[0002] The skylights commonly used in buildings today are mostly made of aluminum alloy or steel structure combined with glass. The glass is installed on a metal frame, and the window sash is opened and closed by pushing and pulling the metal frame.

[0003] Most existing skylights use a single-board structure. For some large lighting areas, if the single-board structure is still used, the wind pressure acting on the surface is large when it is opened, and a support with a better and more stable structure is needed to stabilize the skylight. There are some telescopic skylights in the prior art. Since the skylights are generally inclined or horizontal when they are built, water seepage is easy to occur at the skylights in rainy seasons, which leads to the skylights having a waterproof effect.

The width of the sealing strip 42 gradually decreases in the direction approaching the upper surface of the sealing groove 41 and is gradually provided away from the sealing groove 41 , so as to facilitate deformation processing of the sealing strip 42 .

[0054] The mounting strip 40 is provided with two vertically distributed through-holes 43, and a traction rope 44 is inserted in the through-holes 43. One end of the traction rope 44 is connected to the top of the sealing strip 42 close to the mounting strip 40, and the other end descends through the through-hole 43 away from the side of the window panel 10 and reversely passes through the through-hole 43 close to the side of the window panel 10 to be connected with a lifting block 45.

[0067] When the lower lighting plate 30 slides relative to the guide bar 11, the negative pressure extractor 46 generates negative pressure to drive the lifting block 45 upward relative to the window plate 10, and drives the sealing strip 42 and the sealing groove 41 to separate through the traction rope 44;

[0068] When the lower lighting plate 30 is reset, the negative pressure extractor 46 stops working, the lifting block 45 is reset under the action of its own gravity, and the sealing strip 42 and the sealing groove 41 are re-matched to form a sealing structure.
