Sound-proof door

Abstract

The invention discloses a sound-proof door. The sound-proof door comprises hinges and door frame seal strips. A sealing chamber is arranged on the portion, on the inner side of the angle of a door clamping groove, of a door frame body, and a sealing opening of each sealing chamber is positioned at the angle of the corresponding door clamping groove. The end faces of a plurality of frame body sound-proof columns which are connected in series extends out of the sealing openings to be located in the door clamping grooves. An L-shaped included angle formed in the periphery of the inner side of a door body forms a groove, a sound-proof chamber is arranged on the portion, at the inner side of each groove angle, in the door frame body, and an opening of each sound-proof chamber is positioned at the groove angles; and the end surfaces of a plurality of door body sound-proof blocks connected in series extend out of the openings to be located in the door clamping grooves. After the door body isclosed, two magnetic strips are mutually attracted, and each magnetic sealing strip forms a first sealing to seal a door gap. The corresponding faces of the door body sound-proof blocks and the framebody sound-proof columns are mutually abutted under the action of respective springs. According to the sound-proof door, three sealing lines are used for realizing sealing sound insulation of the doorgaps, and the sound-proof door has the advantages of being reasonable in structural design, light in weight, easy to open and close, good in sealing and sound insulation effect, long in service lifeand low in preparation cost.

Description

technical field [0001] The invention belongs to a soundproof door. Background technique [0002] In order to maintain the sound insulation effect of the traditional soundproof door, cement is injected into the door body, so that the door body is thick, inconvenient to open and close, and the hinge is easily damaged, but the sound insulation effect is not ideal, mainly because there is a gap between the door body and the door frame. For this reason, rubber sealing strips are often used to seal the gap around the door body. However, because the width of the gap between the periphery of the door body and the door frame is different, and the repeatedly extruded rubber sealing strip is easily broken and damaged, the sealing and sound insulation effect of the soundproof door is still not good. Contents of the invention [0003] The purpose of the present invention is to provide a soundproof door, which uses three sealing lines to realize the sealing and soundproofing of the doo...

For this reason, rubber sealing strips are often used to seal the gap around the door body.

However, due to the different widths of the gap between the door body and the door frame and the repeated extrusion of the rubber sealing strip is easily broken and damaged, the sealing and sound insulation effect of the soundproof door is still not good
