Description

Technical Field

[0001] This utility model relates to the field of turntable technology, specifically to a turntable for lottery draws. Background Technology

[0002] Currently, lotteries mostly take various forms, such as computer lotteries and card lotteries. Computer lotteries are a centralized lottery, making it difficult for individuals to fully immerse themselves in the fun. While card lotteries allow everyone to participate, the simple paper cards are unlikely to attract many buyers. Furthermore, regardless of whether it's a computer or card lottery, participants don't feel any lingering interest or lasting impression afterward, and the activities feel rather monotonous. A lottery system using a spinning wheel is needed to address this issue. Utility Model Content

[0020] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Example

[0021] refer to Figures 1 to 3 Embodiment 1 includes a rear support 3, with an outer disk 5 on one side of the rear support 3. A transparent protective cover 1 is provided on the front side of the outer disk 5. A first mounting plate 11 and a second mounting plate 12 are sequentially installed between the rear support 3 and the outer disk 5. A rotating gear 14 is installed at the rear end of the outer disk 5. An inner ring sensor photoelectric sensor 17 and a reset photoelectric sensor 18 are respectively installed on both sides of the rotating gear 14. The inner ring sensor photoelectric sensor 17 and the reset photoelectric sensor 18 are located on both sides of a limiting disk 16. A wheel pointer 23 is installed on the limiting disk 16. A pointer sensor photoelectric sensor 25 is connected to one side of the wheel pointer 23. An intervention component 19 is installed at the bottom of the limiting plate 16, and a stepper motor 20 is installed at the bottom of the intervention component 19. Multiple winning distribution areas 8 are opened on the inner plate 4, and multiple stop pins 9 are fixedly installed at the winning distribution areas 8 on the inner plate 4. The stop pins 9 are distributed in a circle on the inner plate 4. An arc-shaped sleeve 22 is fixedly installed on the limiting plate 16, and a kit 24 is installed inside the arc-shaped sleeve 22. A wheel pointer 23 is sleeved in the middle of the kit 24 and is movably connected through a rotating shaft. A positioning block 13 is fixedly installed at the rear end of the outer plate 5. The first mounting plate 11 and the second mounting plate 12 are connected to the positioning block 13 by bolts.

[0022] In this embodiment, the intervention component 19 can intervene in the winning area of ​​the roulette wheel, ensuring the rationality of the roulette wheel's use and effectively preventing the intermediate rate from being within a reasonable range. Example

[0023] refer to Figure 2 and Figure 4Example 2 further illustrates Example 1. It includes an electromagnetic clutch 6 installed between the inner disk 4 and outer disk 5 on one side of the rear support. A rotating disk 2 is sleeved around the electromagnetic clutch 6. The electromagnetic clutch 6 magnetically attracts the inner disk 4 and outer disk 5 together. Multiple light mounting holes 15 are provided on both the inner disk 4 and outer disk 5, arranged circumferentially around them. Various colors of lights are installed on the light mounting holes 15. The rotation of the rotating disk, combined with the use of lights, enhances the overall quality and effect of the game. A positioning tube 21 is installed in the middle of the limiting disk 16, and the outer end of the limiting disk 16 is fastened by a protective shell 10.

[0024] In this embodiment, the electromagnetic clutch 6 is used to hold the inner disk 4 and the outer disk 5. When the rotating disk 2 rotates the outer disk 5, it will drive the inner disk 4 to rotate together.

[0025] In practical applications, the inner disc 4 of this device is equipped with an intervention component 19, mainly for intervention in the winning area of ​​the roulette wheel. When the winning rate is detected to be higher than the set value, intervention component 19 can be used to intervene and ensure the rationality of the roulette wheel's operation. This effectively prevents the intermediate rate from falling within a reasonable range. The pointer rotates by manually rotating the rotating disc 2 at the outer end of the electromagnetic clutch 6. Since the electromagnetic clutch 6 is used to hold the inner disc 4 and the outer disc 5, when the rotating disc 2 rotates the outer disc 5, it will drive the inner disc 4 to rotate together. The outer disc 5 has greater resistance and will stop earlier, while the inner disc 4 has less resistance. With a relatively small force, the outer disc 5 will continue to rotate under the action of the force while it stops. When the inner disc 4 stops, the pointer on the inner disc 4 will sense different current magnitudes through the pointer sensing photocell 25, the inner ring sensing photocell 17, and the reset photocell 18, thereby determining the position for the lottery. Each person's prize will be located according to the prize distribution area 8, thus giving customers a better lottery experience and more fun. In addition, multiple lights are installed on the inner disc 4 and the outer disc 5. When the rotation of the disc is combined with the use of lights, the quality and effect of the entire game are enhanced, making the entire disc more attractive.
