Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
Referring to fig. 1-3, a stage display screen with surface dust removal function includes a frame 1 and a display screen main body 2 installed in the frame 1, and further includes a dust removal mechanism, the dust removal mechanism includes a movable frame 3 movably disposed on a side surface of the frame 1 and a driving component for driving the movable frame 3 to reciprocate up and down, a roller 4 is rotatably installed in the movable frame 3, cleaning cotton is installed outside the roller 4, the dust removal mechanism further includes a power unit for providing power for rotation of the roller 4, the driving component in the dust removal mechanism drives the movable frame 3 to reciprocate up and down along with the roller 4 in the movable frame 3, cleaning cotton on the roller 4 can clean dust on the display screen, thereby ensuring attractiveness of the display screen, and setting of the power unit, and in the process of up and down movement of the roller 4, a speed difference is formed between a rotation speed and a down movement speed of the roller 4, thereby forming a relative friction effect between the roller 4 and the display screen main body 2, and further improving cleaning effect.
The power unit comprises a pair of straight racks 5 symmetrically arranged on the side face of the frame 1 and a gear 6 meshed with the straight racks 5, wherein the gear 6 is rotatably arranged in the movable frame 3 and is fixedly connected with the roller 4 in a coaxial manner, and the power unit does not need to be additionally provided with a driving element to drive the roller 4 to rotate, so that the roller has the advantages of simple structure and low cost.
