Detailed Description
The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Terms used herein, including technical and scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art, provided that the terms are not defined differently. It is to be understood that terms defined in commonly used dictionaries have meanings that are consistent with the meaning of the terms in the prior art.
See fig. 1-3
A blue light prevention intelligent blackboard comprises a main screen 1 and a bracket; the main screen 1 is provided with a blue light preventing film, and the main screen 1 is provided with a frame 2; a transverse frame 3 is arranged in the bracket; a rotating mechanism is arranged on the transverse frame 3; the bottom of the frame 2 is provided with a bottom plate 4; the rotating mechanism is connected with the bottom plate 4; the bottom plate 4 is provided with a swinging mechanism; the swinging mechanism is connected with the main screen 1; the two sides of the main screen 1 are rotationally connected with the frame 2.
Further, the rotating mechanism comprises a first driving motor 5 arranged on the transverse frame 3; the bottom of the bottom plate 4 is provided with a connecting seat 6; the first driving motor 5 is connected with a speed reducer; the rotating mechanism also comprises a gear column 7 arranged at the bottom 6 of the connecting seat.
