Description
Technical field
The utility model relates to a kind of nuts, more particularly to one kind can quickly judge nut and the fastening shape by securing objects
The nut of state.
Background technique
Nut is a kind of common fastener, is connect by its internal screw thread with by the external screw thread of securing objects, is provided good
Leakproofness, in addition it has many advantages, such as the standard component that installation and removal are convenient, are easily processed into various materials and reusable,
Thus it is widely used.But existing nut is not easy to judge with by the tightening state of securing objects.If nut not with fastened
Object fastening is complete, and operator fails to accurately identify, and may cause leakage.In fastening nut, operator is with feeling
Judge nut and whether fastened completely by securing objects, also easily determines error.In order to ensure nut is fastened with by securing objects
Thoroughly, operator's usually rotating screw cap always, the terminal end surface until nut contacts with the surface by securing objects, Bu Nengzai
When rotating screw cap, just stop operating nut, thus will appear nut and fastens excessive problem, to cause nut and be fastened
The accelerated wear test of the screw thread of object, nut and can not be tightened again by fastener, and the stripped thread being just known as causes under leakproofness
Drop, leads to nut and is substantially shortened by the securing objects service life.
Accordingly, it is desirable to provide a kind of nut, itself and asking by the tightening state of securing objects must not quickly be judged by carrying out solution
Topic.
Summary of the invention
To solve the above problems, the utility model provides a kind of nut, the nut can quickly judge its with by fastener
The tightening state of body.
Nut provided by the utility model comprising main body and be located at the body ends, formed with the main body
One indicating ring of one；
The main body is cylindrical shape comprising screw thread, stress surface, through-hole and multiple fins；
The screw thread is located at the inner surface of the main body；
The stress surface is located at the body interior, one end opposite with the indicating ring；
The through-hole is circle, positioned at one end identical with the stress surface, is used for across by securing objects；
Multiple fins are located at the outer surface of the main body, can play the role of in fastening nut it is anti-skidding, just
In fastening and disassembling section.
The indicating ring is located at the end of the main body, forms one with the main body, the indicating ring tool
There are multiple recess portions, the instruction for slightly protruding the terminal end surface of the indicating ring is respectively provided at the center of multiple recess portions
The terminal of item, the bar has contact surface.
The number of the recess portion and the bar is at least 4.
Preferably, the number of the recess portion and the bar is 4.
When the contact surface of multiple bars with by the surface of securing objects there are when gap, show nut not with
Completely by securing objects fastening, operator is prompted to need to continue fastening nut.When nut is with fastening complete by securing objects,
The contact surface of multiple bars is contacted by the surface of securing objects, at this point, if continuing fastening nut, the instruction
Item can occur bending and deformation, and swing in the space of the recess portion.After operator has found that bar starts bending deformation, and
When stop tightening operation, to prevent excessive fastening nut, be damaged to avoid nut and by the screw thread of securing objects, thus really
Protect good leakproofness.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the bottom view of nut provided by the utility model
Fig. 2 is the main view of nut provided by the utility model
Main view and section view constitutional diagram after the completion of Fig. 3 is nut provided by the utility model and is fastened by securing objects, wherein
In Fig. 1-3: 1- main body, 11- screw thread, 12- stress surface, 13- through-hole, 14- fin, 2- indicating ring, 21- recess portion, 22- bar,

Specific embodiment
In order to make those skilled in the art better understand the technical solution of the utility model, 1-3 with reference to the accompanying drawing
The utility model is described in further detail with specific embodiment.
A kind of nut including main body 1 and is located at the end of main body 1, forms an integrated indicating ring 2 with main body 1.
Main body 1 includes screw thread 11, stress surface 12, through-hole 13 and fin 14, wherein
Screw thread 11 is located at the inner surface of main body 1；
Stress surface 12 is located inside main body 1, one end opposite with indicating ring 2, when fasten complete when, stress surface 12 with it is tight
Gu the end surface of object is in close contact；
Through-hole 13 is circle, is located at one end identical with stress surface 12, is used for across by securing objects；
Fin 14 is located at the outer surface of main body 1, fasten and dismantle nut when can play the role of it is anti-skidding, convenient for fastening
And disassembling section；
Preferably, fin 14 be specially 1 equal length of 8 length and main body long rib 14 and between long rib 14
16 short fins 14 for being shorter in length than 1 length of main body.
Indicating ring 2 is located at the end of main body 1, forms one with main body 1, and indicating ring 2 has multiple recess portions 21, multiple recess portions
A bar 22 is respectively provided at 21 center, the terminal of bar 22 has contact surface surface 23, and contact surface 23 protrudes from
The terminal end surface 24 of indicating ring 2, the length that contact surface 23 protrudes from the terminal end surface 24 of indicating ring 2 is 2 mm to 3 mm.
