Nut for locking operation
2015
The invention discloses a nut for locking operation. The nut comprises a flange and a bolt matched with the flange. The bolt is sleeved with a circular nut body. Small threaded holes are evenly distributed on the periphery of a threaded hole of the circular nut body. Screws are installed in the small threaded holes. A spanner rotation hole is formed in the outer wall of the circular nut body in the radial direction. The nut is simple in structure and convenient to operate; and the requirement for the pre-tightening force can be met only through a small-torque spanner, and meanwhile equipment overhaul time can be greatly shortened.
