The invention belongs to the aviation cabin door technology, and particularly relates to a quick-switching hinge mechanism for a cabin door opening way. The quick-switching hinge mechanism for the cabin door opening way at least consists of two groups of hinge units which are respectively positioned at the rear side and the lower side of a cabin door. Each hinge unit comprises two fixed hinges, a movable fork lug and a quick-dismounting hinge shaft assembly, wherein the quick-dismounting hinge shaft assembly is a spring type clamping slot structure, the movable fork lug is a two-way fork lug slot, a fork lug at one side of the two-way fork lug slot is connected with a fixed hinge on a door frame by virtue of the quick-dismounting hinge shaft assembly, and the fork lug at the other side of the two-way fork lug slot is connected with a fixed hinge on the cabin door by virtue of two parallel quick-dismounting hinge shaft assemblies. According to the quick-switching hinge mechanism, the quick conversion for the cabin door opening way is realized by inserting and pulling the two quick-dismounting hinge shaft assemblies of the fixed hinge on the cabin door, the operation is extremely convenient, and all components are provided with fixing devices, so that the quick-switching hinge mechanism is safe and reliable, and required manpower and material resources are greatly reduced.
