Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a waterproof material for sealing doors and windows. Background Technology
[0002] Door and window sealing refers to the process of using various materials and technologies to ensure a tight contact between the door / window and the frame when closed, thereby preventing air, moisture, noise, and dust from seeping in or out through gaps. Good door and window sealing not only improves the energy efficiency of buildings but also enhances living comfort and safety.
[0003] Existing door and window sealing methods typically involve sealing the gap between the window frame and the window through a weatherstripping on the window frame. However, as doors and windows are opened and closed repeatedly, the weatherstripping wears down, resulting in poor sealing performance. This allows rainwater to enter the room through the gap between the window frame and the window, which is quite inconvenient.
[0004] Therefore, it is necessary to design a waterproof sealing material for doors and windows that can seal the gap between the window frame and the window to prevent rainwater from entering the room through the gap between the window frame and the window, thereby improving the sealing effect. Utility Model Content
[0005] To overcome the shortcomings of existing door and window seals, where repeated opening and closing of doors and windows causes wear on the sealing strips, resulting in poor sealing performance and allowing rainwater to enter the room through the gap between the window frame and the window, this utility model provides a waterproof door and window sealing material that can seal the gap between the window frame and the window, preventing rainwater from entering the room through the gap and improving the sealing effect.
[0006] A waterproof material for sealing doors and windows includes a window frame, windows, sliding rails, a water-absorbing plate, and a sealing component. The upper and lower inner sides of the window frame are each connected to two sliding rails, and the left and right windows are slidably connected between the sliding rails. The lower rear side of the window frame is connected to a water-absorbing plate, and the window frame is equipped with a sealing component that can seal the windows.
[0007] To further clarify, the water intake plate has an inclined structure.
[0008] To further explain, the sealing assembly includes a suction fan, an air supply pipe, a first air bag, a second air bag, a hollow connecting block, a third air bag, and a latch. Two suction fans are connected to the lower front side of the window frame, and an air supply pipe is connected to the rear side of each suction fan. A first air bag is connected to each air supply pipe, and each first air bag is connected to the window frame and contacts its adjacent window. Second air bags are connected to the upper and lower parts of the window, and each second air bag is located between its adjacent sliding rails. Hollow connecting blocks are connected to the left and right sides of each second air bag, and each hollow connecting block is connected to its adjacent first air bag. A third air bag is connected to the inner side of the middle of each first air bag, and a latch is connected to the middle of each first air bag. Each third air bag is located in front of its adjacent latch, and the latch engages with its adjacent window. The third air bag contacts its adjacent window.
[0009] To further explain, it also includes a filter screen; a filter screen is connected to the front of the suction fan.
[0010] To further explain, it also includes window gap isolation plates and rollers. Two window gap isolation plates are placed between the first inflatable bags, and each window gap isolation plate is in contact with its adjacent window. Rollers are rotatably connected to the upper and lower parts of the window gap isolation plates, and the rollers are rotatably and slidably connected to the adjacent windows.
[0011] To further clarify, there is a drainage outlet at the lower rear of the window frame.
[0012] The beneficial effects of this utility model are as follows: 1. When the suction fan is activated, air enters the first air bag, the second air bag, the hollow connecting block and the third air bag, which seals the window frame and the window. The third air bag also seals and reinforces the bolt and the window, thus achieving a seal between the window frame and the window, preventing rainwater from entering the room through the gaps between the window frame and the window, and improving the sealing effect.
[0013] 2. This utility model moves and unfolds the window gap isolation plate, driving the rollers to rotate, so that the window gap isolation plate is located between the windows, achieving the effect of sealing and blocking the gap between the windows and preventing rainwater from entering through the gap between the windows.

Detailed Implementation
[0021] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0022] A waterproof material for sealing doors and windows, such as Figures 1-6As shown, the system includes a window frame 1, a window 2, a filter screen 3, a suction fan 4, an air supply pipe 5, a first air bag 6, a second air bag 7, a hollow connecting block 8, a third air bag 9, a latch 10, a window gap isolation plate 11, rollers 12, sliding rails 13, and a water guide plate 15. The upper and lower inner sides of the window frame 1 are each connected to two sliding rails 13, with left and right windows 2 slidably connected between the rails 13. The lower front of the window frame 1 is connected to two suction fans 4, each with a filter screen 3 connected to its front and an air supply pipe 5 connected to its rear. Each air supply pipe 5 is connected to a first air bag 6, which is connected to the window frame 1 and contacts its adjacent window 2. The upper and lower parts of each window 2 are connected to second air bags 7, which are located between their adjacent sliding rails 13. The second air bag 7 is connected to hollow connecting blocks 8 on both the left and right sides. The hollow connecting blocks 8 are connected to the adjacent first air bag 6. The inner side of the middle of the first air bag 6 is connected to the third air bag 9. The middle of the first air bag 6 is connected to the latch 10. The third air bag 9 is located in front of the adjacent latch 10. The latch 10 is engaged with the adjacent window 2. The third air bag 9 is in contact with the adjacent window 2. Two window gap isolation plates 11 are placed between the first air bags 6. The window gap isolation plates 11 are in contact with the adjacent window 2. The upper and lower parts of the window gap isolation plates 11 are rotatably connected to rollers 12. The rollers 12 are rotatably and slidably connected to the adjacent window 2. A drain outlet 14 is opened at the lower rear of the window frame 1. A water guide plate 15 is connected to the lower rear side of the window frame 1. The water guide plate 15 has an inclined structure for easy guidance.
[0023] When using this device, first install the window frame 1 on the wall with the water inlet plate 15 facing outwards. In rainy weather, the window 2 can be moved and closed on the sliding rail 13, engaging the latch 10 with the window 2, allowing the third air bag 9 to pass through the window 2. Then, start the suction fan 4, allowing air to pass through the filter 3 into the first air bag 6, the second air bag 7, the hollow connecting block 8, and the third air bag 9, causing them to inflate. The first and second air bags 6 and 7 seal the space between the window frame 1 and the window 2. The three inflatable bags 9 reinforce the seal between the latches 10 and the window 2, thereby sealing the gap between the window frame 1 and the window 2 and preventing rainwater from entering the room through the gap between the window frame 1 and the window 2, thus improving the sealing effect. Then, the window gap isolation plate 11 is moved and unfolded, driving the rollers 12 to rotate, so that the window gap isolation plate 11 is located between the windows 2, thereby sealing and blocking the gap between the windows 2 and preventing rainwater from entering through the gap between the windows 2. When rainwater enters the area below the window frame 1, it will be discharged through the drain outlet 14 and then guided by the water guide plate 15.
