Referring to FIG. 6 , the fastening portion 2072 of the friction plate 207 cooperates with the fixing hole 2023 of the first support body 202 , so that the friction plate 207 is fastened to one side of the first support body 202 . The side surface is opposite to the side surface on which the finite protrusion 2025 is disposed. At this time, the through hole 2071 is opposite to the through hole 2021 of the first support body 202. The latching portion 2042 of the elastic spacer 204 is snapped into the fixing hole 2024 of the first supporting body 202, so that the elastic spacer 204 is fixed to the other side of the first supporting body 202. The shaft hole 2041 of the elastic spacer 204 is opposite to the through hole 2021 of the first support body 202. The latching portion 2054 of the mating 205 is snapped into the positioning recess 2033 of the second support body 203. The pivot 201 is sequentially inserted into one of the flat washers 206, the friction plate 207, the first support body 202, the elastic spacer 204, the mating spacer 205, the second support body 203, and another flat washer 206, and finally with the locking member 208. The threaded holes (not shown) cooperate to prevent the above components from coming apart from each other. At this time, the first support body 202 is disposed opposite to the second support body 203, the pivot shaft 201 is disposed in the first support body 202 and the second support body 203, and the pivot 201 can be rotated in the through hole 2021, and the mat is mated. The sheet 205 and the flat washer 206 are non-rotatable relative to the pivot 201, and the limiting protrusions 2025 of the first support body 202 are received in the arcuate limiting slots 2032 of the second support body 203.

The locking member 207 is tightened, which will press the elastic spacer 204 and elastically deform the elastic spacer 204. In the initial state, the protrusion 2042 of the elastic spacer 204 is snapped into the through hole 2053 of the mating spacer 205, and the limiting protrusion 2025 abuts against one end of the arc limiting slot 2032. Finally, the display screen 400 is fixed to the second support body 203.

The display 400 is rotated in a plane relative to the first support body 202. At this time, the limiting protrusion 2025 slides in the arc limiting slot 2032, and the protrusion 2042 of the elastic spacer 204 slides out of the matching spacer. The through hole 2053 of the 205 is then slid inside the sliding groove 2052 of the mating spacer 205. When the display screen 400 is rotated to a certain angle, the protrusion 2042 of the elastic spacer 204 slides out of the sliding slot 2052 and then slides a certain distance on the plane of the mating spacer 205, and then snaps into the through hole 2053 of the mating spacer 205. , thereby generating a certain hand and simultaneously achieving positioning at the corresponding position.

After the protrusion 2042 slides out of the through hole 2053 again, the deformation is restored by the mating spacer 205.

When the display 400 is rotated to a certain angle, the limiting protrusion 2025 abuts against the arc limiting slot 2032 At the other end, thereby restricting further rotation of the display screen 400. In this embodiment, the display screen 400 can be rotated by about 90 degrees. At this time, the display screen 400 is changed from the horizontal position to the vertical position, thereby realizing the change between the two states of the display screen 400 placed in the lateral direction and in the longitudinal direction. Because the aspect ratio of the flat panel display is the same as the aspect ratio of the screen, it is better for the image of the object with a larger vertical size, and it looks more dynamic and realistic. Of course, the rotation angle can be set according to actual needs.

Referring to FIG. 7, a hinge structure 500 according to a second embodiment of the present invention is similar to the hinge structure 200 of the first embodiment, except that the mating spacer 505 of the hinge structure 500 is fixed to the first support body 502, and is elastic. The spacer 504 is fixed to the second support 503.

It can be understood that the locking member 208 can also be a rivet piece, and the end of the pivot 201 away from the limiting flange 201 can be directly riveted with the locking member 208 without providing a threaded portion.

The hinge connection structure 200 can be used to implement the tilt adjustment of the display screen 400. In addition, the limiting protrusion 2025 can be formed on the second supporting body 203, and the corresponding curved limiting groove 2032 is opened in the first supporting body 202.
