The bicycle variable speed controller comprises an upper fixing plate (1) and a lower fixing plate (2), and a winding roll (3) and a ratchet wheel (4) are arranged between the upper fixing plate (1) and the lower fixing plate (2). A push rod assembly (5) and a release rod assembly (6) are arranged below the lower fixing plate (2), a reset spring (7) is connected between the push rod assembly (5) and the release rod assembly (6), and a push block (8) for pushing the ratchet wheel (4) to rotate is connected to the push rod assembly (5). The device is characterized in that a shifting rod (9) is connected to the lower fixing plate (2), the shifting rod (9) can be pushed to move when the releasing rod assembly (6) rotates, and the pushing block (8) can be pushed to be separated from the ratchet wheel (4) after the shifting rod (9) moves. According to the gear shifting mechanism, clamping during gear retreating can be prevented, the gear shifting pushing stroke can be shortened, the gear shifting operation fatigue degree is relieved, parts are reduced, assembling is convenient, and the gear shifting mechanism has the advantages of being high in production efficiency and good in assembling stability.
本发明公开了一种即时进档的自行车变速控制器,它包括上固定板(1)和下固定板(2),上固定板(1)和下固定板(2)之间设置有卷线盘(3)和棘轮(4);下固定板(2)下方设置有推杆组件(5)和释放杆组件(6),推杆组件(5)和释放杆组件(6)之间连接有复位弹簧(7),推杆组件(5)上连接有推动棘轮(4)转动的推块(8);其特征在于:所述下固定板(2)上连接有拨杆(9),释放杆组件(6)转动时能够推动拨杆(9)移动,拨杆(9)移动后能够推动推块(8)与棘轮(4)脱离。本发明能够防止退档时卡住,还能够缩短进档推动行程、减轻进档操作疲劳程度、减少零件和方便组装,还具有生产效率高和组装稳定性好的优点。
