Computer teaching display device

Abstract

The present invention provides a computer teaching display device. The device comprises a hollow box body, and a driving shaft is arranged in the middle of the box body; the driving shaft is connectedwith a Z-shaped rod through a bevel gear set; the Z-shaped rod is rotatably connected with the box body, the right end of the Z-shaped rod is rotatably connected with a sleeve, the sleeve is slidablyconnected with an L-shaped rod, the L-shaped rod and the right end of the L-shaped rod are slidably connected with a first connecting rod, the first connecting rod is fixedly connected with the box body, and the upper side of the L-shaped rod is slidably connected with a second connecting rod. According to the invention, the problem that the existing teaching display device can only display one surface of the teaching model, the model cannot be displayed in all directions, the display model cannot be fixed, students in the rear row cannot observe the model, the teaching quality and efficiencyare affected, the teaching tool storage function is lacked, teaching tools are prone to being lost, and the teaching display device is inconvenient to move are solved.

Description

technical field [0001] The invention relates to the teaching field, in particular to a computer teaching display device. Background technique [0002] When computer teachers are teaching, they often need to display some teaching models in the classroom. Through the display of teaching models, it is convenient for students to better understand the relevant knowledge and effectively improve students' learning efficiency. Existing model display devices for computer teaching often need to display some teaching models in the classroom. The existing teaching display devices have unreasonable structural design and single function. They can only display one side of the teaching model, and cannot comprehensively view the model. Demonstration, the display model cannot be fixed and the students in the back row cannot observe the model. The display effect is not good, which affects the teaching quality and efficiency, lacks the storage function of teaching tools, and the teaching tools ...
