Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Embodiment one
To shown in Figure 6, a kind of lock nut pad comprises pad as Fig. 1, and described pad offers perforation, and described pad comprises Upper gasket 1 and lower levelling plate 2, described Upper gasket 1 and lower levelling plate 2 riveted joints.
Present embodiment adopts two-part structure with pad, be divided into Upper gasket 1 and lower levelling plate 2, the lower levelling plate 2 that contacts with attachment face is made by steel material or the higher metallic material of other hardness, the Upper gasket 1 available iron material or other metallic material that contact with lower levelling plate 2 are made, and actual adding can be easy to produce man-hour, and increased and attachment face between contact force, be not easy wearing and tearing, both effectively play locking effect, saved manufacture cost again, improved profit.
In the present embodiment, described Upper gasket 1 bottom is provided with riveting column 11, and lower levelling plate 2 offers the riveted holes 21 for riveting column 11 riveteds, riveting column 11 is passed riveted holes 21 back riveteds, thereby Upper gasket 1 and lower levelling plate 2 are closely linked together.
In the present embodiment, the annulus of described Upper gasket 1 for being made by iron material, Upper gasket available iron material or other metallic material are made.
In the present embodiment, the annulus of described lower levelling plate 2 for being made by the steel material, lower levelling plate 2 for increase and attachment face between contact force, so need steel material or the higher metallic material of other hardness after Overheating Treatment make.
In the present embodiment, the upper surface of described Upper gasket 1 is provided with a plurality of wedge-shaped catch 12, described wedge-shaped catch 12 is along the upper surface annular array of Upper gasket 1, the bottom of nut also offers the inclined-plane that matches with wedge-shaped catch 12, adopt the wedge-shaped catch 12 of this structure, when pad was motionless, nut only can unidirectionally rotate, and only can be more stubborn more tight, thereby realize anti-loosing effect.
