Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Embodiment one: as shown in Figure 1 to Figure 3, cambered surface flange nut, including nut body 2,2 side of nut body are tilted
Equipped with cambered surface flange I 3, nut body 2 and cambered surface flange I 3 are integrally formed, and the center of circle of the cambered surface flange I 3 is arranged far from spiral shell
The side of maternal body 2, I 3 bottom of cambered surface flange are equipped with inclined surface A5；The inclined surface A5 and angle a of horizontal direction is 1-8 °；A is small
When 1 °, screw rod with matching can be had damage when a is greater than 8 ° by not having anti-loose effect；Cambered surface flange I 3 is equipped with anti-
Slip teeth 4.
When the present embodiment is in use, it can be used cooperatively with plain bolt, as shown in Fig. 2, the work that the present embodiment is installed and used
Make principle are as follows:
Object to be fixed is covered on bolt, inclination cambered surface flange nut is then screwed in into bolt, tilts cambered surface flange spiral shell
When female stress is tightened, the B1 point pressure on cambered surface flange I 3 is greater than B2 point, continues to tighten, A1 point stress, and A1 point will be suffered
To power be transmitted at ipsilateral A2 point, formed laterally tightens power, make nut body 2 hold tightly bolt, increase the torque at A2 point
Frictional force；Due to the effect of power be it is mutual, 2 other side of nut body generates downward power, and is transmitted at A3 point, at this point,
A3 point is tightened torsional forces by not in the same direction, thus clamping screw.When continuing to tighten, due to being globoidal structure in the A5 of inclined surface,
Make at A3 point that there are gaps between object to be fixed, while under globoidal structure effect, the B1 point of I 3 two sides of cambered surface flange and
B2 point has rebounding characteristic, therefore, when high-intensitive Fatigue Vibration is with expanding with heat and contract with cold, can be subtracted under bounce effect
Vibration, so that inclination cambered surface flange nut be avoided to loosen or loosen.
When the present embodiment makes, the thickness of the side B1 is greater than the thickness of the side B2 in cambered surface flange I 3.
Embodiment two: the other side of the nut body 2 is equipped with nut 1；It is other to be the same as example 1.
