Description

Technical Field

[0001] The utility model relates to the technical field of broadcasting and television equipment, in particular to a multi-angle adjustable broadcasting and television equipment supporting frame. Background Art

[0002] Radio and television equipment refers to various equipment used for the transmission, production or broadcasting of radio and television programs. Radio and television equipment includes cameras, recording equipment, editing equipment, mixing consoles, broadcast consoles, satellite receiving equipment, modems, transmitting equipment, transmission control equipment, etc. The camera is one of the key equipment in radio and television production. It can collect on-site image signals and process and transmit them through subsequent encoding, transmission, decoding and other links. Therefore, cameras are an indispensable part of radio and television equipment.

[0003] For example, a multi-angle camera support for broadcasting and television disclosed in a Chinese patent document (publication number: CN217422779U) "comprises a main pole, a first connecting frame is fixedly mounted on the outer surface of the main pole, a second connecting frame is fixedly mounted on the bottom end of the main pole, a bracket is arranged on the outer surface of the first connecting frame, an inner frame is arranged on the inner side of the bracket, the top end of the bracket is movably connected to the first connecting frame, one end of the inner frame is movably connected to the second connecting frame, a top plate is arranged on the top of the main pole, a plurality of pillars are fixedly mounted on the top of the top plate, a mounting seat is fixedly mounted on the top of the pillars, a turntable is arranged inside the mounting seat, the turntable is rotatably connected to the mounting seat, a mounting hole is opened on the top outer surface of the turntable, a first gear is arranged on the inner bottom end of the mounting seat, and a second gear is arranged on one side of the first gear inside the mounting seat."

[0004] Although the above-mentioned existing multi-angle camera support for broadcasting and television has achieved "by setting a turntable, a first gear, a second gear and a mounting seat, when the angle of the camera needs to be adjusted during shooting, the first knob is turned to drive the turntable to rotate through the first gear, thereby adjusting the angle of the camera; when a fine angle adjustment is required, the second knob can be turned to drive the second gear to rotate through the second knob, and the first gear is driven by the second gear. The second gear is smaller than the first gear, and the turntable will be driven to rotate at a smaller angle during the rotation process, which is convenient for fine adjustment of the camera, greatly increasing the accuracy of the angle adjustment and avoiding affecting the shooting effect of the camera", the existing multi-angle camera support for broadcasting and television does not have the function of adjusting the shooting angle of the camera to achieve depression and elevation, resulting in the following problems:

[0005] Limited viewing angle: The camera cannot be adjusted in pitch and elevation, which means that the camera can only shoot at a fixed horizontal angle, which may lead to failure to capture the required images in some cases, limiting the flexibility and creativity of shooting;

[0006] Poor adaptability: Different scenes and shooting requirements may require different pitch and elevation angles. If the angle cannot be adjusted, the adaptability of the camera will be limited. When shooting at a specific angle, the existing multi-angle camera support for broadcasting and television cannot meet the requirements.

[0007] Shooting effects are affected: The pitch and elevation angles are very important for shooting effects, as they can change the visual effects and perception of the picture; a support frame without angle adjustment will limit the camera's performance capabilities and affect the quality and attractiveness of the shooting results.
