Adopting the structure that the bottom facet is provided with four rows of rollers which slightly staggered for a distance of more than a roller radius, when people go up stairs, a former roller reaches the edge of the upper step. Although the latter roller of the same row is still on a lower step, the other row of rollers which are staggered for a distance of more than a roller radius are already on the vertical plane which is used to connected with the two level steps; therefore, when the case filled with heavy objects is pulled, the case walks on the steps.

The purpose of this utility model just be to provide a kind of can overcome can carry the Going upstair box of going downstairs on some heavier article.

For achieving the above object, the utility model is provided with handle at the casing front end, the bottom face of casing is provided with four row's rollers, be positioned at two row's roller solid matter and balanced configurations of the casing left and right sides, be positioned at also solid matter and the balanced configurations of the row's roller of two in the middle of the casing, be slightly more than the distance of a roller radius but stagger with the roller of the casing left and right sides.

After adopting said structure, because being provided with to stagger mutually at the bottom face of casing, the utility model is slightly more than four row's rollers of a roller radius, when going upstairs, when previous roller is taken the edge of upper level step, though same row's a back roller is also at the next stage step, but be positioned on the vertical plane that is connected the two-stage step with another row's roller of its about roller radius that staggers, like this, when dragging the Going upstair box that article are housed, just can make Going upstair box go on step, very easy to use.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is user mode figure of the present utility model

Accompanying drawing 2 is the side view of roller portion

Accompanying drawing 3 is the configuration schematic diagram of the utility model roller

The specific embodiment:

The following stated only is a kind of specific embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See shown in the accompanying drawing 1～3, Going upstair box main body 10 front ends described in the utility model are provided with the handle 20 that is used to tow Going upstair box, the bottom face of building box main body 10 of being expert at is provided with four row's rollers 30, be positioned at two row's roller 31 and 32 balanced configurations of Going upstair box main body 10 left and right sides, with row each roller array tight, certain clearance is arranged each other, be positioned at two also solid matter and balanced configurations of row's roller 33 and 34 of Going upstair box main body 10 centres, but staggering with roller 31 and 32 is slightly more than the distance of a roller radius, conveniently to pass the coupling spindle of roller 31 and 32; Certainly, roller 33 both can be the same with the number of roller 31 and 32 with 34 number, the number that can be less than roller 31 and 32, because Going upstair box 10 its front end in the process of towing always slightly lifts, the suffered power of the roller of its front end is less, therefore, when needs reduce the number of roller 33 and 34, several rollers of this two row's roller 33 and 34 front ends can be removed,, reduce cost to alleviate quality.

When on stair, towing the Going upstair box that article (baggages 40 as shown in accompanying drawing 2) are housed, when the previous roller in left and right two row's rollers 31 of Going upstair box and 32 ranks is taken the edge of upper level step, though same row's a back roller is also at the next stage step, but be positioned on the vertical plane that is connected the two-stage step with another row's roller of its about roller radius that staggers, like this, when dragging Going upstair box, just can make Going upstair box go on step like a dream, very easy to use.

When the utility model loaded with articles was gone downstairs, then because the asynchronous of rollers 31,32 arranged in the middle two row's rollers 33,34 and the outside two, the utility model was unlikely to sharply to roll downwards, makes the user be difficult to control, thereby like a cork article is transported downstairs.

Certainly, Going upstair box described in the utility model also can adopt power set other machinery or electric power to drag except dragging with manpower.In addition, the utility model can be walked as the mode of going upstairs in level road, also can walking sideling as usual suitcase.
