Bolt-assembled split-type hitch ball

Abstract

A bolt-assembled split-type hitch ball includes a bolt, where the bolt passes through a ball and a shoulder, the shoulder abuts against a lower surface of the ball, a second anti-rotation groove and a first anti-rotation groove are formed in the shoulder and the ball, respectively, and an anti-rotation key is jointly mounted in cavities of the second anti-rotation groove and the first anti-rotation groove; a spring washer abuts against a lower surface of the shoulder, the spring washer is sleeved on an outer side of the bolt, and a nut abuts against a lower surface of the spring washer; and the nut is threadedly connected to the bolt, and a retaining pin is disposed below the nut. A user only needs to prepare spare balls of different sizes to adapt to various trailer couplers, thereby avoiding the extra cost of purchasing a plurality of hitch ball assemblies.
