Fuente: Wipo "BigData" The utility model provides a network monitoring device based on big data. Hanging plate, the front end surface of the hanging plate is fixedly connected with a display screen; the upper end face of the hanging plate is fixedly connected with a protruding block. The upper end face of the protruding block is slidably connected with a T-shaped sliding plate. The upper end of the T-shaped sliding plate is fixedly sleeved with a clamping plate. Two lug plates are fixedly connected to the upper end face of the clamping plate in a bilateral symmetry mode. The two ear plates are respectively positioned on the left side and the right side of the monitor; the left end and the right end of the monitor are rotationally connected with the lug plates through rotating rods; connecting blocks are fixedlyconnected to the left end surface and the right end surface of the convex block; an inserting rod vertically penetrates through the connecting block; according to the utility model, through the left and right movement of the T-shaped sliding plate and the rotation of the rotating rod, the position and the monitoring angle of the monitor can be adjusted, and the use effect is good.
