Folding frame of baby stroller

Abstract

The invention discloses a folding frame of a baby stroller. The folding frame comprises a front foot pipe, a rear foot pipe, handlebar straight pipes, a handlebar bent pipe, a mounting piece and the like, and further includes a front supporting pipe and a rear supporting pipe which are transversely installed in the frame, and a seat platform connected between the front supporting pipe and the rearsupporting pipe in a rotating mode. The lower ends of the two handle straight pipes are respectively mounted in the two mounting pieces in a synchronous lifting and sliding manner; the two ends of the front supporting pipe are installed at the lower ends of the two handle straight pipes in a sliding mode in the axial direction respectively, the two ends of the rear supporting pipe are hinged to the two supporting legs of the U-shaped rear foot pipe respectively, and hinged connecting rods are arranged between the lower end of each handle straight pipe and the supporting legs on the same sideof the rear foot pipe. A first locking piece and a second locking piece are further arranged on the mounting piece, the first locking piece locks or unlocks sliding of the lower ends of the handle straight pipes, and the second locking piece locks or unlocks sliding of the end of the front supporting pipe; therefore, through the structural improvement, unfolding or folding of the frame can be better achieved, and the folding frame has the advantages of being simple in design, easy to operate, small in size after being folded and the like.

Description

technical field [0001] The invention relates to a foldable frame of a stroller, in particular to a foldable frame of a baby stroller. Background technique [0002] At present, the expanded use state and the folded storage state of the baby stroller are mainly realized by the folding frame that constitutes the skeleton of the baby stroller. The U-shaped ends of the front leg tube are respectively equipped with fixed installation parts, and the U-shaped ends of the rear leg tube and the lower ends of the two handle bends are respectively rotatable and hinged on the two ends. Then the entire frame is unfolded to form an inverted Y shape, and then a separate detachable seat is installed between the two mounting parts, which is a connecting part for the front and rear tubes to rotate or fold each other. , its height is usually limited by a certain structure, which will cause the seat to be installed too low, which will affect the baby's sight when riding, and it will be closer t...

Problems solved by technology

[0002] At present, the expanded use state and the folded and stored state of the baby stroller are mainly realized by the folding frame that constitutes the skeleton of the baby stroller. The U-shaped ends of the front leg tube are respectively equipped with fixed installation parts, and the U-shaped ends of the rear leg tube and the lower ends of the two handle bends are respectively rotatable and hinged on the two ends. Then the entire frame is unfolded to form an inverted Y shape, and then a separate detachable seat is installed between the two mounting parts, which is a connecting part for the front and rear tubes to rotate or fold each other. , its height is usually limited by certain structures, which will cause the seat to be installed too low, which will affect the baby's sight when riding, and it will be closer to the dust on the ground and farther away from the mother; at the same time, the front leg tube, rear leg tube and handle When the inverted Y-shaped frame composed of bent pipes is unfolded or folded, it is realized by the rotation around the mounting parts. In order to ensure the stability and reliability of the unfolded state or the folded state, it is necessary to ensure the stability and reliability between these three parts. More connecting rods are designed, so the structure will be more complicated and the operation will be more difficult. Not only will the frame become larger after folding, especially the length direction will appear longer, but also the weight will be heavier, which will affect portability.
