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.

The specific embodiment
Present embodiment is that a kind of tool button mounts the bicycle cargo tow tractor of putting, and please referring to the 1st to 4 figure, it comprises:
One traction part 10, traction part 10 is to be provided with one in order to pass the bar portion 11 of bicycle rear axis position, in these bar portion 11 1 ends be provided with one can pull set handle 121 and axially advance and retreat compress 12, compress 12 roughly cylindrical, and axially stretch in outer face and to establish a hanging scroll 13, hanging scroll 13 is circular bar shape and forms enlarged head in free end, bar portion 11 other end spiral shells are provided with one and screw togather 14, screw togather 14 roughly cylindrical, and axially stretch in outer face and to be provided with a hanging scroll 13, hanging scroll 13 is circular bar shape and forms enlarged head in free end, wherein compress 12 and screw togather an inner end surface system of 14 in order to compressing the axle center that clamps cycle stand rear end and trailing wheel relatively, but fix both by this and two hanging scrolls 13 of hook are provided.
One trailer 20, this trailer 20 is foldable trailer, and have a folding support body 21 and and be located at support body 21 rear ends and detouchable trailing wheel 22, support body 21 front ends also articulate two detachable connecting arms 23, corresponding two hanging scrolls 13 of each connecting arm 23 front end also are provided with a button respectively and mount and put 30, each button mounts and puts 30 is to comprise the juxtaposed plate body 31 in two intervals, a fastener 32 and a navigation button 33, wherein
Two at interval juxtaposed plate body 31 be roughly rectangular and each is incorporated into the outer face of connecting arm 23 with the rear side end edge, the juxtaposed plate body 31 in two intervals is concaved with the U-shaped draw-in groove 311 of a corresponding fastener hanging scroll 13 in the front end root edge, and being equipped with an arcuate socket 312 in the opposing end surface of draw-in groove 311 rear sides, the two ends of arcuate socket 312 respectively form the bigger expanded hole of a size 313;
When the utility model uses, system is arranged at traction part 10 shaft core position of bicycle trailing wheel earlier, and trailer 20 mounted with two buttons put 30 draw-in groove 311 and detain two hanging scrolls 13 that are hung on traction part 10 respectively and the towing that can be subjected to traction part 10, and then fastener 32 pivoted forward, its free end is buckled draw-in groove 311 openings, reach purpose by this with bicycle towing trailer 20;
And the location action of fastener 32 is please referring to the 3rd, 5,6 figure, system presses the press button portion 334 of navigation button 33, the major part fastening part 335 that is placed in expanded hole 313 is shifted out and make fastener 32 to pivot, treat to decontrol when major part fastening part 335 moves on to another expanded hole 313 navigation button 33, because the restoring force of elastic parts 333 makes major part fastening part 335 fall into another expanded hole 313, make fastener 32 reach the effect of two sections location by this
