A multi-signal output video playback device with protective structure

Abstract

The invention discloses a multi-signal output video playing device with a protective structure, comprises a base plate and a force receiving plate, wherein the left and right side walls of the base plate are embedded with brackets, the front face of the base plate is fixed with clamping rails, a matching rack is arranged on the side of the clamping rails far away from the horizontal centerline ofthe base plate, insertion plates are fixed on the left and right sides of the surface of the force receiving plate, and the force receiving plate is located on the side of the base plate close to thevertical centerline of the top plate. The multi-signal output video playback device having a protective structure is provided with a plurality of substrates, forming a first carrier structure of the video playback apparatus, the carrier structure is completely used for supporting and fixing the video playing device, the upper and lower ends of the base plate are respectively clamped in the top plate and the base, and the base plate can obtain the displacement action power on the top plate, and the air pipe is externally connected with the air pump body, and the pneumatic telescopic rod is correspondingly expanded and contracted through the control of the air pressure, so as to drag the base plates on the left and right sides to move horizontally.

Problems solved by technology

[0004] The purpose of the present invention is to provide a video playback device with multi-signal output with a protective structure, to solve the existing household video playback device proposed in the above-mentioned background technology, generally referred to as TV, TV set, after installation, its The structure is fixed, cannot be moved, the center of gravity cannot be adjusted, and the angle of the display screen cannot be adjusted. The general video playback device is mostly set as a whole structure, so the flexibility of its own structure is very poor, and the number of interfaces is limited. It is very troublesome, easy to insert wrongly, damage accessories, and waste a lot of time at the same time.
