Economic management display device

Abstract

The invention discloses an economic management display device comprising a shell, wherein multiple first through holes are arranged on the front side surface and multiple first grooves are arranged onthe rear side surface; multiple separating plates which are connected in the shell in a spaced way to separate the shell into multiple display areas, wherein any one display area is correspondingly provided with one first through hole and one first groove; multiple display mechanisms, wherein one display area is correspondingly provided with one display mechanism, any one display mechanism comprises a drum which is horizontally positioned at the lower end of the first through hole, a cloth tape which is wound on the drum, a first slide block which is slidably arranged in the first groove, anda connecting rod which connects the start end of the cloth tape and the first slide block; multiple transmission mechanisms, wherein one display mechanism is correspondingly provided with one transmission mechanism; and a rotating mechanism. Adjustment of multiple height data can be completed by rotating the third rotating shaft with no requirement for adjusting the height of each display windowmarking line one by one so as to save the classroom teaching time; besides, the economic management display device has simple structure and high operability and practicability.

Description

technical field [0001] The invention relates to the technical field of teaching aids. More specifically, the present invention relates to an economic management display device. Background technique [0002] In the process of teaching economics and management, teachers of economics and management always need to carry out some statistics and comparisons of data. For convenience, many teachers do not draw column charts to explain, but only use oral form to tell students, which causes students to It is difficult to understand. For this reason, many teachers manually draw column charts to display and explain in detail the statistics and comparison of data. The traditional way of drawing column charts is for teachers to manually draw repeatedly on the blackboard. Erased, not retained, but redrawn when needed, burdens the teacher's teaching and delays the limited time of the classroom.

[0002] In the process of teaching economics and management, teachers of economics and management always need to carry out some statistics and comparisons of data. For convenience, many teachers do not draw column charts to explain, but only use oral form to tell students, which causes students to It is difficult to understand. For this reason, many teachers manually draw column charts to display and explain in detail the statistics and comparison of data. The traditional way of drawing column charts is for teachers to manually draw repeatedly on the blackboard. Erased, not retained, but redrawn when needed, burdening teachers and delaying limited classroom time

[0003] In order to solve the above problems, people have introduced economic management teaching display devices in the teaching process. The display devices in the prior art require teachers to manually adjust each column marking line one by one during the display process, which is time-consuming and laborious. It is easy to shift under interference. After the display is completed, the teacher needs to manually return each column marking line one by one, and the operability is poor
