Referring to fig. 2-3, the multi-step sealing structure of the casement window comprises an outer profile 100, an inner profile 300 and a heat insulation cavity 200, wherein the heat insulation cavity 200 is arranged between the outer profile 100 and the inner profile 300, an outer profile sub-part 400 is arranged at the bottom of the outer profile 100, and the outer profile sub-part 400, the outer profile 100, the heat insulation cavity 200 and the inner profile 300 are connected in a staggered manner to form a multi-step.

In one embodiment, the outer profile sub-portion 400 is disposed at the bottom of the outer profile 100 to form a first step, the bottom of the outer profile 100 forms a second step, the bottom of the thermal insulation cavity 200 and the bottom of the inner profile 300 are located on the same plane to form a third step, and the first step, the second step and the third step are gradually climbing upwards.

Specifically, the outer profile sub-portion 400 is an extension section formed by extending downward along the outer side wall of the outer profile 100.

Specifically, a fixing profile 700 is disposed below the outer profile 100, and the fixing profile 700 is a window frame.

Specifically, a first sealant 810 is disposed between the outer profile sub-portion 400 and the fixed profile 700.

In one embodiment, a first C-shaped installation groove is formed inside the extension section, and the first C-shaped installation groove can be used for installing a first sealant 810, and when the window sash is closed, a first layer of sealing structure is formed by the first sealant 810 and the fixing section bar 700 arranged below the outer section bar 100.

In another embodiment, the first C-shaped mounting groove is disposed at the outer side of the fixing profile 700, the first sealant 810 is disposed in the first C-shaped mounting groove, and when the window sash is closed, the first layer of sealing structure can be formed by the first sealant 810 and the outer profile sub-portion 400.

Specifically, a second sealant 820 is disposed between the outer profile 100 and the fixing profile 700.

In one embodiment, the second sealant 820 is installed on the outer profile 100 through a second C-shaped installation groove formed on the inner sidewall of the outer profile 100, and when the window sash is closed, the second sealant 820 is matched with the fixing profile 700 to form a second layer of sealing structure.
