Wherein: the device comprises 1-concave gaskets, 2-convex gaskets, 3-bolts, 4-nuts, 5-bottom plates, 6-mounting holes, 7-hemispherical grooves, 8-magnetic blocks, 9-fixed parts, 10-mounting surfaces, 11-attaching surfaces, 21-extruding surfaces and 22-hemispherical surfaces.

Detailed Description

The utility model will be further described with reference to specific embodiments shown in the drawings.

Referring to fig. 1-3, the utility model relates to a random direction gasket, which comprises a concave gasket 1 and a convex gasket 2 which are arranged in a split mode, one side of the convex gasket 2 is a hemispherical surface 22, the other side of the convex gasket is an extrusion plane 21, one side of the concave gasket 1 is provided with a hemispherical groove 7 matched with the hemispherical surface 22 of the convex gasket 2, the other side of the concave gasket 1 is a joint plane 11, the convex gasket 2 is arranged in the hemispherical groove 7 through the hemispherical surface 22, the middle positions of the concave gasket 1 and the convex gasket 2 are both provided with mounting holes 6 for mounting bolts 3, the mounting holes 6 on the concave gasket 1 are communicated with the hemispherical groove 7, when the bolts 3 are not perpendicular to the mounting surface 10 of a fixed piece 9, the concave gasket 1 is firstly mounted into the bolts 3, the joint plane 11 of the concave gasket 1 is jointed with the mounting surface 10 of the fixed piece 9, then the convex gasket 2 is mounted into the bolts 3, the hemispherical surface 22 of the convex gasket 2 and the hemispherical groove 7 of the concave gasket 1 are mutually embedded and assembled, finally, the nut 4 is screwed in, the laminating plane 11 of the concave gasket 1 and the extruding plane 21 of the convex gasket 2 can be fully laminated with the mounting surface 10 and the nut 4 respectively by rotating the hemispherical surface 22 of the convex gasket 2, all contact positions are guaranteed to be in surface contact, the reliability of spiral compression is improved, the nut 4 is not easy to loosen after tensioning, and the connection stability is improved.

Specifically, the diameter of the mounting hole 6 on the convex gasket 2 is larger than that of the mounting hole 6 on the concave gasket 1, so that the convex gasket 2 can rotate at the concave gasket 1, and the plane of the concave gasket 1 and the plane of the convex gasket 2 can be always fully attached to the mounting surface 10 and the nut 4.
