Abstract: A folding door structure is provided. The folding door structure includes an upright column, upper sliding bracket and a lower sliding bracket. The upright column is hinged to the door leaves. The folding door structure further includes a first lock component. The first lock component includes a first latch mounted inside the upright column, and both ends of which are extended out from the top and bottom of the upright column to insert into the upper slide and/or the lower slide. By providing a first lock component and an upright column, a first latch can lock the position of the upright column relative to a door frame in a direction of wind pressure. Accordingly, the stress environment of the upper sliding bracket and the lower sliding bracket is improved, and the reliability and the resistance to high wind pressure of the connection mounting structure between adjacent door leaves are improved.
