Description
Technical field
The utility model relates to a kind of doll carriage.
Background technology
A kind of doll carriage, comprise the go-cart vehicle frame with expanded position and folding position, the front component that is arranged on described go-cart bottom of frame and wheel assembly, seat, be used for described go-cart vehicle frame is locked in the car load lockout mechanism of expanded position, described go-cart vehicle frame comprises side stand in both sides, be arranged on many cross bars between the described side stand of both sides, the described side stand of every side all comprises front-wheel support, rear wheel support, push rod, perambulator of the prior art, ubiquity go-cart vehicle frame rod member is more, the defective that structure is more loaded down with trivial details.
The utility model content
Technical problem to be solved in the utility model provides a kind of doll carriage, and its go-cart vehicle frame rod member is less, and structure is more succinct.
For solving above technical matters, the utility model is taked following technical scheme:
A kind of doll carriage, comprise go-cart vehicle frame with expanded position and folding position, be arranged on the front component and the wheel assembly of described go-cart bottom of frame, the seat, be used for described go-cart vehicle frame is locked in the car load lockout mechanism of expanded position, described go-cart vehicle frame comprises front-wheel support, rear wheel support, push rod, the front portion of described rear wheel support is rotatably connected to the front portion of boxed rod, the rear portion of described boxed rod rotates with described push rod and is connected, the bottom of described push rod is connected with an end of lower link, the other end of described lower link is connected rotatedly with described rear wheel support, described rear wheel support, described boxed rod, described push rod and described lower link constitute four-bar linkage, length direction along described front-wheel support on the described front-wheel support is provided with sliding part slidably, described rear wheel support is connected rotatedly with described sliding part, and the rearward end of described front-wheel support and described push rod, in two parts of described lower link at least one connects rotatedly.Described car load lockout mechanism only needs any one the run-on point locking in the described four-bar linkage, thereby changes described four-bar linkage into triangle mechanism, even if described go-cart vehicle frame has been locked.The structure that is used to lock the car load lockout mechanism of similar go-cart vehicle frame in the prior art has multiple.As long as and here the lockout mechanism of four-bar linkage locking can both be able to be used.After with the release of described car load lockout mechanism, just described push rod can be pushed over forward, in the effect of four-bar linkage, described go-cart vehicle frame is just folding have been drawn in.And when described go-cart vehicle frame launched locking, only need any one run-on point in the described four-bar linkage of locking, make four-bar linkage mechanism triangular in shape, and this moment, described rear wheel support, described front-wheel support, described push rod and or described lower link between also constitute triangle mechanism, the car load expanded position is just stable.
Described seat removably connects mutually with described go-cart vehicle frame.
Described rear wheel support is provided with fitting under the seat, and described seat is provided with fitting on the seat, under the described seat on fitting and the described seat fitting removably connect mutually.
Described seat is a kind of in babychair pocket, automobile seat bag, the baby sleeping basket.
The place of being rotationally connected of described rear wheel support and described sliding part is positioned at the top that is rotationally connected and locates of the other end of described rear wheel support and described lower link.
Described car load lockout mechanism is arranged between the bottom of rear wheel support and push rod.
One end three's same axis of the rearward end of described front-wheel support, described push rod, described lower link is rotationally connected to preferably.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage: because four-bar linkage and front-wheel support and sliding part complement each other, by the car load lockout mechanism that go-cart vehicle frame locking back whole vehicle stability is better, and go-cart vehicle frame release pusher vehicle carriage just can be folded, thereby go-cart vehicle frame rod member is less, and is simple in structure, productive costs is lower.
