[ detailed description ] embodiments
Referring to fig. 1, 2 and 3, the invention relates to a non-metal insert locknut, which comprises a nut body 1, a first non-metal insert 2 and a second non-metal insert 3, wherein a threaded hole 11 and a coaxial counter bore 12 communicated with the threaded hole 11 are arranged in the nut body 1 along an axial direction, a first annular groove 13 facing away from the axial direction is arranged at the bottom end of the counter bore 12, a first annular bulge 21 is arranged at one side of the first non-metal insert 2, which is arranged in the counter bore 12 and close to the bottom surface of the counter bore 12, the thickness of the first annular bulge 21 is not less than the width of the first annular groove 13, a second annular groove 16 is also arranged on the nut body 1 and is at the same side with the counter bore 12, the second non-metal insert 3 is fixed in the second annular groove 16, and the top surfaces of the first non-metal insert 2 and the second non-metal insert 3 are higher than, the aperture of counter bore 12 is greater than the aperture of screw hole 11, the internal diameter of first non-metal insert 2 is less than the aperture of screw hole 11, the body outside of first non-metal insert 2 is equipped with third ring channel 22, the junction of the protruding 21 of first annular with the body of first non-metal insert 2 is close to the position of third ring channel 22, the tail end of first ring channel 13 is equipped with fourth ring channel 14 towards the top surface direction of counter bore 12, the width of fourth ring channel 14 is unanimous with the width of first ring channel 13, one side of fourth ring channel 14 still is equipped with second annular bulge 15, first non-metal insert 2 and the non-metal insert 3 of second are the nylon inserts.
