Abstract
Description
Technical Field
[0001] This utility model relates to the field of game turntable technology, specifically a game turntable that is resistant to external interference. Background Technology
[0002] As a popular and well-received entertainment device, the game spinner frequently appears in various entertainment venues and events due to its unique fun and interactivity, becoming a focal point attracting many participants. Whether it's a shopping mall promotion, a holiday celebration, or a party game, the game spinner can always quickly create a lively atmosphere and bring laughter with its simple and easy-to-play features.
[0003] Traditional game roulette designs typically combine a rolling ball with a flat surface. However, when the roulette stops, if the roulette is subjected to accidental impacts, taps, or table vibrations, the rolling ball can easily roll randomly on the flat surface, leading to the final result being easily altered by external forces, thus sparking controversy. Summary of the Invention
[0004] This invention provides a game turntable that is resistant to external interference, which can keep the indicator ball stable when subjected to external impact and prevent it from rolling, thereby effectively preventing positional deviation caused by vibration or collision and further improving the reliability of the results.
[0005] To achieve the above objectives, a game turntable resistant to external interference is provided, comprising a photoelectric sensor mounting bracket. A reset photoelectric sensor is fixedly connected to the inner arc surface of the photoelectric sensor mounting bracket. The reset photoelectric sensor is concave near the center. A turntable body is rotatably connected to the lower inner surface of the photoelectric sensor mounting bracket near the reset photoelectric sensor. The turntable body is a closed circular structure. A disc-shaped surface is formed on the lower inner surface of the turntable body. An indicator ball is set in one of the disc-shaped surfaces. The disc-shaped surface is a circular concave surface with a low center and symmetrically raised edges. The disc-shaped surfaces are arranged circumferentially on the lower inner surface of the turntable body. The disc-shaped surfaces are smooth circular concave surfaces. A transmitting photoelectric sensor is fixedly connected to the upper surface of the photoelectric sensor mounting bracket. A receiving photoelectric sensor is fixedly connected to the upper surface of the photoelectric sensor mounting bracket near the transmitting photoelectric sensor. The turntable body is designed to facilitate the rolling of the indicator ball. The disc-shaped surface is designed to prevent the indicator ball from shifting due to external interference. The indicator ball is designed to work with the turntable body to achieve game entertainment functions. The reset photocell is designed to determine whether the indicator ball is in its initial position. The emitting photocell is designed to emit light signals to detect the movement of the indicator ball. The receiving photocell is designed so that after the indicator ball stops moving, it blocks the light signal emitted by the emitting photocell, thus preventing the receiving photocell from receiving the light signal. This method accurately determines the position of the ball.
[0006] According to the aforementioned anti-interference game turntable, a mechanism housing is fixedly connected to the lower surface of the photoelectric sensor mounting bracket, and a support plate is fixedly connected to one end of the inner surface of the mechanism housing. The mechanism housing is used to install various components, and the support plate is used to install parts.
[0007] According to the aforementioned game turntable designed to prevent external interference, a motor bracket is fixedly connected to the upper surface of the support plate, and a motor is fixedly connected to the inner surface of the motor bracket. The motor bracket is used to mount the motor, and the motor is used to drive the motor drive wheel to rotate.
[0008] According to the aforementioned anti-interference game turntable, a motor drive wheel is fixedly connected to the motor output end, and a rotating shaft lower fixing component is fixedly connected to the upper surface of the support plate near the motor drive wheel. The motor drive wheel is provided to coordinate with the synchronous belt to drive the motor driven wheel to rotate, and the rotating shaft lower fixing component is provided to install the motor driven wheel.
[0009] According to the aforementioned anti-interference game turntable, a motor driven wheel is rotatably connected to the upper surface of the lower fixing member of the rotating shaft, and a synchronous belt is provided on the outer arc surface of the motor driven wheel and the motor driving wheel. The motor driven wheel is provided to drive the rotating shaft to rotate, and the synchronous belt is provided to drive the motor driven wheel to rotate.
[0010] According to the aforementioned anti-interference game turntable, the synchronous belt has a wrap angle greater than 120 degrees between the driven and driven motor pulleys, the diameter of the driven motor pulley is smaller than that of the driven motor pulley, and a rotating shaft is fixedly connected to the upper surface of the driven motor pulley. The rotating shaft is used to connect fixed components to the rotating shaft.
[0011] According to the aforementioned anti-interference game turntable, a fixed component on the rotating shaft is fixedly connected to the upper surface of the rotating shaft body, and the upper surface of the fixed component on the rotating shaft is rotatably connected to the upper surface of the mechanism housing. The fixed component on the rotating shaft is used to connect the turntable connector, and the turntable connector is used to connect the turntable body, thereby driving the turntable body to rotate.
[0012] According to the aforementioned game turntable designed to prevent external interference, a turntable connector is fixedly connected to the upper surface of the fixing member on the rotating shaft, and the upper surface of the turntable connector is fixedly connected to the lower surface of the turntable body.
[0013] The beneficial effects of this invention are as follows: The motor drives the active wheel to rotate, which in turn drives the driven wheel via a synchronous belt, causing the turntable body to rotate synchronously. The indicator ball rolls along the lower inner surface of the turntable under centrifugal force, eventually falling into a disc-shaped surface. Because the disc-shaped surface has a low center and raised edges, it can limit the movement of the rolling ball when subjected to external forces, ensuring accurate and reliable positioning results.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0018] Reference Figures 1 to 4This utility model provides a game turntable designed to prevent interference from external forces. It includes a photoelectric sensor mounting bracket 1, with a reset photoelectric sensor 5 fixedly connected to the inner arc surface of the bracket 1. The reset photoelectric sensor 5 is concave near its center. A turntable body 3 is rotatably connected to the lower inner surface of the bracket 1 near the reset photoelectric sensor 5. The turntable body 3 is a closed circular structure. A disc-shaped surface 15 is formed on the lower inner surface of the turntable body 3. One of the disc-shaped surfaces 15 contains an indicator ball 16. The disc-shaped surface 15 is a circular concave surface with a low center and symmetrically raised edges. The disc-shaped surfaces 15 are arranged circumferentially on the lower inner surface of the turntable body 3 and are smooth circular concave surfaces. A transmitting photoelectric sensor 6 is fixedly connected to the upper surface of the bracket 1, and a receiving photoelectric sensor 4 is fixedly connected to the upper surface of the bracket 1 near the transmitting photoelectric sensor 6. A mechanism housing 2 is fixedly connected to the lower surface of the bracket 1, and a support plate is fixedly connected to one end of the inner surface of the mechanism housing 2. The central area of the disc-shaped surface 15 exhibits a significantly concave shape, while its edges are relatively raised. This unique structural design allows the indicator ball 16 within the disc-shaped surface 15 to effectively limit its rolling range when subjected to external forces, thereby significantly reducing the possibility of the indicator ball 16 rolling outwards due to external interference and improving the accuracy of the final result.
[0019] A driven wheel 13 of a motor is rotatably connected to the upper surface of the lower fixing member 14 of the rotating shaft. A synchronous belt 10 is provided on the outer arc surface of the driven wheel 13 and the driving wheel 12 of the motor. The driving wheel 12 of the motor is fixedly connected to the output end of the motor. The lower fixing member 14 of the rotating shaft is fixedly connected to the upper surface of the support plate near the driving wheel 12 of the motor. A motor bracket 11 is fixedly connected to the upper surface of the support plate. A motor is fixedly connected to the inner surface of the motor bracket 11.
[0020] A turntable connector 7 is fixedly connected to the upper surface of the fixed part 8 on the rotating shaft. The upper surface of the turntable connector 7 is fixedly connected to the lower surface of the turntable body 3. The fixed part 8 on the rotating shaft is fixedly connected to the upper surface of the rotating shaft body 9. The upper surface of the fixed part 8 on the rotating shaft is rotatably connected to the upper surface of the inner part of the mechanism housing 2. The wrap angle of the synchronous belt 10 at the driven wheel 13 and the driving wheel 12 is greater than 120 degrees. The diameter of the driving wheel 12 is smaller than that of the driven wheel 13. The rotating shaft 9 is fixedly connected to the upper surface of the driven wheel 13. The turntable body 3 adopts a completely enclosed circular disc structure, and the overall design is perfectly circular to ensure that the indicator ball 16 remains stable during rolling.
[0021] Working Principle: During use, the motor inside the motor bracket 11 drives the motor drive wheel 12 to rotate, which in turn drives the driven wheel 13 to rotate on the fixed part 14 below the rotating shaft via the synchronous belt 10. This causes the rotating shaft 9 to rotate together, thereby causing the fixed part 8, the turntable connector 7, and the turntable body 3 to rotate synchronously. The rotation of the turntable body 3 generates centrifugal force, causing the indicator ball 16 to roll along the lower inner surface of the turntable body 3. When the motor suddenly stops, the indicator ball 16 eventually stops within a certain dish-shaped surface 15. At this time, the emitting photodetector 6 emits a light signal. Since the indicator ball 16 is located within the dish-shaped surface 15 and blocks the light path, the receiving photodetector 4 will not be able to receive the position signal, thus determining the position of the indicator ball 16. Because the dish-shaped surface 15 has a low center and symmetrically raised edges, even under external interference, the indicator ball 16 is not prone to rolling, thus effectively ensuring the accuracy and reliability of the positioning results.
[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
