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

Embodiment Construction

[0022] refer to Figure 1 to Figure 9 , a fast foldable trolley, comprising a frame body 1, a front wheel 110 and a rear wheel 120 are respectively installed on the front frame 11 and the rear frame 12 of the frame body 1, and the rear frame 12 is far away from the rear wheel 120 One end is hinged with a hollow lower push rod 13, and an upper push rod 14 that can move back and forth along the inner wall of the lower push rod 13 is movably installed in the lower push rod 13. Here, the lower push rod 13 and the upper push rod 14 are preferably A telescoping sleeve, so the lower push rod 13 and the upper push rod 14 form the push rod part of the handcart of the present invention, while the rear support 12 is also hinged with a connecting rod 17 for being hinged with the front support 11, The lower push rod 13 is provided with a connecting rod 15 that is hinged with the front bracket 11 and the connecting rod 17 at the same time, that is, the front bracket 11, the connecting rod 1...

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. These baby trolleys are easy to use. When traveling, the caregiver can place the baby or child in the baby stroller without the need for the caregiver to hold or carry the baby or child for a long time, which greatly reduces the burden on the caregiver. Trolleys are extremely popular. [0003] However, most of the existing children's trolleys can only fold the rear bracket and push rod during the folding process, so that the folded volume of the children's trolley 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....
