Description

Technical Field

[0001] The utility model relates to the field of windows, in particular to a new type of sliding window profile capable of preventing rainwater from flowing back. Background Art

[0002] Sliding windows are windows with multiple sashes that can move parallel to the window frame. The window frame is machined with tracks to support the sashes. These tracks will affect the drainage of rainwater. The traditional way is to machine through holes on the profile to allow water to flow into the profile, and set an inclined guide plate in the profile. Finally, a drainage hole is machined on the side wall of the window frame at the lower end of the guide plate, and the rainwater flows out through the window frame profile. Figure 1 However, in order to ensure the integrity of the profile shape, the drainage holes can only be set at both ends of the window frame, which also limits the drainage speed and leads to the problem of poor drainage. At the same time, this structure easily causes impurities that fall on the through holes to settle in the window frame, and even provides a living place for insects. In windy weather, the drainage holes have a large space inside the window frame. When wind passes through the drainage holes, due to the inconsistent internal and external pressures, water backflow is easy to occur, and wind whistles are easy to be produced. Utility Model Content

[0003] The purpose of the utility model is to solve the problems in the background technology and provide a new sliding window profile that can prevent rainwater from backflowing. The sliding window profile can provide drainage speed while ensuring the stability of the window frame structure through structural improvement. At the same time, the added windproof strips can avoid water backflow and wind whistling.

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

[0005] A new sliding window profile capable of preventing rainwater from flowing back comprises an inner frame, an outer frame, a broken bridge and a sash frame, the inner frame being connected to an outer shell by the broken bridge, the sash frame being respectively mounted on the inner frame and the outer frame, the inner frame being in an outwardly convex step-shaped shape, and the step surface of the inner frame being inclined, the outer frame being in a mouth-shaped shape, the upper surface of the outer frame being coplanar with the inclined step surface of the inner frame, the step surface being processed with an upwardly extending Y-shaped stay, a track cover plate for limiting the sash frame being mounted on the Y-shaped stay, a first brush strip being mounted on the top side wall of the inner frame on one side of the track cover plate, the first brush strip being in contact with the surface of the track cover plate, a second brush strip being mounted on the bottom of the track cover plate close to one end of the outer frame, a supporting profile being mounted on the outer frame, the second brush strip being in contact with the surface of the supporting profile, a plurality of drainage holes being processed on the Y-shaped stay and the bottom of the supporting profile along the length direction, and a windproof strip being mounted on the bottom of the supporting profile close to the outdoor side.

[0006] The track cover is detachable, and a plug-in profile matching with the Y-shaped stay is processed on the middle of the bottom surface of the track cover.

[0007] The novel sliding window profile capable of preventing rainwater from flowing back provided by the utility model has the following beneficial effects:

[0008] (1) By arranging Y-shaped stays and supporting profiles on the inner frame and the outer frame, multiple drainage holes can be processed, thereby improving the drainage effect of the window. At the same time, the windproof strips can prevent water backflow and wind whistling;

[0009] (2) The first brush strip and the second brush strip can prevent insects from entering the window frame profile, thereby effectively improving the anti-mosquito effect of the sliding window;

[0010] (3) By providing a detachable track cover, the inside of the window frame can be cleaned when cleaning the window frame to ensure the normal use of the drainage function of the window frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Example

[0017] like Figure 2As shown, the new sliding window profile capable of preventing rainwater from flowing back provided by the present embodiment comprises an inner frame 1, an outer frame 2, a broken bridge 3 and a sash frame 4, the inner frame 1 is connected to the outer shell by the broken bridge 3, the sash frame 4 can be installed on the inner frame 1 and the outer frame 2 respectively, the inner frame 1 is in an outwardly convex step-shaped, and the step surface 5 of the inner frame 1 is inclined, the outer frame 2 is in a mouth-shaped, and the upper surface of the outer frame 2 is coplanar with the inclined step surface 5 of the inner frame 1, the purpose of which is to ensure the smoothness of drainage, the step surface 5 is processed with an upwardly extending Y-shaped stay 6, and a track cover 7 for limiting the sash frame 4 is installed on the Y-shaped stay 6, and rainwater can flow out through the gap between the track cover 7 and the inner frame 1, thereby reducing the punching operation and improving the production efficiency, the track on the track cover 7 and the load-bearing part of the Y-shaped stay 6 are located in the same vertical plane to improve the support stability of the sash frame 4, and a first brush strip 8 is installed on the top side wall of the inner frame 1 on one side of the track cover 7. A second brush strip 9 is installed at the bottom of one end of the plate 7 close to the outer frame 2, and the outer frame 2 is processed with a supporting profile 10 extending upward, and the track on the supporting profile 10 and the load-bearing part of the supporting profile 10 are located in the same vertical plane to improve the supporting stability of the sash frame 4, the second brush strip 9 is in contact with the surface of the supporting profile 10, and the first brush strip 8 and the second brush strip 9 are in contact with the surface of the track cover plate 7 to prevent impurities and insects from entering the profile, and the Y-shaped support bar 6 and the bottom of the supporting profile 10 are processed with a plurality of drainage holes 11 along the length direction, and a windproof strip 12 is installed at the bottom of the supporting profile 10 close to the outdoor side, and the protruding end of the windproof strip 12 is in contact with the outer frame 2, and the windproof strip 12 can prevent wind from blowing directly to the drainage hole 11, resulting in water backflow and wind whistling sound, and at the same time can also block the drainage hole 11 to prevent the drainage hole 11 from leaking out and affecting the beauty of the window.
