Please refer to fig. 1 to 9. One embodiment of the present utility model provides a hinge for a folding door, which includes a rotation shaft 1, a first sheet 2, a first spacer 3, a second sheet 4, and a second spacer 5. The first sheet 2 is rotatably arranged on the rotating shaft 1. The first gasket 3 is arranged on the first sheet 2. The second leaf 4 is rotatably arranged on the rotating shaft 1. The second gasket 5 is arranged on the second sheet 4.

The rotating shaft 1 comprises a shaft body 11 and a rotating shaft sleeve 12, and the two rotating shaft sleeves 12 are respectively arranged at two ends of the shaft body 11. The rotating shaft sleeve 12 prevents the first sheet 2 and the second sheet 4 from being separated from the shaft body 11, and ensures the stability of the sheets.

Specifically, the inner side of the first sheet 2 is provided with an opening 21, the second sheet 4 includes a shaft connection portion 41 and a gasket connection portion 42, the shaft connection portion 41 is connected with the rotating shaft 1, the gasket connection portion 42 is connected with the shaft connection portion 41 through a bearing portion 43, the shaft connection portion 41 and the gasket connection portion 42 are located on different planes, the shaft connection portion 41 and the bearing portion 43 are matched with the opening 21 of the first sheet 2, and the shaft connection portion 41 and the bearing portion 43 can penetrate through the opening 21 of the first sheet 2 in the rotating process.

Specifically, the first sheet 2 is provided with two first shaft sleeve portions 22, and the two first shaft sleeve portions 22 are sleeved at two ends of the shaft body 11. The second leaf 4 is provided with a second sleeve part 44, the second sleeve part 44 is sleeved at the middle part of the shaft body 11, the second leaf 4 is sleeved at the middle part of the shaft body 11, and the whole hinge is stable in structure.
