The inner frame plate is located on the rear side of a front frame, a gap is formed between the innerframe plate and the outer frame plate, the peripheral size of the inner frame plate is smaller than that of the outer frame plate, the inner periphery of the inner frame plate is connected with the inner periphery of the outer frame plate through the annular connecting plate, and the inner frame plate abuts against the outer surface of the glass. The part, located on the outer side of the inner frame plate, of the outer frame plate abuts against the surface of the door body and is fixed through a positioning part. Compared with the prior art, the fireproof door is more convenient to install,the wrapping strips are more tightly combined with the surface of the glass, the gap between the glass and the pane is sealed in the wrapping strips, a sound transmission path can be separated by a sealing space formed by the wrapping strips, and the sound insulation performance of the fireproof door is improved.

    本发明公开了一种设置有观察窗的防火门,包括门体,门体上设置有窗格,窗格的侧壁设置有密封减震块,窗格内设置有边缘与密封减震块抵接的玻璃,门体的两侧向窗格内安装有包条,包条包括内框板、外框板和环状连接板,内框板位于前框后侧并与外框板之间设置有间隙,内框板的外周尺寸小于外框板外周尺寸,内框板内周与外框板内周通过环状连接板进行连接,内框板与玻璃外表面抵接,外框板位于内框板外侧的部分与门体表面抵接并通过定位部进行固定。相对于现有技术而言,安装更为方便,包条与玻璃表面结合更为紧密,而且将玻璃与窗格之间的间隙密封在包条内,使声音传递的路径会被包条所形成的密封空间隔断,使防火门的隔音性能提升。
