In order to achieve the above purpose, the utility model provides an anti-theft lock nut, which comprises a cylindrical inner nut, a threaded hole, anti-skid convex strips, an outer hexagon nut sleeve and anti-skid grooves, wherein the threaded hole is penetrated and arranged in the cylindrical inner nut, a plurality of anti-skid convex strips are uniformly arranged on the upper end face and the lower end face of the cylindrical inner nut, a plurality of anti-skid convex strips are uniformly and axially distributed on the outer side face of the cylindrical inner nut, the outer hexagon nut sleeve is sleeved on the outer side face of the cylindrical inner nut, the outer hexagon nut sleeve and the cylindrical inner nut are connected in a detachable mode, and a plurality of anti-skid grooves which are matched with the anti-skid convex strips are uniformly arranged on the inner side face of the outer hexagon nut sleeve.
Preferably, the outer hexagon nut sleeve comprises two piece sleeve blocks, a rotary pin shaft and adsorption magnet blocks, one sides of the two piece sleeve blocks are movably connected through the rotary pin shaft, the adsorption magnet blocks are embedded in one sides of the piece sleeve blocks, and the adjacent piece sleeve blocks are adsorbed together through the adsorption magnet blocks.
Preferably, the cross section of the anti-slip bead is arc-shaped, and the anti-slip bead and the cylindrical inner nut are of an integrated structure.
Preferably, the anti-slip raised strips are arc raised strips, the thickness of the anti-slip raised strips is gradually increased from the inner side to the outer side, and the anti-slip raised strips are uniformly and radially arranged on the upper end surface and the lower end surface of the cylindrical inner nut.
Preferably, the inner side surface of the outer hexagonal nut sleeve is matched with the outer side surface of the cylindrical inner nut.
Preferably, smooth guide flaring is arranged at the opening positions of the two ends of the threaded hole.
The utility model has the beneficial effects that: according to the utility model, the cylindrical inner nut, the threaded hole, the anti-slip convex strips, the outer hexagonal nut sleeve and the anti-slip grooves are combined together, and through experimental optimization, the outer hexagonal nut sleeve which is detachably arranged outside is matched with the cylindrical inner nut to prevent the nut from being detached by a tool, and meanwhile, the anti-slip convex strips which are uniformly arranged on two end surfaces of the cylindrical inner nut are matched for limiting and stopping, so that the anti-theft performance of the nut is obviously improved, and the market popularization is facilitated.
The features and advantages of the present utility model will be described in detail by way of example with reference to the accompanying drawings.
