Detailed Description
The present invention is described in detail below with reference to the accompanying drawings, and as shown in fig. 1-6, the present invention comprises a connecting carcass 1, a gasket 2, a bolt 3, and a mounting carcass 4; the connecting carcass 1 is connected with the mounting carcass through four bolts 3:
the connecting tire body 1 comprises a fixing part 9 at the lower end, and a handle 8 is fixed on the upper surface of the fixing part; the cross section of the handle 8 is rectangular, four through holes 10 are symmetrically arranged on two sides of the handle 8, and two ends of the fixing part corresponding to the other two sides of the handle are provided with notches 7;
the mounting tire body 1 comprises a rectangular through hole 12 in the middle, notches 6 are arranged at four corners of the rectangular through hole 12, and threaded holes 13 corresponding to the through holes 10 of the fixing part are arranged at two ends of the rectangular through hole; two threaded through holes 11 are arranged on the side surface where the tire body 1 is installed, and the threaded through holes 11 are communicated with a rectangular through hole 12;
the connecting carcass 1 is connected with a mounting carcass 4 through a bolt 3;
the permanent magnet 5 is inserted into the rectangular through hole 12, one side of the permanent magnet 5 is abutted with one side of the rectangular through hole 12, the other side of the permanent magnet 5 is abutted with the gasket 2, and the gasket 2 is abutted with the bolt 3 arranged in the threaded through hole 11;
the notch 6 corresponds to the notch 7 of the rectangular through hole in position, so that whether the position of the permanent magnet in the rectangular through hole is correct or not can be conveniently observed from the upper part, and the permanent magnet can be adjusted through the thin rod. The notch 7 is in the shape of a circular arc extending towards the outer side of the rectangular through hole.
As shown in fig. 7, in order to prevent the gasket from falling out of the rectangular through hole and injuring a workpiece or an operator due to the fact that the bolt is not tightly pressed during operation, a groove 14 is formed in the inner side, close to the bolt through hole, of the rectangular through hole, and the gasket 2 is arranged in the groove, so that the gasket can be conveniently adjusted, and the gasket can be prevented from falling out of the lower portion of the rectangular through hole (the gap between the rectangular through hole and the permanent magnet is smaller than the thickness of the gasket).
The tire body is mounted only by fixing one end of the permanent magnet, so that an operator can assemble the permanent magnet conveniently.
All parts are made of brass, so that the mounting tire is prevented from being attracted to the permanent magnet to interfere with assembly.
The bolt is propped against the gasket by mounting the tire body, and the permanent magnet is clamped by screwing the bolt; to prevent crushing damage to the permanent magnet when the bolt is tightened.
