Abstract
The utility model relates to a shock absorbing front fork for bicycles. A front fork shoulder is fixed with two piston barrels, the lower part of the piston barrel is inserted in the hollow tube of a front fork leg, and a piston ring is padded between the lower part of the piston barrel and the hollow tube of the front fork leg. The lower end surface of the piston barrel is penetrated with a piston rod. Two pressure springs with a big diameter and a small diameter are sheathed on the piston rod out of the piston barrel, and the piston rod is buckled and connected in a threaded hole on the bottom of the hollow tube of the front fork leg by threads on the lower end of the piston rod. The utility model has the advantages of reasonable design, shapely configuration, easy assembly and convenient maintenance.
