ABSTRACT:
The present invention is concerned with an innovative design of venetian blind providing the functions of sun screening, light regulating, the prevention of burglary and beautiful appearance; in particular, the one which is easy to be assembled by consumers themselves. It is to unite and fix a lot of supporting seats in equal spacing on a fixed guide rail and then connect serially with a regulating shaft which is combined with a regulating wheel; the supporting seats are combined with a slat respectively and the top end of the slat is restricted and positioned by two fixing plates which allows the slat to turn. The regulating shaft is driven to rotate by the regulating wheel and then the supporting seats would drive in turn the slats to turn to adjust the angle of the slats of the venetian blind.
