A baby trailer with convenient storage is provided, wherein the baby trailer comprises a trailer frame and a storage structure, the trailer frame comprises a front side frame, a rear side frame, a front chassis frame and a rear chassis frame, the front chassis frame is hinged with the front side frame, the rear chassis frame is hinged with the rear side frame, and the storage structure is hinged with the front side frame and the rear side frame, so that the front side frame and the rear side frame are capable of folded towards the middle.
According to the baby trailer with convenient storage, the storage structure comprises a left storage frame, a right storage frame and a connecting rod, one end of the connecting rod is connected with the left storage frame and the other end of the connecting rod is connected with the right storage frame, and the free ends of the front chassis frame and the rear chassis frame are movably placed on the connecting rod.
According to the baby trailer with convenient storage, the left storage frame and the right storage frame both comprise two horizontal connecting rods, two oblique first connecting rods, two oblique second connecting rods, two first hinge parts and two second hinge parts; the first hinge part is provided on the horizontal connecting rods, one end of the two horizontal connecting rods is hinged to the front side frame and the rear side frame, respectively, and the other end thereof is hinged through the second hinge parts.
According to the baby trailer with convenient storage, the first hinge part is provided with a sleeve and a limiting groove, the limiting groove is provided with a first hinge hole, the horizontal connecting rod passes through the sleeve, one end of the two oblique first connecting rods is embedded into and hinged to the limiting groove, respectively, and the other end thereof is hinged through the second hinge parts.
According to the baby trailer with convenient storage, one end of the oblique second connecting rod is hinged with the first connecting rod, and the other end thereof is hinged with the front side frame or the rear side frame.
According to the baby trailer with convenient storage, the second hinge part comprises two annular rotating parts and two cannula parts provided at one side of the rotating parts, the two rotating parts are rotatably connected by screws, and the cannula parts are inserted into and connected with the horizontal connecting rod/the oblique first connecting rod.
According to the baby trailer with convenient storage, both ends of the connecting rod are connected to the second hinge part hinged with the oblique first connecting rod, respectively.
According to the baby trailer with convenient storage, the baby trailer further comprises a dragging handle and/or a push-pull rod, wherein the dragging handle is provided on the front side frame/rear side frame, which is configured to drag the baby trailer; the push-pull rod is provided on the rear side frame/front side frame, which is configured to push and pull the baby trailer.
According to the baby trailer with convenient storage, the baby trailer is provided with four universal wheels, at least one of which is provided with a braking device.
To sum up, the present utility model uses such a structure, so that the front chassis frame is hinged with the front side frame, the rear chassis frame is hinged with the rear side frame, the storage structure is hinged with the front side frame and the rear side frame, and the front side frame and the rear side frame can be folded towards the middle. Therefore, compared with the prior art, the present utility model has the beneficial effects of convenient opening or storage when in use and small occupied space after storage, and is suitable for wide popularization and application.
