Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-4 This is the first embodiment of the present invention, which provides a multi-layered building soundproof window, including...

[0023] A window frame 1 has a window sash 3 hinged to its front surface. The window sash 3 can be opened and closed, and opening the window sash 3 achieves the effect of ventilation.

[0024] The sealing and soundproofing device includes an extension frame 33 installed on the rear surface of the window sash 3, which adds the extension frame 33; a second EPDM multi-cavity soundproofing strip 5 bonded to the outer side of the extension frame 33, which securely installs the second EPDM multi-cavity soundproofing strip 5; a recess 11 opened on the window frame 1, which adds the recess 11; and multiple first EPDM multi-cavity soundproofing strips 4 installed on the recess 11 and tightly fitted with the second EPDM multi-cavity soundproofing strip 5, which adds the first EPDM multi-cavity soundproofing strips 4. The stabilizing component, with the third EPDM multi-cavity sound insulation strip 9 tightly attached to the second EPDM multi-cavity sound insulation strip 5, achieves the addition of the third EPDM multi-cavity sound insulation strip 9. When the window sash 3 is closed, the first EPDM multi-cavity sound insulation strip 4 and the third EPDM multi-cavity sound insulation strip 9 are tightly attached to the second EPDM multi-cavity sound insulation strip 5, forming an effective sound barrier to prevent sound from entering the room from the connection between the window sash 3 and the window frame 1. The good sealing not only provides sound insulation but also improves the thermal insulation performance of the window and reduces the exchange of heat between the indoor and outdoor areas.

[0025] In this embodiment, preferably, the stabilizing component includes a fastening seat 7 installed on the recess 11, which realizes the addition of the fastening seat 7, a fastening plate 8 detachably connected to the fastening seat 7, and a third EPDM multi-cavity sound insulation strip 9 installed on the fastening plate 8, which increases the support for the third EPDM multi-cavity sound insulation strip 9.

[0026] In this embodiment, preferably, fasteners 82 are symmetrically arranged on the side surface of the fastening plate 8, which realizes the addition of fasteners 82. The fasteners 82 have an "L" shaped structure and are installed on the fastening seat 7 by screws, which helps to achieve the stability of the fastening plate 8 and the fastening seat 7 splicing. The fastening plate 8 can be disassembled and replaced when the third EPDM multi-cavity sound insulation strip 9 is worn.

[0027] In this embodiment, preferably, a second double-glazed glass 31 is installed on the inner side of the window sash 3 to increase sound insulation performance. A fastening frame 2 is installed on the window frame 1 to realize the addition of the fastening frame 2. A first double-glazed glass 21 is installed on the inner side of the fastening frame 2 to increase sound insulation performance. A notch 51 is opened on the side surface of the second EPDM multi-cavity sound insulation strip 5 to realize the opening of the notch 51. A symmetrically distributed connecting block 510 is installed on the inner side of the notch 51 to realize the addition of the connecting block 510. A pull rod 6 is provided on the two connecting blocks 510. When the surface of the second EPDM multi-cavity sound insulation strip 5 is worn, the cooperation of the connecting block 510 and the pull rod 6 increases the convenience of removing and replacing the second EPDM multi-cavity sound insulation strip 5.

[0028] EPDM, or ethylene propylene diene monomer rubber, has excellent weather resistance, which can resist the erosion of natural factors such as ultraviolet rays, ozone, wind and rain for a long time and is not easy to age and crack. It also has good chemical corrosion resistance and strong resistance to chemicals such as acids, alkalis and salts. In addition, it has good elasticity and can maintain good flexibility under different temperature environments, effectively buffering vibration and impact.

[0029] The multi-cavity structure is the key feature of this type of adhesive strip. By setting multiple independent cavities inside the adhesive strip, these cavities can block the transmission of sound. When sound enters, it will be continuously reflected and refracted in the cavity, consuming sound energy, thereby achieving a better sound insulation effect.

[0030] EPDM multi-cavity sound insulation strips are installed in soundproof areas and can fit tightly into gaps to prevent sound from directly entering the room or vehicle through the gaps, forming a physical sound barrier. The cavity structure causes sound to encounter obstacles during propagation, and it is reflected and refracted multiple times within the cavity. The sound energy is gradually consumed and attenuated in this process, thereby reducing the intensity of sound propagation.

[0031] Example 2

[0032] Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0033] The fastening plate 8 is provided with a limiting block 81, which realizes the addition of the limiting block 81. The fastening seat 7 is provided with a limiting groove 71 for the limiting block 81 to be inserted. When the fastening plate 8 and the fastening seat 7 are spliced, the limiting block 81 is inserted into the inside of the limiting groove 71, and the inner side of the limiting groove 71 is provided with a stop bar 710 that can abut against the limiting block 81. When the limiting block 81 is inserted into the inside of the limiting groove 71, the limiting block 81 abuts against the inner side of the two stop bars 710, which has a reinforcing effect. One end of the stop bar 710 is inclined, and a handle 32 is installed on the front surface of the window sash 3 to increase the convenience of opening the window sash 3.

[0034] The working principle and usage process of this utility model: When ventilation is needed, hold the handle 32 on the front surface of the window sash 3 and pull it outward to open the window sash 3 and realize the circulation of indoor and outdoor air;

[0035] When it is necessary to isolate external noise, maintain a quiet indoor environment and a good thermal insulation environment, push the handle 32 to close the window sash 3; at this time, the second EPDM multi-cavity sound insulation strip 5 on the outer side of the extension frame 33 on the rear surface of the window sash 3 will be tightly attached to the first EPDM multi-cavity sound insulation strip 4 on the recess 11 of the window frame 1 and the third EPDM multi-cavity sound insulation strip 9 installed on the fastening plate 8, forming an effective sound barrier to prevent sound from entering the room from the connection between the window sash 3 and the window frame 1, while reducing the exchange of heat between the indoor and outdoor areas and improving thermal insulation performance;

[0036] If a decrease in sound insulation is found, and it is determined after inspection that the third EPDM multi-cavity sound insulation strip 9 is worn, the screws on the fastener 82 can be unscrewed with a screwdriver or other tools to remove the fastening plate 8 from the fastening seat 7, and the third EPDM multi-cavity sound insulation strip 9 installed on the fastening plate 8 can be replaced; after replacement, the fastening plate 8 can be reinstalled on the fastening seat 7 using the fastener 82, and it should be ensured that the limiting block 81 is accurately inserted into the limiting groove 71 and the stop strip 710 is pressed against the limiting block 81;

[0037] If the surface of the second EPDM multi-cavity sound insulation strip 5 is found to be worn during inspection, the second EPDM multi-cavity sound insulation strip 5 can be removed from the outer side of the extension frame 33 by pulling the pull rod 6 and using the action of the connecting block 510 for replacement. After replacement, the second EPDM multi-cavity sound insulation strip 5 should be re-adheded and installed to ensure that it is installed firmly and in the correct position so that it can be tightly bonded to the first EPDM multi-cavity sound insulation strip 4 and the third EPDM multi-cavity sound insulation strip 9 in the future.

[0038] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
