Abstract
The utility model discloses a folding and rotating structure of a baby stroller. The structure comprises a first connecting element and a second connecting element which are in connection with each other through a pin shaft. A pin connection part of the second connecting element is provided with a clamping pin on one side of the pin shaft, and the pin connection part of the first connecting element is provided with an arc-shaped groove used for embedding of the clamping pin and matching with the clamping pin in a sliding mode. By means of sliding match of the second connecting element and the first connecting element through the clamping pin and the arc-shaped groove, folding travel control between the first connecting element and the second connecting element is achieved, and folding of the whole baby stroller is achieved.
Description
Technical field
The utility model relates to a kind of doll carriage.
Background technology
The mode that connects by the attaching parts pin joint between many parts in the existing doll carriage to be realizing relatively rotating between the two, and then realizes that car load is folding.For example, the upper end of the front arm of some vehicle frame can set firmly the first attaching parts, and the lower end of push rod can set firmly the second attaching parts, the first attaching parts be connected the attaching parts pin joint and connect so that during vehicle frame folding, push rod can draw in relatively with front arm.But this simple pin joint also has the following disadvantages, and its folding stroke is uncontrollable.
Summary of the invention
The utility model purpose is: a kind of folding rotational structure of doll carriage is provided, and its second attaching parts and the first attaching parts are realized between the two folding Stroke Control by the bearing fit of bayonet lock and deep-slotted chip breaker, and then realize that better car load is folding.
The technical solution of the utility model is: a kind of folding rotational structure of doll carriage, comprise by the bearing pin pin joint and connect the first attaching parts and the second attaching parts, the pin joint section of described the second attaching parts is provided with bayonet lock in a side of bearing pin, the pin joint section of described the first attaching parts be provided with for this bayonet lock be embedded and with the deep-slotted chip breaker of bayonet lock bearing fit, the second attaching parts and the first attaching parts are realized between the two folding Stroke Control by the bearing fit of bayonet lock and deep-slotted chip breaker.
Further, two the first connecting straps that parallel interval arranges about described the first attaching parts is provided with, two the second connecting straps that parallel interval arranges about the second attaching parts is provided with, wherein in first connecting strap on right side is embedded the second gap between two second connecting straps, and in second connecting strap in left side is embedded the first gap between two first connecting straps, described bearing pin pin joint is on above-mentioned two first connecting straps and two second connecting straps, and described deep-slotted chip breaker and bayonet lock are separately positioned on first connecting strap and the second connecting strap of homonymy.
The utility model has the advantages that: the second attaching parts and the first attaching parts are realized between the two folding Stroke Control by the bearing fit of bayonet lock and deep-slotted chip breaker in the utility model, and then realize that better car load is folding.
