A support anti-breaking structure includes a first plate member (1), a second plate member (2) and a first fixing member (3). An end of the first plate member (1) is pivotally connected to an end of the second plate member (2) at a first pivotal connection (51). The first fixing member (3) is formed by a flexible structure and fixed to a side of the first pivotal connection (51). The first plate member (1) and the second plate member (2) can press the first fixing member (3), so that the first plate member (1) and the second plate member (2) can be rotatably folded. When the first plate member (1) rotates relative to the second plate member (2) in a direction of pulling the first fixing member (3), the first fixing member (3) will exert reaction force to the first plate member (1) and the second plate member (2) by structural strength itself, thereby restraining the rotation of the first plate member (1) relative to the second plate member (2), so as to effectively reduce the probability of breaking the first pivotal connection (51) due to incorrect operation of the rotation and folding.

Disclosed are a child seat frame and a compact foldable stroller. The child seat frame comprises a seat mounting part, a lower frame body, and an upper frame body, wherein the upper frame body is provided with an upper frame body lock which can be actuated to lock and disengage from a second latch part, and the upper frame body is pivotable relative to a lower seat frame hub when the upper frame body lock is disengaged from the lower seat frame hub; and when the lower frame body pivots relative to the seat mounting part, the upper frame body lock locks over the second latch part. The child seat frame can be folded in a main suitable for the folding boundary dimensions of a main stroller frame, thereby maintaining the folding dimensions of a stroller unit to a minimum.

A foldable baby stroller that can comprise collapsible telescoping support shafts connected by a hinged handle. Pivot assemblies support the support shafts and two pairs of legs including at least one pair of rotating legs and one pair of fixed legs, each leg including an attached wheel. The pair of rotating legs when in a closed configuration fit below, adjacent, and parallel to the fixed pair of legs with the attached respective wheels of each pair arranged in tandem. A hinged support brace links the pair of pivot assemblies and locks in an extended configuration. Two seat supports attaching a seat to the stroller and fold upward 90° to facilitate configuring between the extended configuration and folded configuration by folding upward. The pivot assemblies facilitate folding the support shafts when in the retracted configuration, and the two pairs of legs when in the retracted configuration, together into the folded configuration.

The utility model provides a baby trailer with convenient storage, which comprises a trailer frame and a storage structure. The trailer frame comprises a front side frame, a rear side frame, a rear chassis frame. The front chassis frame is hinged with the front side frame. The rear chassis frame is hinged with the rear side frame. The storage structure is hinged with the front side frame and the rear side frame, so that the front frame and the rear side frame are capable of folded. The storage structure comprises two storage frames, a connecting rod. The connecting rod is connected with the left storage frame ,the connecting rod is connected with the right storage frame. The ends of the front chassis frame and the rear chassis frame are movably placed on the connecting rod. The baby trailer has the advantages of convenient storage and small occupied space after storage.

The invention relates to a foldable device (3000) for transporting loads, the foldable device comprising: a first platform (3200); a running gear (3100), the running gear comprising a plurality of arms (3110) and a plurality of wheels (3130), each of the plurality of arms being rotatably coupled to the first platform and at least one of the plurality of wheels; and a device for aligning the plurality of arms and the plurality of wheels, which is configured to rotate each of the plurality of arms and each of the plurality of wheels by a rotary angle between at least one open and one folded state, wherein the plurality of arms and the plurality of wheels are arranged under the first platform when in the folded state.

A seat includes a seat plate, a first backrest support member, a second backrest support member, a third backrest support member, a first sliding sleeve and a second sliding sleeve. The second backrest support member is telescopically connected to the first backrest support member. The third backrest support member is telescopically connected to the second backrest support member and pivotally connected to the seat plate. The first sliding sleeve is disposed on the first backrest support member. The second sliding sleeve is disposed on the second backrest support member. The first backrest support member, the second backrest support member and the third backrest support member are able to slide with respect to each other to be folded or unfolded. The first sliding sleeve slides as the first backrest support member slides, and the second sliding sleeve slides as the second backrest support member slides.

A stroller includes a frame, a sliding member and a seat fixing base. The frame includes a front linkage rod and a transverse rod. The transverse rod is disposed with respect to the front linkage rod. The sliding member is rotatably connected between the transverse rod and the front linkage rod. The seat fixing base is rotatably connected to the transverse rod or the front linkage rod and slidably connected to the sliding member. When the frame is folded, the front linkage rod and the transverse rod move away from each other, such that the seat fixing base slides with respect to the sliding member.
