[0026] Example: A portable foldable LED display screen, such as Figure 1 , Figure 2 and Figure 4 As shown, the device includes a mounting frame 1, a mounting block 2, a connecting block 3, a display screen body 4, a first torsion spring 5, a first protrusion 6, an electric push rod 7, a push block 8, and a protective structure 9. Wheels are mounted on the bottom of the mounting frame 1 for easy movement of the device. The mounting block 2 is slidably connected to the top of the mounting frame 1. Connecting blocks 3 are rotatably connected to the left and right sides of the front of the mounting block 2 via shafts. The display screen body 4 is fixedly connected to the outer side of the connecting block 3. A first torsion spring 5 connects the connecting block 3 and the mounting block 2. Figure 2When in the state, the first torsion spring 5 is in a deformed state. The top of the shaft used for rotating connection of the adapter block 3 is provided with a first protrusion 6. An electric push rod 7 is provided in the front-rear direction of the top of the mounting block 2. A push block 8 is connected to the telescopic rod on the front side of the electric push rod 7. The push block 8 is concave and is slidably connected to the top of the mounting block 2. The left and right sides of the push block 8 are in contact with the side of the first protrusion 6. Under the action of the push block 8, the protruding end of the first protrusion 6 faces the front side, causing the first torsion spring 5 to deform. A protective structure 9 is provided on the outer surface of the mounting block 2, which covers the structure on the outer surface of the mounting block 2.

[0027] like Figure 4 As shown, the protective structure 9 includes a protective frame 91, a motor 92, a lead screw 93, and a push-pull rod 94. The protective frame 91 is slidably connected to the outer surface of the mounting block 2. The motor 92 is installed at the top inside the protective frame 91. The lead screw 93 is connected to the output shaft at the bottom of the motor 92. The bottom end of the lead screw 93 is threadedly connected to the protective frame 91. The lead screw 93 is rotatably connected to the bottom of the mounting block 2. A push-pull rod 94 is provided on the upper rear side of the protective frame 91. By controlling the rotation of the motor 92, the lead screw 93 is driven to rotate, which can drive the protective frame 91 and its components to move vertically.

[0028] like Figure 3 As shown, it also includes an electric track 10, a telescopic frame 11, a connecting block 12, and a second torsion spring 13. The electric track 10 is fixedly connected to the bottom of the mounting frame 1. The telescopic frame 11 is connected to the slider of the electric track 10. The connecting block 12 is rotatably mounted on the upper surface of the telescopic frame 11. The connecting block 12 is fixedly connected to the bottom of the mounting block 2. The second torsion spring 13 is connected between the connecting block 12 and the telescopic frame 11. By controlling the electric track 10 to drive the telescopic frame 11 to close or open, the mounting block 2 and its components can be moved vertically.

[0029] like Figure 6 As shown, it also includes a fixing structure 14. The fixing structure 14 is provided on the left and right sides of the mounting frame 1. The fixing structure 14 includes a rotating plate 141, a suction cup 142, a telescopic rod 144, a third torsion spring 145, and a second protrusion 146. The lower part of the left and right sides of the mounting frame 1 is provided with a rotating plate 141 rotatably mounted on a shaft. The rotating plate 141 is connected to the mounting frame 1 by a third torsion spring 145. The rotating plate 141 is symmetrically provided with suction cups 142 at the front and back. The rotating plate 141 below the suction cup 142 is provided with an insertion hole 143. The upper part of the left and right sides of the mounting frame 1 is rotatably mounted with a telescopic rod 144. The bottom end of the telescopic rod 144 is rotatably connected to the rotating plate 141. The front and back ends of the shaft rotatably connecting the rotating plate 141 are provided with a second protrusion 146.

[0030] like Figure 6As shown, it also includes an automatic opening structure 15. The automatic opening structure 15 is provided on both the front and rear sides of the mounting frame 1. The automatic opening structure 15 includes a top rod 151, a guide rod 152, a concave stop rod 153 and a first spring 154. The top rod 151 is provided on both the front and rear sides of the mounting block 2, and the guide rod 152 is provided on both the front and rear sides of the mounting frame 1. The concave stop rod 153 is slidably connected to the guide rod 152 on the same side. The first spring 154 is connected between the concave stop rod 153 and the guide rod 152. The top of the concave stop rod 153 contacts the bottom of the top rod 151. The left and right sides of the concave stop rod 153 contact the sides of the second protrusion 146. Under the action of the concave stop rod 153, the protruding end of the second protrusion 146 faces downward, causing the third torsion spring 145 to deform.

[0031] like Figure 7 and Figure 8 As shown, it also includes a cleaning structure 16. The lower left and right sides of the protective frame 91 are provided with cleaning structures 16. The cleaning structure 16 includes a connecting plate 161, a wiping block 162 and a second spring 163. The lower left and right sides of the protective frame 91 are provided with connecting plates 161. Wiping blocks 162 are slidably arranged on the front and rear parts of the connecting plates 161. The second spring 163 is connected between the wiping block 162 and the connecting plate 161 to provide a buffer space for the wiping block 162. The inner side of the wiping block 162 contacts the outer surface of the display body 4 and is used to clean the surface of the display body 4.

[0032] In use: First, control the motor 92 to rotate, which in turn drives the lead screw 93 to rotate, thereby moving the protective frame 91 upward. During the upward movement of the protective frame 91, the wiping block 162 moves upward to wipe the side of the display screen body 4. After the protective frame 91 moves above the display screen body 4, control the motor 92 to stop working. At this time, control the electric push rod 7 to shorten, driving the push block 8 to move backward. After the push block 8 leaves the first protrusion 6, the first torsion spring 5 resets, driving the adapter block 3 and the display screen body 4 to rotate forward and merge together. The left and right sides of the display screen body 4 are spliced ​​together. After the display screen body 4 is spliced, control the electric track 10 to drive the telescopic frame 11 to close, causing the mounting block 2 and its upper device to move upward, thereby driving the display screen body 4 to move upward to the required height. Control the electric track 10 to stop working, and when the mounting block 2 moves upward, it drives the top rod 151 to move upward. When the first spring 154 resets, the concave stop bar 153 moves upward, moving away from the second protrusion 146. Under the reset action of the third torsion spring 145, it drives the rotating plate 141 to rotate downward and contact the ground, and the suction cup 142 adheres to the ground. At this time, the device can also be fixed to the ground by inserting a rod through the insertion hole 143. After the device is used, first pull out the rod, then rotate the rotating plate 141 upward, so that the rotating plate 141 fits against the outer surface of the mounting frame 1. The third torsion spring 145 deforms, and then the telescopic frame 11 is reset by the electric rail 10, so that the mounting block 2 and its upper device move downward and reset. The push rod 151 pushes the concave stop bar 153 downward and resets, pressing against the second protrusion 146. The first spring 154 is compressed, and then the electric push rod 7 is controlled to extend and reset, driving the push block 8 to move forward. The push block 8 pushes the first protrusion 6 to rotate to Figure 2 In this state, the first protrusion 6 drives the adapter block 3 and the display screen body 4 to return to their original state. Figure 2 The device is then reset via motor 92, which drives the protective frame 91 and its devices to return to their original state. Subsequently, the device is moved via push-pull rod 94.
