Description
Technical field
The utility model relates to a kind of Foldable baby stroller.
Background technology
Existing doll carriage comprises front-wheel support, is arranged on the front component of front-wheel support front lower place, rear wheel support, the pulling handle rod that is arranged on the wheel assembly of the rear wheel support back lower place and is rotatably connected on the rear wheel support leading section, the rear end of front-wheel support is connected with sliding sleeve, sliding sleeve is enclosed within on the rear wheel support, be connected with connecting rod between pulling handle rod and the sliding sleeve, vehicle frame is when deployed condition, slide over and move to the extreme higher position on the rear wheel support, and locked by the blocking device on the rear wheel support.
Above-mentioned doll carriage is in folding process, as long as to downward power of pulling handle rod, the front end that the leading section of pulling handle rod will drive rear wheel support moves to the front lower place, slide over the rear end that also can slide to rear wheel support under the effect of connecting rod, just can realize the above-below direction size decreases with regard to car load in folding back like this, though this folding mode is easy to operate, but after car load is folding, the size of fore-and-aft direction can not diminish, therefore still there is the bigger problem of volume after folding, can't fundamentally dwindles packaging volume.
Summary of the invention
The utility model purpose is: a kind of Foldable baby stroller is provided, and when it was folding, the contracting backward foremost of front-wheel support made the length of fore-and-aft direction of go-cart diminish, and then reduces packaging volume.
The technical solution of the utility model is: a kind of Foldable baby stroller, comprise front-wheel support, be arranged on the front component of front-wheel support front lower place, rear wheel support, be arranged on the wheel assembly of the rear wheel support back lower place and be rotatably connected on the pulling handle rod of rear wheel support leading section, described rear wheel support is provided with can be along the sliding part of rear wheel support slip, be connected with connecting rod between sliding part and the pulling handle rod, described rear wheel support is provided with the blocking device that is used for lock slide, described front-wheel support comprises that at least front and back are to the preceding arm that extends, be connected with the back arm that extends forward on the sliding part, arm and back arm sliding block joint before described, be connected with attaching parts on the arm of described back, be connected with bottom tie rod between attaching parts and the front-wheel support, also be connected with back stay between described attaching parts and the rear wheel support.Wherein, described back arm is an outer tube, sliding block joint with it also on the arm before back arm is set in.
Described rear wheel support has two, and described sliding part is two sliding sleeves that are set on two rear wheel supports, and the rear end of described back arm is installed with a rear transverse rod, and this rear transverse rod is installed between two sliding sleeves.Described connecting rod has two, and the difference pin joint is between two sliding sleeves and pulling handle rod both sides.Described back stay has two and be front end is low, the rear end is high bend pipe, the front end of two back stays respectively pin joint in the left and right sides of attaching parts, the rear end respectively with the anterior pin joint of two rear wheel supports.
Described attaching parts is the crescent of opening to the front upper place, thereafter termination and back arm pin joint, front end and bottom tie rod pin joint, bending place, middle part and back stay pin joint.
Described rear wheel support is provided with blocking device, and vehicle frame is when deployed condition, and sliding part slides to the rear wheel support middle front part, and the locking of locked device, and this blocking device can be by the folding handle control release on the pulling handle rod.Above-mentioned blocking device consistent with described in the publication number CN200954826 Foldable baby stroller patent, so its concrete structure does not specify in the utility model.
When the utility model folds, on carry folding handle on the pulling handle rod, folding handle drives blocking device sliding part is realized release, give downward power of pulling handle rod simultaneously, the front end that the leading section of pulling handle rod drives rear wheel support moves to the front lower place, sliding part slides to the rear end of rear wheel support under the effect of connecting rod, this moment attaching parts under the effect of back stay around and the rotating shaft of back between the arm rotate backward, front-wheel support then moves after under the effect of bottom tie rod, even preceding arm inserts the back arm backward, just can realize diminishing in above-below direction size and the fore-and-aft direction size in folding back with regard to car load like this, dwindled the volume after car load is folding greatly, reduce packing cost, reduced occupation space when depositing.
The utility model can be three wheel barrows, also can be the four-wheel go-cart, if front-wheel support only comprises front and back to the preceding arm (being that front-wheel support is preceding arm) that extends, and the front lower place of arm before a front component is installed in, promptly car load is three wheel barrows; If in the preceding arm that extends, to the front rail that extends, that needs only the left and right sides that two front components is installed in front rail to front-wheel support about preceding arm front end sets firmly before and after having, promptly car load is the four-wheel go-cart.
The utility model has the advantages that: the utility model just can be realized diminishing in above-below direction size and the fore-and-aft direction size in folding back, has dwindled the volume after car load is folding greatly, has reduced packing cost, has reduced occupation space when depositing.
