The invention relates to the technical field of bicycles, in particular to a bicycle handlebar turning locking structure which comprises a supporting mechanism, wheels are rotatably mounted at the two ends of the bottom of the supporting mechanism, plastic wheels are symmetrically and fixedly mounted on the wheel at the front end of the supporting mechanism, and the supporting mechanism comprises a positioning component and a limiting component. The positioning part is rotatably mounted in the front end of the limiting part and comprises alignment devices and a steering device, the alignment devices are symmetrically and fixedly mounted at the bottom end of the steering device, and each alignment device comprises a positioning shaft rod, a guide rod, a matching clamping plate, a first spring, a supporting cavity and a first extension rod; the positioning shaft rod is fixedly mounted at the top end of the left side of the first extension rod, the guide rod is fixedly mounted on the left side of the first extension rod, the first extension rod is fixedly mounted at the bottom of the side end, close to the guide rod, of the matching clamping plate, and the matching clamping plate is slidably inserted into the supporting cavity. And through the arrangement of the supporting mechanism, the purposes of turning wheel locking and precise alignment lubrication of the bicycle are achieved.

    本发明涉及自行车技术领域,具体的说是一种自行车把手变向锁固结构,包括支撑机构,支撑机构的底部两端转动安装有车轮,且支撑机构前端的车轮上对称固定安装有塑胶轮,支撑机构包括定位部件和限制部件,定位部件转动安装在限制部件的前端内部,定位部件包括对位装置和转向装置,对位装置对称固定安装在转向装置的底端,对位装置包括定位轴杆、导向杆、配合卡板、第一弹簧、支撑腔体和第一延伸杆,定位轴杆固定安装在第一延伸杆的左侧顶端,导向杆固定安装在第一延伸杆的左侧上,第一延伸杆固定安装在配合卡板靠近导向杆的侧端底部,配合卡板滑动插接在支撑腔体的内部。通过支撑机构的设置,实现了自行车进行变向式轮锁与精准式对位润滑的目的。
