Description

Simple and easy bicycle rack

Technical field

The utility model relates to a kind of bicycle rack, relates in particular to a kind of simple and easy bicycle rack, belongs to the bicycle rack technical field.

Background technology

The bicycle structure complexity that prior art is produced, its body frame structure for automotive is combined by multiple part, and structure design is also reasonable inadequately; This is very unfavorable for satisfying the new demand that the bicycle quality is little, bulk strength is high.Existing bicycle not only heaviness but also Joint strenght is not high yet.

The utility model content

The purpose of this utility model is for solving the problems of the technologies described above, a kind of simple and easy bicycle rack is provided, and it improves the problems referred to above from the structure angle.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:

Simple and easy bicycle rack comprises head pipe, middle pipe, following pipe and lower fork, and described middle pipe is arranged on down on the pipe; Following Guan Yiduan connector pipe, the following pipe other end is captiveed joint with lower fork; Also offer on the described pipe down and be used to connect foot-operated perforate.

In the utility model technique scheme, abandoned traditional bicycle rack was managed, gone up multiple parts such as fork, lower fork and five-way pipe by last pipe, following pipe, head array configuration; Adopt and only use the array configuration of pipe, lower fork and head pipe, these four necessary structures of middle pipe down.Although it is simple in structure, since reasonable in design, consider can embody preceence all the better from loading angle.Therefore, the utility model is simple in structure, the Joint strenght height.

Preferred as technique scheme, described pipe down is " S " type.

In sum, the utlity model has following beneficial effect:

The utility model is simple in structure, connects between each part rationally, makes to the utlity model has lightly, and the advantage that intensity is high is suitable for dolly very much.
