Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, the flexible Fresnel optical screen of the application, including Fresnel optical diaphragm 1, elasticity are even
Connection mechanism and screen construction frame.Described flexible connection mechanism one end is connect with Fresnel optical diaphragm 1, the other end and screen knot
The connection of structure frame.Flexible Fresnel optical screen.Wherein flexible connection mechanism is that can generate the mechanism with deformation tendency is restored,
It can be realized using the spring mechanism used in the prior art, the modes such as tension spring mechanism.The application is by flexible Fresnel optical panel
Curtain resolves into Fresnel optical diaphragm 1, flexible connection mechanism and screen construction frame three parts, and three parts, which can be used, detachably to be connected
The mode connect, so that three parts are separated packed and transported, and using the flexibility of Fresnel optical diaphragm 1, by it along full-size
It after the bending of direction, is transported, screen assembling is finally carried out at user.Since the size of various pieces after splitting subtracts significantly
It is small, and flexible Fresnel optical screen can further decrease size by being bent.Various pieces after splitting in this way are all
Narrow elevator can be entered, easily registered one's residence by elevator traffic realization, utilize flexible connection mechanism by Fresnel after registering one's residence
Optical diaphragm 1 is connected with screen construction frame is combined into complete screen, and using flexible connection mechanism elastic restoring force make by
Optical diaphragm even up it is whole, to form whole smooth screen.
