The invention discloses an improved bicycle handlebar stem locking structure, and relates to the field of bicycle accessories. The improved bicycle handlebar stem locking structure comprises a handlebar stem core gland and a handlebar stem core tube which are arranged outside a long rod screw, and a reinforcing piece is also arranged between the handlebar stem core gland and the handlebar stem core tube; the reinforcing piece is used for making contact with the opposite end faces of the handlebar stem core gland and making contact with the opposite end faces of the handlebar stem core tube respectively, the reinforcing piece is in threaded connection with the long rod screw, and wedge-shaped faces matched with the corresponding end faces of the handlebar stem core gland in an abutting modeare integrally formed on the upper end faces of the reinforcing pieces; and a wedge-shaped surface which is propped against and matched with the corresponding end surface of the handlebar stem core is also integrally formed on the lower end surface of the reinforcing piece. The handlebar stem core and the reinforcing piece can be tensioned at the same time through the long-rod screw, and therefore bidirectional dislocation of the handlebar stem core gland, the handlebar stem core tube and the reinforcing piece is achieved at the same time, the locking contact face is increased, and the locking strength is improved.

    本发明公开了一种改进型自行车把立锁紧结构,涉及自行车配件领域,包括设置在长杆螺丝外部的把立芯压盖与把立芯管,所述把立芯压盖与把立芯管之间还设置有一个当长杆螺丝在拉紧后,用于分别与把立芯压盖相对端面之间和与把立芯管相对端面之间均接触的加固件,且加固件螺纹连接于长杆螺丝上,加固件的上端面一体成型有与把立芯压盖对应端面相抵触配合的楔形面,而加固件的下端面也一体成型有与把立芯管对应端面相抵触配合的楔形面。本申请能够通过长杆螺丝同时拉紧把把立芯管与加固件,进而同时达到把立芯压盖、把立芯管与加固件的双向错位,增加锁紧接触面,提高锁紧强度。
