[0031] like Figure 1-Figure 4 As shown, a casement window structure in one embodiment of the utility model comprises a frame 1, a window sash 2 and a plurality of sealing strips; the window sash 2 is connected to the frame 1 via a hinge 3, the frame 1 is provided with a plurality of step portions, so that the cross-section of the frame 1 is stepped, and the sealing strips are sequentially arranged in the gaps between the step portions and the window sash 2; wherein the size of the gap between the step portions and the window sash 2 is within the sealing range of the sealing strips; wherein the sealing strips close to the indoor side are installed on the frame 1, and the sealing strips close to the outdoor side are installed on the window sash 2.

[0032] The casement window structure adopts a stepped frame 1 design, and the sealing strips are sequentially arranged at the gap positions between the step portion and the window sash 2, thereby realizing multiple sealing of the casement window structure, making the frame 1 drain more smoothly, more effectively blocking rainwater and typhoons from entering the room, and greatly improving the water tightness and air tightness of the window; the hinge 3 is installed on the lowest step, and when the window sash 2 is opened, the hinge 3 will not scratch the sealing strip when it undergoes cross-stretching movement, and can be quickly replaced and repaired; in addition, the step portion and the window sash 2 are provided to form multiple gaps, and the sizes of the gaps are all within the blocking range of the sealing strips, so that the window sash 2 and the frame 1 can be sealed with the same size of sealing strips, reducing production costs and realizing sealing strips in the same casement window. Multiple sealing can be achieved with only one specification of sealing strips, saving the trouble of duckbill clamp mold opening and reducing the pressure on the inventory of sealing strips; and solving the problem that the existing casement window sealing strips have multiple shapes and high maintenance and replacement costs.

[0033] In one embodiment, a fixing groove is provided on the window sash 2 or the frame 1, and the sealing strip is fixed in the fixing groove. The sealing strip is embedded in the fixing groove, which can be quickly replaced and repaired.

[0034] Specifically, there are three sealing strips, the first sealing strip 4 is installed on the window sash 2 through a fixing groove, and the second sealing strip 5 and the third sealing strip are installed on the frame 1 through a fixing groove.

[0035] In one embodiment, the fixing groove is a hollow groove with a convex U-shaped cross-section, and both sides of the convex opening are beveled edges to facilitate the embedding and fixing of the sealing strip.

[0036] In one embodiment, the sealing strip includes a convex ridge 41 for being embedded in the fixing groove and a filling portion 42 for blocking the gap between the frame 1 and the window sash 2; the filling portion 42 is arranged in an arc shape. The surface of the filling portion 42 and the sealing gap is arranged in an arc surface, and the smooth transition of the arc surface can improve the water blocking and drainage effect of the sealing strip, and further prevent rainwater from entering the airtight cavity; in addition, it can avoid the problems of flanging and difficult corner connection caused by straight strips, and the structure is more stable, without flanging, easy corner connection, and effectively improve the watertight and airtight performance.

[0037] Specifically, the indoor side wall of the window sash 2 is flush with the indoor side wall of the step portion.

[0038] Specifically, the first sealing strip 4 is located on the outdoor side, and when locked, the first sealing strip 4 overlaps with the step portion on the outdoor side; the second sealing strip 5 is arranged on the frame 1, and when locked, the second sealing strip 5 overlaps with the protrusion of the window sash 2; the third sealing strip is arranged on the step portion on the indoor side, and when locked, the third sealing strip overlaps with the protrusion of the window sash 2.

[0039] The third sealing strip is connected to the step portion on the indoor side and extends to the outdoor side and overlaps the window sash 2.

[0040] Specifically, in the vertical direction, the first sealing strip 4 , the second sealing strip 5 and the third sealing strip are arranged in sequence from bottom to top.

[0041] Among them, the horizontal heights of the multiple step portions gradually increase from the outdoor side to the indoor side, and the step portion on the outdoor side plays a role in blocking rainwater to prevent rainwater from splashing into the room; in addition, the profile of the fixed groove set on the window sash 2 extends downward to form a water-blocking portion 21 for blocking rainwater, which more effectively blocks rainwater and typhoons from entering the room, greatly improving the water tightness and air tightness of the window.

[0042] Specifically, one end of the hinge 3 is connected to the step portion on the outdoor side and the other end is connected to the window sash 2 .

[0043] In one embodiment, the first sealing strip 4, the hinge 3, the second sealing strip 5 and the third sealing strip are arranged in sequence from the outdoor side to the indoor side.

[0044] Among them, the hinge 3 is installed on the step portion on the outdoor side and is located between the first sealing strip 4 and the second sealing strip, and the first sealing strip 4 is installed on the window sash 2 through a fixing groove. When the window sash 2 is opened, the hinge 3 performs a cross-stretching movement and will not scratch the first sealing strip 4 installed on the window sash 2. The second sealing strip 5 is located on the middle step portion and is installed on the frame 1 through a fixing groove. Therefore, when closed, the second sealing strip 5 provides further sealing for the casement window.

[0045] Specifically, the casement window structure also includes a window frame 6, and the frame 1 is installed on the window frame 6; a first thermal insulation strip 7 is provided between the indoor side and the outdoor side of the window sash 2 and between the indoor side and the outdoor side of the frame 1; a second thermal insulation strip 7 is provided between the indoor side and the outdoor side of the window frame 6; the size of the second thermal insulation strip 7 is larger than the size of the second thermal insulation strip 7.

[0046] In one embodiment, the outdoor side of the window frame 6 is flush with the outdoor side of the window sash 2 .

[0047] Among them, the frame 1 is buckled into the window frame 6. When pursuing better thermal insulation performance and choosing larger glass, and thus requiring a larger glass notch, this requirement can be met by replacing the thermal insulation strip 7. However, the duckbill strips need to be re-matched, so that the factory needs to add another variety of duckbill strips. In addition to the cost of re-molding, additional procurement time is required. However, when the size of the first thermal insulation strip 7 is the same, when the first thermal insulation strips 7 of different sizes are replaced, the gap formed by the window sash 2 and the frame 1 remains unchanged. Therefore, the sealing strip only needs one specification to meet the sealing requirements, avoiding the operation of re-matching the duckbill strips, saving time, labor and money.

[0048] On the other hand, when the size of the second thermal insulation strip 7 is larger than the size of the second thermal insulation strip 7, the width of the frame 1 is smaller than the width of the window frame 6, which is convenient for snapping the frame 1 onto the window frame 6; the outdoor side of the window frame 6 is flush with the outdoor side of the window sash 2, which is convenient for maintaining the beauty of the casement window.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
