Abstract
The invention discloses a mobile projection curtain device, and belongs to the projection device technology field. The mobile projection curtain device comprises a support and a curtain telescoping box. Sound boxes are installed at two ends of the curtain telescoping box. Two reels, two curtains and two driving devices are installed in the curtain telescoping box. One curtain winds one reel. One driving device controls one reel. The reels are arranged side by side in parallel. One end of each reel is equipped with a coaxial motor drive. The curtain telescoping box is equipped with two curtain outlets. Each curtain corresponds to one curtain outlet arranged between two reels at the bottom of the curtain telescoping box. The support and a pillar are in retractable design. Two curtain outlets are employed, curtain offset interference is avoided powerfully, the retractable support and pillar are employed, When a projection curtain is needed, the support and the pillar are drawn away for usage, when usage of the projection is finished, the support and the pillar are retracted, deploying and retracting are easy and the space is saved.

No matter universal along with computer applications, be work or life has all tended to electronization.The public places such as working and learning we often use projector, by he the working document in computer or audio/video file can be rendered on giant-screen for collective viewing, thus realizing impact-share.Sometimes it is also required to play sound to reach various dimensions displaying effect by audio output apparatus such as audio amplifiers.The multimedia system including scialyscope is had at fixing meeting room or multi-media classroom, but out of doors or do not have to render on the wall of white background by scialyscope in the room of multimedia system, appearance along with present mobile projector curtain, just can directly multimedia system be disposed at any time, present curtain is all with Collapsible rack and flexible curtain, directly lays and just can use.
In order to well solve the problems referred to above, the present invention provides a kind of mobile projector curtain device.
Summary of the invention
It is an object of the invention to provide a kind of mobile projector curtain device, adopt two curtain outlets, strong avoids curtain dislocation interference, support that employing can be stretched and pillar, when needs use projection screen, pull open support and pillar uses, after using, support and pillar are shunk, it is prone to folding and unfolding, save space, present configuration is simple, reasonable in design, by arranging audio amplifier on mobile curtain, sound-playing function can be provided very easily, without still further carrying installation audio amplifier, avoid on-the-spot nervous layout and carry with various cumbersome apparatus, time saving and energy saving, convenient and practical.
The technical solution adopted for the present invention to solve the technical problems is: a kind of mobile projector curtain device, including the flexible box 3 of support 1, pillar 2 and curtain, it is characterised in that: flexible box 3 two ends of described curtain are provided with audio amplifier 4.
Being provided with 5, two pieces of curtains 6 of two spools, two driving devices 7 in the flexible box 3 of described curtain, each spool is wound around one piece of curtain, each driving device controls a spool.
Described spool 5 is placed in parallel two row side by side, and one end of each spool is designed with coaxial motor and drives.
The flexible box 3 of described curtain is provided with two curtains outlets 8, the corresponding curtain outlet of each curtain, is opened in bottom the flexible box 3 of curtain between two spools 5.
Described support 1 and pillar 2 all design for telescopic type.
The invention has the beneficial effects as follows: 1, due to this mobile projector curtain device, adopt two curtain outlets, strong avoids curtain dislocation interference, support that employing can be stretched and pillar, when needs use projection screen, pull open support and pillar uses, after using, support and pillar are shunk, it is prone to folding and unfolding, save space, present configuration is simple, reasonable in design, by arranging audio amplifier on mobile curtain, sound-playing function can be provided very easily, without still further carrying installation audio amplifier, avoid on-the-spot nervous layout and carry with various cumbersome apparatus, time saving and energy saving, convenient and practical；
2, owing to being provided with 5, two pieces of curtains 6 of two spools, two driving devices 7 in the flexible box 3 of described curtain, each spool being wound around one piece of curtain, each driving device controls a spool.It is divided into relatively independent ground two set curtain device, meets different broadcasting demands；
3, owing to described spool 5 is placed in parallel two row side by side, one end of each spool is designed with coaxial motor and drives.Two pieces of curtains can not have displacement, so spool is in correspondence with each other, each employing coaxial motor steadily pulls open curtain respectively simultaneously, it is easy to play；
4, owing to the flexible box 3 of described curtain is provided with two curtains outlets 8, the corresponding curtain outlet of each curtain, it is opened in bottom the flexible box 3 of curtain between two spools 5.Being provided with two curtain outlets, strong avoids curtain dislocation interference；
5, owing to described support 1 and pillar 2 all design for telescopic type.When needs use projection screen, pull open support and pillar uses, after using, shunk support and pillar, it is easy to folding and unfolding, saved space.
