Description

Multifunctional portable sliding baby draw-bar box

Technical Field

The utility model relates to the technical field of draw-bar boxes, in particular to a portable walking baby draw-bar box.

Background

The suitcase or the draw-bar box is always indispensable to tourists, and besides the suitcase is needed in the travelling process, the suitcase is also needed for common long-and-short-distance business operations;

At present, the existing suitcase has a single structure, is mostly provided with a zipper externally arranged on the suitcase body structure, and is generally provided with a pull rod;

With the improvement of the economic level in China, more parents choose to take children to travel together when traveling. When a child is small, for example, within 3 years old, most parents choose to hold the child in one hand and pull the suitcase in the other hand. Parents are very tired under this condition, and as the fatigue level of parents increases, the risk of the child falling increases. In order to alleviate fatigue, some parents choose to purchase a baby-holding waistband to hold the child in front of the chest. However, holding the child in front of the chest saves labor compared with holding the child, and parents can be tired for a long time, especially when traveling for a long distance;

Parents who push a child directly on a draw-bar box are also involved, but the suitcase is unstable when being pushed vertically or pulled, particularly the gravity center of the child is increased when sitting on the suitcase, and the risk of the child falling off and getting cold is high;

At present, in order to meet the above requirements, some draw-bar boxes with seats exist, but the child seat is simply fixed on the draw-bar boxes, so that two problems exist in the design, namely, when a child does not sit on the draw-bar boxes, the child seat occupies a large space and is inconvenient to drag, and parents also care for the child, and accompanying articles should be simplified as much as possible. Secondly, the draw-bar box can only be used when a child is taken out, and the draw-bar box cannot be used when the parent singly goes out at ordinary times, and the draw-bar box is also required to be additionally provided, so that the draw-bar box is not beneficial to saving resources.
