Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of nut, especially a twelve-angle locking antitheft nut's technical field.
[ background of the invention ]
The hexagonal nut (Hexagon nut) is matched with the bolt and the screw to be used for connecting and fastening the machine parts. According to different materials, the materials are classified into carbon steel, stainless steel, non-ferrous metals (such as copper) and the like. The working principle of the hexagon nut is that the friction force between the hexagon nut and the bolt is adopted for self-locking. The existing hexagonal nut has no anti-loose and anti-theft effect, and is easy to loosen and disassemble. The hexagonal nuts on the iron tower and the fan are stolen, which is a great risk and easy to collapse.
[ Utility model ] content
The utility model aims at solving the problem among the prior art, provide a dodecagonal locking antitheft nut, can make the outside shape of nut change into the dodecagonal and reach the theftproof effect, do not have the specialized tool can't dismantle, the bottom changes the shape of flange into simultaneously and reaches locking effect.
In order to achieve the purpose, the utility model provides a twelve-angle locking antitheft nut, including nut body, screw hole, vertical bead, locking flange dish and arc-shaped surface, the inside axial of nut body is run through and is provided with the screw hole, the lateral surface of nut body encircles and is provided with twelve vertical beads, vertical bead and nut body formula structure as an organic whole, the bottom of nut body is provided with locking flange dish, the arc-shaped surface that the side shape of locking flange dish is the top and shrinks gradually.
Preferably, the vertical convex edges are symmetrically distributed on the outer side surface of the nut body in pairs, and the cross sections of the vertical convex edges are triangular.
Preferably, the outer side surfaces of the vertical convex ribs are sprayed with a frosted coating.
Preferably, the lower part of the vertical rib is provided with an anti-theft card, and the anti-theft card is in the shape of a right triangle.
Preferably, the number of the anti-theft cards is multiple, the anti-theft cards are uniformly distributed on the outer side of the vertical side face in a surrounding mode, and the height of each anti-theft card is two thirds of the height of the vertical rib.
Preferably, the locking flange and the nut body are of an integrated structure.
Preferably, the bottom of the anti-loosening flange plate is uniformly provided with arc-shaped concave-convex grains in a surrounding mode.
