摘要： A side-opening child car chassis and a side-opening child car refer to a child car technical field. The side-opening child car chassis includes a main load-supporting chassis, car body connection assemblies, stabilizer brackets, a reinforcement member lock device, and an unlock device. The main load-supporting chassis includes a middle protective chassis and a rear chassis and a front chassis that are respectively and rotatably mounted at a front side and a rear side of the middle protective chassis. There are two groups of the stabilizer brackets, one group of the stabilizer brackets is mounted on the left of a bottom portion of the main load-supporting chassis, another group is mounted on the right of the bottom portion of the main load-supporting chassis, each group of stabilizer brackets in an expanded state has a V shape, and a tip faces inwards.

摘要： A gathering-type folding cart frame comprises a plurality of support mechanisms and corresponding wheels arranged under the support mechanisms, a central folding mechanism is arranged between the support mechanisms, enclosure folding mechanisms are arranged on the cart frame, and a handle is arranged on one side of the cart frame in the direction of travel; after the central folding mechanism is folded, the support mechanisms gather towards the central folding mechanism. The invention adopts a gathering-type folding method, and can be folded in the length direction and width direction at the same time after folding, the folding method is simple, easy to use, the folded volume is small, there is no sharp angle structure, and there is no safety hazard. The invention is provided with enclosures on the top of the cart frame, which can improve the strength of the top of the cart frame.

摘要： A delivery dolly includes a carousel that is rotatably mounted on a support column. The carousel includes a recess on an underside of the carousel. A locking mechanism is biased toward a locked position. The locking mechanism includes a locking wheel on which the carousel rotates until the carousel reaches a preselected angular position. The recess aligns with the locking wheel at the preselected angular position and, due to a bias force, the locking wheel extends into the recess to inhibit rotation of the carousel until the carousel is spun manually, forcing the carousel to rotate and the locking wheel to retract until the locking wheel encounters the recess again.

摘要： Provided is a foldable pull rod box, including two panels, bottoms of which are provided with roller wheels. One of the panels is provided with a retractable pull rod. Side plate assemblies are hinged between two ends of the two panels. The side plate assembly includes two side plates hinged with each other. The bottom of one of the panels is hinged with a bottom plate, and an inner wall of the side plates and/or the other panel is provided with a support portion. When the side plate assemblies unfold to a flat state and the bottom plate unfolds to a horizontal state, a containing cavity with an open upper end is formed between the side plate assemblies and the panels. One of the panels is provided with a buckle. The advantages of the disclosure are enjoying compact structure, convenient operation and good use effect, which is convenient to carry.
