[0019] As Figure 1-2As shown in the figure, an invisible threshold with sound insulation and sealing functions is provided below the sound insulation door 10. A sealing strip 20 is embedded at the bottom of the sound insulation door 10. The sealing strip 20 can move downward horizontally in the closed state of the door to seal the bottom of the sound insulation door 10. The invisible threshold includes a bottom plate 30 and two heightening plates 40 stacked side by side thereon. The bottom plate 30 and the two heightening plates 40 are both flat plate structures. The bottom plate 30 is placed flat on the support below the sound insulation door 10. The two heightening plates 40 are arranged along the thickness direction of the sound insulation door 10, and a groove 50 is formed therebetween. The groove 50 is arranged directly below the sealing strip 20, and its width W3 is greater than or equal to the width W4 of the sealing strip 20.

[0020] Further, the width W1 of the bottom plate 30 is greater than the width W2 of the sound insulation door 10. One end of it extends to the outside of the sound insulation door 10, and the other end is located directly below the end of the sound insulation door 10 or extends to its outside; the opposite ends of the two heightening plates 40 are flush with the two ends of the bottom plate 30 respectively.

[0021] Further, the depth D1 of the groove 50 is between 2 mm and 5 mm; the thickness D2 of the bottom plate 30 is between 1 mm and 3 mm.

[0022] Further, the bottom plate 30 and the two heightening plates 40 are both metal plates.

[0023] In this embodiment, a slidable sealing adjustment member 60 is installed inside the bottom of the sound insulation door 10. A sealing strip 20 is provided at the bottom end of the sealing adjustment member 60. The width of the sealing adjustment member 60 is greater than the width W3 of the groove 50; the sealing strip 20 is an elastic sealing strip, and its bottom end is arc-shaped.

[0024] When the sound insulation door 10 is closed, an electronic induction device or a mechanical control device controls the sealing adjustment member 60 to drive the sealing strip 20 to move downward and closely adhere to the bottom of the groove 50 for sound insulation and sealing. The sealing adjustment member 60 at the bottom of the sound insulation door is a basic structural component of a concealed sound insulation door, which belongs to the prior art, and its specific structure will not be elaborated here.

[0025] When the ground / support platform below the sound insulation door 10 has good flatness, the upper ends of the bottom plate 30 and the heightening plate 40 placed flat thereon and the bottom of the groove 50 (i.e., the upper end of the bottom plate 30) all have good flatness. The sealing strip 20 presses against the upper end of the bottom plate 30 to block the groove 50. At the same time, the sealing adjustment member 60 presses against the upper ends of the two heightening plates 40. The overall contact surface has good flatness, ensuring the sound insulation effect. When the flatness of the ground / support platform below the sound insulation door 10 is insufficient, the bottom plate 30 forms a platform with good flatness on the ground / support platform, supports the heightening plate 40 and the groove 50 on a platform with good flatness. The sealing adjustment member 60 presses against the two heightening plates 40, and the sealing strip 20 blocks the groove 50. Each structural member cooperates with each other to form a sealed sound insulation area with a relatively narrow width (the same as the width of the sealing adjustment member 60) in the middle of the bottom end of the sound insulation door, ensuring the sound insulation effect.

[0026] By providing the bottom plate 30 and the two heightening plates 40, the utility model can form a flat platform at the bottom of the recessed sound insulation door 10 when the bottom plate / support platform below the recessed sound insulation door 10 is uneven. Cooperating with the sealing adjustment member 60 and the sealing strip 20 on the sound insulation door 10, a sealed sound insulation area with the same width as the sealing adjustment member 60 can be formed in the middle of the bottom end of the sound insulation door 10 when the sound insulation door 10 is closed, achieving the purpose of ensuring the sound insulation effect. The overall structure is simple, facilitating production and construction, and can meet the needs of installing sound insulation doors and ensuring the sound insulation effect in most construction sites.

[0027] The above does not impose any limitation on the technical scope of the utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
