Description

Bicycle wire

This creation is related to wires, especially a kind of wire for bicycles.

In general, the braking device and the gear shifting device of a bicycle are controlled by a wire which includes an inner wire and a set of pipes arranged on the outer periphery of the inner wire. The catheter is used for the inner wire to pass through, so that the inner wire can slide in the inner space of the catheter, and provides moisture-proof and impact-resistant effects to protect the inner wire.

The conventional catheter includes an inner tube, a metal layer arranged on the outer periphery of the inner tube, and at least one glue layer arranged on the outer periphery of the metal layer, and the at least one glue layer is used to fix the metal layer. However, when the catheter is bent under a force, the wire of the metal layer will also bend and radially oppose the at least one adhesive layer, which will cause the at least one adhesive layer to have excessive local pressure and be easily damaged; in addition, the conventional one The appearance of at least one adhesive layer is monotonous, the resulting visual effect is not good, and there are shortcomings that need to be improved urgently.

Therefore, it is necessary to provide a novel and advanced bicycle wire to solve the above-mentioned problems.

The main purpose of this creation is to provide a bicycle wire that is not easily damaged and has good bonding strength.

In order to achieve the above objective, the present invention provides a bicycle wire, including: an inner tube; a metal layer, including at least one metal wire disposed on the outer circumference of the inner tube; a braided layer, ringed around the metal layer, including a plurality of Interlaced braided threads; and an outer layer, which is looped outside the braided layer, and the plural threads are partially embedded in the outer layer radially.

The following examples are only used to illustrate the possible implementation of this creation, but they are not intended to limit the scope of the creation to be protected, and we will explain it first.

Please refer to FIGS. 1 to 6, which show a preferred embodiment of the present invention. The bicycle wire 1 of the present invention includes an inner tube 10, a metal layer 20, a braided layer 30 and an outer layer 40.

Therefore, when the at least one metal wire 21 is bent under a force, the braided layer 30 has better toughness and can effectively disperse the force without being damaged, and has a better bonding strength than a general adhesive layer.

Preferably, the reflectance of the plurality of threads 31 in the visible light wavelength range is not less than 30%, so that the plurality of threads 31 can provide a reflection effect, be beautiful, and can increase driving safety. The inner tube 10 defines an axial direction, the braided layer 30 includes a plurality of strands 32, each of the strands 32 includes at least one thread 31, and the exposed portion of the plurality of strands 32 includes a plurality of staggered arc protrusions 321 , When viewed in a direction oblique to the axial direction, each of the arc protrusions 321 partly forms a bright band 322 and partly forms a dark band 323, as shown in Figures 1 and 4, to produce a special vision of light and dark Effect. In this embodiment, each of the strands 32 includes a plurality of the threads 31 arranged side by side along the outer circumference of the metal layer 20, and the braided layer 30 is knitted by the plurality of strands 32 in a horse-drawn manner, so that the outer circumference of the braided layer 30 A regular uneven surface is formed, and the weaving density is high, which can effectively disperse the thrust force when the at least one metal wire 21 is bent and avoid directly opposing the outer layer 40; when viewed in a direction oblique to the axial direction, the plural The bright bands 322 and the dark bands 323 of the arc convex portion 321 are staggered circumferentially and have special visual effects (such as attachments 1 and 2); the plurality of threads 31 are glitter threads, and the diameter of each thread 31 is between Between 0.03 mm and 0.1 mm (0.05 mm in this embodiment), the reflectivity is high and the line diameter is too large to avoid affecting the reflection effect, and the visual effect is good, conspicuous and eye-catching, which effectively improves driving safety. Of course, the plurality of threads can also be made of other materials.

Preferably, the light transmittance of the outer layer 40 is greater than 50% to avoid shielding the reflected light of the braided layer 30; the outer layer 40 is made of polypropylene (PP), and the average thickness of the outer layer 40 is not less than that of the metal layer 20 The average thickness can provide a smooth surface with good flexibility and toughness without being easily damaged; the average thickness of the outer layer 40 is greater than the average thickness of the braided layer 30, and the braided layer 30 can be fully and completely covered. In detail, the inner peripheral surface of the outer layer 40 includes a plurality of first arc recesses 41 and a plurality of second arc recesses 42. Each of the first arc recesses 41 and each of the second arc recesses 42 is inclined in a different direction with respect to the axial direction. Extending in the direction, each of the threads 31 is partially accommodated in at least one of the plurality of first arc recesses 41 and the plurality of second arc recesses 42 so as to stabilize the connection and not easily misalign with each other. The plurality of first arc recesses 41 are adjacent to each other and arranged along the axial direction; the second arc recesses 42 are adjacent to each other and arranged along the axial direction; each of the first arc recesses 41 and each of the second arc recesses 42 includes a plurality of intervals, respectively The ridges 43 are arranged, and each of the ridges 43 is embedded between the two threads 31, so as to be connected to the plurality of arc protrusions 321 correspondingly to reduce the gap between the braided layer 30 and the outer layer 40, thereby reducing the amount of light Refraction or scattering, good visual effect. In other embodiments, the material of the outer layer can also be made of other resin materials, such as polyethylene, composite resin, etc.

The outer diameter of the wire 1 is 4 mm to 4.5 mm; the inner tube 10 is made of polyethylene (PE), and the diameter of the inner tube 10 can be configured to be 1.5 mm to 2.0 mm according to requirements, so as to be suitable for different Within the wire diameter size. The metal layer 20 includes a plurality of metal wires 21, and a zinc-containing material is provided on the outer peripheral surface of each metal wire 21 to prevent corrosion; for example, when the wire diameter of each metal wire is 0.5 mm, the plurality of metal wires The number of wires can be 18; when the wire diameter of each metal wire is 0.45 mm, the number of the plurality of metal wires can be 16, which can be configured to match the size of the inner tube 10 and the requirements of use. In other embodiments, the metal layer may also be composed of the metal wire spirally wound on the outer peripheral surface of the inner tube.
