Description

Wheel means of folding handcart for carrying gas tanks

The utility model relates to a kind of collapsible gaholder delivery dolly, particularly a kind of wheel assembly of climbing the building dolly.

Before the utility model is made, climb the building dolly and adopt several steamboats to overturn around center shaft to realize stair activity, because wheel is many, it is also many to rotate the position, and axle is excessive with the wearing and tearing of cover, and complex structure, and it is also excessive to deliver the gaholder physical demands of going upstairs.

The purpose of this utility model is: provide a kind of simple in structure, transmission performance well can be fit to long wheel assembly apart from push-and-pull again by light stair activity.

The utility model is achieved in that bull wheel, steamboat, shoulders the wheel carrier both sides that bar is installed in collapsible gaholder delivery dolly respectively, bull wheel and wheel shaft link joint by screw retention on wheel carrier, wheel carrier is provided with truck dead lever, by shouldering bar front end axis hole, fixing little wheel shaft, link joint steamboat make steamboat up the steps in the time of upstairs, under the effect of power, lift bull wheel by shouldering bar, overcome the step resistance.

Following the utility model provides embodiment to closing accompanying drawing.

Fig. 1. be the utility model steamboat running condition figure up the steps.

Fig. 2. for the utility model bull wheel lifts rotary state figure.

With reference to Fig. 1. wheel assembly is made up of with vehicle frame 4 bull wheel 1 steamboat 2 levers 3, turnover wheel carrier by collapsible gaholder delivery dolly, be separately fixed at the vehicle frame both sides, bull wheel is by the steel ball transmission, connect by screw by the wheel carrier spindle hole by bearing pin, steamboat is installed in the bull wheel front end by shouldering bar by screw.

With reference to Fig. 2. the bull wheel working state figure

The utility model volume is small and exquisite, and is simple in structure, in light weight, and the power that carries is strong, and wear resisting property is good, and it is supporting to be fit to the various building dollies of climbing, and is desirable cart for travelling up or down stairs wheel apparatus.
