Problems solved by technology

[0003] However, when the general teaching projector is used by the operator, it is necessary to use tools to install the projector on the wall. The operation steps are cumbersome, and it is inconvenient for the operator to perform regular maintenance, which is not conducive to improving the use efficiency of the device; and , the device is generally directly exposed to the air, and the external dust ma...

Abstract

The invention relates to the field of screen-free projection devices for intelligent teaching, in particular to a screen-free projection device for intelligent teaching. The projection device comprises a main body mechanism, a fixing mechanism, an adjusting mechanism, a heat dissipation mechanism, a limiting mechanism and a cleaning mechanism; the fixing mechanism is shifted, then the fixing mechanism clamps and fixes the side wall of a projector, the adjusting mechanism is rotated, then the adjusting mechanism adjusts the placing angle of the projector, and the tedious steps that an operator needs to reinstall the projector are reduced; the heat dissipation mechanism is started, so that the heat dissipation mechanism dissipates heat of the working projector when rotating; the limiting mechanism is pressed and rotated, so that the limiting mechanism is separated from the main body mechanism, an operator can conveniently mount and dismount the projector, and dust prevention of the main body mechanism is facilitated at the same time; and when the fixing mechanism slides, gas in the cleaning mechanism is discharged out of the main body mechanism, so that the main body mechanism is convenient to clean, and meanwhile, the pressure of the fixing mechanism is also convenient to release.

Description

technical field [0001] The invention relates to the field of a projection device without a screen for smart teaching, in particular to a projection device without a screen for smart teaching. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0003] However, when the general teaching projector is used by the operator, it is necessary to use tools to install the projector on the wall. The operation steps are cumbersome, and it is inconvenient for the operator to perform regular maintenance, which is not conducive to improving the use efficiency of the device; and , the device is genera...
