Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic doors and windows technology, and in particular to a silent aluminum-plastic door and window. Background Technology

[0002] Aluminum-plastic composite doors and windows have been widely used in the construction industry due to their combination of the strength and durability of aluminum alloys and the excellent thermal insulation properties of plastic profiles. However, with urban development, noise pollution from traffic, commerce, and daily life is becoming increasingly serious, and people's demand for quiet living and working environments is constantly increasing. The sound insulation performance of existing aluminum-plastic doors and windows can no longer fully meet the needs of the high-end market. The sound insulation performance of doors and windows mainly depends on their overall sealing performance to prevent the transmission of airborne sound. Currently, the mainstream silent doors and windows on the market generally adopt a double-sealing structure, that is, two sealing strips are set on the closing path of the window sash and the window frame.

[0003] Traditional double-seal systems typically use homogeneous sealing strips with similar physical properties. When faced with complex and variable wind pressure and sound wave frequencies, they cannot form an effective gradient barrier, which seriously affects the sound insulation effect of aluminum-plastic doors and windows. Utility Model Content

[0004] Therefore, it is necessary to address the problem that traditional double-seal systems typically use homogeneous sealing strips with similar physical properties, which cannot form an effective gradient barrier when facing complex and variable wind pressure and sound wave frequencies, thus seriously affecting the sound insulation effect of aluminum-plastic doors and windows. A sound-insulating aluminum-plastic door and window should be provided.

[0005] A silent aluminum-plastic door and window includes: a door and window mechanism, the door and window mechanism including a window frame and two sets of window bodies installed inside the window frame, and a window lock is provided on the side of one set of the window bodies; A noise reduction mechanism, comprising a side plate, a magnetic rubber strip, a shaped sealing strip, a snap-fit ​​sealing strip, and an inner sealing assembly for sealing between two sets of windows; The side panel is fixedly installed on the outside of the window, the magnetic rubber strip is installed on the inside of the window frame, the magnetic rubber strip is installed on the inside of the side panel, the irregular sealing strip is installed on the inside of the window, the snap-fit ​​sealing strip is installed on the inside of the window frame, and the irregular sealing strip is installed on the inside of the snap-fit ​​sealing strip.

[0006] In one embodiment, the side plate has a snap-fit ​​groove corresponding to the magnetic rubber strip inside, and a magnetic head corresponding to the magnetic rubber strip is provided at the top of the snap-fit ​​groove.

[0007] In one embodiment, the lower surface of the magnetic rubber strip is provided with a limiting plate via an extension block, and a limiting groove corresponding to the limiting plate is provided inside the window frame.

[0008] In one embodiment, the inner sealing assembly includes an inner sealing strip and an outer sealing strip, the inner sealing strip and the outer sealing strip respectively corresponding to the window connection.

[0009] In one embodiment, the inner sealing strip and the outer sealing strip are located on the corresponding surfaces of the two sets of windows, and the outer sealing strip has a sealing groove on its side that corresponds to the inner sealing strip.

[0010] In one embodiment, the inner sealing strip is chamfered at the end near the outer sealing strip, and the outer sealing strip is chamfered at the end near the inner sealing strip.

[0011] In one embodiment, the magnetic rubber strip is a hard rubber strip, and the irregularly shaped sealing strip and the snap-fit ​​sealing strip are soft rubber strips.

[0012] In one embodiment, the end of the snap-fit ​​sealing strip near the irregular sealing strip is chamfered, and the side of the irregular sealing strip has a movable groove corresponding to the snap-fit ​​sealing strip.

[0013] Beneficial effects 1. The aforementioned silent aluminum-plastic doors and windows achieve a gradient seal with complementary physical properties through a three-tiered sealing system consisting of magnetic rubber strips, irregularly shaped sealing strips, and snap-fit ​​sealing strips. The magnetic rubber strips utilize magnetic force to achieve an initial tight closure, eliminating installation tolerances and resisting strong wind pressure; the irregularly shaped sealing strips act as the main sealing barrier, expanding in multiple directions to fill gaps under pressure; and the inner snap-fit ​​sealing strips ensure final airtightness and long-term structural stability, thereby improving the overall sound insulation performance of the aluminum-plastic doors and windows.

[0014] 2. The aforementioned silent aluminum-plastic doors and windows feature a chamfered sealing strip that mates with the movable groove of the irregularly shaped sealing strip, as well as chamfered inner and outer sealing strips that mate with the sealing groove. This allows each sealing strip to smoothly align and compress during the closing process, effectively preventing edge curling and wear caused by misalignment or compression, thereby improving the reliability and durability of the sealing mechanism.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. 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.

[0019] The following is combined Figures 1-6 This invention describes a silent aluminum-plastic door and window.

[0020] In one embodiment, a silent aluminum-plastic door and window includes: a door and window mechanism 100, which includes a window frame 101 and two sets of window bodies 102 installed inside the window frame 101, with a window lock 103 provided on the side of one set of window bodies 102; and a silent mechanism 200, which includes a side panel 201, a magnetic rubber strip 202, a shaped sealing strip 208, a snap-fit ​​sealing strip 209, and an inner sealing assembly for sealing between the two sets of window bodies 102; the side panel 201 is fixedly disposed on the outside of the window body 102, the magnetic rubber strip 202 is disposed on the inside of the window frame 101, the shaped sealing strip 208 is disposed on the inside of the window body 102, and the snap-fit ​​sealing strip 209 is disposed on the inside of the window frame 101, with the shaped sealing strip 208 disposed on the inside of the snap-fit ​​sealing strip 209; In this embodiment, when the window 102 is closed, the magnetic rubber strip 202 installed on the window frame 101 first attracts the magnetic head 204 installed on the side panel 201 of the window 102, forming the first windproof and preliminary sound insulation barrier; then, the window lock 103 locks both sets of windows 102, and the irregularly shaped sealing strip 208 on the window 102 and the snap-fit ​​sealing strip 209 on the window frame 101 are squeezed and fitted together to form a tighter main sealing strip; finally, the inner sealing assembly ensures the seal at the closure of the two windows. This creates a stepped sealing effect from the outside to the inside.

[0021] like Figure 5 As shown, the magnetic rubber strip 202 is made of hard rubber, while the irregular sealing strip 208 and the snap-fit ​​sealing strip 209 are made of soft rubber. The snap-fit ​​sealing strip 209 has a chamfered end near the irregular sealing strip 208, and the irregular sealing strip 208 has a movable groove on its side that corresponds to the snap-fit ​​sealing strip 209. In this embodiment, the rigid magnetic rubber strip 202 provides sufficient structural support to maintain the flatness and stability of the magnetic surface; the soft, irregularly shaped sealing strip 208 and the snap-fit ​​sealing strip 209 utilize their high elasticity and resilience to ensure that they can fully fill the gaps and maintain a lasting sealing pressure under pressure. The chamfered edges and movable grooves of the irregularly shaped sealing strip 208 and the snap-fit ​​sealing strip 209 have a guiding and fault-tolerant function, allowing the snap-fit ​​sealing strip 209 to slide into the predetermined position along the chamfer of the irregularly shaped sealing strip 208 in the final stage of closing the window sash, while the movable groove provides space for the final compression and fitting of the two, avoiding rigid collisions and interference, and ensuring the smoothness and integrity of the sealing action.

[0022] like Figure 2 , Figure 3 and Figure 5 As shown, the side panel 201 has a snap-fit ​​groove 203 corresponding to the magnetic rubber strip 202 inside, and a magnetic head 204 corresponding to the magnetic rubber strip 202 is provided at the top of the snap-fit ​​groove 203; a limit plate 206 is provided on the lower surface of the magnetic rubber strip 202 through an extension block, and a limit groove 207 corresponding to the limit plate 206 is provided inside the window frame 101. In this embodiment, the engagement of the snap-fit ​​groove 203 and the magnetic suction head 204 ensures the effective working surface and engagement accuracy of the magnetic attraction; the engagement of the limiting plate 206 and the limiting groove 207 strengthens the installation and fixing structure of the magnetic rubber strip 202. After the limiting plate 206 is embedded in the limiting groove 207, it can effectively prevent the magnetic rubber strip 202 from loosening or slipping during frequent magnetic attraction and separation, thus ensuring the long-term effectiveness and reliability of the first seal.

[0023] like Figure 2 and Figure 6As shown, the inner sealing assembly includes an inner sealing strip 205 and an outer sealing strip 210, which are connected to the corresponding windows 102. The inner sealing strip 205 and the outer sealing strip 210 are located on the corresponding surfaces of the two sets of windows 102. A sealing groove 211 corresponding to the inner sealing strip 205 is opened on the side of the outer sealing strip 210. The end of the inner sealing strip 205 near the outer sealing strip 210 is chamfered, and the end of the outer sealing strip 210 near the inner sealing strip 205 is also chamfered. In this embodiment, the inner sealing assembly employs an interlocking sealing principle between the inner sealing strip 205 and the sealing groove 211. When both windows are closed, the chamfered inner sealing strip 205, guided by the surrounding material, more easily embeds into the sealing groove 211 of the outer sealing strip 210, forming a labyrinthine sealing interface that significantly increases the resistance to sound and airflow through the gap. The double chamfer design ensures a smooth closing process and prevents the sealing strip from being damaged or displaced due to direct impact.

[0024] Working principle: When window 102 is closed, the rotation of window lock 103 moves the window sash towards window frame 101 and locks it in place. During this process, the magnetic head 204 on the side panel 201 first magnetically attracts the magnetic rubber strip 202 on window frame 101, completing the first seal. As the window sash continues to press down, the irregularly shaped sealing strip 208 on window 102 and the snap-fit ​​sealing strip 209 on window frame 101 are guided by chamfering to press against each other and fit tightly, forming the second main sealing barrier. Simultaneously, the inner sealing strip 205 and outer sealing strip 210 on both window sashes 102 also interlock under chamfering guidance, closing the central seam channel. Finally, through these three working sealing lines, external noise is effectively isolated from the outside.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
