Description

TECHNICAL FIELD

[0001] The utility model relates to door and window sealing technical field, concretely relates to a right angle continuous inflation sealing structure. BACKGROUND

[0002] In the modern construction industry, system doors and windows as an important part of building envelope structure, its performance and aesthetic are increasingly valued by people. The sealing performance of system doors and windows is directly related to its key functions such as heat preservation, sound insulation, waterproof, and the sealing treatment of the corner is the key link. At present, the similar products widely used in the market generally adopt arc or round corner sealing form in the corner sealing design. Although this design can meet the basic sealing requirements to some extent, it exposes many limitations in the specific application scenarios of system doors and windows.

[0003] Specifically, the arc or round corner sealing form requires the shape of the opening fan to be adjusted by a large margin to adapt to the installation requirements of the adhesive tape. For the opening fan originally designed in a square shape, it means that it needs to be significantly rounded. This process not only increases the processing difficulty and manufacturing cost, but also may adversely affect the structural strength of the opening fan. In addition, the rounding process also reduces the area of the sight opening, i.e. the door and window glass area within the user's line of sight, which is undoubtedly a defect that cannot be ignored in modern buildings that pursue open and aesthetic vision.

[0004] More importantly, the arc or round corner sealing form often fails to meet the specific sealing performance requirements in the diversified application of system doors and windows. For example, in situations that require to withstand large wind pressure or have extremely high water tightness requirements, the traditional arc sealing form may not be able to provide sufficient sealing force, resulting in water seepage, air leakage and other problems. This not only affects the performance of doors and windows, but also may pose a potential threat to the overall safety and comfort of the building.

[0005] In view of the above limitations, a new type of corner sealing structure is needed to solve the deficiencies of the arc or round corner sealing form in the application of system doors and windows in the prior art. The new sealing structure should be able to achieve efficient and reliable sealing effect on the basis of maintaining the square shape of the opening fan, while not affecting the aesthetic and structural strength of the door and window.
