Abstract

The invention discloses a four-wheel draw-bar box. The four-wheel draw-bar box comprises a draw-bar box body, and is characterized in that the two sides of the draw-bar box body are provided with hollow cavities, and shaft blocks are fixedly connected with the inner walls of the hollow cavities; each shaft block comprises a sheet steel part and a shaft part, and the shaft parts are in flexible connection with wheel-type elastic supporting legs; the outer sides of the wheel-type elastic supporting legs are provided with spacing sleeves fixed on the shaft parts, and the end surfaces of the shaft parts are provided with elastic levers. The four-wheel draw-bar box provided by the invention has the advantages that the structure is simple, the drag is easy, the shock can be absorbed, and people are unlikely to feel tired.

Description

technical field [0001] The invention relates to a four-wheel trolley case. technical background [0002] Most of the trolley cases on the market today are of two-wheel structure, and the four-wheel trolley case is only to solve the problem that the trolley case cannot be placed vertically. The resistance generated by the trolley case also needs to bear part of the gravity of the trolley case, so when there is a lot of luggage, dragging the trolley case will make the hands more tired, and if the ground is uneven, frequent vibrations when dragging the trolley case , exacerbated the degree of fatigue. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a four-wheel trolley case that is easy to drag, absorbs vibrations, and is not easy to be tired. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A four-wheeled trolley...
