A folding hook structure is used for enabling a first object and a second object which can rotate relative to each other to be in an unfolded state or a folded state, and the folding hook structure comprises a shell which is fixed to the first object and at least partially accommodates other components of the folding hook structure; the rotating disc is fixed to a second object and can be arranged in the shell in the mode of rotating around a rotating center relative to the shell, and a folding hook groove is formed in the disc face of the rotating disc. Each folding hook groove comprises a circumferential section extending in the circumferential direction of the rotating disc with the rotating center as the circle center and a radial section extending in the radial direction of the rotating disc from the circumferential section. And the folding hook is arranged in the shell and can move between a locking position and a releasing position in the radial direction of the rotating disc, and the folding hook is inserted into the folding hook groove. In the locking position, the folding hook is clamped in the radial section of the folding hook groove; and in the release position, the folding hook can slide along the circumferential section of the folding hook groove.
一种收合钩结构,用以使能够相对旋转的第一物件和第二物件处于展开状态或收折状态,收合钩结构包括:壳体,固定到第一物件,且至少部分地容置收合钩结构的其它部件;旋转盘,固定到第二物件,且能相对于壳体围绕一旋转中心旋转地设置在壳体中,旋转盘的盘面上开设有一收合钩槽,收合钩槽包括以旋转中心为圆心在旋转盘的一圆周方向上延伸的周向段和自周向段沿着旋转盘的径向方向延伸的径向段;收合钩,设置在壳体中,且设置为能沿着旋转盘的径向方向在一锁定位置与一释放位置之间移动,收合钩插设在收合钩槽中。在锁定位置中,收合钩卡合在收合钩槽的径向段中;在释放位置中,收合钩能沿着收合钩槽的周向段滑动。
