Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

Examples

Referring to fig. 1 to 6, a tv stand includes a base 1 capable of being fixed to a wall, a fixing plate 2 capable of being fixedly connected to a tv, and a braking structure 3. The base 1 is articulated with the fixed plate 2 through the pivot 4 for both can the relative rotation, specifically speaking, pivot 4 through two lugs 11 on the base 1 with base 1 rotation connection, fixed plate 2 with 4 middle part fixed connection of pivot in the detachable mode. The braking structure 3 includes a brake disc 31, a stopper 32 and an elastic element 33, the brake disc 31 is arranged coaxially with the rotating shaft 4, and the stopper 32 is used for guiding the brake disc 31 to move along the center line of the rotating shaft 4 and limiting the brake disc 31 to rotate. The end surface of the rotating shaft 4 close to one end of the brake disc 31 is provided with concave parts along the circumferential array, the end surface of the brake disc 31 opposite to one end of the concave parts is provided with convex parts along the circumferential array, and the concave parts and the convex parts can be matched to form an interlocking structure; when the brake disc 31 moves axially to press the end face of the rotating shaft 4, the concave part is matched with the convex part, and the rotating shaft is fixed; when the brake disc 31 moves axially away from the end face of the rotating shaft 4, the concave part is separated from the convex part, and the rotating shaft returns to rotate freely. The elastic element 33 is used for axially pressing the brake disc 31 on the rotating shaft 4, so that the concave part and the convex part are matched in a normal state, and the rotating shaft is fixed; when the television needs to rotate, the inclination angle of the television can be adjusted by manually axially moving the brake disc 31, and the elastic element 33 automatically resets after the adjustment is in place, so that the brake disc 31 is axially pressed on the rotating shaft 4 to play a braking role.
