[0002] The LED module is composed of a kit, a base shell, a mask, etc. The full-color LED display is composed of individual LED modules, which is the full-color LED large screen we see now.

[0003] In the prior art, in order to facilitate the storage of the LED large screen, a deflection rack is generally used to change the angle of the large screen so that the display screen faces downward, thereby reducing the problem of dust falling on the screen surface. During the use of the screen, foreign objects (for example, light and easy-to-float streamers and colored ribbons generated by activities) are prone to appear on the upper side of the large screen. When the existing large screen is recycled, it is difficult to remove the foreign objects on the upper side of the large screen, and the foreign objects are easily clamped inside the deflection mechanism, which can easily cause the deflection mechanism to get stuck when used next time.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-Figure 4 The utility model discloses a full-color LED large-screen 5 display device, comprising an L-shaped frame 1L, a connecting shaft 2 is provided at the bottom of the L-shaped frame 1L, and a driving motor 3 fixedly connected to the L-shaped frame 1L is provided at one end of the connecting shaft 2, extension arms 4 are fixedly installed on both sides of the outer surface of the connecting shaft 2, an LED screen 5 is rotatably connected between the two extension arms 4, a guide mechanism 6 is commonly connected to the bottom ends of the two extension arms 4, an adjustment plate 7 is commonly connected to the bottom of one side of the extension arm 4, a guide groove 8 is opened inside the adjustment plate 7, an adjustment mechanism 9 is provided at the upper end of the adjustment plate 7, and a linkage slider 10 is provided inside the guide groove 8.

[0025] In this embodiment, when in use, the L-shaped frame 1L, the connecting shaft 2 and the driving motor 3 together form a deflection mechanism for adjusting the angle of the LED screen 5, so that the LED screen 5 can turn the direction of the display part, thereby preventing the surface of the display screen from adhering to dust when not in use, and the adjustment plate 7 is provided to install the adjustment mechanism 9, and the linkage slider 10 is pushed by the adjustment mechanism 9 to change the position of the linkage slider 10 inside the guide groove 8, so as to achieve the effect of adjusting the orientation angle of the LED screen 5, so that the LED screen 5 is directly facing the audience, and the guide mechanism 6, the adjustment plate 7 and the back side of the LED screen 5 together form a supporting bin, when the relative position of the LED screen 5 and the adjustment plate 7 changes, the space inside the supporting bin changes, and when the LED screen 5 moves, the air in the supporting bin moves, and at this time, the air enters or is discharged through the upper end of the supporting bin, thereby driving the air around the LED screen 5 to flow, so as to achieve the purpose of making it difficult for foreign matter to adhere to the surface of the LED screen 5;

[0026] Specifically, before the device is used, the deflection mechanism adjusts the LED screen 5 to a roughly desired position, and then pushes the linkage slider 10 through the adjustment mechanism 9, so that the linkage slider 10 pushes the LED screen 5 to expand outward, so that the bottom end of the LED screen 5 is away from the position of the adjustment plate 7. At this time, the space size inside the supporting bin becomes larger, and when the LED screen 5 is stored after use, the linkage slider 10 is moved through the adjustment mechanism 9. At this time, the distance between the LED screen 5 and the adjustment plate 7 is from far to near. At this time, the back side of the LED screen 5 will squeeze the air inside the supporting bin, so that the air inside the supporting bin is discharged from above, and then the flow of air makes it difficult for foreign matter to adhere to the top of the LED screen 5, thereby protecting the LED screen 5 from dust.

[0027] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the adjustment mechanism 9 includes a servo motor 91 , a transmission screw 92 is disposed at the bottom end of the servo motor 91 , and the transmission screw 92 is fixedly connected to the motor shaft of the servo motor 91 .

[0028] In this embodiment, the servo motor 91 is provided to drive the transmission screw 92 , and the transmission screw 92 is rotated to drive the linkage slider 10 to move.

[0029] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the linkage slider 10 includes a sliding block 101, which is inserted into the interior of the guide groove 8 and fits with the groove wall of the guide groove 8. A mounting hole 102 is opened at a position inside the sliding block 101 corresponding to the transmission screw 92, and the hole wall of the mounting hole 102 is provided with an internal thread that matches the transmission screw 92.

[0030] In this embodiment, when in use, the installation hole 102 and the internal thread are arranged so that the sliding block 101 is pushed to move during the rotation of the transmission screw 92 .

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a T-shaped guide rail 103 is provided on the back side of the LED screen 5, and a connecting slider 104 is sleeved in the middle of the T-shaped guide rail 103, and the end of the connecting slider 104 is rotatably connected to the sliding block 101 through a rotating shaft.

[0032] In this embodiment, the T-shaped guide rail 103 and the connecting slider 104 are provided to connect the LED screen 5 and the linkage slider 10 to each other, so that the linkage slider 10 can push the LED screen 5 to adjust the angle.

[0033] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the cross section of the adjustment plate 7 is in the shape of a right-angled trapezoid, and the straight direction of the guide groove 8 is the same as the inclined direction of the adjustment plate 7 .

[0034] In this embodiment, by the inclined setting of the guide groove 8, the distance between the linkage slider 10 and the guide groove 8 is changed during the movement of the linkage slider 10 inside the guide groove 8, so that the LED screen 5 can change its angle by following the movement of the linkage slider 10.

[0035] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the guide mechanism 6 includes an L-shaped connecting plate 61, and mounting plates 62 are provided on both sides of the L-shaped connecting plate 61, which are respectively fixedly connected to the bottom ends of the two extension arms 4, and the upper end of the L-shaped connecting plate 61 is fixedly connected to the bottom end of the adjustment plate 7.

[0036] In this embodiment, by providing the L-shaped connecting plate 61, the LED screen 5, the adjustment plate 7 and the L-shaped connecting plate 61 can together form a supporting bin with an opening at the upper end, so that when the angle between the LED screen 5 and the adjustment plate 7 changes, air can enter and exit the supporting bin through the upper end opening, thereby changing the air flow direction around the LED screen 5, thereby achieving the effect of preventing foreign objects from falling on the upper end of the LED screen 5.

[0037] In a further preferred embodiment of the present invention, Figure 1-4 As shown, an air bag 63 is arranged inside the L-shaped connecting plate 61 , and the top of the air bag 63 contacts the bottom end of the LED screen 5 .

[0038] In this embodiment, by providing the airbag 63, the gap between the bottom end of the LED screen 5 and the inner wall of the L-shaped connecting plate 61 is made close to each other, making it difficult for air to be discharged through the bottom side of the LED screen 5, thereby achieving the effect of increasing the air pressure when the air is discharged from the upper end of the supporting bin, and further increasing the air flow speed at the upper end of the LED screen 5, thereby achieving the effect of avoiding the retention of foreign matter.
