The invention discloses a frame locking mechanism and a trolley with the frame locking mechanism. The frame locking mechanism is used for unfolding or folding a frame. The frame comprises a handlebar, a front wheel bracket and a rear wheel bracket, and the front wheel bracket and the rear wheel bracket are both pivoted with the handlebar; the frame locking mechanism comprises a supporting assembly which is supported between the front wheel support and the rear wheel support, the supporting assembly comprises a first supporting piece and a second supporting piece which are pivoted with each other, the first supporting piece is pivoted with the front wheel support, and the second supporting piece is pivoted with the rear wheel support; and the locking device can lock or unlock the supporting assembly, so that the first supporting piece and the second supporting piece cannot pivot or can pivot relative to each other. Through the arrangement of the frame locking mechanism, the locking device can be driven to be unlocked through one action of a single hand, the supporting assembly is driven to be folded inwards, accordingly, the front wheel support and the rear wheel support are folded, folding of the trolley is achieved, the structure is simple, and operation is convenient.
本发明公开了一种车架锁定机构及具有该车架锁定机构的手推车,该车架锁定机构用于使车架展开或折叠;车架包括车手、前轮支架和后轮支架,前轮支架和后轮支架均与车手枢接;车架锁定机构包括:支撑组件,支撑在前轮支架与后轮支架之间,支撑组件包括彼此枢接的第一支撑件和第二支撑件,第一支撑件与前轮支架枢接,第二支撑件与后轮支架枢接;锁定装置,能够锁定或解锁支撑组件,使得第一支撑件和第二支撑件相对于彼此不能枢转或能够枢转。本公开通过车架锁定机构的设置,单手一个动作就可驱动锁定装置解锁,带动支撑组件向内收拢,从而使前轮支架和后轮支架折叠,来实现手推车的收合,结构简单、操作方便。
