The invention belongs to the technical field of baby carriage accessories. Specifically, the present invention relates to a movable joint capable of being rotated and locked. The movable joint comprises a first connecting piece and a second connecting piece, and further comprises a movable limiting device, the movable limiting device is connected between the first connecting piece and the second connecting piece, and the movable limiting device generates axial displacement during rotation so as to achieve the rotation and locking of the second connecting piece. The movable joint capable of being rotated and locked has two states. When in use, the joint is in a supporting state, and when in storage, the joint is in a storage state. When the joint is applied to a baby carriage, unlocking canbe achieved by rotating the movable limiting device, the baby carriage is convenient to store, a button does not need to be pressed during unlocking, a user can exert force easily, and the operationdifficulty can be lowered; and moreover, the torsion applied to a knob by an operator cannot cause the side surface or front-back stress of a frame such that the side turning or front-back movement ofthe baby carriage in the unlocking process can be avoided.
本发明属于童车配件技术领域,具体而言,本发明涉及一种可旋转和锁定的活动关节,包括第一连接件和第二连接件,还包括活动限位装置,所述活动限位装置连接在所述第一连接件和所述第二连接件之间,所述活动限位装置在旋转时发生轴向位移以实现所述第二连接件的旋转和锁定。本发明的可旋转和锁定的活动关节有两种状态。使用时为支撑状态,收纳时为收纳状态。在应用于婴儿车时,可以通过旋转活动限位装置来实现解锁,便于婴儿车的收纳,在解锁时不需要按动按钮,利于使用者发力,能够降低操作难度;并且,操作者对旋钮施加的扭力不会造成车架侧面或前后受力,从而能够避免解锁过程中婴儿车的侧翻或前后移动。
