Abstract
The utility model relates to a baby trolley comprising a trolley frame, front wheels and rear wheels, wherein the trolley frame at least comprises a push handle rod and a rod component of which the end part is rotationally connected with the push handle rod; a locking mechanism is arranged between the push handle rod and the rod component; the locking mechanism comprises a traction rope, a locking pin connected with the traction rope, and an insertion hole arranged on the rod component; the locking pin is in sliding arrangement in the cavity of the push handle rod; an inclined plane is arranged at the lower part of the locking pin. When the traction rope is pulled to a limit position, a part with the inclined plane of the locking pin is still inserted in the insertion hole; then, the push handle rod corresponding to the rod component is rotated and the inclined plane is butted at the opening of the upper end on the insertion hole. When the traction rope is pulled to a limit position, the locking pin is still inserted in the insertion hole and the trolley frame can not be folded; if the trolley frame is folded, the push handle rod is rotated again; simultaneously, the locking pin overcomes the elastic force of an elastic component and is separated from the insertion hole under the action of the inclined plane; then, the trolley frame is folded.
Description
Technical field
The utility model relates to a kind of improved doll carriage.
Background technology
In the prior art, comprise the go-cart vehicle frame, be arranged at the front-wheel of the lower front of described go-cart vehicle frame, be arranged at the trailing wheel of the lower rear of described go-cart vehicle frame, described go-cart vehicle frame comprises pulling handle rod at least, rod member, the end of described rod member rotates with described pulling handle rod and is connected, be provided with lockout mechanism between described pulling handle rod and the described rod member, described lockout mechanism comprises the trailing cable in the inner chamber that is arranged on described pulling handle rod, the lock pin that is connected with described trailing cable, be opened in the jack on the described rod member, the part of described lock pin is slidingly arranged in the inner chamber of described pulling handle rod, be provided with elastic component between described lock pin and the described pulling handle rod, when lockout mechanism is in the lock state, another part of described lock pin is inserted in the described jack, when described lockout mechanism was in released state, described lock pin broke away from described jack.At present when lockout mechanism is in the lock state, only need the described trailing cable of pulling to end position, described lock pin just can break away from described jack fully, the go-cart vehicle frame is just collapsible subsequently gets off, this lockout mechanism can not avoid mistake to spur the auto-folder of the go-cart vehicle frame that described trailing cable causes, has unsafe hidden danger.
Summary of the invention
The utility model purpose provides a kind of doll carriage, when pulling trailing cable during to end position, still needs second kind of action and could make the complete release of lockout mechanism, makes described go-cart vehicle frame folding.
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 at the front-wheel of the lower front of described go-cart vehicle frame, be arranged at the trailing wheel of the lower rear of described go-cart vehicle frame, described go-cart vehicle frame comprises pulling handle rod at least, rod member, the end of described rod member rotates with described pulling handle rod and is connected, be provided with lockout mechanism between described pulling handle rod and the described rod member, described lockout mechanism comprises the trailing cable in the inner chamber that is arranged on described pulling handle rod, the lock pin that is connected with described trailing cable, be opened in the jack on the described rod member, the part of described lock pin is slidingly arranged in the inner chamber of described pulling handle rod, be provided with elastic component between described lock pin and the described pulling handle rod, when lockout mechanism is in the lock state, another part of described lock pin is inserted in the described jack, when described lockout mechanism is in released state, described lock pin breaks away from described jack, the bottom of described lock pin has the inclined-plane, described lockout mechanism from lock-out state to the released state switching process, and when spurring described trailing cable to end position, the part with inclined-plane of described lock pin still is inserted in the described jack, when making that pulling handle rod rotates with respect to rod member subsequently, described inclined-plane is against the upper end oral area of described jack.
Because technique scheme utilization, the utility model compared with prior art has following advantage: since described lockout mechanism from lock-out state to the released state switching process, when spurring described trailing cable to end position, the part with inclined-plane of described lock pin still is inserted in the described jack, thereby lockout mechanism still is in the lock state, the go-cart vehicle frame still can not fold, if want the Folding trolley vehicle frame, need rotate described pulling handle rod again, described lock pin overcomes the elastic force of elastic component, and break away from described jack under the effect on inclined-plane, the go-cart vehicle frame could fold.
