Abstract
The utility model discloses a baby stroller, a stroller frame is provided with a rod element, lateral armrests, a cover connector rotary rod, an inner cover rod and a front cover rod. When the unfolded stroller frame is converted to a folding status, the rod element and the lateral armrests are closed. A synchronous mechanism which enables the lateral armrests to rotate backwards to further drive the cover connector rotary rod to rotate backwards is arranged between each lateral armrest and the cover connector rotary rod. The rod element is fixed with a fixed cover rod which is connected with a cloth cover, and when the stroller frame is unfolded, the fixed cover rod is disposed at the rear of the inner cover rod. Further, an elastic element for providing backward elastic return force to the inner cover rod is arranged between the end portion of the inner cover rod and the cover connector rotary rod. When the stroller is folded, the cloth cover between the fixed cover rod and the inner cover rod can pull the inner cover rod to close to the front cover rod, thereby realizing automatic closure of the cloth cover.
Description
Technical field
The utility model relates to a kind of children trolley.
Background technology
In the children trolley, there is the go-cart vehicle frame of open mode and folded state to have pulling handle rod, the side handrail that rotates and be provided with pulling handle rod, the paulin joint bull stick that rotates and be provided with side handrail, the interior tarpaulin rod that one end and paulin joint bull stick rotate and be provided with, be located on the paulin joint bull stick and be positioned at the preceding tarpaulin rod in tarpaulin rod the place ahead, when the go-cart vehicle frame from open mode when folded state is changed, rod member and side handrail are folded, rod member rotates forward, side handrail rotates backward, side handrail, be provided with between the paulin joint bull stick and be used to make rotating backward of side handrail to drive the synchronizer gear that paulin joint bull stick rotates backward, preceding tarpaulin rod, be connected with the cloth cover that is used to block between the interior tarpaulin rod, in the prior art, be provided with lockout mechanism between interior tarpaulin rod and the paulin joint bull stick, lockout mechanism comprises a plurality of perforates that are opened on the paulin joint bull stick, be used to insert a plurality of projections in the perforate in being located on the tarpaulin rod, a plurality of perforates, a plurality of projections are that the circumferencial direction at center is spaced successively along the turning cylinder that rotates with interior tarpaulin rod and paulin joint bull stick all, then by tarpaulin rod in firmly rotating, make projection and perforate be separated, after interior tarpaulin rod turned over an angle, the projection on the interior tarpaulin rod can insert in the perforate once more.When the go-cart vehicle frame folding, as the common go-cart vehicle frame of those skilled in the art, pulling handle rod moves downward, the drive side handrail rotates backward, thereby paulin joint bull stick also rotates backward, and goes to the rear of pulling handle rod, and the cloth cover that is drawn in also is positioned at the rear of pulling handle rod, owing to all be positioned at the place ahead of pulling handle rod after most of rod member of go-cart vehicle frame is folded, then the layout of folding pusher vehicle carriage is better.Main rod member on the go-cart vehicle frame finish folding after, in stirring tarpaulin rod forward tarpaulin rod draw close drawing the cloth cover in owing to will overcome the resistance that projection and perforate are separated, then above-mentioned manual gathering cloth cover operation is relatively required great effort.
Summary of the invention
The children trolley of cloth cover after being to provide a kind of go-cart vehicle frame to be folded, the purpose of this utility model can be provided in automatically.
