Description

Head pipe section bar for bicycle

Technical Field

The utility model relates to a bicycle technical field especially relates to a head pipe section bar for bicycle.

Background

Bicycles, also known as bicycles or bicycles, are typically two-wheeled small land vehicles. After a person rides the vehicle, the person steps on the pedal as power, and the vehicle is a green and environment-friendly vehicle.

The existing bicycle is mainly characterized in that a brake wire of the existing bicycle is an exposed wire routing mode, an electric wire of the existing bicycle is an exposed wire routing mode generally for a certain power-assisted bicycle with a power-assisted function, the exposed wire routing mode is used for the brake wire, the electric wire and other wires, one wire is easy to age, the service life of the wire is short, an electrical fault can be generated, and the appearance attractiveness of the bicycle is influenced by the other wire. The wiring mode of the existing bicycle is mainly limited at the head pipe part of the bicycle, and because the front fork, the handle and other parts of the bicycle are rotatably connected relative to the head pipe, wires are difficult to hide at a rotating joint.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the not enough of existence among the prior art, the utility model provides a can realize that the wire rod hides at the head pipe position of bicycle and walks bicycle head pipe section bar of line.

The technical scheme is as follows: in order to achieve the purpose, the head tube section for the bicycle comprises an inner tube and an outer tube which are concentrically arranged;

the inner pipe and the outer pipe are connected through a plurality of connecting ribs; the connecting ribs extend along the axial direction of the inner pipe;

and the side wall of the outer pipe is provided with a wire outlet hole penetrating through the wall thickness of the outer pipe.

Furthermore, the wire outlet hole penetrates the head pipe profile for the bicycle integrally along the radial direction of the outer pipe; and a plurality of wiring cavities formed by the inner pipe and the outer pipe and separated by the connecting ribs are communicated with the wire outlet holes.

Furthermore, the outer contour of the outlet hole is circular, and the diameter of the outer contour is larger than that of the inner pipe.

Further, one end of the inner tube protrudes outward compared to the outer tube.

Furthermore, the other end of the inner pipe is retracted inwards compared with the outer pipe, and a limiting groove is formed on the outer pipe corresponding to the other end.

Has the advantages that: the utility model discloses a head pipe section bar for bicycle is through setting up inner tube and outer tube to adopt a plurality of splice bar joint inner tubes and outer tube to make annular space between the two separate for a plurality of line chambeies of walking by the splice bar, the various wire rods of bicycle can walk the line and wear out other positions that get into frame or bicycle by wire hole or tip through walking the line chamber, realize hiding the line of walking, and reducible wire rod exposes, improves the wire rod life-span, and promotes the pleasing to the eye degree of bicycle.

FIG. 1 is a first perspective view of a bicycle head tube profile;

FIG. 2 is a second perspective view of a bicycle head tube profile;

fig. 3 is a structural view of a head portion of a bicycle using the head pipe section of the present invention.

The names of the parts indicated by the reference numerals in the drawings are as follows:

1-bicycle head tube section bar; 11-an inner tube; 12-an outer tube; 13-connecting ribs; 14-outlet hole; 15-routing cavity; 16-a limiting groove; 2-a packing piece; 3-a front fork; 4-frame down tube.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The bicycle head tube section bar 1 shown in the attached figure 1 comprises an inner tube 11 and an outer tube 12 which are concentrically arranged; the inner pipe 11 is connected with the outer pipe 12 through a plurality of connecting ribs 13; in this embodiment, the number of the connecting ribs 13 is 4, the connecting ribs 13 extend along the axial direction of the inner tube 11, and all the connecting ribs 13 partition the annular cavity between the inner tube 11 and the outer tube 12 into four fan-shaped routing cavities 15; the side wall of the outer tube 12 is provided with an outlet hole 14 penetrating the wall thickness thereof.

Therefore, by adopting the head pipe section, various wires of the bicycle can pass through the wiring cavity 15 and penetrate out of the end part of the head pipe section or the wire outlet hole 14, the wire outlet hole 14 is connected with the frame pipe, and the wires penetrating out of the wire outlet hole 14 can penetrate into the frame pipe, so that the wires can pass through the head pipe section without being exposed.

Preferably, the outlet hole 14 penetrates the bicycle head tube profile entirely in the radial direction of the outer tube 12; a plurality of routing cavities 15 partitioned by the connecting ribs 13 between the inner pipe 11 and the outer pipe 12 are all communicated with the wire outlet 14. Specifically, the outer contour of the outlet hole 14 is circular, and the diameter of the outer contour is larger than that of the inner tube 11. Therefore, all the wires penetrating through the wire routing cavity 15 can be led out from the wire outlet hole 14, and the wire routing efficiency in the bicycle assembling process can be improved. In addition, all the wiring cavities 15 are communicated with the wire outlet holes 14 in the mode, the processing cost is low, and the wiring can be realized by drilling only one large hole.

One end of the inner tube 11 protrudes outward compared to the outer tube 12; as shown in fig. 2, the other end of the inner tube 11 is retracted inward compared to the outer tube 12, and a stopper groove 16 is formed on the outer tube corresponding to the end.

As shown in the attached drawing 3, the head part of the bicycle using the head tube section bar of the present invention has the following advantages that the upper end of the head tube section bar is provided with the packing part 2, the rotating shaft of the front fork 3 of the bicycle is connected with the inner hole of the inner tube 11 in a rotating way, the front fork 3 is provided with the stop dog, the stop dog is arranged in the limit groove 16, and the two sides of the limit groove 16 can limit the rotating position of the stop dog, so as to limit the rotating angle of the front fork 3.

The side wall of the head pipe section is fixed on the frame lower pipe 4, and the outlet hole 14 of the head pipe section is communicated with the inside of the frame lower pipe 4.

The utility model discloses a head pipe section bar for bicycle is through setting up inner tube and outer tube to adopt a plurality of splice bar joint inner tubes and outer tube to make annular space between the two separate for a plurality of line chambeies of walking by the splice bar, the various wire rods of bicycle can walk the line and wear out other positions that get into frame or bicycle by wire hole or tip through walking the line chamber, realize hiding the line of walking, and reducible wire rod exposes, improves the wire rod life-span, and promotes the pleasing to the eye degree of bicycle.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
