Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a sound insulation structure for aluminum alloy doors and windows. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes. Currently, people have an increasing demand for soundproof environments, and this has led to an increasing demand for soundproof aluminum alloy doors and windows.

[0003] For example, CN 117780229 B discloses a soundproof aluminum alloy door and window. The door and window are slidably connected to one another in the two slidable slots. Each of the two doors and windows has a groove cavity within the frame, containing hydraulic oil. Sliding seats are slidably and sealingly connected to each cavity. The sliding seats are fixedly connected to multiple rubber retainers, and multiple elastic members are positioned between the rubber retainers and the inner end surfaces of the groove cavity. This door and window increases the mutual engagement force between the rubber retainers on the two sliding seats, thereby improving the seal between the two doors and windows, thereby enhancing the soundproofing effect. However, the following problems still exist: the soundproofing structure uses heated hydraulic oil and transfers the heat to the rubber retainers to ensure full contact between the rubber retainers on the two sliding seats. However, the packaging and debugging of the hydraulic oil are cumbersome, and it is also inconvenient to inspect and maintain, resulting in poor practicality. Utility Model Content

[0004] The purpose of the utility model is to provide a sound insulation structure for aluminum alloy doors and windows with a reasonable structure and reliable use to solve the above problems. While ensuring the sound insulation effect, it is easy to assemble, easy to repair and maintain, and has strong practicality.

[0021] The utility model is described in detail according to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, the sound insulation structure for aluminum alloy doors and windows includes an aluminum alloy frame and a sealing component.

[0023] A sealing groove extending along the height direction of the aluminum alloy frame 8 is provided on one side edge of the aluminum alloy frame 8 , a positioning baffle 9 parallel to the bottom surface of the sealing groove is provided in the sealing groove, and a long through opening is provided on the top surface of the sealing groove.

[0024] The sealing assembly includes a support frame 6 inserted into the sealing groove, multiple positioning grooves 10 provided in the support frame 6, a heating rod 14 provided at the bottom of the positioning groove 10, a spring 4 sleeved on the outside of the heating rod 14, a positioning cover 3 fastened to the top of the positioning groove 10, a push plate 11 contacting the top surface of each positioning cover 3, and a sealing rubber sheet 1 connected to the top surface of the push plate 11. In this embodiment, a junction box 12 is provided on the bottom surface of the sealing groove. The output end of the junction box 12 is connected to the conductive cable of each heating rod 14, and the input end of the junction box 12 is connected to an external power source.

[0025] The upper edge of the support frame 6 is in close contact with the lower surface of the positioning baffle 9. Each positioning cover 3 is located in the space surrounding the positioning baffle 9. The push plate 11 is located above the positioning baffle 9. A sealing buffer ring 7 is fixed to the upper edge of the push plate 11. The inner top surface of the sealing groove is in close contact with the sealing buffer ring 7. The top surface of the sealing rubber sheet 1 protrudes from the long through-hole. In this embodiment, the top surface of the sealing rubber sheet 1 is a corrugated surface to enhance sealing. The outer periphery of the upper edge of the positioning groove 10 is provided with an annular socket corresponding to the positioning cover 3. The lower edge of the positioning cover 3 is inserted into the annular socket, which improves positioning.

[0026] The bottom of the positioning groove 10 contacts the bottom surface of the sealing groove and is provided with multiple arched concave surfaces at the bottom of the positioning groove 10. The length of each arched concave surface is perpendicular to the length of the sealing groove. Insulation strips 13 are provided between each arched concave surface and the bottom surface of the sealing groove.
