LOCKING DEVICE FOR LOCKING OUTRIGGER IN ENGINEERING MACHINERY

摘要

A locking device for locking an outrigger in engineering machinery comprises a housing (1) having a limited chamber inside and having a left end provided with an opening (10); a latch (2) disposed in the chamber, capable of moving between a first position and a second position in a left/right direction, and provided with a protruding shoulder(21) arranged at a predetermined distance away from a left end thereof, wherein when in the first position, the left end of the latch extends out of the chamber from the opening and the protruding shoulder abuts against a left side wall of the chamber, and when in the second position, the left end of the latch retracts into the chamber; an elastic member (3) sleeving the latch and pressing the protruding shoulder in a leftward direction in a biased manner; and a driving assembly (5), the driving assembly being used for driving the latch to move from the first position to the second position. The locking device is capable of reducing labor intensity and is reliable in locking.
