Description
[technical field]
The present invention relates to the technical field of fastener, the skill of especially a kind of high strength anti-loose nut with antiskid effect
Art field.
[background technique]
Nut is the fastener for having internal screw thread and being used cooperatively with bolt, has internal screw thread and with screw rod with the use of use
With passing movement or the machine components of power.Nut and bolt or screw rod are threaded together for tightening machine when use, are all
Manufacture it is mechanical must a kind of original part.
Current nut, since the groove on nut body is relatively smooth, after long-time use, antiskid effect drops significantly
Low, intensity is low, and stability is poor, when fastening to pressure vessel often due to vibration in the high voltage state and use of pressure vessel
It is dynamic, the case where will cause nut loosening and deform, it is not easy to firm clamp device, it is serious also to will cause safety problem.
[summary of the invention]
The object of the invention is to solve the problems of the prior art, a kind of high strength anti-loose with antiskid effect is proposed
Nut can be improved the non-skid property of nut body outer surface, prevent from loosening, and intensity is high, and stable type is good.
To achieve the above object, the invention proposes a kind of high strength anti-loose nut with antiskid effect, including nut
Ontology, the diameter at the middle part of the nut body are greater than the diameter of end, and the diameter of the nut body is from middle part to two
End is successively decreased, and the middle part of the nut body is run through equipped with threaded hole up and down, offers screw thread on the inner wall of the threaded hole,
Several anti-skid bulges are uniformly provided with along short transverse on the outer wall of the nut body, are equipped between the anti-skid bulge anti-
Sliding groove.
Preferably, the inner edge of the end of the nut body is circle, the outer rim of the end of the nut body
For waveform.
Preferably, the anti-skid bulge and antiskid groove is of same size.
Preferably, the screw thread is wedge thread, the screw thread includes pin thread and negative thread, the positive spiral shell
Line is parallel with the inner wall of the threaded hole, and the side flank angle of the negative thread is 30 degree, the negative thread it is another
The flank angle of side is 60 degree.
Preferably, being equipped with anti-skid washer in the bottom of the screw thread in the threaded hole.
Preferably, the outer rim of the anti-skid washer is flushed with the outer rim of the screw thread.
Preferably, the nut body uses integral molding techniques, the nut body uses alloy steel
It is made.
Beneficial effects of the present invention: nut body outer surface can be improved by anti-skid bulge and antiskid groove in the present invention
Non-skid property prevent from loosening by wedge thread and anti-skid washer, alloy steel is used by nut body, intensity is high,
Stable type is good.
Feature and advantage of the invention will be described in detail by embodiment combination attached drawing.

[specific embodiment]
In order to make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments, to this
Invention is further elaborated.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention,
The range being not intended to restrict the invention.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to keep away
Exempt from unnecessarily to obscure idea of the invention.
Refering to fig. 1 and Fig. 2, a kind of high strength anti-loose nut with antiskid effect of the present invention, including nut body 1, spiral shell
The diameter at the middle part of maternal body 1 is greater than the diameter of end, and the diameter of nut body 1 successively decreases from middle part to both ends, nut body 1
Middle part is run through up and down equipped with threaded hole 2, offers screw thread 3 on the inner wall of threaded hole 2, along height side on the outer wall of nut body 1
To several anti-skid bulges 4 are uniformly provided with, antiskid groove 5 is equipped between anti-skid bulge 4.
Wherein, the inner edge of the end of nut body 1 is circle, and the outer rim of the end of nut body 1 is waveform.
Wherein, anti-skid bulge 4 and antiskid groove 5 is of same size.
Wherein, screw thread 3 is wedge thread, and screw thread 3 includes pin thread 31 and negative thread 32, pin thread 31 and threaded hole 2
Inner wall is parallel, and the side flank angle of negative thread 32 is 30 degree, and the flank angle of the other side of negative thread 32 is 60 degree.
Wherein, anti-skid washer 6 is equipped in the bottom of screw thread 3 in threaded hole 2.
Wherein, the outer rim of anti-skid washer 6 is flushed with the outer rim of screw thread 3.
Wherein, nut body 1 uses integral molding techniques, and nut body 1 is made of alloy steel.
