Abstract
The utility model discloses a portable zero-pressure traveling case which comprises a case body, a cushion layer, a rotating shaft, and a support body with universal wheels, and is characterized in that the universal wheels are arranged at the grounding end of the support body. When the traveling case is pulled, the traveling case is supported on the ground by three wheels in a balanced manner, so that the intensity of the stress against a draw bar can be extremely reduced; and a user can stably move the traveling case by only overcoming the rolling friction force of the ground against the traveling case.
Description
Technical field
The utility model relates to the bar traveling box technical field, relates in particular to the portable suitcase of zero pressure.
Background technology
Bar traveling box can be converted into a part of weight of luggage in the case pressure of wheel to ground, thereby alleviates the pressure of luggage to human body.But also there are two significantly deficiencies in bar traveling box: first pull bar is damaged by heavy back easily; Two to be old and weak people, women and childrens still can feel inconvenience to moving heavier luggage for it.Existing product and achievement in research often concentrate on Tiebar structure, folding facility and multi-functional angle.For example, " single tube bar traveling box (patent No. ZL201020576880.4) " is designed to general bar traveling box a kind of bar traveling box of single tube pull rod device; It is light that " Foldable lightweight bar traveling box (patent No. ZL201020656108.3) " is conceived to carrying of empty van; " seat formula bar traveling box (patent No. ZL200920119674.8) " proposed a kind of new scheme from the multipurpose angle.These researchs or product all do not solve the obvious deficiency that bar traveling box exists.
Summary of the invention
The utility model proposes the portable suitcase of a kind of zero pressure to the deficiency that bar traveling box exists.
The measure that the utility model is taked is: one of the outer middle and lower part installation of the rear box of general bar traveling box can 90 ° of rotations supporter; The end that contacts to earth of supporter is installed universal wheel; Three wheel balanced support ground are arranged when making the pulling suitcase; Make and casing, bed course, rotating shaft and have the supporter of universal wheel constitute the portable suitcase that the user is not had pressure.
The beneficial effect of the utility model is can farthest reduce the force intensity that receives of pull bar, as long as the user in the face of the force of rolling friction of suitcase, just can make suitcase steadily move with overcoming.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the cutaway view of the utility model.
Fig. 2 is the expanded view of the utility model.
Among the figure, 1. casing, 2. bed course, 3. rotating shaft, 4. supporter, 5. universal wheel.
The specific embodiment
