Description
Affiliated technical field
The utility model relates to the hand-propelled vehicle technical field, particularly relates to a kind of building barrier-exceeding vehicle of climbing.
Background technology
At present, Urban House is a storied building structure mostly, and it is very inconvenient to carry Weight upstairs climbing, and existing baggage car is because the restriction of car wheel structure is not suitable for load-bearing upstairs.Though also occurring as the patent No. is the cart for travelling up or down stairs of ZL991242637, complex structures all, the cost of manufacture height is not easy to deposit, special when climbing the last single order of every section stair out of reach labour-saving effect, it is convenient inadequately to use.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of simple in structure, use labour-saving multifunctional barrier-crossing car is provided.
For achieving the above object, the utility model is by the following technical solutions: it comprises that front end has the vehicle frame of handgrip, in the both sides of vehicle frame a tri-star wheel is installed respectively, each tri-star wheel is by a center gear, three star-wheel poles that become hexagonal angle to be fixed on the center gear constitute with the star-wheel that is installed in star-wheel pole end, be fixed with the telescopic supporting rod sleeve pipe at the vehicle frame rear portion, in this sleeve pipe spring is housed, there is the telescopic supporting rod that is contained in the sleeve pipe outer end of spring, the inner of telescopic supporting rod is connected with backguy, and the end in addition of backguy is connected with the telescopic supporting rod bar handle that hinge is contained on the handgrip.
The utility model is simple in structure, and cost of manufacture is low, deposits conveniently, applies easily.Owing to be provided with telescopic supporting rod mechanism, both can load-bearing climb the building, use laborsavingly, also can steadily walk on the level land, can also be in the use of rough highway section, applied widely.
Description of drawings
Fig. 1 is a lateral plan of the present utility model;
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment
The accompanying drawing illustrated embodiment, the rear portion that front end has the vehicle frame 1 of handgrip 2 is fixed with wheel shaft 8, wheel shaft 8 two ends respectively are equipped with a tri-star wheel, each tri-star wheel by a center gear 3, become hexagonal angle to be fixed on three star-wheel poles 4 on the center gear 3 and the star-wheel 5 that is installed in star-wheel pole 4 ends constitutes.The telescopic supporting rod sleeve pipe 6 that is fixed on the vehicle frame 1 is arranged at wheel shaft 8 rear sides, in this sleeve pipe 6 spring 9 is housed, there is the telescopic supporting rod 7 that is contained in the sleeve pipe 6 outer end of spring 9, the inner of telescopic supporting rod 7 is connected with backguy 10, and its other end of aperture that backguy 10 is passed on the sleeve pipe 6 is connected with the telescopic supporting rod bar handle 11 that hinge is contained on the handgrip 2.
When hauling this car and climb the building, it is static that at first last star-wheel is run into stair, and because of center gear also is a driving wheel, back one star-wheel lifts under tension, the middle star-wheel higher level's step that crawls toward, and the like.When climb to every section stair go up single order most the time, because last star-wheel is accessible again to be stopped, back one star-wheel can not lift, eject telescopic supporting rod by the telescopic supporting rod bar handle this moment, press down handgrip, hold up back one star-wheel pole, can easily finish and climb the step task, and utilize the two-wheeled walking that lands.When stair climbing once more, utilize backguy to get final product in the telescopic supporting rod indentation sleeve pipe.
