The invention discloses a combined type locking washer. The combined type locking washer comprises a clamping gasket fixed to the outer wall of a screw rod, and a supporting ring; a first clamping grain is formed in the outer wall of the top of the clamping gasket; an upper gasket is welded to the outer wall of the top of the supporting ring; a lower gasket is welded to the outer wall of the bottom of the supporting ring; a second clamping grain is formed in the outer wall of the bottom of the lower gasket; convex blocks are welded to the outer wall of the top of the upper gasket and the outerwall of the bottom of the lower gasket; a first alloy connector is welded to the inner wall of one side of the upper gasket; and a clamping groove is formed in the side, away from the convex blocks,of the first alloy connector. Through cooperation of the clamping gasket and the threaded gaskets, vertical vibration and lateral horizontal movement are prevented, the washer can achieve the lockingfunction, vertical reinforcement ribs and an annular clamping ring can improve the strength of the combined type locking washer, the combined type locking washer is not squashed, the slip phenomenon during bolt screwing is prevented through cooperation of the clamping grains of the gaskets, the whole bolt structure is locked, and through matching of high-strength clamping blocks of the alloy connector, lateral movement or breakage is avoided.
