The invention relates to the field of roller shutter door equipment, in particular to an airtight roller shutter door. The airtight roller shutter door comprises curtain cloth, a door frame, a winding roller, a driving roller and a driving device serving as a power source. The winding roller is in synchronous transmission connection with the driving roller, and the curtain cloth is wound on the winding roller in a rollable mode. Chain teeth extending along the side parts of the curtain cloth are arranged on the two transverse sides of the curtain cloth, chain wheels matched with the chain teeth are arranged on the two axial sides of the driving roller, the curtain cloth makes contact with the driving roller when being wound or unwound, and the chain teeth at the two transverse ends of the curtain cloth are in meshed transmission with the chain teeth on the chain wheels. A sliding groove for the curtain cloth to slide up and down is formed in the end face of the inner side of the door frame, an air bag which extends along the sliding groove and is used for sealing is embedded in the sliding groove, and after the air bag is inflated, the air bag enables the two sides of the curtain cloth to abut against the interior of the sliding groove to form a sealing structure in the door frame. According to the technical scheme of the airtight roller shutter door, the problem that an existing roller shutter door sealing structure is insufficient in stability is solved.
本发明涉及卷帘门设备领域，具体涉及一种气密卷帘门，包括帘布、门框、收卷辊、驱动辊以及作为动力源的驱动装置，所述收卷辊与驱动辊同步传动连接，所述帘布可卷曲的收卷在所述收卷辊上，所述帘布的横向两侧设置有沿其侧部延伸的链齿，所述驱动辊的轴向两侧设有与所述链齿适配的链轮，帘布在收卷/放卷时与所述所述驱动辊相接触，帘布横向两端的链齿与链轮上的链牙相啮合传动,所述门框的内侧端面开设有用于帘布上下滑动的滑槽，所述滑槽内嵌置有沿所述滑槽延伸的密封用的气囊，当所述气囊充气后，气囊将所述帘布的两侧抵靠在所述滑槽内形成门框内的密封结构。本技术方案解决了现有的卷帘门密封结构稳定性不足的问题。
