Description

Technical Field

[0001] The utility model relates to the technical field of protective airtight doors, in particular to a single-leaf protective airtight door with a steel structure and a movable threshold. Background Art

[0002] With the development of society, more and more protective closed doors are used. Protective closed doors are set at the outermost side of the entrance and exit. Protective closed doors should be able to block shock waves and meet the corresponding resistance requirements.

[0003] The existing Chinese patent with the patent announcement number "CN209780648U" has announced "a seismic-resistant adaptive steel structure movable threshold single-leaf protective closed door". Through the electric push rod, slide groove and slider, the opening and closing of the protective closed door can be controlled by the extension and retraction of the electric push rod. Two fixing rings are fixed on the surface of the connecting rod, a worm sleeve is sleeved between the two fixing rings, and a worm wheel matching the worm sleeve is provided on the top of the worm sleeve. When the worm wheel rotates, the worm sleeve is pushed to move left and right. Under the action of the two fixing rings, the connecting rod moves left and right together, and then drives the threshold to move left and right, thereby controlling the retraction and extension of the threshold.
