Claim:
A collapsible device for a golf cart, comprising: a frame folding articulation mounted between an upper frame and a lower frame for folding the upper frame; a frame collapsing articulation mounted on a mediate portion of the lower frame for folding the lower frame; a rear wheel frame mounted between the frame collapsing articulation and at least one rear wheel; a first pull bar mounted between the frame articulation and the rear wheel frame for folding the at least one rear wheel; a front wheel folding articulation mounted between the lower frame and a front wheel frame for folding a front wheel; a second pull bar mounted between the rear wheel frame and the front wheel folding articulation; wherein the front wheel and the at least one rear wheel are folded simultaneously by linking of the first pull bar and the second pull bar; the first pull bar is connected with the upper frame and the rear wheel frame respectively; the second pull bar is connected with the rear wheel frame and the front wheel frame respectively; when a user folds the golf cart, the upper frame is driven rearward and downward to drive and push the first pull bar downward which drives the rear wheel frame to retract inward and drives the rear wheel to retract inward, and the rear wheel frame drives and pushes the second pull bar downward which drives the front wheel frame to pivot about the shaft of the bottom bracket so that the front wheel frame is moved upward and retracted inward, and the front wheel is moved upward and folded inward; the front wheel and the rear wheel are folded through a rotation motion; the front wheel is disposed above the rear wheel after the front wheel and the rear wheel are folded.
