However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] Please see Figure 1-5 This utility model provides an embodiment of a teleprompter device for broadcasting and television engineering, comprising a central rod 1, a base plate 2 fixedly connected to the bottom of the central rod 1, a connecting ring 10 fixedly connected to the outer side of the central rod 1, and multiple sets of connecting plates 13 arranged on the outer side of the connecting ring 10. A threaded telescopic rod 14 is arranged in the middle of each set of connecting plates 13. The threaded telescopic rod 14 is connected to the connecting plate 13 by bolts and locking nuts. The connecting plate 13 and the connecting ring 10 are an integral structure. The multiple threaded telescopic rods 14 are arranged in a ring about the vertical center line of the connecting ring 10. The components are evenly distributed, with the central axis of the central rod 1 coinciding with the vertical center line of the connecting ring 10. The device can be placed on the external horizontal surface via the base plate 2. The central rod 1 provides support for the device. Rotating the threaded telescopic rod 14 allows its bottom end to contact the external horizontal surface, providing auxiliary support for the device, enhancing the stability of the bottom and preventing it from shaking. Loosening the locking nut on the connecting plate 13 allows the threaded telescopic rod 14 to rotate up and down, facilitating the adjustment of the angle between the threaded telescopic rod 14 and the central rod 1.

[0028] In this embodiment, a main platform 3 is fixedly connected to the top of the central rod 1, a motor 4 is fixedly connected to the top of the main platform 3, and a turntable 5 is fixedly connected to the top of the motor 4. The central axis of the chassis 2 coincides with the central axis of the central rod 1. The bottom of the motor 4 is embedded in the top of the main platform 3. The turntable 5 and the motor 4 form a rotating structure. An adjustment frame 6 is fixedly connected to the top of the turntable 5. A rotatable trapezoidal frame 7 is set at the center of the adjustment frame 6. Telescopic columns 8 are fixedly connected to both ends of the trapezoidal frame 7. Springs 9 are sleeved on the outer side of the telescopic columns 8. Multiple telescopic columns 8 are symmetrical about the vertical center line of the trapezoidal frame 7. The central axis of the springs 9 coincides with the central axis of the telescopic columns 8. The ends of multiple telescopic columns 8 are fixedly connected to the same teleprompter display 19. The teleprompter display 19 can display the script of this device, making it convenient to prompt. Starting the motor 4 on the main platform 3 can make the turntable 5 rotate, making it easy to adjust the orientation of the teleprompter display 19, which is convenient for users in different directions to view.

[0029] In this embodiment, rotating shafts 15 are fixedly connected to both sides of the trapezoidal frame 7. The rotating shafts 15 are rotatably connected to the adjusting frame 6. The rotating shafts 15 are symmetrical about the vertical center line of the trapezoidal frame 7 and pass through the side of the adjusting frame 6. A gear 16 is fixedly connected to the end of one of the rotating shafts 15. An electric slide rail 17 is fixedly connected to the top of the turntable 5. A rack 18 is slidably connected to the top of the electric slide rail 17 through a slider. The rack 18 and the gear 16 are meshed. By using the electric slide rail 17 and the slider, the rack 18 can move horizontally, thereby driving the gear 16 to rotate. With the use of the adjusting frame 6 and the rotating shafts 15, the trapezoidal frame 7 can rotate, causing the teleprompter display 19 to rotate slightly up and down, which facilitates the adjustment of the tilt angle of the teleprompter display 19. Furthermore, the sliding range of the electric slide rail 17 can limit the rotation amplitude of the teleprompter display 19 and prevent the teleprompter display 19 from colliding with the turntable 5.

[0030] In this embodiment, multiple sliding rods 11 are fixedly connected to the outer side of the connecting ring 10, and an annular groove 12 is provided at the bottom of the turntable 5. The top of the sliding rods 11 is slidably connected to the annular groove 12. The multiple sliding rods 11 are evenly distributed in a ring about the central axis of the connecting ring 10. The central axis of the annular groove 12 coincides with the central axis of the turntable 5. Through the use of the sliding rods 11 on the connecting ring 10 and the annular groove 12, the stability of the rotation of the turntable 5 and the teleprompter display 19 can be ensured, and the shaking of the teleprompter display 19 can be reduced. By utilizing the elasticity of the spring 9 and the use of the telescopic column 8, the teleprompter display 19 can be damped, preventing large shaking from affecting the user's viewing when adjusting the position of the teleprompter display 19, and further improving the stability of the adjustment of this device.

[0031] Working Principle: When using this device, the base 2 first places it on a horizontal surface. The center rod 1 provides support. Rotating the threaded telescopic rod 14 brings its bottom end into contact with the horizontal surface, providing auxiliary support and enhancing the stability of the device's bottom, preventing it from wobbling. Loosening the locking nut on the connecting plate 13 allows the threaded telescopic rod 14 to rotate up and down, facilitating the adjustment of the angle between the threaded telescopic rod 14 and the center rod 1. The teleprompter display 19 displays the dialogue for easy prompting. The electric slide rail 17 and the slider work together to move the rack 18 horizontally, thereby rotating the gear 16. With the adjustment frame 6 and the rotating shaft 15, the trapezoidal frame 7 rotates, causing the teleprompter display 19 to rotate slightly up and down, facilitating the adjustment of the teleprompter display 19's tilt angle. The sliding range of the electric slide rail 17 limits the rotation amplitude of the teleprompter display 19, preventing collisions between the teleprompter display 19 and the turntable 5.

[0032] Starting the motor 4 on the main platform 3 allows the turntable 5 to rotate, facilitating the adjustment of the orientation of the teleprompter display 19 for users in different directions. The sliding rod 11 on the connecting ring 10, in conjunction with the ring groove 12, ensures the stability of the rotation of the turntable 5 and the teleprompter display 19, reducing the shaking of the teleprompter display 19. The elasticity of the spring 9, in conjunction with the telescopic column 8, provides shock absorption for the teleprompter display 19, preventing significant shaking that could affect the user's viewing experience when adjusting its position, and further enhancing the stability of the device's adjustment.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
