Abstract

The invention discloses a linkage folding cart. The linkage folding cart comprises: a cart frame front rod, a cart frame rear rod, a push rod and a supporting rod, wherein the cart frame rear rod comprises a lower rear rod and an upper rear rod arranged above the lower rear rod, the upper rear rod can slide and stretch relative to the lower rear rod to make the cart frame rear rod switched betweenan extension state and a contraction state, and the rear end of the frame front rod is rotatably connected with the front end of the upper rear rod in order to make the cart frame front rod switchedbetween a first position and a second position; a connecting rod, wherein the lower end of the connecting rod is rotationally connected with the lower rear rod; and a crank, wherein the lower end of the crank is rotatably connected with the upper end of the connecting rod, the upper end of the crank is fixedly connected with the supporting rod so as to be driven by the supporting rod to rotate, and the connecting rod, the crank, the upper rear rod and the lower rear rod form a crank sliding block mechanism so as to drive the cart frame rear rod to be switched between the extension state and the contraction state when the supporting rod moves. The linkage folding cart is sufficient in driving force and low in overall height after being folded.

Description

technical field [0001] The invention relates to the technical field of trolleys, in particular to a linkage-collapsible trolley. Background technique [0002] The trolleys in the prior art are large in size and high in height after being folded, are convenient for storage and carrying after being folded, are not portable, and cannot take into account both the folding driving force and the folding height. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a linked and folded stroller, which has sufficient driving force and a low overall height after being folded. [0004] The linked and folded stroller according to the embodiment of the present invention comprises a front pole of the vehicle frame, the front pole of the vehicle frame extends obliquely upward from front to back; a rear pole of the vehicle frame, the rear pole of t...
