Description

Technical Field

[0001] The invention belongs to the technical field of prompter equipment, and in particular relates to a speech-type teleprompter. Background Art

[0002] The teleprompter displays the contents of the manuscript through a high-brightness display device, and reflects the contents of the display device onto a special coated glass at a 45-degree angle in front of the camera lens, reflecting the lines so that the speaker can face the camera while reading the speech. The speaker, teleprompter, camera and tripod are supported on the same axis, which creates a sense of intimacy that the speaker always faces the audience and improves the quality of the speech.

[0003] The existing teleprompter has a complex structure, looks bulky overall, and has poor stability. A new teleprompter is needed to solve the above problems. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention aims to provide a speech-type teleprompter.

When the motor rotates, the motor shaft of the motor drives the driving gear to rotate, and the driving gear cooperates with the inner ring of the hollow wheel disc to drive the hollow wheel disc to rotate, thereby realizing the retraction and extension of the plastic rod. The conduit serves as a limiting tube for guiding the plastic rod, ensuring that the plastic rod moves along the conduit, and can also prevent the plastic rod from rolling up between the hollow wheel disc and the telescopic sleeve and failing to enter the telescopic sleeve normally.

[0008] The cam is secured to the rear of the wheel and is designed to engage with the support frame of the wheel hub, wherein the two ends of the wheel hub are engaged with the inner wall of the wheel hub and the fixing plate, and the fixing plate and the inner wall of the wheel hub are engaged with each other to ensure the stability of the wheel hub.

[0009] It is further preferred that the passive gear is rotatably connected within the casing, for example, the most conventional and simplest installation method is to fix a limiting rod on the inner wall of the casing, and the inner ring of the passive gear is sleeved on the limiting rod, so that it can be ensured that the passive gear will not shift relative to the driving gear during rotation, and the two ends of the passive gear are limited by the fixed plate and the inner wall of the casing, further ensuring the stable meshing of the passive gear and the driving gear, and the inner ring of the hollow wheel disc is provided with meshing teeth, the driving gear is meshed with the passive gear, and the passive gear is meshed with the meshing teeth, ensuring that the driving gear can drive the passive gear to rotate, and the passive gear can drive the hollow wheel disc to rotate.

The structure of the telescopic sleeve rod is similar to that of a manual telescopic rod, and can be designed with reference to an existing manual telescopic rod, or can directly adopt an existing manual telescopic rod, which can be a two-section structure or a multi-section structure. The specific structure can be selected with reference to the length required to be extended in actual conditions, and is not specifically limited.

[0013] It is further preferred that the outer rod is connected to the box body by a second bolt, which is convenient for loading and unloading, easy to operate, and has a stable connection and is also convenient for subsequent maintenance.

[0014] It is further preferred that a first clamp and a second clamp are provided at one end of the display tray, the first clamp and the second clamp are respectively provided at both ends of the telescopic sleeve rod, one end of the first clamp is fixedly connected to the display tray, and the other end of the first clamp is connected to the second clamp by a third bolt.
