Description

Technical Field

[0001] The utility model relates to the technical field of door and window equipment, in particular to a door and window sealing structure. Background Art

[0002] Doors and windows are important components of buildings. They not only provide indoor and outdoor ventilation and lighting, but also have certain insulation, sound insulation, waterproof and safety functions.

[0003] The sealing structure in doors and windows is one of the key technologies to ensure the performance of doors and windows. It is directly related to the insulation, sound insulation, waterproof and dustproof functions of doors and windows. With the continuous improvement of people's requirements for building comfort and energy saving, the importance of door and window sealing technology has become increasingly prominent. In traditional door and window manufacturing, sealing usually relies on simple sealing strips or rubber strips.

[0004] In the current casement window or casement door design, in order to achieve a good sealing effect, a sealing strip slot is usually set between the muntin profile and the door frame or window frame profile, and the sealing strip is fixed in the slot. However, there is a problem with this design: when the cross-connection part between the muntin and the door frame or window frame cannot form a continuous and smooth closed loop, the sealing strip needs to be disconnected for inlaying or bonding to ensure the integrity of the connection. Nevertheless, practice has shown that this method may lead to reduced ventilation and waterproof performance.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original door and window sealing structure. Utility Model Content

[0006] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution of door and window sealing structure which is significantly different from the existing technology, so as to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door and window sealing structure, including a window frame, a horizontal center brace component connected to the window frame, and a group of conversion frame components are respectively installed between one side of the window frame and one side of the horizontal center brace component, and a window sash is arranged between the two groups of conversion frame components, and a frame-laying rubber strip is tightly clamped between the sides of each group of the conversion frame components and the sides of the window sash, and a multi-cavity isobaric rubber strip is tightly clamped in the middle area on both sides of the window frame, and the multi-cavity isobaric rubber strip is connected to the corresponding conversion frame component.

[0008] Preferably, a plurality of heat insulating components for thermal insulation and sound insulation are tightly clamped between the window frame, the horizontal center support component and the interior of the conversion frame component.

[0009] Preferably, the window sash comprises an outer frame, an insulation strip, an inner frame, a bracket, a first sealing strip, a second sealing strip, tempered insulating glass, and a gasket. A plurality of insulation strips are clamped on the inner side of the outer frame, and the other end of each insulation strip is correspondingly clamped and connected to the inner frame. A bracket is clamped on each of the inner frames, and a tempered insulating glass is provided between each bracket and the outer frame. A first sealing strip is connected between each bracket and the tempered insulating glass, and a second sealing strip is connected between each outer frame and the tempered insulating glass, and a gasket is provided between the side of the tempered insulating glass and the outer frame and the inner frame.

[0010] Preferably, the second sealing strip is an extra-glass composite foaming strip.

[0011] Preferably, the outer side of the end of the frame-building rubber strip in contact with the window sash is configured to be sloped.

[0012] Preferably, at least three hollow chambers are arranged in the multi-cavity isobaric rubber strip.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the sealing structure of doors and windows realizes a triple sealing mechanism by carefully designing components such as frame-building strips and multi-cavity isobaric strips, and in particular, innovative improvements are made to the sealing of the middle multi-cavity strips. Traditional sealing strips are mostly installed on the conversion frame and the outer frame, while the present application places them on the fan surface, which effectively reduces the height of the facade and expands the field of view. The cavity design on the multi-cavity strip increases the volume of the strip itself, better fills the gap between the window frame and the window sash, thereby preventing air and moisture from penetrating, and improving the thermal insulation and waterproof performance of doors and windows. In addition, this design also provides additional support for the strip, ensuring stability during the opening and closing of doors and windows, and preventing deformation or functional failure of the strip due to temperature fluctuations or other environmental influences.
