[0039] As Figure 1 shown, this embodiment discloses an internal hinge type casement window structure, which includes: a window frame 2, a window sash 1 and a hinge 3. Among them, a window frame thermal break 5 is provided on the window frame 2, and a window sash thermal break 4 is provided on the window sash 1; that is, the window frame 2 includes an outdoor profile and an indoor profile, and the outdoor profile and the indoor profile are connected by a heat insulation strip to form the window frame thermal break 5; similarly, the profile structure of the window sash 1 also includes an outer profile and an indoor profile, and the outdoor profile and the indoor profile are connected by a heat insulation strip to form the window sash thermal break 4. The window sash 1 is hingedly installed on the window frame 2 so that the window sash 1 can be opened and closed.

[0040] One end of the hinge 3 is installed on the window frame 2 and is relatively close to the indoor side of the window frame thermal break 5, and the other end is installed on the window sash 1 and is relatively close to the indoor side of the window sash thermal break 4; that is, one end of the hinge 3 is installed on the indoor profile of the window frame 2, and the other end is installed on the indoor profile of the window sash 1.

[0041] In this embodiment, the hinge 3 is installed on the side of the window structure close to the indoor side, which can greatly improve the support strength of the hinge 3 and prevent the hinge 3 from deforming.

[0042] As Figure 1 shown, a first sealing strip 6 and a second sealing strip 7 are provided on the side of the window sash 1 close to the outdoor side, and the second sealing strip 7 is located between the hinge 3 and the first sealing strip 6. A third sealing strip 8 is provided on the window frame 2, and the third sealing strip 8 is relatively close to the indoor side of the hinge 3.

[0043] As Figure 3As shown in the figure, a foaming portion 23 extending towards the window frame 2 is provided on the first sealing strip 6; when the window sash 1 is opened, the foaming portion 23 is slightly rolled upwards, and when the window sash 1 is closed, the foaming portion 23 abuts against the outer edge of the window frame 2 and is thus straightened, forming a first seal from the outside to the inside. This first seal can, to a certain extent, prevent rainwater and dust from the outside from entering the room. When the window sash 1 is closed, the second sealing strip 7 can also abut against the window frame 2, thereby forming a second seal. This second seal further prevents rainwater from flowing into the room and at the same time prevents the hinge 3 from being eroded by rainwater. As Figure 4 shown in the figure, an extension portion 22 is provided on the third sealing strip 8. When the window sash 1 is closed, the third sealing strip 8 can abut against the window sash 1, thereby forming a third seal; the design of the extension portion 22 can increase the sealing area between the window frame 2 and the window sash 1, further improving the waterproof performance and sound insulation performance of the window structure.

[0044] As Figure 3 shown in the figure, a first drainage channel is provided on the lower profile of the window sash 1. This first drainage channel is located between the first sealing strip 6 and the second sealing strip 7. Specifically, a water collecting cavity is provided on the lower profile of the window sash 1. This water collecting cavity is communicated with the glass body installation cavity of the window sash 1 and is lower than the lower surface of the glass body. It is used to collect rainwater entering from the gap between the glass body and the glass body installation cavity. The water inlet end of the first drainage channel is communicated with the bottom of the water collecting cavity, and its water outlet end extends downwards and extends to the outside through the gap between the foaming portion 23 and the window frame 2; in specific implementation, water passing holes are provided on the corresponding profiles so that the profile cavities are communicated through the water passing holes, thereby forming this first drainage channel.

[0045] In addition, a second drainage channel is provided on the lower profile of the window frame 2. The water inlet end of the second drainage channel is communicated with the first drainage channel, and its water outlet end extends to the outside. Similarly, the profile cavities of the lower profile of the window frame 2 are also communicated through water passing holes, thereby forming the second drainage channel.

[0046] In this embodiment, the double drainage channel design can improve the drainage speed and prevent waterlogging. In addition, the water inlet end of the first drainage channel is lower than the lower surface of the glass body, so that rainwater can be effectively prevented from flowing into the room from the lower end of the glass body.

[0047] As an optional implementation manner of this embodiment, as Figure 1 shown in the figure, an outer rib 11 is provided on the side of the window frame 2 facing the outside and an inner rib 10 is provided inside the outer rib 11. The double rib design can increase the wind resistance strength of the window structure.

[0048] As an alternative implementation of this embodiment, a concealed lock is installed between the window sash 1 and the window frame 2. This concealed lock is a common lock in the door and window structure, and its specific structure and installation method will not be elaborated here. By installing the concealed lock, the width of the window frame 2 can be made narrower, improving the aesthetics.

[0049] As an alternative implementation of this embodiment, a screen sash 13 is also installed on the window frame 2, and the screen sash 13 is located on the side closer to the interior.

[0051] During installation, the buckle portion 17 is snapped into the pressing strip slot 16, and at this time, the abutting portion 18 abuts against the side surface of the outer groove wall of the pressing strip slot 16, as Figure 5 shown; since the buckle portion 17 and the inner wall of the pressing strip slot 16 are respectively provided with cooperating hooks, and the abutting portion 18 abuts against the side surface of the outer groove wall of the pressing strip slot 16, the screen mesh pressing strip 15 is not easily separated from the screen sash frame 14, improving the installation firmness of the screen mesh pressing strip 15.

[0052] In addition, a screen mesh installation cavity is formed between the screen mesh pressing strip 15 and the screen sash frame 14, and the screen mesh 21 is installed in the screen mesh installation cavity. Specifically, as Figure 5 shown, a second pressing strip 20 and a first pressing strip 19 are respectively provided on the screen sash frame 14 and the screen mesh pressing strip 15. The second pressing strip 20 and the first pressing strip 19 are both located in the screen mesh installation cavity, and they are used to fix the screen mesh 21. Both the second pressing strip 20 and the first pressing strip 19 can be disassembled. During implementation, different types of screen meshes 21, such as high-transparency screen meshes and medium-transparency screen meshes, can be installed in the mesh installation cavity by replacing the first pressing strip 19 with different thicknesses. In addition, when the first pressing strip 19 is removed, a diamond mesh can also be installed in the mesh installation cavity using screws.

[0053] Similarly, a concealed lock can also be installed between the screen sash 13 and the window frame 2 to reduce the width of the screen sash frame 14.
