Description

A kind of Foldable pushcart

(1) technical field

The utility model relates to a kind of transportation means of logistics, particularly relates to a kind of structure of portage hand barrow.

(2) background technology

Along with the development of commodity economy, logistics system and abundant, people have more and more be unable to do without small-sized hand barrow.Hand barrow has various specifications, form, according to the different specification of volume and weight use of bearing goods.

There is following deficiency in prior art,

Have that conveying goods of hand barrow be not to fix, sometimes volume is less, only need the less long-pending hand barrow of object plane that holds, and need the article of the hand barrow of big cargo area sometimes for delivery larger volume, area, for this reason, if be equipped with the accumulation that the hand barrow of two kinds of specifications will cause the instrument of transporting, be a kind of waste of resource, if have only a kind of hand barrow of specification, can not satisfy the needs of different occasions again.

In addition, some hand barrow volume is big, Heavy Weight, is not easy to carry, and people have also proposed to wish energy reduced volume, portable requirement.

For this reason, market has proposed a kind of new requirement, and hope can provide a kind of structure of hand barrow, reaches the purpose that is satisfied different occasion needs by a kind of vehicle of specification, and perfect condition is simultaneously, can obtain in the use than large tracts of land load, again can be more convenient when carrying.

(3) utility model content

The purpose of this utility model is to provide a kind of energy to be suitable for the trolley structure of different loading volumes, area.

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

A kind of Foldable pushcart comprises trammer handle, and wheel is installed in the bottom, overlooks rectangular plateform body, it is characterized in that, one side handle with being connected of pivot pin structure and plateform body, the another side of plateform body is with hinge arrangement connection one vehicle body that extends.

The technical program, one side handle with being connected of pivot pin structure and plateform body, folding handle as required dwindles the height and the space of hand barrow, is easy to carry and places.The another side of plateform body connects a lengthening vehicle body with hinge arrangement, can open the lengthening vehicle body or foldingly close up the lengthening vehicle body according to how many decisions that push goods, and loading is more suitable, pushes more flexible; Close up after finishing using, floor area is little.

Described lengthening vehicle body and plateform body width, length are identical.

Two wheels are installed in the bottom of described lengthening vehicle body, and wheel is near a side that does not hinge.

A wheel is installed in the bottom of described lengthening vehicle body, and wheel is near the center of symmetry of the side that do not hinge.

Described lengthening vehicle body and plateform body junction are drawn and are buckled secondaryly with the corresponding side of hinge torsion spring being set, and promptly are provided with one one and draw button by what torsion spring was pulled, on another person relevant position, offer and draw catching groove.Adopt the technical program, lengthening vehicle body and plateform body fasten mutually and are an integral body opening Shi Youla button parafacies, and both connect firmly when using loading, and are oppressed by torsion spring and to draw button, operate more automatic light.

Described torsion spring draws that button is secondary each side to be provided with a pair at vehicle body, and left and right draw to buckle add interconnective cross bar.Left and right draw buckle add interconnective cross bar after, step on cross bar, about draw link moving, easy to use.

Described handle is connected with plateform body with the pivot pin structure, at the pivot pin sidepiece spring holder is set, and the locating dowel pin by the spring compressing promptly is set on handle or vehicle body, offers the knock hole of relevant position on vehicle body or handle.At the pivot pin sidepiece spring holder is set, knock hole is inserted by spring compressing locating dowel pin in two positions that the energy fixed handle is opened on plateform body or closed up, and degree of automation improves, and is easy to operate.

Described spring holder is arranged on the left and right sides of handle, and adds drag-line between the left and right locating dowel pin.Add drag-line can interlock about two locating dowel pins pull out more convenient operation simultaneously.

The wheel of described lengthening body bottom is a cardan wheel.

The beneficial effects of the utility model find expression in: one side handle being connected with pivot pin structure and plateform body, the another side of plateform body connects a lengthening vehicle body with hinge arrangement, folding handle as required, lengthening vehicle body or the folding lengthening vehicle body that closes up are opened in decision, loading is more suitable, push more flexibly, floor area is little, and is easy to carry.Lengthening vehicle body and plateform body junction are provided with torsion spring and draw button secondary, and the handle body contact is provided with spring holder, and degree of automation improves, and is easy to operate.
