Task of the present utility model, it is the magnetic rolling film that proposes in the class hollow glass, to roll up film and magnetic transmission mechanism and be contained in the internal clearance in the following hollow glass of 12mm, under the prerequisite of guaranteeing the hollow glass sealing, by external magnetic part Contact Transmission not, directly regulate the interior spool of control hollow glass with film take-up or expansion, control spool simultaneously and rotate rolling under the straight state or launch film keeping as far as possible, the dual adjustable function that hollow glass is had simultaneously regulate heat-proof quality and regulate light.

Magnetic rolling film in a kind of hollow glass of the utility model is to make like this; Some winding films with specific function are installed on the hollow spool that the hollow glass top can rotate freely at one, suitable position studs with the magnetic part of several specific magnetic force directions in the spool, the magnetic direction that wherein is used to rotate the transmission magnetic part is for radially, correct position outside hollow glass is equipped with the magnetic part with radial magnetic field and directly drives spool rotation volume playing function film by magnetic force.When oversize or film is heavier when spool, the magnetic direction of inlaying the magnetic part that is used to keep spool to be in straightened condition in the spool is for axially, and inner or outside correct position is fixed with the magnetic part with axial magnetic field and makes it to keep straightened condition by the magnetic levitation spool at hollow glass.

Function film can adopt the high-strength and ageing resistance thin-film material of thickness less than 0.03mm, as polyester film, polycarbonate membrane or other organic film are base material, by be shaped preceding or moulding after it is handled, as multiple processing modes such as atomizing, dyeing, surface vacuum or magnetron sputtering platings.Make film have needed various function, as it is opaque to be similar to the frosted glass printing opacity, coats or catch the different color of depth degree, to comprising selective permeation from ultraviolet ray to infrared rays different-waveband light etc.

Magnetic rolling film in a kind of hollow glass of the utility model, simple in structure, there is not any indirect drive part, have high reliability and durability, can solve the volume film of in the hollow glass of widely-used little gap, packing into preferably and have the transmission problem.Make this class hollow glass only pack into need low-cost processes just can obtain various respective performances films after, can promote the energy-conservation or dimming function of hollow glass greatly, with the hollow glass that these simple glasses are made, can really have energy-conservationization, intelligentized relevant comprehensive function that modern architecture requires glass to have.

When the area of hollow glass is very big, when surpassing the length of run of monovolume film as glass in height, several film spools that can in glass, be arranged in parallel, the volume of controlling film outside glass synchronously or is respectively put.

Improving aspect hollow glass energy-conservation, adopt hollow glass that the utility model makes each in season degree all might obtain best energy-saving effect.For example, hollow glass with the conventional clear glass making, the effect that its radioresistance is conducted heat is relatively poor, be coated with silver and other composition low radiation films if load onto in glass inside, after when summer, sunlight was strong, film being launched, most of solar radiant heat retaining can be conducted heat at air-flow outdoor and that reduce in the hollow glass, be again a good window shade simultaneously, and have permeability and crypticity preferably.In the winter time, film take-up can be made in most of sun heat radiation inlet chamber when daytime, sunlight was strong, launch film evening, and it is outdoor well to stop indoor heat to be lost to forms of radiation again.

Aspect the dimming behavior that increases hollow glass, adopt the utility model just can realize the dimming effect that glass and curtain are integrated.For example, independently film of the different difference of two covers can be installed in hollow glass, a cover film is that inferior light printing opacity is opaque, and another set of is dark light tight, becomes the day and night curtain that day and night all is suitable for.Also can coat the color of the different depths in the zones of different in same the film that twin shaft volume is put, when film launches different zones in glass, light transmittance is change thereupon also, reaches to make hollow glass have the effect of stepless dimming.
