A stroller includes a frame, a first locking mechanism, a folding mechanism and a second locking mechanism. The frame is configured to be folded and unfolded between a folded state and an unfolded state. The first locking mechanism is disposed on the frame and for locking the unfolded frame and restraining the frame from being folded when the frame is in the unfolded state. The folding mechanism is movably disposed on the frame and connected to the first locking mechanism for driving the first locking mechanism to allow the frame to be folded. The second locking mechanism is disposed on the folding mechanism and separably abuts against the frame for restraining the folding mechanism from driving the first locking mechanism so as to lock the unfolded frame.

A twice-foldable stroller including a frame main body which is configured to have right and left front-angle frames to support front wheels and a horizontal frame connected at a lower part between the right and left front-angle frames, right and left rear-angle frames to support rear wheels and connecting frames connected between the right and left rear-angle frames and the right and left front-angle frames, and vertical frames connected to the right and left connecting frames; seat frames; backrest frames; support frames; extension frames; canopy frames rotatably connected to the extension frames; and handles, each connected to the extension frames, wherein right and left central portions are rotatably connected to each other.

A folding cart is disclosed, comprising: a frame comprising a front frame and a rear frame which are disposed face to face; a floor assembly, comprising a front frame member and a rear frame member which are hinged to each other and hinged between the front frame and the rear frame; a wheel retracting assembly comprising a rear wheel half-shaft rotary rod, a rear wheel half shaft, a rotary pulling rod, an automatic foot assembly and a rotary connecting bar; an end of the rear wheel half-shaft rotary rod is pivotally connected to the rear frame member, the rear wheel half shaft is disposed at the other end of the rear wheel half-shaft rotary rod for connecting a rear wheel; an end of the rotary pulling rod is pivotally connected to the rear frame member, and the other end is pivotally connected to the rear wheel half-shaft rotary rod to drive the rear wheel half-shaft rotary rod to retract.

The present disclosure relates to a twice-foldable stroller including: a frame main body 100 which is configured to have right and left front-angle frames 101 to support front wheels 101a and a horizontal frame 101 connected at a lower part between the right and left front-angle frames 101, right and left rear-angle frames to support rear wheels 102a and connecting frames 102 connected between the right and left rear-angle frames 102 and the right and left front-angle frames 101, and vertical frames 103 connected to the right and left connecting frames 102; seat frames 200; backrest frames 300; support frames 400; extension frames 500; canopy frames 600 and 600 rotatably connected to the extension frames 500 for sunshade; and handles 700 and 700, each connected to the extension frames 500 wherein right and left central portions are rotatably connected to each other, wherein each of the front wheels 101a and the front-angle frames 101 are rotatable via rotational axes R1 and R2, the front-angle frames 101 and the extension frames 500 are rotatable via rotational axes R3 and R4, and the handles 700 and 700 are rotatable via a rotational axis R5, which is a useful invention which is advantageous in that it significantly reduces the volume of a stroller by folding it twice, in which the stroller is folded again vertically when being in a horizontally folded state, and since it has a simple structure, it is possible to easily manufacture at a low cost as well as convenient to use, and can be used stably long term without breaking, which is economical and long lasting.
