Remote control projection device based on network communication technology

Abstract

The invention discloses a remote control projection device based on a network communication technology. The device comprises a supporting assembly and a projection device. The projection device is installed at the upper end of the supporting assembly. A threaded head is mounted at the upper end of a second supporting rod; when the threaded head is in threaded rotary connection with a threaded hole, a limiting block is firstly compressed, when a host is rotated for one circle, the limiting block rebounds under the elastic potential energy of a spring, the limiting block can be clamped into a limiting hole, the threads on the outer surface of the thread head form a circle, the host can be quickly connected with a second supporting rod, convenience and quickness are achieved, after the host is connected with a second supporting rod, and when the host needs to adjust the elevation angle and the depression angle according to the projected picture, a round nut can be rotated to loosen the contact between a connector and a ball head, the ball head can be adjusted in the inner cavity of the connector, the adjustment of the elevation angle and the depression angle of the host can be facilitated, and the host can be fixed by reversely rotating the round nut after the projected picture is adjusted.

Description

technical field [0001] The present invention relates to the technical field of projection devices, in particular to a remote control projection device based on network communication technology. Background technique [0002] A projector, also known as a projector, is a device that can project an image or video 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. A network communication control device, a storage module and a control chip are installed inside the projector. The network communication control device is connected with the storage module, and the video and information are stored in the storage module through the network communication control device. The network communication control device is connected with the control chip. Projection can be controlled remotely. [0003] However, when the current projection device needs to be used, the projection device and the ...

Problems solved by technology

[0003] However, when the current projection device needs to be used, it is necessary to screw the projection device and the base to fix it. This fixing method is time-consuming and laborious. It requires the user to bend down and fix it one by one, which is extremely inconvenient to use.
