Abstract
The utility model provides a self-locking nut, which comprises a nut, a first threaded sleeve, an anti-loosening ring and a second threaded sleeve, wherein the first threaded sleeve, the anti-loosening ring and the second threaded sleeve are sequentially screwed in the nut from one end to the other end; the anti-loosening ring is at least two and more than half rings and is a regular polygon. The utility model provides a from lock nut, with first swivel nut, prevent loose circle, second swivel nut by one end to the other end spiro union in proper order in the nut, the installation is nimble, convenient, but first swivel nut and second swivel nut length nimble selection to adjustable prevent that the loose circle is located the position of nut, the locking circle in the connecting piece of being convenient for and the nut is connected, reaches the auto-lock effect, and firm in connection is strong, is difficult for droing.
Description
Technical Field
The utility model relates to a fastener technical field especially relates to a self-locking nut.
Background
The self-locking nut is a nut capable of self-locking by friction force. The general nut can be loosened by itself due to vibration and other reasons in the using process, and in order to prevent the phenomenon, the self-locking nut is invented. The self-locking nut has the functions of anti-loosening and anti-vibration, and the working principle of the self-locking nut is generally self-locking by friction force. The self-locking nut is generally screwed into the self-locking threaded sleeve in the nut, the self-locking threaded sleeve is generally of an integrated structure, the installation is inconvenient, the position of an anti-loosening ring in the self-locking threaded sleeve in the nut is fixed and cannot be flexibly adjusted, the self-locking nut is screwed when the end of a connecting piece is connected, sometimes, the end of the connecting piece cannot extend to be connected with the anti-loosening ring, the self-locking effect cannot be achieved, and the connection is not firm.
In view of the above, there is a need for an improved self-locking nut in the prior art to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to disclose a from lock nut, with first swivel nut, prevent loose circle, second swivel nut by one end to the other end spiro union in proper order in the nut, the installation is nimble, convenient, but first swivel nut and second swivel nut length nimble selection to adjustable prevent the position that the loose circle is located the nut, the locking circle in the connecting piece of being convenient for and the nut is connected, reaches the auto-lock effect, firm in connection is strong, is difficult for droing.
In order to achieve the purpose, the utility model provides a self-locking nut, which comprises a nut, a first thread sleeve, an anti-loosening ring and a second thread sleeve, wherein the first thread sleeve, the anti-loosening ring and the second thread sleeve are sequentially screwed in the nut from one end to the other end; the anti-loosening ring is at least two and more than half rings and is a regular polygon.
In some embodiments, the first thread insert, the anti-loosening ring and the second thread insert abut end to end.
In some embodiments, the first and second inserts are the same length.
In some embodiments, the first and second inserts are not the same length.
In some embodiments, the anti-loosening ring is three rings.
In some embodiments, the anti-loosening ring is hexagonal.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a from lock nut, with first swivel nut, prevent loose circle, second swivel nut by one end to the other end spiro union in proper order in the nut, the installation is nimble, convenient, but first swivel nut and second swivel nut length nimble selection to adjustable prevent that the loose circle is located the position of nut, the locking circle in the connecting piece of being convenient for and the nut is connected, reaches the auto-lock effect, and firm in connection is strong, is difficult for droing.
Drawings
Fig. 1 is a schematic structural view of a self-locking nut of the present invention;
FIG. 2 is an exploded view of FIG. 1;
fig. 3 is a schematic view of the structure of the anti-loose ring shown in fig. 2.
Detailed Description
The present invention is described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and those skilled in the art should understand that the functions, methods, or structural equivalents or substitutions made by these embodiments are within the scope of the present invention.
A self-locking nut as shown in fig. 1-3, comprising a nut 1, a first thread insert 2, a locking ring 3, and a second thread insert 4, which are screwed in the nut 1 from one end to the other end in sequence. The first thread insert 2, the anti-loosening ring 3 and the second thread insert 4 are all made of stainless steel.
Under natural conditions, the outer diameters of the first thread insert 2, the anti-loose ring 3 and the second thread insert 4 are all larger than the inner diameter of the nut 1, so that the first thread insert 2, the anti-loose ring 3 and the second thread insert 4 can be tightly connected in the nut 1.
The anti-loosening ring 3 is at least two and more than half rings, and in the embodiment, the anti-loosening ring 3 is three rings. The anti-loose ring 3 is a regular polygon, and in this embodiment, the anti-loose ring 3 is a hexagon.
The first thread insert 2, the anti-loosening ring 3 and the second thread insert 4 are abutted end to ensure the connection continuity of the first thread insert 2, the anti-loosening ring 3 and the second thread insert 4. First swivel nut 2 is the same with 4 length of second swivel nuts, also can not be the same, but first swivel nut 2 and 4 length of second swivel nuts are nimble to be selected to adjustable anti-loosening ring 3 is located the position in nut 1, and the locking ring 3 that is convenient for connecting piece (not shown) and nut 1 is connected, reaches the auto-lock effect, and firm in connection is strong, is difficult for droing.
The above list of details is only for the practical implementation of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention should be included in the scope of the present invention.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
