Description
Technical field
The present invention relates to a kind of baby carriage, in particular to a kind of collapsible convenient trolley of collapsible children.
Background technique
The convenient trolley of collapsible children generally includes forward support post and rear support strut, forward support post and rear support strut it
Between at one position of the centre of support column by lateral shaft connection, form X-shaped interconnection, forward support post is from top to bottom from can
The rear of the convenient trolley of the children folded extends to the front of the convenient trolley of collapsible children, and forward support post is collapsible
The rear portion of the convenient trolley of children extend to form trammer handle；Rear support strut is from top to bottom from the collapsible convenient hand push of children
The rear of the convenient trolley of collapsible children is extended in front of vehicle, movable pulley is arranged in the lower end of every support column；Described
Shaft enables to be overlapped when the collapsible convenient trolley of children folds in same plane between forward support post and rear support strut
Or close in same plane, convenient for reducing the volume after the collapsible convenient trolley of children folds；In the top of the shaft
Equipped with seat board, it is equipped with seat board shaft between the front and rear support strut of seat board, is formed and is rotatablely connected by seat board shaft, front support
A lateral supporting beam is equipped at column respective seat postlaminar part, when the collapsible convenient trolley of children is unfolded, the rear end of seat board
It is supported the support of beam, so that seat board is supported, children are ridden on seat board.
Disadvantage of the prior art is that: supporting beam must be horizontally through forward support post, so that forward support post is at seat board position
Structural intergrity destroyed, intensity decline, usual center of gravity is pressed in the rear portion of seat board, Yi Zao when children are sitting on trolley
At forward support post deformation or damage, especially after being impacted；The supporting beam is due to being transverse to forward support post, so that branch
The end of support beam protrudes from the surface of forward support post, forms overhanging girder construction, easily bends under the pressure of seat board, it is necessary to have
There are enough section carrying sizes, this further influences the structural intergrity of forward support post in turn.
Summary of the invention
The present invention is in order to overcome above-mentioned defect in the prior art, by being socketed sliding ring outside forward support post, by seat
The rear portion of plate is rotatably coupled with sliding ring, and the support ring fixed in the external setting of forward support post so that sliding ring with
Support ring abuts against, it is ensured that the bearing capacity of seat board acts in the axial direction of forward support post, it is ensured that forward support post is in carrying seat board
Structural integrity is kept at position, and there is stable support effect.
To achieve the above object, the present invention provides a kind of collapsible convenient trolley of children, including support column, support column
Including front support and rear support strut, pass through lateral shaft at one position of the centre of support column between forward support post and rear support strut
X-shaped interconnection is formed, forward support post extends to from the rear of the collapsible convenient trolley of children collapsible from top to bottom
The upper end in the front of the convenient trolley of children, forward support post is equipped with trammer handle；Rear support strut is from top to bottom from collapsible youngster
The rear of the convenient trolley of collapsible children is extended in front of boys' urine victory trolley；Movable pulley is arranged in the lower end of support column,
