Movable sunshade base

Abstract

The present disclosure relates to a movable sunshade base. The base comprises a base frame, a base cover, a roller component, a rotary assembly, a transmission component, a first drive rod, a second drive rod and a pull rod. Through swinging a pull rod, the second drive rod drives the transmission shaft, thereby driving the first drive rod. Driven by the first drive rod, a wheel bracket achieves power transmission using the leverage theorem, thereby controlling the roller to move to the outside of the base frame. When the movement is completed, the pull rod is swung to the opposite direction so that the roller can shrink into the base frame. The disclosure has the advantages of simple operation, convenient appearance, strong practicability and low cost, and can effectively solve the problem of moving difficulty and can be applied to various types of sunshade base.
