Shift handle

The invention relates to a shifting handle, which is used for shifting a bicycle. The rider dials the shifting lever, the reverse lever and the single reverse lever to drive the ratchet gear shifting mechanism to release and release the ratchet gear. The shifting line seat on the mechanism pulls the shifting cable and releases the shifting cable to complete the purpose of shifting and retracting. The invention also has the functions of fast forward, reverse and single return.

Cycling has become a more popular way of leisure sports. The bicycle industry continues to improve its components in terms of leisure, recreational sports, competitions, etc., especially for braking, or shift control. In order to meet the needs of the public, there have been many innovative designs in the bicycle industry in recent years.

According to the general bicycle shifting mode, the shift cable is combined with the ratchet gear shifting mechanism and the shift lever operation mode, and the shift lever is used to drive the ratchet gear shifting mechanism to complete the shifting and retracting purposes. In operation, the ratchet gear shifting mechanism is driven by the shift lever to cause the flywheel to advance to a gear. If multiple gears need to be changed, the shift lever should be continuously moved, and the shifting of multiple gears cannot be performed in a single stroke. All of the above-mentioned lacks have the necessity of improving the conventional shifting handle.

In view of this, the inventors are well aware of the lack of use, and have been modified and improved, while at the same time pursuing a good spiritual concept, and through its many years of professionalism The field of experience, and ingenuity, after testing, finally successfully tested the invention to provide a shifting handle.

The main purpose of the present invention is to provide a shifting handle provided on a bicycle handlebar and connected to a shift cable to a rear derailleur, which is wound on a shifting wire base of a ratchet gear shifting mechanism by a shift cable. When the passenger dials the shift lever, the reverse lever and the single retract lever, the ratchet gear shifting mechanism can pull the shift cable and release the shift cable to complete the shifting and retracting purposes, and the brake handle is dialed to the inside. It has the function of braking when moving, and has the function of retracting when it is pushed up. When the shifting lever is pushed, it can enter multiple files. When the handle is turned, it can be retracted. When the single retracting lever is used, it can be retracted. In the operation, after the ratchet gear shifting mechanism is driven by the shifting lever, the shifting line base will scroll the shifting cable clockwise, so that the chain on the flywheel advances one to more steps to quickly advance, for example: 1 to Three grades are used to quickly enter the gear. If there are too many gears, you can use the gearshift lever to complete the multi-step gear. For example: 1 to 3 grades to quickly reverse the gear. If there is too much gear, you can dial the ticket. The reverse lever is used to retreat to the first gear, and the invention has the functions of fast forward, reverse, and single return .

The utility model relates to a shifting handle comprising: a brake grip body, a brake handle and a ratchet gear shifting mechanism; a brake handle is pivoted on a side of the brake grip body, and an alcove is arranged on the bottom side for the ratchet gear shifting mechanism to be worn; The inner side of the main body is provided with an alcove and two lugs, and the concave chamber can accommodate the ratchet gear shifting mechanism, and the main shaft of the ratchet tooth shifting mechanism is used to pierce the perforation of the side shaft of the alcove, and then the main shaft screw is used to extend from the alcove to the side.

After the pulling wire teeth (71) are driven, the positioning teeth (70), the pushing wire teeth (65) and the shifting wire seat (74) will synchronously roll counterclockwise, and the shifting wire base (74) will pull the counterclockwise and then pull the shifting gear. After the cable (91) is connected to the transmission, the rear derailleur is displaced to achieve a 1 to 3 shift. When the positioning tooth (90) is rolled counterclockwise to stop scrolling, the hook (691) on the positioning hook (69) will Scaling along the ratchet teeth (702) of the positioning teeth (70), when the retracting lever (72) returns to the original position, the positioning hook (69) is barbed (691) and then the positioning teeth (70) are hooked. The ratchet (702) causes the positioning tooth (70) to be unable to rotate, causing the ratchet gear shifting mechanism (60) to return to a stationary, unrolled state.
