Description

Foldable net frame shopping trolley

The utility model discloses a kind of hand barrow, especially a kind of folding screen frame shopping cart, it belongs to operation transportation means technical field.

General shopping cart on the market all has fixedly vehicle frame, and two or four wheels, hand-pushing handles are formed.These hand barrows, the form that has is single, and the car body heaviness pushes the row effort; The complex structure that has, it is big to occupy the space, deposits inconvenience.

The purpose of this utility model is exactly the defective that will overcome above-mentioned hand-push shopping cart, designs the light hand-push shopping cart of a kind of screen frame formula.The vehicle body frame of this car is wanted to fold to dwindle, and wheel can be removed stage makeup and costume,

Reaching car body, to occupy the space little, deposits or far transport in batches purpose easily.

Task of the present utility model has following technical scheme to realize: developed a kind of folding screen frame shopping cart.This car also has two coaxial rear wheels, screen frame shape box car framework and hand-pushing handle.The utility model institute is improved to be: screen frame shape box car framework is made by preceding basket face, rear basket surface, and left bank bar basket face, right row's bar basket face and end basket face constitute five frameworks.In these five frameworks, be to be provided with some laterally hinge bars on left and right row's bar basket face.These all hinge bars cut with scissors respectively to be hung on the and arranged on left and right sides basket limit that is hinged on forward and backward basket face.Point is welded with hinge on this basket limit, both sides.Corresponding this hinge of hanging hinge with horizontal hinge bar promptly is the two ends of the horizontal basket bar on the forward and backward basket face.Each basket limit, the face left and right sides of this forward and backward basket face is the crack bar of long narrow " U " shape.This crack mid point is welded with the two ends hinge of horizontal basket bar.This forward and backward basket face then is to be welded with by point on the horizontal basket bar can constitute basket face and be corresponding all vertical basket of bars of little side's mesh shape and constitute mesh basket face.The end basket face of this frame, also be by vertical basket of bar on it respectively hook be hinged on the horizontal bottom basket strip of forward and backward basket face.Also be by vertical basket of bar and horizontal basket bar spot welding and make be basket face at the bottom of little side's mesh shape respectively.Thereby being made of with horizontal bottom basket strip and all hinges forward and backward, end basket face like this serves as that axle may be folded on together.The hand-pushing handle that this shopping cart is designed, it is long " U " shape.This both sides vertical pole tiltedly is through on left and right row's bar basket face outside, and sells solid this vertical pole respectively on the hinge bar of the top of left and right row's bar basket face by bearing pin.The bottom of this vertical pole, then by ring locking pin, pin is solid on relative bottom hinge bar.But so just constituted and tiltedly worn formula demolition hand-pushing handle.This vertical pole end stretches out left and right row's bar basket face, constitutes the front support leg that contacts to earth, and the coaxial trundle that can remove stage makeup and costume also can be installed on this leg.At this moment, trundle constitutes four-wheel screen frame shopping cart jointly with the rear wheel that can remove stage makeup and costume.

Left and right row's bar basket face of this screen frame shape shopping cart also can be made mesh basket face.Its all laterally also can be evenly equipped with the left and right basket face that the corresponding all vertical hinge bar that is linked by hinge constitutes movable little side's mesh on the hinge bar.All little side's mesh can fold for axle by its four hinge-points, thereby fold with all horizontal strokes, vertical basket bar.

When this folding screen frame shopping cart expands into the screen frame hand barrow by folded state stretching, extension dress, operate very simple, only forward and backward basket face is drawn back, make open and flat the opening of end basket face, after constituting five frameworks, again hand-pushing handle tiltedly is through at left and right row's bar basket face outside, fixes it with bearing pin and ring locking pin, install big trailing wheel at last or little front vehicle wheel is installed again, can dress up the screen frame shopping cart.
