[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-3 As shown, the outdoor LED display device with good wind resistance performance is composed of a lower bar frame 1, an upper bar frame 2, a blocking bar frame 7 and a plurality of vertical bar LED display units 4;

[0019] The left sides of the lower bar frame 1 and the upper bar frame 2 are connected together by the left connecting frame 3. The top surface of the lower bar frame 1 is provided with a lower slide groove, and the bottom surface of the upper bar frame 2 is provided with an upper slide groove. The top of the vertical bar LED display unit 4 is rotatably installed with an upper moving block 8 through an upper rotating column 18, and the bottom of the vertical bar LED display unit 4 is rotatably installed with a lower moving block 9 through a lower rotating column. The lower moving block 9 is slidably installed in the lower slide groove, and the upper moving block 8 is slidably installed in the upper slide groove;

[0020] Both sides of the upper moving block 8 and the lower moving slider 9 are provided with spring grooves 12, and the spring grooves 12 on both sides are connected together through sliding holes, and a sliding column 11 is slidably inserted in the sliding hole, and a threaded column 14 is fixedly installed at one end of the sliding column 11, and the threaded column 14 is screwed together with the retaining bar frame 7, so as to drive the retaining bar frame 7 to move and press a plurality of vertical LED display units 4 to make them close together;

[0021] A gap spring 13 is provided in the spring groove 12, and the gap spring 13 is sleeved on the sliding column 11. When the blocking bar frame 7 moves to the right, the gap spring 13 spreads out a plurality of vertical LED display units 4, leaving gaps between them for smooth ventilation.

[0022] An angle adjustment cavity 19 is provided in the upper moving block 8, and an angle adjustment motor 16 is installed in the angle adjustment cavity 19. The angle adjustment motor 16 is connected to a small gear 15. The top of the upper rotating column 18 extends into the angle adjustment cavity 19 and is fixedly installed with a large gear 17. The large gear 17 is meshed and connected with the small gear 18 to facilitate angle adjustment and reduce the windward surface.

[0023] In this embodiment, a rod driving motor 10 is fixedly installed inside the upper slide groove and the lower slide groove. The rod driving motor 10 is connected to the slide column 11 to drive the rotation thereof.

[0024] In this embodiment, a wind force and direction sensor 6 is installed on the top of the upper bar frame 2 through a sensing frame, and the gap and angle between the plurality of vertical LED display units 4 are adjusted by sensing the direction and size of the wind.

[0025] In this embodiment, a distance detector 5 is embedded in the left connecting frame 3, and the detection direction of the distance detector 5 points to the blocking bar frame 7. When it is necessary to adjust several vertical LED display units 4 to make them in one plane, it can be known whether there is a deviation based on the detection distance of the distance detector 5, so as to make adjustments. Because of the deviation, it will flip a certain angle, thereby blocking the signal sent by the distance detector 5.

[0026] In this embodiment, the upper and lower ends of the blocking bar frame 7 are slidably installed in the upper sliding groove and the lower sliding groove respectively.

[0027] In the above structure, the wind force and direction are detected by the wind force and direction sensor 6. When the wind force is not strong, no adjustment is required. When the wind force is greater than the threshold, the start rod drives the motor 10, and the barrier frame 7 moves outward. Driven by the gap spring 13, several vertical LED display units 4 open gaps to allow ventilation. When it is necessary to further reduce the resistance, the angle adjustment motor 16 is started to rotate and adjust the angle to make it follow the wind, thereby achieving wind resistance.

[0028] Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
