Description

The bicycle wire installation

Technical field

The utility model relates to a kind of bicycle wire installation, relates in particular to a kind of stationary pipes that has, so that the bicycle wire installation of fixing a wire socket effect to be provided.

Background technology

In the bicycle field, Derailleur Cable or brake lead are most important, particularly Derailleur Cable is controlled the speed that bicycle is advanced, and the brake line influences rider's personal safety especially, indiscreet and negligent especially must not, general Derailleur Cable is that an end is distributed on the located in connection structure of the forward and backward fork of vehicle frame with Brake cable, the other end around vehicle frame before pipe and beam tube and assemble in the change-speed box and the handle of braking, and be provided with a plastic tube body coated wire, prevent that to reach lead from exposing; Yet because this body is directly fixed on the location structure, this body can't rotate deflection arbitrarily, and bending causes the body breakage when operation easily, and lead is exposed and corrosion;

Therefore there is the dealer to propose to improve, please refer to the TaiWan, China patent application case: " the bend pipe holder structure improvement of bicycle brake " number No. 091200245, it is to be provided with a substrate in the bicycle brake, the substrate both sides be provided with the bevelled lateral margin in case with the binding that is pivoted of brake arm, and be provided with a plastic bend tube and replace and be locked on the substrate, and reach the function that the wide-angle rotation is moved;

Though existing wire installation is provided with plastic bend tube bigger bending angle is provided, but embrittlement easily because plastic bend tube drenches with rain through exposing to the weather for a long time, therefore the connecting bridge that is positioned at plastic bend tube and location structure is easy to generate damage rupture, plastic bend tube in-to-in brake lead or Derailleur Cable are exposed, not only make the lead corrosion easily, and can't carry out due operation smoothly, and owing to the easy winding of lead causes bicycle headstock to rotate smoothly, easier starting gives birth to danger, moreover, because this lead can't closely combine with bend pipe, so this lead is loosening easily, causes the damage of lead wearing and tearing and bend pipe.

Be with, at the existing problem points of above-mentioned existing wire installation, how to develop a kind of innovation structure that has more desirable practicality, the ardent hope of real customer institute also is that relevant dealer must make great efforts target and the direction that research and development break through;

In view of this, this creator is in manufacturing development and the design experiences of being engaged in Related product for many years, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicality.
