Line pipe structure for bicycle

Abstract

The invention relates to a line pipe structure for a bicycle, which comprises a line pipe body, wherein a line slot through which a braking line or a variable speed line of the bicycle passes is formed on the central part of the line pipe body; the line pipe body consists of rigid metal layers and flexible metal layers; the rigid metal layers and the flexible metal layers are in the overlapping state and wind out of the line pipe body layer by layer; the line pipe body achieves the effects of bending and sizing by the flexible metal layers, and the rigidity of the outer surface of the line pipe body can be improved by the rigid metal layers to prevent the line pipe body from being deformed under the action of the compression of external force. In addition, the rigid metal layers and the flexible metal layers are in the overlapping and layer-by-layer winding state, so that the flexible metal layers are overlapped among the rigid metal layers; and the integral line pipe body achieves the effect of high extensibility by the characteristic of the elasticity of the flexible metal layers. By the line pipe structure, multivariant flexible adjustment and the arrangement of elastic extensity are provided.

Description

technical field [0001] The invention relates to a bicycle cable structure. Background technique [0002] The speed change wire and the brake wire are very important to the speed control of the bicycle, and they are the key to mastering the speed and safety of the bicycle; The bundle tube is covered by the tube and assembled in the transmission and brake lever. [0003] Generally, when the bicycle leaves the factory, the shift wire and the brake wire are processed in a regular shape and wound between the front tube and the beam tube, but as the tube is exposed to the sun and rain for a long time, it becomes brittle and deformed, and the repeated switching of the transmission and braking The frequent pressing of the handlebars and the repeated rotation of the bicycle faucet will gradually displace and bend the shift wires and brake wires wound between the front tube and the beam tube, causing the front tube and the beam tube to be covered by irregular shift wires. The entang...

Problems solved by technology

[0005] Although the above-mentioned creation can adjust the angle of the elbow arbitrarily, so that the brake line is not limited by the angle of the bend as a setting, and can fix the brake line to the shape produced by the bend, but its overall structure is because the hard metal layer is a winding design. On the outer edge of the flexible metal layer, the distance between the hard metal layer cannot be effectively extended, and its ductility is greatly reduced. Therefore, when the brake cable or shift cable moves quickly in the bend, it cannot effectively eliminate the pull of the cable body. The vibration generated is easy to cause the bent pipe to quickly age and fatigue

[0006] In view of the fact that the above-mentioned bent pipe structure only has flexible shaping and lacks the effect of ductility, the inventor proposes a "bicycle wire tube structure", which is a bicycle wire tube structure with both flexibility and ductility. When providing bicycle brake cables, shifting cables and other cable assemblies, the cable tube structure can provide more variable flexibility adjustments and more flexible extension settings
