Description

Pull type bicycle speed changing controller

The utility model provides a kind of dial type bicycle shift controller, is meant a kind of simple element, handling good especially, and meets somatological novel variable speed control mechanism.

Existing variable-speed controller; its control mode all is to push two brakes (is that low speed becomes at a high speed, serve as that high speed becomes low speed) with rider's thumb in advancing; but because of the distance between two brakes by chance adjacent; and direction of action is identical again; therefore regular meeting has the situation that pushes the wrong brake to take place; this is for the cyclist, and in the keen competition of match, small again careless mistake promptly is the topmost factor of being defeated.

The purpose of this utility model is to overcome the shortcoming of prior art, invents a kind of user and can control driving lever and compacting bar, the dial type bicycle shift controller that the user can not dial the wrong number respectively in the motion of fierceness with thumb and forefinger.

The purpose of this utility model is achieved in that

A kind of dial type bicycle shift controller is made up of a cramp and a curved cramp on one group of control setup, the box body,, it is characterized in that:

There is a claw hook in cramp lower lip stage casing on it, and the appropriate location on end face right side is then dug and established a vertical runner, and a projection is set on bottom end face; Curved cramp left-hand end has a claw hook, and claw hook top rake has a stopper face, and this end face central part has a sideslip groove in addition, and right-hand end is one to extend and press bar;

When above-mentioned member after assembling is finished, the position of last cramp is higher than curved cramp, and the subregion overlaid is arranged between the two, go up the vertical runner of cramp and the sideslip groove of curved cramp simultaneously and all passed through, and located at proximal portion by an E shape clasp by the guide pillar that protrudes out on the box body; When normality, the claw hook of last cramp and ratchet sheet mesh usually, the claw hook of curved cramp then keeps an appropriate gap with the ratchet sheet, and its stopper face lower edge touches mutually with the projection of last cramp just in addition, and driving lever then extends to different directions respectively with the bar that presses of curved cramp.

The utility model advantage is: because the compacting bar of driving lever and curved cramp extends to same direction respectively, the utility model is installed to after the bicycle handle, the extended position of this driving lever will be than the thumb near the human body palm, the compacting bar is then than the forefinger near the human body palm, therefore the user just can thumb and forefinger control driving lever and compacting bar respectively, can not make the user that the sensation of obscuring is arranged, control simple and easy, clear and definite simultaneously; Handy during use.

Be described further below in conjunction with accompanying drawing.

Fig. 1 is an exploded perspective view of the present utility model;

Fig. 2 is the utility model combination stereogram;

Fig. 3 a is the utility model action scheme drawing;

Fig. 3 b is the utility model action scheme drawing.

As seen from the figure, it is made up of element such as cramp 40 and a curved cramp 50 on a box body 20, the control setup 30,, because its box body 20 and shape and pattern that need not be specific, so, there be a line hole 21, three perforation 22,24,26 and to protrude out guide pillar 28 on its end face only with a dull and stereotyped expression; Control setup 30 is by a driving lever 31, a line drum 32 and a thickening ratchet sheet 33, sees through relative rivet hole and is concatenated into one in regular turn by two rivets 34, cooperates a pin 35, a spring 36 and an E shape clasp 37 again and is hubbed in first perforation 22 of box body 20; On last cramp 40, there are a spring 41, a pin 42 and an E shape clasp 43 to be hubbed at by through hole 401 in second perforation 24 of box body 20, be positioned at the summary top of control setup 30, there is a claw hook 44 at its position, lower lip stage casing, the appropriate location on end face right side is then dug and is established a vertical runner 45, and a projection 46 is set on bottom end face in addition; There are a spring 51, a pin 52 and an E shape clasp 53 to be hubbed in the 3rd perforation 26 of box body 20 by through hole 501 on the curved cramp 50, promptly be positioned at the right edge of control setup 30 approximately, its left-hand end tool one claw hook 54, and claw hook 54 top sloping portions are stopper faces 55, this end face central portion then has a sideslip groove 56 in addition, and its right-hand end promptly is that an extension presses bar 57.

When above-mentioned member after assembling is finished, the position of last cramp 40 is higher than curved cramp 50, and the subregion overlaid is arranged between the two, go up simultaneously the vertical runner 45 of cramp 40 and the sideslip groove 56 of curved cramp 50 and all passed through, and located in the top by an E shape clasp 29 by the guide pillar 28 that protrudes out on the box body 20; When normality, the claw hook 44 and the ratchet sheet 33 of last cramp 40 mesh usually, the claw hook 54 of curved cramp 50 then keeps an appropriate gap with ratchet sheet 33, in addition its stopper face 55 lower edges touch mutually with the projection 46 of last cramp 40 just, and 31 of driving levers extend to different directions respectively with 57 on the bar that presses of curved cramp 50.

When the user push curved cramp 50 press bar 57 time, its claw hook 54 will be located with 33 engagements of ratchet sheet to bottom offset, also pushing tow projection 46 immediately of its stopper face 55 simultaneously, order about cramp 40 to top offset, thereby the claw hook 44 of cramp 40 and ratchet sheet 33 are broken away from, wait to loosen curved cramp 50, by spring 41,51 effect, two cramps 40,58 incite somebody to action return in regular turn, utilize two claw hooks 44 again, 54 potential difference, the claw hook 44 of last cramp 40 just mesh with next tooth position of ratchet sheet 33, and reach the purpose of gear shift, when desire is replied former grade of speed in addition, then need only pull driving lever 31 and get final product to the reversing sense displacement.

In addition, the guide rod 28 that is set firmly on the box body 20, its effect is for cooperating longitudinal and transverse chute 45,56 set on two cramps 40,50, to place restrictions on the actuating length of two cramps 40,50, with the stability of guaranteeing to move; The position in the set line of box body 20 one sides hole 21 exactly is a straight line with perforation 321 on the line drum 32 when the high speed gear, so that the user wears steel wire rope 60.

Because driving lever 31 extends to different directions respectively with the bar 57 that presses of curved cramp 50, make the utility model be assembled in bicycle handle bar on hand after, the extended position of this driving lever 31 will be than the thumb near the human body palm, press bar 57 then than forefinger place near the human body palm, therefore the user just can thumb and forefinger control driving lever 31 respectively and press bar 57, promptly as stirring abacus, the unlikely user of order has the sensation of obscuring.
