[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4 The door and window sealing structure shown includes a mounting frame 1, a glass frame 2, a handle 3, and a movable plate 4. The glass frame 2 is movably mounted inside the mounting frame 1. The handle 3 is movably mounted on the front surface of the glass frame 2 and near one side. The movable plate 4 is movably embedded on one side surface of the glass frame 2.

[0022] An inlay groove 101 is formed on one inner surface of the mounting frame 1, and a locking groove is formed on one inner surface of the mounting frame 1 in front of the inlay groove 101. A storage groove 201 is formed on one side surface of the glass frame 2, and a plate groove 202 is formed behind the storage groove 201. Limiting grooves 203 are formed on the upper and lower inner surfaces of the plate groove 202. The plate groove 202 is connected to the storage groove 201, and the storage groove 201 can store the rubber rod 402 when not in use. A rotating rod 301 is fixedly installed on the rear surface of the handle 3. The rear end of the rotating rod 301 extends into the plate groove 202. A locking plate 303 is fixedly sleeved on the surface of the rotating rod 301 inside the plate groove 202. A gear 302 is fixedly sleeved on the surface of the rotating rod 301 inside the plate groove 202 and behind the locking plate 303. The rotating handle 3 uses the gear 302 to rotate. 2 can drive the movable plate 4 to move back and forth; the upper and lower surfaces of the movable plate 4 are fixedly installed with limit sliders 401, the front surface of the movable plate 4 is fixedly installed with a rubber rod 402, the rear surface of the movable plate 4 and the middle part are provided with a groove 403, and the lower surface of the inner side of the groove 403 is provided with a toothed groove 404; the movable plate 4 is embedded in the plate groove 202, the limit slider 401 is embedded in the limit groove 203, the gear 302 meshes with the toothed groove 404, the cooperation between the limit slider 401 and the limit groove 203 can prevent the movable plate 4 from detaching from the plate groove 202; the width of the storage groove 201 is greater than the width of the plate groove 202, the rubber rod 402 is embedded in the embedding groove 101, the locking plate 303 is embedded in the locking groove, the cooperation between the rubber rod 402 and the embedding groove 101 can increase the sealing performance of the glass frame 2 after it is closed.
