Description

Foldable baby stroller

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;

2. body frame structure for automotive more complicated, a plurality of cross bars about being fastened between two vehicle frames can produce more interference when folding, use 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 solution of the utility model is: a kind of Foldable baby stroller, comprise and taking the shape of the letter U, opening lower supporter and front frame backward, lower supporter comprises end plastic and vertical pin joint arm at the bottom of two on the end plastic of front end, the rear end of the bottom of end plastic and end arm is separately installed with wheel, front frame comprises preceding plastic and vertical two the preceding arms of pin joint on preceding plastic of front end, end plastic and the horizontal pin joint of preceding plastic, the rear end of two preceding arms is connected with push rod by upper joint respectively, 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, locking piece can be locked by the lockout mechanism in the push rod, the front end of push rod is rotatably connected to hypozygal, the middle part of end arm is rotatably connected to joint, the end, be connected with the folding strut of X type between two hypozygals and the joint, two ends, the folding strut of described X type is by forming to pin joint before and after two strut bars middle parts.

Described push rod is the hollow rods of front opening, described 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, 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 the folding handle that sliding part is connected and fixed, push rod is provided with for folding the mounting hole that handle slides, and described locking piece is provided with the lock slots that can supply dead bolt to insert and lock.

Described hypozygal be about to the ground pin joint at the push rod front end, the upper end of strut bar be before and after to the ground pin joint on hypozygal.About joint, the described end to the ground pin joint on the fabricated section of end arm, this joint, end is overlooked and is the U type, before and after the lower end of its two lateral plate and strut bar to the ground pin joint.

The upper end of described two push rods is connected with the push rod attaching parts respectively, is connected with folding handle between the two push rod attaching partss, and folding handle is formed by left folding pulling handle rod and right folding pulling handle rod pin joint.

When folding, apply a downward power F to folding handle, the pin joint portion of left folding pulling handle rod and right folding pulling handle rod is bent downwards, carry the folding handle of push rod both sides on again, folding handle drives traction lock by 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.

During expansion, 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, carry the pin joint portion of left folding pulling handle rod and right folding pulling handle rod again, folding handle is launched fully, vehicle frame was promptly launched fully and was locked this moment.

When vehicle frame folding and expansion, push rod and preceding arm rotate around pin between the two, and preceding arm and end arm rotate around the pin between preceding plastic and the end plastic, and under the effect of folding strut of X type and folding handle, the two-way of car load vehicle frame folds.

The utility model has the advantages that:

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 lower supporter of the present utility model and front frame all are the U type, and only utilize the folding strut pin joint of that X type to connect the horizontal interference when having avoided folding between lower supporter and the front frame.
