Description

Technical Field

[0001] The utility model relates to the technical field of stage fireworks manufacturing, and in particular to a stage spark manufacturing device. Background Art

[0002] Stage fireworks are usually made by rubbing a grinding disc against a grinding pin to generate sparks, but existing equipment only rubs a single grinding pin, and the amount of sparks generated is small. When facing some large stages, multiple sets of equipment are needed to create sparks, which will inevitably increase the cost of stage layout, and this requires the use of a stage spark making device.

[0003] Patent document CN211513423U discloses a stage spark making device, "including a base, a shell is fixedly installed on the front end of the top surface of the base, two groups of through grooves are opened at the lower ends of the left and right sides of the shell, a slide rail is fixedly installed on the bottom side of the inside of the shell, two groups of sliders are slidably connected on the slide rail, and moving plates are fixedly installed on the top sides of the two groups of sliders, and racks are fixedly installed on the top sides of the moving plates. A motor bracket is fixedly installed on the right side of the rear end of the top surface of the base, and a motor is fixedly installed on the upper end of the motor bracket. The utility model provides a spark making device for stage performances, which effectively utilizes a group of motors, and through the coordinated use of a ratchet mechanism, utilizes the forward and reverse rotation of the motor to generate sparks with intermittent or continuous effects. Compared with the existing spark device, it replaces the need to install and use a swing device to achieve the intermittent spark effect. The structure of the device is simple, compact and practical.

[0004] The above-mentioned equipment uses the ratchet mechanism to produce intermittent or continuous sparks by the forward and reverse rotation of the motor, instead of having to install a swing device to achieve the intermittent spark effect. The structure of the device is simple and compact, and the practicability is strong. However, when the device is used on a larger stage, the amount of sparks produced is difficult to meet, so multiple devices are required to work simultaneously, which will inevitably increase the cost of stage layout, which requires staff to improve their equipment. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the sparks generated by a stage spark making device in the prior art are difficult to meet the needs of a larger stage, thereby providing a stage spark making device.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Reference Figure 1 , Figure 2 and Figure 5 As shown, a stage spark making device comprises: a working box 1, a servo motor 2 is fixedly connected to one side of the working box 1, a first transmission shaft 3 is fixedly connected to the output end of the servo motor 2, and one end of the first transmission shaft 3 is rotatably connected to the inner wall of the working box 1, a gear 4 is fixedly connected to the surface of the first transmission shaft 3, a gear shaft 5 is meshedly connected to the surface of the gear 4, and both ends of the gear shaft 5 are rotatably connected to the inner wall of the working box 1, a transmission belt 6 is meshedly connected to the surface of the first transmission shaft 3, a second transmission shaft 7 is meshedly connected to the inner wall of the transmission belt 6, a grinding disc 8 is fixedly connected to the surface of the second transmission shaft 7, and both ends of the second transmission shaft 7 are rotatably connected to the inner wall of the working box 1;

[0032] When sparks need to be produced, first connect the servo motor 2 to the power supply, and the output end of the servo motor 2 drives the first transmission shaft 3 to rotate. The rotation of the first transmission shaft 3 drives the gear 4 and the transmission belt 6 on the surface to rotate. The rotation of the gear 4 meshes and drives the gear shaft 5 to rotate, and the rotation of the transmission belt 6 drives the second transmission shaft 7 to rotate. The transmission belt 6 is in a taut state. The rotation of the gear shaft 5 and the second transmission shaft 7 drives the grinding disc 8 on the surface to rotate. After the grinding disc 8 rotates, it grinds the grinding needle in the equipment to generate sparks. The gear shaft 5 rotates clockwise, and the second transmission shaft 7 rotates counterclockwise, so that the sparks generated by grinding are ejected toward the top of the equipment.

[0033] Reference Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, both sides of the working box 1 are rotatably connected with movable plates 9, the inner wall of the movable plate 9 is fixedly connected with a telescopic rod 10, one end of the telescopic rod 10 is fixedly connected with a connecting block 11, the inner wall of the connecting block 11 is slidably connected with a slider 12, and one side of the connecting block 11 is threadedly connected with a hand wheel 13;

[0034] First, place the grinding pin on the inner wall of the slider 12, and then turn the hand wheel 13. The hand wheel 13 overlaps one side of the slider 12 by rotation, thereby pushing the slider 12 to move toward the inner wall of the connecting block 11, thereby fixing the grinding pin in the slider 12. During grinding, the spring in the telescopic rod 10 pushes the telescopic rod 10 to extend and retract, and the extension and retraction of the telescopic rod 10 pushes the connecting block 11 to move. The movement of the connecting block 11 drives the slider 12 on the inner wall to move, and the movement of the slider 12 drives the grinding pin on the inner wall to move, thereby pushing the grinding pin to the center position in the working box 1.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a first slide groove 14 is provided on one side of the movable plate 9, a slide rail 15 is slidably connected to the inner wall of the first slide groove 14, a block 16 is fixedly connected to one side of the slide rail 15, and the surface of the block 16 is slidably connected to the inner wall of the first slide groove 14, a second slide groove 17 is provided on one side of the working box 1, and the surface of the block 16 is slidably connected to the inner wall of the second slide groove 17;

[0036] When the movable plate 9 needs to be opened, first move the block 16 to the top of the first slide groove 14 and the second slide groove 17 through the slide rails 15 on both sides, then rotate the two sets of movable plates 9, unfold the two sets of movable plates 9 to both sides, and then replace the grinding needle. After the installation is completed, rotate the two sets of movable plates 9 to overlap the two sides of the working box 1. After the movable plates 9 are overlapped on both sides of the working box 1, the block 16 is inserted into the first slide groove 14, and then the block 16 is pushed, so that the block 16 slides to the bottom of the first slide groove 14 and the second slide groove 17, thereby fixing the movable plate 9 to both sides of the working box 1.

[0037] Reference Figure 1 , Figure 2 and Figure 8 As shown, the top of the movable plate 9 is fixedly connected with a first connecting tube 18, the surface of the first connecting tube 18 is overlapped with a second connecting tube 19, the bottom of the second connecting tube 19 is fixedly connected with a baffle 20, and the surface of the baffle 20 is slidably connected to the inner wall of the working box 1, one side of the working box 1 is fixedly connected with a protective box 21, and both sides of the inner wall of the working box 1 are fixedly connected with arc-shaped guide plates 22;

[0038] When it is necessary to expand the range of spark generation, first push the second connecting cylinder 19. The movement of the second connecting cylinder 19 drives the baffle 20 at the bottom to slide on the top of the inner wall of the working box 1, thereby expanding the gap between the first connecting cylinder 18 and the second connecting cylinder 19, so that more sparks can be sprayed through the gap between the first connecting cylinder 18 and the second connecting cylinder 19, thereby expanding the range of spark generation. The arc guide plate 22 can guide the spray trajectory of the sparks so that most of the sparks are sprayed above the equipment.

[0039] Working principle: before using the device to generate sparks, first move the block 16 to the top of the first slide groove 14 and the second slide groove 17 through the slide rails 15 on both sides, then rotate the two sets of movable plates 9, expand the two sets of movable plates 9 to both sides, and then place the grinding needle on the inner wall of the slider 12, fix the slider 12 to both sides of the grinding needle by rotating the hand wheel 13, and then rotate the two sets of movable plates 9 to reset the movable plates 9, and re-insert the block 16 into the first slide groove 14 and the second slide groove 17 to fix the movable plate 9. When sparks need to be generated, the output end of the servo motor 2 drives the first transmission shaft 3 to rotate, and the rotation of the first transmission shaft 3 drives the gear 4 and the transmission belt 6 on the surface to rotate, thereby meshing and driving the gear shaft 5 and the second transmission shaft 7 to rotate, and the rotation of the gear shaft 5 and the second transmission shaft 7 drives the grinding disc 8 on the surface to rotate. After the grinding disc 8 rotates, the grinding needle in the equipment is polished, and the generated sparks are ejected through the first connecting tube 18 and the second connecting tube 19.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the utility model creation.
