The door leaf is mainly made of new galvanized steel plates, and the interior uses professional sound insulation materials, damping sound insulation boards, sound insulation cotton, etc. as sound insulation fillers. At the same time, the most important thing for soundproof doors is sealing. The use of magnetically controlled sealing can ensure good sealing and sound insulation effects.

[0003] The commonly recommended soundproof doors are usually filled with sound-absorbing cotton or PU inside, and some are just made of cardboard to form a so-called honeycomb structure. On the one hand, it increases the strength of the door panel, and on the other hand, it uses the closed air layer formed to provide a certain degree of sound insulation. However, there is a gap between the bottom of the soundproof door and the ground, resulting in the overall sound insulation effect of the soundproof door not meeting the requirements. Some soundproof doors also have sealing strips at the bottom, but the sealing strips are difficult to clean and replace. After a long period of use, the sound insulation effect is greatly reduced.

The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] See also Figure 1 As shown, in this embodiment, a soundproof door bottom sealer is provided, which is suitable for the bottom of a door without a threshold, including a bottom cover plate 1, which is used to be installed at the bottom of the soundproof door. The bottom cover plate 1 can be an eccentric structural design or a symmetrical structural design. A profile 2 is installed in the bottom cover plate 1, and the profile 2 is used to install a seal 3. A plurality of seals 3 are provided, and a plurality of seals 3 extend from the profile 2 to the outside of the bottom cover plate 1. When the bottom cover plate 1 moves downward to fit the ground, the seal 3 is squeezed and deformed by the ground, thereby playing a sealing role and having a good sound insulation effect.

[0026] In this embodiment, the bottom cover plate 1 and the profile 2 are both made of aluminum alloy, which has a relatively low density, good thermal conductivity and good processing performance. The characteristics of aluminum alloy include: light weight: aluminum alloy has a low density; corrosion resistance: aluminum alloy has good corrosion resistance and can be used for a long time in the atmosphere and water environment without being easily rusted; good thermal conductivity: aluminum alloy has good thermal conductivity; recyclable: aluminum alloy can be recycled and reused, which is beneficial to resource recycling and environmental protection.

[0027] Specifically, a receiving cavity 11 for installing the profile 2 is provided in the bottom cover plate 1, and the receiving cavity 11 is inverted T-shape. A limiting rib 12 is provided on the upper inner wall of the receiving cavity 11. The profile 2 is inserted into the receiving cavity 11, and the profile 2 is limited by the limiting rib 12. The bottom edge of the bottom cover plate 1 is a plane, and a track is not required for installing the track.

[0028] In this embodiment, a plurality of gaskets 4 are provided in the gap between the profile 2 and the inner wall of the accommodating cavity 11 , and the profile 2 is installed in the bottom cover plate 1 by the friction between the gaskets 4 and the profile 2 to prevent the profile 2 from falling off from the bottom cover plate 1 .

[0029] In this embodiment, the gasket 4 is a graphite gasket, which is stacked with high-purity graphite sheets and has excellent high temperature resistance, corrosion resistance and good thermal conductivity. The main features of the graphite gasket include:

[0030] High temperature resistance: The graphite pad has good high temperature resistance and can be used for a long time in a high temperature environment without deformation or damage; Corrosion resistance: The graphite pad has strong corrosion resistance and can be used in chemically corrosive media without being easily corroded; Good thermal conductivity: Graphite has good thermal conductivity and can effectively conduct heat, making it suitable for occasions that require heat dissipation; Good compression elasticity: The graphite pad has certain elasticity and compression properties, and can fill uneven surfaces when sealing to ensure the sealing effect; Long life: The graphite pad has a long service life, is not easy to age or harden, and can still maintain stable performance in harsh environments.

[0031] The sealer uses a graphite pad to make the connection between the profile 2 and the bottom cover plate 1 more stable, prolonging the service life. No screws or rivets are required to fix the profile 2 and the bottom cover plate 1, which makes it easy to remove the profile 2 from the bottom cover plate 1 and clean the profile 2.

[0032] See also Figure 2 As shown, in this embodiment, the profile 2 includes a fixing portion 21 and a sealing portion 22. The profile 2 is in an inverted T shape as a whole. The fixing portion 21 is used to be inserted into the accommodating cavity 11. Gaskets 4 are arranged in the gaps between the two sides of the fixing portion 21 and the inner wall of the accommodating cavity 11. The lower end surface of the sealing portion 22 is provided with a plurality of T-shaped grooves 23 extending along the length direction of the profile 2. The T-shaped grooves 23 are used to install the seals 3. The plurality of seals 3 are installed in the T-shaped grooves 23 to avoid the seals 3 from falling off. When the seals 3 are damaged, the replacement of the seals 3 is also convenient.

[0033] See also Figure 3 As shown, in the present embodiment, the sealing member 3 comprises a mounting strip 31 and a sealing strip 32, the mounting strip 31 is in an I-shape, the upper portion of the mounting strip 31 is used to be inserted into the T-shaped slide groove 23, and after the mounting strip 31 is installed, the mounting strip 31 fits against the lower end surface of the sealing portion 22, the lower end surface of the mounting strip 31 is connected to the sealing strip 32, the sealing strip 32 is in an arc shape, the arc β of the sealing strip 32 ranges from -5° to 90°, and the angle α between the sealing strip 32 and the mounting strip 31 ranges from -90° to 165°. Through this design, the sealing strip 32 is arranged in an inclined shape at the bottom of the mounting strip 31, and is more likely to deform when the sealing strip 32 contacts the ground, and the area of ​​the deformed sealing strip 32 that contacts the ground is increased, especially when the threshold stone is not horizontal, due to the different heights of the threshold stone, the deformation degrees of the multiple sealing strips 32 in contact with the threshold stone are different, and the sealing strip 32 is closely attached to the threshold stone, so that the sealing and sound insulation effect is better.

[0034] See also Figure 4As shown, in another embodiment, a soundproof door using the above-mentioned soundproof door bottom sealer is provided, including a door bottom aluminum frame 5, a decorative panel 6 and a sound insulation layer 7, the sealer is installed on the door bottom aluminum frame 5, and the decorative panel 6 is provided with two respectively installed at the two ends of the door bottom aluminum frame 5, and a sound insulation layer 7 is provided between the two decorative panels 6.

[0035] Specifically, when the soundproof door is in use, it is suitable for situations where the threshold stone is horizontal or non-horizontal. The deformation degrees of the multiple sealing strips 32 in contact with the threshold stone are different, ensuring that the sealing strips 32 are tightly attached to the threshold stone to prevent the propagation of sound, thereby achieving better sealing and sound insulation effects. It is particularly suitable for installation in places where a lower threshold cannot be provided.
