Technical Field

[0001] The utility model belongs to the technical field of building doors and windows, and specifically relates to a magnetic adsorption sealing structure for a system door and window. Background Art

[0002] The principle of heat-insulating broken bridge aluminum alloy is to insert a heat-insulating strip into the middle of the aluminum profile to disconnect the aluminum profile to form a broken bridge, effectively preventing the conduction of heat. Compared with ordinary aluminum alloy profile doors and windows, the heat conductivity of broken bridge aluminum doors and windows is sufficiently reduced. In the heat-insulating structure of broken bridge aluminum, in addition to the broken bridge formed by the heat-insulating strip, forming a heat-insulating cavity at the joint position is also an important technical means to ensure the heat-insulating effect. Moreover, such cavities are also crucial for the water tightness, air tightness and sound insulation effects of broken bridge aluminum doors and windows.

[0003] In the prior art, the broken bridge aluminum doors and windows generally have a three-seal structure. The three-seal structure is located between the fixed profile and the sash profile of the door and window, forming two heat-insulating cavities. It is very difficult to further improve its water tightness, air tightness and sound insulation effects during use. Summary of the Invention

[0004] The utility model aims at the technical defects of the prior art and provides a magnetic adsorption sealing structure for a system door and window to solve the technical problem that it is very difficult to further improve the water tightness, air tightness, sound insulation effects, etc. of the double heat-insulating cavities of the existing broken bridge aluminum doors and windows.

[0005] To achieve the above technical purposes, the utility model adopts the following technical solutions:

[0006] A magnetic adsorption sealing structure for a system door and window, including a fixed profile, a sash profile, a fixed heat-insulating strip, a sash heat-insulating strip, a first sealing strip, a second sealing strip, a third sealing strip, a first cavity, and a second cavity. Among them, the fixed profile has a fixed heat-insulating strip, the sash profile has a sash heat-insulating strip, the first sealing strip and the second sealing strip are respectively arranged at both ends between the fixed profile and the sash profile, the third sealing strip is arranged between the fixed heat-insulating strip and the sash heat-insulating strip, a first cavity is formed between the third sealing strip and the first sealing strip, and a second cavity is formed between the third sealing strip and the second sealing strip; at the same time, it also includes a first magnetic strip, a second magnetic strip, and a third cavity. Among them, the first magnetic strip is fixed inside the third sealing strip, the second magnetic strip is fixed on the side of the sash heat-insulating strip, the second magnetic strip and the first magnetic strip cooperate with each other, and a third cavity is formed among the first magnetic strip, the second magnetic strip, the third sealing strip, and the sash heat-insulating strip.

[0007] Preferably, the third sealing strip is an ethylene propylene diene monomer (EPDM) sealing strip.

[0008] Preferably, a slot is provided on the side of the sash heat-insulating strip, and the second magnetic strip is clamped in the slot.

[0009] Preferably, the first magnetic strip is the positive pole of the magnetic strip, and the second magnetic strip is the negative pole of the magnetic strip.

[0010] The utility model provides a magnetic adsorption sealing structure for a system door and window. In this technical solution, magnetic strips are respectively installed on the inner side of the ethylene propylene diene monomer (EPDM) sealing strip and the side of the broken bridge aluminum window sash. When the window sash is closed, the magnetic strips attract each other to form an independent cavity. The utility model changes the opening part of the broken bridge aluminum system window from the original two heat insulation cavities to three heat insulation cavities, achieving a better sealing effect. It further blocks the convection of hot and cold air inside and outside the house, further reduces heat conduction, reduces heat loss (or cold retention) inside the house, and promotes energy conservation and emission reduction. Moreover, the utility model further improves the water tightness, air tightness and sound insulation performance of the broken bridge aluminum system door and window.
