Description

Doll carriage

Technical field

The utility model relates to a kind of doll carriage.

Background technology

Doll carriage of the prior art, comprise the go-cart vehicle frame, be separately positioned on the front-wheel and the trailing wheel of described go-cart vehicle frame below, described go-cart vehicle frame comprise the push-down handle bar that is positioned at both sides, both ends respectively with the upper end of described both sides push-down handle bar by the turning cylinder bonded assembly push-up handle bar that rotates, when folding, described push-up handle bar also can fold by described relatively push-down handle bar, thereby make the go-cart vehicle frame be foldable to littler volume, be convenient to transportation.But owing to be rotationally connected between push-down handle bar and the push-up handle bar, trailing cable can't pass this place that is rotationally connected, thereby the tripper of this vehicle frame can only be arranged on the push-down handle bar of both sides, it is the bottom that the tapered end of tripper is arranged at both sides push-down handle bar respectively, the unlocking operation spare of tripper is separately positioned on the top of both sides push-down handle bar, be provided with trailing cable between the unlocking operation spare of each side and the tapered end, when with the go-cart vehicle frame folding that launches, need both hands to operate the unlocking operation spare of both sides simultaneously, thus could be with the release of go-cart vehicle frame to the go-cart vehicle frame folding.

Summary of the invention

The utility model purpose provides a kind of doll carriage, and it can be connected with trailing cable between described tapered end and the described unlocking operation spare after the bottom that unlocking operation spare and both sides push-down handle bar are set on the push-up handle bar is provided with tapered end.

For achieving the above object, the technical solution adopted in the utility model is: a kind of doll carriage, comprise the go-cart vehicle frame, be arranged on the front-wheel of the following front portion of described go-cart vehicle frame, be arranged on the trailing wheel at the following rear portion of described go-cart vehicle frame, described go-cart vehicle frame comprises the push-down handle bar that is positioned at both sides at least, the upper end of bottom and the described push-down handle bar bonded assembly push-up handle bar that rotates, be provided with trailing cable in the inner chamber of described push-up handle bar, the outside around the axial line that is rotationally connected of described push-up handle bar and described push-down handle bar has flexible fixed length noose passage, be provided with flexible fixed length noose in the described flexible fixed length noose passage, described flexible fixed length noose is enclosed within on the described trailing cable, and described trailing cable stretches in the inner chamber of described push-down handle bar.

Because technique scheme utilization, the utility model compared with prior art has following advantage: when unlocking operation spare being set on the push-up handle bar and tapered end being set respectively on the bottom of both sides push-down handle bar, tapered end is provided with trailing cable, described trailing cable extends upward along the inner chamber of push-down handle bar, because described trailing cable passes the described second trailing cable passage, the inner chamber of flexible fixed length noose, the described first trailing cable passage enters the inner chamber of described push-up handle bar again, and the trailing cable of therefore last both sides just can be connected with the both sides of unlocking operation spare respectively.
