Description
Technical field
The utility model relates to a kind of tandem bicycle frame, belongs to the bicycle rack technical field.
Background technology
Existing tandem bicycle frame only is the top tube and down tube lengthening with the ordinary bicycle frame, what seat pipe of increase formed on last pipe then.Itself Joint strenght of existing bicycle rack is not fine just, and Jia Chang words just make that Joint strenght is poorer again.
The utility model content
The purpose of this utility model is for solving the problems of the technologies described above, a kind of tandem bicycle frame being provided.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
The tandem bicycle frame, comprise head pipe, go up pipe, middle pipe, down pipe, go up fork, lower fork and five-way, describedly also be fixed with a pipe in the middle part of going up pipe; Following pipe middle part also is provided with a four-way, and a wherein end of last pipe is fixed on the five-way jointly with a wherein end of following pipe, and the top tube and down tube one connects; Also be provided with a stirrup between middle pipe and the last pipe.
Existing tandem bicycle frame is carried out force analysis as can be known, because lengthening, make the top tube and down tube easy fracture that becomes.And in the utility model technique scheme, the point of connection of last Guan Yuzhong pipe is moved down, between middle pipe and last pipe, also be provided with a stirrup; And the top tube and down tube one is connected; These structure Design make Joint strenght of the present utility model be improved.
In the technique scheme, stirrup be arranged so that structure of the present utility model is more stable; Four-way and five-way then are used to be provided with pedal assembly; The top of middle pipe is used to be provided with bench, and a seat Guan Ze is used to be provided with another bench.
Preferred as technique scheme, the described length that goes up pipe is 1.0～1.5m, last pipe is 135～150 ° with the angle of lower fork formation.
In sum, the utlity model has following beneficial effect:
The utlity model has the high advantage of Joint strenght.
