Description

Technical Field

[0001] This utility model belongs to the field of fireworks display technology, specifically relating to a device for controlling and adjusting the height of fireworks display. Background Technology

[0002] Fireworks, also known as sparklers, fireworks, or firecrackers, are structurally similar to firecrackers, both containing gunpowder and a fuse. To achieve the best performance effect, fireworks and display shells are filled with a large amount of gunpowder for launching and exploding. Preparations are necessary before setting off fireworks, usually involving setting up a launcher.

[0003] The existing Chinese patent with publication number CN220230282U discloses an improved fireworks launcher. However, the existing technical solution has the following drawbacks: Although the solution uses a first handle to rotate a first crossbar, which in turn rotates a second bevel gear, which in turn rotates a first bevel gear, which in turn rotates a screw, the screw then moves a sleeve upwards, thus moving the fireworks launcher and adjusting its height, this adjustment method relies entirely on manual operation of the first handle. This results in a cumbersome and inefficient adjustment process. This purely mechanical adjustment method not only increases the operator's workload but also reduces the device's practicality and user experience due to the lack of automated adjustment functionality, especially limiting its application scenarios requiring frequent height adjustments.

[0004] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a fireworks display height control and adjustment device, including a base. A support box is provided above the base, and a connecting groove is formed through the middle of the bottom surface of the support box. A connecting frame is fixedly connected to the bottom surface of the support box outside the connecting groove, and a bidirectional screw is fixedly installed in the connecting frame. A moving block is threaded onto the bidirectional screw. A connecting block is fixedly connected to the top surface of the moving block through the connecting groove, and a clamping plate is fixedly connected to one side surface of the connecting block. The top surface of the base is fixedly mounted on both sides... The base is equipped with a bearing seat, and a screw is installed in the bearing seat. A threaded cylinder is threadedly connected to the screw, and one end of the threaded cylinder is fixedly connected to a connecting frame. Side plates are fixedly connected to both sides of the top surface of the base on both sides of the screw, and a limit groove is opened on one side surface of the side plate. A limit block is fixedly connected to one side surface of the threaded cylinder, and one end of the limit block extends into the interior of the limit groove. A first motor is fixedly installed at the middle position of the lower top surface of the base, and a rotating rod is fixedly connected to the output end of the first motor. Synchronous pulleys are fixedly installed on the rotating rod and the screw, and a synchronous belt is installed between the synchronous pulleys.

[0006] A mounting plate is fixedly connected to one side of the bottom surface of the connecting frame, and a second motor is fixedly installed on one side of the mounting plate. A second gear is fixedly connected to the output end of the second motor, and the second gear meshes with a first gear fixedly installed on the bidirectional lead screw.

[0007] The connecting block and the connecting groove are rectangular structures, and the top of the connecting block passes through the connecting groove and is slidably connected to the connecting groove.

[0008] Self-locking casters are fixedly installed on both sides of the bottom surface of the base. There are multiple self-locking casters, and the multiple self-locking casters are evenly distributed in pairs on both sides of the bottom surface of the base.

[0009] The limiting block and the limiting groove are rectangular structures, and the limiting block and the limiting groove are slidably connected.

[0010] The number of teeth on the first gear corresponds to the number of teeth on the second gear.

[0011] There are two clamping plates, which are evenly distributed on both sides of the inside of the support box, and the clamping plates are matched with the support box.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention places the fireworks to be set off inside a support box, activates a first motor fixed to the lower surface of the base, drives a synchronous pulley to rotate, and drives a screw to rotate via a synchronous belt. Simultaneously, the circumferential freedom of the threaded cylinder is constrained by the cooperation of a limiting block and a limiting groove, allowing it to move only axially when the screw rotates, thereby driving the support box to rise and fall synchronously. This achieves automated adjustment of the fireworks' setting height, not only reducing the intensity of manual operation but also precisely adapting to the setting needs of different scenarios. It effectively solves the problems of low efficiency and poor adaptability of traditional manual adjustment methods, and greatly improves the ease of operation and applicability of the equipment.

[0014] This invention utilizes a second motor to drive a second gear to mesh with the first gear on a bidirectional lead screw, causing the bidirectional lead screw to rotate. Under the guidance and constraint of the connecting block and the connecting groove, the moving block moves synchronously towards or away from each other along the axial direction of the bidirectional lead screw, thereby driving the clamping plate on the connecting block to perform bidirectional clamping on the fireworks inside the support box. When the clamping plate is in close contact with the outer wall of the fireworks, a stable three-point or multi-point positioning structure is formed, effectively suppressing the vibration or displacement that may occur during the fireworks display, and ensuring the reliability and safety of the display process.

[0026] Please refer to Figures 1-4A fireworks display height control and adjustment device includes a base 1, a support box 2 on top of the base 1, a connecting groove 10 penetrating the middle of the bottom surface of the support box 2, a connecting frame 17 fixedly connected to the bottom surface of the support box 2 outside the connecting groove 10, a bidirectional screw rod 11 fixedly installed in the connecting frame 17, a moving block 5 threadedly connected to the bidirectional screw rod 11, a connecting block 4 fixedly connected to the top surface of the moving block 5 through the connecting groove 10, a clamping plate 3 fixedly connected to one side surface of the connecting block 4, shaft seats fixedly installed on both sides of the top surface of the base 1, a screw rod 12 installed in the shaft seat, a threaded cylinder 13 threadedly connected to the screw rod 12, one end of the threaded cylinder 13 fixedly connected to the connecting frame 17, side plates 6 fixedly connected to both sides of the top surface of the base 1 on the screw rod 12, a limiting groove 7 formed on one side surface of the side plate 6, a limiting block 8 fixedly connected to one side surface of the threaded cylinder 13, one end of the limiting block 8 extending into the limiting groove 7, and the bottom surface of the base 1... A first motor 16 is fixedly installed at the middle position, and a rotating rod is fixedly connected to the output end of the first motor 16. A synchronous pulley 15 is fixedly installed on the rotating rod and the screw 12, and a synchronous belt 14 is installed between the synchronous pulleys 15. The fireworks to be set off are placed in the support box 2, and the support box 2 supports the fireworks. The first motor 16 is started on the lower surface of the top of the base 1. The first motor 16 drives the synchronous pulley 15 to rotate. The synchronous belt 14 drives the screw 12 to rotate. The threaded cylinder 13 on the screw 12 is limited by the limit block 8 and the limit groove 7, so that the threaded cylinder 13 can move on the screw 12. When the threaded cylinder 13 moves, it drives the support box 2 to move, so that the height of the support box 2 can be automatically adjusted. This makes it convenient to adjust the height of the fireworks in the support box 2 according to the actual use needs, reduces the limitations during use, and improves its convenience and work efficiency.

[0027] Please refer to Figure 1 and Figure 2A mounting plate is fixedly connected to one side of the bottom surface of the connecting frame 17, and a second motor 20 is fixedly installed on one side of the mounting plate. A second gear 19 is fixedly connected to the output end of the second motor 20, and the second gear 19 meshes with the first gear 18 fixedly installed on the bidirectional lead screw 11. The first gear 18 and the second gear 19 are matched. The second motor 20 drives the second gear 19 to mesh with the first gear 18 on the bidirectional lead screw 11, causing the bidirectional lead screw 11 to rotate. Under the guidance and constraint of the connecting block 4 and the connecting groove 10, the moving block 5 moves synchronously towards or away from each other along the axial direction of the bidirectional lead screw 11, thereby driving the clamping plate 3 on the connecting block 4 to perform bidirectional clamping on the fireworks in the support box 2. When the clamping plate 3 is in close contact with the outer wall of the fireworks, a stable three-point or multi-point positioning structure is formed, which effectively suppresses the vibration or displacement that may occur during the fireworks display, ensuring the reliability and safety of the display process.

[0028] Please refer to Figure 1 The connecting block 4 and the connecting groove 10 are rectangular structures. The top of the connecting block 4 passes through the connecting groove 10 and is slidably connected to the connecting groove 10, so that the connecting block 4 can move in the connecting groove 10, thereby allowing the clamping plate 3 to move in the support box 2, which facilitates the clamping of the fireworks in the support box 2.

[0029] Please refer to Figure 1 and Figure 3 Self-locking casters 9 are fixedly installed on both sides of the bottom surface of the base 1. There are multiple self-locking casters 9, and the multiple self-locking casters 9 are evenly distributed in pairs on both sides of the bottom surface of the base 1. By pushing the device to move it, and then using the self-locking casters 9, the device can be moved to different positions for use, which helps to improve its flexibility.

[0030] Please refer to Figure 1 The limiting block 8 and the limiting groove 7 are rectangular structures. The limiting block 8 and the limiting groove 7 are slidably connected, which allows the limiting block 8 to move in the limiting groove 7, thereby limiting the threaded cylinder 13 on the screw 12 and maintaining the normal movement of the threaded cylinder 13 on the screw 12.

[0031] Please refer to Figure 1 and Figure 2 The number of teeth on the first gear 18 corresponds to the number of teeth on the second gear 19, which allows it to maintain normal rotation.

[0032] Please refer to Figure 1 There are two clamping plates 3, and the two clamping plates 3 are evenly distributed on both sides of the inside of the support box 2. The clamping plates 3 match the support box 2, so that the clamping plates 3 can move in the support box 2, thereby clamping and fixing the fireworks in the support box 2.

[0033] The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0034] Working principle:

[0035] In use, the fireworks to be set off are placed in the support box 2. The support box 2 supports the fireworks. The first motor 16 on the lower surface of the top of the base 1 is activated. The first motor 16 drives the synchronous pulley 15 to rotate. The synchronous belt 14 drives the screw 12 to rotate. The limiting block 8 and the limiting groove 7 limit the threaded cylinder 13 on the screw 12, allowing the threaded cylinder 13 to move on the screw 12. As the threaded cylinder 13 moves, it also moves the support box 2, thus automatically adjusting the height of the support box 2 according to actual usage needs. The height of the fireworks is adjusted, reducing limitations during use and improving convenience and efficiency. The second motor 20 drives the second gear 19 to mesh with the first gear 18 on the bidirectional lead screw 11, causing the bidirectional lead screw 11 to rotate. Under the guidance and constraint of the connecting block 4 and the connecting groove 10, the moving block 5 moves synchronously towards or away from each other along the axial direction of the bidirectional lead screw 11, thereby driving the clamping plate 3 on the connecting block 4 to clamp the fireworks in the support box 2 in both directions. When the clamping plate 3 is in close contact with the outer wall of the fireworks, a stable three-point or multi-point positioning structure is formed, which effectively suppresses the vibration or displacement that may occur during the fireworks display, ensuring the reliability and safety of the display process.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
