Collapse-proof easy-to-stack draw-bar box for consignment

Abstract

The invention discloses a collapse-proof easy-to-stack draw-bar box for consignment, and relates to the technical field of draw-bar boxes. The draw-bar box comprises a first shell, the lower surface of the first shell is fixedly connected with the upper surface of a second shell through a closing device, and the back side of the second shell is hinged to the back side of the first shell through two hinges. Four protrusions are arranged on the lower surface of the second shell, and four fixing blocks at the positions corresponding to those of the four protrusions are arranged on the upper surface of the first shell, clamping grooves are formed in the upper surface of the four fixing blocks respectively, and sliding grooves are formed in the left and right side faces on the inner walls of the first and second shells respectively. According to the collapse-proof easy-to-stack draw-bar box for consignment, through the combined action of springs, sliding rods, sliding sleeves, carrying plates, connection blocks, elastic belts, sliding grooves and sliders, shock absorption of items is achieved, the probability that the items are damaged by impact is reduced, and therefore, the loss of people is reduced.
