The invention discloses a locking mechanism of a forklift portal frame. The locking mechanism comprises a locking mechanism shell, a ball, a rectangular chute, a booster, a one-way pressure sensing catch, a ball retreating groove and a semi-circular-ring-shaped ball duct, wherein the movement of a portal-frame lock catch is limited by change of gaps among the portal-frame lock catch, the ball, the locking mechanism shell and the like, thus locking and unlocking of the forklift portal-frame are realized, and the technical problems of low bearing capacity, easy wear, difficult processing, high cost, poor reliability and small application range existing in the existing locking mechanism are solved. Compared with the prior art, the locking mechanism has the advantages of high bearing capacity, simple structure, simple processing, high reliability and the like.
