[0028] In order to improve the flatness of the display screen and improve the display effect, such as Figures 1 to 4 As shown, in this embodiment, the display screen installation device includes: a first connecting plate 10, a second connecting plate 20, a threaded column 30, a rotating disk 40, a rotation-stopping structure 50 and a connecting piece 60. The second connecting plate 20 is located on one side of the first connecting plate 10. The threaded column 30 is arranged on the first connecting plate 10. The rotating disk 40 is arranged between the first connecting plate 10 and the second connecting plate 20, and a connecting column 41 is arranged on the rotating disk 40, and a threaded hole matching with the threaded column 30 is arranged in the connecting column 41, and a limited position convex edge 42 is arranged on the connecting column 41. The rotation-stopping structure 50 is arranged between the second connecting plate 20 and the threaded column 30. The connecting piece 60 is arranged between the rotating disk 40 and the second connecting plate 20, and a first notch 61 is arranged on the connecting piece 60. The first notch 61 is clamped on the connecting column 41 so that the connecting piece 60 cooperates with the limit protrusion 42 to stop. The connecting piece 60 is connected to the second connecting plate 20 so that when the rotating disk 40 rotates and moves along the threaded column 30, the second connecting plate 20 is driven to move axially along the threaded column 30 through the connecting piece 60.

[0029] The technical solution of this embodiment is applied, the second connecting plate 20 is located on one side of the first connecting plate 10, the first connecting plate 10 is provided with a threaded column 30, a rotating disk 40 and a connecting piece 60 are provided between the first connecting plate 10 and the second connecting plate 20, the rotating disk 40 is provided with a connecting column 41 and a limiting convex edge 42 located on the connecting column 41, a threaded hole is provided inside the connecting column 41, and the threaded hole is screwed with the threaded column 30. A first notch 61 is provided on the connecting piece 60, the first notch 61 is stuck on the connecting column 41, and the limiting convex edge 42 can limit the position of the connecting piece 60 to prevent the connecting piece 60 from being separated from the connecting column 41. At the same time, the connecting piece 60 is connected to the second connecting plate 20. The rotating disk 40 can rotate along the threaded column 30 and move axially with the threaded column 30. Since the connecting piece 60 is connected to the rotating disk 40 and the second connecting plate 20, when the rotating disk 40 moves along the axis of the threaded column 30, the second connecting plate 20 also moves with the rotating disk 40. Furthermore, since the anti-rotation structure 50 is provided, the second connecting plate 20 can be effectively prevented from rotating together with the rotating disk 40. The above-mentioned arrangement enables the position of the second connecting plate 20 to be adjusted, thereby enabling the position of the display screen to be adjusted, thereby enabling the flatness of the display screen to be improved. Therefore, the technical solution of this embodiment effectively solves the problem of poor flatness of the display screen in the related art.

[0030] It should be noted that, in this embodiment, the first connecting plate 10 is connected to a wall or a mounting frame, and the second connecting plate 20 is connected to the display screen. At the same time, since the display screen can be arranged vertically, can be arranged tilted, and can also be arranged horizontally and facing the ground, it is pointed out in the above content that the first connecting plate is located on one side of the second connecting plate.

[0031] Consider the overall height of the display screen installation device to avoid the distance between the installation surface and the display screen being too large, which may cause unstable installation of the display screen. Figure 1 and Figure 5 As shown, in this embodiment, the connecting column 41 is arranged at the center of the rotating disk 40, and the rotating disk 40 is also provided with a recess 43 surrounding the connecting column 41, and the connecting piece 60 is installed in the recess 43. The arrangement of the recess 43 can effectively reduce the height of the overall structure to avoid the distance between the display screen and the installation surface being too large.

[0032] Of course, in an embodiment not shown in the figure, the surface of the rotating disk is a plane, so that the connecting column protrudes from the surface of the rotating disk, and the first section of the connecting piece contacts the surface of the rotating disk. The above arrangement can also realize the connection between the rotating disk and the second connecting plate.

[0033] In order to make the structural strength of the connecting piece better, Figure 1 and Figure 6As shown, in this embodiment, the connecting piece 60 includes a first section 62, a second section 63 and a third section 64, the first section 62 is located between the second section 63 and the third section 64, the first section 62 faces the rotating disk 40 and protrudes from the second section 63 and the third section 64, and the first notch 61 is located on the first section 62. The first section 62 is located between the second section 63 and the third section 64, and the first notch 61 is located on the first section 62, that is, the first notch 61 is located in the middle of the connecting piece 60, so that the structural strength of the connecting piece 60 is better and not easily damaged.

[0034] like Figure 1 and Figure 6 As shown, in this embodiment, fasteners 641 are provided on the second section 63 and the third section 64, and a connecting hole 21 corresponding to the fastener 641 is provided on the second connecting plate 20, and the connecting column 41 is plugged into the connecting hole 21. The plug-in connection method is simple and efficient, and can effectively connect the connecting piece 60 and the second connecting plate 20. There are two fasteners 641, which are respectively provided on the second section 63 and the third section 64. That is, the two fasteners 641 are respectively located on both sides of the first notch 61, and such a setting can make the connection effect between the connecting piece 60 and the second connecting plate 20 better and more stable.

[0035] In this embodiment, the connecting piece 60 is bent, and such a configuration can improve the structural strength of the connecting piece. Of course, in embodiments not shown in the figures, the connecting piece can also be a flat plate, which can also connect the rotating disk and the second connecting plate.

[0036] In order to prevent the second connecting plate from rotating with the rotating disk and affecting the stability of the display screen. Figure 1 and Figure 2 As shown, in this embodiment, the anti-rotation structure 50 includes an anti-rotation plane 51 disposed on the top of the threaded column 30 and an anti-rotation hole 52 located on the second connecting plate 20, and the anti-rotation hole 52 includes a limiting plane 521, and the anti-rotation plane 51 is in contact with the limiting plane 521. The anti-rotation plane 51 is inserted into the anti-rotation hole 52, and the anti-rotation plane 51 is in contact with the limiting plane 521 in the anti-rotation hole 52, so that the second connecting plate 20 can be limited to prevent the second connecting plate 20 from rotating and affecting the stability of the display screen.

[0037] Considering the lightweight design of the display mounting device, such as Figure 1 and Figure 2 As shown, in this embodiment, the second connecting plate 20 is cross-shaped. The cross-shaped shape can reduce the use of materials, thereby reducing the production cost of the product. It can also reduce the weight of the display screen mounting device, while ensuring the overall structural strength, and making the product as lightweight as possible.

[0038] In an embodiment not shown in the figure, the second connecting plate may be in a triangular shape or other shapes, as long as the shape can reduce the weight while ensuring the structural strength.

[0039] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the rotating disk 40 is provided with a weight-reducing hole 70 and a plurality of weight-reducing notches 80, and the weight-reducing hole 70 includes a plurality of first weight-reducing holes 71 and a plurality of second weight-reducing holes 72, the plurality of first weight-reducing holes 71 are arranged at intervals in the recess 43, the plurality of second weight-reducing holes 72 are located outside the recess 43, and the plurality of second weight-reducing holes 72 are arranged at intervals from the plurality of weight-reducing notches 80. The arrangement of the weight-reducing holes 70 and the weight-reducing notches 80 can effectively reduce the weight of the display screen installation device. The second weight-reducing holes 72 and the weight-reducing notches 80 are arranged at intervals, which reduces the weight of the product while ensuring the overall structural strength of the product, so that the display screen installation device can support and pull a large display screen.

[0040] like Figure 1 and Figure 3 As shown, in this embodiment, a fixing portion 11 is provided on the first connecting plate 10, and the fixing portion 11 includes a plurality of fixing portions, and a portion of the plurality of fixing portions 11 is a second notch 111; an anti-slip portion 44 is provided on the outer wall of the rotating disk 40. The provision of the fixing portion 11 can effectively enable the first connecting plate 10 to be fixed to the mounting surface, and the provision of the second notch 111 can reduce the mounting accuracy of the display screen mounting device, thereby making the installation of the display screen mounting device easier and improving the installation efficiency. The anti-slip portion 44 is an anti-slip tooth.

[0041] like Figure 1 and Figure 3 As shown, in this embodiment, the rotating disk 40 is a rounded rectangular shape, and the anti-skid portion 44 is located at the rounded corner of the rotating disk 40, and the rounded corner of the rotating disk 40 protrudes from the first connecting plate 10 and the second connecting plate 20. The anti-skid portion 44 is located at the rounded corner, and the rounded corner protrudes from the first connecting plate 10 and the second connecting plate 20. This makes it easy for the user to contact the anti-skid portion 44, and then easily rotate the rotating disk 40.

[0042] The display screen installation device of this embodiment can adjust its own height, and thus can adjust the flatness of the LED display screen. In addition, the display screen installation device of this embodiment is easy to install and adjust, and can adjust the flatness of multiple assemblies on one surface. At the same time, its structure is light in weight, which can save production costs.

[0043] The second connecting plate 20 is provided with a plurality of mounting holes, and the first connecting plate 10 is provided with a plurality of fixing holes.

[0044] Installation method: The first connecting plate 10 is fixed to the wall or steel structure by screws through the fixing holes, that is, the display screen installation device is fixed to the wall or steel structure. The display screen is fixed to the second connecting plate 20 by screws, and then the display screen is fixed to the wall or steel structure. The first connecting plate 10 is used as the main body, and the rotating disk 40 is screwed into the threaded column 30 by threads. The rotating disk 40 rotates around the threaded column 30 to adjust the height. The second connecting plate 20 is fixed to the rotating disk 40 by the connecting piece 60 and the fastener 641. Since the anti-rotation structure 50 is set, the second connecting plate 20 only has the degree of freedom in the up and down directions, and the rotating disk 40 can adjust the height of the second connecting plate 20. In use, multiple display screen installation devices are connected between the display screen and the wall at the same time. By adjusting the rotating disk 40, the display screen can be kept horizontal. In addition, multiple display screens are spliced ​​into a display screen, and by adjusting the rotating disk 40, it can be ensured that the multiple display screens are in the same plane.

[0045] According to another aspect of this embodiment, an LED display screen is provided, including a display screen installation device, wherein the display screen installation device is the above-mentioned display screen installation device. The above-mentioned display screen installation device can improve the flatness of the surface of the display screen, and therefore, the surface flatness of the LED display screen having the display screen installation device is better.

[0046] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.
