The invention relates to an umbrella rib honeycomb structure, umbrella ribs and an umbrella. The umbrella rib honeycomb structure can be applied to the umbrella ribs and the umbrella, and comprises alower honeycomb and a first limiting part, an elastic part with fixed axial position and realizing the opening and closing function is arranged on the outer wall of the lower honeycomb, and when the lower honeycomb upwards moves to a preset position, the elastic part is triggered by the first limiting part to be opened and closed for realizing locking; the lower honeycomb is provided with a movable part, the movable part can perform axial movement within the preset journey along the lower honeycomb, and the synchronous movement of the lower honeycomb is controlled outside the preset journey; and a triggering part is arranged on the movable part, and the triggering part can trigger the elastic part for realizing unlocking when the movable part moves within the preset journey. When the improved honeycomb structure is applied to the umbrella, the operation is safer and more reliable, the injuries to hands can be basically avoided, meanwhile, holes do not need to be formed in the umbrellaribs, so that the strength of the umbrella ribs is guaranteed, and compared with the simple concave-convex mode, the honeycomb structure provided in the technical scheme has the advantage that the locking effect is stable and reliable.
