Soundproofing structures are added to the frames of aluminum alloy doors and windows to effectively insulate and reduce noise when closed, protecting those inside.

[0003] After searching, for example, the patent publication number CN221074015U provides an aluminum alloy door and window with sound insulation function, which includes a window body, a sound insulation connection mechanism is provided on one side of the window body, and a docking guide mechanism is provided on the other side of the window. The sound insulation connection mechanism includes: a sound insulation component, which is provided on one side of the window; a connection component, which is provided at the connection between the sound insulation component and the window; a guide component, which is provided inside the connection component; through the designed sound insulation strips, the aluminum alloy doors and windows can play a certain role in sound insulation and noise reduction when closed, and at the same time, with the designed connection grooves, connection blocks, limit grooves, limit buckles and positioning screws, the sound insulation strips can also be quickly disassembled and assembled, which can effectively play a sound insulation role compared with the existing technology.

[0004] Based on the above search and in conjunction with existing technologies, it was discovered that the sound insulation sealing strips at the upper and lower ends of aluminum alloy doors similar to those disclosed above are generally fixed. As the aluminum alloy door slides horizontally back and forth, the sound insulation sealing strips constantly rub against the door frame, causing significant wear and tear, resulting in poor sound insulation when closed. Therefore, an aluminum alloy door with sound insulation is proposed to address this issue. Utility Model Content

[0005] The purpose of this application is to provide an aluminum alloy door with sound insulation function to solve the problems raised in the above background technology.

[0028] Example: Reference Figure 1-5 An aluminum alloy door with sound insulation function shown in the figure includes an aluminum alloy door body 1 and an aluminum alloy door frame 2 horizontally slidably installed on the inner side of the aluminum alloy door body 1. Specifically, sliders 3 are integrated on the upper and lower ends of the aluminum alloy door body 1, and a sliding groove 201 that is slidably adapted to the slider 3 is provided on the aluminum alloy door frame 2.

[0029] The upper and lower ends of the aluminum alloy door body 1 are both equipped with sealing blocks 4. The upper and lower ends of the aluminum alloy door body 1 are both provided with grooves. The sealing blocks 4 are vertically slidably installed on the inner side of the grooves. The side ends of the sealing blocks 4 are fixed with limit blocks 5. The horizontal inner side walls of the aluminum alloy door frame 2 are fixed with sealing guide blocks 6 and reset guide blocks 7 that are slidably adapted to the limit blocks 5. The specific shapes of the limit blocks 5, sealing guide blocks 6 and reset guide blocks 7 are as follows: Figure 3-5 Shown.

[0030] Based on the above structure, when the aluminum alloy door body 1 slides to close, the limit block 5 moves with the sealing block 4 under the guidance of the sealing guide block 6 to abut against the surface of the aluminum alloy door frame 2, ensuring a stable seal between the aluminum alloy door body 1 and the aluminum alloy door frame 2, thereby ensuring an effective sound insulation effect;

[0031] During the process of the aluminum alloy door body 1 sliding to open, the limit block 5, under the guidance of the reset guide block 7, moves the sealing block 4 to a position where it no longer contacts the surface of the aluminum alloy door frame 2, thereby avoiding wear of the sealing block 4 during the sliding process of the aluminum alloy door body 1, thereby ensuring the stable sealing and sound insulation performance of the sealing block 4.

[0032] Among them, sealing grooves 202 adapted to the sealing block 4 are provided on the upper and lower inner walls of the aluminum alloy door frame 2, and the sealing guide block 6 and the reset guide block 7 are both fixed on the side walls of the sealing groove 202, further improving the sealing and sound insulation effect.

The I-shaped support 43 can be made of aluminum alloy to ensure its strength and toughness, so that the sealing block 4 as a whole is not easy to deform. The first sealing strip 41 and the second sealing strip 42 are respectively fixed to the opposite side ends of the I-shaped support 43, and the limit block 5 is fixed to the I-shaped support 43.

[0034] In addition, the sealing block 4 also includes a mounting plate 44 and a tension spring 8. The mounting plate 44 is fixed to the inner side of the groove by screws. The first sealing strip 41, the second sealing strip 42, the I-shaped support 43 and the mounting plate 44 are all provided with corresponding through holes for the screws to pass through, which facilitates the replacement of the sealing block 4.

[0035] The tension spring 8 is fixed between the mounting plate 44 and the second sealing strip 42 , and can ensure that the sealing block 4 does not contact the aluminum alloy door frame 2 when the aluminum alloy door body 1 is not closed.

[0036] In order to ensure the stable vertical up and down sliding movement of the sealing block 4, a positioning slide column 45 that slides through the second sealing strip 42 and the I-shaped support member 43 is vertically fixed on the mounting plate 44. Four groups of limit blocks 5 are correspondingly provided on an aluminum alloy door body 1, and the four groups of limit blocks 5 are respectively provided at the two ends on the front and rear sides of the aluminum alloy door body 1. Four groups of sealing guide blocks 6 and reset guide blocks 7 are also correspondingly provided, and the four groups of sealing guide blocks 6 and reset guide blocks 7 are respectively located in the middle of the aluminum alloy door frame 2 and the end close to the closed end of the aluminum alloy door body 1.

[0037] Working principle of the utility model: When the aluminum alloy door body 1 slides to close, the limit block 5 moves with the sealing block 4 under the guidance of the sealing guide block 6 to the surface of the aluminum alloy door frame 2. At this time, the position of the limit block 5 relative to the sealing guide block 6 is as follows: Figure 5 It is shown that a stable seal is ensured between the aluminum alloy door body 1 and the aluminum alloy door frame 2, thereby ensuring effective sound insulation effect;

[0038] During the process of the aluminum alloy door body 1 sliding to open, the limit block 5 is guided by the reset guide block 7 so that the sealing block 4 moves to a position where it does not contact the surface of the aluminum alloy door frame 2. At this time, the position of the limit block 5 relative to the sealing guide block 6 and the reset guide block 7 is as follows: Figure 4 It is shown that the sealing block 4 is prevented from being worn during the sliding process of the aluminum alloy door body 1, thereby ensuring the stable sealing and sound insulation performance of the sealing block 4.

[0039] Of course, a conventional sealing and sound insulation structure (not shown in the figure) is provided between the vertical side surface of the aluminum alloy door body 1 and the aluminum alloy door frame 2 .
