DETAILED DESCRIPTION

[0018] The following is combined with Figure 1 The utility model is described in further detail.

[0019] refer to Figure 1 A door and window structure for preventing water seepage includes a door and window profile 1, and a mounting groove 2 is arranged inside the door and window profile 1 for fixing and installing glass. In order to enhance the waterproof performance, a sealing strip 3 is arranged on the side of the mounting groove 2 close to the outside. The sealing strip 3 fits the contour of the mounting groove 2 and is installed on the inner wall of the mounting groove 2 through a connecting piece 4.

[0020] A water-swellable waterstop strip 5 is also provided inside the installation groove 2 . The water-swellable waterstop strip 5 is located below the sealing strip 3 . The water-swellable waterstop strip 5 is connected to the bottom wall of the sealing strip 3 via an adhesive layer 6 .

[0021] In order to ensure that the connection between the water-swellable waterstop strip 5 and the sealing strip 3 is more firm and reliable, a plurality of screws 16 are also provided on the water-swellable waterstop strip 5, and the plurality of screws 16 are evenly distributed along the length direction of the sealing strip 3. These screws 16 pass through one end of the water-swellable waterstop strip 5 and are threadedly connected to the sealing strip 3, ensuring a tight connection and long-term stability between the two, and also preventing the adhesive layer 6 from failing after long-term use, resulting in the water-swellable waterstop strip 5 and the sealing strip 3 falling off.

[0022] Once the water-swellable waterstop strip 5 comes into contact with water, it will expand rapidly to fill up any tiny gaps that may exist, thereby effectively preventing the infiltration of water.

[0023] On the side of the installation groove 2 close to the outdoors, a rain shield strip 7 is correspondingly arranged on the top wall of the sealing strip 3, and the rain shield strip 7 extends out of the installation groove 2. A blocking strip 8 is arranged on the side where the rain shield strip 7 extends out of the installation groove 2, and the bottom wall of the blocking strip 8 is in contact with the bottom wall of the installation groove 2 to reduce the possibility of rainwater seeping through the gap between the rain shield strip 7 and the groove wall of the installation groove 2. In order to further enhance the waterproof effect, an extension strip 9 is provided at the end of the blocking strip 8.

[0024] In order to further enhance the waterproof performance, the rain-proof strip 7 and the blocking strip 8 are both provided with a rain-facing slope 10, which is inclined toward the outdoor side, so that when rain falls on the rain-proof strip 7, the rain can flow down smoothly and will not accumulate on the doors and windows. The planes where the two rain-facing slopes 10 are located are coplanar, ensuring the overall aesthetics and practicality.

[0025] On the side of the sealing strip 3 close to the glass, a plurality of cams 11 are arranged, and the plurality of cams 11 are evenly distributed along the height direction of the sealing strip 3. These cams 11 are in close contact with the side wall of the glass, which not only enhances the stability of the sealing strip 3, but also helps to improve the waterproof performance.

[0026] In order to facilitate installation and removal of the sealing strip 3, a groove 12 is provided on the groove wall of the installation groove 2. The connecting member 4 includes inserting strips 13 provided on the sealing strip 3, which can be conveniently inserted into the groove 12 to achieve rapid installation and removal of the sealing strip 3.

[0027] A guide arc surface 14 is also provided on one side of the notch of the installation groove 2. This design not only improves the aesthetics of the door and window, but also helps to guide the insertion strip 13 to be smoothly inserted into the embedding groove 12. At the same time, an extrusion slope 15 is provided at the corners of the insertion strip 13, which can ensure that the insertion strip 13 can fit tightly when inserted into the embedding groove 12 without loosening or falling off.

[0028] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
