Abstract
The utility model discloses a multifunctional creeping cart, comprises a cart body (1) and wheel axles (4) which are arranged on the cart body (1). The wheel axles (4) on both sides of the cart body (1) are respectively provided with a rotary star-shaped wheel carrier (2), and a wheel arm of the wheel carrier (2) is provided with a rolling wheel (5). The wheel axles (4) on both sides of the cart body (1) are also respectively provided with a transition wheel (3) which is arranged side by side with the wheel carriers (2). By adopting the structure, when the multifunctional creeping cart is used on flat ground, four wheels land and roll to advance, so the cart body (1) is easy to be balanced; When the multifunctional creeping cart creeping stairs with load, the position of the step corner is provided with the transition wheel (3), so the wheel carrier (2) can not encounter the step corner to jolt or damage the stairs. The multifunctional creeping cart has the advantage of simple in structure, small in volume, light in weight, labor saving and stable for creeping stairs.
Description
Technical field
The utility model relates to a kind of hand buggy, particularly a kind of can the use on level road, the multi-functional cart for travelling up or down stairs of again can load-carrying climbing the building.
Background technology
Present hand buggy comprises car body, wheel shaft and is arranged on roller on the wheel shaft of car body both sides, because volume is little, light flexibly, uses during suitable especially journey; But weak point is also arranged, the one, when load-carrying was used on level road, the car body balance was difficult for grasping; The 2nd, when the building was climbed in load-carrying, every previous step step all will have and equiponderant hoisting force, and therefore, it is quite painstaking to climb the building with hand buggy.For this reason, many people have proposed many different solutions at above problem, as China Patent No. is 012529435 to disclose a kind of " laborsaving cart for travelling up or down stairs ", though this car has solved the problem of climbing the building basically, but this car vehicle wheel frame when climbing the building can be run into the corner of step, not only stair can be damaged, and the vibration of jolting can be produced.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing hand buggy and cart for travelling up or down stairs exist, the utility model provide the easy balance of a kind of car body, upstairs laborsaving, vibration is little, climb the multi-functional cart for travelling up or down stairs of building pulsation-free.The technical scheme that its technical matters that solves the utility model adopts comprises car body and the wheel shaft that is arranged on the car body, is respectively equipped with rotary star vehicle wheel frame on the wheel shaft of described car body both sides, and the wheel arm of star vehicle wheel frame is provided with roller.
Roll when preventing that vehicle wheel frame from running into the step corner and being convenient to corner for upstairs the time, be respectively equipped with on the wheel shaft of described car body both sides and star vehicle wheel frame transition wheel side by side.
For reduced volume, described transition wheel is preferably disposed on the inboard of star vehicle wheel frame, can certainly be arranged on the outside.
For the ease of the transition of step corner, the diameter of described transition wheel is more preferably greater than the diameter of roller.
After adopting said structure, when using on level road, four-wheel lands to roll and advances, and the car body balance is easy, when the building is climbed in load-carrying, in the step corner transition wheel transition is arranged, and vehicle wheel frame can not run into the corner of step, just can not damage the stair and the vibration of jolting yet; Have simple in structure, volume is little, in light weight, upstairs laborsaving, climb advantages such as the building is steady.
