Abstract
Description
Technical Field
[0001] This application relates to the field of door and window equipment technology, specifically to a high-quality sealing structure door and window. Background Technology
[0002] Aluminum alloy doors and windows are widely used in residential, apartment, commercial, and high-rise buildings due to their lightweight, high strength, corrosion resistance, and aesthetic appeal. Especially in modern buildings, doors and windows not only provide lighting and ventilation but also play an important role in building energy conservation, thermal insulation, and sound insulation. However, traditional aluminum alloy doors and windows often exhibit poor sealing performance during long-term use. Particularly during the opening and closing process, their sealing structure struggles to balance good compression with flexible opening and closing operations, leading to defects such as air leakage, water seepage, and poor sound insulation when closed. Furthermore, some sealing structures are prone to permanent deformation after prolonged pressure, and the sealing performance gradually deteriorates over time, seriously affecting the service life and comfort of doors and windows.
[0003] In related technologies, a common practice is to install sealing strips or weatherstripping between the window frame and the window sash to improve the sealing effect. However, such structures are mostly single-seal designs with weak pressure resistance, which cannot effectively adapt to drastic changes in the external environment. Moreover, during the closing process of doors and windows, the pressing structure is limited by the rebound ability of the sealing strip itself, which often leads to problems with incomplete sealing. This cannot meet the higher requirements of high-performance buildings for the sealing performance of doors and windows. Utility Model Content
[0004] In view of this, this application provides a high-quality sealing structure door and window to solve the aforementioned technical problems.
[0005] This application discloses a high-quality sealing structure door and window, including a composite window frame and a movable window sash disposed on the composite window frame. The movable window sash opens / closes relative to the composite window frame. The movable window sash is equipped with composite glass. The movable window sash includes a first frame, a second frame, a connecting profile, and a first sealing body. The first frame and the second frame are arranged opposite to each other. The connecting profile and the first sealing body are arranged at intervals, and the two ends of the connecting profile and the first sealing body are respectively connected to the first frame and the second frame.

[0014] In one possible example, the line connecting the ends of the second sealing claws away from the contact area matches the outer wall profile of the first sealing body.
[0015] In one possible example, the first sealing claw has a second sealing chamber.
[0016] In one possible example, the first frame and the second frame are provided with snap-fit grooves on their facing sides, and the connecting profile and the first sealing body are provided with snap-fit blocks at both ends, the snap-fit blocks fitting into the snap-fit grooves.
[0017] In summary, compared with the prior art, this application discloses a high-quality sealing structure door and window, including a composite window frame and a movable window sash disposed on the composite window frame.

[0027] The technical solutions shown in this application will be described in detail below through specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the priority of the embodiments.
[0028] Please refer to Figures 1 to 3 The high-quality sealed structure door and window of this application embodiment includes a composite window frame 1 and a movable window sash 2 disposed on the composite window frame 1. The movable window sash 2 opens / closes relative to the composite window frame 1. The movable window sash 2 is provided with composite glass 3 to realize the door and window function.
[0029] In the specific implementation process, the movable window sash 2 includes a first frame 21, a second frame 22, a connecting profile 23, and a first sealing body 24. The first frame 21 and the second frame 22 are arranged opposite to each other, and the connecting profile 23 and the first sealing body 24 are arranged at intervals. The two ends of the connecting profile 23 and the first sealing body 24 are respectively connected to the first frame 21 and the second frame 22, thereby forming a frame-type edge-sealing structure, which is used to stably support the composite glass 3 embedded therein and enhance the overall structural strength and deformation resistance of the window sash.
[0030] Among them, the connecting profile 23 can be used to provide mechanical connection and structural reinforcement for the movable window sash 2. It can be made of aluminum alloy profile or other high-strength lightweight materials to enhance connection stability. The first sealing body 24 is used to press against the second sealing body 4 of the composite window frame 1 when the movable window sash 2 is closed to form a reliable seal.
[0031] Specifically, a second sealing body 4 is provided on one side of the composite window frame 1. The second sealing body 4 includes an integrally connected base area 5 and a contact area 6. The base area 5 is connected to the composite window frame 1. After the movable window sash 2 is closed relative to the composite window frame 1, the contact area 6 abuts against the first sealing body 24. A plurality of first sealing chambers 7 for deformation buffering are provided between the contact area 6 and the base area 5. The first sealing chambers 7 are filled with microporous elastomers 8.
[0032] Therefore, the contact area 6 is located at the free end of the base area 5, and its cross-sectional structure can be a convex or arc-shaped structure, which is used to effectively fit and press against the first sealing body 24 on it when the movable window sash 2 is closed, thereby forming a reliable sealing interface. In addition, the sealing chamber 7 is a closed or semi-closed structure, which is arranged at intervals along the length direction of the second sealing body 4. When the sealing chamber 7 is under pressure, it can generate controllable elastic deformation, effectively absorb the compressive stress generated when the window sash is closed, and enhance the resilience of the contact area 6, thereby improving the long-term stability and fatigue resistance of the sealing system.
[0033] Here, the first sealing chamber 7 is filled with a microporous elastomer 8 to enhance the buffering and energy absorption effect. The microporous elastomer 8 can be a closed-cell foam material, such as foamed silicone, EPDM foam, TPE / TPV foam or polyurethane foam. It has good resilience, small compression deformation, strong aging resistance and temperature resistance. By filling with microporous elastomer 8, the sealing compliance and pressure deformation resistance of the second sealing body 4 under the pressing state of the movable window sash 2 can be further improved, effectively avoiding the problem of sealing performance degradation due to long-term stress.
[0034] In one example, to further improve the connection strength and assembly convenience between the second sealing body 4 and the composite window frame 1, the base area 5 is integrally connected with the mounting body 51. The mounting bodies 51 are spaced apart on the side of the base area 5 facing the composite window frame 1, and the end of the mounting body 51 facing away from the base area 5 is connected to the composite window frame 1, thereby ensuring that the base area 5 is stably connected to the composite window frame 1 at multiple points through the mounting body 51.
[0035] Furthermore, the composite window frame 1 has a mounting groove 11 on the side facing the base area 5. The mounting groove 11 corresponds to the mounting body 51, and the mounting body 51 is engaged in the mounting groove 11 to form a reliable mechanical connection.
[0036] The mounting body 51 includes a snap-fit part 511 and a connecting part 512. The connecting part 512 connects the snap-fit part 511 and the base area 5 respectively, providing sufficient structural ductility and stress buffer without affecting the sealing performance. The snap-fit part 511 is matched in the mounting groove 11, and the snap-fit part 511 gradually tapers from the base area 5 towards the composite window frame 1, that is, the snap-fit part 511 has a wedge-shaped or inverted cone-shaped structure. The tapering structure design of the snap-fit part 511 ensures that its external dimensions closely match the cross-sectional shape of the mounting groove 11. When the snap-fit part 511 is inserted, it can be easily aligned and guided into the mounting groove 11. After being snapped in, it forms a self-locking fit, which has good anti-dislodgement ability. It also facilitates the rapid batch installation of multiple sealing bodies and improves production assembly efficiency.
[0037] In one example, to further enhance the structural stability and overall fit of the second sealing body 4, an auxiliary material body 52 is integrally connected to the base area 5. Several auxiliary material bodies 52 are evenly arranged between the mounting bodies 51, and the end of the mounting body 51 facing away from the base area 5 abuts against the composite window frame 1. The auxiliary material body 52 can be in the form of a strip or column to cooperate with the mounting body 51 to improve the support strength of the connection area between the sealing body and the composite window frame 1, and can also play a role in auxiliary sealing, buffering energy absorption and stable positioning to a certain extent.
[0038] In one example, to further improve the sealing integrity and installation aesthetics of the second sealing body 4, a cover body 53 is integrally connected to the base area 5. The cover body 53 is located on both sides of the base area 5 and extends to be interference-fitted with the composite window frame 1. Thus, after the second sealing body 4 is assembled, it covers the gap and edge structure of the installation area of the composite window frame 1, forming an assembly effect with continuous appearance, integrated structure and reliable sealing.
[0039] In one possible implementation of this application, to further improve the multi-point sealing performance and deformation resistance of the movable window sash 2 in the closed state relative to the composite window frame 1, a first sealing claw 61 and a plurality of second sealing claws 62 are integrally connected to the side of the contact area 6 away from the base area 5. The first sealing claw 61 and the second sealing claw 62 are evenly arranged on the contact area 6, and after the movable window sash 2 is closed relative to the composite window frame 1, the ends of the first sealing claw 61 and the second sealing claw 62 away from the contact area 6 are interference-fitted with the first sealing body 24 to jointly form a multi-seal structure, providing a stepped multi-point contact sealing effect during the closing process of the door and window.
[0040] Specifically, both the first sealing claw 61 and the second sealing claw 62 extend toward the first sealing body 24, that is, toward the movable window sash 2. Their free ends (i.e. the ends away from the contact area 6) form an interference fit with the first sealing body 24 when the door and window are closed, so that each sealing claw can generate a continuous pressing force when closed, thereby ensuring that the contact area has a good sealing and pressing effect at different stress points, effectively preventing air, water vapor or dust from penetrating.
[0041] In terms of structural design, the first sealing claw 61 is preferably located in the main force-bearing area of the contact area 6. Its size and shape are relatively large, and it has a strong clamping ability.
[0042] Furthermore, the line connecting the ends of several second sealing claws 62 away from the contact area 6 matches the outer wall contour of the first sealing body 24. The coordinated distribution and shape of the first sealing claw 61 and the second sealing claw 62 make the entire contact area 6 form a multi-level sealing structure combining main and auxiliary functions, effectively adapting to the minute deformation and assembly tolerances during the closing process of doors and windows.
[0043] The arrangement of multiple second sealing claws 62 in height and direction forms a sealing contact curve. This curve fits spatially with the outer wall surface of the first sealing body 24 (usually an arc, a slope, or a contour with certain variations), ensuring that the second sealing claws 62 form a uniform and stable multi-point contact with the first sealing body 24 when the door or window is closed. Through this curve-matching arrangement, the second sealing claws 62 can be set with different heights or inclinations at different positions according to the shape characteristics of the first sealing body 24, thereby achieving synchronous pressing, no obvious stress concentration, and no obvious joint fluctuations during the closing process.
[0044] In order to enhance the buffering deformation capacity and long-term resilience of the first sealing claw 61 during the opening and closing of doors and windows, a second sealing chamber 611 is provided inside the first sealing claw 61.
[0045] It should be noted that the first frame 21 and the second frame 22 are provided with snap-fit grooves 201 on their facing sides, and snap-fit blocks 202 are provided at both ends of the connecting profile 23 and the first sealing body 24. The snap-fit blocks 202 are matched in the snap-fit grooves 201. The snap-fit grooves 201 are preferably U-shaped or dovetail-shaped structures, which have good limiting and locking functions, and facilitate the stable assembly of components. The external structure of the snap-fit blocks 202 matches the snap-fit grooves 201 to achieve embedded connection in the structure. In the specific installation process, the snap-fit blocks 202 can be assembled into the snap-fit grooves 201 by insertion, pressing or slight snap-locking to form a stable mechanical fixing relationship, thereby forming a frame-type edge-wrapping structure.
[0046] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
