Description

Technical Field

[0001] This utility model relates to the field of fireworks launching technology, specifically a fireworks launching device that automatically adjusts the launching angle. Background Technology

[0002] Fireworks, also known as sparklers, fireworks, or firecrackers, are actually similar in structure to firecrackers. Both contain gunpowder and a fuse. To achieve a good performance effect, fireworks and firework shells are filled with a large amount of gunpowder for launching and exploding.

[0003] When setting off fireworks, they need to be stuck in the ground or clamped and fixed with heavy objects to ensure that they do not tip over due to reaction force and cause injury. However, existing fireworks setting devices fix the fireworks by inserting them into placement holes on a bracket. Since the bracket is mostly fixed to the device, the angle of the bracket cannot be adjusted, which means that the fireworks can only be set off at a specific angle, thus affecting the effect of the fireworks.

[0004] Based on this, a fireworks launching device that automatically adjusts the launch angle is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a fireworks launching device that automatically adjusts the launch angle, in order to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fireworks launching device with automatic adjustment of launch angle includes a movable base, a fireworks fixed base above the movable base, a multi-angle adjustment component between the movable base and the fireworks fixed base, two fixing components symmetrically arranged on the fireworks fixed base, a synchronous drive component at the lower end of the two fixing components, and a backstop component on one side of the fixing component.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In one alternative: the movable seat includes a base, the lower end of which is provided with four self-locking casters, a handle is provided on one side of the base, and the base is provided with a mounting slot for installing a multi-angle adjustment component.

[0010] In one alternative: an elastic protective sleeve is provided between the base and the fireworks mounting base, the lower end of the elastic protective sleeve is fixed to the top of the base, and the upper end of the elastic protective sleeve is fixedly connected to the lower end of the fireworks mounting base.

[0011] In one alternative: the multi-angle adjustment assembly includes six electric push rods disposed in the mounting slots, the fixed ends of the electric push rods being hinged to the base, and the output ends of the electric push rods being hinged to the fireworks mounting base.

[0012] In one alternative: the fireworks mounting base includes a support base, on which two sliding grooves are symmetrically provided, and on both sides of each sliding groove are two anti-reverse grooves, and a triangular stop block is provided in the anti-reverse groove.

[0013] In one alternative: the fixing component includes a movable seat slidably disposed in a groove, the movable seat having a clamp at its upper end, an anti-slip tooth on one side of the clamp, and telescopic protective covers on both sides of the movable seat.

[0014] In one alternative: the synchronous drive component includes a screw rod that passes through two sliding grooves, the screw rod is rotatably connected to the support base, the two ends of the screw rod are symmetrically provided with positive and negative threads that are in transmission cooperation with the movable base, and one end of the screw rod is provided with a handwheel.

[0015] In one alternative embodiment: the anti-reverse component includes a limiting rod rotatably connected to the side of the clamping plate opposite to the anti-slip teeth, and the other end of the limiting rod is slidably disposed in the anti-reverse groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a multi-angle adjustment component consisting of six electric push rods to achieve multi-angle adjustment of fireworks, thereby achieving the goal of flexibly adjusting the launch angle of fireworks and significantly improving the diversity of fireworks performance effects, overcoming the defects of fixed support angle and single launch direction in the existing technology.

[0018] 2. This utility model uses a synchronous drive component to drive symmetrically arranged fixing components to move synchronously towards or away from each other. Combined with the anti-slip tooth structure on the clamping plate, it achieves the effect of quickly and stably clamping fireworks of different specifications. At the same time, through the cooperation of the anti-reverse component and the triangular abutment in the anti-reverse groove, a one-way locking mechanism of the fixing components is realized, which achieves the purpose of preventing the clamping from loosening due to vibration during the setting off process.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-3 As shown, an automatic adjustment firework launching device includes a movable base 100, a firework fixing base 200 above the movable base 100, a multi-angle adjustment component 300 between the movable base 100 and the firework fixing base 200, two fixing components 400 symmetrically arranged on the firework fixing base 200, a synchronous drive component 500 at the lower end of the two fixing components 400, and a backstop component 600 on one side of the fixing component 400. In use, the movable base 100 drives the entire device to move, and the synchronous drive component 500 and the fixing component 400 cooperate to fix the firework on the firework fixing base 200. The backstop component 600 locks the fixing component 400, and then the multi-angle adjustment component 300 adjusts the launch angle of the firework.

[0025] In one embodiment, such as Figure 2 As shown, the movable base 100 includes a base 101, with four self-locking casters 102 at the lower end of the base 101. A handle 103 is provided on one side of the base 101. The base 101 has a mounting groove 104 for installing the multi-angle adjustment component 300. An elastic protective sleeve 105 is provided between the base 101 and the fireworks mounting base 200. The lower end of the elastic protective sleeve 105 is fixed to the top of the base 101, and the upper end of the elastic protective sleeve 105 is fixedly connected to the lower end of the fireworks mounting base 200. In use, the movable base 100 is moved to the designated position by pushing the handle 103, and then locked by the brake structure on the self-locking casters 102.

[0026] In one embodiment, such as Figure 2As shown, the multi-angle adjustment component 300 includes six electric push rods 301 disposed in the mounting slot 104. The fixed end of the electric push rod 301 is hinged to the base 101, and the output end of the electric push rod 301 is hinged to the fireworks mounting base 200. The multi-angle adjustment component 300 is based on the principle of a parallel six-degree-of-freedom platform. The six electric push rods 301, which are hinged at both ends, couple six sets of linear motions into three-axis rotation and three-axis translation of the fireworks mounting base through the coordinated change of their independent extension and retraction lengths and inverse kinematics calculations. This achieves spatial pose adjustment of any tilt angle with high precision and high rigidity closed-loop servo control. It is commonly used in precision machining positioning stages, VR experience platforms and other fields. It is an existing technology. In use, the tilt angle of the fireworks mounting base 200 is adjusted by controlling the extension and retraction of the electric push rods 301.

[0027] In one embodiment, such as Figure 3 As shown, the fireworks mounting base 200 includes a support base 201. Two symmetrical grooves 202 are provided on the support base 201. Two anti-reverse grooves 203 are symmetrically provided on both sides of each groove 202. A triangular abutment 204 is provided within each anti-reverse groove 203. The fixing assembly 400 includes a movable seat 401 slidably disposed within the grooves 202. A clamping plate 402 is provided at the upper end of the movable seat 401. Anti-slip teeth 403 are provided on one side of the clamping plate 402. Telescopic protective covers 700 are provided on both sides of the movable seat 401. The synchronous drive component 500 includes a screw 501 that passes through the two grooves 202. The screw 501 is rotatably connected to the support base 201. Symmetrical positive and negative threads are provided at both ends of the screw 501 to engage with the movable seat 401. One end of the screw 501 is equipped with a handwheel 502. The anti-reverse component 600 includes a limiting rod 601 rotatably connected to the opposite side of the clamping plate 402 and the anti-slip tooth 403. The other end of the limiting rod 601 is slidably disposed in the anti-reverse groove 203. During installation, the firework is placed between the two clamping plates 402, and then the handwheel 502 is turned to drive the screw 501 to rotate, so that the movable seat 401 drives the clamping plate 402 to move toward the firework until the firework is clamped. At the same time as the clamping plate 402 moves, the limiting rod 601 moves along the anti-reverse groove 203. When the clamping plate 402 moves to the designated position, the limiting rod 601 abuts against the triangular abutment 204 to prevent the clamping plate 402 from moving in the opposite direction, thereby locking the clamping plate 402.

[0028] The above embodiment discloses a fireworks launching device that automatically adjusts the launch angle. In use, the movable seat 100 is moved to the designated position by pushing the handle 103, and then locked by the brake structure on the self-locking universal wheel 102. Next, the fireworks are placed between the two clamping plates 402, and then the handwheel 502 is turned to drive the screw 501 to rotate, so that the movable seat 401 moves the clamping plate 402 toward the fireworks until the fireworks are clamped. At the same time as the clamping plate 402 moves, the limiting rod 601 moves along the anti-reverse groove 203. When the clamping plate 402 moves to the designated position, the limiting rod 601 abuts against the triangular abutment 204 to prevent the clamping plate 402 from moving in the opposite direction, thereby locking the clamping plate 402. Then, the tilt angle of the fireworks fixing seat 200 is adjusted by controlling the extension and retraction of the electric push rod 301.

[0029] The above description is merely a specific embodiment of this application, but the scope of protection of this application 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 application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
