Display device for economics

Abstract

The invention provides a display device for economics. The display device comprises a base, a display board, a controller and two sets of supports, wherein the two supports are symmetrically and fixedly erected at the top of the base, and the two ends of the display board are rotationally connected with the two supports respectively; a front face of the display board is a white board, long-strip-shaped through grooves are formed side by side, and a long-strip-shaped column structure is arranged in each through groove. each strip column structure comprises a first screw rod, a sliding block, an indicating rod and a nut; mounting blocks are fixedly arranged on the front faces of the sliding blocks, vertical baffles are fixedly arranged on one sides of the front faces of the display plates, and transverse baffles are fixedly arranged at the bottoms; a laser sensor is fixedly arranged at the bottom of the mounting block; a plurality of electronic boards are arranged on the front surface of the display board, and an electronic screen is erected above the display board; the range of vertical coordinates is input into the electronic screen, and the distance measured by each laser sensor is converted into a vertical coordinate value to be displayed on the electronic board. The device can rapidly display the statistical graph through the display board, and the statistical graph is convenient to adjust and replace.
