Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile doors and windows, in particular to a noise-reducing aluminum profile door and window. Background Art

[0002] With the acceleration of the urbanization process, noise pollution has become one of the important factors affecting the quality of residents' lives. Traditional doors and windows often fail to meet the requirements of modern living environments in terms of sound insulation, especially in residential and commercial buildings near noise sources such as traffic arteries and industrial areas, where the sound insulation problem is particularly prominent.

[0003] Among the current sound-insulating aluminum profile doors and windows on the market, reference can be made to a heat-insulating and sound-insulating aluminum profile door and window disclosed in a Chinese utility model patent with the patent application number CN202221782805.2, which includes a base and a pedestal. The outer side of the pedestal is engaged with the inner side of the base. A first heat-insulating cavity is opened at the center of the base. A first sound-absorbing cavity and a second sound-absorbing cavity are respectively opened at both ends of the first heat-insulating cavity. A second heat-insulating cavity is opened at the center of the pedestal. A third sound-absorbing cavity and a fourth sound-absorbing cavity are respectively opened at both ends of the second heat-insulating cavity. Clamping strips are installed on both inner sides of the first heat-insulating cavity and the second heat-insulating cavity. A number of heat-insulating strips are clamped and installed between the two clamping strips on both sides. A first sealing strip is clamped and installed at the top of the first heat-insulating cavity. A second sealing strip is clamped and installed at the bottom of the second heat-insulating cavity. The first sealing strip and the second sealing strip are mutually attached. An installation groove is opened at one side of the upper end of the pedestal, and a resisting block is clamped and installed inside the installation groove. In this structure, the heat-insulating and sound-insulating effects of the aluminum profile door and window can be effectively improved, and the practical value can be improved.

[0004] However, since this aluminum profile door and window needs to be assembled by clamping the base and the pedestal, two different aluminum profiles need to be produced separately during the production process. The structures of the two aluminum profiles are relatively complex and inconvenient to assemble. Moreover, gaps are likely to appear after assembly, thus affecting the sound insulation effect. And after a long time, the connection may also become loose, further reducing the sound insulation effect. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a noise-reducing aluminum profile door and window.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A noise-reducing aluminum profile door and window, comprising a door and window frame and a glass panel. The glass panel is embedded inside the door and window frame. The door and window frame includes four strip-shaped side frames with the same structure. The side frame includes a rectangular frame body and a sound insulation board located inside the frame body and extending along the length direction. The cross-section of the sound insulation board is a V-shaped structure with the clamping opening facing the outside. The two ends of the sound insulation board are respectively connected to both sides of the frame body. Several groups of reflection boards extend from both sides of the sound insulation board along the outdoor and indoor directions respectively. The several reflection boards on both sides are arranged at intervals, and a sound absorption area for sound waves to bounce back is formed between adjacent two groups of reflection boards.

[0008] Furthermore, the side frame is integrally formed by stretching aluminum profiles. The two ends of the side frame are cut into symmetrical 45° inclined surfaces, and the four side frames are sequentially connected end to end to form the rectangular frame.

[0009] In the present utility model, an embedding groove for embedding the glass panel is further provided on the outer side of the side frame. The embedding groove is a rectangular groove, and the width of the embedding groove corresponds to the thickness of the glass panel.

[0010] Furthermore, there are two groups of embedding grooves, and the two groups of embedding grooves are arranged at intervals. The glass panel has two layers and is respectively embedded in the two groups of embedding grooves.

[0011] Furthermore, the glass panel and the embedding groove are fixedly connected by an adhesive.

[0012] Furthermore, a lip structure is provided at the notch of the outer side of the two groups of embedding grooves. The lip structure is biased towards the inner side of the notch. When the glass panel is embedded, the lip structure presses against the glass panel.

[0013] Furthermore, a spacer structure is provided between the two groups of embedding grooves. The most prominent point of the spacer structure is flush with the most prominent point of the lip structure.

[0014] In the present utility model, sound insulation cotton is further provided inside the side frame. The sound insulation cotton covers the inner side surface of the frame body and extends along the length direction of the side frame.

[0015] The present utility model has the following advantages and beneficial effects:

[0016] The integrally formed frame body and sound insulation board can improve the overall structural strength of the side frame, and there will be no loosening of the connection. Even when subjected to vibration, there will be no gaps, the stability of the door and window frame is higher, and the noise reduction function is better;

[0017] Moreover, a sound-absorbing area for sound waves to bounce is formed between adjacent groups of reflectors. When external sound waves reach the frame, the sound waves converge to one side of the clamping opening through the sound-insulating board with a V-shaped structure, and then are dispersed in the sound-absorbing area by several reflectors on one side of the clamping opening. The sound waves gradually weaken after multiple bounces in the sound-absorbing area, thus achieving the effect of noise reduction. Subsequently, the excess sound waves are dispersed to one side of the tip by the sound-insulating board with a V-shaped structure and are reflected to the sound-absorbing area by several reflectors on the tip side for secondary noise reduction. The two-stage noise reduction can fully weaken the sound waves, significantly reduce the sound wave energy, and improve the noise reduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As Figures 1 to 4 shown, this embodiment discloses a noise reduction type aluminum alloy profile door and window, including a door and window frame 1 and a glass panel 2. The glass panel 2 is embedded inside the door and window frame 1. The door and window frame 1 includes four long strip-shaped frames with the same structure. The frames are integrally formed by stretching aluminum alloy profiles. The two ends of the frames are cut into symmetrical 45° inclined planes. The four frames are sequentially connected end to end to form the rectangular door and window frame 1. The frame includes a frame body 11 with a rectangular cross-section and a sound insulation board 12 located inside the frame body 11 and extending along the length direction. The cross-section of the sound insulation board 12 is a V-shaped structure and the clamping opening faces the outdoor direction. The two ends of the sound insulation board 12 are respectively connected to both sides of the frame body 11. A plurality of groups of reflection boards 13 extend from both sides of the sound insulation board 12 along the outdoor and indoor directions respectively. The plurality of reflection boards 13 on both sides are arranged at intervals, and a sound absorption area 130 for allowing sound waves to bounce back is formed between adjacent two groups of reflection boards 13. When external sound waves are transmitted to the frame, the sound waves are converged to one side of the clamping opening by the V-shaped sound insulation board 12, and then are dispersed in the sound absorption area 130 by the plurality of reflection boards 13 on the side of the clamping opening. The sound waves are gradually weakened after multiple bounces in the sound absorption area 130, so as to achieve the effect of noise reduction. Subsequently, the redundant sound waves are dispersed to one side of the tip by the V-shaped sound insulation board 12 and are reflected again by the plurality of reflection boards 13 on the side of the tip into the sound absorption area 130 for secondary noise reduction. The two-stage noise reduction can fully weaken the sound waves, greatly weaken the sound wave energy, and improve the noise reduction effect; the integrally formed frame body 11 and the sound insulation board 12 can improve the overall structural strength of the frame, and there will be no loosening of the connection. Even if it is vibrated, there will be no gaps, and the stability of the door and window frame 1 is higher and the noise reduction function is better.

[0028] In this embodiment, an installation groove 14 for installing the glass panel 2 is further provided on the outer side of the frame. The installation groove 14 is formed by bending and recessing inward on the frame body 11 to form a rectangular groove structure. The width of the installation groove 14 corresponds to the thickness of the glass panel 2. Preferably, there are two groups of the installation grooves 14, and the two groups of installation grooves 14 are arranged at intervals. The glass panel 2 has two layers and is respectively installed in the two groups of installation grooves 14. Preferably, the glass panel 2 and the installation groove 14 are connected and fixed by an adhesive to improve the connection strength and sealing performance.

[0029] Furthermore, a lip structure 141 is provided at the notch of the outer side of the two groups of installation grooves 14. The lip structure 141 is biased towards the inner side of the notch. When the glass panel 2 is installed, the lip structure 141 presses against the glass panel 2. This can not only increase the connection area, but also, by setting the lip structure 141 at the joint between the frame and the glass panel 2 and then covering the lip structure 141 with a sealing edge adhesive, it can not only improve the connection stability, but also further improve the sealing effect.

[0030] Furthermore, a spacer structure 142 is provided between the two groups of installation grooves 14. The most prominent point of the spacer structure 142 is flush with the most prominent point of the lip structure 141, so that the forces on both sides of the glass panel 2 can be balanced.

[0031] In this embodiment, a sound insulation cotton 15 is further provided inside the frame. The sound insulation cotton 15 covers the inner side surface of the frame body 11. At the same time, the sound insulation cotton 15 extends along the length direction of the frame. During installation, the sound insulation cotton 15 is inserted into the frame body 11 from the end of the frame. By using the sound insulation cotton 15 to assist in noise reduction, the noise reduction effect can be improved without using other structures and without adding too much weight.

[0032] What is described above in this specification is only an example of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the content of this specification of the present invention or exceed the scope defined by this claim book, they should all belong to the protection scope of the present invention.
