Definitions

  • a bolt / nut loosening stopper comprises: an inner coil panel which fits into a screw groove formed in a leg of the bolt; And an outer coil spring that engages with a nut mounted on the bolt.
  • the inner coil spring it is sufficient for the inner coil spring to be able to suppress the loosening of the net, and it is not always necessary to rotate the leg of the bolt when it is turned clockwise as shown by the symbol B in FIG.
  • the winding direction of the upper coil panel is determined by the direction in which the thread groove of the bolt is formed, and is necessarily limited to the winding direction shown in FIG. Of course, this is not the case.
  • the outer coil panel it is sufficient for the outer coil panel to be able to suppress the loosening of the nut by always applying a torque to the nut in the fastening direction, and it is not always necessary.
  • the tip of the outer coil panel is formed in a hexagonal shape is to firmly engage with the nut 7 and prevent further loosening of the nut. Also, the tip of the outer coil panel does not need to be formed in a hexagonal shape. In other words, any shape may be used as long as the engagement with the nut can be strengthened.
  • the inner coil panel 2 is screwed to the leg 8 of the bolt to which the tip 4 of the nut 4 is screwed. Attach until the tip 5 comes into contact with the nut 7 and does not advance any further.
  • the inner coil panel is fitted so as to fill the screw groove, and the elastic force of the inner coil panel prevents the bolt from being loosened.
  • the inner coil spring is pressed down against the center of the axis of the leg 8, and the contact between the inner coil panel and the thread groove is pressed to generate a strong frictional force. It is fixed in the thread groove of the bolt leg.
  • the size of the torque provided by the outer coil is determined by how much the tip of the outer coil is turned back in the direction opposite to the winding direction of the outer coil. is there.
  • the bolt / nut loosening stopper to which the present invention is applied is entirely composed of one elastic material, the manufacture thereof is simple, and furthermore, the inner coil is preliminarily manufactured.
  • the inner diameter of the lupine is adjusted to the outer diameter of the bolt to be fitted, and the outer coil panel is manufactured according to the size of the nut to be engaged. Therefore, it is extremely easy to use the inner coil spring by screwing it into the leg of the bolt and then twisting the base end of the outer coil spring to some extent. Can be done.
