EXPLOSION-PROOF TIRE HUB, EXPLOSION-PROOF TIRE, AND MOVING TOOL

Disclosed are an explosion-proof tire hub, including a hub body and an explosion-proof convex retainer. The hub body includes bent portions configured to mount a vacuum tire, the hub body is provided with a central axis, the explosion-proof convex retainer is fixed on the hub body, the distance between an upper end of the explosion-proof convex retainer and the central axis is L the distance between an upper end of the bent portion and the central axis is L and L is greater than L In case of burst or instantaneous pressure loss, because the distance L between the upper end of the explosion-proof convex retainer and the central axis is greater than the distance L between the upper end of the bent portion and the central axis, the explosion-proof convex retainer reduces the distance between the whole hub and the ground during tire burst and improves safety performance.
