A vertical pipe locking device is characterized in that a tensioning block is arranged in a front fork vertical pipe, an end cover is arranged at one end, outside the front fork vertical pipe, of a handle vertical pipe, and a pull rod penetrates through the end cover and is in threaded connection with the tensioning block; the other end of the pull rod is provided with a limiting mechanism which interacts with the end cover and exerts acting force on the tensioning block. The limiting mechanism can be a quick release assembly and can be quickly locked or unlocked through a handle; the limiting mechanism can also be a protrusion arranged on the pull rod and located on the inner side of the end cover hole, so that limiting is formed when the pull rod rotates outwards, rotation of the pull rod screw is changed into thrust to the tensioning block, and therefore the tensioning block is separated from the handle vertical pipe, and unlocking is achieved. By using the handlebar stem locking device, the operation convenience of adjusting the handlebar stem can be greatly improved, all parts cannot be damaged, the service life of a vehicle is greatly prolonged, and the safety of the vehicle is greatly improved.

    一种立管锁紧装置,在前叉立管内设置涨紧块,在把竖管位于前叉立管外的一端设置端盖,拉杆穿过端盖与涨紧块螺接;拉杆的另一端设置有与端盖相互作用并对涨紧块施加作用力的限位机构。该限位机构可以是快拆组件,通过手柄快速进行锁紧或解锁;限位机构也可以是设置于拉杆上位于端盖孔内侧的凸起物,使得拉杆向外旋动时形成限位,使拉杆螺丝的转动变为对涨紧块的推力,从而将涨紧块与把竖管分离,实现解锁。通过该把立管锁紧装置的使用,可以极大地提高把竖管调节的操作方便性,且不会对各零部件造成损伤,极大地提高了车辆的使用寿命和安全性。
