Description

Technical Field

[0001] This utility model relates to the field of door and window profile sealing technology, and in particular to a casement window profile with a reinforced sealing strip structure. Background Technology

[0002] Window and door profiles are generally made of aluminum alloy, but thermally broken aluminum profiles have rapidly gained market dominance due to their high strength, corrosion resistance, and ease of processing, leading to a period of rapid development for thermally broken aluminum windows and doors. With rising living standards and upgraded building energy efficiency standards, the market is placing higher demands on window and door performance. However, most mainstream thermally broken aluminum profiles currently use a single-cavity insulation structure, which cannot effectively reduce the heat exchange efficiency between the interior and exterior. Under conditions of large temperature differences, a cold bridge effect still exists, resulting in poor sealing and low thermal insulation performance.

[0003] As people's requirements for sound insulation, sealing, and heat insulation of doors and windows are increasing in daily life, existing profiles are difficult to meet these requirements due to design and production limitations. Therefore, they need to be continuously improved based on market demand and customer feedback. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a casement window profile with a reinforced sealing strip structure.

[0005] This utility model is achieved through the following technical solution:

[0006] A casement window profile with a reinforced sealing strip structure includes a window frame profile and a window sash profile. The window frame profile is provided with a first thermal break strip, and the window sash profile is provided with a shaped thermal break strip. A sealing strip is connected to the outside of the first thermal break strip. When the window frame profile and the window sash profile are closed, the sealing strip and the shaped thermal break strip are in contact. A shaped strip is provided at the connection between the sealing strip and the shaped thermal break strip.

[0007] According to the above technical solution, preferably, the interior of the sealing strip and the irregular heat insulation strip is a hollow structure, so that the middle part of the sealing strip and the irregular heat insulation strip forms a strip-shaped inner cavity.

[0008] According to the above technical solution, preferably, the sealing strip is snapped onto one side of the first heat insulation strip.

[0009] According to the above technical solution, preferably, the side of the first heat insulation strip is provided with a first strip-shaped groove, and the side of the sealing strip is provided with a first snap-fit ​​strip that matches the shape of the first strip-shaped groove, so that the first heat insulation strip and the sealing strip are connected.

[0010] According to the above technical solution, preferably, when the window frame profile and the window sash profile are closed, the sealing strip and the irregular heat insulation strip are partially attached, and the irregular heat insulation strip is connected to the sealing strip and the irregular heat insulation strip at the unattached parts.

[0011] According to the above technical solution, preferably, the irregularly shaped heat insulation strip is externally attached with an irregularly shaped adhesive strip.

[0012] According to the above technical solution, preferably, the side of the irregular heat insulation strip is provided with a second strip-shaped groove, and the side of the irregular adhesive strip is provided with a second snap-fit ​​strip that matches the shape of the second strip-shaped groove, so that the irregular heat insulation strip and the irregular adhesive strip are connected.

[0013] The beneficial effects of this utility model are:

[0014] This utility model improves the sealing and thermal insulation performance of the entire window system by adding a hollow structure and thickening the irregularly shaped thermal insulation strip and sealing strip, which increases the effective contact surface by generating misalignment deformation when the window is closed.

[0015] At the same time, adding a sealing and heat-insulating structure between the irregularly shaped heat insulation strip and the sealing strip effectively addresses the problem of sealing failure caused by temperature difference deformation or permanent deformation after long-term pressure on the sealing structure, resulting in better sealing of the entire window and preventing heat loss from the door and window system. This has high application and promotion value. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] As shown in the figure, this utility model includes a window frame profile 1 and a window sash profile 7. The window frame profile 1 is provided with a first thermal insulation strip 3, and the window sash profile 7 is provided with a shaped thermal insulation strip 11. A sealing strip 2 is connected to the outside of the first thermal insulation strip 3. When the window frame profile 1 and the window sash profile 7 are closed, the sealing strip 2 and the shaped thermal insulation strip 11 are in contact. A shaped strip 8 is provided at the connection between the sealing strip 2 and the shaped thermal insulation strip 11.

[0023] The sealing strip 2 and the irregular heat insulation strip 11 have hollow interiors, forming a strip-shaped inner cavity 6 in the middle of the sealing strip 2 and the irregular heat insulation strip 11. By adding hollow structures and thickening the irregular heat insulation strip 11 and the sealing strip 2, the effective contact surface is increased by the misalignment deformation when the window is closed, thereby improving the sealing performance and thermal insulation performance of the entire window system.

[0024] A sealing strip 2 is snapped onto one side of the first heat insulation strip 3. Specifically, the first heat insulation strip 3 has a first strip-shaped groove 5 on its side, and the sealing strip 2 has a first snap-fit ​​strip 4 on its side that matches the shape of the first strip-shaped groove 5, thus connecting the first heat insulation strip 3 and the sealing strip 2. A shaped heat insulation strip 11 is snapped onto the outside of a shaped adhesive strip 8. Specifically, the shaped heat insulation strip 11 has a second strip-shaped groove 9 on its side, and the shaped adhesive strip 8 has a second snap-fit ​​strip 10 on its side that matches the shape of the second strip-shaped groove 9, thus connecting the shaped heat insulation strip 11 and the shaped adhesive strip 8.

[0025] In this example, the cross-section of the irregularly shaped sealing strip 8 is L-shaped. When the window frame profile 1 and the window sash profile 7 are closed, the sealing strip 2 and the irregularly shaped thermal insulation strip 11 are partially adhered. Where the sealing strip 2 and the irregularly shaped thermal insulation strip 11 are not adhered, they are connected by the irregularly shaped sealing strip 8. This application adds a sealing and thermal insulation structure between the irregularly shaped thermal insulation strip 11 and the sealing strip 2, effectively addressing the problem of sealing failure caused by temperature difference deformation or permanent deformation after long-term pressure on the sealing structure. This results in a better overall window sealing effect and prevents heat loss from the door and window system.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
