Description

Waterproofing devices for doors and windows Technical Field

[0001] This utility model relates to the field of waterproofing technology for doors and windows, specifically a waterproofing device for doors and windows. Background Technology

[0002] Sliding doors and windows are a common type of door and window. They are opened and closed by installing tracks on the door and window frames, allowing the door and window sashes to slide left and right or up and down along the tracks. Sliding doors and windows are generally prone to water leakage. When it rains outside, rainwater can easily seep into the room through the gaps between the door and window frames and the window sashes. Some rainwater will also remain inside the door and window frames, forming water accumulation.

[0003] According to the search, the patent application with patent number 201920861448.0 discloses a dustproof, environmentally friendly and waterproof door and window, including a door and window frame, an inner window frame that is slidably connected to the lower two sides of the inside of the door and window frame, a horizontal bar that is horizontally set in the middle of the inside of the door and window frame, a positioning window that is fixedly installed on the upper two sides of the inside of the door and window frame, the inner window frame being located between the horizontal bar and the bottom of the door and window frame, and the width of the inner window frame being greater than half the width of the inside of the door and window frame, a horizontal groove plate that is horizontally set at the bottom of the inside of the door and window frame, and drainage holes that are evenly opened through the bottom outer wall of the door and window frame.

[0004] Although the dustproof, environmentally friendly, and waterproof doors and windows have a horizontal groove plate structure inside the door and window frame, and drainage holes are opened on the bottom outer wall of the door and window frame, so that when the door and window are closed, rainwater will fall into the bottom of the door and window frame, then flow out through the through holes in the horizontal groove plate and then through the drainage holes, the horizontal groove plate is installed in the door and window frame. When the window sash is pressed against the horizontal groove plate for a long time, it is easy for the horizontal groove plate to bend downward, which will cause the window sash to slide unsmoothly. In addition, the horizontal groove plate is set horizontally, and the water on its top surface flows through the through holes at a slower rate, resulting in poor drainage effect.

[0005] Therefore, we propose a waterproofing device for doors and windows. Summary of the Invention

[0006] In view of the shortcomings of the prior art, this utility model provides a waterproof device for doors and windows, which solves the problem that the horizontal groove plate of the window sash is prone to bending downward, which in turn causes the window sash to slide unsmoothly. In addition, the horizontal groove plate is set horizontally, and the water on its top surface flows through the through hole at a slow rate, resulting in poor drainage effect.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a waterproof device for doors and windows, including a door and window frame, wherein a groove is provided on the inner wall of the door and window frame;

[0008] A lower support plate with a right-angled triangular cross-section is fixedly installed on the inner wall of the bottom side of the groove. The top surface of the lower support plate is an inclined surface that slopes towards the outer facade. Drainage holes distributed in a linear array are opened at the bottom end of the outer facade of the door and window frame. The top surface of the lower support plate is provided with a vertically arranged first guide rail and a second guide rail. The side walls of the first guide rail and the second guide rail are respectively provided with a first through hole and a second through hole distributed in a linear array.

[0009] Preferably, the number and position of the first and second through holes correspond one-to-one with the drainage holes. The lower support plate, the first guide rail, and the second guide rail are integrally formed. Water entering the groove will flow along the top surface of the lower support plate to the side of the outer facade. During the flow, the water passes through the first and second through holes and is finally discharged through the drainage holes.

[0010] Preferably, the top surfaces of the first and second guide rails are fixedly equipped with U-shaped plates arranged in a linear array, and the inner walls of the U-shaped plates are rotatably mounted with rollers via shafts. The arrangement of the U-shaped plates and rollers facilitates the sliding of the window sash on the top of the first and second guide rails.

[0011] Preferably, an upper support plate of the same specifications as the lower support plate is fixedly installed on the inner wall of the top of the groove. The bottom surface of the upper support plate is an inclined surface that slopes towards the outer facade. A third guide rail and a fourth guide rail are fixedly installed on the bottom surface of the upper support plate. The third guide rail and the fourth guide rail correspond to the positions of the first guide rail and the second guide rail, respectively. The third guide rail and the fourth guide rail cooperate with the first guide rail and the second guide rail to facilitate the left and right translation of the window sash.

[0012] Preferably, elastic pads are adhered to both the front and rear sides of the inner wall of the groove. The elastic pads are made of rubber. By having the elastic pads contact the side wall of the window sash, the occurrence of rainwater entering the groove through the gap between the window sash and the groove can be reduced.

[0013] This utility model provides a waterproof device for doors and windows. It has the following beneficial effects:

[0014] 1. This waterproofing device for doors and windows supports the first and second guide rails via a lower support plate. The lower support plate is installed on the inner wall at the bottom of the groove and will not bend or deform, so that the window sash can slide smoothly on the first and second guide rails. Due to the right-angled triangle shape of the lower support plate and the setting of the first and second through holes, rainwater entering the groove will collect on the top surface of the lower support plate, and then flow outward along the top surface of the lower support plate. The rainwater passes through the first and second through holes in sequence and finally exits through the drainage hole, thereby preventing rainwater from entering the room and accumulating inside the groove. This helps to improve the rainwater drainage rate and solves the problems of existing devices where the window sash easily causes the horizontal groove plate to bend downward, resulting in poor sliding of the window sash. In addition, the horizontal groove plate is set horizontally, and the water on its top surface flows slowly through the through holes, resulting in poor drainage effect.

[0015] 2. This waterproof device for doors and windows uses two window sashes to be respectively attached to the first and third guide rails and the second and fourth guide rails. The window sashes are supported by rollers and can be easily slid left and right. The elastic pads contact the side walls of the window sashes, which can reduce the occurrence of rainwater entering the groove through the gap between the window sash and the groove.

[0023] As shown in Figures 1-4: The system includes a door / window frame 1. A groove 11 is formed on the inner wall of the door / window frame 1. A lower support plate 2 with a right-angled triangular cross-section is fixedly installed on the inner wall of the bottom side of the groove 11. The top surface of the lower support plate 2 is an inclined surface sloping towards the outer facade. Drainage holes 12 arranged in a linear array are formed at the bottom end of the outer facade of the door / window frame 1. A vertically arranged first guide rail 21 and second guide rail 22 are provided on the top surface of the lower support plate 2. First through holes 211 and second through holes 221 arranged in a linear array are respectively formed on the side walls of the first guide rail 21 and second guide rail 22. The number and position of the first through holes 211 and second through holes 221 correspond one-to-one with the drainage holes 12. The lower support plate 2, the first guide rail 21, and the second guide rail 22 are... The integrated design supports the first guide rail 21 and the second guide rail 22 via the lower support plate 2. The lower support plate 2 is installed on the inner wall of the bottom end of the groove 11 and will not bend or deform, so that the window sash can slide smoothly on the first guide rail 21 and the second guide rail 22. Due to the right-angled triangle shape of the lower support plate 2 and the setting of the first through hole 211 and the second through hole 221, rainwater entering the groove 11 will collect on the top surface of the lower support plate 2, and then the rainwater will flow outward along the top surface of the lower support plate 2. The rainwater passes through the first through hole 211 and the second through hole 221 in sequence, and finally is discharged through the drain hole 12, thereby preventing rainwater from entering the room and accumulating inside the groove 11, which helps to improve the rainwater drainage rate.

[0024] Example 2:

[0025] As shown in Figures 1-4: U-shaped plates 23 arranged in a linear array are fixedly installed on the top surfaces of both the first guide rail 21 and the second guide rail 22. Rollers 24 are rotatably mounted on the inner walls of the U-shaped plates 23 via shafts. An upper support plate 3 of the same specifications as the lower support plate 2 is fixedly installed on the inner wall of the top of the groove 11. The bottom surface of the upper support plate 3 is an inclined surface sloping towards the outer facade. A third guide rail 31 and a fourth guide rail 32 are fixedly installed on the bottom surface of the upper support plate 3.

Elastic pads 4 are bonded to both the front and rear sides of the inner wall of the groove 11. The elastic pads 4 are made of rubber. By attaching the two window sashes to the first guide rail 21 and the third guide rail 31, as well as the second guide rail 22 and the fourth guide rail 32, respectively, the window sashes are supported by rollers 24, which facilitates the left and right sliding of the window sashes. The contact between the elastic pads 4 and the side wall of the window sashes can reduce the occurrence of rainwater entering the groove 11 through the gap between the window sashes and the groove 11.

[0026] The working principle and usage process of this utility model: This waterproof device for doors and windows is used by installing the door and window frame 1 on the window opening in the wall, and then respectively attaching the two window sashes to the first guide rail 21, the third guide rail 31, the second guide rail 22, and the fourth guide rail 32. The window sashes are supported by rollers 24, which facilitates the left and right sliding of the window sashes. When it rains outside, the two window sashes are closed. If rainwater enters the interior of the groove 11 through the gap between the two window sashes, the rainwater will collect on the top surface of the lower support plate 2 and flow outward along the top surface of the lower support plate 2. The rainwater passes through the first through hole 211 and the second through hole 221 in sequence, and finally is discharged through the drain hole 12, thereby preventing rainwater from entering the room and accumulating inside the groove 11.
