as shown in fig. 4, the first member 1 and the second member 3 are relatively rotated to move the locking member 5 toward the second end of the arc-shaped elongated hole 311 until the second protrusion 313 enters the groove 51 of the locking member 5 toward the second protrusion and pushes the locking member 5 to rotate for a second time (for example, the rotation direction is counterclockwise in fig. 4), so that one end of the locking member 5 away from the second protrusion 313 abuts against the edge of the arc-shaped elongated hole 311, at this time, the locking member 5 is changed from the pre-locking state to the locking state, and the first member 1 and the second member 3 cannot relatively rotate to move the locking member 5 toward the second end of the arc-shaped elongated hole 311;
as shown in fig. 5, the first member 1 and the second member 3 are relatively rotated to move the locking member 5 toward the first end of the arc-shaped elongated hole 311, when the locking member 5 reaches the first end of the arc-shaped elongated hole 311 again, the first protrusion 312 pushes the locking member 5 to rotate for the third time (taking fig. 5 as an example, the rotating direction is counterclockwise), at this time, the locking member 5 is changed from the locking state to the unlocking state, and the first member 1 and the second member 3 can relatively rotate to move the locking member 5 toward the second end of the arc-shaped elongated hole 311;
as shown in fig. 6, the first member 1 and the second member 3 are rotated relative to each other to move the locking member 5 toward the second end of the arc-shaped elongated hole 311, and in the process, the second protrusion 313 pushes the locking member 5 to rotate for a fourth time (in the example of fig. 6, the rotation direction is counterclockwise), so that the two recesses 51 respectively correspond to the first end and the second end of the arc-shaped elongated hole 311, and the locking member 5 is switched to the pre-locking state again.
Based on the characteristics, the hinge assembly can be used for a cabinet to hinge the movable panel 8 and the cabinet body 7, and the first part 1 and the second part 3 can rotate relatively, so that the movable panel 8 can be switched between a spreading state and a folding state through overturning; because the relative rotation between the first component 1 and the second component 3 can drive the locking piece 5 to switch between the unlocking state, the pre-locking state and the locking state, the hinge assembly can not only lock the movable panel 8 in the unfolding state, so that the movable panel is stable and reliable when being used as a dining table, a desk, a bar counter and the like, but also does not influence the smooth folding of the movable panel 8; in addition, the hinge assembly has the advantages of simple structure, low production cost, difficult damage and the like.

Alternatively, as shown in fig. 1, the two grooves 51 have the same structure, and are symmetrical with respect to the axial center of the second shaft member 4. Thus, even if the lock member 5 is reversed by 180 ° every time it passes through one cycle (from the unlocked state to the pre-locked state, and back to the unlocked state after the locked state), the next cycle is not affected.
Alternatively, as shown in fig. 1, in order to allow the first and second protrusions 312 and 313 to enter the groove 51 more smoothly, the groove 51 is preferably a V-groove.
Optionally, the first component 1, the second component 3 and the support 6 are all hardware, and have the advantages of high strength, high rigidity, low cost, good durability and the like; the locking piece 5 is made of rubber to obtain better locking capacity.
