The auxiliary brake cable is provided respectively with a first portion and a second portion, a mediation device is connected between two portions, wherein, one end of the second portion is connected with the brake, and the other end of the second portion then is screwed in the mediation device. The corresponding position of the second portion and the mediation device can be adjusted by rotating the mediation device.
Description
The utility model relates to a kind of bicycle brake line, refers to a kind of length-adjustable brake cable especially.
The structure of the bicycle brake line of Shi Yonging now, its combination view is presented among Fig. 5, it is the brake 50 that respectively is pivoted in the both sides of front fork 60, its relative inner is respectively established a brake shoes 501, be sheathed on the spacer 53 for clamping wheel 70, one auxiliary brake lines 52 stage casing parts, its two ends combine with a bolt 51 respectively, the shaft of this bolt 51 is provided with perforation (figure do not show) and can penetrates for an end of this auxiliary brake line 52, and this bolt 51 is screwed in the brake 50 again and it packing is located.And spacer 53 is connected with an end of main brake line 54 in addition, its in addition end be connected with brake crank (figure does not show), make when this brake crank of pulling, spacer 53 upwards will be pulled and makes auxiliary brake line 52 spur an end of brakes 50 and make brake shoes 501 reach the purpose of brake to wheel 70 clampings.Such structure when using one section in the future auxiliary brake line 52 can produce lax phenomenon with respect to brake 50, have following shortcoming during adjustment and produce:
(1) must transfer bolt 51 on the other hand, other pulls moving auxiliary brake line 52, in the action not tool make things convenient for simplification, general user is not easy to operate.
(2) the terminal regular meeting of auxiliary brake line 52 perforation of when bolt 51 is unscrewed, deviating from bolt 51, and because auxiliary brake line 52 for the multi beam steel wire coil around a cable wire that forms, its end often forms the multiply forked, is difficult for being penetrated by this perforation place again, increases puzzlement on foot.
(3) auxiliary brake line 52 ends of above-mentioned bifurcated very easily cause user's hand injured.
Because commonly use many shortcomings of brake cable, main purpose of the present utility model is: a kind of extra instrument that do not need is provided, only rotate single element and just can reach the length-adjustable brake cable of adjusting the brake cable degree of tightness, mainly the auxiliary brake line is divided into first and second portion, both connect with intermediary's device, with first's socket, with second portion then for being spirally connected, make when need adjusting, only need rotate this intermediary's device just can be because of with the relation of being spirally connected of second portion and reach relative motion, and then can reach the purpose of adjusting degree of tightness.
The purpose of this utility model reaches as follows:
A kind of length-adjustable brake cable, wherein main brake line one end is connected with a spacer, and end is connected with brake crank in addition, and a caulking groove is respectively established in the spacer both sides, and caulking groove is connected with an end of auxiliary brake line, and the end in addition of auxiliary brake line is connected with brake; It is characterized in that: the auxiliary brake line is made of first, second portion and intermediary's device, wherein first's one end forms scarf joint and spacer interlocking, end forms the termination in addition, and second portion one end formation scarf joint is connected with brake, and end then forms the end that is spirally connected in addition; The distolateral limit of intermediary's device one forms a fluting, and is terminal then to have than the first termination be little opening, and the termination of interlocking first, and end forms being spirally connected of screw and second portion and holds and be spirally connected in addition.
The purpose of this utility model can also following mode reach: described length-adjustable brake cable, it is characterized in that: described intermediary device is made of intermediary's body and first nut and second nut that are bolted in intermediary body two ends, wherein first nut is with respect to the first of auxiliary brake line, the one side forms fluting, end face forms opening, and second nut is with respect to the second portion of auxiliary brake line, and the one side forms fluting.
Effect of the present utility model is: when needs are adjusted the brake cable degree of tightness, instrument that need not be extra, only rotate intermediary's device and can make second portion and intermediary's device generation relative displacement of auxiliary brake line, thereby can adjust the degree of tightness of brake cable, for the cyclist provides very big convenience.
For further specifying structure of the present utility model, feature and practical purpose thereof, the following drawings describe in detail as the back:
Fig. 1: be unitized construction scheme drawing of the present utility model.
Fig. 2: be the partial enlarged drawing of Fig. 1.
Fig. 3: be element exploded view of the present utility model.
Fig. 4: be running condition scheme drawing of the present utility model.
Fig. 5: be existing brake cable textural association planar view.
Architectural feature of the present utility model, please cooperate and consult Fig. 1, Fig. 2 and shown in Figure 3, one main brake line, 101 1 ends are connected with brake crank (figure does not show), end then is connected on the spacer 10 in addition, and a caulking groove 11 is respectively established in spacer 10 both sides, can be for the usefulness of auxiliary brake wire joint, alleged auxiliary brake line is divided into first 20 and second portion 30, first's 20 1 ends form a scarf joint 21, can be chimeric with the caulking groove 11 of spacer 10, and end forms a termination 22 in addition.Second portion 30 1 ends formation one is spirally connected and holds 32, and end is then established a scarf joint 31 in addition, and this scarf joint 31 can be fastened in middle location of relative caulking groove (figure does not show) of brake 80.
One intermediary's device, it can be the combination of intermediary's body 40 and first, second nut 23,33, and intermediary body two ends form the double- screw bolt 43,44 of projection respectively, wherein hold 32 double-screw bolt 44 inner faces formation screw 41 at least with respect to being spirally connected.But these double- screw bolt 43,44 relative engagement first and second nuts 23,33, first nut, 23 side tools, one fluting 24, can be inserted in from this fluting 24 for first 20, and the opening 231 of these first nut, 23 1 ends is little than termination 22 diameters of first 20, and first 20 is combined with first nut 23.Second nut, 33 sides are provided with a fluting 34 equally, can embed for second portion 30, and the end 32 that is spirally connected of second portion 30 then is screwed into location in the screw 41 of intermediary's body 40, and first and second nuts 23,33 are bolted in respectively on the double- screw bolt 43,44 of intermediary's body 40.
See also Fig. 4, when spurring brake crank when brake, spacer 10 just upwards spurs first 20, intermediary's body 40 and second portion 30, and then brake is rotated and make brake shoes 81 clamp wheel 90.And when needs were adjusted the auxiliary brake line, only the direct turn of need intermediary body 40 just can make be spirally connected end 32 and 41 generations of screw relative motion of second portion 30, and can reach the purpose of adjustment easily.
