Adjustable audio and video projector

Abstract

The object of the present invention is an adjustable audio and video projector, comprising a roof panel and a projector, and an adjusting device for bravery and projector adjustment is provided between the described projector and the roof panel, and the described adjusting device It includes a first cross bar and a second cross bar, the upper surface of the first cross bar is connected with the roof slab through the connecting slider, the second cross bar is connected with the projector through the connecting block, and the first cross bar and the second cross bar Two vertical adjustment rods are symmetrically arranged on both sides of the center. The rotating gear on the lower surface of the first cross bar is engaged with the side of the vertical adjustment rod. The rotating shaft of the driving motor is connected, and the driving motor is used to adjust the power to realize intelligent operation on the ground, which improves the ease of adjustment and reduces the difficulty of adjustment. At the same time, the rotation angle adjustment is adopted to adapt to audio and video at different heights to achieve the best projection angle. , to improve the projection quality.

Description

technical field [0001] The present invention relates to the field of audio and video, mainly relates to the improvement and design of audio and video projector fixation, and especially relates to an adjustable audio and video projector. Background technique [0002] With the development of the film and television and media industries, people's requirements for audio and video are also gradually increasing. The accuracy of audio and video is getting higher and higher, and the size is getting larger and larger, especially in large conference rooms. In general, conference rooms are relatively large, and the height and angle of audio and video will be adjusted according to different situations. This requires adjustment of the height and angle of the projector, but in general, the position of the projector is relatively high, so it is not necessary to adjust the height and angle of the projector. It is easy to carry out manual adjustment. If manual adjustment is performed in the ...

[0002] With the development of the film and television and media industries, people's requirements for audio and video are also gradually increasing. The accuracy of audio and video is getting higher and higher, and the size is getting larger and larger, especially in large conference rooms. In general, conference rooms are relatively large, and the height and angle of audio and video will be adjusted according to different situations. This requires adjustment of the height and angle of the projector, but in general, the position of the projector is relatively high, so it is not necessary to adjust the height and angle of the projector. It is easy to perform manual adjustment. If manual adjustment is performed in the past, climbing work is required, and the adjustment is difficult.
