Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy window frames, and more specifically, to aluminum alloy window frame profiles and their dustproof components. Background Technology

[0002] Aluminum alloy windows are window structures made of aluminum alloy profiles for the frame and sash. Due to their advantages of being lightweight and having high strength, aluminum alloy window frames can provide good support for walls and window sashes, making them widely used in modern buildings.

[0003] Most aluminum alloy window frames are made of aluminum alloy profiles. Existing aluminum alloy window frames include the profile body, which has a water collection cavity and a drainage hole. When it rains, the water collection cavity can collect rainwater on the window sash and window frame, while the drainage hole can drain the rainwater in the water collection cavity in a timely manner.

[0004] However, on non-rainy days, willow catkins, dust, and other debris in the air may be blown into the drain hole by the wind, causing it to become clogged.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide aluminum alloy window frame profiles and their dustproof components.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an aluminum alloy window frame profile, including a profile body, a water accumulation cavity is provided on the profile body, a drain hole communicating with the water accumulation cavity is provided on the side wall of the profile body, the cross-section of the drain hole is parallelogram, the bottom wall of the water accumulation cavity is inclined, and the lower bottom wall of the drain hole is in contact with the bottom wall of the water accumulation cavity.

[0008] A dustproof component includes a movable part and a dust-blocking part covering the drain outlet. The dust-blocking part is attached to the outer side wall of the profile body. The movable part includes a round rod housed in the drain hole and a floating plate disposed on the round rod. The floating plate can move the dust-blocking part as the water level rises, thus exposing the drain hole.

[0009] The present invention is further configured such that: the floating plate includes a first floating plate fixed to the end of the round rod away from the dust-blocking part and two second floating plates respectively symmetrically arranged on the outer wall of the round rod, wherein the side wall of the first floating plate near the round rod is in contact with the side wall of the water accumulation cavity.

[0010] The present invention is further configured such that: the round rod has a hollow cavity, the thickness of the first float and the second float are both less than the outer diameter of the round rod, and the upper wall of the first float is tangent to the outer peripheral wall of the round rod.

[0011] The present invention is further configured such that: a triangular block is provided on the outer peripheral wall of the round rod, and a card seat is provided on the dust-proof part for the round rod to be embedded in the end facing away from the first float, and a limiting groove is provided on the side wall of the card seat for the triangular block to be embedded in.

[0012] The present invention is further configured such that: the diagonal length of the drain hole is less than the width of the first float, and the sum of the widths of the two second floats and the diameter of the round rod is less than the width of the drain hole.

[0013] The present invention is further configured such that the round rod, the first float, and the second float are all made of PVC material.

[0014] In summary, this utility model has the following beneficial effects: When there is no water in the profile body, the round rod adheres to the bottom wall of the drainage hole under the action of gravity. At this time, the dust-blocking part covers the opening of the drainage hole on the outer wall of the profile body, making it difficult for debris in the outside air to enter the drainage hole, thereby reducing the possibility of the drainage hole being blocked by debris in the air. When it rains, the rainwater in the water accumulation chamber will flow into the drainage hole, and the floating plate will come into contact with the rainwater. The rainwater will generate a buoyancy on the floating plate, causing the floating plate to rise with the water level. The rising floating plate will drive the dust-blocking part to move together through the round rod, so that the opening of the drainage hole on the outer wall of the profile body is exposed, so that the rainwater can flow out of the profile body through the drainage hole, ensuring the drainage performance of the profile body in rainy weather.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1: Aluminum alloy window frame profiles, such as Figure 1As shown, the device includes a profile body 1, a water collection cavity 2, and a drain hole 3 connected to the water collection cavity 2 on the side wall of the profile body 1. The drain hole 3 has a parallelogram cross-section. The bottom wall of the water collection cavity 2 is inclined, and the lower bottom wall of the drain hole 3 fits against the bottom wall of the water collection cavity 2. The lowest point of the bottom wall of the water collection cavity 2 is close to the outer edge of the drain hole 3. During rainy weather, rainwater falling on the profile body 1 can collect in the water collection cavity 2. The inclined bottom wall of the water collection cavity 2 is formed by the rainwater in the water collection cavity 2 being drawn in by gravity. The water flows downwards towards the drain hole 3 and eventually flows out of the profile body 1 through the drain hole 3, allowing rainwater to be discharged from the profile body 1 more quickly. The bottom wall of the drain hole 3 is in contact with the bottom wall of the water accumulation chamber 2, making it difficult for rainwater to remain in the profile body 1, thus ensuring the drainage performance of the profile body 1. The outer surface of the profile body 1 is coated with an aluminum oxide coating, which can effectively separate the profile body 1 from the outside, effectively prevent the profile body 1 from being corroded, and effectively improve the service life of the profile body 1.

[0021] Example 2: Figures 2 to 3As shown, the dustproof component, used for installation in the drain hole 3 of Embodiment 1, includes a movable part and a dust-blocking part 4 for covering the drain outlet. The dust-blocking part 4 is attached to the outer wall of the profile body 1. The movable part includes a round rod 5 housed in the drain hole 3 and a floating plate disposed on the round rod 5. The round rod 5 and the dust-blocking part 4 are detachably connected. The floating plate can rise with the water level and drive the dust-blocking part 4 to move, exposing the drain hole 3. When there is no water in the profile body 1, the round rod 5 is attached to the bottom wall of the drain hole 3 under the action of gravity. At this time, the dust-blocking part 4 blocks the opening of the drainage hole 3 on the outer wall of the profile body 1, making it difficult for debris in the outside air to enter the drainage hole 3, thereby reducing the possibility of the drainage hole 3 being blocked by debris in the air. When it rains, the rainwater in the water accumulation chamber 2 will flow into the drainage hole 3, and the floating plate will come into contact with the rainwater. The rainwater will generate a buoyancy on the floating plate, causing the floating plate to rise with the water level. The rising floating plate will drive the dust-blocking part 4 to move together through the round rod 5, so that the opening of the drainage hole 3 on the outer wall of the profile body 1 is blocked. The opening is exposed, allowing rainwater to flow out of the profile body 1 through the drainage hole 3, ensuring the drainage performance of the profile body 1 in rainy weather. The floating plate includes a first floating plate 6 fixed to the end of the round rod 5 away from the dust-blocking part 4 and two second floating plates 7 respectively symmetrically arranged on the outer wall of the round rod 5. The first floating plate 6 is located in the water accumulation cavity 2. The arrangement of the first floating plate 6 and the second floating plate 7 can increase the contact area between the rainwater and the floating plate, so that the buoyancy provided by the rainwater can more easily drive the dust-blocking part 4 to rise. The side wall of the first floating plate 6 near the round rod 5 is in contact with the side wall of the water accumulation cavity 2. This arrangement allows the first floating plate 6 to play a certain limiting role for the dust-blocking part 4, so that the dust-blocking part 4 can fit better with the outer wall of the profile body 1, thus preventing the dust-blocking part 4 from entering the drainage hole 3. The round rod 5 has a closed hollow cavity 8. This arrangement allows the round rod 5 to have a larger surface area to contact the rainwater while keeping its mass constant, thereby obtaining more buoyancy and making it easier for the round rod 5 to overcome gravity and rise with the water level.

[0022] like Figure 2 and Figure 3As shown, the round rod 5, the first float 6, and the second float 7 are all made of PVC material. PVC material has a low density, making the round rod 5, the first float 6, and the second float 7 more likely to float in rainwater. This allows the movable part to easily move the dust-blocking part 4. The round rod 5 blank includes a rod material and a cover material. The hollow cavity 8 is formed in the rod material. After the rod material, the first float 6, and the second float 7 are injection molded and cooled, the cover material is directly adhered to the rod material while the cover material is still being injection molded and not yet cooled, thus fixing the cover material to the rod material. This production process... The process enhances the connection strength between the round rod 5 and the first float 6 and the second float 7. The thickness of both the first float 6 and the second float 7 is less than the outer diameter of the round rod 5. The upper wall of the first float 6 is tangent to the outer peripheral wall of the round rod 5. This arrangement ensures that when the round rod 5 is in contact with the lower bottom wall of the drain hole 3, there is a gap between the first float 6 and the bottom wall of the water accumulation chamber 2. When there is rainwater in the water accumulation chamber 2, the rainwater can contact the lower wall of the first float 6 through the gap, thus providing better buoyancy for the first float 6. A triangular block 9 is provided on the outer peripheral wall of the round rod 5. The cross-section of the triangular block 9 is a right triangle. The inclined surface of the 9 is located near the end of the round rod 5 facing away from the first float 6. The dustproof part 4 is provided with a retainer 10 for the end of the round rod 5 facing away from the first float 6 to be inserted. The dustproof part 4 and the retainer 10 are both made of PVC material and are injection molded as one piece. The retainer 10 is located near the lower part of the dustproof part 4. The side wall of the retainer 10 is provided with a limiting groove 11 for the triangular block 9 to be inserted. When the moving part or the dustproof part 4 is damaged due to long-term use, people can separate the moving part from the dustproof part 4 by pulling the triangular block 9 out of the limiting groove 11, which makes it easier for people to repair the damaged moving part or the dustproof part 4. The diagonal length of the drainage hole 3 is less than the width of the first float 6. This design makes it difficult for the first float 6 to enter the drainage hole 3 when it moves under the buoyancy of rainwater, so that the first float 6 can always slide on the side wall of the water accumulation cavity 2, ensuring the limiting effect of the first float 6 on the dust blocking part 4. The sum of the width of the two second floats 7 and the diameter of the round rod 5 is less than the width of the drainage hole 3. This design gives the second floats 7 and the round rod 5 a high degree of freedom in the drainage hole 3, so that the buoyancy provided by the rainwater can more easily drive the round rod 5 to move, facilitating the exposure of the opening of the drainage hole 3 on the outer wall of the profile body 1.
