The rotation locking device includes a rotation link 4 fixedly connected with the chair body 2 , a rotation support part 5 fixed on the base 1 and an unlocking wrench 6 arranged on the rotation link 4 . The rotating connecting rod 4 is rotatably connected to the rotating supporting part 5 and the rotating axis of the rotating connecting rod 4 extends along the left-right direction of the chair body 2 . The rotating support part 5 is provided with a plurality of locking grooves, and the unlocking wrench 6 has a locking part 61 which locks and cooperates with the locking grooves. In this embodiment, a plurality of lock slots are distributed on the rotating support portion 5 along the up-down direction of the chair body 2 , including a first lock slot 51 , a third lock slot 53 and a second lock slot 52 from top to bottom.

In this embodiment, the chair body 2 includes an annular frame rod assembly, and the rotating support part 5 is protrudingly arranged on the base 1 . The rotating connecting rod 4 is in the shape of a concave "W" in the middle. The unlocking wrench 6 is rotatably connected to the concave part on the rotating connecting rod 4 and the rotating axis of the unlocking wrench 4 is parallel to the rotating axis of the rotating connecting rod 4 . The support rod 3 is located below the chair body 2 . The support rod 3 is a concave "W" shape in the middle, and the upper ends on the left and right sides are connected to the both sides of the frame rod of the chair body 2 by rotation respectively. The left and right sides of the base 1 are respectively provided with fixed support parts 7 for supporting the support rod 3 , and the fixed support part 7 has grooves matched with the support rod 3 . In the support state, both sides of the lower part of the support rod 3 are respectively supported on the fixed support parts 7 on the left and right sides of the base and snapped into the grooves of the fixed support part 7 . When folded, both sides of the lower part of the support rod 3 can be disengaged from the grooves of the fixed support part 7 .

The chair body 2 has a supporting state and a lying down state. The angle between the chair body 2 and the base 1 in the supporting state is greater than the angle between the chair body 2 and the base 1 in the lying down state. The locking part 61 of the unlocking wrench 6 can be buckled in the first locking groove 51, the second locking groove 52 or the third locking groove 53 respectively, correspondingly, the rotating link 4 has a first locking position, a second locking position and Third locked position.
