Box body strengthening structure and draw-bar box

Technical Field

The invention relates to the field of luggage cases, in particular to a case body strengthening structure and a draw-bar case.

Background

The draw-bar box in the prior art is easy to deform under the action of external force, and particularly the box cover part is easy to indent and deform under the compression of the external force. In order to prevent the draw-bar box from being distorted excessively to cause troubles and inconvenience for practical use, at present, as shown in fig. 1, plastic and V-shaped or S-shaped rib and rib supporting structures are added on the basis of rib and rib structures of the box body in some market for reinforcing and supporting. However, this method requires a new and complicated mold design for the tank, and the plastic strength is relatively weak, and the requirement for plastic material is large, which increases the manufacturing cost of the tank.
