The frame member 10 is bolted to the wall and the sash member 20 is rotatably connected to the frame member 10 and the screen member 40 is rotatably connected to the screen member 30.

When the door and window is closed, the inner sealing strip 21 on the window sash member 20 is abutted against the inner frame 11, so that the inner sealing strip is tightly attached to the inner frame 11, and a gap between the window sash member 20 and the inner frame 11 is blocked, so that a first sealing structure is formed. The middle lower sealing strip 14 abuts the middle upper sealing strip 22 provided on the sash member 20 forming a second sealing structure.

The frame member 10, the window sash member 20, the frame member 30 and the screen sash member 40 are all made of metal, and the metal is strong in heat conduction, so that the thermal insulation performance of the door and window is reduced, and therefore, the frame member 10, the window sash member 20, the frame member 30 and the screen sash member 40 are not in direct contact connection, and the first sealing structure, the second sealing structure and the third sealing structure are installed between gaps, so that the conduction efficiency of heat between different materials is reduced, and the thermal insulation effect is achieved.

In addition, sound is transmitted through sound waves in air vibration, and the three sealing structures can block the sound wave transmission process for a plurality of times. In addition, the three sealing structures are all made of flexible materials, and when sound waves pass through one sealing structure, the sealing structure absorbs part of vibration to play a role in noise reduction, so that the sound insulation effect is improved as a whole.

As an example, referring to fig. 9 to 14, which are schematic cross-sectional views of the first cavity 111, the first cavity 111 is provided in the inner frame 11 to prevent heat conduction from the outside through the inner frame 11 and the outer frame 12, thereby improving heat insulation performance of the frame member. One or more regularly shaped cavities or irregularly shaped cavities are provided in the first cavity 111, which serves to reduce the heat transfer efficiency, and when heat is sequentially transferred outwards or inwards through one or more cavities, each cavity absorbs part of the heat and stores part of the heat in the cavity, thus reducing the heat transfer process and efficiency as a whole.

Specifically, the middle and lower positioning body 141 and the blocking member 13 may be in an integral structure, or may be fixedly connected in a hollow gap between the middle and lower positioning body 141 and the blocking member 13 through sealant. The function is to increase the stability of the middle and lower sealing strips 14 and to increase the service life of the middle and lower sealing strips 14. In addition, the overall stability of the door and window is increased.

The lower middle seal strip 14 has one or more first cavities 142 disposed therein. The first cavity 142 is a regular-shaped cavity or a shaped cavity. The effect is to reduce the heat transfer efficiency, and when heat is sequentially transmitted outwards or inwards through one or more cavities, each cavity will absorb part of the heat, and the heat transfer process and efficiency will be reduced as a whole, and in addition, the first cavity 142 is a cavity or a special-shaped cavity with a regular shape, and the strength and stability of the middle-lower sealing strip 14 can be improved.

While also increasing the stability between the inner rim 11 and the outer rim 12.

As an example, as shown in connection with fig. 1, the number of barrier ribs 131 is plural. To effectively reduce the heat conduction efficiency, the inner frame 11 and the outer frame 12 are separately arranged, so that the inner frame 11 and the outer frame 12 are not directly connected, and a separation seam 15 is formed between them. The time spent by heat conduction in different materials is different, and the conduction effect is different, and multiple materials are combined together, further separates heat conduction efficiency. Specifically, the blocking member 13 is disposed in the blocking slit 15, so that the inner frame 11, the outer frame 12 and the blocking member 13 are made of different materials, thereby reducing heat conduction efficiency.

The sealant 253 is filled between the adjacent barrier ribs 131.
