Abstract

The utility model relates to a van, which comprises a van frame, wheels and a main shaft, wherein the main shaft is welded on the middle of the bottom of the van frame, and the wheels are respectively connected on the two ends of the main shaft. The wheel is formed by a wheel body, a bearing, a rubber wheel and a connecting shaft, wherein the bearing is embedded on the center of the wheel, and the bearing is sleeved on one end of the main shaft to connect the wheel and the van frame, four wheel arms which are mutually perpendicular are arranged on the wheel body, a concave port is arranged on the top end of the wheel arm, through-holes are arranged on the two sides of the concave port, a shaft hole is arranged on the center of the rubber wheel, and the connecting shaft is passed through the through-hole on the top portion of the wheel arm and the shaft hole of the rubber wheel to connect the rubber wheel shaft on the center of the concave port. The van has the beneficial effects that the function of transporting objects on the flat ground can be realized through the stress on the two wheel arms and the rolling of the rubber wheel, and the function of transporting goods on up-and-down stairs can be realized through the alternative stress on the four wheel arms.

Description

A kind of transport trolley

Technical field

The utility model relates to a kind of transport trolley.

Background technology

At present, transport trolley on the market is circular wheel mostly, this type of transport trolley, easy to use when on the level land, transporting goods, simple, but use difficulty in the place that step or stair are arranged, not only do not have effect easily, also can increase burden, this just makes the use zone of transport trolley be subjected to very big restriction.

The utility model content

The purpose of this utility model provides a kind of transport trolley, to overcome the above transport trolley function way mono-deficiency.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of transport trolley, comprise vehicle frame, wheel, main shaft, be welded with main shaft in the middle of the bottom of frame, the main shaft two ends respectively are connected with wheel, described wheel is made up of wheel body, bearing, rubber wheel and adapter shaft, wheel center interlocking bearing, bearing inner ring is socketed in main shaft one end wheel is connected to ground together, described wheel body is provided with four orthogonal arms of taking turns, there is recess on the top, the recess both sides are provided with through hole, and described rubber wheel centre has axis hole, adapter shaft to pass the through hole at wheel arm top and the axis hole of rubber wheel is coupling rubber wheel in the middle of recess.

The beneficial effect of transport trolley described in the utility model is: stressed by two wheel arms, rubber wheel rolls, and can realize the function of level land carrying article; By four the wheel arms alternately stressed, can be implemented in the function that stair activity transports goods.
