Description
Technical field
The present invention relates to shutter technical field, specially a kind of closed upper rail system of fine work shutter.
Background technique
Shutter is a kind of style of window, originating from China.In Chinese ancient architecture, there is mullion window, from the Warring states to the Chinese
There is utilization for each dynasty.Vertical item is referred to as mullion window, and there are also items anyhow, is sleeping lattice window.Sleeping lattice window, that is, shutter
A kind of original style, it may also be said to which it is the original state of shutter, different from the quality of curtain softness, is adopted as louvers of jalousie
With the materials such as wood, glass and aluminium alloy, therefore the erosion of sunlight, wind and rain, dust can be kept out, and easy to clean, pass through light
Adjusting, shutter can also change pleasing sense for modern succinct spatial band；The selection of multiple color more makes shutter
It combines together with the style of home decoration.
But existing upper rail of louver window system lock is poor, can not be effective dust-proof, leads for a long time using dust is more
Cause system easy break-down, and lifting speed is slower, reduces user experience, drawstring is easy to be Chong Die with ladder rope, and shutter is caused to lose
Control, curtain sheet can not quantify to rotate, it has not been convenient to which user uses, for this purpose, we have proposed a kind of closed upper rail systems of fine work shutter
System is to solve the above problems.
