Abstract

The utility model relates to a bicycle goods trailer with a buckle hanging device. Hanging shafts arranged on the front end of the trailer corresponding to both sides of the back end of a bicycle are respectively connected with a buckle hanging device. One end of each buckle hanging device is provided with a U-shaped clamping groove for buckle hanging on a corresponding hanging shaft, and is pivoted with a two-stage positioning fastener. The trailer can be dragged by the method that the fastener is hooked on the opening of the clamping groove and the hanging shaft is positioned in the clamping groove. The utility model achieves the goal of dragging the trailer by the two-stage positioning fastener positioning the hanging shaft in the clamping groove. Because the fastener is buckled in a rotary mode and has a positioning design, when subjected to sudden external force, the fastener can not shift position, so better positioning and buckling effect is achieved.
