Abstract

The utility model discloses a novel bicycle backseat support comprising frame and iron board. The front end of the frame is equipped with a rotation shaft in the middle of which a hole is arranged, the back end of the frame is equipped with a snap-lock, and the bottom of the frame is equipped with support bar. One end of the iron board is provided with a long shaft traversing through the hole of the rotation shaft, and steps and a positioning pole are arranged on the long shaft. The other end of the iron board is provided with block iron to match the snap-lock; thereby the iron board and frame form a nesting matching. One side of the iron board is welded with a pinchcock, and the other side is fixedly equipped with a sponge pad. The practical effect of this utility model is, facilitating the bicycle easily to convert between carrying goods and carrying children. Furthermore, its structure is simple.

Description

Mounting behind a kind of new bicycle

Technical field:

The utility model relates to a kind of rear bicycle frame, especially can belongings and the dual-purpose back mounting that carries children.

Background technology:

At present, known rear bicycle frame is made up of framework and spring clip.During by back mounting belongings, by the fixing article of spring clip auxiliary ropes.Groups of people also use the back mounting to carry children.But children's ride-on is on the framework and spring clip of fine strip shape ferrous materials, and traveling comfort is very poor, causes the children's that take local skin extravasated blood easily.Also have groups of people to use additional special-purpose children to take advantage of chair or additional cushion, but take advantage of structure of chair complexity, volume ratio bigger, and added take advantage of chair or cushion after, bearing article easily just.

The utility model content:

The purpose of this utility model is to overcoming the rear bicycle frame that above-mentioned deficiency provides a kind of manned loading conveniently to change.

The utility model is taked following technique measures: mounting behind a kind of new bicycle, be made up of framework, iron plate, laterally be provided with a S. A. at the framework front end, the S. A. midway location is provided with a through hole, back-end framework is provided with a rim lock, base of frame is equipped with the cross-tie bar, and described iron plate one end is provided with major axis, and major axis passes the through hole on the S. A., major axis is provided with step and dowel hole, the iron plate other end is provided with a grade iron, is used with rim lock, and iron plate cooperates with framework is nested.

Described iron plate simultaneously is welded with spring clip, and another side is fixed with foam-rubber cushion.

Rim lock is made up of dead bolt, spring, draw ring, and dead bolt passes the hole on the described framework, at the dead bolt middle part baffle plate is installed, and spring housing is connected on the dead bolt, and draw ring passes the dead bolt other end and is connected with dead bolt.

The beneficial effects of the utility model are, can be by the operations of convenient and simple conversion, and make bicycle realize belongings and carry conversion between the children, simple in structure.
