Description

stroller

technical field

The invention relates to a baby carriage.

Background technique

Traditional strollers generally include a foldable frame, wheels arranged under the frame, and a locking mechanism arranged on the frame for controlling the frame. The traditional frame includes two symmetrical side brackets on the left and right sides and a lateral The horizontal link connecting the two side brackets achieves the effect of folding the car body through the folding of the side brackets. The side brackets generally include push rods, side armrests, front wheel brackets and rear wheel brackets. The front wheel brackets and rear wheel brackets There is a seat rod between them, and the seat rod extends to the rear to form a basket rod. In this way, if you want to make the basket rod longer to hang a larger basket for placing sundries, the length of the seat rod will be changed. If it is too large, it is inconvenient to fold the whole frame.

Contents of the invention

The object of the present invention is to avoid the above-mentioned problems and provide a stroller with a simple frame folding structure and a larger basket rod.

In order to achieve the above object, the technical solution adopted by the present invention is: a baby carriage, which includes two side brackets on the left and right sides and a transverse connecting rod transversely connecting the two side brackets, each of the side brackets includes a push rod , side armrests, front wheel brackets, rear wheel brackets, seat bars, connecting rods and basket bars, front wheels are arranged below the front wheel brackets, rear wheels are arranged below the rear wheel brackets , the push rod is pivotally connected to the rear end of the side armrest through the first rotating shaft, the upper end of the front wheel bracket and the upper end of the rear wheel bracket are respectively connected to the The front part of the side armrest is pivotally connected, the front end of the seat cushion bar is pivotally connected to the front wheel bracket through the fifth rotation axis, and the rear end of the seat cushion bar is connected to the The front end of the basket rod is pivotally connected through the sixth rotation axis, the front end of the basket rod and the connecting rod is pivotally connected through the seventh rotation shaft, and the rear end of the connecting rod The push rod is pivotally connected with the push rod through the third rotation shaft, the connecting rod is pivotally connected with the rear wheel support through the fourth rotation shaft, and the seventh rotation shaft and the sixth rotation shaft are both located at the front between the wheel bracket and the rear wheel bracket.

Each of the side brackets also includes a connecting support, one end of the connecting support is pivotally connected to the rear wheel bracket through the eighth rotating shaft, and the other end of the connecting support is connected to the The basket rod is pivotally connected by the ninth rotation axis, the eighth rotation axis is located on the lower side of the fourth rotation axis, and the ninth rotation axis is located behind the seventh rotation axis. side.

The invention has the following advantages: since the seat cushion rod and the basket rod are separately arranged, the basket rod can be set relatively long, so that a larger basket can be hung; in addition, the whole vehicle frame has a simple structure and is convenient to fold.
