Cylindrical lock adjusting steel bolt mechanism

DING FAN / YAO CHUNLIANG / HU WEILI

The invention relates to an adjusting steel bolt mechanism for a cylindrical lock, which is designed for solving the technical problems of inconvenience in production, assembly, use and adjustment, high cost and small application range of the existing like products. The steel bolt adjusting mechanism is characterized in that a rotating shaft is arranged in a base of the steel bolt adjusting mechanism, one end of the rotating shaft extends out of the bottom of the base and is connected with one end of a locking screw extending out of a sleeve, an opening is formed in the end corner of the top of one side of the sleeve, a steel bolt threaded hole is formed in one end of a steel bolt, and the other end of the steel bolt extends out of the opening of the sleeve; an external thread section at one end of the adjusting screw is connected with a steel bolt threaded hole of the steel bolt, the adjusting screw and the steel bolt are connected into a whole, the locking screw is arranged in a center hole of the adjusting screw, the steel bolt and the adjusting screw are arranged on the sleeve through the locking screw, and an outer hexagon is arranged on the outer diameter of the end of the adjusting screw. The end plane of the adjusting screw is larger than the diameter of a top orifice of the sleeve, and the steel bolt extending out of the sleeve is limited in an opening of the sleeve and moves up and down through rotation of the adjusting screw.

本发明涉及一种圆柱锁具调节钢栓机构，是针对解决现有同类产品的生产装配和使用调节较为不便，成本较高，应用范围较小的技术问题而设计。其要点该调节钢栓机构的基座内设有转轴，转轴的一端伸出基座的底部，转轴该端与套筒内伸出的锁紧螺钉一端连接，套筒的一侧顶部端角处设有开口，钢栓的一端设有钢栓螺纹孔，钢栓的另一端伸出套筒的开口，调节螺钉一端的外螺纹段与钢栓的钢栓螺纹孔连接，调节螺钉与钢栓连为一体，锁紧螺钉设置于调节螺钉的中心孔内，钢栓、调节螺钉通过锁紧螺钉设置于套筒，调节螺钉的端头外径设有外六角，调节螺钉的端头平面大于套筒的顶部孔口直径，伸出套筒的钢栓限位于套筒的开口内，钢栓通过调节螺钉转动而上下移动。
