The disk also has axial spacing apart from Nut pole front end face.
Nut pole outer diameter after the disk is less than the outer diameter of the Nut pole before disk.
A kind of fastener including screw rod, further includes above-mentioned stop nut, the internal thread of the Nut pole of the stop nut
For coordinating with the external screw thread of screw rod.
By using above-mentioned technical proposal, the utility model at least has the advantages that：
1st, the utility model is interacted using Nut pole and nut set, because the back end outer surface of Nut pole is equipped with taper,
And osculum is provided on Nut pole, nut set rear inside is equipped with tapered hole, will be by spiral shell when nut set is screwed on Nut pole
Female bar is shunk toward tight, and nut set is twisted tighter, and screw rod is embraced tighter by Nut pole, and anti-loosing effect is better.
2nd, by setting aperture and the upper elastic support cooperation of nut set on disk, when nut cover screwing, nut set
On elastic support can be automatically inserted into the aperture on Nut pole disk Nei formation self-locking, play further anti-loosing effect,
During decomposition, it is not required that carry out any processing to elastic support, it is possible to directly be unclamped with spanner.
3rd, the resistance when stop nut anti-loosing effect of the utility model can keep initial for a long time is constant, will not because vibrations,
Time, the influence of environment, and reduce anti-loosing effect.
4th, the resistance of the stop nut anti-loosing effect of the utility model only threaded last several circles is larger, remaining screw thread
Loosening, tighten does not influence its fast tight, quick-release effect.
Description of the drawings
Above-mentioned is only the general introduction of technical solutions of the utility model, in order to better understand the technology hand of the utility model
Section, below in conjunction with attached drawing, the utility model is described in further detail with specific embodiment.
Fig. 1 is the assembling structure schematic diagram of the utility model fastener (containing screw rod, Nut pole and nut set)；
Fig. 2 is the overall structure diagram of Nut pole；
Fig. 3 is the schematic cross-sectional view of Nut pole；
Fig. 4 is the schematic cross-sectional view of nut set；
Fig. 5 is the side structure schematic view of nut set.
Specific embodiment
It should be noted that for ease of description, front and back position is defined in the utility model, arrow shown in Fig. 1
Direction is from back to front, is not used in restriction the scope of protection of the utility model.
As shown in Figs. 1-5, the utility model provides a kind of stop nut, including Nut pole 1 and nut set 2；Nut pole 1
It is equipped with internal thread and external screw thread；Taper is equipped at 1 back end outer surface 11 of Nut pole, and is opened forward from rear end on Nut pole 1
Equipped with a plurality of opening 12；Nut set 2 is equipped with internal thread (screw pitch of the two screw thread, the diameter one coordinated with 1 external screw thread of Nut pole
Cause), nut covers 2 rear insides and is equipped with interior big outer small tapered hole 21, tapered hole 21 and the cone at Nut pole back end outer surface 11
Degree cooperation.
In use, above-mentioned stop nut is used with screw rod 3 as a set of appended claims, specifically, first Nut pole 1 is twisted
The position needed on screw rod 3, the two are coordinated by internal and external threads, then nut set 2 is screwed on Nut pole 1, are gradually screwed to
Maximum position, because the back end outer surface of Nut pole 1 is equipped with taper, and opening 12 is provided on Nut pole 1, nut is covered in 2 rear ends
Side is equipped with tapered hole 21, when nut set 2 is screwed on Nut pole 1, will shrink Nut pole 1 toward tight, nut set 2 is twisted more
Tightly, screw rod 3 is embraced tighter by Nut pole 1, and anti-loosing effect is better.
Preferably, above-mentioned tapered hole 21 is consistent with the taper of Nut pole back end outer surface 11, Nut pole back end outer surface 11
Taper at outer diameter be more than nut set in tapered hole 21 aperture.
The disk 13 bigger than Nut pole outer diameter is additionally provided in 1 front end of Nut pole, disk 13 is equipped with one or more small
Hole 14, aperture 14 can be perforation or non-through shrinkage pool, and a plurality of opening 12 extends to the root of disk 13 from the rear end of Nut pole；
Nut covers 2 front end faces and is equipped with one or more elastic supports 25 coordinated with aperture 14.By setting the aperture on disk 13
14 coordinate with the elastic support 25 on nut set 2, and when nut set 2 is tightened, the elastic support 25 on nut set 2 rises and can insert automatically
Enter and self-locking is formed into the aperture 14 on the disk 13 of Nut pole 1, play further anti-loosing effect, when decomposing, be also not required to
Any processing is carried out to elastic support 25, it is possible to directly be unclamped with spanner.
Preferably, it can be covered in nut and be equipped with cavity 22 in 2 in an axial direction, fixed pivot is equipped with successively by rear to preceding in cavity 22
23rd, spring 24 and the elastic support 25, the front end face of one end stretching nut set 2 of elastic support 25 coordinate with aperture 14.
Those skilled in the art will envision that by the location swap of elastic support 25 and aperture 14 can also realize nut set with
The interlocking purpose of Nut pole.
Preferably, disk 13 also has axial spacing apart from 1 front end face of Nut pole, retains the axial direction spacing, can conveniently pull
Hand is fixedly clamped.
Preferably, the Nut pole outer diameter after disk 13 is less than the outer diameter of the Nut pole before disk 13, thin after thick before such
Setting can ensure the structural strength of Nut pole and be conducive to the contraction holding at rear portion.
In conclusion the stop nut of the utility model, by the interaction after Nut pole and nut cover screwing, by spiral shell
Female bar is tightly embraced together with screw rod, and structure biggest advantage is that resistance when anti-loosing effect can keep initial for a long time is not
Become, will not be because of vibrations, the influence of time, environment, and reduce anti-loosing effect, and the resistance of anti-loosing effect only threaded finally several circles
Power is larger, remaining screw thread, which loosens, tighten, does not influence its fast tight, quick-release effect.
The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form
Limitation, those skilled in the art make a little simple modification, equivalent variations or modification using the technology contents of the disclosure above,
It falls within the protection scope of the present utility model.
