through above-mentioned technical scheme, effectual back of screwing up at round nut can realize locking the location to round nut.

Further, the through hole is equal to the diameter of the threaded hole;

through the technical scheme, the round nut and the bolt are matched favorably, so that the round nut and the bolt are better sleeved together.

Furthermore, the four outer positioning lugs are respectively matched with the grooves, and the width of each outer positioning lug is equal to that of each groove;

through the technical scheme, the nut is matched with the gasket, and the positioning work of the gasket on the round nut is realized.

Furthermore, the inner positioning lug is positioned in the limiting groove, and the width of the inner positioning lug is equal to that of the limiting groove;

through the technical scheme, the movement of the gasket is effectively limited, and the locking work of the round nut is realized.

Further, the gasket is integrally formed by punching a steel plate;

through above-mentioned technical scheme, improve the security, prevent that the gasket from receiving the damage in the use.

Further, the thickness of the gasket is 1.5-2.0 mm;

through above-mentioned technical scheme, the space of bolt can not too much be occupied to lower thickness.

Further, the outer positioning lugs are uniformly arranged on the outer side wall of the gasket;

through above-mentioned technical scheme, better with outer location ear card in the recess of round nut, realize locking location.

The utility model discloses following beneficial effect has:

1. the utility model discloses in, set up mobilizable outer location ear, can effectual realization to the location of round nut, fail safe nature is high.

2. The utility model discloses in, through the linkage of outer location ear and interior location ear, the spacing of location ear in utilizing makes the round nut locked after screwing up.
