Abstract
The utility model relates to a rotary braking handlebar for a bicycle, which can be sheathed on a vehicle handlebar. The end part of the handlebar is sheathed on the bicycle handlebar at the part provided with a ratchet mechanism or a friction ratchet mechanism which can tightly rotate or loose a braking steel wire. The ratchet mechanism is composed of a ratchet connected with the handlebar into integration, a ratchet pawl ring provided with a ratchet pawl and a wire winding slot and a ring sleeve. The ring sleeve is sheathed on the end part of the handlebar and is fixed on the bicycle handlebar. One end of the braking steel wire is fixed in the wire winding slot of the ratchet pawl ring. A user only needs to rotate the handlebar to tighten or loose the braking steel wire by the ratchet mechanism in order to obtain the braking purpose. Braking operation is flexible and reliable and has no relationship with people's palm size. Thus the utility model is suitable for adults and children.
Description
The utility model belongs to bicycle manufacturing technology field.
Existing bicycle wire rope brake crank all adopts holds the formula structure, and when this kind structure was held handle with a firm grip as people, steel rope was tightened up, the wheel of always driving a vehicle thereby the drive brake gear is stopped; When unclamping handle, steel rope is loosened, and brake gear also loosens thereupon.Hold the formula structure because the adjusting wearing or featuring stage armour of steel rope degree of tightness on hand the leverage of lever realize that adjustable range has only the width of people's palm, so adjustable range is very limited; Lever is opened to such an extent that relatively open in addition, and children's palm is little, is not easy holding lever, so brake is very difficult, causes train operation accident easily.
The purpose of this utility model is that will to design a kind of leeway of regulating the steel rope degree of tightness big, safe and reliable, and adult, children's brake be the bicycle brake handle all easily.
Design goal of the present utility model is realized by following structure.The rotary brake crank of a kind of bicycle, it comprises handle, its main points are that handle is enclosed within on the handlebar, the handle end is enclosed within the ratchet device or the friction ratcher that can change tight or unscrew the brake steel wire rope is housed on the handlebar, one of its structure of ratchet device of handle end dress, it is by the ratchet that fuses with handle, the ratchet ring and the ring set that are provided with ratchet and wiring groove are above formed, the ratchet ring cooperates with ratchet, be enclosed within on the handlebar, ring set is enclosed within the handle end and is fixed on the handlebar, ring set is provided with the brake steel wire rope and introduces the hole, and brake steel wire rope one end is fixed in the wiring groove of ratchet ring.
The rotary brake crank of the bicycle of said structure, people's both hands inwardly rotate, and then ratchet drives the rotation of ratchet ring, and the wiring groove on the ratchet ring changes tight with the brake steel wire rope, thereby reaches the purpose of bicycle brake; Outwards rotate, then the ratchet ring is because the elastic pulling force of brake steel wire rope makes it also simultaneously to inner rotary, finally make steel rope place normal condition, brake is loosened, and adopts the rotary brake crank of this bicycle to be contained on the bicycle, regulates the distance of brake steel wire rope degree of tightness, so brake flexibility and reliability, and irrelevant in the operation with people's hand size, adult, children are all suitable.
The embodiment represented below in conjunction with accompanying drawing 1-2 is further described the utility model.
Fig. 1: the rotary brake crank structural representation of bicycle (cutaway view)
The A-A cutaway view of Fig. 2: Fig. 1.
Among Fig. 1-2: (1)---handle; (2)---ratchet device; (3)---ratchet; (4)---the ratchet ring; (5)---ring set; (6)---the brake steel wire rope; (7) handlebar; (8) ratchet; (9)---the wiring groove; (10)---steel rope is introduced the hole.
The represented embodiment of Fig. 1-2 goes up twist grip (1) and is contained in the ratchet device (2) that handle (1) end is enclosed within on the handlebar (7) and form by being enclosed within handlebar (7).Ratchet device (2) is made up of ratchet (3), ratchet ring (4) and ring set (5).Ratchet (3) is enclosed within handlebar (7) and upward and with handle (1) fuses, ratchet ring (4) is enclosed within on the handlebar (7), ratchet above it (8) matches with ratchet (3), ratchet ring (4) is provided with the wiring groove (9) that turns around brake steel wire rope (6), ring set (5) is overlapping ratchet (3) and ratchet ring (4) and is being fixed on the handlebar (7), and ring set (5) is provided with the introducing hole (10) of brake steel wire rope (6).
This embodiment is contained on the bicycle, will brake as bicycle, and handle (1) is inwardly rotated, and then ratchet (3) drive ratchet ring (4) rotates simultaneously, and the wiring groove (9) on ratchet ring this moment (4) changes tight with brake steel wire rope (6), at this moment bicycle brake.As bleeding off brake, then with handle (1) to inner rotary, then ratchet (3) and ratchet ring (4) are thrown off, also to inner rotary, brake steel wire rope this moment (6) restores to the original state ratchet ring (4) under the effect of brake steel wire rope (6) screen resilience, bicycle brake is released.From above-mentioned operation as can be known, this embodiment is safe and reliable, is not subjected to the influence of big or small palm in the operating process, and the adult children can operate easily.
