[0023] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments.

[0024] Please refer to Figure 1-6, an embodiment provided by the present utility model: a polyurethane door and window with a sealing structure, including a first main window sash 1 and a second main window sash 101. On one side of the first main window sash 1, a side fixing frame 102 is fixedly arranged. On one side of the middle part of the front end face of the side fixing frame 102, a strip-shaped opening 103 is arranged. On the other side of the middle part of the front end face of the side fixing frame 102, a first strip-shaped magnetic pole plate 104 is arranged. Inside the side fixing frame 102 and on the inner side of the strip-shaped opening 103, a strip-shaped fixing member 2 is fixedly connected. Inside the strip-shaped fixing member 2, a moving groove 201 is arranged. On the rear end face of the moving groove 201, a plurality of first magnetic pole pieces 202 are fixedly connected. Inside the strip-shaped opening 103, a sealing plate 3 is arranged. The front end of the sealing plate 3 extends out of the strip-shaped opening 103 and is fixedly connected with a second strip-shaped magnetic pole plate 301. The rear end of the sealing plate 3 extends into the moving groove 201 and is fixedly connected with a plurality of linkage members 302. In the middle of the rear end of the linkage member 302, a second magnetic pole piece 303 is fixedly connected. The second main window sash 101 is obtained by rotating the first main window sash 1 by 180 degrees.

[0025] Furthermore, between the two side end faces of the strip-shaped fixing member 2 and the inner moving groove 201, a plurality of rectangular sliding grooves 203 are arranged. On both sides of each linkage member 302, a sliding rod 304 is fixedly connected.

[0026] Furthermore, the sliding rods 304 on both sides of the linkage member 302 are respectively inserted into the rectangular sliding grooves 203 on the two side end faces of the strip-shaped fixing member 2, so that when the linkage member 302 moves, it drives the sliding rod 304 to move along the rectangular sliding groove 203.

[0027] Furthermore, each first magnetic pole piece 202 is horizontally aligned with each second magnetic pole piece 303. When the first main window sash 1 and the second main window sash 101 move to separate the two side fixing frames 102, the second magnetic pole piece 303 is attracted by the first magnetic pole piece 202 to pull the linkage member 302, so that the linkage member 302 pulls the sealing plate 3 to retract into the strip-shaped opening 103 and move into the rectangular sliding groove 203, preventing the sealing plate 3 from blocking the movement of the first main window sash 1 and the second main window sash 101.

[0028] Furthermore, the second strip-shaped magnetic pole plate 301 at the front end of the sealing plate 3 on the first main window sash 1 attracts and fits with the first strip-shaped magnetic pole plate 104 on the second main window sash 101.

[0029] Furthermore, the second strip magnetic pole plate 301 at the front end of the sealing plate 3 on the second main body window sash 101 and the first strip magnetic pole plate 104 on the first main body window sash 1 attract and fit together. When the two side fixed frames 102 are fitted together, the first magnetic pole piece 202 and the second magnetic pole piece 303 are separated by the strong suction force between the second strip magnetic pole plate 301 and the first strip magnetic pole plate 104, and the second strip magnetic pole plate 301 pulls the sealing plate 3 to extend out of the strip opening 103 and fit with the first strip magnetic pole plate 104. The gap between the two side fixed frames 102 is sealed by the two sealing plates 3 extending out of the strip openings 103 on the first main body window sash 1 and the second main body window sash 101 respectively.

[0030] Furthermore, a rotating groove 305 is provided on the lower end surface of the sealed plate 3, and a roller 306 is provided inside the rotating groove 305. The roller 306 rotates inside the rotating groove 305 through the rotating shaft 307. The rotating groove 305 is extended from the lower end of the roller 306. The sealed plate 3 is supported by the roller 306, and the movement of the sealed plate 3 remains smooth.

[0031] Working principle: When in use, when the first main window sash 1 and the second main window sash 101 are staggered to close the window, the two side fixing frames 102 are fitted together, and the first magnetic pole piece 202 is separated from the second magnetic pole piece 303 by the strong suction force between the second strip magnetic pole plate 301 and the first strip magnetic pole plate 104, and the second strip magnetic pole plate 301 pulls the sealing plate 3 to extend out of the strip opening 103 and fit with the first strip magnetic pole plate 104, and the first main window sash 1 and the second main window sash are extended respectively through the two sealing plates 3 The strip opening 103 on 101 seals the gap between the two side fixed frames 102. During the window opening process, the second strip magnetic pole plate 301 separates from the first strip magnetic pole plate 104 to release the suction, and the first magnetic pole piece 202 attracts the second magnetic pole piece 303 to pull the linkage member 302, so that the linkage member 302 pulls the sealing plate 3 back into the strip opening 103 and moves it to the inside of the rectangular slide groove 203, preventing the sealing plate 3 from blocking the movement of the first main window sash 1 and the second main window sash 101.
