Description

Bicycle brake line locking structure

Technical field

The utility model relates to a kind of bicycle brake line structure, refers in particular to a kind of locking structure of bicycle brake line.

Background technique

Generally speaking, bicycle is connected with a braking string (promptly outer cover is covered with the brake cable of glue-line) with brake lever and by affecting braking string to make to be fixed in addition the brake of end to produce the folder of the wheel rim only wheel of pulling and stop.And the means of fixation of general braking string, normally by with the direct packing braking string of bolt, it is right because the brake cable of braking string is to be formed by most bar finer wire harnesses, if therefore use the mode of direct packing, even increasing torsion between then common because bolt end and the braking string and twist to twist and dial from this finer wire, causing braking string torsional deformation or fracture to cause can't reuse.Therefore, just again the someone develop with pad and grip braking string and it is fixed.Yet, pad also must be locked and establish bolt, and traditional type is exposed to outer bolt head, not only influence the integrity of whole brake structure outward appearance, also collude braking string or rider's clothing easily because of the structure of its protrusion, though can avoid the distortion of braking string excessive distortion, still existing the utmost point needs improved space.

The model utility content

It is a kind of easy to use, safe that the purpose of this utility model is to provide, and the complete bicycle brake line locking structure of outward appearance.

For achieving the above object, the utility model adopts following structure:

A kind of bicycle brake line locking structure, wherein, include a positioning part, be formed with a perforation on this positioning part, the direction of this perforation axis is according to the installation direction setting of braking string, in this positioning part and be formed with a positioning hole that is communicated with perforation and one with the screw of boring a hole and being communicated with, this screw also extends to the surface of positioning part, this positioning hole and screw are positioned on the same axis, and this axis and with the perforation orthogonal axe; An and wire-clamping device that is installed in the positioning part, this wire-clamping device includes one first fixture block, one second fixture block and a compression element, this first fixture block is positioned in the positioning hole and extends in the perforation, this second fixture block activity is hubbed on the axis of compression element, this compression element also is formed with outside thread and a multiform hole, make things convenient for the user to utilize the tool operation compression element, make compression element can utilize screw to force the end thrust of second fixture block, move and urgent folder braking string towards first fixture block not rotate thereupon.

Described positioning part must be located at can be for any position that braking string ran through and fixed between brake lever and brake binder.

Described first fixture block is handled through embossing with the end face that second fixture block contacts with braking string and is provided with lines, uses the frictional force that improves between two fixture blocks and braking string.

By this, because second fixture block axially is hubbed on the compression element, therefore when its with after braking string contacts, only can rotate and can not rotate with respect to compression element with respect to braking string, can effectively avoid braking string torsional deformation or dial in fixing process from steel wire, again since after the installation whole wire-clamping device all be hidden in the positioning part, make that the braking string locking structure is that one to hide its outward appearance of kenel complete, and the non-bolt evagination goes out phenomenon and more can not collude the clothing that touch the rider.

The primary clustering symbol description

11 perforation of 10 positioning parts

Embodiment

The utility model is relevant for a kind of bicycle brake line locking structure, sees also Fig. 1 to shown in Figure 4, and it consists predominantly of a positioning part 10 and and is installed in wire-clamping device 20 in the positioning part 10.

Be formed with a perforation 11 on this positioning part 10, the direction of these 11 axis of boring a hole is according to the installation direction setting of braking string 30, can avoid crooked and smooth and easy when influencing braking string 30 starts of braking string 30.Be formed with in this positioning part 10 one with perforation 11 positioning holes that are communicated with 12 and one with bore a hole 11 screws that are communicated with 13, this screw 13 also extends to the surface of positioning part 10.Wherein, this positioning hole 12 is positioned on the same axis with screw 13, and this axis and with the orthogonal axe of perforation 11.

This wire-clamping device 20 includes one first fixture block 21, one second fixture block 22 and a compression element 23.This first fixture block 21 is positioned in the positioning hole 12 and extends in the perforation 11.This second fixture block 22 is hubbed on the axis of compression element 23.This compression element 23 also is formed with outside thread and a polygonal hole 231 makes things convenient for the user to utilize tool operation compression element 23, make compression element 23 can utilize screw 13 to force second fixture block 22 to move and clamp the braking string 30 of bicycle, as Fig. 4 and shown in Figure 5 towards first fixture block 21.In order to increase the frictional force of 30 of two

fixture blocks

21,22 and braking string, the end face that two

fixture blocks

21,22 contact with braking string 30 is handled through embossing.This first fixture block 21 is identical with the structure of second fixture block 22, is all the structure of a T type, uses the area of contact that increases by two

fixture blocks

21,22 and braking string 30.See also as shown in Figure 3 and Figure 4, this second fixture block 22 utilizes the mode of riveting that its afterbody is extended out again and avoids second fixture block 22 to come off on compression element 23 after extending into polygonal hole 231.

When desire is used the utility model, see also as Fig. 4 and shown in Figure 5, at first utilize perforation 11 to run through positioning part 10 braking string 30, rotate compression element 23 again, the direction of utilizing the internal and external threads cooperation to order about second fixture block, 22 past first fixture blocks 21 moves, since second fixture block 22 be axial play be hubbed on the compression element 23, and only have end thrust not with rotation, therefore when its with after braking string 30 contacts, can't rotate with respect to braking string 30, can effectively avoid braking string 30 torsional deformation in fixation procedure, again owing to whole wire-clamping device 20 after the installation all is hidden in the positioning part, make that the braking string locking structure is the complete clothing that can not catch on its person of taking advantage of of an outward appearance, can thoroughly solve the shortcoming of commonly using the braking string locking structure.

In addition, must be illustrated, bicycle brake line locking structure of the present utility model, wherein, the positioning part is located between brake lever and brake binder, can be for any position (as brake lever, stop arm or middle linking block etc.) that braking string ran through and fixed.

The above is only implemented in order to explanation the utility model, is not in order to restriction the utility model, so the displacement of the change of numerical value or equivalent elements must be subordinate to category of the present utility model such as.
