Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, and in particular to a thermally broken aluminum alloy window slide rail with a drainage channel. Background Technology

[0002] Thermally broken aluminum alloy windows are widely used in various scenarios such as residential and commercial buildings due to their excellent thermal insulation performance and strong structural stability. As the core support component for the sliding of the window sash, the sliding track not only needs to bear the weight of the window sash and ensure smooth sliding, but also needs to have a reliable drainage function to deal with the problem of rainwater seeping into the gap between the sliding track and the frame during rainy weather.

[0003] Currently, most mainstream thermally broken aluminum alloy window tracks on the market employ a drainage structure with side cutouts at both ends of the track. The core idea behind this design is to allow rainwater seeping into the gaps between the track and the frame to flow naturally along the length of the track to the side cutouts at both ends, and then drain out to the outside through these cutouts. However, this traditional drainage method has significant drawbacks in practical applications: Firstly, rainwater must travel a long distance within the narrow gap to reach the drain outlet. The long flow path is affected by the frictional resistance of the inner wall of the gap, resulting in extremely low drainage efficiency. Especially during severe weather conditions such as short-term heavy rainfall or downpours, the amount of rainwater seeping in far exceeds the amount draining out, making it easy for rainwater to accumulate rapidly within the gap. Secondly, when rainwater accumulates to a certain height within the gap, it will break through the sealing gap between the track and the window sash, causing rainwater to overflow. Utility Model Content

[0004] The purpose of this invention is to provide a thermally broken aluminum alloy window slide rail with a drainage channel, which solves the problems of long drainage path and low efficiency that exist when the traditional slide rail uses side cuts at both ends of the track for drainage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A thermally broken aluminum alloy window sliding track with a drainage channel includes a frame made of thermally broken aluminum alloy, the top surface of which is constructed as an inclined surface, and the height of the inclined surface near the indoor side is higher than the height near the outdoor side. A slide rail is fixedly installed on the frame. The bottom of the slide rail is in contact with and fits against the inclined surface. The top of the slide rail is constructed as a continuous sliding track, which is used to accommodate the sliding of the window. At the position where the bottom of the slide rail contacts the inclined surface, a plurality of first drainage grooves are evenly provided along the length of the slide rail. The first drainage grooves are adapted to the inclination direction of the inclined surface and are used to drain rainwater between the slide rail and the inclined surface. The slide rail has a triangular cross-section that fits the inclined surface of the frame, providing support for the slide rail and the window.

[0006] Preferably, the top of the frame is provided with two side guards, which extend along the length of the frame and are located on both sides of the slide rail to restrict the window on the slide rail; of the two side guards, the side guard closer to the outside is defined as the outside side and the side guard closer to the inside is defined as the inside side.

[0007] Preferably, a plurality of second drainage channels are provided along the length of the outdoor edge frame. The structure of the second drainage channel is adapted to the first drainage channel to drain rainwater from the gap between the window and the outdoor edge. The second drainage channels and the first drainage channels are aligned and distributed along the length of the frame to prevent rainwater from accumulating in the gap between them.

[0008] Preferably, the frame has an integrally formed extension side on the side closest to the outside, and the extension side is flush with the inclined surface of the frame to form an eaves that guides rainwater; the top of the extension side receives rainwater discharged from the first drainage channel to prevent rainwater from contacting the gap between the frame and the wall.

[0009] Preferably, the frame, outdoor side, indoor side, extension side, and slide rail are all provided with an anti-corrosion coating on the frame surface, and the anti-corrosion coating is one of anodized layer, fluorocarbon spraying layer or powder spraying layer.

[0010] Preferably, the tops of adjacent slide rails distributed along the length of the frame are flush to offset the height difference of the corresponding frame inclined surfaces, so as to accommodate two windows of the same height.

[0011] This utility model has at least the following beneficial effects: By evenly distributing drainage channels along the length of the bottom of the slide rail, combined with the triangular cross-section design of the slide rail, on the one hand, the triangular structure utilizes the principle of geometric stability to ensure the support strength of the slide rail while creating a smooth flow space between the bottom of the slide rail and the inclined surface of the frame; on the other hand, the evenly distributed drainage channels can quickly intercept and directly drain rainwater from the gaps point by point, eliminating the need for it to flow a long distance along the track, significantly shortening the water flow path and reducing resistance. Moreover, the inclined surface at the top of the frame accelerates the flow of rainwater, fundamentally solving the problems of slow drainage and easy overflow in traditional structures, while taking into account both the structural strength and drainage performance of the slide rail.

[0017] Reference Figure 1-4A thermally broken aluminum alloy window sliding rail 3 with a drainage channel includes a frame 1 made of thermally broken aluminum alloy. The top surface of the frame 1 is constructed as an inclined surface 11, with the height of the inclined surface 11 near the interior being higher than that near the exterior. The inclination angle of the inclined surface 11 is set to 3°-8°, which ensures natural rainwater flow. The height of the inclined surface 11 near the interior is 10-15mm higher than that near the exterior, forming a natural drainage slope. A sliding rail 3 is fixedly installed on the frame 1. The bottom of the sliding rail 3 is in contact with and fits against the inclined surface 11. The top of the sliding rail 3 is constructed as a continuous sliding track 32, which is used to adapt to the sliding of the window 2. The top of the sliding rail 3 is precision machined to form a continuous sliding track 32, and the surface roughness of the sliding track 32 is controlled between Ra0.8 and Ra1. The thickness is 6μm, which is compatible with the roller 21 at the bottom of window 2, reducing sliding friction and making window 2 open and close more smoothly; at the position where the bottom of the slide rail 3 contacts the inclined surface 11, several first drainage grooves 31 are evenly opened along the length of the slide rail 3. The first drainage grooves 31 are adapted to the inclination direction of the inclined surface 11 and are used to drain rainwater between the slide rail 3 and the inclined surface 11. The extension direction of the first drainage grooves 31 is completely consistent with the inclination direction of the inclined surface 11. When rainwater seeps into the space between the slide rail 3 and the inclined surface 11, it will flow along the inclined surface 11 under the action of gravity and be quickly discharged through the first drainage grooves 31. The dimensions of the first drainage grooves are limited to: width of 8mm to 12mm, depth of 5mm to 8mm, and spacing between adjacent drainage grooves of 30mm to 50mm. The edges of the groove openings are rounded with a radius of 0.5mm to reduce rainwater residue. The slide rail 3 has a triangular cross-section structure 33, which fits into the inclined surface 11 of the frame 1 to provide support for the slide rail 3 and the window 2. Utilizing the principle of triangular stability, it provides uniform and stable support for the slide rail 3 and the window 2, and can withstand the weight of the window 2 and the impact force during sliding.

[0018] Furthermore, two side rails 14 are respectively constructed on the top of the frame 1. The side rails 14 extend along the length of the frame 1, and the two side rails 14 are located on both sides of the slide rail 3 to restrict the window 2 on the slide rail 32. Among the two side rails 14, the side rail 14 closer to the outside is defined as the outside side 141, and the side rail 14 closer to the inside is defined as the inside side 142.

[0019] Furthermore, the outdoor edge 141 is provided with a plurality of second drainage channels 1411 along the length of the frame 1. The structure of the second drainage channel 1411 is adapted to the first drainage channel 31. The second drainage channel and the first drainage channel are aligned along the vertical center line, and the width of the second drainage channel is 2mm-3mm wider than the first drainage channel to ensure that rainwater is completely collected without leakage. This is used to drain rainwater in the gap between the window 2 and the outdoor edge 141. The second drainage channel 1411 and the first drainage channel 31 are aligned and distributed along the length of the frame 1 to prevent rainwater from accumulating in the gap between them.

[0020] Furthermore, the side of the frame 1 closest to the outside is integrally formed with an extension edge 13, which is flush with the inclined surface 11 of the frame 1, forming an eaves that guides rainwater; the top of the extension edge 13 receives the rainwater discharged from the first drainage channel 31, preventing rainwater from contacting the gap between the frame 1 and the wall.

[0021] Furthermore, the frame 1, the outdoor side 141, the indoor side 142, the extension side 13, and the slide rail 3 are all provided with an anti-corrosion coating on the surface of the frame 1. The anti-corrosion coating is one of anodized layer, fluorocarbon spray layer or powder spray layer, and the thickness of the anti-corrosion coating is 60μm-80μm.

[0022] Furthermore, the tops of adjacent slide rails 3 distributed along the length of frame 1 are aligned to offset the height difference of the corresponding inclined surfaces 11 of frame 1, so as to accommodate two windows 2 of the same height.

[0023] In summary, traditional side-cut designs require rainwater to flow along the length of the gap between the track and frame 1 to the two end cuts for discharge. This not only results in a long water flow path and high resistance, leading to extremely low drainage efficiency, but also makes it prone to overflowing and seeping into the interior or corroding components during short-term heavy rainfall. In contrast, this solution uses drainage channels evenly distributed along the length of the bottom of the slide rail 3, combined with the triangular cross-section design of the slide rail 3. On the one hand, the triangular structure utilizes the principle of geometric stability to ensure the support strength of the slide rail 3 while creating a smooth flow space between the bottom of the slide rail 3 and the inclined surface 11 of the frame 1. On the other hand, the evenly distributed drainage channels can quickly intercept and directly discharge rainwater in the gap, eliminating the need for long-distance flow along the track. This significantly shortens the water flow path and reduces resistance, fundamentally solving the problems of slow drainage and easy overflow in traditional structures, while also taking into account the structural strength and drainage performance of the slide rail 3.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
