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

Background technology

In the prior art, State Intellectual Property Office has announced a key name on September 5th, 2007 and has been called " Foldable baby stroller ", the patent No. is the utility model patent of " ZL200620076331.4 ", this patent " discloses a kind of Foldable baby stroller; it is characterized in that: comprise taking the shape of the letter U; opening lower supporter and front frame backward; lower supporter comprises the end plastic of front end and vertical pin joint arm at the bottom of two on the end plastic; the rear end of the bottom of end plastic and end arm is separately installed with wheel; front frame comprises the preceding plastic of front end and vertical two preceding arms of pin joint on preceding plastic, 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 leading portion of push rod extends and is positioned at the bottom of preceding arm forward, the front end of push rod is provided with the locking of hypozygal and preceding arm, is connected with the X-shaped bracing frame between two hypozygals and the end arm; This go-cart can not only before and after folding, and can also about folding, the volume after folding is littler, the interference when folding is still less laid and carries more convenient.”

Find that in actual use the X-shaped bracing frame can be to laterally opening under the compressing of infant weight, and vertically highly decline, thereby the height that can cause front frame descends gradually, sometimes even can have influence on user's normal use.

Summary of the invention

The utility model purpose is: a kind of Foldable baby stroller is provided, between front frame and lower supporter, increased strut bar, and the X-shaped support improved, make whole go-cart when launching to use, possess enough bearing forces, avoid occurring the car load bearing height defective that descends gradually.

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, be connected with collapsible bottom supporting rod at the bottom of two between the arm, 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, be connected with handle between the rear end of two push rods, the front end of push rod is extended with protrusive rod forward, protrusive rod below the preceding arm and and preceding arm between be provided with lockout mechanism, the front end of described protrusive rod is provided with hypozygal, two hypozygals are connected with strut bar respectively and between the end arm of homonymy, and be connected with the X-shaped support between two strut bars, be connected with boxed rod respectively between two upper ends of X-shaped support and the strut bar.

In the technique scheme, plastic is extended with upper protruding block to the back upper place before described, be connected with two foundation connecting rods between upper protruding block and the collapsible bottom supporting rod, the rear end of two foundation connecting rods pin joint respectively makes that two foundation connecting rods are V-shaped backward to be opened on about collapsible bottom supporting rod two sections.

The utility model advantage is:

1. the utility model has increased strut bar between front frame and lower supporter, and the X-shaped support is improved, and makes whole go-cart possess enough bearing forces when launch using, and avoids occurring the car load bearing height defective that descends gradually.

2. the utility model is connected with boxed rod respectively between two upper ends of X-shaped support and strut bar, makes strut bar and the X-shaped support can be folding and not be restricted when launching.
