Computer teaching device

Abstract

The invention discloses a computer teaching device. The device comprises a supporting plate, a pair of lifting rods are vertically arranged on the upper surface of the supporting plate, a base is arranged above the lifting rods, a first groove is formed in the base, a screw is arranged in the first groove, one end of the screw is connected with a first motor arranged in the first groove, a threadbase is rotatably connected to the screw, a first connecting base is arranged on the thread base, a first connecting rod is hinged to the first connecting base, a second connecting base is hinged to the end, away from the first connecting base, of the first connecting rod, and the second connecting base is arranged on the bottom face of a displayer containing base. The device can sufficiently meetthe observation need of students on all corners in a room, the teaching efficiency of a classroom can be greatly improved, and the problems that when an existing current multi-medium teaching deviceis used, the visual angle is limited, the definition is low, and use is not convenient are solved.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to a computer teaching device. Background technique [0002] Computer inventor John von Neumann. Computer is one of the most advanced scientific and technological inventions in the 20th century. It has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. Its application field has expanded from the initial military scientific research application to various fields of society, and has formed a huge computer industry, which has driven technological progress on a global scale, which has triggered profound social changes. Computers have spread throughout general schools and enterprises. Public institutions have entered the homes of ordinary people and become an indispensable tool in the information society. [0003] At present, when using computer teaching, it is often necessary to adjust the angle of the ...

Problems solved by technology

[0003] At present, when using computer teaching, it is often necessary to adjust the angle of the teaching device. Most of the existing computer teaching devices are directly fixed on the base. The angle of the display in the device cannot be adjusted, and it cannot be lifted. Due to certain limitations, it is inconvenient to carry out teaching demonstrations. At the same time, most of the existing computer teaching devices are realized with the aid of auxiliary instruments. Due to the large interior space of the classroom, the instruments and equipment used in computer teaching are generally small in size, so that Students who are far away from the instruments and equipment cannot clearly observe the effects demonstrated by the teaching instruments
