are set off, the explosion of the fireworks will squeeze the compression spring through the sliding frame, and the compression spring absorbs the recoil force, thereby cushioning the fireworks during the setting off, making the fireworks more stable, thereby enhancing the effect of the setting off. When the sliding frame is reset, the fireworks will rotate to a certain angle, thereby expanding the range of the fireworks setting off, thereby further enhancing the effect of the setting off.

[0010] 2. When the rotating frame rotates, it will drive the sliding block to rotate. The tooth plate squeezes the sliding block, and the second compression spring is compressed. The rotating frame no longer rotates, and the tooth plate no longer squeezes the sliding block. The second compression spring resets and makes the sliding block press against the tooth plate, so that the rotating frame no longer rotates, and the rotating frame is stabilized, thereby improving the safety of the firing.

[0018] Example 1: A stabilizing device for fireworks, such as Figure 1-Figure 5 As shown, it includes a base 1, two support arms 2 are welded on the base 1, and the two support arms 2 are symmetrically arranged. A slide rail 3 is welded on each of the two support arms 2, and the slide rail 3 is used for guiding. A stabilizing component is provided on the support arm 2, and the stabilizing component is connected to the slide rail 3. A rotating component is provided on the support arm 2, and the rotating component is connected to the stabilizing component. The stabilizing component is used to stabilize the fireworks, and the rotating component is used to rotate the fireworks.

[0019] The stabilizing assembly includes a fixed rod 4, which is fixedly connected between the two supporting arms 2, a rotating frame 5 fixedly connected to the fixed rod 4, a rotating rod 51 rotatably connected to the rotating frame 5, and the rotating frame 5 is slidably connected to the slide rail 3. Guide rods 6 are fixedly connected to both sides of the rotating frame 5, and the two guide rods 6 are symmetrically arranged. A sliding frame 7 is slidably connected between the two guide rods 6, and a moving rod 10 is fixedly connected to the bottom of the sliding frame 7. The moving rod 10 passes through the rotating frame 5, and a first compression spring 11 is connected between the sliding frame 7 and the rotating frame 5. The first compression spring 11 is used for buffering, and screws 8 are respectively connected to both sides of the sliding frame 7 by threads, and one side of the two screws 8 is respectively rotatably connected to a splint 9, and the splint 9 is used to fix fireworks. The two splints 9 are respectively slidably connected to the two sides of the sliding frame 7.

[0020] The rotating assembly includes an overrunning clutch 12, which is fixedly connected to the fixed rod 4, and a ring gear 13 is fixedly connected to the outer side of the overrunning clutch 12. A gear 14 is fixedly connected to the rotating rod 51, and a rack 15 is fixedly connected to the bottom of the movable rod 10. The rack 15 is engaged with the gear 14, and the gear 14 is engaged with the ring gear 13. Both sides of the rotating frame 5 are slidably connected with sliding blocks 17, and the tooth plate 17 is used to limit the rotating frame 5. A second compression spring 18 is connected between the two sliding blocks 17 and the rotating frame 5. A tooth plate 16 is fixedly connected to each of the two support arms 2, and the sliding blocks 17 are in contact with the tooth plate 16.

[0021] The tooth plate 16 is provided with a plurality of oblique teeth, and the oblique teeth on the tooth plate 17 are used to prevent reverse rotation.

[0022] When it is necessary to set off fireworks, the staff first places the fireworks on the sliding frame 7 and screws the two screws 8 at the same time so that the two clamping plates 9 clamp the fireworks. Then the staff ignites the fireworks. When the fireworks are set off, recoil will be generated. The recoil of the fireworks will push the sliding frame 7 to move a distance in the direction close to the gear 14. The first compression spring 11 is compressed. The compression of the first compression spring 11 cushions the sliding frame 7 and the fireworks. During the interval of setting off, the first compression spring 11 resets and drives the sliding frame 7 to reset. This is repeated. When the fireworks are set off, the recoil of the fireworks will squeeze the compression spring through the sliding frame 7. The compression spring absorbs the recoil, thereby cushioning the fireworks during setting off, making the fireworks more stable, thereby enhancing the effect of setting off. When the sliding frame 7 moves, it will drive the moving rod 10 to move. The movement of the moving rod 10 will drive the rack 15 to move a distance. The movement of the rack 15 will drive the gear 14 to rotate a certain angle. The rotation of the gear 14 drives the gear ring 13 to idling on the overrunning clutch 12. During the interval of setting off, The first compression spring 11 resets and drives the moving rod 10 to reset. The moving rod 10 resets and drives the gear 14 to rotate through the rack 15. Under the action of the overrunning clutch 12, the gear 14 rotates and revolves along the ring gear 13 by a certain angle. The revolution of the gear 14 drives the rotating frame 5 to rotate through the rotating rod 51. The rotation of the rotating frame 5 drives the sliding frame 7 to rotate through the guide rod 6. The rotation of the sliding frame 7 drives the fireworks to rotate by a certain angle. Repeat this process. When the sliding frame 7 is reset, the fireworks will rotate by a certain angle, thereby expanding the range of the fireworks, thereby further enhancing the effect of the fireworks. When the rotating frame 5 rotates, it will drive the sliding block 17 to rotate. The tooth plate 16 squeezes the sliding block 17. The second compression spring 18 is compressed, and the rotating frame 5 no longer rotates. The tooth plate 16 no longer squeezes the sliding block 17. The second compression spring 18 resets and causes the sliding block 17 to press against the tooth plate 16, thereby preventing the rotating frame 5 from rotating, thereby stabilizing the rotating frame 5, thereby improving the safety of the fireworks. After the fireworks are finished, screw the screw 8 in the opposite direction to remove the fireworks.
