At this time, the lifting rope 32 on one side of the inner lifting controller 312 descends, and the lifting rope 32 on the side of the venetian blind 2 rises, driving the blades 21 of the venetian blind 2 to rise. If a lowering operation is required, the opposite is true.

[0060] The flipping working principle is as follows: the user pulls down the outer flip controller 422, driving the inner flip controller 421 to descend at the same time, the flip pull rope 43 drives the first roller 451 to rotate, the first roller 451 drives the rotating shaft 44 to rotate, the rotating shaft 44 drives the rotator 471 of the flip seat 47 to rotate, the rotator 471 drives a pair of main ropes of the flip ladder rope 41 to move up and down, and then the ladder rope 411 drives the blade 21 to rotate.

[0061] In this embodiment, the direction-changing wheel 34 is arranged in the turning seat 47, and the two are combined into one, which makes the structure more compact. This is a conventional setting and the specific structure will not be repeated.

[0062] The utility model applies "factory"-shaped blades to closed, fully shading built-in venetian blinds and insulating glass. When a group of blades of the venetian blinds are adjusted to the extreme degree of the closed state through the flip adjustment control mechanism, the blade body is perpendicular to the horizontal plane, and the rear edge of the lower bent portion overlaps the top surface of the upper bent portion of the lower blade. As a result, the width of the closed gap between adjacent blades is significantly reduced, which can completely block outdoor sunlight from entering the room, greatly improving the overall shading performance of the built-in venetian blinds and insulating glass, and greatly reducing the shading coefficient, thereby improving the energy-saving performance of the built-in venetian blinds and insulating glass, and effectively protecting user privacy.
