The present invention relates to a safety apparatus for a quick coupler. According to the present invention, without forming a lip part on a fixed hook, a structure of a locking device in which a coupling status of a first attachment pin and the quick coupler fixed hook can be safely maintained is operated in conjunction with an operation of a cylinder which operates a hitch after the fixed hook and the attachment pin for heavy equipment are assembled. A locking or unlocking combination is thus possible. As a result, the structure is improved so that a plate is moved in the oblique direction to easily perform the locking coupling of the fixed hook. The safety apparatus for the quick coupler of the present invention comprises: the fixed hook (110); the hitch (120); and a locking means (330).
본 발명은 제1어태치먼트 핀과 퀵 커플러 고정훅의 결합상태를 안전하게 유지시킬 수 있는 록킹장치의 구조를 고정훅에 립부위를 형성시키지 않고도 고정훅과 중장비용 어태치먼트 핀 조립 후에 히치를 동작시키는 실린더의 동작과 연계 동작되어 록킹 또는 언록킹 결합시킬 수 있도록 함으로써, 플레이트를 사선방향으로 이동시켜 고정훅의 록킹 결합이 간편하게 이루어지도록 그 구조가 개선된 퀵 커플러용 안전장치에 관한 것이다.
