    • A free-running-on, locking-off and tension directly indicated locking nut, capable of indicating whether the locking nut is suitably tightened with the required axial tension and preventing the locking nut from becoming loose, includes a body portion formed with a base and a conical seat portion extending upwardly from a central portion of a top of the base, the seat portion having an upper end formed with a vertical outer wall surface, the body portion having an axial hole extending through the body portion and provided with internal threads, and a cap having an axial through taper hole which is smaller than the concial seat portion in height. The axial through taper hole is formed with a conical surface with a large diameter at a bottom thereof, a neck with a vertical surface extending upwardly from a top of the conical surface, and a chamfer extending upwardly outwardly from a top of the neck to form a countersink, the conical surface being configured to fit over the conical seat portion. The locking nut can engage a bolt at zero loading resistance, automatically produce loose resistant torque when fastened on a workpiece, and indicate whether the locking nut is fastened with the required axial tension by showing the change in the clearance between the body portion and the cap.
    • 一种自由运行的锁定和张力直接指示的锁定螺母,能够指示锁定螺母是否适当地紧固所需的轴向张力并防止锁定螺母松动,包括形成有基部的主体部分 从所述基座的顶部的中心部分向上延伸的锥形座部分,所述座部分具有形成有垂直外壁表面的上端,所述主体部分具有延伸穿过所述主体部分并设有内螺纹的轴向孔, 以及具有小于高度的座椅部分的轴向贯通锥形孔的盖。 轴向通过锥形孔形成有在其底部具有大直径的锥形表面,具有从锥形表面的顶部向上延伸的垂直表面的颈部和从颈部的顶部向上向外延伸的倒角以形成 一个埋头孔,锥形表面被配置成装配在锥形座部分上。 锁定螺母可以以零负载阻力接合螺栓,当紧固在工件上时自动产生松散的扭矩,并且通过显示主体部分和盖子之间的间隙的变化来指示锁定螺母是否以所需的轴向张力紧固 。
