Computer network teaching device

Abstract

The invention discloses a computer network teaching device. The device comprises a baseboard, a U-shaped board is fixedly connected to the upper surface of the baseboard, a rotating device is clampedto the upper surface of the U-shaped board, a display screen is fixedly connected to the top of the rotating device, a first bevel gear is clamped to the outer surface of the rotating device, a secondbearing is clamped to the side face of the U-shaped board, and a second rotary shaft sleeves the inner surface of the second bearing. According to the computer network teaching device, springs downwards jack the rear sides of the upper surfaces of movement rods through pulleys, so that clamping blocks are re-clamped into clamping grooves, a turntable does not rotate anymore, and thus the displayscreen does not rotate any more; the angle of the display screen is adjusted without driving of a motor, thus electric energy is saved, the rotating angle of the display screen is manually adjusted, thus rotation of the display screen is easier to control, the situation that the rotating angle of the display screen is too large or too small is avoided, a teacher does not need to make secondary adjustment, the time of the teacher is saved, and convenience is brought to the teacher.

Description

technical field [0001] The invention relates to the technical field of computer teaching, in particular to a computer network teaching device. Background technique [0002] Teaching is a human-specific talent cultivation activity composed of teachers' teaching and students' learning. Through such activities, teachers guide students to actively and consciously learn and accelerate the mastery of basic cultural and scientific knowledge and basic skills with a purpose, in a planned and organized manner, and promote the comprehensive improvement of students' various qualities, so that they can become the people needed by society. The concept of teaching is abstracted and generalized from teaching phenomena and teaching practice, and the connotation of teaching also develops with the development of history. [0003] Most of the computer teaching devices are equipped with display screens, which are connected to the computer. The teaching content is displayed on the display screen...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a computer network teaching device, which solves the problem that most of the computer teaching devices are provided with a display screen, which is connected to the computer, and the teaching content is displayed on the display screen so that the teacher teaches the students to learn. For actual teaching needs, most of the existing display screens can be rotated, and the rotation of the display screen is often driven by a motor, which wastes electric energy, and when the motor is used to drive the display screen to rotate, the rotation angle of the display screen is not easy to control, so it is easy to make the display If the rotation angle of the screen is too large or too small, the teacher has to re-adjust the angle of the display screen, which wastes the teacher's time and brings inconvenience to the teacher
