The invention discloses a model display teaching device with an adjusting and switching structure for economics, and the device comprises a pedestal, a motor, a first screw rod, a second screw rod, and a gear, wherein the pedestal is in shaft connection with a guide rod, the guide rod is sleeved with a display cylinder, the top of the display cylinder is fixedly provided with the motor in an embedded manner, and the output end of the motor is connected with a guide shaft. The first screw rod is connected to one end of the guide shaft, the first screw rod penetrates through the top of the guiderod in a threaded mode, a storage groove is formed in the outer side of the display cylinder, a display frame is placed in the storage groove, an installation rod is arranged on the inner side of thedisplay frame, a display board is connected to an inner shaft of the display frame, and an installation plate is fixed to the outer side of the display cylinder. The model display teaching device with the adjusting and switching structure for economics can be telescopically used, height adjustment and folding and unfolding are facilitated, meanwhile, rotary multi-angle display can be achieved, the display area is increased, and the display content is switched.
Description
technical field [0001] The invention relates to the technical field of economics, in particular to a model display teaching device with an adjustment switching structure for economics. Background technique [0002] Economics includes microeconomics and macroeconomics. It mainly 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 importance of economics requires the cultivation of a large number of Talents, in the teaching process of economics, can be represented by equations with diagrams or words, and then need to use model display teaching devices for intuitive learning. However, the existing model display teaching devices have the following problems in use: [0003] Due to the large number of students in the teaching process, in order to facilitate the students to watch and facilitate the teaching operation of teachers of different heights, the mod...
