[0031] Figure 1 The soundproof and sealed aluminum profile door and window shown includes an outer window frame 1, an inner window frame 2 is hinged to the inner wall of the outer window frame 1, and two layers of soundproof glass are installed on the inner wall of the inner window frame 2. A sealing device 3 is provided on the surface of the outer window frame 1, and the sealing device 3 further improves the sealing and soundproofing effect of the door and window. A protective device 4 is provided on the soundproof glass on one side of the inner window frame 2.
[0032] Figure 1 , Figure 2 and Figure 3 The sealing device 3 shown includes two mounting shafts 31 installed on both sides of the outer window frame 1. Each mounting shaft 31 has a connecting block 32 fixedly connected to a mounting plate 33. A rubber pad 34 is fixedly connected to one side of the surface of the mounting plate 33, and a sponge pad 35 is installed on one side of the rubber pad 34. Positioning grooves 38 are respectively opened on both sides of the surface of the mounting plate 33. A rotating shaft 36 is fixedly connected to both sides of the surface of the outer window frame 1. A positioning plate 37 is rotatably connected to the arc surface of the rotating shaft 36. The surface of the positioning plate 37 has two protrusions that match the dimensions of the positioning grooves 38. When the aluminum profile doors and windows on the wall are closed to enhance the sealing and sound insulation effect, first, the inner window frame 2 is rotated to the closed state using hinges, and then the mounting plates 32 on both sides of the outer window frame 1 are rotated. 3. The connecting block 32 fixedly connected to the assembly plate 33 rotates on the arc surface of the mounting shaft 31 fixedly connected to the surface of the outer window frame 1. The two assembly plates 33 come into contact with each other. At the same time, the rubber pads 34 and sponge pads 35 on the two assembly plates 33 will cover the gap between the inner window frame 2 and the outer window frame 1. Then, the positioning plate 37 on the rotating shaft 36 is rotated, and the elastic deformation properties of the sponge pads 35 and rubber pads 34 are used to lock the protrusion on the positioning plate 37 into the positioning groove 38 on the surface of the assembly plate 33, so that the position of the assembly plate 33 is fixed. At this time, when the aluminum profile door and window are in the closed state, the sound insulation and sealing performance can be better guaranteed, the intrusion of external environmental noise can be reduced, thus helping to maintain the quiet environment indoors and improving the use effect and practicality of the aluminum profile door and window.
[0033] Figure 1 , Figure 2 and Figure 3The connecting block 32 shown has torsion springs 310 on both sides of its surface, which are respectively fitted onto the arc surface of the mounting shaft 31. The two sides of the torsion springs 310 are fixedly connected to the connecting block 32 and the mounting shaft 31, respectively. The torsion springs 310 allow the positioning plate 37 to disengage from the positioning groove 38 when the window needs to be opened. At this time, the mounting plate 33 will rotate under the torsional force of the torsion springs 310, which facilitates the opening and closing of the inner window frame 2 and improves the functionality of the sealing device 3. A reinforcing frame 39 is fixedly connected to the surface of the outer window frame 1. The inner wall specifications of the reinforcing frame 39 are adapted to the mounting frame. By setting up the reinforcing frame, when the components on the two mounting plates 33 cover and seal the gaps of the doors and windows, the outer sides of the two mounting plates 33 can be effectively reinforced with sealing measures, which improves the performance of the sealing device 3. The inner wall of the positioning groove 38 is fixedly connected with a reinforcing ring 311, which is a silicone ring. By setting up the reinforcing ring 311, when the positioning plate 37 is inserted into the positioning groove 38 to position the mounting plate 33, it fits better and is less likely to have gaps, ensuring the stability of the rubber pad 34 and the sponge pad 35, and achieving a better sealing and sound insulation effect.
[0034] Figure 1 and Figure 4 The protective device 4 shown includes a second Velcro 43 installed on the soundproof glass of the inner window. A first Velcro 42 is adhered to the surface of the second Velcro 43, and the surfaces of the first Velcro 42 and the second Velcro 43 are located on the hook and loop sides. A light-blocking plate 41 for blocking light and sunshade of the inner window frame 2 glass is fixedly connected to the surface of the first Velcro 42. When the doors and windows on the wall are closed and it is necessary to block the outside light, the first Velcro 42 fixedly connected to the light-blocking plate 41 is first pasted onto the second Velcro 43 on the inner window frame 2 glass. At this time, the light-blocking plate 41 will block the glass on the inner window frame 2, thereby blocking the outside light, which is convenient for the daily use of the people inside the room and improves the practicality and functionality of the doors and windows.
[0035] Figure 1 and Figure 4 The protective device 4 shown also includes a pull cord 44 fixed to the surface of the first Velcro 42, and the pull cord 44 pulls and removes the second Velcro 43. With the pull cord 44 fixedly connected to the first Velcro 42, when the light-blocking plate 41 covering the glass of the inner window frame 2 is covered, it can be quickly removed by pulling the pull cord 44, which improves the convenience of using the light-blocking plate 41. The surface of the light-blocking plate 41 is fixedly connected to a suction cup 45, which adheres to the glass surface of the inner window frame 2. With the suction cup 45, the light-blocking plate 41 is more stable when covering the glass of the inner window frame 2, and is less prone to shaking, which improves the stability and effectiveness of the light-blocking plate 41.
[0036] Working principle: When the aluminum profile doors and windows on the wall are closed, to enhance the sealing and sound insulation effect, the inner window frame 2 is first rotated to the closed position using hinges. Then, the mounting plates 33 on both sides of the outer window frame 1 are rotated, causing the connecting blocks 32 fixedly connected on the mounting plates 33 to rotate on the arc surface of the mounting shaft 31 fixedly connected to the surface of the outer window frame 1. The two mounting plates 33 come into contact with each other, and at the same time, the rubber pads 34 and sponge pads 35 on the two mounting plates 33 will cover the gap between the inner window frame 2 and the outer window frame 1. Then, the positioning plate 37 on the rotating shaft 36 is rotated, and the elastic deformation properties of the sponge pads 35 and rubber pads 34 are used to lock the protrusions on the positioning plate 37 into the positioning grooves 38 on the surface of the mounting plate 33, thus fixing the position of the mounting plate 33. At this time, when the aluminum profile doors and windows are in the closed position, the sound insulation and sealing performance can be better guaranteed, reducing the intrusion of external environmental noise, thereby helping to maintain a quiet indoor environment and improving the use effect and practicality of the aluminum profile doors and windows.
[0037] When the doors and windows on the wall are closed and it is necessary to block out outside light, firstly, the first Velcro 42 fixedly connected to the light-blocking plate 41 is pasted onto the second Velcro 43 on the glass of the inner window frame 2. At this time, the light-blocking plate 41 will block the glass on the inner window frame 2. Then, the suction cup 45 fixedly connected to the light-blocking plate 41 is attached to the glass of the inner window frame 2 to block outside light, which is convenient for the daily use of people indoors and improves the practicality and functionality of the doors and windows.
[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
