Description

Technical Field

[0001] The present application relates to the technical field of wooden doors, and in particular to a soundproof and silent wooden door. Background Art

[0002] Noise is a sound with chaotic changes in high pitch and intensity, which sounds discordant. It is produced by irregular vibrations. Any sound that interferes with people's normal rest, study and work is noise. The most direct harm of noise to the human body is hearing damage, which then acts on the central nervous system of the brain, causing headaches, insomnia, memory loss and other neurasthenia problems, so soundproof doors have appeared.

[0003] The door panels of soundproof doors are mainly made of new galvanized steel plates, and the interior uses professional sound insulation materials, damping sound insulation panels, sound insulation cotton, etc. as sound insulation fillers. However, the sound insulation effect of traditional soundproof doors, which use sound insulation cotton as sound insulation fillers in the door core, is not ideal. With the improvement of social and economic levels, the original soundproof doors have become increasingly unable to meet the needs of consumers. Utility Model Content

[0020] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0021] The present application embodiment discloses a soundproof and silent wooden door. Figure 1 and Figure 2A soundproof and silent wooden door includes a door leaf, wherein the door leaf includes a door core 1 and a door frame 2, the door core 1 is installed in the door frame 2, and a buffer layer 4 is provided at the connection between the door core 1 and the door frame 2, and the buffer layer 4 is provided as a rubber pad, so that when the door leaf is hit during the opening and closing process, the connection between the door core 1 and the door frame 2 is not easily damaged due to vibration. The door core 1 is hollow, and in order to improve the sound insulation effect of the door core 1, a plurality of honeycomb panels 3 are provided in the cavity of the door core 1, and the length direction of the honeycomb panels 3 is consistent with the height direction of the door core 1, so that after the noise passes through the door core 1 and enters the cavity of the door core 1, the honeycomb panels 3 can absorb and reduce the noise, thereby reducing the intensity of the noise penetrating the door core 1. Since the door core 1 is hollow, in order to further improve the compression resistance of the door core 1, the honeycomb panel 3 is tilted in the cavity of the door core 1, and the two side walls of the honeycomb panel 3 are respectively fixedly connected to the inner walls of the opposite sides of the cavity of the door core 1. Multiple honeycomb panels 3 are arranged along the width direction of the door core 1, and two adjacent honeycomb panels 3 and the inner wall of the cavity of the door core 1 are enclosed together to form a triangular prism-shaped hole. According to the stability principle of the triangle, the inner walls on both sides of the door core 1 are not easy to deform under the support of multiple honeycomb panels 3, and the compression strength of the door core 1 is also guaranteed while improving the sound insulation effect of the door core 1.

[0022] To further improve the sound insulation effect of the door core 1, refer to Figure 2 and Figure 3 A plurality of sound insulation panels 5 are installed on the inner wall of the cavity of the door core 1. A sound insulation panel 5 corresponds to a hole formed by two adjacent honeycomb panels 3. The sound insulation panel 5 is stably bonded to the inner wall of the cavity of the door core 1 by sealant. A mounting hole is provided on the honeycomb panel 3 along its length direction. The mounting hole of the honeycomb panel 3 is filled with sound insulation cotton 7. The honeycomb holes 9 on the honeycomb panel 3 are arranged perpendicular to the sound insulation cotton 7, so that the noise is absorbed by the honeycomb holes 9 on the honeycomb panel 3 and then blocked by the sound insulation cotton 7 again, thereby further improving the sound insulation effect of the door core 1.

[0023] In order to improve the noise reduction effect of the honeycomb panel 3, refer to Figure 3 and Figure 4 The angle between two adjacent honeycomb panels 3 is set to an acute angle, so that after the noise penetrates the side wall on one side of the door core 1, it reaches the honeycomb panel 3 and is reflected back and forth between the two honeycomb panels 3 set at an acute angle, so that the noise can be absorbed by the honeycomb panel 3 multiple times. The honeycomb hole 9 on the honeycomb panel 3 is set to a trumpet hole shape, and the aperture of the honeycomb hole 9 close to the sound insulation cotton 7 is smaller than the aperture of the honeycomb hole 9 away from the sound insulation cotton 7, so that more noise can pass through the honeycomb hole 9 and be silenced by the honeycomb hole 9. At the same time, a threaded groove 10 is arranged on the inner wall of the honeycomb hole 9. The setting of the threaded groove 10 allows the noise to be reflected and absorbed multiple times when it reaches the honeycomb hole 9, and can also improve the silencing effect of the honeycomb panel 3 to a certain extent.

[0024] Since the honeycomb panel 3 may resonate after being impacted by noise, Figure 2 A damping pad 8 is arranged between the connection between the side wall of the honeycomb panel 3 and the inner wall of the cavity of the door core 1. The setting of the damping pad 8 can effectively reduce the noise generated by the collision between the vibration of the honeycomb panel 3 and the inner wall of the cavity of the door core 1, and to a certain extent also ensures the sound insulation and silencing effect of the door core 1.

[0025] Considering that the door core 1 is hollow, in order to improve the thermal insulation of the door core 1, refer to Figure 2 The holes of the door core 1 are filled with insulation blocks 6, which not only improve the insulation effect of the door core 1, but also improve the compressive strength of the door core 1 and extend the service life of the door core 1.

[0026] The implementation principle of a soundproof and silent wooden door in the embodiment of the present application is as follows: first, the door core 1 is processed and formed to form a hollow door core 1. Then, the sound insulation board 5 and the damping pad 8 are bonded to the inner wall of the door core 1; then, the sound insulation cotton 7 is installed in the installation hole of the honeycomb panel 3, and multiple honeycomb panels 3 are installed and fixed in the cavity of the door core 1, so that the honeycomb panel 3 is pressed against the damping pad 8, and two adjacent honeycomb panels 3 and the inner wall of the cavity of the door core 1 are enclosed together to form a triangular prism-shaped hole; finally, the insulation block 6 is filled into the hole. After the assembly and forming of the door core 1 is completed, the door core 1 is installed in the door frame 2 to form a door leaf.

[0027] When the noise penetrates the side wall of one side of the door core 1 and reaches the sound insulation board 5, the sound insulation board 5 isolates the noise to a certain extent, so that only a part of the noise enters the cavity of the door core 1. Then the noise entering the cavity of the door core 1 is reflected back and forth between the two honeycomb panels 3 set at an acute angle, and is fully absorbed by the honeycomb holes 9 on the honeycomb panels 3, so that the noise is further weakened; the weakened noise penetrates the honeycomb holes 9 and is further isolated by the sound insulation cotton 7 in the honeycomb panels 3, thereby greatly reducing the volume of the noise penetrating the door core 1.

[0028] 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.
