Angle adjustable firework launching frame

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] See Figure 1-3 , The present invention provides a technical solution: including a base 1, a shock absorber 2, a stepping motor mounting seat 3, a stepping motor 4, a turntable 5, a hydraulic jack 6, a connecting seat 7, a hinge 8, a launching box 9, a support rod 10. Roller 11, light box 12, control box 13, lamp post 14, electromagnetic board 15, workbench 16, stepping motor switch 17 and launch tube 18, the inside of base 1 is installed with shock absorber 2 and motor mounting seat 3 respectively The stepping motor mounting seat 3 is equipped with a stepping motor 4, the output end of the stepping motor 4 is connected with a turntable 5, the top of the turntable 5 is connected with a worktable 16, and the top of the worktable 16 is respectively provided with a hydraulic jack 6, a lamp post 14 and the electromagnetic board 15, the top of the hydraulic jack 6 is provided with a connecting seat 7, one end of the top of the connecting seat 7 is connected with a hinge 8, one end of the hinge 8 is connected with a launching box 9, and the launching box 9 is provided with a launching tube 18 inside. The bottom of the box 9 is provided with a support rod 10, one end of the support rod 10 is connected with a roller 11, a light box 12 and a control box 13 are respectively installed on the lamp post 14, and the control box 13 is located directly under the light box 12, one side of the base 1 A stepping motor switch 17 is provided.

[0020] Further, the top of the shock absorber 2 is provided with a shock absorbing plate, and the bottom of the shock absorber 2 is provided with a fixed bracket. There are four shock absorbers 2, and they are equally spaced in the interior of the base 1 and arranged inside the base 1. The shock absorber 2, when the firework is launched, the recoil generated is unloaded, so as to protect the launcher from shaking greatly and make the launch more stable.

[0021] Further, incandescent lamps and neon lamps are respectively installed in the light box 12, and the outer shell of the light box 12 is made of transparent materials. The incandescent lamp can provide lighting for the setter, and the neon lamp can remind passing pedestrians.

[0022] Further, the electromagnetic board 15 switch and the light box 12 switch are respectively installed on the control box 13, and the control box 13 is electrically connected to the electromagnetic board 15 and the light box 12 respectively, and the electromagnetic board 15 and the light box 12 are electrically connected, so that the operation launcher is more Convenient and fast.

[0023] Further, there are sixteen launching tubes 18, each of which has the same aperture, and the launching tubes 18 are arranged equidistantly in the launching box 9. The launching tubes 18 have the same aperture, which can make the filled fireworks more stable during launch.

[0024] Further, the stepping motor switch 17 is electrically connected to the stepping motor 4, and the rotation angle of the output end of the stepping motor 4 is three hundred and sixty degrees, and the rotation angle of the output end of the stepping motor 4 can be three hundred and sixty degrees. The direction adjustment is quicker, no need to move the launcher, easy to operate.

[0025] Further, the two ends of the roller 11 are respectively installed with support rods 10, and the roller 11 is made of iron material, the iron roller 11, when the electromagnetic plate 15 is energized, the roller 11 can be adsorbed on the electromagnetic plate 15 to fix the launch box 9 , Make the launching box 9 launch more stable.

[0026] Working principle: When working, the stepping motor 4 and the output end of the stepping motor 4 set in the base 1 rotate to drive the turntable 5, and the turntable 5 drives the worktable 16 to rotate, thereby changing the direction of the launcher, and is set on the worktable 16. The hydraulic jack 6, the hydraulic jack 6 rises, and drives the launching box 9 connected by hinge to change the launching angle of the launching box 9. The roller 11 at the bottom of the launching box 9 rotates, and the electromagnetic board 15 on the control box 13 is turned on. The electromagnetic board 15 Electricity generates magnetic force, exerting a force on the iron roller 11, thereby fixing the launching box 9, the lamp post 14 arranged on the workbench 16, and the lamp post 14 is respectively provided with a light box 12 and a control box 13, by opening the control box The light box 12 on the 13 switch makes the incandescent lamp work and provides lighting for the fireworks. The shock absorber 2 installed in the base 1 uses its own shock absorption effect to unload the recoil generated when the fireworks are released, thereby protecting The launching frame launches stably to ensure the safety of personnel.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
