Authorization Notice No. is CN204646942U, and authorized announcement date is that the Chinese utility model patent of 2015.09.16 is open
A kind of anchor locking-nuts with twolug, its auto-lock function is by being machined with female thread on one end inwall of nut body and receiving
Mouth processing obtains self-locking section to realize, arranges closing-in structure on nut body, and processing of closing up is to be sent out by making female thread
The shape that changes realizing, when bolt is screwed into closing in position closing in spreading, make bolt and the spiral shell screwing using the elastic force closing up
Parent compresses, thus playing locking effect.
However, due to must arrange closing-in structure, the screwed hole of nut body end will deform, so in deformation process
It is easy for making to occur crackle in nut body, this will largely effect on the serviceability of self-locking nut.And due to by Product processing size
Error and closing in data floating, be easily caused the discordance of product locking property, even do not have locking effect not
Sharp phenomenon.In addition, this closing-in structure is when using, the locking torque when being screwed into first time for the bolt is maximum, Jing Guoji
Secondary be screwed into after, locking torque will diminish even zero, the serviceability of impact self-locking nut.
Utility model content

Specific embodiment
The enforcement of latch assembly is for example shown in Fig. 1 ~ Fig. 4, the supporting plate self-lock nut be connected including bolt 4 and with bolt 4, should
Supporting plate self-lock nut is a kind of monaural supporting plate self-lock nut, and monaural supporting plate self-lock nut is included supporting plate 1 and is integrally formed with supporting plate 1
The nut body 2 of setting, nut body 2 is provided with female thread, the tooth form side of thread the same side of described female thread is by positioned at tooth
The tooth bottom side 5 at bottom and the crest side surfaces 6 being located between crest and tooth bottom side 5 form, the axle of tooth bottom side 5 and nut body 2
The angle of line is less than the angle of crest side surfaces 6 and the axis of nut body 2, in this embodiment, tooth bottom side 5 and nut body 2
The angle of axis is 30 degree, and crest side surfaces 6 are 60 degree with the angle of the axis of nut body 2.
Supporting plate 1 includes the otic placode positioned at nut body 2 periphery side, supporting plate 1 is provided with for accordingly part phase to be connected
Attachment structure even, in this embodiment, described attachment structure is two riveted holes 3 being arranged on otic placode.In other enforcements
In example, as shown in Fig. 5 ~ Fig. 6, supporting plate self-lock nut can also be a kind of anchor locking-nuts with twolug, anchor locking-nuts with twolug
The nut body 2 equally also including supporting plate 1 and being integrally formed setting with supporting plate 1, nut body 2 is provided with female thread, female thread
Structure is identical with monaural supporting plate self-lock nut.Difference is：The supporting plate 1 of anchor locking-nuts with twolug includes being symmetrically arranged in
Two otic placodes of nut body 2 periphery both sides, supporting plate 1 is provided with for the attachment structure that accordingly part to be connected is connected, described
Attachment structure is specially separately positioned on the riveted holes 3 on two otic placodes.
During use, first pass through riveted holes 3 and monaural supporting plate self-lock nut or anchor locking-nuts with twolug are fixed on the company for the treatment of
On fitting, anchor locking-nuts with twolug due to having symmetrical otic placode, its stress balance, be suitable for being completely embedded property require higher
Occasion, when limited by installing space cannot using anchor locking-nuts with twolug when, can select using monaural supporting plate self-lock nut.
After supporting plate self-lock nut is fixed on part to be connected, joined with supporting plate self-lock nut with through connector using common bolt 4
Close the connection that can achieve mechanism.
When bolt 4 and supporting plate self-lock nut are tightened, the externally threaded crest of bolt 4 tightly withstands on tooth bottom side 5,
The angle of the normal force so producing in the externally threaded crest touching position of tooth bottom side 5 and bolt 4 and the axis of nut body 2
Be exactly 60 degree, compare there is no a tooth bottom side 5 and only crest side surfaces 6 when, this angle is only 30 degree, therefore nut body 2 and bolt 4
The locking frictional force producing when matching is bigger, and this makes to coordinate between nut body 2 and bolt 4 and is closely not easy to occur getting loose.
That is, nut body 2 achieves that self-locking when matching with bolt 4 it is not necessary to extra locking measures, receipts need not be set
Mouth structure, thoroughly solves in prior art and needs setting closing-in structure to lead to supporting plate self-lock nut easily to occur to realize self-locking
The problem of crackle, and then also just solve the error being easily subject to Product processing size during setting closing-in structure and closing in data
Float and affect and the discordance of product locking property leading to, the problem even not having locking effect.
Meanwhile, the auto-lock function of supporting plate self-lock nut is that the tooth bottom side being 30 degree by the angle with the axis of nut body comes
Realize, compared with the closing-in structure relying on elastic deformation in prior art, the tooth bottom side face stability directly processing is more
Height, is not susceptible to deformation failure, therefore, it is possible to the stable holding locking torque when being screwed into for the bolt, extends supporting plate self-lock nut
Service life.
In the other embodiment of latch assembly：Supporting plate and nut body can not be and be integrally formed it is also possible to be fabricated separately
After weld together；Two otic placodes of anchor locking-nuts with twolug may not be and are symmetricly set on nut body periphery；Connect knot
Structure can not be riveted holes or screwed hole, by bolt, supporting plate self-lock nut is fixed on part to be connected during use；
Tooth bottom side can not be 30 degree with the angle of the axis of nut body, and the angle of the axis of crest side surfaces and nut body can not also
It it is 60 degree, as long as the angle of the axis of tooth bottom side and nut body is less than the angle of crest side surfaces and the axis of nut body.
The enforcement of supporting plate self-lock nut is for example shown in Fig. 1 ~ Fig. 6, the concrete structure of supporting plate self-lock nut and above-mentioned locking group
Supporting plate self-lock nut described in part embodiment is identical, will not be described in detail herein.
