[0027] See also Figure 4 A sealing structure of a door and window is shown, and the water guide component 3 includes a bottom slide rail 301, the outer wall of the bottom slide rail 301 is provided with a water guide groove 302, and the side of the water guide groove 302 is provided with a vertical support rod 303, and the top of the vertical support rod 303 is fixedly connected with a horizontal support rod 304; the water guide grooves 302 are arranged at equal intervals with respect to the outer wall of the bottom slide rail 301, and the bottom slide rail 301, the vertical support rod 303, and the horizontal support rod 304 are all integrated.

[0028] Working principle: When encountering strong wind or rainy weather, close the door and window body 101. When closing, the splint 105 compresses the spring 104 outwardly under the support of the block 203, the inner sealing strip 204 and the middle sealing strip 205 inside the sealing component 2, so that the door and window body 101 is closed in place, and then the splint 105 is squeezed inward under the elastic action of the spring 104 to fit more closely with the block 203, the inner sealing strip 204 and the middle sealing strip 205 inside the sealing component 2, and the two splints 105 are connected to the door and window body 101 through the connecting piece 106 to form a "U" groove, and the connecting piece 106 is made of rubber material with a certain elasticity, which can prevent the connecting piece 106 from breaking when the splint 105 moves. When the weather is bad, the outer sealing strip 201 comes into play first. The outer sealing strip 201 is made of highly weather-resistant material, such as EPDM rubber, and is arranged on the outside of the door and window frame to resist external wind and rain. When some gas enters the door and window frame 202, it will be blocked by the inner sealing strip 204 and the middle sealing strip 205. The middle sealing strip 205 is made of sponge material with good elasticity and recovery, filling the gap between the door and window frame and the door and window sash. The inner sealing strip 204 is made of flexible material, such as rubber, and is tightly attached to the inside of the door and window frame for protective sealing. Rainwater falls on the door and window body 101, flows through the surface of the door and window body 101 into the bottom slide rail 301, and then flows out through the water guide groove 302, preventing excessive rainwater from seeping into the interior of the door and window body 101.
