It is designed in this way that outside rainwater or other liquids cannot directly enter the door, and a corner sealing surface is provided to ensure reliable sealing.

The sealing strip II has an extended flash edge, which can further prevent external rainwater or other liquids from directly entering the door.

A sealing strip III is respectively arranged on the upper and lower sides of the door leaf. The sealing strip III is perpendicular to the sealing strip I. The cross section of the sealing strip III is triangular, and the end close to the sealing strip I is a vertex. The sealing strip III III is integrated with sealing strip I to further enhance its sealing effect.

The sealing strip I is plane or W-shaped in cross-section, and the peak is arc-shaped.

A compression type door lock is arranged on the upper and lower ends of the door leaf II near the edge.

There are also n door leaves between the door leaf I and the door leaf II, where n is a positive integer greater than or equal to 1.

A bearing is installed in the shaft hole of the pivot seat, and the rotating shaft is installed in the bearing hole.

Bearings are installed on the sliding shaft.

The outer surfaces of the door leaf I and the door leaf II are provided with handles.

Beneficial effects: the utility model can realize folding and reliable sealing, and can be applied to occasions with limited space and sealing requirements.
