The rotation of the double-shaft motor drives the rotation of two lead screws, and the rotation of the two lead screws drives two aluminum alloy frames to move closer to each other through two sliding rods. When the two aluminum alloy frames come into contact, the sliding rod contacts a travel switch at this time, and the travel switch automatically controls the double-shaft motor to turn off, thereby achieving the purpose of automatically closing and sealing the aluminum alloy door frame in strong wind and rain weather or when the outside air haze concentration is relatively high, and achieving the purpose of protecting the facilities and personnel inside the building.

[0019] 2. The automatic sealing structure for aluminum alloy doors and windows, by setting connection boxes, installation cylinders, sliding mesh cylinders, activated carbon particles, protective nets, first sealing plates, second sealing plates, ventilation holes, iron blocks and operation panels, enables the aluminum alloy doors and windows to still have the performance of ventilation after automatically closing and sealing downward in strong wind and rain weather or when the outside air haze concentration is relatively high. When the sliding rod drives the first sealing plate and the second sealing plate to move inside the connection box, several protective nets correspond to and communicate with several installation cylinders. Moreover, it can fully purify the outside air through activated carbon particles, improving the air quality inside the building. At the same time, when it is necessary to replace the activated carbon particles, operate the two operation panels with force and pull them outwards to achieve the quick disassembly of the installation cylinder, and the sliding mesh cylinder can be quickly disassembled under the action of the insertion strips, thereby achieving the quick replacement of the activated carbon particles, providing convenience for the operator.
