Problems solved by technology
[0002] In the existing home life, in order to increase the comfort and safety of indoor living, we generally install fire-proof silent doors, but the existing silent doors are only thicker than ordinary doors, and then sound-proof materials or sound-absorbing materials are installed inside , this method can increase the mute effect, but the door body and the door frame will have a gap in order to be able to open. If it is set to be sealed, the door body will not be able to open relative to the door frame. Therefore, once there is a gap, the mute effect will be worse.

The invention discloses a fireproof mute door which comprises a door body mounted in the middle of a door frame. Mounting cavities are formed in the middle of the door body, and the upper end, the lower end and the left side end of the door body are each provided with a through groove. The through grooves are each internally loaded with a sealing plug, and the inner side ends of the sealing plugsstretch into the mounting cavities in the middle of the door body. A sound insulation plate is mounted in each mounting cavity, and the four faces of the outer sides of the sound insulation plates make sliding contact with the inner walls of the mounting cavities correspondingly. One or more movable-type sound insulation pieces are arranged between each sound insulation plate and the correspondingmounting cavity, and a connecting part is arranged outside each sound insulation plate. Corresponding connecting through grooves are formed in the positions, directly facing the connecting parts, ofthe door body in a penetrating mode, the connecting parts penetrate through the connecting through grooves and stretch outwards, and the stretching ends of the exteriors of the connecting parts are each connected with an external protective plate. The fireproof mute door has the very good mute effect, gaps between the four faces of the door body and the door frame are effectively sealed during using, and operation is easy.
Description
technical field [0001] The invention relates to a fireproof silent door. Background technique [0002] In the existing home life, in order to increase the comfort and safety of indoor living, we generally install fire-proof silent doors, but the existing silent doors are only thicker than ordinary doors, and then sound-proof materials or sound-absorbing materials are installed inside , this method can increase the mute effect, but the door body and the door frame will have a gap in order to be able to open. If it is set to be sealed, the door body will not be able to open relative to the door frame. Therefore, once there is a gap, the mute effect will be worse. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fireproof silent door, which has a very good mute effect and effectively seals the gaps between the four sides of the door body and the door frame when in use. [0004] The present invention is achieved...
