Abstract
Description
technical field
[0001] The invention relates to a blind with blades arranged longitudinally and the opening angle of the blades can be adjusted. Background technique
[0002] The louvers have the function of shading and ventilation; just like the shutters of the weather observation station, the louvers with horizontal blades also have the function of blocking rainwater. When installing shutters on office or residential indoor windows, the requirements are different. In order to enjoy the outdoor sunshine, or to improve indoor ventilation, if more cool wind or fresh air is needed to blow into a stuffy room or a room with turbid air, people need to make the blinds so that they can turn their blades to adjust the blades. Angled blinds too. Among the blinds with adjustable blade inclination angle, the blade width is wider (usually about less than the thickness of the wall at the window), and the blinds with vertical blades are better-the blade can be adjusted almost in the ran...

Embodiment Construction
[0018] A shutter with longitudinal blades (reference figure 1 , 2 , 3, 4, 10), the shutters include a number of synchronously rotating blades 7 with cavities inside or filled with thermal insulation materials in the cavities, and are located on the same plane when turned to the closed state, fixedly installed on these The rotating shaft 71 on the blade 7 overlapping the center line of the blade width is fixed relative to the window sill to support the upper and lower bearings (73, 72) of the rotating shaft 71. In the present invention, when the blades 7 turn to the closed window state, there is a rubber or artificial rubber caulking strip 70 that fills the gap between the two sides between the opposite sides of the two adjacent vanes 7. One side of 70 is close to the side of wherein a blade 7, and its cross-section that is arranged vertically on the other side is the extrusion bar 701 that is comb-tooth shape, and under the unextruded state of this extrusion bar 701, its comb...
