发明名称 ANTI-RATTLE TRAILER HITCH
摘要 A hitch assembly generally includes a hitch receiver that retains an insert by a pin. The pin is preferably hook-shaped and includes a primary pin segment and an engagement terminus. The primary pin segment defines a primary axis transver se to the common longitudinal axis of the hitch assembly. When assembled, the primary segment passes through an aperture located in a first wall of the hitch receiver, th e insert aperture of the insert and another aperture in the second wall of the hitch receiver. As a fastener is threadably engaged with a threaded portion of the pin, the fastener pulls the primary pin segment through the hitch receiver and drives the engagement terminus through the second aperture against the insert. The fastener thereby introduces tension in the pin to restrict movement of the insert relative to the hitch receiver and minimize free-play therebetween. In one embodiment, a tamper resistant secondary retainer provides a lock which engages a conical end of the pin.
