Shape guide surface, arcuate guide surface and outside cell wall are arranged in angle.Tail portion of nylon ring itself be it is tubular, in annular groove
Notch setting arcuate guide surface facilitate tail portion arcuately guide surface enter in annular groove.
In above-mentioned self-locking nut, the angle between the arcuate guide surface and outside cell wall is 120 ° -170 °.
Angle in above-mentioned self-locking nut, between the inside cell wall and pyramid type boss top surface of the annular groove
It is 30 ° -60 °.
Compared with prior art, the utility model has the following beneficial effects:
The application is embedded with the self-locking nut of nylon ring using main nut and secondary nut composition, and main nut and secondary nut pass through
The pyramid type boss and pyramid type groove matched is interconnected and fixed, and wherein nylon ring is inlaid in pyramid type groove slot bottom
Caulking groove in, the flaring structure of pyramid type groove, which for nylon ring to be embedded in caulking groove, becomes more convenient quick, and pyramid type
Boss is while holding out against nylon ring, in the tail portion insertion annular groove of nylon ring, pyramid type boss top surface and annular groove
Dual positioning is realized to nylon ring, prevents nylon ring from spinning, the through-hole of nylon circle center is passed through convenient for bolt.
