Description

The C for having tension disc presss from both sides brake

Technical field

The utility model is to press from both sides to brake about C, particularly relates to the dynamic tension disc of turn screw band and clips brake wire positioning, and Release brake wire is unscrewed, help that brake wire is installed and replaces brake wire.

Background technique

Bicycle is widely used short distance running vehicle in human lives for a long time, tramples and steps on by both feet Plate provides power drive chain-driving rear-wheel, can keep travelling route forward.If in order to which bicycle slows down or stops completely, It is then the brake pull rod for withholding arranged on left and right sides on handle, drives front and rear wheel brake friction pulley frame two respectively by brake pull rod The disc of side or friction wheel.

Bicycle brake device common at present includes the brake of C folder, cantilever brake, V evil spirit, disc brake etc..The brake of bicycle Device is there is still a need for actual use driving situa-tion, road conditions is considered, to select type of suitably braking.Since racing type highway car is travelled Road surface be mostly smooth tarmac road surface, relatively often configuration C folder brake, under brake wire tension, unilateral brake arm is inwardly clamped, And the brake block of brake arm one end is made to clamp wheel rim.

Be currently known C folder brake No. 568623 just like TaiWan, China patent of invention I vehicle bands formula actuating system, TaiWan, China new patent M532423 bicycle brake, TaiWan, China new patent M519112 bicycle brake Adjustable quick-disassembly structure, the patents such as this are directly to be fixed with bolt packing crimping plate surface to fixed brake wire mostly.

Utility model content

Technical problem underlying to be solved in the utility model is, overcomes drawbacks described above of the existing technology, and mentions Brake is pressed from both sides for a kind of C for having tension disc, screw is adjusted to drive tension disc by turn, allows tension disc along the axial direction of adjustment screw Direction unscrews brake wire to clip brake wire positioning and release, is conducive to the installation brake wire and replacement brake wire of C folder brake.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of C having tension disc presss from both sides brake comprising an outer clamp arm, the fixed group of clamp arm, a brake wire in one, in which: be somebody's turn to do There is opposite direction to configure a first end and a second end for the outer arc-shaped shape of clamp arm, the outer clamp arm, which is simultaneously assembled with one Brake block, and the second end has two forks, and has a short slot between two forks, two fork and the short slot group connect the brake Line fixes group；The interior clamp arm has a third end and one the 4th end for opposite direction configuration, which is assembled with a brake block, The interior clamp arm is hubbed at position between the first end and second end of the outer clamp arm with the 4th end part, and the 4th end is equipped with outward An extended segment, the extended segment be equipped with brake wire perforative one penetrate screw；The fixed group of the brake wire include an adjustment screw, One positioning seat and a tension disc；The positioning seat has two lugs, and a positioning groove is equipped between two lug, and two lug is all Equipped with a perforation, and the perforation is connected to the locating slot, and the locating slot has opposite one to compress groove face and a release groove face；It should Tension disc is located in the locating slot, and the tension disc is equipped with a screw hole of the corresponding perforation, which is equipped with a groove, And this is corresponded to the groove and compresses groove face；The adjustment screw wears two fork and the perforation and is screwed together in the screw hole, forward direction rotation It moves the adjustment screw and drives the tension disc, so that the tension disc compresses slot towards this in the axial direction in the locating slot along the adjustment screw Face is mobile, and it is in clip brake wire side relatively that the groove, which compresses groove face with this,；The opposite direction turn adjustment screw band dynamic pressure line Plate, so that the tension disc is along the axial of the adjustment screw in the locating slot towards the release groove face in moving, and brake wire is from the pressure Line plate is detached from.

The utility model has the beneficial effects that adjusting screw by turn to drive tension disc, allow tension disc along adjustment spiral shell The axial direction of silk unscrews brake wire to clip brake wire positioning and release, is conducive to C and presss from both sides the installation brake wire braked and replace Change brake wire.
