Description

Multi-function foldable trolley for upstair

The utility model relates to a kind of multifunction folding and climbs the building dolly.

The utility model belongs to household implements and articles for use technical field.

Existing three-wheel is climbed the building device can only remove the object of row below 15 kilograms, and people of the object more than 15 kilograms is difficult to drag upstairs, and the also inconvenience of turning round of going upstairs, and therefore stays in high-rise building and walk-up resident still feels difficulty.

Building is more and more now, and the Urban House below eight layers is not installed elevator mostly, and people carry the Weight upstairs climbing inconvenience.To be that design is a kind of can load-carrying climb the building dolly below 50 kilograms to the purpose of this utility model, go upstairs and turn round flexibly, can carry Weight upstairs climbings such as cylinder for liquefied gas, honeycomb briquette, whilst on tour can be made baggage car, also can work as little stool uses, not collapsible collection of time spent, total weight are less than 4 kilograms, to solve the inconvenience of people's life.

The utility model is achieved in that multifunction folding climbs the building dolly, form by upper bracket, lower bracket, work-saving device, securing device, honeycomb briquette basket, cylinder for liquefied gas pad, cushion, stretching frame, support is by the aluminium-alloy pipe formation of φ 16 * 1.5, can reach lightweight purpose.Respectively there are three rubber tires by 120 ° of distributions on the dolly both sides, and in the time of upstairs, under the effect of pulling force, three rubber tires are rolling successively and contacting with stair, thereby a step is climbed up the building with connecing a step.Dolly is furnished with work-saving device, and work-saving device is made up of depression bar, shift fork, stage clip, driving lever, pull bar, torsion spring etc., and depression bar is pressed down, and depression bar drives driving lever, and driving lever is stirred glue shaft, makes rubber tire be turned to the last layer step.Because power arm is far longer than resistance arm, thereby very laborsaving.When dolly is done the baggage car use, there is stretching frame can make shelf be widened to 450mm, on the longitudinal edge frame of the horizontal edge frame central authorities of the handgrip cross bar central authorities of upper bracket, lower bracket and lower bracket, three securing devices are installed respectively, in securing device, penetrate two nylon restraint zones in length and breadth, restraint zone is locked fast by securing device, is used for fastening luggage.Dolly is furnished with honeycomb briquette basket, cylinder for liquefied gas pad, three annexes of cushion, as required annex is placed on the shelf, can be upstairs with the carrying of weights such as honeycomb briquette, cylinder for liquefied gas, whilst on tour can make baggage car and little stool uses, not collapsible collection of time spent, realize that folding method is: 1, support is folding.Support is divided into upper bracket and lower bracket, outside last lower bracket connects divided by having strong market potential, also has two short pin and iron wire pin joints, lower bracket is joined together, the folding iron wire that promptly connects two short pins by pulling of last lower bracket is thrown off short pin and last lower bracket, is that rotating shaft is folding then to have strong market potential.2, depression bar is folding.Depression bar divides two joints up and down, and the centre joins together with sliding sleeve, and when sliding sleeve left center-point, depression bar was promptly collapsible.3, pull bar is folding.Pull bar divides two sections, and the centre is established a little ring and connected, and can little ring be that folding point is folding with pull bar.4, shelf is folding.The shelf of placing weight are to connect with removable pin and support, shelf are up pulled can be made it superimposed with support.

The utility model has the advantages that: 1, can carry the Weight upstairs climbing below 50 kilograms, solve the walk-up worry of high residential building; 2, the many usefulness of a car can be dragged weights such as honeycomb briquette, cylinder for liquefied gas, can make baggage car, also can make little stool and use; 3, when using a kind of function, the device of other functions can remove easily; 4, collapsible collection, the not side of occupation of land.
