Technical Field

[0001] The utility model relates to the technical field of door and window sound insulation, in particular to a sound insulation structure for doors and windows. Background Art

[0002] Traffic noise in cities continues to bother the general public. To address this, many families choose to install double-glazed doors and windows. The vacuum chamber between the double-glazed windows provides better sound insulation and thermal insulation than ordinary doors and windows.

[0003] Existing soundproof doors and windows are mainly composed of door frames, double-layer glass installed in the door frames, a vacuum soundproof cavity arranged between the double-layer glass and the door frames, and sound insulation materials filled in the door frames. Although doors and windows of this structure have good sound insulation performance when in use, the sound insulation materials in the frame are prone to corrosion and damage over time. Since the sound insulation materials in the soundproof doors and windows of the above structure are mainly fixed and installed by bonding, the efficiency of replacing and repairing the sound insulation materials when they are corroded and damaged in the later stage is relatively low, which is not convenient for efficient inspection and maintenance of the doors and windows in the later stage. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a sound insulation structure for doors and windows in response to the current status of the existing technology, which can realize efficient replacement of sound insulation materials in the frame when they are corroded and damaged by pulling and plugging, and is convenient for efficient inspection and maintenance of doors and windows in the later stage.

[0005] The present invention is achieved through the following technical solution: The present invention proposes a sound insulation structure for doors and windows, comprising a frame, two sound insulation components symmetrically installed on one side wall of the frame, and two limiting components respectively installed on both side walls of the frame facing the sound insulation components. The sound insulation component comprises a U-shaped pull plate, a connecting column installed on the U-shaped pull plate facing the side wall of the frame, a sound insulation board installed at one end of the connecting column facing away from the U-shaped pull plate, sound insulation foam wrapped around the outside of the connecting column, and sound insulation felt installed on the side of the sound insulation board facing away from the connecting column. The limiting component comprises a spring installed on the frame, a pull cap installed on the end of the spring facing away from the frame, and a limiting column installed in the middle of the pull cap. A limiting groove is also provided on the U-shaped pull plate facing the connecting column.

[0006] By adopting the above technical solution, the sound insulation felt, the sound insulation board and the sound insulation foam in the sound insulation assembly are pushed into the frame during use, and then the limiting column in the limiting assembly is inserted into the limiting groove in the U-shaped pull plate, thereby realizing effective limiting of the sound insulation assembly in the frame. When the sound insulation material in the sound insulation assembly is corroded and damaged, it is only necessary to pull the connecting column in the limiting assembly out of the limiting groove in the U-shaped pull plate, and then the sound insulation assembly can be conveniently pulled out of the frame for maintenance.

[0007] Furthermore, a drawing groove is provided on the outer wall of the U-shaped drawing plate, and a concave structure is formed in the drawing groove.

[0008] By adopting the above technical solution, the pulling of the U-shaped pull plate can be made more convenient with the help of the pull groove.

[0009] Furthermore, the frame body is hollow in structure at locations opposite to the connecting column and the limiting groove, and the limiting column passes through the spring and is welded to the pull cap.

[0010] By adopting the above technical solution, it can be ensured that the limiting column passes through the side wall of the frame body and is inserted into the limiting groove conveniently.

[0011] Furthermore, the sound insulation foam is bonded to the U-shaped pull plate, the connecting column and the sound insulation board, and the sound insulation felt is bonded to the sound insulation board.

[0012] By adopting the above technical solution, the sound insulation foam is a high-density sound insulation material, which can effectively block noise. The connecting column can effectively increase the reliable installation of the sound insulation foam between the sound insulation board and the U-shaped pull plate. The sound insulation felt can further improve the overall sound insulation performance of the door and window.

[0013] Furthermore, an inner layer of glass is installed on one side of the frame, an outer layer of glass is installed on the other side of the frame, and a vacuum sound insulation cavity is reserved between the inner layer of glass and the outer layer of glass in the frame.

[0014] By adopting the above technical solution, the frame, the inner layer of glass and the outer layer of glass constitute the main structure of the door and window, ensuring the normal installation and use of the door and window.

[0015] Furthermore, sealing strips are installed in the frame on both sides of the inner glass and on both sides of the outer glass.

[0016] By adopting the above technical solution, the sealing strip can effectively seal the gap between the inner layer of glass and the outer layer of glass after installation.

[0017] Furthermore, the sealing strip is made of rubber, and the sealing strip is bonded to both the inner layer of glass and the outer layer of glass.

[0018] By adopting the above technical solution, it is possible to ensure that the sealing strip is reliably installed and fixed on both sides of the inner glass and the outer glass, and to ensure the sealing performance of the sealing strip.

[0019] Furthermore, an air extraction hole is provided on the frame above the vacuum sound insulation cavity, and a sealing plug is installed at the port of the air extraction hole.

[0020] By adopting the above technical solution, the vacuum sound insulation cavity can be evacuated into a vacuum state through the exhaust hole under the action of external vacuum equipment, and the sealing plug can prevent external air from entering the vacuum sound insulation cavity, thereby ensuring good sound insulation performance of the vacuum sound insulation cavity.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The utility model reserves a groove on the door frame and installs a sound insulation component consisting of a U-shaped pull plate, sound insulation foam, sound insulation board, connecting column and sound insulation felt in the groove in a sliding and plug-in manner. At the same time, a limiting component consisting of a limiting column, a pull cap and a spring is used to limit the installed sound insulation component. When the sound insulation material in the sound insulation component is corroded and damaged, the limiting column in the limiting component can be pulled out of the limiting groove on the U-shaped pull plate, so that the sound insulation component can be conveniently withdrawn and replaced from the frame, effectively improving the replacement and maintenance efficiency of the sound insulation material in the sound insulation doors and windows, and facilitating the efficient inspection and maintenance of the sound insulation doors and windows in the later stage.

[0030] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figure 1 、 Figure 3 and Figure 4 As shown, a sound insulation structure for doors and windows in this embodiment includes a frame 1, two sound insulation components 2 are symmetrically installed on one side wall of the frame 1, and two limiting components 3 are respectively installed on the two side walls of the frame 1 facing the sound insulation components 2. The sound insulation component 2 includes a U-shaped pull plate 202, a connecting column 201 installed on the U-shaped pull plate 202 facing the side wall of the frame 1, a sound insulation board 204 installed at the end of the connecting column 201 facing away from the U-shaped pull plate 202, a sound insulation foam 203 wrapped around the outside of the connecting column 201, and a sound insulation felt 205 installed on the side of the sound insulation board 204 facing away from the connecting column 201. The limiting component 3 includes a spring 302 installed on the frame 1, a pull cap 303 installed on the end of the spring 302 facing away from the frame 1, and a limiting column 301 installed in the middle of the pull cap 303. A limiting groove 221 is also provided on the U-shaped pull plate 202 facing the connecting column 201.

[0032] The embodiment of the present invention provides a sound insulation structure for doors and windows that can realize efficient replacement of the sound insulation material in the frame 1 when it is corroded and damaged by pulling out and plugging, which is convenient for efficient inspection and maintenance of doors and windows in the later stage. It solves the problem that the sound insulation material in the frame 1 of the existing sound insulation doors and windows is easily corroded and damaged over time, and because the sound insulation material in the existing sound insulation doors and windows is mainly fixed and installed in a bonding manner, the replacement and maintenance efficiency of the sound insulation material when it is corroded and damaged in the later stage is relatively low, which is not convenient for efficient inspection and maintenance of doors and windows in the later stage. The overall idea of ​​the embodiment of the present invention to solve the above problem is: the sound insulation felt 205, the sound insulation board 204, and the sound insulation board 205 in the frame 1 are connected to the sound insulation board 204. The foam 203 is combined together under the action of the connecting column 201 and the U-shaped pull plate 202 to form a sound insulation component 2, and a groove for installing the sound insulation component 2 is reserved in the frame 1. At the same time, a limiting component 3 consisting of a limiting column 301, a spring 302 and a pull cap 303 is installed in the frame 1, which is opposite to the limiting groove 2021 on the U-shaped pull plate 202 in the sound insulation component 2. This not only facilitates the convenient installation of the sound insulation component 2 in the frame 1, but also when the sound insulation material in the sound insulation component 2 is corroded and damaged, the limiting column 301 in the limiting component 3 is pulled out of the limiting groove 2021 on the U-shaped pull plate 202, thereby realizing the convenient extraction and replacement of the sound insulation component 2 from the frame 1.

[0033] like Figure 1-Figure 3 As shown, in this embodiment, a pull groove 2022 is further provided on the outer wall of the U-shaped pull plate 202. The pull groove 2022 has a concave structure. The pull groove 2022 enables the U-shaped pull plate 202 to have more strength parts when being pulled, thereby making it easier to pull the U-shaped pull plate 202.

[0034] like Figure 3-Figure 5 As shown, in this embodiment, the connection column 201 and the limiting groove 2021 on the frame 1 are both hollow structures, and the limiting column 301 passes through the spring 302 and is welded to the pull cap 303, which can ensure that the limiting column 301 can easily pass through the side wall of the frame 1 and be inserted into the limiting groove 2021. The spring 302 is in a stretched state when the pull cap 303 is pulled outward. After the sound insulation component 2 is installed in the frame 1, it is only necessary to loosen the pull cap 303 to realize the automatic insertion of the limiting column 301 into the limiting groove 2021 under the action of the spring 302.

[0035] like Figure 2-Figure 3 As shown, in this embodiment, the sound insulation foam 203 is bonded to the U-shaped pull plate 202, the connecting column 201 and the sound insulation board 204, and the sound insulation felt 205 is bonded to the sound insulation board 204. The sound insulation foam 203 is a high-density sound insulation material. The sound insulation foam 203, the sound insulation board 204 and the sound insulation felt 205 cooperate to make the soundproof doors and windows have three kinds of sound insulation performance, effectively preventing external noise from entering the room through the frame 1, so that the sound insulation effect of the doors and windows is better.

[0036] like Figure 2 As shown, in this embodiment, an inner layer of glass 5 is installed on one side of the frame 1, and an outer layer of glass 8 is installed on the other side of the frame 1. A vacuum sound insulation cavity 9 is reserved between the inner layer of glass 5 and the outer layer of glass 8 in the frame 1. The frame 1, the inner layer of glass 5 and the outer layer of glass 8 constitute the main structure of the door and window, ensuring the normal installation and use of the door and window.

[0037] like Figure 2 As shown, in this embodiment, sealing strips 4 are installed on both sides of the inner glass 5 and the outer glass 8 in the frame 1. The sealing strips 4 can effectively seal the gap between the inner glass 5 and the outer glass 8 after installation to ensure that the external air does not enter the vacuum sound insulation cavity 9 after the vacuum is evacuated in the vacuum sound insulation cavity 9. The sealing strips 4 are made of rubber and are bonded to the inner glass 5 and the outer glass 8, which can ensure that the sealing strips 4 are reliably installed and fixed on both sides of the inner glass 5 and the outer glass 8, and ensure the sealing performance of the sealing strips 4.

[0038] like Figure 2 As shown, in this embodiment, an exhaust hole 7 is further provided on the frame 1 above the vacuum sound insulation cavity 9, and a sealing plug 6 is installed at the port of the exhaust hole 7. The vacuum sound insulation cavity 9 can be evacuated into a vacuum state through the exhaust hole 7 under the action of an external vacuum pumping device, and the sealing plug 6 can prevent external air from entering the vacuum sound insulation cavity 9, thereby ensuring good sound insulation performance of the vacuum sound insulation cavity 9.

[0039] The specific implementation process of this embodiment is as follows: when in use, first push the sound insulation felt 205, sound insulation board 204 and sound insulation foam 203 in the sound insulation component 2 into the frame 1, and then insert the limiting column 301 in the limiting component 3 into the limiting groove 2021 in the U-shaped pull plate 202 to achieve effective limitation of the sound insulation component 2 in the frame 1, and then just install the frame 1 at the reserved installation position in the indoor wall, so that the soundproof door and window can be put into use. During use, when the sound insulation material in the sound insulation component 2 is corroded and damaged, just pull out the connecting column 201 in the limiting component 3 from the limiting groove 2021 in the U-shaped pull plate 202, and then the sound insulation component 2 can be conveniently pulled out of the frame 1 for maintenance, which effectively improves the replacement and maintenance efficiency of the sound insulation material in the sound insulation door and window, and facilitates the efficient inspection and maintenance of the sound insulation door and window in the later stage.
