The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a rotatable LED display screen, such as Figure 1-5 As shown, it includes a base 1, a support platform 2 is fixedly connected to the top center position of the base 1 by bolts, a slide groove 3 is opened at the top center position of the support platform 2, a slider 4 is slidably connected inside the slide groove 3, a first rotating column 5 is rotatably connected to the top of the slider 4, an LED display screen frame 6 is integrally formed at the top of the first rotating column 5, an LED display screen 7 is embedded and fixed on the inner side wall of the LED display screen frame 6, a second rotating column 8 is integrally formed at the bottom of the LED display screen frame 6 near the side position of the first rotating column 5, a fixing block 9 is rotatably connected to the bottom end of the second rotating column 8, a first threaded hole 10 and a second fastening nut 14 are opened at the bottom of the support platform 2, the first threaded hole 10 is located on one side of the second fastening nut 14, and the first threaded hole 10 is screwed with the first fastening nut 11 through a thread, and the second fastening nut 14 is screwed with the second fastening nut 14 through a thread, a first limiting hole 12 is opened at the bottom center position of the slider 4, and a second limiting hole 15 is opened at the bottom center position of the fixing block 9.

[0023] It should be noted that, since most of the existing rotatable LED display screens use the middle position of the display screen as the rotation axis, the side of the display screen performs axial rotation along the axis. Although the purpose of rotation can be achieved, the rotation radius of the display screen will be large. When the display screen is fixed in a narrow space on one side, the rotation angle of the display screen is small or even cannot be rotated. In this embodiment, the LED display screen frame 6 performs axial rotation with the first rotating column 5 as the axis, so that one side of the LED display screen 7 can be axially rotated with a small radius, reducing the space required for the rotation of the LED display screen 7, and thus facilitating the rotation at a narrow space on one side of the LED display screen 7, thereby facilitating the temporary lateral angle display of the LED display screen 7, thereby improving the adaptability of the LED display screen 7 when used, and by sliding the slider 4 on the support platform 2, the LED display screen 7 can be rotated 180 degrees and then displayed in the reverse direction, further improving the rotation range of the LED display screen 7.

[0024] Specifically, in this embodiment, the scheme mainly includes a slider 4 and a fixing block 9. When in use, the base 1 is fixedly installed at the position where the LED display screen 7 is required to be installed. When the LED display screen 7 needs to be rotated to a certain angle for display, the second fastening nut 14 is rotated to screw the second fastening nut 14 out of the second threaded hole 13, and one end of the second fastening nut 14 leaves the second limiting hole 15. After the fixing block 9 loses its limit, the first rotating column 5 is rotated on the slider 4, and one hand holds one side end of the LED display screen frame 6 and rotates it around the first rotating column 5 as the axis. The LED display screen frame 6 is rotated. The display screen frame 6 rotates, thereby realizing the rotation of the LED display screen 7, which is convenient for temporary lateral angle display. When the LED display screen 7 needs to be flipped 180 degrees for display, the slider 4 slides in the slide groove 3 to move the slider 4 to an inner end of the slide groove 3. At this time, after the LED display screen 7 is rotated 180 degrees with the first rotating column 5, the fixed block 9 on the LED display screen 7 is moved to the top of the support platform 2, and the slider 4 and the fixed block 9 are respectively locked by the first fastening nut 11 and the second fastening nut 14 to realize the fixation of the position of the LED display screen frame 6 after flipping.

[0025] In a further preferred embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the cross section of the base 1 is a "convex" shaped structure, and a mounting hole is provided on the top of the base 1, and the cross sections of the slide groove 3 and the slider 4 are both "T" shaped structures.

[0026] In this embodiment, the "convex"-shaped base 1 can provide support for the support platform 2 and reserve a position for installation and fixing. The "T"-shaped structure slide groove 3 and slider 4 can ensure the stability of the sliding of the slider 4 in the slide groove 3 and prevent the slider 4 from falling off the slide groove 3.

[0027] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, one end of the first fastening nut 11 can be embedded in the first limiting hole 12, and one end of the second fastening nut 14 can be embedded in the second limiting hole 15. The length of the first fastening nut 11 is shorter than that of the second fastening nut 14.

[0028] In this embodiment, by inserting one end of the first fastening nut 11 into the first limiting hole 12 and one end into the second limiting hole 15, the position fixation of the slider 4 and the fixing block 9 can be achieved, thereby ensuring that the LED display screen frame 6 is stably fixed on the support platform 2 and preventing the LED display screen frame 6 from sliding and shaking on the support platform 2.

[0029] In a further preferred embodiment of the present invention, Figure 1 As shown, the top ends of the first rotating column 5 and the second rotating column 8 are located at the same horizontal plane.

[0030] In this embodiment, the levelness of the LED display screen frame 6 can be ensured.
