Description

Upper and lower stair waggon

Technical field

The utility model relates to a kind of daily go-cart, specifically, relates to a kind of upper and lower stair waggon.

Background technology

Have one day, seen such program in the Chinese Central Television (CCTV), the family of happiness has experienced unfortunate strike originally, and the hero is because of traffic accident, and the arm that broken is in and can't be gone to work, and can only do the thing of some within the reachs.All heavy physical labours all need to rely on wife to finish in the family, and the both shoulders of wife's softness are born the heavy burden of family.They stay in the lower building that does not have elevator, in daily life, often need the upper and lower stair of carrying thing, and the husband is seeing that weak wife bears white elephant like this, and is very bad at heart.

Now skyscraper is more and more, in daily production and life, often will carry the upper and lower stair of some weights, for example: live in the resident of the lower building that does not have elevator, carry some weights such as gaholder to upstairs; Have the storehouse of step on the goods yard workman often will transport goods, the place of the many steps in tourist attractions, famous mountain etc. generally all are to shoulder by manpower to lift weight, and this not only requires great effort time-consuming, but also danger close.At present, the dolly that also has some to go upstairs on the market, but can not load the heavier weight of component mostly, arbitrarily stair activity is not more accomplished to go up arbitrarily walking easily pacifically at stair.

The utility model content

The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of upper and lower stair waggon is provided, its simple and ingenious structure, easy to use, can random upper and lower stair, and can go up arbitrarily walking easily pacifically, and can load the heavier weight of component at stair.

For addressing the above problem, the utility model adopts following technical scheme:

A kind of upper and lower stair waggon of the utility model, comprise car body and handlebar, described car body is provided with bicycle basket, the car body two bottom sides is respectively arranged with a wheel mount pad, be respectively arranged with a spindle mounting hole on each wheel mount pad, by two spindle mounting holes a Wheel shaft be installed, the Wheel shaft two ends are respectively arranged with a cross bar, each cross bar is symmetrically arranged with 4 supports, an all hinged trundle on each support.During upper and lower stair, by handlebar pulling waggon, drive cross bar by main shaft and rotate, the trundle one after the other ground on the cross bar contacts with upper and lower stairway step face, realizes upper and lower freely stair.

For easy to use, increase the stability of waggon, the hinged strut bar in handlebar described in the utility model lower end, the hinged support wheel of described strut bar low side.Described strut bar has a main support rod and a side strut bar to constitute, described main support rod top is hinged on handlebar top, the hinged support wheel in described main support rod bottom, described side strut bar bottom is hinged on the bottom of main support rod, the side supporting bar top is hinged on the lower end of handlebar, on the handlebar, side strut bar hinged place is provided with upwardly extending side strut bar sliding tray.During the upper and lower stair of waggon, strut bar can shrink flexibly and comfortably,

For convenience of the load-carrying large piece article, bicycle basket described in the utility model is made of three frameworks, and described three frameworks are movable frame, and the bottom and the car body of three frameworks are hinged, and three framework places of interconnecting are for flexibly connecting.When loading large piece article, three frameworks are opened, and tiling, can increase the load-carrying area of car body easily as the bracing frame of large piece article.

The utility model is simple in structure, light and handy flexibly, easy for installation, with low cost, solved the difficult problem that present common hand barrow can not stair activity.

The utility model can not only travel on the level land, and can also be when upper and lower stair also can be with a wet finger, easily smooth-ride, alleviated people carry object when upper and lower stair labour intensity, have market popularization value widely.

The utility model is suitable for family, shop, office, school, hospital or other enterprise and institution, is used for short range carrying article, to alleviate the intensity of housework and occupational labor.

The specific embodiment

As shown in Figure 1, a kind of upper and lower stair waggon of the utility model, comprise car body 1 and handlebar 2, described car body is provided with bicycle basket 3, and the car body two bottom sides is respectively arranged with a wheel mount pad 4, is respectively arranged with a spindle mounting hole on each wheel mount pad, by two spindle mounting holes a Wheel shaft 5 is installed, the Wheel shaft two ends are respectively arranged with a cross bar 6, and each cross bar is symmetrically arranged with 4 supports, an all hinged trundle 7 on each support.During upper and lower stair, by handlebar pulling waggon, drive cross bar by main shaft and rotate, the trundle one after the other ground on the cross bar contacts with upper and lower stairway step face, realizes upper and lower freely stair.

For easy to use, increase the stability of waggon, the hinged strut bar 8 in handlebar described in the utility model lower end, the hinged support wheel 9 of described strut bar low side.Described strut bar has a main support rod 81 and a side strut bar 82 to constitute, described main support rod top is hinged on handlebar top, the hinged support wheel in described main support rod bottom, described side strut bar bottom is hinged on the bottom of main support rod, the side supporting bar top is hinged on the lower end of handlebar, on the handlebar, side strut bar hinged place is provided with upwardly extending side strut bar sliding tray 10.During the upper and lower stair of waggon, strut bar can shrink flexibly and comfortably,

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification sheets has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in the claim scope of the present utility model.
