Description

Technical Field

[0001] The utility model relates to the field of windows, in particular to a sliding window profile capable of improving sealing performance. Background Art

[0002] Sliding windows are windows with multiple sashes that can move parallel to the window frame. The window frame will be machined with tracks to support the sashes. These tracks will affect the drainage of rainwater. The traditional way is to machine drainage holes at the bottom of the tracks and use the drainage holes to drain the rainwater. Figure 1 As shown, however, the height difference between the profile height and the track height of this structure is small, and rainwater can easily flow back into the room in extreme weather. There is only contact between the track and the window sash through the wheels, and the sealing is poor, which can easily cause wind whistling. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the background technology and provide a sliding window profile that can improve the sealing performance. The sliding window profile increases the indoor height by adding a handrail frame indoors, effectively avoiding rainwater backflow, and at the same time improves the sealing performance of the window by improving the track.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A sliding window profile capable of improving sealing performance comprises an inner frame, an outer frame, a thermal break bridge, a sash frame and a handrail frame, wherein the inner frame is connected to the outer frame by the thermal break bridge, the surface of the inner frame is inclined, a Y-shaped stay is processed on the inner frame, a cover plate for supporting the sash frame is installed on the Y-shaped stay, a track overlapping with the Y-shaped stay is installed on the cover plate, the surface of the outer frame is coplanar with the surface of the inner frame, an upwardly extending supporting profile is processed on the outer frame, a track is installed on the supporting profile, the sash frame is movably installed on the track, a plurality of drainage holes are processed on the bottom of the Y-shaped stay and the supporting profile along the length direction, a windproof strip abutting against the outer frame is provided on the bottom of the supporting profile close to the outdoor side, the handrail frame is installed on the side wall of the inner frame close to the indoor side, and the height of the handrail frame is adapted to the profile height of the sash frame.

[0006] The cover plate is detachably mounted on the Y-shaped support bar, and brush strips extending outward are provided at the bottom of both sides of the cover plate. The brush strips between adjacent cover plates are abutted against each other, an insertion strip extending into between adjacent brush strips is provided at the bottom of one side of the fan frame, and a strip in contact with the cover plate is provided at the bottom of the other side.

[0007] The utility model provides a sliding window profile capable of improving sealing performance, which has the following beneficial effects:

[0008] (1) By processing drainage holes at the bottom of the Y-shaped support bar and the supporting profile, and setting windproof strips on the supporting profile, it is possible to prevent wind from blowing directly into the drainage holes, causing water backflow and wind whistling. At the same time, the cover plate on the Y-shaped support bar can separate a space for rainwater to flow out and balance the pressure caused by wind, further preventing rainwater backflow. In combination with the handrail frame, safety can be guaranteed even in extreme weather;

[0009] (2) By installing brush strips on the cover plate, the brush strips abutting against each other can prevent impurities from entering the drainage space. At the same time, the cover plate is detachable, and when cleaning the window frame, the inside of the window frame can be cleaned, ensuring that the drainage function of the window frame can be used normally, while increasing the sealing of the window frame;

[0010] (3) By arranging inserts and wool strips on the fan frame, the sealing performance of the fan frame can be improved, and the whistling sound when wind passes through the fan frame can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example

[0017] like Figure 2As shown, the sliding window profile that can improve the sealing performance provided by this embodiment includes an inner frame, an outer frame, a broken bridge, a sash frame and a handrail frame, the inner frame is connected to the outer frame by the broken bridge, the surface of the inner frame is inclined, a Y-shaped support bar is processed on the inner frame, a cover plate supporting the sash frame is installed on the Y-shaped support bar, a track overlapping with the Y-shaped support bar is installed on the cover plate, the surface of the outer frame is coplanar with the surface of the inner frame, and the coplanarity can improve the smoothness of rainwater, an upwardly extending support profile is processed on the outer frame, a track is installed on the support profile, and the sash frame is movably installed on the track, so The bottom of the Y-shaped stay and the supporting profile are processed with multiple drainage holes along the length direction. Multiple drainage holes can increase the drainage speed. The bottom of the supporting profile close to the outdoor side is provided with a windproof strip connected to the outer frame. On the one hand, the windproof strip can prevent wind from blowing directly into the drainage holes to produce backflow and wind whistling sounds. On the other hand, it can block the drainage holes that leak out to ensure the beauty of the window. The handrail frame is installed on the side wall of the inner frame close to the indoor side. The height of the handrail frame is adapted to the profile height of the sash frame, so that even in extreme weather, rainwater will find it difficult to overflow the handrail frame and flow into the room.

[0018] In order to improve the airtightness between the sash frame and the window frame, Figure 3 As shown, the cover plate is detachably mounted on the Y-shaped support bar, and brush strips extending outward are provided at the bottom of both sides of the cover plate. The brush strips between adjacent cover plates are abutted against each other, and brush strips of the same height as adjacent cover plates are installed on the inner frame and the supporting profile. The brush strips can prevent impurities from entering the window frame and can also improve the sealing of the drainage structure. An insertion strip extending between adjacent brush strips is provided at the bottom of one side of the sash frame, and a wool strip in contact with the cover plate is provided at the bottom of the other side. A sealing area can be formed at the bottom of the sash frame through the insertion strip and the wool strip, thereby avoiding the whistling sound caused by wind blowing.
