Abstract
The invention provides a locking nut, which has the advantages of simple structure, convenience in adjustment and capability of greatly improving the reliability of a fastener. The locking nut comprises a nut body, wherein the nut body is in a circular structure; and four rectangular notches are arranged on the outer circumference of the nut body.
Description
Technical field
The present invention relates to the engineering nut, be specially locking nut.
Background technique
In some installations and facilities, often need to carry out fastening to component, in general be to adopt the frictional force between the nuts and bolt to carry out self-locking, but the reliability that this self-locking in the such mechanical shock of similar vibrations externally occurs will reduce, will become flexible between the nuts and bolt, will take some locking measures in some important occasions so, guarantee the reliability of nut check, locking nut is exactly a kind of locking measure wherein, former locking nut adopts flat square structure, and flat square chi is very little larger, it is adjusted the pipe wrench that needs with large model at every turn and carry out dismounting, pipe wrench is heavier, gets at every turn, also pipe wrench need expend larger muscle power, and also inconvenient with the pipe wrench dismounting.
Summary of the invention
For the problems referred to above, the invention provides locking nut, it is simple in structure, can conveniently regulate, and can greatly improve the reliability of fastening piece.
Its technological scheme is such: it comprises nut body, it is characterized in that: described nut body adopts round structure, and the excircle of described nut body is provided with rectangular notch.
It is further characterized in that: described rectangular notch is provided with four.
The invention has the beneficial effects as follows, the excircle of nut body is provided with rectangular notch, when then needing to adjust, can utilize hook spanner chucking rectangular notch to screw the dismounting of finishing nut body, and is more flexible.
