Abstract
The invention relates to a nut locking device. The nut locking device consists of a locking nut and a self-locking nut, wherein the locking nut consists of a first internal thread, a conical elastic sheet locking part, an external thread part and a first pulling and twisting part; and the self-locking nut consists of a second pulling and twisting part, a closing part, a pressing part and a second internal thread. When the nut locking device is connected with a connecting piece, the first internal thread of the locking nut is in threaded connection with the connecting piece, and the locking nut is twisted in place through the first pulling and twisting part; the second internal thread of the self-locking nut is matched with the external thread part of the locking nut, the conical elastic sheet locking part of the locking nut is matched with the closing part of the self-locking nut, and the locking nut and the self-locking nut are twisted in place through the second pulling and twisting part; and the pressing part is pressed by a pressing hoop. The nut locking device consists of the locking nut and the self-locking nut, so that installation reliability is ensured, and installation efficiency is improved.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of nut lock.
Background technique
In industries such as Aeronautics and Astronautics, boats and ships, automobile, railways; The component that the environment that some vibratilities are strong is worked down; In installation process, need a kind ofly to have locking and be connected with the fastening piece of auto-lock function, have good freedom from vibration, locking, be convenient to quick mounting, dismounting.
Summary of the invention
The technical problem that the present invention will solve provides the nut lock that has locking mechanism that a kind of torque-controllable is installed.
A kind of nut lock partly is made up of locking nut and self-locking nut two; Locking nut is pulled to twist partly and is formed by first internal thread, taper shell fragment locking part, outside thread part, first; Self-locking nut is pulled by second and is twisted partly, closes up partly, compresses partly and form with second internal thread.
When nut locking device was connected with connector, first internal thread with locking nut was threaded with connector earlier, partly locking nut was screwed to the position by first twisting; Second internal thread with said self-locking nut partly matches with the external screw thread of locking nut then, and the taper shell fragment locking of locking nut partly partly matches with the closing in of self-locking nut, partly locking nut and self-locking nut is screwed to the position by second twisting; Compress with pressing hoop will compress partly at last.
The present invention is made up of locking nut and self-locking nut, has both guaranteed the reliability of installing, and has improved installation efficiency simultaneously again.
Description of drawings
Fig. 1 is the structural representation of locking nut in the locking device of the present invention;
Fig. 2 is the structural representation of self-locking nut in the locking device of the present invention;
Fig. 3 is the scheme of installation of locking device of the present invention and link.
Embodiment
In order to deepen to understanding of the present invention; Below in conjunction with embodiment the present invention is described in further detail; This embodiment only is used to explain the present invention; Do not constitute qualification, all any modifications of within spirit of the present invention and principle, being done, be equal to replacement and improvement etc., all should be included within protection scope of the present invention protection domain of the present invention.
Nut lock of the present invention partly is made up of locking nut and self-locking nut two.
As shown in Figure 1, locking nut by first internal thread 1, the locking of taper shell fragment partly 2, outside thread partly 3, first pulls and twists partly 4 and form; As shown in Figure 2, self-locking nut is pulled by second and is twisted partly 5, closes up partly 6, compresses partly 7 and second internal thread 8 and form.
As shown in Figure 3, assembly a kind of nut lock through locking nut and self-locking nut with locking and self-locking structure.When locking device of the present invention was connected with link, earlier first internal thread 1 with locking nut was threaded with link, pulled through first and twisted part 4 locking nut is screwed to the position; Then second internal thread 8 of self-locking nut partly 3 is matched with the outside thread of locking nut, the taper shell fragment locking of locking nut partly 2 partly 6 matches with the closing in of self-locking nut, pulls through second and twists part 5 locking nut and self-locking nut are screwed to the position.7 compress with pressing hoop will compress partly at last.
Compared with prior art, the technique effect that the present invention reaches forms self-locking for the present invention produces distortion when mounted under responsive to axial force; The instead spring washer is locking; Alleviate product weight, improved efficiency of assembling greatly, be prone to realize self-assembly; Simple and reliable for structure, can be widely used in mechano-electronic industry non-bearing position.
