Description

A kind of Novel simple type child's bicycle frame

Technical field

The utility model relates to bicycle rack technical field, particularly relates to a kind of Novel simple type child's bicycle frame.

Background technology

Bicycle has become the indispensable vehicle in people's daily life, bicycle is made up of parts such as vehicle frame, tire, foot-operated, brake, chains, wherein vehicle frame is the skeleton of bicycle, it is the basic structure body forming bicycle, at present, minibike is a more and more welcome colony in bicycle, and the bicycle structure that prior art is produced is complicated, its bicycle rack is combined by various parts, structure design is more loaded down with trivial details, this is little for meeting bicycle quality, and the requirement that bulk strength is high is very unfavorable.

Utility model content

For the present situation of above-mentioned prior art, it is few, lightweight that technical problem to be solved in the utility model is to provide a kind of part, sound construction, the Novel simple type child's bicycle frame that intensity is high.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of Novel simple type child's bicycle frame, comprise head tube, lower pipe, middle pipe and lower fork, described lower pipe and lower fork one-body molded, the front end of described lower pipe is fixedly connected with head tube, the tail end of described lower pipe is fixedly connected with middle pipe, the angle that this lower Guan Yuzhong pipe is formed is 60-70 degree, described lower fork is U-shaped, this lower fork comprises bending section and linear portion, this bending section is connected between linear portion, make structure more firm, described lower fork is provided with crossbeam, this crossbeam is arranged on the intersection of bending section and linear portion, this crossbeam and bending section form sealing ring, described middle pipe is positioned at this sealing ring, improve loading strength.

Further, described crossbeam has circular hole, can gas exchanges be carried out.

Further, described lower fork end is connected with hook.

Further, described lower pipe has for connecting foot-operated perforate.

Compared with prior art, the utility model has the advantage of: the utility model structure is simple, abandoning tradition bicycle is by the combination of the multiple parts such as upper pipe, lower pipe, middle pipe, head tube, upper fork, lower fork and five-way, only carry out vehicle frame combination with less part, alleviate tare, and connect rationally between each part, middle pipe and lower pipe form the angle of 60-70 degree, intensity is high, and load is good, is suitable for child's bicycle.

Accompanying drawing explanation

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

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

Fig. 3 is birds-eye view of the present utility model.

Detailed description of the invention

As Figure 1-3, a kind of Novel simple type child's bicycle frame, comprise head tube 1, lower pipe 2, middle pipe 3 and lower fork 4, described lower pipe 2 is one-body molded with lower fork 4, the front end of described lower pipe 2 is fixedly connected with head tube 1, the tail end of described lower pipe 2 is fixedly connected with middle pipe 3, the angle that this lower pipe 2 and middle pipe 3 are formed is 60-70 degree, described lower fork 4 is U-shaped, this lower fork 4 comprises bending section and linear portion, this bending section is connected between linear portion, make structure more firm, described lower fork 4 is provided with crossbeam 6, this crossbeam 6 is arranged on the intersection of bending section and linear portion, this crossbeam 6 forms sealing ring with bending section, described middle pipe 3 is positioned at this sealing ring, improve loading strength, described crossbeam 6 middle has circular hole, inside and outside gas exchanges can be carried out, because bicycle frame pipe mostly is hollow tube, offer circular hole can prevent vexed tide in pipe and corrosion occurs, described lower fork 4 end is connected with hook 5, described lower pipe 2 has for connecting foot-operated perforate, described middle pipe 3 is hollow cylindrical tube, in this, pipe 3 upper port edge has U-type groove.

The utility model structure is simple, abandoning tradition bicycle is by the combination of the multiple parts such as upper pipe, lower pipe, middle pipe, head tube, upper fork, lower fork and five-way, only carry out vehicle frame combination with less part, alleviate tare, and connect rationally between each part, middle pipe and lower pipe form the angle of 60-70 degree, and intensity is high, load is good, is suitable for child's bicycle.

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.
