Description
Technical Field
[0001] The utility model relates to the field of bicycles, in particular to a three-wheel bicycle with a front bucket. Background Art
[0002] The front-bucket bicycle is a favorite means of transportation for Europeans. Children can be carried in the front bucket, or purchased items can be placed in it. It is green for travel, convenient and practical. There are many domestic bicycle manufacturers producing front-bucket bicycles for export to Europe, including front-bucket two-wheel bicycles and front-bucket three-wheel bicycles. The front bucket also includes an integrally formed type or a four-sided assembled type. Most of the four-sided assembled types use four connecting rods erected at the four corners of the vehicle chassis, and the four connecting rods are respectively connected to four side plates for assembly. In this way, relying only on the four bottom ends of the connecting rods and the four force points on the vehicle base, and the pulling directions of the upper parts of the connecting rods by the four panels are different, it is not strong enough. When an external force acts on the upper part, especially when the connection between the connecting rod and the panel is loose, the bucket is likely to be deformed or even separated, and there is a lack of safety. Content of the Utility Model

By innovatively designing a bucket without connecting rods, the traditional four-sided straight plate is designed into two "arc-angle C"-shaped panels and two straight panels. At the same time, the four connecting rods are omitted. The two ends of the two straight panels are respectively connected and fixed to the two ends of the two "arc-angle C"-shaped panels by a pair of inner and outer clips with bolts to form a bucket main body; and a number of locking buckles are arranged on the arc angles of the two sides, and two bent pipes are inserted into the locking buckles. When lowered, it serves as an armrest, and when raised, it serves as a frame, with dual functions; two seat plates are arranged in the bucket, and children's pedals are arranged on both sides of the bucket to form steps for children to get in and out of the bucket conveniently; it reflects the superiority of scientific, simple and flexible design.
