Bicycle cable assembly
View Patent ↗A bicycle cable assembly mainly includes an external protection tube composed of several hollow sleeves hooking together. Hooks and engaging edges of the sleeves hook together so that the external protection tube is formed and can be properly adjusted according to a length of a cable and a special position by increasing or decreasing the number of sleeves. Also, the hook hooking the engaging edge can prevent the external protection tube from being arbitrarily disassembled by others. Also, it is possible to effectively prevent an inner protection tube from exposing to the outside and thus being damaged. Thus, a protection layer can be indirectly added to the bicycle cable assembly.
1. A bicycle cable assembly, mainly comprising a cable, an inner protection tube covering the cable, and an external protection tube covering the inner protection tube, wherein:
the external protection tube is mainly composed of several hollow sleeves hooking together;
the sleeves comprise a first sleeve and a second sleeve; each of the sleeves comprises a first opening end and a second opening end; the first opening end is formed with a continuous flange around an opening of the sleeve; the flange extends slantingly outwards from an inner edge of the sleeve to form a maximum-diameter portion of the flange away from the opening; a hook is formed at the maximum-diameter portion, the second opening end is formed with a ring expanding outwards; the ring is for accommodating the flange, the ring comprises an inner edge and an outer edge, each of which has an outwardly expanded spherical shape; the ring is formed with an engaging edge extending inwards, a diameter of the engaging edge of the ring is smaller than a maximum outer diameter of the flange; and
the first opening end of the first sleeve can be inserted into the second opening end of the second sleeve slantingly, the hollow sleeves are engaged together to form the external protection tube, and the hook and the engaging edge hook together;
wherein the maximum outer diameter of the flange is smaller than 3/4 of a maximum inner diameter of the ring.
2. The bicycle cable assembly according to claim 1 , wherein the sleeve is made of a metal material.
3. The bicycle cable assembly according to claim 1 , wherein the inner protection tube is made of a plastic waterproof material.
4. The bicycle cable assembly according to claim 1 , wherein a length of the flange is smaller than ½ of a length of the ring.
5. The bicycle cable assembly according to claim 1 , wherein the cable is a brake cable.
6. The bicycle cable assembly according to claim 1 , wherein the cable is a shift cable.
