[0075] See also Figure 8 and Figure 9 , further comprising a tensioning device 36, a lower roller 336 being disposed on the tensioning device 36, and the tensioning device 36 comprising a sliding frame 361 and an adjusting mechanism 362;

[0076] The sliding frame 361 is slidably matched with the adjustment mechanism 362 so as to move up and down. The lower roller 336 is rotatably arranged on the sliding frame 361 through a bracket.

[0078] The working principle of the clutch mechanism: move the control handle 3122, the internal manipulator 311 moves accordingly, and pull the lifting rope 321 to complete the lifting of the blade. The baffle 3372 corresponds to the first spring foot 33731 and the second spring foot 33732. When the spring 3373 rotates on the upper roller 335, the axle of the upper roller 335 drives the spring 3373 to rotate a certain angle accordingly. When the second spring foot 33732 contacts one side of the baffle 3372 and continues to rotate, the second spring foot 33732 drives the baffle 3372, and the baffle 3372 drives the connecting shaft 3371 to rotate a corresponding angle, and drives the flip shaft 331 to rotate a certain angle accordingly, that is, rotate through the same angle to realize the flipping of the blade 21.

[0079] When the blade 21 flips to the limit, and then continues to pull the blade flipping traction rope 20, the second spring foot 33732 is in a blocked state by the lower baffle 3374. The second spring foot 33732 is blocked by the lower baffle 3374 and forces the spring 3373 to relax, that is, the upper roller 335 is no longer tightly engaged, and the second spring foot 33732 will not continue to drive the baffle 3372 to rotate, the connecting shaft 3371 is also in a stationary state, and the upper roller 335 is in an idling state because its wheel axle is not tightly held by the spring 53. At this time, continuing the lifting operation is also more labor-saving.

[0080] Since the blade 21 can be flipped in the opposite direction to the above, it is only necessary to operate the external manipulator 312 in the opposite direction, so it will not be described in detail.

[0081] The working principle of the tensioning device is as follows: when the lower roller 336 is driven upward by the flip rope 33, the sliding frame 361 is pulled in the opposite direction under the action of the tensioning spring 3623, so that the flip rope 33 is in a tensioned state, ensuring that there is sufficient friction between the flip rope 33 and the two rollers, thereby ensuring the reliability of the flip operation.

[0082] The utility model applies "factory"-shaped blades to a fully shading closed built-in venetian blind insulating glass with single-side control. When a group of blades of the venetian blind are adjusted to the extreme degree of the closed state through the 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 blind insulating glass and greatly reducing the shading coefficient, thereby improving the energy-saving performance of the built-in venetian blind insulating glass and effectively protecting user privacy.

On the basis of the technical solutions disclosed in the present invention, technicians in this field can make some substitutions and deformations of some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present invention.
