Description

Technical Field

[0001] This utility model relates to the technical field of door panel sound insulation equipment, and in particular to a door panel sound insulation device. Background Technology

[0002] A common door consists of a door panel and a door frame. The door and door frame work together to separate two rooms. When sound insulation is required, a soundproofing device is installed on the door panel.

[0003] For example, a soundproof door disclosed in Chinese patent application CN202121329100.0 has the following specific content: a rubber buffer strip is fixedly attached to the lower surface of the soundproof panel. When the user opens the door panel, under the pull of the spring, the moving rod drives the soundproof panel into the storage groove to reduce the impact of the soundproof panel on the movement of the door panel; when the user closes the door panel, the door frame applies a force to the arc-shaped end face of the trigger rod. At this time, the trigger block drives the moving rod to move downward, thereby completing the sealing of the gap below the door panel by the soundproof panel. However, this design has the following technical problems:

[0004] After repeated opening and closing of doors, the buffer strip is prone to wear and tear, resulting in reduced sound insulation. Since the bottom end of the moving rod passes through the sound-absorbing cotton and is fixedly connected to the sound insulation panel, it is difficult to replace the buffer strip once it wears out.
