A demonstration projection device for a multimedia conference management platform

Abstract

The invention discloses a demonstration projection device for a multimedia conference management platform. The device comprises a demonstration frame, a support plate, a mounting frame, a projector and a limiting device; the support plate is arranged above the demonstration frame; the mounting frame is arranged on the support plate; the projector is fixedly arranged on the mounting frame; and thelimiting device is arranged under the demonstration frame. The position of the projector is conveniently adjusted on height; when the direction of the projector needs to be changed, a swing rod is poked to rotate, and the direction of the projector is changed; a first motor drives a driving roller to move, and drives the projector to move left and right to achieve fine adjustment according to theactual position in a multimedia conference room to prevent the troublesome step of completely shifting the demonstration frame; and compared with the prior art, the position of the projector is not fixed, and the projector is mounted on the demonstration frame to achieve movement to prevent the condition of needing to mount multiple projectors in multiple multimedia conference rooms.

Description

technical field [0001] The invention relates to the technical field of multimedia projection devices, in particular to a demonstration projection device for a multimedia conference management platform. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen, and can be connected to a computer, game console, DV, etc. through different interfaces to play corresponding video signals. Generally, multimedia conference rooms use projectors to complete the display of pictures or videos, but the existing devices of this type contain various devices with different performances that are relatively independent. For example, there are independent electronic whiteboards and independent projectors on the market. , the projection devices used in multimedia conferences in the prior art are generally fixed by hanging them, so each conference room needs to be equipped with such devices, and the installation is cumbersom...

Problems solved by technology

Generally, multimedia conference rooms use projectors to complete the display of pictures or videos, but the existing devices of this type contain various devices with different performances that are relatively independent. For example, there are independent electronic whiteboards and independent projectors on the market. , the projection devices used in multimedia conferences in the prior art are generally fixed by hanging them, so each conference room needs to be equipped with such devices, and the installation is cumbersome and has relatively large limitations. In addition, since the position of the fixedly installed projector cannot be moved, it cannot achieve the purpose of adjustment when it needs to be adjusted; finally, when the projector needs to change its direction, it generally needs to install a steering device on the suspension rod, causing the suspension rod The load is too heavy; for this reason, we provide a multimedia conference management platform with a presentation projection device to solve the problems raised in the above-mentioned background technology
