The isobaric strip provided by the utility model can play a sealing role because the overlap of the first sealing strip with the heat insulation strip and the overlap of the second sealing strip with the side wall of the notch of the window sash can both play a sealing role, so the isobaric strip provided by the utility model can achieve double-position sealing through two sealing positions, thereby improving the airtightness and watertightness of the isobaric strip.

[0004] Although the prior art can achieve double-position sealing through two sealing positions, thereby improving the airtightness and watertightness of the isobaric seal strip, its own sound insulation and heat preservation effects are relatively poor. Utility Model Content

The isobaric rubber strip adopts EPDM foam material to manufacture support ribs and overlap surfaces. Compared with conventional pure EPDM material, the sealing performance is higher, the rebound force during the opening process is smaller, the comfort is high, and a first cavity and a second cavity are opened, so that the thermal insulation and sound insulation performance are higher and better, and the sealing and sound insulation effect of the rubber strip is increased to a certain extent.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a foamed composite isobaric adhesive strip, which includes a window frame 3, an isobaric adhesive strip 5, and a window sash frame 6. The upper part of the window frame 3 is connected to the lower part of the window sash frame 6, and an isobaric adhesive strip 5 is installed between the window frame 3 and the window sash frame 6. The isobaric adhesive strip 5 includes an upper foamed part and a lower dense part, and the left and right sides of the lower dense part of the isobaric adhesive strip 5 protrude outward to form a adhesive strip buckle 51. The upper foamed part of the isobaric adhesive strip 5 is provided with a supporting rib 52, and a lap joint surface 53 is provided on one side of the supporting rib 52.

[0007] Furthermore, a plurality of first cavities A are formed on the lower dense portion of the isobaric rubber strip 5 .

[0008] Furthermore, a second cavity B is defined on the supporting rib 52 .

[0009] Furthermore, a heat insulation strip 2 is installed in the window frame 3 .

[0010] Furthermore, a frame glue strip 1 is installed at the connection between one side above the window frame 3 and the window sash frame 6 , and a sash glue strip 4 is installed at the connection between the other side above the window frame 3 and the window sash frame 6 .

[0011] Furthermore, a strip groove for installing the isobaric strip 5 is formed on the window frame 3 , and a buckle groove 301 for installing and fixing the strip buckle 51 is formed on the side of the strip groove.

[0012] Furthermore, the upper foaming part of the isobaric rubber strip 5 is made of EPDM foaming material, and the lower dense part of the isobaric rubber strip 5 is made of high-elastic EPDM material.

[0013] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: the isobaric rubber strip adopts EPDM foam material to manufacture the supporting ribs and the overlapping surfaces, which has higher sealing performance than the conventional pure EPDM material, smaller rebound force during the opening process, high comfort, and a first cavity and a second cavity are opened, so that its thermal insulation and sound insulation performance is higher and better, which increases the sealing and sound insulation effect of the rubber strip to a certain extent.
