Abstract

The utility model relates to a device of improved bicycle brake control handles which transfer braking starting force by steel wire. A crank link mechanism is composed of a handle bar jacket with a pin hole and a slot, a small handgrip, and a yoke plate which glides along an open slot at the end of the handle bar jacket. The crank link mechanism draws a wire rope from the end of the conduit which is fastened in a handle bar tube by an expanding sleeve, which realizes braking. The conduit stretches out from an opening in the middle of the handle bar and leads to the braking parts. The utility model has the advantages of simple structure, small size, good appearance, strong braking force, soft handle, and good resistance to braking distortion caused by separation of wire joints.

Description

Bicycle handles

The utility model is the improvement about the bicycle control handle of steel wire transmission braking starting power.

So far, when using the brake of steel wire gate bicycle brake, particularly when sudden stop, cause being still within the bounds of possibility of brake failure danger because of collapsing lock.Its major cause is that the riveted joint of joint on the steel wire gate handle and steel wire end or welding process intensity are held sometimes and be can't stand steel wire pulling force and get loose.In addition, existing handle arrangement lever force because of exposed natural rust effect has also increased friction drag, makes steel wire transmission braking starting power be subjected to certain restriction than the steel wire end that does not include too big and handle.

Task of the present utility model is to improve the technology that is connected of handle and steel wire end, in order to bear the maximum brake holding load of steel wire, avoids therefore and the brake failure possibility of generation.And improve handle arrangement and brake application curve and change, improve the effective braking force and the leak tightness of handle.

Its solution is the handlebar grip of band pin-and-hole and slotted eye, the handlebar grip that also only is provided with slotted eye that clip perhaps is housed is inserted in the end and has otch, and on the handlebar of the wired pore in middle part, yoke plate is connected by bearing pin with the steel rope that is stretched out by the solid conduit end of ringfeder and tapered jam-pack from handlebar tube, and with miniature lever, handlebar grip form open slot with the handlebar tube port part be chute can haulage cable piston crank mechanism.

Maximum characteristics of the present utility model are piston crank mechanisms that miniature lever in the handle and yoke plate are formed by handlebar mouth of pipe groove slideway, and its braking action power changes by sinusoidal rule.Its effective braking force is bigger, and brake firmly feel is better.

Great advantage of the present utility model is that the power of being fastenedly connected that yoke plate in the handle and steel wire end are sold axle and nut can be born the maximum brake holding load of steel wire and can not be got loose, and has avoided because of collapsing the brake failure phenomenon that lock causes.In addition, keep big distance and hinged connection mode thereof between bearing pin and the spool port and all help reducing crooked amplitude of steel rope work and wearing and tearing, reduce brake resistance.

Another advantage of the present utility model is to have made full use of the ccontaining spool of space condition in the bicycle handle bar pipe, make the outward appearance of bicycle handle bar rationally distributed and more practical (being convenient to take the extension school bag), simplify and dwindled the handle brake part, improve the sealing property of handle, helped prolonging the service life of spool and handle component.

The open slot that another characteristics of the present utility model are handlebar pipe ends also plays the positioning action that prevents the handlebar grip twisting except that for the effect of yoke plate mobile guide.

Further improvement of the utility model is because handle bears in the handlebar tube wirerope axis to relative working pulling force, the handlebar grip of having avoided may occurring in the prior art phenomenon that gets loose.

Introduce an embodiment of the present utility model with reference to the accompanying drawings:

See figures.1.and.2,1. cut a width below the port greater than 7. (Fig. 5) thickness of yoke plate in handlebar tube, length is greater than the open slot of yoke plate work moving range, 2. spool is stretched into from the spool hole of handlebar midway location (Fig. 8) termination, stretch out from the handlebar port again, the tapered plug of online pipe end suit is (Fig. 7) 3., ringfeder is (Fig. 6) 4., together pushed up go back to appropriate location in the handlebar tube by special tool (not drawing) then, traction still is retained in the outer steel rope of handlebar tube port and 8. impels spool to move outward, make the spool termination in the tapered plug be tightened fixing, with handlebar grip 9. (Fig. 3) pack into earlier handlebar tube approximately half, the steel wire end is extracted from the handlebar grip slotted eye, pass bearing pin (Figure 11, a) hole, with nut with bearing pin 5a, pin sleeve 5b(Figure 11, b) the fastening yoke plate hole that is hinged on.Returning when leading steel rope toward the handlebar tube port, yoke plate upper end and annex are drawn in the handlebar grip slotted eye enters handlebar tube, the protruding axle of yoke plate is injected in the handlebar tube open slot with the upper part, again handlebar grip all is inserted in handlebar tube, 6. two holes on (Fig. 4) are hinged with handlebar grip pin-and-hole, yoke plate pin-and-hole respectively with miniature lever at last.Glancing impact was held miniature lever, is ordered about the handlebar tube open slot slideway slip that the protruding axle of yoke plate appears along handlebar grip notch place after handle and brake were installed and adjusted, constituted the piston crank mechanism haulage cable braking that braking force changes by sinusoidal rule, the minimum angle of the braking of this crank connecting link should be greater than hysteresis from the locking angle.

Introduce another embodiment of the present utility model with reference to the accompanying drawings:

With reference to Fig. 9, present embodiment and above-mentioned difference are that 9. handlebar grip is gone up and do not established pin-and-hole, adorn a clip 10. on handlebar grip port limit, and utilize fastening clip hinged with screw and miniature lever.In addition, can also adopt (Figure 10) way, with clip

Be fastened on screw on the handlebar tube of handlebar grip port, the screw and the miniature lever that utilize fastening clip to use are hinged.

Claims
