An aluminum alloy door and window with a blocking structure

Abstract

This utility model discloses an aluminum alloy door and window with a blocking structure, including a window frame profile and a window sash profile. The window frame profile includes a first outer frame and a first inner frame. A first thermal insulation strip is symmetrically snapped at the top and bottom of the first outer frame and the first inner frame. A first sealing strip is snapped at the top of the first thermal insulation strip. A second sealing strip is snapped at the inner top of the first outer frame. A first pressing part is integrally provided on the outer top of the first inner frame. Through the coordinated design of "four seals", the above-mentioned defects are fundamentally solved: the first outer basic seal (the second pressing part and the second sealing strip) and the second inner basic seal (the first pressing part and the third sealing strip) form a double basic defense line of "external rainwater protection and internal airflow blocking", dispersing most of the initial sealing pressure; the third middle seal (the first sealing strip and the third thermal insulation strip) fills the gap between the basic seals and avoids the formation of sealing blind spots.

Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy door and window technology, specifically relating to an aluminum alloy door and window with a blocking structure. Background Technology

[0002] Currently, building doors and windows generally adopt thermally broken aluminum alloy casement structures, which rely on sealing strips installed between the window sash profile and the main frame profile to achieve airtightness and watertightness. Existing common designs mostly adopt a two-point sealing structure, that is, sealing by pressing together one or two continuous sealing strips.

[0003] This structure has significant drawbacks: during the closing process, the window sash typically requires considerable force to ensure the locking points are in place, resulting in a substantial instantaneous impact between the sash and the main frame. As an elastic material, the sealing strip is prone to permanent deformation, fatigue aging, and decreased resilience under long-term, repeated impact and compression, leading to a rapid decline in sealing performance. Furthermore, the conventional two-point sealing strip structure provides limited cushioning, failing to effectively absorb and disperse the impact energy generated during closing, further accelerating the failure process of the sealing system and affecting the overall sound insulation, thermal insulation, and durability of the doors and windows.

[0004] Therefore, there is an urgent need for a new type of aluminum alloy door and window structure that can be optimized based on existing technology. This structure can distribute the sealing pressure by designing multiple sealing points and enhance the buffering performance between profiles, thereby extending the service life of the sealing material and improving the overall performance of the doors and windows. Utility Model Content

[0005] 1. To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy door and window with a blocking structure, comprising a window frame profile and a window sash profile, wherein the window frame profile comprises a first outer frame portion and a first inner frame portion, wherein a first thermal insulation strip is symmetrically snapped between the top and bottom of the first outer frame portion and the first inner frame portion, a first sealing strip is snapped onto the top of the first thermal insulation strip located at the top, a second sealing strip is snapped onto the inner side of the top of the first outer frame portion, and a first pressing portion is integrally provided on the outer side of the top of the first inner frame portion;

[0006] The window sash profile includes a second outer frame and a second inner frame. A window sash mounting groove, a second thermal break strip, and a third thermal break strip are sequentially provided from top to bottom in the gap between the second outer frame and the second inner frame. The second and third thermal break strips are respectively snapped into the inner sides of the second outer frame and the second inner frame. A second pressing part is integrally provided on the bottom outer side of the second outer frame. A third sealing strip is snapped into the bottom inner side of the second inner frame. The second sealing strip and the second pressing part are sealed by pressing between the first outer frame and the second outer frame. The first pressing part and the third sealing strip are sealed by pressing between the first inner frame and the second inner frame. The first sealing strip and the third thermal break strip are sealed by pressing between each other.

[0007] As a preferred technical solution of this utility model, the top of the first sealing strip is integrally provided with a plurality of first sealing protrusions, and the bottom of the third heat insulation strip is integrally provided with a plurality of second sealing protrusions. The plurality of first sealing protrusions and the plurality of second sealing protrusions correspond one-to-one, and the two are pressed together to seal.

[0008] As a preferred embodiment of the present invention, the height of the first sealing protrusion gradually decreases from the first outer frame portion to the first inner frame portion, and the height of the second sealing protrusion gradually decreases from the second outer frame portion to the second inner frame portion.

[0009] As a preferred embodiment of this utility model, the first heat insulation strip, the second heat insulation strip, the third heat insulation strip, the first sealing strip, the second sealing strip, and the third sealing strip are all provided with multiple cavities, and a support rib is integrally provided between adjacent cavities.

[0010] As a preferred embodiment of this utility model, the first heat insulation strip, the second heat insulation strip, and the third heat insulation strip are made of polyamide.

[0011] In a preferred embodiment of this invention, the first sealing strip, the second sealing strip, and the third sealing strip are all made of rubber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) Compared with the existing two-point sealing structure, this utility model fundamentally solves the above defects through the collaborative design of "four seals": the first outer basic seal (the second pressing part and the second sealing strip) and the second inner basic seal (the first pressing part and the third sealing strip) form a double basic defense line of "external protection against rainwater and internal airflow obstruction", dispersing most of the initial sealing pressure; the third middle seal (the first sealing strip and the third heat insulation strip) fills the gap between the basic seals and avoids the formation of sealing blind spots; the fourth sealing protrusion (the first sealing protrusion and the second sealing protrusion) has a higher outer protrusion height, which can withstand greater impact pressure, and a lower inner protrusion height, avoiding elastic loss caused by excessive compression. By dispersing the sealing pressure through "four seals", the problem of permanent deformation and elasticity attenuation caused by pressure concentration due to fewer sealing points is avoided.

[0014] (2) The dual thermal blocking design of thermal insulation strip and multi-cavity can reduce the thermal bridge effect of aluminum alloy profile and reduce the heat exchange between indoor and outdoor; the impact absorption effect of the cavity and the resilience of the support rib can alleviate the instantaneous impact when the door and window are closed and reduce the damage of the profile by collision.

The second sealing strip 5 and the second pressing portion 14 are sealed by pressing between the first outer frame portion 1 and the second outer frame portion 7. The first pressing portion 6 and the third sealing strip 15 are sealed by pressing between the first inner frame portion 2 and the second inner frame portion 8. The first sealing strip 4 and the third thermal break strip 11 are sealed by pressing.

[0024] In order to further increase the number of sealing contact points and form a multi-layered sealing structure to improve the overall airtightness and watertightness of doors and windows, in this embodiment, as a preferred technical solution of the present invention, the top of the first sealing strip 4 is integrally provided with multiple first sealing protrusions 12, and the bottom of the third heat insulation strip 11 is integrally provided with multiple second sealing protrusions 13. The multiple first sealing protrusions 12 and the multiple second sealing protrusions 13 correspond one-to-one and are pressed together to seal.

[0025] In order to adapt to the structural characteristics when the doors and windows are closed and avoid mutual interference, in this embodiment, as a preferred technical solution of the present invention, the height of the first sealing protrusion 12 gradually decreases from the first outer frame portion 1 to the first inner frame portion 2, and the height of the second sealing protrusion 13 gradually decreases from the second outer frame portion 7 to the second inner frame portion 8.

[0027] In order to effectively block the heat transfer path between the window frame and the window sash profile, reduce the thermal bridge effect, and improve the thermal insulation performance of the doors and windows, in this embodiment, as a preferred technical solution of the present invention, the first thermal insulation strip 3, the second thermal insulation strip 10 and the third thermal insulation strip 11 are made of polyamide.

[0028] In order to take advantage of the excellent elasticity, sealing properties and aging resistance of rubber materials and ensure that the sealing strip can tightly fill the gap during long-term pressing use, in this embodiment, as a preferred technical solution of the present invention, the first sealing strip 4, the second sealing strip 5 and the third sealing strip 15 are all made of rubber.

[0029] In summary, the specific working mechanism based on the above-described technical solution of this utility model is as follows:

[0030] I. Basic Structure: The window frame profile is mainly composed of the first outer frame part 1 and the first inner frame part 2. The two are connected by two first thermal insulation strips 3 to form a stable frame. The first thermal insulation strips 3 also bear the initial heat blocking function.

[0031] The window sash profile is supported by the second outer frame 7 and the second inner frame 8. From top to bottom, the gap between the two is provided with a window sash mounting groove 9 (used to fix the window sash glass and auxiliary components to ensure structural integrity), a second thermal insulation strip 10 and a third thermal insulation strip 11. The second thermal insulation strip 10 and the third thermal insulation strip 11 are connected by snap-fit ​​on both sides to form an independent force-bearing and thermal insulation unit that matches the window frame.

[0032] II. Multiple Sealing Effects: When the doors and windows are closed, the window frame and window sash form a three-dimensional sealing interface through four sets of sealing structures. The specific process is as follows:

[0033] First seal (outer seal): The second pressing part 14 at the bottom of the second outer frame part 7 contacts and presses against the second sealing strip 5 on the inner side of the first outer frame part 1. The gap is filled by the deformation of the sealing strip to block the intrusion of external airflow and rainwater.

[0034] The second seal (inner seal): The first pressing part 6 at the top of the first inner frame 2 is pressed together with the third sealing strip 15 (rubber material) on the inner side of the second inner frame 8 to strengthen the inner seal and form a double basic sealing defense line of "outer-inner".

[0035] The third seal (middle seal): The first sealing strip 4 on the first thermal insulation strip 3 at the top of the window frame (pressed together with the second thermal insulation strip 10 of the window sash, forming a transverse seal in the middle area between the window frame and the window sash, filling the gap between the basic seals).

[0036] The fourth seal (gradient precision seal): The first sealing protrusion 12 at the top of the first sealing strip 4 and the second sealing protrusion 13 at the bottom of the third thermal insulation strip 11 are pressed together in a one-to-one correspondence, and both adopt a gradient design of "high on the outside and low on the inside" to avoid obstruction when the doors and windows are closed.

[0037] III. Thermal insulation and cushioning functions

[0038] Thermal insulation mechanism: The first thermal insulation strip 3, the second thermal insulation strip 10 and the third thermal insulation strip 11 are all made of polyamide, which can block the heat transfer path of aluminum alloy profiles in window frame and window sash (avoiding the formation of thermal bridges); at the same time, the multiple cavities 16 inside each thermal insulation strip and sealing strip can reduce air convection heat transfer and further improve the thermal insulation effect.

[0039] Buffering mechanism: When the doors and windows are closed, the cavities 16 inside each thermal insulation strip and sealing strip absorb the instantaneous impact energy through compression deformation (reducing the direct collision between the window sash and the window frame); the support ribs 17 between adjacent cavities 16 can prevent the cavities 16 from being over-compressed and collapsing, while ensuring the structural strength and resilience of the thermal insulation strip and sealing strip, avoiding permanent deformation and fatigue aging caused by long-term impact.
