In the figure, 1, a nut; 2. a stud; 3. a wear-resistant sleeve; 4. an insert block; 5. mounting grooves; 6. an elastic member; 7. a groove is embedded; 8. a wear layer; 9. an annular reinforcing rib; 10. a circular groove.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figure 1, the anti-rust wheel nut comprises a nut 1, wherein the nut 1 is provided with an internal thread and is connected with a stud 2 through thread fit, a wear-resistant sleeve 3 is arranged in the nut 1 and positioned between the nut 1 and the top of the stud 2, the outer peripheral wall of the wear-resistant sleeve 3 is provided with a plurality of embedded blocks 4 which are uniformly distributed in the circumferential direction and a plurality of mounting grooves 5 for the corresponding embedded blocks 4 to extend into, the rear end parts of the embedded blocks 4 extend into the corresponding mounting grooves 5 and are connected with the mounting grooves 5 through elastic pieces 6, one end of each elastic piece 6 is connected with the rear end part of each embedded block 4, the other end of each elastic piece 6 is fixedly connected with the inner end wall of each mounting groove 5, the elastic pieces 6 are fixedly connected with the rear end parts of the embedded blocks 4 and the inner end walls of the mounting grooves 5 in a welding manner, a plurality of embedded grooves 7 for the corresponding embedded blocks 4 are formed in positions, corresponding to the embedded blocks 4, on, when the wear-resisting cover 3 of installation, it leans on to offset abaculus 4 and 1 internal perisporium of nut, because the effect of elastic component 6, the abaculus 4 extrudees in to wear-resisting cover 3, when removing to embedded groove 7, in the embedded groove 7 is stretched out and stretch out to embedded block 4 outside, correspond embedded groove 7 and embedded block 4's position earlier before the wear-resisting cover 3 of installation, the bottom of nut 1 is provided with the annular strengthening rib 9 that supplies double-screw bolt 2 to pass, and also the cover is equipped with wearing layer 8 between the inner wall of this annular strengthening rib 9 and double-screw bolt 2.
