Description

Technical Field

[0001] The present application relates to the field of silent window frames, and in particular to a silent window frame capable of reducing the transmission of acoustic shock. Background Art

[0002] With the improvement of living standards, people begin to pay more and more attention to the sound insulation of houses. For house construction, in addition to the walls themselves, doors and windows are also part of the house construction. In most cases, since doors and windows are not like walls, their own thickness cannot be compared with the cavity, so the sound insulation of door frames becomes particularly important.

[0003] Typically, a window frame profile with heat insulation and sound insulation functions, such as the Chinese patent announcement number CN220979219U, has a main sound insulation structure that is a multi-layer stacked structure through right-angle connectors and connected as a whole through fixing nails. The multi-layer structure includes at least an inner metal reinforcement layer and an outer sound insulation filling layer, and the sound insulation filling layer is in contact with the metal inner surface of the main frame and the glass support body.

[0004] Although the sound insulation structure in the above scheme of the inventor has a certain sound insulation effect, there is still room for improvement as a whole, because its sound insulation filling layer is arranged on the right-angle connector, and the right-angle connector is installed at the corner connection of the window frame. Relatively speaking, it is limited to the corners of the window frame and has a certain sound insulation effect, but for the parts other than the corners, the sound insulation effect is relatively general. Therefore, the inventor believes that there is still room for improvement in sound insulation. Summary of the invention

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1 This application is described in further detail.

[0021] The present application embodiment discloses a silent window frame that reduces the transmission of acoustic shock, referring to Figure 1 , including a first frame body 1 and a second frame body 2, glass installation positions 3 are formed on opposite sides between the first frame body 1 and the second frame body 2, two first arms 4 are arranged parallel to and at intervals in the middle position of the first frame body 1 toward the second frame body 2, and two second arms 5 are arranged parallel to and at intervals in the middle position of the second frame body 2 toward the first frame body 1, and a sound insulation frame is installed between the two first arms 4 and the two second arms 5. In order to improve the sound insulation performance, the first frame body 1 and the second frame body 2 are made of aluminum alloy or steel, and the sound insulation frame is made of hard plastic. Compared with aluminum alloy or steel, the sound conduction effect of plastic is relatively poor. Therefore, as a manufacturing material of the sound insulation frame, it can enhance the sound insulation performance, and at the same time, it can well support the first frame body 1 and the second frame 2, and improve the structural stability after assembly.

[0022] In this embodiment, the sound insulation frame includes a sound insulation body, and the sound insulation body includes a transverse base 6 and a vertical base 7 perpendicular to the transverse base 6. The vertical base 7 is arranged in the middle of one side of the transverse base 6 facing the first frame 1, and the vertical base 7 is installed between the two first arms 4; two third arms 8 are arranged in parallel and at intervals in the middle of one side of the transverse base 6 facing the second frame 2, and the two third arms 8 are respectively provided with first mounting bases 9 in directions away from each other. In order to improve the sound insulation performance here, an auxiliary sound insulation groove is formed between the transverse base 6 and the third arm 8 and the first mounting base 9 on the corresponding side, and the auxiliary sound insulation groove is filled with sound insulation cotton or a second sound insulation substrate made of sound insulation cotton is installed. 10. The cross section of the second sound insulation substrate 10 is T-shaped. The sound insulation cotton or the second sound insulation substrate 10 here can assist in enhancing the sound insulation effect. At the same time, the area here is compatible with the glass installation position 3, that is, after the glass is installed, it can be designed to conflict with the sound insulation cotton or the second sound insulation substrate 10. In this way, the secondary sound noise generated by the vibration of the glass after being impacted by sound waves can be reduced during the sound insulation process, so that the sound insulation effect can be further enhanced; in addition, in order to further enhance the sound insulation effect of the sound insulation frame itself, a plurality of silencer holes 11 are arranged on the horizontal base 6, the vertical base 7, the third arm 8 and the first installation base 9.

[0023] In order to facilitate the stable installation of the first frame 1 during assembly, first positioning grooves are respectively provided on the opposite sides of the horizontal base 6 away from the vertical base 7, and second mounting bases 12 are respectively provided at the ends of the two first arms 4 facing the horizontal base 6 in directions away from each other, and the second mounting base 12 is provided with a first positioning plug 13 adapted to the first positioning groove at the corresponding position.

[0024] In order to facilitate the stable installation of the second frame body 2 during assembly, the two first mounting bases 9 are sequentially and spaced apart with a first positioning block 14 and a second positioning block 15 in a direction away from each other, and a second positioning groove for installing the second support arm 5 at the corresponding position is formed between the adjacent first positioning blocks 14 and the second positioning blocks 15 and the corresponding first mounting bases 9. At the same time, third positioning grooves are correspondingly provided on the opposite sides of the first positioning blocks 14 on the two first mounting bases 9, and support arms 16 parallel to and spaced apart from each other are provided on the second frame body 2 between the two second support arms 5. The ends of the two support arms 16 away from the second frame body 2 are bent 90 degrees in a direction away from each other and are provided with a second positioning plug-in block 17. The second positioning plug-in block 17 is inserted in the corresponding third positioning groove. The cooperation between the support arm 16 and the second support arm 5 can better enhance the installation stability of the second frame body 2.

[0025] In this embodiment, in addition to the above-mentioned method of enhancing the sound insulation effect, interconnected through holes can be provided in the transverse base 6 and the vertical base 7, and the through holes of the transverse base 6 are connected to the area between the third arms 8, and the area between the third arms 8 is connected to the area between the two support arms 16. In this way, the through holes of the transverse base 6, the through holes of the vertical base 7, the area between the third arms 8, and the area between the two support arms 16 can be filled with sound insulation cotton or a first sound insulation substrate 18 made of sound insulation cotton can be installed, so that the sound insulation effect is better improved.

[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
