Abstract

The utility model relates to a headrest typed audio and video display positioning device comprising an audio and video part which is composed of a display, an audio and video playing device, a rear cover, a connecting rod set combined between a back board and a rear cover. The connecting rod set is provided with a bearing. More than one positioning hole and convex block are arranged on the bearing. More than one stopping edge is arranged on the convex blocks. The bearing is provided with a clamp tablet which is provided with more than one positioning hole. A headrest part is also arranged and is composed of a headrest and a back board. Because the positioning hole of the bearing is in screw fixation on the back board and positioning hole of the clamp tablet on the bearing is in screw fixation on the rear cover of the audio and video part, when users adjust the audio and the video part to face upwards or lean downwards, the clamp tablet rotates centering the bearing. In addition, through the positioning edge of the convex block on the bearing withstanding the rear cover of the audio and video part, the degree of facing upward and leaning downdown of the audio and video part is limited, thus reaching the proposal of a headrest typed audio and video display positioning device.
