Summary of the invention

The utility model problem to be solved is, to the deficiency of prior art, designs a kind of simple in structure, folding convenient, the little lightweight collapsible shopping cart of volume after folding.

The technical scheme that the utility model is taked is:

A kind of collapsible shopping cart; Comprise that hand push holds up bar, forms basket vehicle frame, is positioned at the underframe of vehicle frame below; Said vehicle frame by many from top to bottom arrangement in parallel " mouth " glyph framework be positioned at the bottom carriage form; The front and back of said framework is hinged with forward and backward pole respectively, and underframe comprises the wheel and the bracing frame that is positioned at bottom outside of bottom inside, and the main shaft of wheel is connected with back stay; Bracing frame comprises the strut bar that withstands on carriage below and the feet of fixing branch strut, and an end of feet is hinged on the vehicle frame.

In the present embodiment, said framework is divided into forward and backward cross bar and the left and right cross bar that is " C " font, and the end of said forward and backward cross bar is connected with forward and backward pole, on the hinged forward and backward pole in the end of left and right cross bar.

In the present embodiment, the top of said vehicle frame is provided with bracket, and the rear side of bracket is hinged on the back stay, and bracket connects to ground through hook.

In the present embodiment, said hand push holds up the upper articulation of bar in the both sides of the framework of the top, and its below is connected with feet, and feet passes through pipe link and is connected with framework.

In the present embodiment, said hand push holds up bar to be connected with back stay.

In the present embodiment, the upper half of feet, connect to form four-bar linkage through revolute pair between the most following half and the connecting rod of back half, the back stay of the framework of below.

In the present embodiment, be connected with cardan wheel below the said feet.

The beneficial effect of the utility model is: the basket vehicle frame of the utility model by many from top to bottom arrangement in parallel " mouth " glyph framework be positioned at the bottom carriage form; Framework, only needs front support rod is up carried during use through forward and backward strut fixation moulding; Can whole vehicle frame upwards be folded up; Convenient and simple for operation, dwindled 2/3rds before the volume ratio after folding is folding, saved the occupation of land space widely.And still contact at folding rear wheel with ground, unaffected, make the shopping cart after folding still can promote or drag walking.
