Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, Figure 2, shown in Fig. 3 composition graphs 5 and Fig. 6, a kind of tamper-resistant union nut, comprises: union nut body 101, and described union nut body 101 offers the cylindrical structure of tapped blind hole 1011 for one end; Single direction rotation structure 102, is socketed in the outside of described union nut body 101; Auxiliary nut 103, is socketed in the outside of described single direction rotation structure 102; When applying screw-down torque at described auxiliary nut 103, described auxiliary nut 103 by described single direction rotation structure 102 to described union nut body 101 carry-over moment; When applying to unscrew moment at described auxiliary nut 103, described auxiliary nut 103 rotates around described union nut body 101.
In the present embodiment, consult Fig. 2, described auxiliary nut 103 is hollow structure, and its outer circumferential face is prismatic, is convenient to twisting.
In the present embodiment, consult Fig. 4, described single direction rotation structure 102 is unilateral bearing, its outer circumferential face is cylndrical surface, with the internal diameter interference fit of described auxiliary nut 103, both guarantees synchronous rotary, inner circumferential surface is provided with several roller bearings 1021, the shape of its rolling seat makes it can only roll to a direction, and can produce very large resistance and locked in the other directions.
In the present embodiment, consult Fig. 1, the closed end of described union nut body 101 is provided with the excessively pore 1012 through with described tapped blind hole 1011, and the described diameter crossing pore 1012 is less than the diameter of described tapped blind hole 1011.
