[0002] Interior doors refer to the doors at the entrance of a bedroom or study room. The installation of interior doors will leave gaps at the bottom, resulting in poor sound insulation and dustproof effects.

[0003] After checking the public (announcement) number: CN219733176U, a silent seamless door silent strip installation structure is disclosed. This technology discloses "the arc-shaped protrusion is moved outward into the inner cavity of the arc-shaped hole, and the first connecting strip is limitedly installed on the door cover, and the spherical block is limited in the card groove by the block, and the second connecting strip is limitedly installed on the silent door" and other technical solutions, which have "compared with the existing method of fixing by bolts, the operation is more convenient and no tools are required for disassembly" and other technical effects;

[0004] The above scheme makes the door tighter after closing by cooperating with the silent strip one and the silent strip two, thereby improving the silent effect. However, it only solves the sound insulation problem on both sides of the door body. In daily use, there will still be gaps at the top and bottom of the door body. The conventional method is to install sound insulation strips at the ends of the door body, but the door body will cause wear of the sound insulation strips during long-term opening and closing, thereby affecting the sound insulation effect after closing the door.
