In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

Referring to fig. 1 to fig. 6, the present embodiment provides a hinge structure, which includes a mounting base 10, four elastic members 20, two hinge shafts 30, four pressing members 40, and four movable members 50.

Wherein, two rotation holes 1011 have been seted up on the mount pad 10, and one of them pivot 30 wears to establish in one of them rotation hole 1011, and another pivot 30 wears to establish in another rotation hole 1011 for two pivot 30 can both rotate for mount pad 10. Secondly, a first limiting hole 1012 is further disposed in the mounting seat 10, and a circle of blocking part 1013 is convexly disposed on the hole wall of the first limiting hole 1012, so that a second limiting hole 1014 with a smaller aperture size is formed in the first limiting hole 1012.

Each rotating shaft 30 is sleeved with two pressing pieces 40, the two pressing pieces 40 are located on different sides of the rotating hole 1011, and the outer wall of each pressing piece 40 has a convex surface 401, in other words, each pressing piece 40 is in a cam shape design. In addition, the outer wall of the rotating shaft 30 is further sleeved with a single-hook washer 60, a flat washer 70, a bowl-shaped washer 80, a sleeve 90, a nut 100 and the like, so as to fix the pressing member 40 at a desired position on the rotating shaft 30, limit the position of the rotating shaft 30 relative to the mounting seat 10 in the axial direction, and prevent the rotating shaft 30 from axially disengaging from the rotating hole 1011 along the self-axis direction, thereby ensuring that the rotating shaft 30 can reliably rotate relative to the mounting seat 10.

Wherein, four elastic components 20 are all correspondingly placed one by one in each rotation hole 1011, and the bottom of elastic component 20 butts on the inner wall of mount pad 10, rotates the effect that hole 1011 played restriction elastic component 20, makes elastic component 20 only can make concertina movement in rotating hole 1011. In addition, the center line of the expansion and contraction deformation of each elastic member 20 is opposite to the outer wall of one pressing member 40. In this embodiment, the elastic member 20 is preferably a compression spring.

Wherein, four moving parts 50 are correspondingly placed in each rotating hole 1011 one by one. Specifically, the movable element 50 includes a guide portion 501 and a protrusion 502 connected to each other, the guide portion 501 is inserted into the first limiting hole 1012 and abuts against the top of the elastic element 20, the shape of the guide portion 501 matches with the shape of the first limiting hole 1012, so that the guide portion 501 can slide along the depth direction of the first limiting hole 1012, and the blocking portion 1013 is disposed on a side of the guide portion 501 opposite to the elastic element 20, so that the guide portion 501 can abut against the blocking portion 1013 under the elastic force of the elastic element 20, and thus, it can be seen that the blocking portion 1013 blocks the guide portion 501, and the movable element 50 is prevented from being separated from the first limiting hole 1012. The shape of the protruding portion 502 matches the shape of the second stopper hole 1014, so that the protruding portion 502 can slide along the depth direction of the second stopper hole 1014, and thus, by providing the second stopper hole 1014, the guide area between the movable member 50 and the mounting base 10 can be increased, and the movable member 50 can be ensured to slide smoothly relative to the mounting base 10. In addition, the end of the projection 502 facing away from the elastic member 20 is provided with a concave surface 5021, and the concave surface 5021 is used for being matched and abutted with the convex surface 401.

Further, when the rotating shaft 30 rotates relative to the mounting base 10, the pressing member 40 rotates synchronously with the rotating shaft 30, and the moving member 50 can abut against the outer wall of the pressing member 40 under the elastic acting force of the elastic member 20, so that the pressing member 40 can drive the elastic member 20 to compress, and at this time, the elastic acting force indirectly transmitted to the pressing member 40 by each elastic member 20 through the moving member 50 is the compensation force in the radial direction of the rotating shaft 30. In addition, because the pressing member 40 and the movable member 50 are mutually matched and abutted through the convex surface 401 and the concave surface 5021, more abutting areas are formed between the pressing member 40 and the movable member 50, and the sliding friction force between the pressing member 40 and the movable member 50 can be reduced, so that the rotating shaft structure is more stable and reliable in use.

In other embodiments, the concave surface 5021 can be disposed on the pressing member 40, and correspondingly, the convex surface 401 can also be disposed on the movable member 50.

Furthermore, if the torque compensated by the rotating shaft 30 is not enough to be actually needed, the rotating shaft 30 can be rotated continuously to make the compression amount of the elastic element 20 larger, and the compression can be achieved by using several sets of pressing elements 40 on the rotating shaft 30, which of course requires the elastic element 20 and the movable element 50 to be disposed at corresponding positions on the mounting base 10.

In addition, without rotating the rotating shaft 30, the compression amount of the elastic member 20 may be changed by changing the position where the elastic member 20 abuts in the mounting seat 10, thereby realizing the function of adjusting the force of the rotating shaft 30. Specifically, the method comprises the following steps: the mounting seat 10 of the embodiment specifically includes a seat body 101, an adjusting plate 102 and a driving element 103, wherein the rotation hole 1011, the first limit hole 1012 and the second limit hole 1014 are all disposed on the seat body 101, a through hole 1021 is formed in the adjusting plate 102, the driving element 103 is a screw, an internal thread matching with the driving element 103 is formed at the bottom of the seat body 101, the driving element 103 passes through the through hole 1021 and is screwed on the internal thread of the seat body 101, a butting portion 1022 is formed on the adjusting plate 102, both the two elastic members 20 are butted against the butting portion 1022, when the driving element 103 is screwed, the adjusting plate 102 can move in the telescopic direction of the elastic members 20 relative to the seat body 101, so as to adjust the compression amount of the elastic members 20, thereby achieving the function of adjusting the compensation force of the rotating shaft 30, and having the advantage of convenient adjustment.

The embodiment further provides a display support, which uses the rotating shaft structure of the technical scheme, so that the space occupied by the rotating shaft structure inside the display support in the radial direction of the rotating shaft 30 is smaller, and the design requirement of the compact space inside the display support is met.

The foregoing is considered as illustrative only of the preferred embodiments of the invention, and not as limiting the scope of the invention in any way. Any modifications, equivalents, and improvements made within the spirit and principles of the invention and other embodiments of the invention that may occur to persons skilled in the art without the use of inventive faculty are intended to be included within the scope of the invention as defined in the claims.
