1. A display apparatus including a display main body having a front side for displaying image information and a hanger connected to a rear side of the display main body, the hanger comprising:

a fixing plate for fixing to an external bracket or a wall;

a rotation shaft connected to the fixing plate and extending in a front-rear direction;

a rotating plate positioned at a front side of the fixed plate and coupled to the rotating shaft; the rotary plate is detachably fixed on the back of the display main body, and can rotate around the axis of the rotary shaft relative to the fixed plate so as to drive the display main body to rotate; a plurality of arc-shaped grooves which are communicated front and back are formed in the rotating plate; the circle center of the arc-shaped groove is coincident with the rotation center of the rotating plate;

the rear end of the limiting piece is fixed on the fixed plate; the front end of the limiting piece is arranged in the arc-shaped groove in a penetrating way; the front end of the limiting piece extends forwards beyond the arc-shaped groove, and the rear end of the extending part is abutted to the front side of the rotating plate.

2. The display apparatus according to claim 1, wherein a front end of the stopper is formed with a protruding structure that exceeds the arc-shaped groove in a circumferential direction of the stopper so as to be capable of abutting against a front side of the rotating plate; the protruding structure can move in a direction approaching or separating from the fixed plate so as to adjust the pressure and damping force of the protruding structure to the rotating plate.

3. The display apparatus according to claim 2, wherein the stopper is a bolt including a rod portion extending in a straight line, and a head portion provided at one end of the rod portion; the head part protrudes outwards along the radial direction of the rod part to form the protruding structure; one end of the rod part, which is opposite to the head part, is in threaded connection with the fixing plate.

4. The display apparatus according to claim 2, wherein the rotating plate is provided with first and second friction plates on front and rear sides, respectively; the first friction plate and the second friction plate are sleeved on the periphery of the limiting piece, and the first friction plate is clamped between the fixed plate and the rotating plate; the second friction plate is clamped between the protruding structure and the front side surface of the rotating plate.

5. The display apparatus according to claim 1, wherein the front side of the rotating plate is formed with a convex rib; the convex ribs extend forwards beyond the front end of the limiting piece or are flush with the front end of the limiting piece; the front ends of the convex ribs are abutted against the rear side face of the display main body.

6. The display apparatus according to claim 1, wherein the hanger further comprises an extension bar detachably fixed on a peripheral edge of the rotating plate for fixing the display main body; the expansion strips are arranged at intervals around the rotation center of the rotating plate; the extension strip extends in a radial direction of the rotation axis.

7. The display device of claim 6, wherein a fixing hole is formed at an edge of the rotating plate, and the extension bar is detachably fixed to the fixing hole by a fastener.

8. The display device according to claim 7, wherein a clamping hole is formed in the rotating plate at a side of the fixing hole, which faces the rotating shaft, and a bending portion is formed at an end of the expansion bar, which faces the rotating shaft, and the bending portion is clamped in the clamping hole to position the expansion bar.

9. The display device according to claim 8, wherein the bending portion includes a first section bent and extended backward, and a second section bent and extended horizontally from one end of the first section; the first section is clamped in the clamping hole; the second section is abutted against the back or front side surface of the rotating plate.

10. The display device according to claim 8, further comprising a bracket fixedly connected to a rear surface of the fixing plate.
