[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3 , an adjustable bracket for a prompt board, comprising two arc-shaped slides 1 and a prompt board body 15, a base 2 being slidably connected between the two arc-shaped slides 1, two rollers 11 being fixed to the bottom of the base 2 by bolts, the rollers 11 rolling in the arc-shaped slides 1, a rack 3 being welded to one side of one of the arc-shaped slides 1, a first mounting plate 4 being fixed between the inner walls on both sides of the base 2 by bolts, a low-speed motor 5 being fixed to the top of the first mounting plate 4 by bolts, a gear 6 being keyed to the output end of the low-speed motor 5, the gear 6 being meshed with the rack 3, the gear 6 being driven by the low-speed motor 5 to rotate, and then the gear 6 being meshed with the rack 3 to make the rollers 11 rolling in the arc-shaped slides 1, thereby driving the base 2 to move, and then adjusting the prompt direction of the prompt board body 15;

[0022] The top of the base 2 is rotatably connected to a flip support frame 7. The flip support frame 7 is pulled to adjust the tilt angle of the flip support frame 7. Two storage slots 8 are provided on one side of the flip support frame 7. An adjustment bracket 9 is rotatably connected between the inner walls of the two sides of the storage slot 8 through a rotating shaft. The adjustment bracket 9 can be stored in the storage slot 8. Multiple card slots 10 are provided on both sides of the top of the base 2. The bottom end of the adjustment bracket 9 is engaged with the card slot 10. The adjustment bracket 9 is rotated out of the storage slot 8, and then the bottom end of the adjustment bracket 9 is engaged with the card slot 10 to fix the tilt angle of the prompt board body 15. A signal receiver 16 is fixed to the top of the base 2 by bolts. The model of the signal receiver 16 is ZW25.

[0023] Two connecting rods 12 are welded between the inner walls of the two sides of the flip support frame 7. Two sliding sleeves 13 are slidably sleeved on the outer wall of the connecting rod 12. A second mounting plate 14 is fixed to the top between the two sliding sleeves 13 by bolts. The prompt board body 15 is fixed to the second mounting plate 14 by bolts. Pulling the second mounting plate 14 causes the sliding sleeve 13 to move on the connecting rod 12, thereby adjusting the distance between the two second mounting plates 14 to suit the installation of prompt board bodies 15 of different specifications. A limit switch 17 is fixed to both ends of one side of one arc-shaped slide 1 by bolts. The base 2 can contact the limit switch 17 to control the movement of the low-speed motor 5. A third mounting plate 18 is welded to both ends between the two arc-shaped slides 1. A plurality of mounting holes 19 are provided on the top of the third mounting plate 18. Bolts are passed through the mounting holes 19 of the third mounting plate 18 to fix the arc-shaped slide 1. A processor is fixed to the top of the base 2 by bolts. The processor model is ARM9TDMI. The processor is electrically connected to the low-speed motor 5, the signal receiver 16 and the limit switch 17.

[0024] The working principle of this embodiment is as follows: when in use, first, the bolts are passed through the mounting holes 19 of the third mounting plate 18 to fix the arc slide 1, then the second mounting plate 14 is pulled to make the sliding sleeve 13 move on the connecting rod 12, thereby adjusting the distance between the two second mounting plates 14 to suit the installation of the prompt board body 15 of different specifications, and then the prompt board body 15 is fixed on the second mounting plate 14, then the low-speed motor 5 is started, and the gear 6 rotates under the drive of the low-speed motor 5, and then the gear 6 is engaged with the rack 3 to make the roller 11 roll in the arc slide 1, thereby driving the base 2 to move, and then adjusting the prompt direction of the prompt board body 15, and then the flip support frame 7 is pulled to adjust the tilt angle of the flip support frame 7, then the adjustment bracket 9 is rotated out of the storage slot 8, and then the bottom end of the adjustment bracket 9 is engaged with the card slot 10, thereby fixing the tilt angle of the prompt board body 15;

[0025] When the announcer needs to adjust the prompt board body 15 during the broadcast, the signal receiver 16 receives the announcer's voice information and passes the information to the processor for processing. Then, the processor controls the low-speed motor 5 to operate so as to adjust the direction of the prompt board body 15 according to the announcer's needs.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
