Abstract: This design is to modify the cargo space to make it layered and adjustable,to keep the current couriers away from turning the whole cargo space up and down with all the cargoes of different shapes and sizes piled up at the same cargo space.According to the size or weight of the package,it is reasonable to divide the cargo space into three spaces,the upper,the middle and the lower space.The bottom surface of upper space is adopted with guide rail structure and the bottom surface of the middle space is adopted with parallelogram structure,both of which can be moved in parallel translation.The middle space and the lower space can be also adjusted according to the size of the package with usage of the electric telescopic rod.It is able to make the express simpler and more efficient with easier placing and picking,enlarge the load capacity,ensure the good condition of the items during loading and unloading in the express.The structure design is simple and reasonable,and the material of the parts is very common with low cost and easy market popularization.
