Description

Foldable pushchair

Technical field

This utility model relates to stroller, has particularly related to a kind of foldable pushchair.

Background technology

The most increasing stroller is with folding functional, after folding of baby, volume is greatly reduced, conveniently store and the vehicles can be put into and carry, but its volume is bigger than normal after folding of baby of the prior art, or the process very complicated of folding operation, needing to expend large force gas, this is inconvenient for for the young mother taken the kids with.Stroller the most of the prior art, in order to save volume, scarcely has the safety rail stopping child, and this may cause child's landing from stroller, there is potential safety hazard.

Summary of the invention

This utility model is for the shortcoming of folding of baby process very complicated in prior art, it is provided that a kind of novel foldable pushchair.

In order to solve above-mentioned technical problem, this utility model is addressed by following technical proposals:

Foldable pushchair, including handle tube, front-wheel arm and trailing wheel arm, also include the ejector sleeve being hinged on handle tube lower end, ejector sleeve lower end is fixedly connected 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.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.

As preferably, ejector sleeve is formed in one with bend pipe.

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 include before vehicle seat arm after arm and vehicle seat, safety rail it is fixed with on arm before vehicle seat, being hinged with third connecting rod on described ejector sleeve, third connecting rod is hinged with fourth link, and before vehicle seat, one end of arm is fixed with limit lid, one end of fourth link is fixed with drivening piece, being fixed with transmission projection while cover, drivening piece is provided with containing cavity, and transmission projection stretches in containing cavity.Ejector sleeve rotates down, and pulls third connecting rod, fourth link, third connecting rod, fourth link to pull drivening piece to rotate.

As preferably, the outer wall of limit lid is provided with limiting card, and front-wheel arm upper end is fixed with barrel member, and the center of described barrel member is provided with bearing pin, and bearing pin stretches in drivening piece, the outer wall of barrel member is fixed with and determines projection, determines projection for limiting the rotation of limiting card.When safety rail rotates outside stroller, the limit lid being fixedly linked with safety rail also with rotation, while the limiting card covered turn an angle after by determining the spacing of projection, make rotation stop, thus define the rotational angle range of safety rail.

As preferably, 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.

As preferably, being provided with torsion spring in drivening piece, 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, also including that side block bar, 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.

This utility model, owing to have employed above technical scheme, only need to press the switch at bar top, and stroller can fold and launch, simple to operation, simultaneously safety rail also can automatic deploying and retracting, more decrease the volume after folding of baby.
