Abstract
The utility model relates to a labor-saving cable brake mechanism of a bicycle. The volume size of the utility model is similar with that of the present cable brake mechanism of the bicycle; the utility model is formed by a toothed-gear drive and a slide key locking device; under the condition without changing the other components of the bicycle, the cable brake mechanism is improved to save labor. Specially used in the children bicycle, the utility model can make the children brake easily. Having the locking function, the utility model is suitable for any with cable brake and can make the vehicles parking stably on any floors.
Description
The utility model relates to a kind of brake mechanism, and bicycle is stably stopped on the slope, and a kind of brake mechanism that can make that bicycle brakes easily.
Present known bicycle cable brake is directly to be affected cable wire and braked by handle, because the resistance of cable wire in noose is big, realize that very effort, especially child's bicycle adopt with a kind of cable brake with becoming person bicycle in braking, 4-6 year children just do not have dynamic braking, and its personal safety is not had reliable guarantee.When being parked on uneven ground or the slope, bicycle can produce sliding phenomenon.
The purpose of this utility model provides a kind of bicycle cable brake mechanism laborsaving and that lock everywhere, and it can not only make child's bicycle brake easily, and various cable brake vehicles can stably be stopped everywhere.
The purpose of this utility model is achieved in that in the can of 55 * 45 * 13mm, is made up of handle gear, half garden gear and locking card.When staff pinching handle, the handle gear is stirred half garden gear and is rotated, and designs as required at the R/2-R/3(of half garden gear) located a cable trough, by lever principle as can be known, handle is than the laborsaving 1/2-1/3 of existing mechanism.Locking is stuck in lid and is provided with a slide key, is connected with it by key pin, and when bicycle was parked in ground injustice or place, slope, thumb promoted slide key when clutching handle, makes to lock and blocks half garden gear, makes the cable wire can not be loose, checks vehicle lastingly.When the needs brake off, only pinch a lower handle, locking is stuck under the effect of spring and sets back.
Owing to taked such scheme, can make children can realize braking easily, also be applicable to any cable brake vehicle.Can also make any cable brake vehicle parking stable, and easy to operate, simple in structure.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is embodiment of the present utility model.
Fig. 2 is the view of lid and slide key among Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 only has the embodiment of the cable brake mechanism of lock function everywhere.
Fig. 5 is the embodiment that only has the cable brake mechanism of laborsaving function.
Among the figure 1, can, 2, lid, 3, the handle gear, 4, half garden gear, 5, the locking card, 6, spring, 7, the cable wire fix screw, 8,9,10 fixed rotating shafts, 11, slide key, 12, cable trough, 13, cable wire 14, feather key pin.
In Fig. 1, handle gear (3) is fixed by rotating shaft (9) and is meshed with the half garden gear of being fixed by rotating shaft (8) (4).Cable wire (13) is fixing by screw (7) by a cable trough (12) and an end.Locking card (5) is in original position under the effect of spring (6).During pinching handle gear (3), stir half garden gear (4) and rotate, thereby affect cable wire (13) to realize braking.1/2-1/3 because the radius of cable trough (12) is half garden gear (4) is than the present known cable brake laborsaving 1/2-1/3 of mechanism.
When vehicle is parked in uneven ground.When especially being parked on the slope, clutch handle (3), half garden gear (4) rotates thereupon, affect cable wire (13) to make car brakeing, thumb promotion slide key (11) makes locking card (5) block half garden gear (4) by feather key lock (14) simultaneously, when opening handle, half garden gear (4) is at the restoring force effect lower compression locking card (5) of cable wire (13) when openhanded, and making it can not reposition.When needing brake off, only pinch a lower handle (3), half garden gear (4) rotates the compressing power of removing thereupon.Locking card (5) restores under the effect of spring (6) automatically simultaneously.
Principle according to this machine can be designed to left hand and right hand brake mechanism, and its structure size equates symmetrically.Also can be designed to only have the single institution of laborsaving or lock function.Half garden, one end of handle in the accompanying drawing 4 (3) has a gear or multiple tooth, pinching handle (3) promotes the tooth that slide key (11) makes locking card (5) block handle (3) one ends simultaneously and lacks, when needing brake off, pinch a lower handle (3), locking card (5) reposition under the effect of spring (6).In the accompanying drawing 5, handle gear (3) and the engagement of half garden gear (4), fix screw (7) affects cable wire (13) by cable trough (12), reaches the labour-saving purpose.
Claims (2)
1, a kind of cable brake mechanism, directly affect cable wire by handle, it is characterized in that: in rectangular box, handle gear and half garden gear are fixed and are meshed by rotating shaft, and have laborsaving and the bicycle cable brake mechanism of locking everywhere by slide key and key pin and the combination of locking card a kind of.
2, bicycle cable brake mechanism laborsaving and that lock everywhere according to claim 1, it is characterized in that: on the half garden arc of handle one end one or more teeth are arranged, locking card and slide key are formed.
