Abstract
The utility model discloses a portable omni-directional movable jack capable of lifting, moving and rotating weights, which is convenient in carrying.The jack comprises a framework part, a lifting mechanism and a moving mechanism.According to the framework part, a device matrix is formed by fixed connection of two shoe plates, a mobile shaft, a middle shaft and a large wheel shaft.According to the lifting mechanism, a small piston rod is driven to move up and down by the up and down shaking of a lever.Based on the Pascal principle, the big piston in the cylinder driven by the oil pressure pushes the crane arm and the object-supporting wheels thereon via the big piston rod, so that the weight is lifted.Two sets of mutually independent and symmetrical secondary chain transmission mechanisms are adopted by the moving mechanism, wherein one is from left sprockets to middle sprockets and the other is from the middle sprockets to right sprockets.The right sprockets are fixedly connected with the object-supporting wheels and the left sprockets are connected with a bidirectional ratchet wrench.The up and down shaking of the lever operated by hands drives the two left sprockets and the object-supporting wheels to rotate.The rotation directions of the two object-supporting wheels are independently controlled by a reversing dial block, which are the same or the opposite.Therefore the weight is driven to move or rotate, thereby realizing the omni-directional movement of the weight.
