Description

Extension bicycle

Technical field

The present invention is the invention about extension bicycle.

Technical background

For bicycle and man, laterally folded mode is very laborious, and X compound rod, two pipes, groove pipe, square tube etc. are flexible Mode material is nonstandard, make difficulty, vehicle is the most beautiful, folding also has some setbacks, and such as Patent No. 200249968.7, it stretches The both sides tube wall of pipe must make two grooves being parallel to pipe axis, and manufacture difficulty is very big, outward appearance is indecency, rigidity is deteriorated.For Electric bicycle, above-mentioned folding mode is more unsuitable.

Summary of the invention: extension bicycle, comprises Herba Plantaginis body, Che Houti, retractor device, retractor device by have guided way post and The telescoping tube of locating dowel, having the trocar sheath of guide slit, Fast detachable unit, bitubular blind nut to constitute, the inner tubal wall of the right-hand member section of telescoping tube has Screw thread, there is guided way post in the direction of the length of the downside tube wall of telescoping tube, and there are locating dowel, locating dowel in the right-hand member place to the left of guided way post Width equal to the height of the width of guided way post and locating dowel higher than the height of guided way post, the internal diameter of outer tube sleeve is slightly larger than stretching The external diameter of the draw, the outer tube wall of the right-hand member section of outer tube sleeve has screw thread, and there is guide slit in the direction of the length of the downside tube wall of outer tube sleeve, leads Be equal to the height of guided way post more than the width of guided way post and the height of guide slit to the width of seam, the left end of telescoping tube welds admittedly In Herba Plantaginis body, the body of telescoping tube is inserted in trocar sheath from right-hand member, and the stage casing of trocar sheath is welded in aftercarriage admittedly, and Fast detachable unit overlaps outside On the outer tube wall of left section of sleeve pipe, bitubular blind nut stretches state swivel nut on the inner tubal wall of the right-hand member section of telescoping tube and trocar sheath at car On the outer tube wall of right-hand member section, at car contracting state swivel nut on the inner tubal wall of the right-hand member section of telescoping tube.

Invention benefit: the bicycle of the present invention uses only by having the telescoping tube of guided way post and locating dowel, having guide slit The retractor device that trocar sheath, Fast detachable unit, bitubular blind nut are constituted just can stretch, and hand operation bicycle is flexible only needs one to number Second, i.e. improve X-type, double telescoping tube type, groove telescoping tube type, the stretching structure of side's telescoping tube type, also overturn traditional laterally folded Structure, also can realize the flexible of electric bicycle.

Accompanying drawing is washed bright

What Fig. 1 showed rail bar formula extension bicycle stretches state, and Fig. 2 shows the contracting state of rail bar formula extension bicycle, and Fig. 3 shows that colonnade formula is stretched Contracting bicycle stretch state, Fig. 4 shows the contracting state of colonnade extension bicycle, and Fig. 5 shows rail bar formula telescoping tube left view, and Fig. 5, Fig. 6, Fig. 7 show Rail bar formula telescoping tube left view, main regarding depending on, the right side, Fig. 8, Fig. 9, Figure 10 show colonnade formula telescoping tube left view, main regard depending on, the right side, Figure 11, Figure 12 Show Fast detachable unit side-looking, main regard, Figure 13, Figure 14 show trocar sheath survey depending on, main regard；Figure 15, Figure 16, Figure 17 show bitubular blind nut side-looking, master Depending on, section view.In Fig. 1 to Fig. 8: Herba Plantaginis body-1, telescoping tube-2, rail bar-21, colonnade-22, locating dowel-23, Fast detachable unit-3, overcoat Pipe-4, guide slit-41, bitubular blind nut-5, Che Houti-6.

Detailed description of the invention

Embodiment one as shown in Figure 1, Figure 2, shown in Fig. 5 to Fig. 7 and Figure 11 to Figure 17: rail bar formula extension bicycle comprises Herba Plantaginis body 1, body 2, retractor device after car, retractor device is by there being the overcoat guiding rail bar 21 and the telescoping tube 2 of locating dowel 23, having guide slit 41 Pipe 4, Fast detachable unit 3, bitubular blind nut 5 are constituted, and the inner tubal wall of the right-hand member section of telescoping tube 2 has screw thread, leading of the direction of downside tube wall length Being rail bar 21 to rail post, there is locating dowel 23 at the right-hand member place to the left of rail bar 21, the width of locating dowel 23 and the most respectively etc..
