Detailed ways

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Example 1

Please refer to Figures 1-6, a new type of LED billboard, including a base 1, an LED light box 2 installed on the base 1, and a glass window 3 adapted to the LED light box 2, and a vertical wiper is arranged inside the light box Slat 4 and the driving mechanism that drives the reciprocating movement of the wiping strip 4, wherein, the side of the wiping strip 4 close to the glass window 3 is equipped with a cleaning cotton cloth, and the cleaning cotton cloth is in contact with the inner surface of the glass. A pair of screw rods 5 in 2 and a power unit that drives the two screw rods 5 to rotate forward or reverse synchronously, the screw sleeves on the screw rods 5 are provided with screw sleeves 6, and the wiping strips 4 are installed on the two screw sleeves 6 , by setting the wiping slat 4, the screw 5, the screw sleeve 6 and the power unit, the power unit drives the screw 5 to rotate forward and reverse, and can drive the wiping slat 4 to reciprocate in the LED light box 2 to cooperate with the wiping slat 4 The cleaning cotton cloth installed on the side can clean the water mist and dust on the inner surface of the glass window 3, effectively avoid the adverse effects of water mist and dust on the inner surface of the glass window 3 on the publicity effect of the LED billboard, and improve the performance of the LED billboard. applicability.

Preferably, the power unit includes a rotating shaft 7, a worm 8, a worm wheel 9, a winding wheel 10, a pull cord 11, a support plate 12 and a return coil spring 13, and the rotating shaft 7 is vertically rotated through the support plate 12 and is arranged on the LED light box 2, the rotating shaft 7 is located on the rod body in the support disc 12 and is wound with a return coil spring 13, and the rotating shaft 7 is fixedly equipped with a winding wheel 10, and the worm wheel 9 and the worm 8 are provided with two, two worms 8 Symmetrically installed at both ends of the rotating shaft 7, two worm gears 9 are coaxially fixedly installed on the two screw rods 5 one by one, and meshed with the worm screw 8, one end of the stay rope 11 is wound on the winding wheel 10, and the other One end runs through the side wall of the LED light box 2 and is equipped with a pull ring 14. The setting of the power unit can not only drive the wiping strip 4 to reciprocate in the LED light box 2, but also drive the wiping strip 4 to move to the end of the LED light box 2. The side position avoids the phenomenon that the wiping slat 4 will block the LED billboard. In addition, the power unit does not need to be equipped with a control system such as a controller, and has the advantages of simple structure and low cost.

Wherein, two support discs 12 are provided, and the two support discs 12 are symmetrically arranged on both sides of the reel 10 .

In addition, after using the cleaning cotton cloth on the wiping slat 4 for a long time, more dust and dirty water will be absorbed on the cleaning cotton cloth.
