Description

Technical Field

[0001] The utility model relates to the technical field of medical carts, in particular to a children's medical cart with a seat which is convenient for storage. Background Art

[0002] At present, most of the existing pediatric medical strollers on the market adopt a fixed seat design. Although this design is simple in structure, in actual application, the seat cannot be folded, resulting in a large space being occupied when not in use. Especially in medical institutions, where space resources are precious, the fixed seat design is not conducive to efficient use of space. Moreover, the fixed seat cannot be adjusted according to the different body shapes and treatment needs of children, which may affect the comfort and safety of children, especially in long-term use or special treatment situations.

[0003] Recent attempts at improvement include the introduction of a stroller with a detachable seat, such as a stroller with a seat having a publication number of CN216886856U, which has an unfolded state and a folded state, and includes a frame structure composed of a front frame, a rear frame, a bottom frame and two side frames, and an upper two-folding rod and a lower two-folding rod hinged to the front frame and the rear frame are respectively provided at both ends of the side frame, and a detachable seat is provided in the frame structure. The seat on the stroller includes a backrest and a seat cushion of an integrally formed design, and there is a gap between the seat cushion and the bottom frame. The seat in the stroller is connected to the frame structure by hanging. In the loading state, the stroller can carry children through the seat and leave a certain amount of space for loading items. After the seat is removed, the amount of items loaded in the stroller can also be increased. The patent document discloses a stroller with a seat. Although this design allows the seat to be removed to increase the space for loading items, the seat is an integrated structure and is fixed to the stroller by hanging on both sides. When carrying a certain weight, the stability and safety may be reduced, and the structural design cannot play a good fixing role for the child on the seat, and is not suitable for younger children to ride. In addition, the trolley with the publication number CN110356448A specifically discloses an expansion system of the trolley, including a frame composed of two side frames in folded and unfolded states, the expansion system includes an expansion seat and a support rod for installing an expansion device, the expansion system connects the expansion device to the frame through the expansion seat, and the expansion seat is also detachably connected to the frame. In a scenario where the expansion system is not needed, the expansion system will not affect the use of the trolley; when the expansion device is needed, the expansion system can also be quickly installed. The technical solution disclosed in the present application is neat and easy to carry after folding; it has a large space and a stable structure after unfolding; however, the structural design will make the child's riding position higher, so that the center of gravity of the entire trailer rises, which is not conducive to the overall stability of the trailer. In addition, in the above two solutions, when the trolley is in the stored state, the seat can only be taken out and stored separately, and the entire trolley is inconvenient to carry and store.

[0004] To overcome these limitations, a new design is needed to improve the practicality, safety and convenience of pediatric medical carts. Utility Model Content
