Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a rotatable and closable LED display. Background Technology

[0002] LED Display Screen: A flat panel display composed of small LED module panels; such as the rotating and opening LED display screen with publication number CN219345931U, which includes a ground surface, a display screen control box on the ground surface, a connecting shaft on the control box, and a rotating plate rotatably connected to the control box via the connecting shaft, with the display screen mounted on the rotating plate. By symmetrically arranging fixing blocks on the control box and threaded stud structures with post caps on the fixing blocks, and symmetrically arranging positioning grooves on the rotating plate, the display screen can be rotated and folded for storage when not in use for a long time, and can be stably positioned by locking it in place. This improves the positioning stability of the touch-screen LED display screen used in outdoor shopping mall plazas after rotation and folding. Furthermore, by setting up a support column structure with a rain shelter on the ground, the entire touch-screen LED display screen can be protected, improving its sunshade and rain protection for outdoor shopping mall plazas.

[0003] However, existing LED displays cannot guarantee both portability and efficient splicing between multiple displays, which makes them inconvenient for temporary outdoor use. Therefore, we propose a rotatable and foldable LED display. Utility Model Content

[0014] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0015] Example: like Figures 1-4 As shown, a rotatable and closable LED display screen includes a base 9. A lead screw 1 is provided on the upper surface of the base 9. The outer side of the lead screw 1 is the display screen 3. A frame 5 is provided on the outer surface of the display screen 3. A fixed rod 6 is rotatably connected to one side of the frame 5, and the fixed rod 6 is rotatably connected to the base 9. A movable rod 4 is rotatably connected to the other side of the frame 5. A connecting arm 8 is provided on the inner side of the movable rod 4. A connecting block B11 is rotatably connected to one end of the connecting arm 8. The movable rod 4 passes through the connecting block B11. A connecting block A7 is rotatably connected to the other end of the connecting arm 8. A limiting rod 2 passes through the interior of the connecting block A7, and the limiting rod 2 is fixedly connected to the base 9. A movable ring 10 is fixedly connected to one end of the connecting block A7, and the lead screw 1 passes through the movable ring 10.

[0016] Specifically, top blocks 12 are provided on both sides of the bottom of the frame 5. A rocker arm 13 is provided on the front surface of the top block 12 and is rotatably connected to the frame 5. A spring 14 is fixedly connected to the bottom of the top block 12 and is fixedly connected to the frame 5. A reciprocating motor is provided inside the base 9 and the output shaft of the reciprocating motor is fixedly connected to the lead screw 1. The movable ring 10 is a hollow cylinder with threaded grooves on its inner wall. A circular hole is provided on the upper surface of the connecting block A7. Threaded grooves are provided at both ends of the outer surface of the lead screw 1 and the two threaded grooves are opposite to each other. A groove is provided on the front surface of the top block 12 and a protrusion is provided at one end of the rear surface of the rocker arm 13, and the protrusion is located inside the groove on the top block 12.

[0017] The workflow of this utility model is as follows: The lead screw 1 is driven to rotate. During the rotation of the lead screw 1, the two movable rings 10 on the lead screw 1 will move. Since the threaded grooves at both ends of the lead screw 1 are opposite, the movement directions of the two movable rings 10 will also be opposite. This will cause the swing direction of the connecting arm 8 to be opposite, ultimately causing the movable rod 4 to move. Due to the presence of the fixed rod 6, the display screen 3 will rotate to open or close during the displacement of the movable rod 4, thus realizing the use or storage of the display screen 3. When the display screen 3 needs to move in the opposite direction, the lead screw 1 is driven to rotate in the opposite direction. When the display screen 3 needs to be disassembled, it is pressed... When the display screen 3 is pressed, the spring 14 of the top block 12 is compressed, and at the same time, one end of the swing arm 13 moves on the top block 12, causing it to move to one side of the groove on the top block 12. At this time, the spring 14 rebounds, driving the top block 12 to rise, thereby fixing the display screen 3. Then the display screen 3 can be removed directly. When installing the display screen 3, simply insert the display screen 3 into the frame 5 and press the display screen 3 again. At this time, one end of the swing arm 13 will slide along the other side of the groove on the top block 12 and engage with the top of the groove on the top block 12, thus ensuring that the display screen 3 is completely inserted into the frame 5.

[0018] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
