Display device for economics

Abstract

The invention discloses a display device for economics, and the display device comprises a supporting mechanism; a lifting mechanism is arranged at the top of the supporting mechanism, a shell is arranged at the top of the lifting mechanism, a motor is installed at the bottom of the right side of an inner cavity of the shell, an output shaft of the motor is in transmission connection with a lead screw, and the left end of the lead screw is rotationally connected with the shell; and the surface of the lead screw is in threaded connection with a screw sleeve. According to the invention, the motor is started, and an output shaft of the motor finally drives a main display board to move upwards, so display can be conducted on the surface of the main display board; a rotating rod is rotated outwards by 90 degrees, the top of a U-shaped frame makes contact with the surface of the main display board, and then an auxiliary display board can be unlocked; the handle is pulled upwards, so the auxiliary display board can be unfolded. The display device for economics has the advantages of being adjustable and convenient to store, the display area of the display device is increased through the arrangement of the auxiliary display plate, and the flexibility of the display device is improved.

Description

technical field [0001] The invention relates to the technical field of economics, in particular to a display device for economics. Background technique [0002] Economics is a discipline that studies various economic activities and various corresponding economic relations and the laws of operation and development of human society at various stages of development. The core idea of ​​economics is material scarcity and effective use of resources, which can be divided into two categories: The main branches are microeconomics and macroeconomics.

Problems solved by technology

[0003] In the teaching process of economics courses, in order to display the teaching information to students more intuitively, it is necessary to display the teaching information to the students through the display device. Because the teacher's explanation and display content is different, the required display area is also different, and most of the existing display devices It is an integrated device and does not have the function of adjustment, resulting in a fixed display area of ​​the display device, which reduces the flexibility of the display device and affects the display effect. At the same time, the existing display device takes up a lot of space when it is not in use
