Embodiment Construction

[0028] see Figure 1 to Figure 6 , a bicycle operating mechanism of the present invention, comprising a base housing 1, a ratchet assembly 2 rotatably installed in the base housing 1 and resettable, sliding between a first position and a second position to control the ratchet assembly 2. The ratchet hook member 3 that rotates clockwise or stops rotating and the lever assembly 4 used to drive the ratchet hook member 3 to move, and also includes the ratchet member 5 and the gear assembly 6 used to drive the ratchet wheel assembly 2 to rotate clockwise. It is convenient to distinguish the direction of rotation. In this application, the attached Figure 1 to Figure 5 In the figure, the direction I is counterclockwise, and the direction II is clockwise. The ratchet member 5 is rotatably mounted on one side of the gear shift assembly 6 , and the ratchet member 5 includes a toothed portion 51 capable of engaging with the ratchet assembly 2 and a swing portion 52 abutting against the...

Abstract

The invention discloses a bicycle operation mechanism which comprises a base shell, a ratchet wheel assembly rotationally installed in the base shell and capable of being reset, a ratchet hook component sliding between a first position and a second position so as to make the ratchet wheel assembly rotating anticlockwise or stop rotating, and a shifting rod assembly used for driving the ratchet hook component. The bicycle operation mechanism further comprises a pawl component and a gear advancing assembly used for driving the ratchet wheel assembly to rotate clockwise. The pawl component is installed on one side of the gear advancing assembly in a swing mode and comprises a toothed part capable of being engaged with the ratchet wheel assembly and a swing part abutting against the pawl component. The ratchet hook component pushes the swing part, so that the toothed part is forced to be engaged with the ratchet wheel assembly, the toothed part is controlled by the gear advancing assemblyto be disengaged from the ratchet wheel assembly, no matter the ratchet wheel assembly rotates forwards or backwards, the gear advancing assembly and the shifting rod assembly can control the pawl component to act, the idle stroke of the pawl component is reduced, and the whole control procedure is smooth without being blocked.

Description

technical field [0001] The invention relates to the technical field of shifters, in particular to an operating mechanism. Background technique [0002] An existing bicycle shifter includes a base housing, and a fixing seat, a ratchet member, a ratchet hook member, a ratchet member, a shift lever assembly and a shift assembly are arranged in the base housing. The ratchet member can rotate in the base shell, and the ratchet hook member has a stop pawl and an interception pawl oppositely arranged on it. The gear positioning is maintained and the reverse gear is maintained. The ratchet hook member is driven by the lever assembly, and the lever assembly is connected in the base shell through a turning point. When the lever assembly swings with the turning point as the swing origin, and the lever assembly swings in the first direction or in the second direction Finally, the driving lever assembly can abut against the ratchet hook member, and then push or pull the ratchet hook me...
