Description

Technical Field

[0001] This utility model relates to the field of composite door technology, and in particular to a composite assembled soundproof wooden door. Background Technology

[0002] In modern society, noise pollution is becoming increasingly serious. Traffic noise and neighborhood noise can negatively impact people's quality of life. Therefore, people often use soundproof composite wood doors to reduce noise pollution. Currently, choosing composite wood doors filled with sound-absorbing foam is a relatively economical option. It is low-cost, and the foam's bubble structure provides effective sound insulation, offering good value for money.

[0003] However, during long-term use, especially in environments with large temperature variations, the air bubbles in the sound-insulating foam filling of this type of soundproof wooden door may expand or contract. For example, in high-temperature environments, the air inside the bubbles expands, which may cause the bubble walls to thin or even rupture; in low-temperature environments, the bubbles contract, which may cause the bubble structure to deform.

[0004] When the bubble structure is disrupted, the sound propagation path within the material changes. The mechanism by which sound energy is reduced through multiple reflections and scattering within the bubbles is weakened, resulting in a significant decrease in sound insulation. Therefore, while this type of soundproof wooden door is more economical than other types (such as composite wooden doors filled with polyurethane foam), its sound insulation performance will significantly decrease with long-term use.

[0005] Therefore, this application provides a composite assembled soundproof wooden door to solve this technical problem. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a composite assembled soundproof wooden door to solve the problem that in the existing economical soundproof wooden door, the low-cost soundproof foam filling material is structurally deformed and damaged over a long period of time, which affects the soundproofing effect.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A composite assembled soundproof wooden door includes a wooden door body, with multiple soundproof core panels horizontally inserted into the side of the wooden door body. A spring is installed at one end of each soundproof core panel inserted into the wooden door body. A fixing through hole is provided at the top of the wooden door body, and a positioning post for vertically penetrating the soundproof core panel is inserted into the fixing through hole. A filling cavity is provided in the middle of each soundproof core panel, and a base plate for holding soundproof foam is inserted into the filling cavity.

[0009] Optionally, one end of the sound insulation core board inserted into the wooden door body is fixed with multiple fixing posts, and one end of the spring is fixed to the fixing posts, while the other end abuts against the interior of the wooden door body.

[0010] Optionally, the end of the sound insulation core plate away from the spring is provided with a snap-fit ​​groove.

[0011] Optionally, the sound insulation core board has grooves symmetrically formed on both sides, and the grooves form a cavity for sound insulation within the wooden door body.

[0012] Optionally, a plurality of honeycomb holes are formed on the inner wall of the groove.

[0013] Optionally, the top of the sound insulation core board has an opening that communicates with the filling cavity.

[0014] Optionally, a gripping part is fixed to the top of the base plate, and the upper end surface of the gripping part is horizontally flush with the upper end surface of the sound insulation core board.

[0015] Optionally, a large trough for holding sound-insulating foam is provided on one side of the base plate, and a partition is provided in the large trough to divide the large trough on the side of the base plate into multiple small troughs.

[0016] Optionally, multiple positioning posts are provided, and they are hinged end to end to form a long post that vertically penetrates all the sound insulation core panels, and the side of the sound insulation core panel is provided with a positioning through hole for the long post to vertically penetrate.

[0017] Optionally, a screw cap is fixed to the top of the positioning post, and the inner wall of the upper port of the fixing through hole is provided with a thread that mates with the screw cap.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects:

[0019] In the above solution, by setting up a sound insulation core board and a base plate, the sound insulation effect can be maintained by replacing the sound insulation foam inside the base plate during long-term use, thereby extending the service life.

[0020] In the above solution, thanks to the spring and the cooperation between the positioning post and the positioning through hole, after the positioning post is pulled out, the spring can automatically pop out part of the sound insulation core board from the side of the wooden door body, so that the sound insulation core board can be pulled out to replace the sound insulation foam.

[0021] In the above solution, thanks to the multi-section design of the positioning column, the positioning column can be bent when it is pulled out, which makes it easier to operate in a space-constrained indoor environment.

[0022] In summary, this device is simple to operate and easy to use. The sound insulation foam can be replaced later by disassembly and reassembly, thus extending its service life. Attached Figure Description

[0036] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a composite assembled soundproof wooden door, including a wooden door body 1. A hinge is provided on one side of the wooden door body 1, and a lock cylinder 2 is installed in the middle of the other side. The lock cylinder 2 is fitted with a door handle 201. Two soundproof core plates 3 are also horizontally inserted into the side of the wooden door body 1 where the lock cylinder 2 is located. The two soundproof core plates 3 are located at the upper and lower positions of the lock cylinder 2, respectively.

[0037] Two fixing posts 302 are fixed at one end of the sound insulation core board 3 inserted into the wooden door body 1. Each fixing post 302 is equipped with a spring 303. The spring 303 abuts against the inner side wall of the wooden door body 1, so that the other end of the sound insulation core board 3 can pop out a part from the side of the wooden door body 1.

[0039] Meanwhile, a large trough for holding sound-absorbing foam is provided on one side of the base plate 6. The large trough is equipped with dividers 601, which divide the large trough on the side of the base plate 6 into multiple smaller troughs. Therefore, sound-absorbing foam can be easily and quickly filled into the large trough on the side of the base plate 6.

[0040] In addition, in coordination Figure 4 As shown, the top of the wooden door body 1 has a fixing through hole 101, and a positioning post 7 for vertically penetrating the sound insulation core board 3 is inserted into the fixing through hole 101. In this embodiment, multiple positioning posts 7 are provided, and they are hinged end to end to form a long post that vertically penetrates all the sound insulation core boards 3. The side of the sound insulation core board 3 has a positioning through hole 304 for the long post to vertically penetrate. The top of the positioning post 7 is fixed with a screw cap 701, and the inner wall of the upper port of the fixing through hole 101 is provided with a thread that mates with the screw cap 701.

[0041] The working principle of the technical solution provided by this utility model is as follows:

[0042] This composite assembled soundproof wooden door, when in use, by setting up a soundproof core board 3 and a base plate 6, makes it convenient to maintain the soundproofing effect by replacing the soundproofing foam inside the base plate 6 during long-term use, thereby extending its service life. Furthermore, due to the setting of the spring 303 and the cooperation between the positioning post 7 and the positioning through hole 304, after the positioning post 7 is pulled out, the spring 303 will automatically pop out part of the soundproof core board 3 from the side of the wooden door body 1, so as to remove the soundproof core board 3 for replacement of the soundproofing foam.

[0043] Meanwhile, when the positioning column 7 is pulled out, its multi-section design allows it to bend, making it easy to operate in a confined indoor space.

[0044] In summary, this device is simple to operate and easy to use. The sound insulation foam can be replaced later by disassembly and reassembly, thus extending its service life.
