Abstract
Description
Technical Field
[0001] This application relates to the technical field of soundproof doors, and particularly to a soundproof door. Background Art
[0002] In the architectural decoration industry, people generally use wooden doors to decorate their rooms. However, the sound insulation and sealing performance cannot reach the ideal effect, seriously affecting the sound environment of people's private spaces. Especially in public places where the noise is relatively large, soundproof doors are more needed to decorate the office space.
[0003] The current soundproof doors include door frames and soundproof door leaves. The soundproof door leaves are hinged inside the door frames, and the soundproof door leaves are soundproofed. When the soundproof door leaves are closed, the soundproof door leaves reduce the noise, thereby improving the comfort of the office or living space.
[0004] However, due to the easy error in the installation of the door leaves, there is a gap between the door leaves and the door frames when the door leaves are closed, and the door frames themselves do not reduce noise. Therefore, ultimately, the noise is transmitted through the gap and the door frames, affecting the overall sound insulation performance of the soundproof doors. Utility Model Content

Detailed implementation manners
[0034] The following further elaborates on this application Figures 1-6 in conjunction with the accompanying drawings.
[0035] Embodiment:
[0036] Refer to Figure 1 and Figure 2 , a sound-insulating door, including a door leaf 1 and a door frame 2. The door frame 2 has three sides, and the door leaf 1 is hinged inside the door frame 2. A overlapping frame 3 is fixedly connected to the inner side of the door frame 2, and the overlapping frame 3 also has three sides. When the door leaf 1 is closed, the door leaf 1 abuts against the outer side of the overlapping frame 3. The overlapping frame 3 is equipped with a first sound insulation sealing assembly for improving the sound insulation sealing performance between the door leaf 1 and the overlapping frame 3. An edge seal 4 is fixedly connected to the peripheral side of the door leaf 1, and a stepped groove 5 is formed at a position corresponding to the edge seal 4 on the outer side of the door frame 2, and the edge seal 4 is inserted into the stepped groove 5. The edge seal 4 is equipped with a second sound insulation sealing assembly for improving the sound insulation sealing performance between the edge seal 4 and the door frame 2.
[0037] When the door leaf 1 is closed, first, the door leaf 1 abuts tightly against the outer side of the overlapping frame 3, and the edge seal 4 abuts tightly in the stepped groove 5. The first sound insulation sealing assembly serves as the first seal between the door leaf 1 and the door frame 2, and the second sound insulation sealing assembly serves as the second seal between the door leaf 1 and the door frame 2, thereby improving the sound insulation sealing performance between the door leaf 1 and the door frame 2.
[0038] Specifically, refer to Figure 3 and Figure 4 , the first sound insulation sealing assembly includes a first sound insulation rubber strip 6. An embedding groove 7 is formed on the outer side of the overlapping frame 3, and the inner surface of the first sound insulation rubber strip 6 is embedded in the embedding groove 7.
[0039] Refer to Figure 4 , to further improve the sealing performance of the first sound insulation rubber strip 6 when the door leaf 1 is closed, a first wavy edge 8 is provided on the side of the first sound insulation rubber strip 6, and the first wavy edge 8 is beneficial to enhancing the deformation ability of the first sound insulation rubber strip 6. The outer surface of the first sound insulation rubber strip 6 is inclined, and the inclination angle is 15° - 30°.
[0040] When the door leaf 1 is closed, the door leaf 1 squeezes the first sound insulation rubber strip 6. Under the action of the first wave edge 8, the first sound insulation rubber strip 6 deforms. Also, since the outer surface of the first sound insulation rubber strip 6 is inclined, the deformation reaction force on the part of the first sound insulation rubber strip 6 that first contacts the door leaf 1 is greater, thereby making the sound insulation and sealing performance stronger.
[0041] Specifically, refer to Figure 5 and Figure 6 , the second sound insulation sealing assembly includes a second sound insulation rubber strip 9. A clamping groove 10 is formed on the inner side of the edge sealing 4, and the outer surface of the second sound insulation rubber strip 9 is clamped in the clamping groove 10.
[0042] Refer to Figure 6 , to further improve the sealing performance of the second sound insulation rubber strip 9 when the door leaf 1 is closed, a second wave edge 11 is provided on the side of the second sound insulation rubber strip 9. The second wave edge 11 is beneficial to enhancing the deformation ability of the second sound insulation rubber strip 9. The inner surface of the second sound insulation rubber strip 9 is inclined, and the inclination angle is 20° - 35°.
[0043] When the door leaf 1 is closed, the door leaf 1 drives the edge sealing 4 to be inserted into the stepped groove 5 and squeezes the second sound insulation rubber strip 9. Under the action of the second wave edge 11, the second sound insulation rubber strip 9 deforms. Also, since the inner surface of the second sound insulation rubber strip 9 is inclined, the deformation reaction force on the part of the second sound insulation rubber strip 9 that is first squeezed is greater, thereby making the sound insulation and sealing performance stronger.
[0044] Refer to Figure 1 and Figure 2 , to further improve the overall sealing and sound insulation performance when the door leaf 1 is closed, a threshold 12 is fixedly connected to the bottom surface of the door frame 2. A receiving groove 13 is formed in the position of the threshold 12 corresponding to the edge sealing 4, and the edge sealing 4 is inserted into the receiving groove 13. When the door leaf 1 is closed, under the action of the threshold 12, the edge sealing 4 corresponding to the bottom end of the door leaf 1 abuts against the groove wall of the receiving groove 13 at this time.
[0045] Refer to Figure 3 , to reduce the weight of the door frame 2 and improve the sound insulation performance of the door frame 2, an inner cavity 14 is provided inside the door frame 2. Filling holes 15 are formed on both inner sides of the door frame 2. The number of filling holes 15 on each side is three, and the three filling holes 15 are respectively located above, in the middle, and below the door frame 2. The filling holes 15 are communicated with the inner cavity 14, and the inner cavity 14 is filled with foaming glue.
[0046] When it is necessary to fill foaming glue into the inner cavity 14, first inject foaming glue into the upper part of the door frame 2 through the upper filling hole 15, then inject foaming glue into the middle part of the door frame 2 through the middle filling hole 15, and then inject foaming glue into the lower part of the door frame 2 through the lower filling hole 15. After the foaming glue solidifies, the foaming glue fills the door frame 2 densely. And under the action of the foaming glue, noise is reduced.
[0047] It is worth mentioning that, referring to Figure 3 , in order to prevent the foaming glue from overflowing from the filling hole 15, the filling hole 15 is blocked by a plug cover 16.
[0048] Referring to Figure 2 and Figure 5 , to improve the convenience of assembling the door leaf 1, a first hinge cylinder 17 is fixedly connected to the outer side of the door frame 2, and a second hinge cylinder 19 is correspondingly fixedly connected to the outer side of the door leaf 1. A hinge shaft 18 is inserted into the first hinge cylinder 17, and the top end of the hinge shaft 18 extends above the first hinge cylinder 17. The top end of the hinge shaft 18 is inserted into the second hinge cylinder 19.
[0049] When the door leaf 1 needs to be installed, first insert the hinge shaft 18 into the first hinge cylinder 17, and then lift the door leaf 1 so that the second hinge cylinder 19 is aligned and inserted into the hinge shaft 18. At this time, the door leaf 1 rotates around the hinge shaft 18 as the axis.
[0050] The working principle of a soundproof door:
[0051] When the door leaf 1 is closed, first the door leaf 1 abuts against the outer side of the overlapping frame 3, and the door leaf 1 squeezes the first soundproof rubber strip 6. Under the action of the first wave edge 8, the first soundproof rubber strip 6 deforms. Also, since the outer surface of the first soundproof rubber strip 6 is inclined, the greater the deformation reaction force on the part of the first soundproof rubber strip 6 that first contacts the door leaf 1, the stronger the soundproof sealing performance.
[0052] Secondly, the door leaf 1 drives the sealing edge 4 to be inserted into the stepped groove 5 and squeezes the second soundproof rubber strip 9. Under the action of the second wave edge 11, the second soundproof rubber strip 9 deforms. Also, since the inner surface of the second soundproof rubber strip 9 is inclined, the greater the deformation reaction force on the part of the second soundproof rubber strip 9 that is first squeezed, the stronger the soundproof sealing performance.
[0053] In summary, the first soundproof sealing component serves as the first seal between the door leaf 1 and the door frame 2, and the second soundproof sealing component serves as the second seal between the door leaf 1 and the door frame 2, thereby improving the soundproof sealing performance between the door leaf 1 and the door frame 2.
[0054] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
