Abstract
The utility model relates to a hand-pull four-wheel upstairs cart, which comprises a cart frame and a cart shaft under the cart frame. The hand-pull four-wheel upstairs cart is characterized in that both ends of the cart shaft are provided with four-wheel assembled wheels, and the four-wheel assembled wheels are provided with star-shaped four-direction wheel frames which are provided with wheel frame shafts. The wheel frame shafts are provided with four wheel supporting rods in four directions and every two supporting rods are parallel to each other. Contiguous wheel supporting rods are perpendicular to each other. The inner sections of the four wheel supporting rods form a square, and the four wheel supporting rods are in the same one plane. The wheel supporting rods are provided with shaft holes; the distance between two contiguous axle holes of the wheel supporting rods is larger than or equal to the height of the step of a stair. The outer ends of the four wheel supporting rods are respectively provided with a castor. The utility model is provided with four-wheel assembled wheels, and the four-wheel assembled wheels are provided with the wheel frame; the wheel frame is provided with four castors in four directions, and the distance between two contiguous wheel axles is greater than or equal to the height of a stair; the wheel frame of the four-wheel assembled wheels can rotate around the axle of the wheel frame. Therefore, the hand-pull four-wheel upstairs cart can be pulled along stairs to climb upstairs.
Description
Technical field
The utility model relates to a kind of manpower push-and-pull vehicle, particularly a kind of wheel of manpower push-and-pull vehicle.
Background technology
The manpower push-and-pull vehicle has vehicle frame, under the vehicle frame axletree is arranged, and there is wheel at the two ends of axletree.In the prior art, the axletree two ends under the manpower push-and-pull vehicle vehicle frame have only a wheel respectively.This manpower push-and-pull vehicle only is suitable for walking on the level land, can not walk up and down along the step of stair.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of can walk up and down along the step of stair pull the four-wheel cart for travelling up or down stairs.
The utility model is realized with the following method.
Pulling the four-wheel cart for travelling up or down stairs has vehicle frame, under the vehicle frame axletree is arranged, and there is the four-wheel built-up wheel at the two ends of axletree, and the four-wheel built-up wheel has
The four directions of font is to vehicle wheel frame,
There is the vehicle wheel frame axle in the four directions of font to vehicle wheel frame, four parallel in twos wheel strut bars of four direction are arranged on the vehicle wheel frame axle, adjacent wheel strut bar is orthogonal, section is formed square in four wheel strut bars, four wheel strut bars at grade, there is axis hole wheel strut bar outer end, and distance is equal to or slightly greater than the height of stairway step between the axis hole of adjacent wheel strut bar, and the outer end of four wheel strut bars has castor respectively.
During use, the utility model can be walked on the level land, and the people who pulls a cart can or pull the handlebar of vehicle frame with hand push, and two castors of the vehicle wheel frame top and bottom of the four-wheel built-up wheel at axletree two ends drop on and rotate walking on the ground, and two castors are in the above in addition.In the time of upstairs, before the step of stair, the people who pulls a cart goes before, the handlebar that pulls vehicle frame along the step of stair to up, after dropping on ground castor and being blocked by stairway step,
The four directions of font can be rotated around the vehicle wheel frame axle to vehicle wheel frame, and a superincumbent castor can drop on the upper class step, along with
Rotate to vehicle wheel frame in the four directions of font, being blocked caster wheel by step below can rise on the above-mentioned upper class step along the vertical surface rolling of this step, finish the process that steps to a new level, being raised on the upper class step caster wheel can blocking by the stairway step of higher level, repeat above-mentioned process upstairs then, it is up along the step of stair to haul the utility model one-level one-level ground; In the time of downstairs, pushing away the utility model, below caster wheel roll along the vertical surface of step and drop on the next stage step,
Rotate around the vehicle wheel frame axle to vehicle wheel frame in the four directions of font, above caster wheel fall on the above-mentioned next stage step, finish the process of next step, along with
Rotate to vehicle wheel frame in the four directions of font, repeats above-mentioned process downstairs, and it is descending along the step of stair to push away the utility model one-level one-level ground.
The utility model has the four-wheel built-up wheel, the four-wheel built-up wheel has vehicle wheel frame, four castors that four direction is arranged on the vehicle wheel frame, the interaxle distance of adjacent castor is more than or equal to the height of stairway step, the vehicle wheel frame of four-wheel built-up wheel can rotate around the vehicle wheel frame axle, so the utility model can be pulled to reposefully upstairs or be pulled to downstairs along stairway step.
Below in conjunction with accompanying drawing, the utility model is further described.
