In summary, an embodiment of the present invention provides an arc door, including an arc door frame 100, a flexible film 200, a rolling mechanism 300, and two tension guide mechanisms 400, where the arc door frame 100 includes an upper rail 110, a lower rail 120, and a vertical rod 130, two ends of the vertical rod 130 are respectively connected to one side of the upper rail 110 and one side of the lower rail 120, two ends of the rolling mechanism 300 are respectively connected to the other side of the upper rail 110 and the other side of the lower rail 120, the two tension guide mechanisms 400 are symmetrically disposed at two ends of the rolling mechanism 300, and the two tension guide mechanisms 400 are respectively rotatably connected to the upper rail 110 and the lower rail 120; the flexible film 200 is wound around the winding mechanism 300, both upper and lower sides of the flexible film 200 are slidably connected to the upper rail 110 and the lower rail 120, respectively, and free ends of the two tension guide mechanisms 400 are connected to the movable side of the flexible film 200 along the inside of the upper rail 110 and the lower rail 120, respectively. In this embodiment, the upper rail 110 and the lower rail 120 are made of aluminum alloy sections, and have C-shaped cross sections, and are bent to form the outer periphery of the arc-shaped door/window. The tension guide mechanism 400 is used to bear the lateral tension of the flexible film 200 passing through the bent portions of the upper and lower rails 110 and 120. When the door needs to be closed, a user pulls the movable side of the flexible film 200 to enable the flexible film 200 to slide along the upper guide rail 110 and the lower guide rail 120, and when the door passes through the bending part of the upper guide rail 110 and the lower guide rail 120, the tensile force on the flexible film 200 can be borne by the two tensile force guide mechanisms 400, so that the flexible film 200 is in a loose state, the flexible film 200 can easily pass through the bending part, collapse is avoided, the stable forming of the structure of the arc-shaped door is realized, and the complete opening and closing of the interior of the arc-shaped door frame 100 can be realized through the bending and stretching of the flexible film 200.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
