Abstract
Description
Technical Field
[0001] This utility model relates to the field of window technology, specifically a window sill structure with built-in concealed row. Background Technology
[0002] In modern building window and door systems, window sills not only serve a decorative and aesthetic purpose but are also a crucial component of the window and door drainage system. Traditional window sills typically employ an exposed drainage design, where visible drainage holes or covers are installed on the surface or outer edge of the window sill to facilitate timely rainwater drainage. However, while this exposed drainage structure improves drainage efficiency, it inevitably exposes the drainage components, affecting the overall aesthetics of the facade. This is particularly problematic in high-end residential buildings and commercial complexes where a pleasing architectural appearance is paramount.
[0003] To address these issues, some manufacturers have attempted to adopt concealed drainage structures, which conceal the drainage path by setting drainage channels inside the profiles, thereby improving the visual effect. However, such concealed drainage structures usually require redesigning special profiles, which are complex in structure and require high processing precision, leading to a significant increase in profile costs and increasing the difficulty of product development and manufacturing. In addition, traditional window sashes often use single or double sealing structures at the opening position, which have limited waterproof performance and still pose a risk of rainwater seepage under strong winds and rain. Utility Model Content
[0004] This utility model provides a window sill structure with built-in concealed row, which can effectively solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a window sill structure with a built-in concealed drain, comprising an inner frame, a window sill cover plate embedded and installed at the top of the side end of the inner frame, and a water-blocking plate rotatably installed at the bottom end of the window sill cover plate.
[0006] A window sill is installed at the bottom of the side of the inner frame, and several drainage outlets are provided on the side end face of the window sill cover and the bottom face of the window sill cover of the inner frame.
[0007] According to the above technical solution, the water-retaining plate is L-shaped with a cylindrical top, and is embedded and rotatedly installed at the bottom of the window sill cover.
[0008] According to the above technical solution, the outer side of the inner frame is connected to the outer frame by a rubber sealing strip, and the rubber sealing strip between the inner frame and the outer frame is embedded.
[0009] According to the above technical solution, the bottom edge of the window sill cover is embedded and installed on the side of the inner frame by a fastening strip, and the shape of the bottom edge of the window sill cover is the same as the shape of the fastening strip.
[0010] According to the above technical solution, the windowsill is connected to the inner frame by fixing screws, and a sealing strip is embedded in the horizontal surface of the inner frame on the side of the fixing screws.
[0011] According to the above technical solution, the number of drainage outlets in the inner frame and the window sill cover is the same.
[0012] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.
[0013] More aesthetically pleasing: By optimizing the structure, the exposed drainage function is concealed, eliminating the traditional exposed drainage cover, resulting in a cleaner visual effect and improving the overall building facade quality;
[0014] Reduce profile costs: There is no need to design special concealed profiles; the concealed effect can be achieved by using standard exposed profiles, which significantly reduces material development and manufacturing costs.
[0015] Enhanced waterproofing: The window sash opening area features a triple-seal design, effectively improving the overall waterproofing capability of the door and window system, making it suitable for applications with strong winds and rain or high airtightness requirements.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] Example: Figure 1-11 As shown, this utility model provides a technical solution: a window sill structure with a built-in concealed drain, including an inner frame 2. The outer side of the inner frame 2 is connected to the outer frame 1 by a rubber sealing strip, and the rubber sealing strip between the inner frame 2 and the outer frame 1 is embedded. The bottom edge of the window sill cover 3 is embedded and installed on the side of the inner frame 2 by a fastening strip 5, and the shape of the bottom edge of the window sill cover 3 is the same as the shape of the fastening strip 5, which can facilitate the overall installation and adjustment. The top of the side of the inner frame 2 is embedded and installed with the window sill cover 3, and the bottom of the window sill cover 3 is rotatably embedded and installed with a water-blocking plate 7.
[0032] A window sill plate 8 is installed at the bottom of the side of the inner frame 2. Several drainage holes 9 are opened on the side end face of the inner frame 2 and the bottom face of the window sill cover plate 3. The number of drainage holes 9 of the inner frame 2 and the window sill cover plate 3 is the same, which can improve the drainage rate.
[0033] To facilitate drainage, the water-blocking plate 7 is L-shaped with a cylindrical top, and is embedded and rotated at the bottom of the window sill cover plate 3.
[0034] The windowsill 8 is connected to the inner frame 2 by fixing screws 6. A sealing strip 4 is embedded in the horizontal side of the inner frame 2 at the fixing screw 6 to improve the sealing performance.
[0035] The working principle and usage process of this utility model are as follows: The windowsill plate 8 is connected to the inner frame 2 by fixing screws 6. Then, the windowsill cover plate 3 is inserted into the inner frame 2. When there is rain, the rainwater on the side of the inner frame 2 is discharged into the drain 9 at the bottom of the windowsill cover plate 3 through the drain hole 9 on its surface. At this time, the rainwater will hit the water-blocking plate 7, thereby rotating the water-blocking plate 7 and draining normally. When there is no water, the water-blocking plate 7 is reset to complete the sealing operation and prevent backflow.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
