Referring to fig. 1, the embodiment of the present application discloses a connection mechanism using a bolt 1, including:
the bolt comprises a bolt 1, wherein the bolt 1 comprises a rod part 11 with an axis and a connecting part 12 arranged on the rod part 11, a flange part 13 is arranged at one end of the rod part 11, a step part 14 is arranged between the flange part 13 and the connecting part 12, and the cross section of the step part 14 perpendicular to the axis of the rod part 11 is not circular;
a first plate 2, wherein the first plate 2 is formed with a special-shaped hole 21, the section shapes of the special-shaped hole 21 and the step part 14 in the direction perpendicular to the axis of the rod part 11 are similar, the special-shaped hole 21 is larger than the step part 14, and the step part 14 can extend into the special-shaped hole 21 to deform so as to rivet the first plate 2 together with the flange part 13;

By means of the structure, the connecting mechanism can enable the step part 14 of the bolt 1 to deform through installing the die, so that the bolt 1 is riveted with the first plate 2 in the process that the bolt penetrates into the special-shaped hole 21 of the first plate 2, and then is connected with the second plate 3 through the connecting part 12. Since the caulking process is caused by the step portion 14, the bolt 1 can be applied to plate materials of various materials and hardnesses, particularly plate materials having a high hardness. Meanwhile, since the cross section of the stepped portion 14 is not circular, the stepped portion 14 still has high torsion resistance after the shape change.
Specifically, the first plate 2 may have a plate shape, and may be made of a metal material or other materials. The first sheet material 2 may be harder, for example, it may have a hardness of above 45HRC. The profiled hole 21 of the first sheet 2 is slightly arched in the direction of insertion of the bolt 1.
