A quick-foldable trolley

Abstract

The invention discloses a trolley capable of being rapidly folded. The trolley comprises a main frame. Front wheels and rear wheels are installed on a front support and a rear support of the main frame respectively. A hollow lower push rod is hinged to the end, away from the rear wheels, of the rear support. An upper push rod capable of moving in a reciprocating mode along the inner wall of the lower push rod is movably installed in the lower push rod. Meanwhile, a joint lever used for being hinged to the front support is further hinged to the rear support. A connecting rod hinged to the front support and the joint lever simultaneously is arranged on the lower push rod. A first gear is fixedly arranged at the end, close to the front support, of the connecting rod. A second gear meshed with the first gear is fixedly arranged on the front support. When the trolley is folded by a person, through the meshing effect between the first gear and the second gear, the connecting rod drives the front support to rotate around the joint lever, so that the trolley is folded and contracts, the size of the folded trolley is reduced, and meanwhile the trolley is rapidly folded through folding operation at a time.

Description

technical field [0001] The invention relates to a trolley, in particular to a rapidly foldable children's trolley. Background technique [0002] Along with the development of society and the continuous progress of science and technology, various foldable children's strollers have appeared on the market.

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing children's trolleys can only fold the back bracket and push rod during the folding process, so that the volume of the children's trolley after folding is still relatively large, and it needs to occupy more space, which is not convenient for storage or transportation; in addition, There are also some children's trolleys with foldable front brackets on the market. When people fold this kind of children's trolley, they first fold the rear bracket and push rod part, and then fold the front bracket. Although the volume of this kind of children's trolley is smaller after folding, it is convenient Storage and transportation, but it needs to be folded twice, which makes the folding of this kind of children's trolley more troublesome, and brings certain inconvenience to people using this kind of children's trolley
