Computer teaching device

Abstract

The invention discloses a computer teaching device. The computer teaching device comprises a table body, wherein a display screen is disposed on the upper surface of the table body, and the lower surface of the table body is fixedly connected with a cabinet body; the cabinet body is internally provided with a host, and through holes are formed in the rear side of the cabinet body and exhaust fansare fixedly connected to the rear side of the cabinet body through the through holes; the inner wall of the cabinet body is fixedly connected with a dust removing device, and the dust removing devicecomprises a fixing plate; the right side of the fixing plate is fixedly connected to the inner wall of the cabinet body, and a connecting plate is fixedly connected to the left side of the fixing plate; and the surface, near the top, of the connecting plate is connected with a first swing arm through a pin shaft. Through matching usage of the above structure, the computer teaching device solves the problem that the working environment of a computer is deteriorated, a large amount of accumulated dust further reduce the heat dissipation efficiency, and in the high temperature working environment, the aging of internal components of the computer can be accelerate due to the fact that in the actual use process, the dust is still accumulated at dead angles in the cabinet body, and the dust accumulates in a large amount after long-term use.

Description

technical field [0001] The invention relates to the technical field of computer teaching, in particular to a computer teaching device. Background technique [0002] Multimedia teaching means that in the teaching process, according to the teaching objectives and the characteristics of the teaching objects, through teaching design, rationally select and use modern teaching media, and organically combine with traditional teaching methods, participate in the whole teaching process together, use various media information For students, a reasonable structure of the teaching process is formed to achieve the optimal teaching effect; due to the characteristics of the internal components of the computer, it needs to be used in a dust-free environment and in the case of ventilation and heat dissipation, and there will still be a large number of problems in traditional computer teaching. Dust, chalk debris and the above-mentioned situation of accumulation of dust and heat accumulation s...

Problems solved by technology

The beneficial effects of this utility model are: it is convenient for teachers to use in teaching, and at the same time, it can ensure a high degree of cleanliness of the computer, as well as the heat dissipation effect, prolong the service life of the computer, and ensure the normal progress of teaching demonstrations. However, in the actual use process, due to the Dust will still gather in dead corners. After long-term use, a large amount of dust will accumulate, which will deteriorate the working environment of the computer, and a large amount of accumulated dust will also reduce the heat dissipation efficiency. In a high-temperature working environment, it will accelerate the aging of the internal components of the computer.
