An expandable cart includes a lifting mechanism, and a first folding mechanism, a second folding mechanism, a third folding mechanism, and a fourth folding mechanism capable of being folded and contracted. The lifting mechanism includes a first telescopic column, a second telescopic column, a third telescopic column, and a fourth telescopic column arranged vertically and capable of telescoping. The first telescopic column, the second telescopic column, the third telescopic column, and the fourth telescopic column are rectangularly arranged at intervals, and the first folding mechanism, the second folding mechanism, the third folding mechanism, and the fourth folding mechanism are sequentially connected between two adjacent telescopic columns. The four telescopic columns are contracted to a shortest state and close to each other, thereby effectively reducing the folding volume of the expandable cart, and facilitating storage and carrying by a user.

A folding cart includes a first frame assembly, a second frame assembly, a first folding assembly, and a second folding assembly. The first folding assembly and the second folding assembly are opposite to each other, a first end of the first folding assembly and a first end of the second folding assembly are connected to the first frame assembly, and a second end of the first folding assembly and a second end of the second folding assembly are both connected to the second frame assembly. The first folding assembly and the second folding assembly can be switched between a first state and a second state.

A cart with sliders having a hand lever, a front frame, a back frame, two symmetrical side frames and a chassis, wherein the hand lever is rotatably connected with the front frame, the front frame and the back frame are identical in structure, each of the side frames having two X-shaped cross tubes and two sliders, the chassis having a bottom tube and two bottom frames, one ends of the two bottom frames are articulated, the other ends of the two bottom frames are riveted to the front frame and the back frame respectively, the bottom tube is arranged below the bottom frames, and two ends of the bottom tube are riveted to an upper articulated joint of the two X-shaped cross tubes of one side frame and an upper articulated joint of the two X-shaped cross tubes of the other side frame respectively.

The double-sliding sleeve collapsible folding trailer comprises: a vertical rod assembly, left and right side folding assemblies, a front and rear side folding assembly, a bottom supporting assembly and a wheel assembly; four vertical rods are provided in a rectangular distribution and fixed with upper retaining brackets and lower retaining brackets at both ends, and with linkage sliding sleeves for vertical free sliding; the left and right side folding assemblies, the front and rear side folding assembly and the bottom supporting assembly are provided with a linkage sliding sleeve respectively. The cross sliding sleeves of each folding assembly with the linkage sliding sleeves on the vertical rods, realize the linkage structure design of multi-sliding sleeves to effectively optimize the folding structure, significantly improve the smooth folding and unfolding process, achieve a larger unfolding capacity and a more compact folded state for convenient storage with smaller volume and height.

A stroller is foldable from an erect position to a collapsed position and vice versa. The stroller comprises a collapsible folding mechanism provided with a push bar and at least one four-bar linkage mechanism. The push bar comprises a first part provided with a handle. The first part is pivotably connected to a first bar of the four-bar linkage mechanism. The push bar further comprises a second part pivotably connected to a second bar of the four-bar linkage mechanism. Ends of the first part and the second part are pivotably connected at a pivot to each other. The first part and the second part are detachably lockable with respect to each other in the erect position of the stroller to prevent collapsing of the four-bar linkage mechanism.

A cart includes a platform assembly, a handle assembly, first wheel assembly and a second wheel assembly. In use, the cart may folded from a deployed position in which it rolls along a surface to transport items, to a stowed position, in which it is collapsed in a compact geometry for storage. The cart may be further integrated into a chair, chaize lounge, garden cart, bicycle utility cart or a bicycle passenger cart.

A collapsible stroller includes a stroller frame, a folding lock mechanism, a lateral lock mechanism, and a trigger mechanism. The stroller frame includes a right upper side frame member pivotally connected with a right lower side frame member and a left upper side frame member pivotally connected with a left lower side frame member. The folding lock mechanism is capable of a locked state and an unlocked state. The lateral lock mechanism is capable of a locked operating state and an unlocked operating state. The trigger mechanism is on the stroller frame, and actuation of the trigger mechanism moves the folding lock mechanism from the locked state to the unlocked state and moves the lateral lock mechanism from the locked operating state to the unlocked operating state.

The present invention discloses a foldable stroller, comprising: a front wheel support frame, a rear wheel support frame, a seat support and push rods, the lower end of the front wheel support frame is provided with front wheel assemblies, and rear wheel assemblies are arranged at the lower end of the rear wheel support frame, the push rods each are connected to the front wheel support frame and the rear wheel support frame with pivot assemblies, the foldable stroller comprises not only a first folding structure that is connected with the pivot assemblies and capable of folding the push rods, but also a second folding structure capable of folding the front wheel support frame and the rear wheel support frame. The present invention has the advantages of simple structure, low cost, convenient assembly, smooth and easy folding, small folding size and convenient collection.

A multiuse foldable furniture including a main body and two sets of side supports, the main body includes a seat plate and a back plate, the seat plate is hinged with the back plate, the two sets of side supports are respectively disposed at two sides of the main body; each set of side support includes a front support, a back support, and a retracting sleeve, the retracting sleeve is slidably sleeved outside the front support, the retracting sleeve is hinged with the back plate, the top of the front support is hinged with the back plate, the top of the back support is hinged with the seat plate, a supporting connector is set between the front support and the back support, an inner side and an outer side of both ends of the supporting connector are hinged with the front support and the back support, respectively.

A foldable cart has a stabilizing handle device, which includes a connecting seat. The connecting seat has a connecting groove and two connecting rods of the foldable frame of the foldable cart are pivotally connected to the connecting seat in the connecting groove. A pulling rod mechanism is pivotally connected with the connecting seat. The connecting seat has a fixing strut that extends between the connecting seat and the foldable frame. When the cart frame is folded, the two connecting rods rotate about their pivot connections with the connecting seat, so that the two connecting rods approach each other. The connecting seat is fixedly connected to the fixing strut and a pivot point on the front side of the foldable frame so that an angle between the two remains fixed, which prevents the pulling rod mechanism from toppling left and right.
