Anti-loose structure of elastic sleeve pin coupling

Abstract

The utility model discloses a kind of elastic sleeve pin coupling anti-loosening structure, including coupling main body one, and coupling main body two by pin main body installation on coupling main body one, nut is threadedly connected on the pin main body, oblique through-port is set up on the pin main body, be provided with inclined surface block in the oblique through-port, the side surface of inclined surface block is pressed on nut.The utility model is through the cooperation of coupling main body one, pin main body, coupling main body two, nut, oblique through-port, inclined surface block, shaft sleeve one, shaft sleeve two, elastic sleeve body, gasket, outer thread and stabilizing ring, realize a kind of elastic sleeve pin coupling anti-loosening structure, utilize inclined surface block tightly plug into oblique through-port, extrude nut, then, utilize stabilizing ring to limit the position of each inclined surface block, can avoid inclined surface block from oblique through-port and separate, can effectively avoid that nut is reversed on the surface of pin main body, can effectively prevent from detaching, guarantee the stability of coupling connection.
