Soundproof door

Abstract

The invention discloses a soundproof door. The soundproof door comprises door leaves and door pockets movably connected with the door leaves, wherein an air bag is arranged on one side, opposite to the floor, of each of the door leaves; an air pump is arranged in the door pockets, and the air inlet and air outlet of the air bag are connected with the air outlet of the air pump; a door lock is also arranged on the door leaves, the door lock comprises a first spring bolt and a second spring bolt, also comprises a counter lock connected with the second spring bolt; a second spring bolt box is arranged on the door pockets, the second spring bolt is placed in the second spring bolt box, and an air pump switch contact in contact with the second spring bolt is arranged in the second spring bolt box. The soundproof door has the advantages that the sealing property is good, the service life is long, the structure is simple, the fabrication cost is low, and the maintenance is easy.

Description

technical field [0001] The invention relates to a wooden door, in particular to a soundproof door. Background technique [0002] The interior door structure is assembled by door casing, door leaf and hardware accessories. The gap between the door leaf and the door casing is mostly sealed with rubber strips, but there is no sealing measure for the gap between the door leaf and the ground. The interior of the door leaf of the existing soundproof door is provided with a mezzanine, the rotating shaft of the handle is located in the mezzanine, and the interlayer is provided with a rotating rod, a push rod, a spring and a sound insulation board. The middle part of the rotating rod is movably connected to the rotating shaft of the handle, and the two ends are respectively connected Push the rod, the top of the push rod is connected to the sound insulation board through the spring, and the top of the sound insulation board protrudes from the interlayer and snaps into the groove at t...

AI Technical Summary

Problems solved by technology

The bonding performance between the sound insulation panel and the bottom surface of this kind of soundproof door is not good, and noise and light can still enter the room from the gap between the sound insulation panel and the ground, which cannot provide residents with a quiet and private living environment, and the sealing is still not enough it is good

At the same time, the spring in the interlayer is prone to elastic fatigue under long-term working conditions, which makes the transmission efficiency of the push rod and the sound insulation board poor, which in turn leads to poor adhesion between the sound insulation board and the ground, and the sealing performance will decline or even fail after a period of use. short life

In addition, this kind of soundproof door also has the characteristics of complex structure, high production cost and difficult maintenance.
