AI Technical Summary

Technical Problem

The hinged door structure of the soundproof cabin causes gaps between the door leaf and the door frame, affecting the sound insulation effect and reducing the sound insulation performance.

Method used

The magnetic soundproof door with a double airtight structure increases the contact area by setting the first and second magnetic components at an angle. It uses magnetic attraction to make the door leaf and the door frame fit tightly together, and the sealing strip abuts against the positioning part to reduce gaps and enhance airtightness and sound insulation.

Benefits of technology

The airtightness and sound insulation of the silent cabin door have been improved, the gap between the door leaf and the door frame has been reduced, and the door's sealing and quietness performance has been enhanced.

Abstract

This utility model discloses a double-airtight magnetic soundproof door suitable for a soundproof cabin, comprising: a door frame and a door leaf; the door frame has an opening, and a positioning part is provided on the inner side of the opening, with a first magnetic component installed in the positioning part, the first magnetic component being inclined; the door leaf matches the opening and is hinged to the door frame, with a sealing element provided on the edge of the door leaf, and a second magnetic component and a sealing strip surrounding the sealing element, the second magnetic component being inclined, so that when the door leaf is closed in the opening, the second magnetic component and the first magnetic component attract each other, and the sealing strip abuts against the positioning part. The inclined nature of both the first and second magnetic components increases their contact area, enhances their attraction, ensures a secure closure of the door leaf and door frame, and ensures the sealing strip adheres tightly to the positioning part, reducing gaps between the door leaf and door frame and improving sound insulation.
