Description

Technical Field

[0001] The utility model relates to the field of fireworks launching supports, in particular to a cylindrical fireworks launching support device. Background Art

[0002] Fireworks are widely used in festivals, celebrations and special events. The basic principle of fireworks is to produce explosions of light and color by burning gunpowder with a specific chemical composition. Some of the large cylindrical fireworks need to be supported by fireworks stands to control and adjust the direction and angle of the fireworks.

[0003] Fireworks stands are usually made of metal or plastic and are designed to ensure that fireworks are launched in a safe and controlled manner. The angle adjustment of the fireworks stand is crucial to ensure the safety and viewing effect of the fireworks launch. The fireworks stand needs to manually loosen the fixing device and directly adjust the angle. An angle ruler is set on the fixed side panel of the stand to accurately control the adjustment angle, and then fix it after the adjustment is completed. However, in order to meet the effects of some fireworks launches, the launch angle of the fireworks must be adjusted in real time during the fireworks launch process. Existing fireworks stands are usually difficult to adjust the fireworks launch angle and direction during the launch process. To adjust the launch angle and direction, sometimes people need to adjust it manually at close range, which is undoubtedly dangerous.

[0004] In view of this, in order to overcome the above technical problems, the utility model designs a cylindrical fireworks launching support device to solve the above technical problems. Utility Model Content

[0005] The utility model provides the following technical solutions:

[0006] The utility model provides a tube firework launching support device, comprising: a base, a rotating frame and a fixed tube, the rotating frame comprising a circular chassis and a semicircular supporting frame, the supporting frame being perpendicular to the chassis, the chassis being mounted on the base, and the supporting frame being engraved with scales of 0-90° and 90°-0; a rotating shaft is arranged at the axis of the chassis, the rotating shaft is rotatably connected to the base, the rotating shaft is connected to a driving device, and the rotating frame is driven to rotate by the driving device. The driving device may be a servo motor, the servo motor is mounted at the bottom of the seat surface of the base, and the rotating shaft of the servo motor is coaxially connected to the rotating shaft of the chassis, the rotating frame is driven to rotate by the servo motor, and the driving device is electrically connected to a control system, thereby adjusting the launching direction of the fixed tube firework.

[0007] The fixed tube is used to install the firework tube. A hinge shaft No. 1 is provided on the side of the bottom end of the fixed tube. A hinge hole No. 1 is provided at the center of the support frame. The hinge shaft No. 1 is hinged to the hinge hole No. 1. The fixed tube is driven by the power assembly to rotate around the hinge hole No. 1. A plurality of clamping nuts are provided at the tube mouth of the fixed tube, and non-integral firework tubes of different diameters can be fixed by the clamping nuts. For integral launching fireworks. Instead of being fixed by clamping nuts, the fireworks are directly placed in the fixed tube and then launched. An arc-shaped sliding groove is provided on the support frame, and a sliding roller is provided on the side of the fixed tube, and the sliding roller is slidably connected to the sliding groove. The power assembly drives the fixed tube to rotate around the hinge shaft No. 1, thereby adjusting the launch angle of the fireworks in the fixed tube. The sliding groove limits the sliding trajectory of the sliding roller, thereby limiting the swinging trajectory of the fixed tube within a certain range, and avoiding deviation of the movement trajectory of the fixed tube.

[0008] A plurality of pulleys are installed on the surface of the chassis adjacent to the support frame, and a slide groove is provided on the surface of the base adjacent to the chassis, and the pulley is slidably installed in the slide groove. A gap is left between the chassis and the support frame. The cooperation of the pulley and the slide groove can reduce the friction between the base and the chassis, making the rotation of the rotating frame smoother, and the slide groove can further limit the rotation trajectory of the rotating frame. The reserved gap can eliminate sliding friction between the chassis and the base.

[0009] The power assembly includes a transmission gear, a power gear and a motor. The transmission gear is coaxially fixedly connected with the first hinge shaft. The motor is installed on the chassis. The motor is equipped with a power gear, and the power gear is meshed with the transmission gear. The motor is electrically connected to the control system. The motor drives the driving gear to rotate, and the driving gear drives the transmission gear to rotate, thereby driving the fixed tube to rotate around the first hinge shaft, thereby adjusting the launch angle of the fireworks in the fixed tube.

[0010] The power assembly includes an electric push rod, one end of which is provided with a No. 2 hinge shaft, the other end of which is provided with a No. 3 hinge shaft, the edge of the support frame is provided with a No. 2 hinge hole, the electric push rod is hinged to the No. 2 hinge hole through the No. 2 hinge shaft, the fixed side is provided with a hinge support, the electric push rod is hinged to the hinge support through the No. 3 hinge shaft. The electric push rod is electrically connected to the control system. The swing of the fixed tube is controlled by the extension and retraction of the electric push rod, the fixed tube rotates around the No. 1 hinge hole, and the electric push rod rotates around the No. 2 hinge hole, thereby adjusting the launch angle of the fireworks in the fixed tube.

[0011] Beneficial effects: The existing cylindrical fireworks launching support device usually has a fixed launching angle and a fixed launching direction. The launching angle and direction of the fireworks cannot be adjusted during the launching process. If you want to adjust the launching angle and direction, you must adjust it manually, which will undoubtedly bring danger. The utility model solves this drawback very well. During the fireworks launching process, the launching angle and direction of the fireworks in the fixed cylinder can be adjusted and controlled by remotely controlling the driving device and the power component through a computer, so as to achieve the purpose of adjusting the launching angle and direction of the fireworks during the fireworks launching process.
