A movable umbrella base comprises a housing (1), a wheel frame (2) disposed under the bottom of the housing (1), at least three wheels (3) connected at intervals to the wheel frame (2) and located partially under the wheel frame (2), a plurality of air bags (4) located inside a space defined by the wheel frame (2) and the housing (1), and a plurality of elastic members (6) limit displacement of the wheel frame (2) and the wheels (3) from the housing (1); when the air bags (4) are inflated, the housing (1) is lifted up relative to the wheel frame (2) and the wheels (3) from the ground; when the air bags (4) are deflated, the housing (1) is lowered relative to the wheel frame (2) and the wheels (3) and contacts the ground. The umbrella base can be moved by the air bags (4), the whole operation process is easier, and it saves more time and effort.
