Abstract

The invention relates to an air-tight door sealing element structure which comprises a sealing element structure body (1), a doorframe (2) and door leaves (3), wherein the sealing element structure body (1) is mounted on the doorframe (2); the sealing element structure further comprises an outer sealing ring (101), an inner sealing ring (102), a sealing groove seat (103) and screws (104); the sealing groove seat (103) is further provided with sealing grooves for allowing the outer sealing ring and the inner sealing ring to be disassembled and assembled, and is fixed on the doorframe (2) through the screws (104); the outer sealing ring (101) and the inner sealing ring (102) all adopt hollow structures; the outer sealing ring (101) and the inner sealing ring (102) are tightly pressed by a pressing device between the doorframe (2) and the door leaves (3). According to the air-tight door sealing element structure, the double sealing rings are pressed and fixed on a bottom groove seat in an embedded manner, and the bottom groove seat is tightly fixed on the doorframe, so that an integrated air tight device is formed, standardized production is facilitated, the consistency is good, and disassembly, assembly and maintenance are convenient. The air-tight door sealing element structure has better economic benefits and a good air-tight effect.

Description

technical field [0001] The invention relates to an airtight door and its seal structure, belonging to the technical field of airtight doors. Background technique [0002] The airtight door is a special door that can meet the airtight performance requirements. The common method is a single-layer bowl-shaped bell-mouth-shaped sealing strip, which is pasted on the door frame, which is easy to wrinkle, deform and fall off. It is inconvenient to replace and the airtight effect is not good. Ideal; in addition, the processing technology at the corner of the bowl-shaped bell-shaped sealing strip is complicated, and the manufacturing is troublesome and difficult. Contents of the invention [0003] The technical problems to be solved in the present invention are: the existing airtight door is easy to wrinkle, deform and fall off, it is inconvenient to replace, and the airtight effect is not ideal; the processing technology at the corner of the bowl-shaped bell-shaped sealing strip i...
