Car wire casing

This creation is about a wire bushing for a car.

In general, the bicycle braking system or the shifting system is connected to the handlebar by a brake line or shifting line for user control, and the user's power can be transmitted to the braking system or the shifting system via the brake line or the shifting line. Perform actions such as clamping.

Therefore, bicycle wires such as brake lines or shifting lines are indispensable, and the bicycle wires must be connected to the operating area (such as the brake mechanism) from the handlebars, and must extend a distance through the frame during the journey, and, in order to cooperate The frame and the bicycle wire often have to be bent moderately. However, it is difficult to accurately transmit the force when the bent bicycle wire is pulled, and may even be stuck and malfunction, which becomes a safety worry for riding.

In this regard, the industry has developed a sleeve for a bicycle wire for the bicycle wire to be threaded therein and allowing the bicycle wire to move axially therein, whereby the movement path of the bicycle wire can be secured and positioned. It can not only avoid the situation that the bicycle wire is not pulled or stuck, but also can be used as a protection to avoid damage to the bicycle wire caused by external force impact, wear, or rain or sun exposure.

Generally, the sleeve comprises an inner layer formed by winding a metal wire and a coating layer wrapped around the wire, wherein the coating is provided for better weather resistance and structure. Polypropylene is often used as the material. However, the metal wire structure is rigid but not bendable, and excessive bending may cause breakage, which is still insufficient as a casing that must be bent. I know it.

The main purpose of this creation is to provide a wire bushing for a vehicle that provides better flexural flexibility and durability.

In order to achieve the above object, the present invention provides a wire bushing for a vehicle comprising an inner tube, a fiber layer and an outer layer.

The inner tube is formed by a bicycle wire, and the fiber layer is formed by a plurality of strands arranged around the inner tube and wound around the inner tube, each of the strands being made of glass fiber, the outer layer of the fiber layer The surface is formed with a plurality of recesses between the strands, the outer cover is made of nylon, the outer cover is coated on the outer surface of the fiber layer and a part of the outer cover fills the concave Seam.

Therefore, the wire bushing for the vehicle provided by the present invention has a better bending elasticity due to the use of the glass fiber strand, and the nylon material is used as the outer layer to have better bonding ability with the glass fiber, so that the whole The structure is more stable and further enhances durability by the high weatherability of nylon, high impact resistance and high friction resistance.

Figure 4 is a schematic diagram of the use of the present creation.

The following is a description of possible implementations of the present invention by way of example only, and is not intended to limit the scope of the creation of the present invention.

Referring to FIG. 1 to FIG. 3 , the present invention provides a wire bushing 10 for a vehicle, comprising an inner tube 11 , a fiber layer 12 and an outer cover 13 .

The inner tube 11 has a cavity for a bicycle wire 20 to be inserted therein, and the material thereof is preferably polyethylene, Teflon or plastic steel; the fiber layer 12 is arranged around the inner tube 11 and wound by a plurality of strands 121. The inner tube 11 is formed, and each of the strands 121 is made of glass fiber. The outer surface of the fiber layer 12 is formed with a plurality of recesses between the strands 121. More specifically, in general, Each of the strands 121 has a cylindrical strip shape. Therefore, even if the strands 121 are closely wound with each other, a plurality of groove-like recesses are formed on the outer surface; the outer covering layer 13 is coated on the fiber. The outer surface of the layer 12 and a portion of the outer cover 13 fill the recesses, and the outer cover 13 is made of nylon. Preferably, the outer cover 13 is coated with a hot melt nylon material. The outer surface of the fibrous layer 12 is cooled and formed, and the hot melted nylon material is fluid and can penetrate into the recesses, thereby filling the recesses and simultaneously bonding the fibrous layers to each other.

In actual use, please refer to FIG. 1 to FIG. 3 and refer to FIG. 4 together. The vehicle wire bushing 10 provided by the present invention is installed outside a bicycle wire 20, such as a brake wire or a shift wire as a power transmission wire. Since the bicycle wire 20 is to be connected to a braking mechanism or the like, the wire bushing 10 for the vehicle must also extend along with the bicycle wire 20, which inevitably needs to be moderately curved to match the path of the bicycle wire extension, and the glass fiber is used in the creation. As the fiber layer 12, the bendability of the wire bushing for the vehicle is better than that when the wire is wound, and the outer cover 13 is made of a nylon material to improve the adhesion to the fiber layer 12. Therefore, the vehicle is used. When the wire sleeve 10 is bent, the outer cover 13 and the fiber layer 12 are not easily peeled off, thereby maintaining the structural integrity.

With the above structure, the wire bushing for the vehicle provided by the present invention improves the bending ability and the recovery ability by the fiber layer of the glass fiber, and the outer layer of the nylon material improves the bonding ability with the glass fiber, so that the outer cover layer can Tightly bonded to the fiber layer to avoid peeling, and the nylon outer cover has good scratch resistance, weather resistance and impact resistance, which can provide excellent protection for the inner fiber layer, inner tube and bicycle wire. Increased durability of use, glass fiber replaces metal to help reduce weight and improve progress.
