The words such as "include" or "contain" mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0023] As shown in Figure 1 , Figure 2 According to the embodiments of the present application, a sealing strip for a door and window system is provided, the door and window system comprising a window frame and a sash frame, the sealing strip for the door and window comprising a connected strip-shaped main body part and a strip-shaped extension part, the main body part being a solid strip structure, the extension part being a strip structure with a cavity structure, and both ends of the extension part being sealed, the main body part being connected with the window frame, a first side part of the extension part being connected with an outer surface of the main body part opposite to the sash frame, the extension part being obliquely arranged between the main body part, a second side part of the extension part abutting against an outer corner position of the sash frame, an inflation tube being arranged in the solid structure of the main body part, the inflation tube being communicated with the cavity structure of the extension part, so as to inflate the cavity structure of the extension part through the inflation tube.

[0024] The sash frame is connected with the glass, and the window frame is connected with the wall body. The sealing property of the sash frame and the window frame itself, and the sealing property between the sash frame and the window frame, affect the sealing property of the door and window system.

[0025] The main body part of the sealing strip of the present application is connected with the window frame to seal the window frame itself, and the extension part is connected with the sash frame to seal between the sash frame and the window frame. The extension part is an inflation structure, which can improve the sealing property between the extension part and the sash frame after inflation. The extension part adopts the inflation structure, and after the sealing strip is aged, the elasticity of the sealing strip decreases, but still has good sealing effect after inflation.

[0026] The main body part and the window frame are sealingly connected, and the extension part is arranged to be inclined relative to the main body part, so that the extension part can be obliquely overlapped with the outer corner position of the sash frame. When the main body part is deformed under the action of air pressure or the extension part is deformed under the action of air pressure, the main body part and the extension part can support each other, and the overall sealing performance will not be weakened due to the decrease in the sealing performance of each independent part. Compared with the L-shaped structure of the sealing strip, the sealing effect can be better improved.

[0027] In addition, the extension part is arranged to be inclined, one end part is connected with the main body part, and the other end part contacts the sash frame. After a small amount of gas is filled, the sealing effect of the main body part and the sealing effect of the extension part can be improved. After being inflated, it is not easy to separate from the sash frame and the window frame, and the stability is improved.

[0028] The inflation pipe can be connected with the air pump through the external pipe, and only a small air pump is needed to inflate it.

[0029] In some embodiments, the sealing strip is made of rubber or silicone. The sealing strip is made of a material with elasticity.

[0030] In some embodiments, the side wall of the extension part includes an arc segment and a straight line segment, so that the arc segment deforms after inflation, and the second side edge part of the extension part remains in abutment with the sash frame when not inflated. The straight line segment is connected with the main body part to support the extension part, so that the entire extension part can remain in abutment with the outer corner position of the sash frame.

[0031] In some embodiments, the inflation pipe is arranged to be inclined, and the inclination direction of the inflation pipe is consistent with the inclination direction of the extension part relative to the main body part. In this way, the airflow can enter the extension part obliquely, and the extension part can expand uniformly.

[0032] In some embodiments, the two side edges of the main body part are respectively provided with grooves. It is convenient to connect with the window frame.

The door and window system provided with the sealing strip according to any one of the embodiments of the present application has good sealing performance.

[0034] In some embodiments, the sash frame comprises a first side frame and a second side frame arranged vertically and having a transverse spacing, two first protruding parts are arranged at the outer corner position of the first side frame, and an included angle is formed between the two first protruding parts. The second side edge part of the extension part of the sealing strip abuts at the included angle position to seal the spacing between the window frame and the sash frame. The two first protruding parts can stabilize the extension part, and facilitate the stable connection of the end part of the extension part with the sash frame.

[0035] In some embodiments, the window frame comprises third and fourth side frames vertically arranged and having a lateral spacing, the third and fourth side frames are respectively provided with protrusions, the main body of the sealing strip is located between the third and fourth side frames, and the two side portions of the main body are respectively connected with the protrusions of the third and fourth side frames to seal the lateral spacing between the third and fourth side frames. The grooves of the two side portions of the main body of the sealing strip are respectively connected with the corresponding protrusions to achieve the effect of stability and sealing.

[0036] In some embodiments, the first and second side frames are connected by a heat insulation strip. The two side frames of the sash frame are connected by a heat insulation strip to achieve the effects of heat insulation and sealing.

[0037] In some embodiments, the third and fourth side frames are connected by a heat insulation strip. The two side frames of the window frame are connected by a heat insulation strip to achieve the effects of heat insulation and sealing.
