Embodiment

The present invention is a kind of switching lubricating structure that is applied to brake lines such as bicycle or locomotive; Be able to reduce friction when receiving the brake structure interlock with brake line outer tube in order to the inner cable wire of brake line; And then obtain a good brake interlock; See also Fig. 1 to shown in Figure 4, the lubricated exchanging structure of this conduit comprises a joint seat 1, a dry type bearing 2 and a plurality of Coupling 3

These joint seat 1 two ends are respectively equipped with and supply different Coupling 3 movable first connecting end 11 and second connecting ends 12 that are provided with; This joint seat 1 is provided with the first binding mouth 13 that a confession brake line 4 plugs in first connecting end 11; This joint seat 1 is surrounded with a ring protuberance 14 in first connecting end, 11 outer rims in addition; This joint seat 1 is provided with one second in second connecting end 12 and links mouth 15, and this joint seat 1 links mouthful 15 inner rings in second in addition and is wound with a circular rabbet 16;

This joint seat 1 inside is provided with a built-in space 17 and a through hole 18 between first binding mouthful 13 and second binding mouth 15; This through hole 18 links between mouth 15 and the built-in space 17 second; And the first binding mouth 13, second of joint seat 1 links mouth 15, built-in space 17 and through hole 18 and presents the conducting aspect; This built-in space 17 supplies dry type bearing 2 that usefulness is set; This through hole 18 supplies brake lines 4 cable wires 41 break-through usefulness, and the internal diameter in this built-in space 17 links mouthful 13 and second less than first and links mouth 15 in addition, and the internal diameter in this built-in space 17 is greater than through hole 18;

This dry type bearing 2 is the Coupling of a teflon material, and this dry type bearing 2 is provided with the perforation 21 that 41 break-through of a confession brake line 4 cable wires are used;

This Coupling 3 is provided with that one first binding end 31, one second binding end 32 and run through first binding end 31 and second binding end 32 and as the wire casing 33 that supplies 4 break-through of brake line; These first binding end, 31 outer rims are provided with one and supply to be forced into the ring flank 311 that is fixed in circular rabbet 16, and this second binding end 32 is wound with one in wire casing 33 inner rings and supplies ring protuberance 14 or ring flank 311 to be able to be forced into fixing annular groove portion (not shown);

Whereby, when brake line 4 inner cable wires 41 received brake apparatus to involve action, this cable wire 41 was able to obtain a comparatively sliding suitable displacement through dry type bearing 2; With the friction of reduction with brake line 4 outer tubes 42; And then obtain a good brake interlock, and this Coupling 3 is coated on brake line 4 outsides according to the consecutive set-up mode and more can effectively protects brake line body, be with; Be arranged on the brake wire rod with equidistant mode through the present invention's " conduit lubricates exchanging structure "; Be to provide brake line cable wire to reduce the friction with outer tube really, obtain a more smooth-going action, and then obtain a good brake interlock.
