Preferably, the corrosion protection structure comprises: the protection plate, the top fixed connection of bolt and protection plate, half annular has been seted up on the surface of nut, when with bolt screw in nut, the protection plate also can descend along with the decline of bolt, just so can block the screw thread on petroleum contact bolt and the bolt to prevented that they from being corroded, just so be difficult to cause not hard up.
Preferably, a hole is formed in the top of the nut.
Preferably, a cavity is formed in the fastening block.
Preferably, the fastening block is penetrated by a T-bar.
Preferably, the top of the bolt is provided with a cross-shaped groove.
Compared with the prior art, the utility model provides the locknut for petrochemical industry, which has the following beneficial effects:
1. this locknut for petrochemical industry through setting up fixed knot structure, is screwed into the nut with the bolt after, pushes down the fastening piece downwards, at this moment because the surface of fastening piece is certain slope angle with the place of bolt inner wall contact, at this moment because friction and the reason that produces lifting tension just can not loosen between bolt and the nut, at this moment even the oil oozes between nut and the bolt also can not produce looseness.
2. This locknut for petrochemical industry through setting up anti-corrosion structure, when screwing in the nut with the bolt, the guard plate on bolt surface also can be through the recess on nut surface together downwardly moving, and the oil just can't touch the screw thread on nut and the bolt at this moment, just so can not cause the corruption to nut and bolt to the initiation has become flexible.
