Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.

Example one

Referring to the accompanying drawings 1-4, the nut anti-loose structure provided by the utility model comprises a workpiece A1, a workpiece B2 and a main bolt 6, wherein the outer part of the main bolt 6 is in threaded connection with a nut B3 and a nut A4, the outer part of the main bolt 6 is movably provided with a spring pad 8, the outer part of a nut A4 is provided with an anti-loose mechanism, the anti-loose mechanism comprises a circular plate 5, the circular plate 5 is fixedly arranged on the outer part of a nut A4, connecting rods 11 are symmetrically arranged on the outer part of the circular plate 5, one ends of the two connecting rods 11, which are far away from the circular plate 5, are jointly connected with a circular plate 10, bolts 12 are movably arranged on the outer part of the circular plate 10, and transverse reinforcing bolts 13 are movably arranged on the outer part of the connecting rods 11.
