AUTOMATIC CARGO LOADING HOOK, AND LOCK MECHANISM

PROBLEM TO BE SOLVED: To provide an automatic cargo loading hook capable of automatically locking and releasing rotation of a hooker. SOLUTION: In a constitution in which a hooker 4 is pivotally attached between right and left fork parts 2B, 2C of a frame 2, a rack gear 8 is inwardly formed at a left upper part of the hooker 4, a lock body 9 having an inward rack gear 11 is rotatably disposed at a right upper part of the hooker 4, a pinion gear 13 is disposed to be rotated by a motor 12 to be engaged with both rack gears 8, 11, so rotation directions of the hooker 4 and the lock body 9 are reversed by rotation of the pinion gear 13, a tip part of a stopper 6 rotatably suspended at an upper back part of the hooker 4 is engaged with a step part 5 in the hooker 4 and a lock groove in the lock body 9 to stop rotation of the hooker 4, the lock body 9 is rotated counterclockwise to release the stopper 6 by right rotation of the pinion gear 13, and the hooker 4 is rotated clockwise to push up the tip part of the stopper 6 for stopping the motor 12 in this automatic cargo loading hook 1.
