Description

A kind of novel simple assembling formula bicycle rack

Technical field

The utility model relates to bicycle rack technical field, particularly relates to a kind of novel simple assembling formula bicycle rack.

Background technology

The bicycle structure that prior art is produced is complicated, its bicycle frame structure is combined by various parts, and structure design is also reasonable not, this is little for meeting child's bicycle quality, and the requirement that bulk strength is high is very unfavorable, and existing bicycle rack is not only heavy, and Joint strenght is not high yet, and vehicle frame is overall to be connected with Type of Welding, cannot splice and dismantle, be not easy to use and transport.

Utility model content

For the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of structure simple, the high and easy-to-mount novel simple assembling formula bicycle rack of Joint strenght.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of novel simple assembling formula bicycle rack, comprise head tube, middle pipe, lower pipe and lower fork, described middle pipe is arranged on the junction of lower pipe and lower fork, described head tube is arranged on the front end of lower pipe, and described lower fork is provided with strength beam, and described middle pipe lower end is plugged with pedal pipe, this pedal pipe comprises transverse tube and vertical tube, this transverse tube and vertical tube orthogonal, be provided with pilot bar in this vertical tube, this pilot bar is parallel with transverse tube.

Further, described middle pipe lower end has the guide groove that can slip pilot bar, and this guide groove is symmetrically distributed in middle pipe both sides, and one end of this guide groove extends to middle tube edges, is convenient to grafting pedal pipe, avoids installation direction deviation.

Further, described middle pipe has mounting hole, described vertical tube has the circular hole corresponding with middle pipe mounting hole, this mounting hole and circular hole are located by connecting by screw, connect more firm.

Further, described middle pipe and head tube parallel to each other, there is resistance to compression effect.

Further, described lower pipe is curved, has resistance to compression effect.

Further, described transverse tube is provided with the axis hole can installing pedal, can installation foot pedal.

Compared with prior art, the utility model has the advantage of: the utility model structure is simple, only adopt lower pipe, lower fork, head tube and middle pipe four textural associations, middle pipe is arranged on the junction of lower pipe and lower fork, lower fork establishes strength beam, thus improve the integrated connection intensity of vehicle frame, in addition, middle pipe and pedal pipe adopt the mode of grafting, be convenient in the dismounting used and in transportation, the utility model is reasonable in design, meets mechanics principle, is applicable to large-scale promotion.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is cutaway view of the present utility model;

Fig. 3 is front view of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.

As Figure 1-3, a kind of novel simple assembling formula bicycle rack, comprise head tube 1, middle pipe 3, lower pipe 2 and lower fork 4, described middle pipe 3 is arranged on the junction of lower pipe 2 and lower fork 4, described head tube 1 is arranged on the front end of lower pipe 2, described lower fork 4 is provided with strength beam 6, described middle pipe 3 lower end is plugged with pedal pipe 5, this pedal pipe 5 comprises transverse tube and vertical tube, this transverse tube and vertical tube orthogonal, pilot bar 51 is provided with in this vertical tube, this pilot bar 51 is parallel with transverse tube, described middle pipe 3 lower end has the guide groove 31 that can slip pilot bar, this guide groove 31 is symmetrically distributed in middle pipe 3 both sides, one end of this guide groove 31 extends to middle pipe 3 edge, be convenient to grafting pedal pipe 5, avoid installation direction deviation, described middle pipe 3 has mounting hole 32, this mounting hole 32 is two, described vertical tube has the circular hole corresponding with middle pipe mounting hole 32, this mounting hole 32 is located by connecting by screw with circular hole, installation site and the pilot bar 51 of this screw are orthogonal, connect more firm, described middle pipe 3 is parallel to each other with head tube 1, described lower pipe 2 is curved, there is resistance to compression effect, described transverse tube is provided with the axis hole can installing pedal, can installation foot pedal.

During assembling, pilot bar 51 on pedal pipe 5 is slipped into the guide groove 31 on middle pipe 3, offset to pilot bar 51 and guide groove 31 in pipe 3 during pedal pipe 5 inserts, now, mounting hole 32 on middle pipe 3 overlaps with the circular hole on vertical tube, screw is tightened through mounting hole 32 and circular hole, just pedal pipe 5 is fixed on middle pipe 3; During dismounting, screw is unscrewed, pedal pipe 5 is extracted out.

The utility model structure is simple, the bicycle rack of abandoning tradition is by the array mode of the various parts such as upper pipe, lower pipe, head tube, upper fork, lower fork and Five-way tube, only adopt lower pipe, lower fork, head tube and middle pipe four textural associations, middle pipe is arranged on the junction of lower pipe and lower fork, lower fork establishes strength beam, thus improves the integrated connection intensity of vehicle frame, in addition, middle pipe and pedal pipe adopt the mode of grafting, are convenient in the dismounting used and in transportation.

Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
