Bicycle folding shock-absorption front fork

The utility model discloses a folding shock-absorption bicycle front fork. The whole rigidity and intensity are not impacted by a folding mechanism, the folding can be completed conveniently and rapidly, and also the function of shock absorption can be realized. The folding suspension front fork is composed of a stand pipe, a crown, an upper branch pipe, a sleeve pipe, an upper installation board, a lower branch pipe, a lower installation board, an operation rod, an upper moving bolt, a lower moving bolt, an upper spring stop pin, a lower spring stop pin, a folding shaft, a shock-absorption device and the like. The sleeve pipe is sleeved on the upper branch pipe. The sleeve pipe is equipped with the upper installation board. The lower branch pipe is provided with the lower installation board. The upper installation board and the lower installation board are in hinge joint via the folding shaft. At the time of folding, the operation rod is rotated to enable the upper moving bolt and the lower moving bolt inside the upper branch pipe to stretch out-of-step, then the upper spring stop pin and the lower spring stop pin stretch correspondingly, and thus the upper branch pipe can be withdrew from the lower branch pipe and located. The lower branch pipe rotates around the folding shaft, and the folding of the front fork is realized. At the time of unfolding and riding, the lower branch pipe is convoluted around the folding shaft, the operation rod is convoluted, and the upper branch pipe can be inserted into the lower branch pipe and located. The shock absorption device is installed inside the lower branch pipe, and the shock absorption function of the front fork can be realized.
