Technical field

the utility model relates to a kind of Foldable baby stroller.

Background technology

Doll carriage in the market generally includes the vehicle frame that handbag or bicycle basket or seat are installed; Vehicle frame comprises front component, wheel assembly, two sidecar framves that are symmetrical set and is connected a plurality of cross bars between the vehicle frame of both sides; Each sidecar frame comprises front frame, after poppet and push rod, and vehicle frame can locking when launching to use.The shortcoming of this type of go-cart has:

1. integral structure is essentially left and right sides two-piece type vehicle frame, when folding can only before and after folding, and can not about folding, the volume after folding is still bigger, is not easy to place and carry;

are the body frame structure for automotive more complicated 2., and a plurality of cross bars about being fastened between two vehicle frames can produce more interference when folding, uses trouble.

Summary of the invention

the utility model purpose is: provide a kind of can before and after folding and about folding Foldable baby stroller; Its car load rod member is less; Produce too much interference when having avoided folding, and the volume after folding is less, it is also comparatively convenient to lay and carry.

The technical scheme of the utility model is: a kind of Foldable baby stroller; Comprise front component, wheel assembly, have the folding strut of push-rod assembly, U-shaped front frame assembly and X type of lockout mechanism; Said push-rod assembly comprises two push rods and the handle of pin joint between two push rods, and said front frame assembly comprises attaching parts and the pin joint of front end two preceding arms in the attaching parts both sides, and the rear end of two preceding arms is respectively through upper joint and push rod pin joint; The front end of push rod extends and is positioned at the bottom of preceding arm forward; Preceding arm is provided with locking piece corresponding to the front end of push rod, and locking piece can be by the locking of the lockout mechanism in the push-rod assembly, and the front end of push rod is rotatably connected to hypozygal; Two upper ends of the folding strut of left and right sides hypozygal and X type are pin joint respectively; Said two wheel assemblies are pinned at two lower ends of the folding strut of X type respectively, are connected with bottom supporting rod between the infall of the folding strut of said X type and the attaching parts, and said front component is connected in the front lower place of bottom supporting rod.

above-mentioned handle can be the handle of one-part form, also can be the folding handle of two sectional type, and folding handle is formed by left folding pulling handle rod and right folding pulling handle rod pin joint.

said push rod is the hollow rods of front opening; Said lockout mechanism comprises the dead bolt that is positioned at the push rod front port; Be provided with stage clip between the pin of dead bolt and push rod inner chamber, the rear end of dead bolt is connected with traction lock, and the rear end of traction lock is connected with folding sliding part; Folding sliding part is positioned at the rear portion inner chamber of push rod; The outside of push rod is provided with and folds sliding part and be connected fixing folding handle, and push rod is provided with the mounting hole that supplies folding handle to slide, and said locking piece is provided with and can supplies dead bolt to insert and the lock slots of locking.Have an oblong pilot hole on the said dead bolt, the push rod inner chamber be provided be located in this pilot hole and with the fixing guide finger of push rod.

When fold, on carry the folding handle of push rod both sides, folding handle drives traction lock through folding sliding part; Under the drive of traction lock; Dead bolt upwards slides, and when folding handle was mentioned topmost, dead bolt shifted out from the lock slots of locking piece fully; Apply forward a power to push rod this moment, and vehicle frame can draw in.

When launch , lift push rod, when the dead bolt of push rod below and the locking piece on the preceding arm suit fully; Under the pressure effect of stage clip; Dead bolt slips into and is fastened in the lock slots of locking piece, carries handle on again, and vehicle frame was promptly launched fully and locked this moment.

are when vehicle frame folding and expansion; Push rod and preceding arm rotate around pin between the two; Preceding arm and attaching parts rotate around pin between the two, and bottom supporting rod and attaching parts rotate around pin between the two, and the folding strut of bottom supporting rod and X type rotates around pin between the two; Under the effect of folding strut of X type and push-rod assembly, the two-way of car load vehicle frame folds simultaneously.

The utility model has the advantages that:

1. the utility model can not only before and after folding, and can also about folding, the volume after folding is littler, lays and carry more convenient.

2. because the utility model simple in structure, laterally link is less, the horizontal interference when having avoided folding.
