Description

Shutter curtain

Technical Field

The invention relates to a blind curtain.

Background

The shutter curtain is mainly made of aluminum alloy and wood-bamboo baking varnish, has the characteristics of durability, normal freshness, easy cleaning, no aging, no fading, sun shading, heat insulation, ventilation, fire prevention and the like, is suitable for places such as high-grade office buildings, living rooms, hotels, villas and the like, and can be used for shielding openings of windows and doors so as to block light and keep privacy.

Along with the development of national economy, the requirement of people on the quality of life is improved day by day, the window decoration product is also developed rapidly, the louver is used as a product with rich page turning and dimming functions, the application demand is more and more, the early product is manually driven, the lifting and page turning of the louver product are realized through the pull rope and the plastic rod, the product is simple in structure and convenient to operate, but the rope is extremely easy to wear, the product is not long in use, and a multi-product structure scheme appears subsequently.

Traditional venetian blind includes the head rail, the lower rail, the venetian blind, an adjustment mechanism for adjusting the rising or decline of venetian blind and the blade angle that opens and shuts, adjustment mechanism includes stopper and winder, common for venetian blind stopper on the market at present mainly adopts the nut to move on the screw rod and realizes spacingly, can be very accurate set for the lower limiting position of production on the rise, but the product equipment is accomplished the back, can't adjust the spacing height of product, the condition of light leak appears when field application, need return the factory and carry out spacing adjustment, it is very inconvenient.

The present winder that is used for promoting tripe and control tripe reversal includes screw thread winder, bandlet winder, polished rod winder etc. and its defect that exists is:

1. the threaded winder is easy to disorder, mainly because the manufacturing accuracy of the die is insufficient, the specifications of the used lifting ropes are too many, the performance is extremely unstable, the applicable range of the winder is very small, the winder is basically eliminated in the shutter at present, and only Roman curtains and other products with low requirements on the position accuracy are adopted.

2. The flat belt winding is a product derived from a thread winder for improving the quality, but the flat belt is expensive to manufacture, and the thickness of the flat belt is large in size, so that the product is unbalanced, and the flat belt winding is not suitable for being adopted in large batch.

3. Polished rod winder is the most main application scheme on the market at present, and the technology is mature, and the stability of product is good, and the defect lies in that most of schemes all realize the lift and turn over page or leaf control of product, and two actions are by mutual interference.
