Abstract
A rear projection video communication media inside balloon is provided. A projector frame is hermetically mounted to a balloon. A projection screen is provided inside the balloon. A watchable transparent window is in front of the projection screen, and the projector frame is behind the projection screen. Ropes are provided between the projector frame and four corners of the projection screen for fixing, which provides assurance of distance and direction between the projector frame and the projection screen. A projector is equipped in the projector frame connecting with external circuit and various broadcast equipments through a lens projection signal, an electrical power cord and a signal line which are in front of the projector frame and extended out of the balloon. Light gas is supplied into the balloon when using to float in the air, and the balloon is fixed by stuffs like soft rope. The benefit of the utility model is that various applications is applicable, especially playing large screen video information in temporary ground. The rear projection video communication media inside balloon of the utility model has a simple structure which is easy to install and use.
Description
Technical field the utility model relates to a kind of balloon communications media, rear-projection video transmission medium in especially a kind of balloon.
Background technology is present, along with further developing of market economy, the application of life outdoor videos communications media such as large screen television etc. is more and more extensive, but video transmission medium such as the outdoor large screen television of prior art can only be fixed on a place, can not move, powerless for the occasion that some temporary needs large-screen videos show, this is its shortcoming.
The summary of the invention the purpose of this utility model is to provide a kind of movably life outdoor videos communications media, rear-projection video transmission medium in promptly a kind of balloon.
The technical scheme that its technical problem that solves the utility model adopts is: balloon and the sealing of projection frame are installed, projection screen is arranged in the balloon, screen front is that transparent window can be for watching, the screen back is and the projection frame of the common sealing of balloon, stay cord is set with distance and angle between fixing and assurance projection frame and the screen between projection frame and the screen.Projector is contained in the projection frame, lens projects signal by the frame front, power line and holding wire stretch out that balloon is outer to be connected with external circuit and various playback equipment, during use balloon are filled with light gas to make it to fly in the air, and with tightrope one class material balloon are fixed.
The beneficial effects of the utility model are: can be in various use occasions, and particularly the large-screen video information is play in the beta site, and is simple in structure, easy to install.
Description of drawings further specifies the utility model below in conjunction with drawings and Examples.
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structure enlarged diagram of the utility model projection frame
