Abstract

The invention provides a chart hanging device for ideological and political education. The device comprises a base, a support rod, a main panel, chart hanging plates, a remote control signal transmitter, a remote control signal receiver, a magnet device, electromagnets, a circuit board and a power supply, wherein number keys and upward and downward keys are arranged on a panel of the remote control signal transmitter; a to-be-selected page number is input by pressing the number keys, the remote control signal transmitter transmits a page turning signal and a page signal to the remote control signal receiver, a CPU controller controls the circuit board according to the signals received by the remote control signal receiver to determine that the electromagnet on the chart hanging plate on the corresponding page is internally conducted and produces force opposite to that of the magnet device on the main panel, meanwhile, the electromagnet on the back of the previous chart hanging plate ofthe corresponding page is internally conducted and produces force the same as that produced by the magnet device on the main panel, so that the two chart hanging plates are separated, and the function of searching for the page in the turned pages is realized.

Description

technical field [0001] The invention relates to a teaching article, in particular to a wall chart device for ideological and political education.
