By turning the knob 48, the opening and closing and opening size of the entire skylight can be controlled.

[0042] The sealing sheet 49 can prevent the escape of cold air due to the loose fit between the movable glass 41 and the inner wall of the movable frame 2, thereby effectively reducing the efficiency of cold air escape. The combination of the first sealing strip 50 and the second sealing strip 51 provided between the movable glass 41 and the movable frame 2 can enhance the sealing between the movable glass 41 and the fixed glass 3, thereby preventing cold air from escaping from the gap between the movable glass 41 and the movable frame 2.

[0043] When the movable frame 2 is completely closed and fits with the fixed frame 1, the fixed ring 52 drives the sealing ring 53 to be inserted into the interior of the fastening seat 54, so that the protrusion on the inner wall of the fastening seat 54 squeezes the sealing ring 53, and then the sealing ring 53 and the inner wall of the movable frame 2 are tightly fitted, thereby effectively sealing the gap between the fixed frame 1 and the movable frame 2, and effectively preventing the escape of cold air.

[0044] When the movable frame 2 is to be opened as a whole, the two sets of electric push rods 55 are started at the same time to synchronously push the rack 56 to move, so that the transmission gear 58 meshing with the rack 56 rotates, and the rotation of the transmission gear 58 drives the fixedly connected worm 59 to rotate synchronously, thereby making the worm wheel 61 meshing with the worm 59 rotate synchronously, and the rotation of the worm wheel 61 drives the fixedly connected movable frame 2 to rotate, thereby achieving the effect of opening the movable frame 2 as a whole, and the opening and closing angle of the movable frame 2 as a whole can be controlled by controlling the moving distance of the rack 56.
