The invention discloses an armrest lock structure and a seat. A ratchet wheel (100) is provided with inner teeth, and the inner circumference of the ratchet wheel is provided with a concave section and a convex section; the locking cam (102) is connected with a seat armrest (003); the reset spring (103) is connected with the sliding groove plate (101) and the locking cam (102). The sliding block (104) is installed in the first sliding groove of the sliding groove plate (101) and provided with a first protruding part and outer teeth. At the initial position, the first convex part is positioned on the concave section, and the outer teeth are meshed with the inner teeth; in the first working section, the seat armrest (003) only rotates in one direction, and the sliding block (104) slides along the outline of the inner teeth and gradually gets close to the protruding section. In the second working section, the first convex part abuts against the convex section, the outer teeth are separated from the inner teeth, the locking part locks the locking cam (102) and the sliding groove plate (101), and the seat armrest (003) can rotate bidirectionally; the unlocking portion enables the armrest lock structure to return to the initial position. The adjusting device is high in adjusting precision and locking strength and more reliable.
