Being provided with steady pin while cover, be provided with split ring outside steady pin, limiting card includes intubating, middle fixture block and dial bar, and limiting card is formed in one, and intubates and is plugged on steady pin, and middle fixture block, through split ring, is dialled bar and is resisted against and determines on projection.The rotation of limiting card is limited by split ring, it is impossible to around steady pin radial rotating, be provided with torsion spring in drivening piece, and bearing pin passes torsion spring, and torsion spring two ends are separately fixed on limit lid and drivening piece.When drawing stroller in, limit lid is rotated by the moment of torsion of torsion spring, and before driving vehicle seat, arm rotates, and safety rail is drawn close automatically.
As preferably, including handle tube, also including the ejector sleeve being hinged on handle tube lower end, ejector sleeve lower end is fixedly connected with bend pipe, and ejector sleeve is formed in one with bend pipe, bend pipe lower end is hinged on trailing wheel arm, being fixed with pull bar on ejector sleeve, front-wheel arm is hinged with first connecting rod, pull bar is hinged with first connecting rod, being hinged with third connecting rod on described ejector sleeve, third connecting rod is hinged with fourth link.
As preferably, also including second connecting rod, one end of second connecting rod is hinged on bend pipe, and the other end of second connecting rod and first connecting rod, pull bar are articulated with same point.
As preferably, also including that side lever, the upper end thereof of side block bar have slide block, handle tube passes slide block.
As preferably, described third connecting rod is provided with recess.In after vehicle seat, arm is resisted against the recess of third connecting rod.
Gripping handle tube comes closer, and centered by the ejector sleeve hinged place with trailing wheel arm, ejector sleeve rotates down, and drives pull bar to rotate with first connecting rod, and front-wheel arm rear wheel arm is drawn close.Third connecting rod, fourth link are pulled simultaneously, and third connecting rod, fourth link pull drivening piece to rotate, and torsion spring drives limit lid also to rotate simultaneously, safety rail with and automatically draw close.When launch stroller time, limiting card and determine between projection unlock, thus safety rail expansion.
This utility model, owing to have employed above technical scheme, only need to press the switch at bar top, and stroller can easily fold, simple to operate, and safety rail also can be drawn close automatically simultaneously, more decreases the volume after folding of baby.
