Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically a rotating and opening LED display. Background Technology

[0002] An LED display screen is a display device that uses semiconductor light-emitting diodes (LEDs) as the basic light-emitting unit. It displays various information, including text, graphics, images, animations, and videos, by controlling the on / off state or brightness of the LEDs.

[0003] Patent CN222351932U discloses a rotating and opening LED display screen, which includes a display screen body. A rotating and opening mechanism for rotating and opening the display screen body is provided on one side of the display screen body. The rotating and opening mechanism is provided with a limiting component to improve the stability of the display screen body when rotating. By providing the rotating and opening mechanism, the device can also control the orientation angle of the display screen body to facilitate the viewing of the audience. By providing the limiting component, the stability of the rotating and opening mechanism when rotating is improved and the shaking of the rotating and opening mechanism is prevented.

[0004] However, this device displays content through the display screen itself, but only two display screens on the same plane are set up to display content. This means that even if the display range of the display screen is adjusted by using a turntable, there will still be blind spots, which reduces the display effect of the display screen. To address this, a rotating and opening LED display screen is proposed to solve the problem of large blind spots in existing LED display screens that affect the display effect. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figure 1-4A rotating and opening LED display screen includes a mounting plate 1. One end of the mounting plate 1 is symmetrically and fixedly connected to a fixed base 2. Two adjusting plates 3 are symmetrically arranged between the fixed bases 2. One end of the mounting plate 1 is provided with a first display screen 4. The end of the adjusting plate 3 facing the mounting plate 1 is provided with a second display screen 5. The mounting plate 1 has slots 6 on both sides. The adjusting plates 3 are rotatably arranged between the fixed bases 2 through a limiting shaft 7. The bottom of the fixed base 2 is provided with a limiting plate 8. The bottom of the limiting plate 8 is penetrated and screwed with a limiting bolt 9. The bottom of the mounting plate 1 is symmetrically and fixedly connected with a support column 10. The bottom of the support column 10 is fixedly connected with a base frame 11. The bottom of the mounting plate 1 is provided with a stabilizing mechanism 12. The bottom of the bottom fixed base 2 is provided with a limiting mechanism 13.

[0024] Furthermore, the limiting pivot 7 passes through the fixed base 2 and is fixedly connected to the limiting plate 8, the limiting bolt 9 passes through the limiting plate 8 and contacts the bottom fixed base 2, and the bottom surface of the bottom fixed base 2 is rough.

[0025] Furthermore, the stabilizing mechanism 12 includes stabilizing plates 121 symmetrically arranged at the bottom of the mounting plate 1. The stabilizing plates 121 are rotatably arranged at the bottom of the mounting plate 1 via rotating posts 122. A stud 123 is threaded through and screwed onto the top of the stabilizing plate 121. When the adjusting plate 3 is rotated to a suitable position for content display on the second display screen 5, the stabilizing plate 121 can be rotated to a suitable position under the action of rotating posts 122. Then, the stud 123 can be moved upward into the stabilizing support groove 125 at the bottom of the adjusting plate 3 by the knob 124, thereby supporting the adjusted plate 3 and improving the stability of the rotating and opening LED display screen when it is opened for display.

[0026] Furthermore, a knob 124 is fixedly connected to the bottom of the stud 123, and a stabilizing support groove 125 is provided at the bottom of the adjusting plate 3.

[0027] Furthermore, the limiting mechanism 13 includes a limiting seat 131 fixedly connected to the bottom of the bottom fixed seat 2. A lifting seat 132 is slidably provided in the inner cavity of the limiting seat 131. The top of the limiting seat 131 is symmetrically and fixedly connected to a limiting post 133. A limiting hole 134 is opened at the bottom of the adjusting plate 3. The limiting post 133 passes through the fixed seat 2 and the two are threadedly connected.

[0028] Furthermore, when the adjusting plate 3 is in its initial position, the positions of the limiting post 133 and the limiting hole 134 correspond. The top of the lifting seat 132 is threaded through and screwed with a limiting screw 135. The limiting screw 135 passes through the limiting seat 131 and the intersection is rotatably connected by a bearing. The bottom of the limiting screw 135 is fixedly connected with a limiting knob 136. When it is necessary to move and transport this LED display screen, the adjusting plate 3 is reset to cover the first display screen 4 at one end of the mounting plate 1. At this time, the second display screen 5 is wrapped and protected. Then, the limiting knob 136, in conjunction with the bearing, drives the limiting screw 135 to rotate, thereby driving the lifting seat 132 in the limiting seat 131, together with the limiting post 133, to insert into the limiting hole 134 at the bottom of the adjusting plate 3, thereby fixing the adjusting plate 3 to one side of the mounting plate 1, improving the safety of this rotating and opening LED display screen during movement and transportation.

[0029] Working principle: When using this rotating and opening LED display screen, the mounting plate 1 is supported in the desired display position by the base frame 11 and the support column 10. Under the action of the limiting shaft 7, the two adjusting plates 3 between the fixed seats 2 are rotated to the appropriate display position. Then, the limiting bolts 9 on the limiting plate 8 are tightened to fix the position of the limiting plate 8 together with the limiting shaft 7. With the first display screen 4 and the second display screen 5, a large range of content can be displayed, which solves the problem of large blind spots in the display of existing LED displays that affect the display effect. When it is necessary to move and transport this LED display screen, the adjusting plate 3 is reset to cover the first display screen 4 at one end of the mounting plate 1. At this time, the second display screen 5 is wrapped and protected. Then, the limiting knob 136 drives the limiting screw 135 to rotate through the bearing, which in turn drives the lifting seat 132 in the limiting seat 131 together with the limiting column 133 to insert into the limiting hole 134 at the bottom of the adjusting plate 3, thereby fixing the adjusting plate 3 to one side of the mounting plate 1, improving the safety of this rotating and opening LED display screen during movement and transportation.
