Abstract

A bicycle disc brake structure comprises a disc mounted between upper and lower brake pads in a main body and a clamp cover, wherein a rear cover, the clamp cover and a compensation screw are connected integrally by a rotating shaft to form a rear hand-adjusted cover; and a pull rod and a driving disc connected with a spring, a fixed disc, a hold-down nut and a steel ball are connected integrally by an adjusting shaft and a middle shaft. The bicycle disc brake structure further comprises a front hand-adjusted cover mounted on the adjusting shaft, wherein the front hand-adjusted cover has the structure that an elastic piece mounted in the front cover and a front grab on the front cover are matched with an anti-loosing gasket mounted on the driving disc and the adjusting shaft is connected with the front cover. The spacing between the brake pads is adjusted through manual operation instead of a tool, and the spacing can be adjusted in upper and lower parts respectively or separately; therefore, the bicycle disc brake structure is flexible and quick for use and adjustment; front and rear grabs are arranged on the front and the rear covers, so that the front and the rear covers are not easy to drop; and simultaneously, the rear cover and a projection on the elastic piece are matched with grooves formed in the clamp cover and the anti-loosing gasket so as to prevent autorotation of the front and the rear hand-adjusted covers; therefore, automatic displacement of the brake pads is prevented and the bicycle disc brake structure is safer and more reliable for use.

Description

The Bicycle dished brake structure

Technical field

The utility model relates to the Bicycle dished brake structure that a kind of available hand is regulated bicycle brake sheet spacing.

Background technology

Bicycle brake has multiple various structure, mechanical type disc brake especially, and its brake facing is easy to rub disc, therefore needs often to go to regulate with instrument hex spanner or other instrument the position of brake facing, brings inconvenience to the bicycle user.

Though a kind of structure with manual regulation brake spacing also is provided, only can there be certain limitation in it at folk prescription to adjusting to the patent No. 201020278323.4 " but Bicycle dished brake clamp of hand adjustment brake spacing ", uses also inconvenient.

Summary of the invention

The utility model technical matters to be solved is: a kind of Bicycle dished brake structure is provided; When not influencing braking effect, make the installation of disc brake and debug more convenient, quick, just manually actuated without instrument; Debugging has simultaneously easily also prolonged the service life of disc brake.

The technical scheme that the utility model addresses the above problem employing is: the Bicycle dished brake structure; Comprise the disc between the upper and lower brake facing that is installed in main body, the caliper lid; Hand adjustment was covered after rotating shaft connected into single-piece with bonnet, caliper lid, compensation screw; Adjusting shaft, axis connect into integral body with pull bar, the driving disk that is connected with spring, price fixing, hold-down nut, steel ball, also comprise the preceding hand adjustment lid that is installed on the adjusting shaft, said before the hand adjustment lid by the shell fragment and the preceding grab on the protecgulum that are installed in the protecgulum; Cooperate with the check washer on being installed in driving disk, and adjusting shaft and protecgulum connect and compose.

Compared with prior art, the advantage of the utility model is: this disc brake structure is equipped with back hand adjustment lid, direct control by hand except that covering at caliper; Outside the spacing of instrument with regard to the scalable brake facing, hand adjustment lid before also on the pull bar of the top of driving disk, installing, also available herein manual operations; The replacement instrument is regulated the spacing of brake facing, and upper and lower two places can regulate simultaneously or upper and lower two places regulate respectively, uses the adjusting alerting ability good; How no limitation makes things convenient for, how to regulate, and satisfies different demanders' requirement; Forward and backwardly in addition covered forward and backward grab, made forward and backward lid difficult drop-off, bonnet covers with projection and caliper on the shell fragment simultaneously, the groove on the check washer works in coordination; Prevent the rotation of forward and backward hand adjustment lid; Thereby avoid, prevent the brake facing automatic shift, though fluted more shallow on the caliper lid, check washer, can guarantee that also just can directly rotate forward and backward hand adjustment with the strength of hand covers and operate, regulate.

The specific embodiment

Further describe below in conjunction with the enforcement of accompanying drawing the utility model.

Have on the side inwall of bonnet 16 be uniformly distributed with, the projection 22 of circular arc, lower edge has inside back grab 23, there is profile hole 24 centre, promptly two limits are parallel straight line, both sides are the through hole that relative circular arc constitutes.

In the middle of the caliper lid 15 screw is arranged, the groove 21 and annular groove 19 that are uniformly distributed with are arranged on the outside face.

The profile hole 24 on compensation screw 18 and the bonnet 16 is passed in rotating shaft 17; Bonnet, compensation screw are connected into integral body; Compensation screw 18 covers 15 intermediate thread with caliper and is connected, and the back grab 23 on the bonnet 16 is embedded in the annular groove 19 that caliper covers, the bonnet difficult drop-off; Projection 22 on the bonnet 16 cooperates with the groove 21 that caliper covers on 15, prevents that the rotation of bonnet from constituting back hand adjustment lid.

In the middle of the check washer 3 the special-shaped through hole 29 identical with profile hole 24 shapes arranged, the arc groove 28 that is uniformly distributed with is arranged on the periphery, check washer is connected the ladder place of driving disk 10 upper ends with special-shaped through hole 29 flush fits on it.

The four preceding grabs 25 that are uniformly distributed with are arranged on protecgulum 6 inwalls; There is profile hole 26 centre; In the middle of the inwall boss place install with preceding grab dislocation side by side on have the reed of arc convex 27 to constitute shell fragment 4, the arc convex 27 on the shell fragment 4 is connected integral body with arc groove 28 on the check washer 3.

Adjusting shaft 5 lower ends are for being with externally threaded circular bar shape, the lower end of the upper end of adjusting shaft 5 and rotating shaft 17, be respectively with protecgulum 6, bonnet 16 on the special-shaped flat bar that cooperates of

profile hole

26,24.

The profile hole 26 on the protecgulum 6 is passed in adjusting shaft 5 upper ends, and protecgulum 6, check washer 3, shell fragment 4 are connected into the whole preceding hand adjustment lid that constitutes.

During use, as required, cover or regulate simultaneously forward and backward hand adjustment lid with hand adjustment lid or back hand adjustment before the hand adjustment joint.

Rotate protecgulum 6 with the hand clockwise direction, drive with it and connect into 5 rotations of single-piece adjusting shaft, tween drive shaft 11 is moved down; Brake facing 12 moves down in the promotion; Regulate the distance between brake facing, opposite sense rotates protecgulum, then promotes to go up brake facing 12 and moves up.

If rotate bonnet 16 with the hand clockwise direction; Drive connects into single-piece rotating shaft 17 and rotates with it; Drive upwards rotating of compensation screw 18 through rotating shaft, compensate screw simultaneously and promote down that brake facing 14 moves up, regulate the distance between brake facing; Opposite sense rotates bonnet, then descends brake facing 14 to move down.

Directly save forward and backward hand adjustment lid, thoroughly break away from the constraint of instrument, let the cycling person use, regulate more flexible, quick with hand adjustment.
