The utility model has the advantages that: the utility model provides a pair of two-way locknut, the clearance between bolt and nut can be eliminated better in the nut middle part adoption of tapered structure when assembly and use, the locking ring is adopted at both ends from top to bottom simultaneously, the self-locking power that produces by two locking rings can firmly lock the upper and lower both ends of nut and die on the bolt, guarantee the stability of connection, the effectual nut that prevents is not hard up, reach whole fastening locking effect, the problem of the nut pine take off the inefficacy in assembly and use has been solved, high safety and reliability, therefore, the clothes hanger is strong in practicability.
Drawings
Fig. 1 is a schematic structural view of a preferred embodiment of the bidirectional locknut of the present invention;
FIG. 2 is an assembled cross-sectional view of FIG. 1;
the parts in the drawings are numbered as follows: 1. the nut comprises a nut body, 2, a locking boss, 3, an anti-loosening ring, 11, a threaded hole, 12, a conical counter bore, 21, a circular boss, 22, a conical table body, 23, a mounting hole, 24 and an annular groove.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1 to 2, an embodiment of the present invention includes:
a bidirectional locknut comprises a nut body 1, a lockboss 2 and a lockring 3.
The middle part in the nut body 1 is provided with screw hole 11, the upper and lower both ends of screw hole 11 symmetry respectively are provided with through connection's toper counter bore 12, locking boss 2 sets up the upper and lower both ends at nut body 1 through toper counter bore 12 cooperation respectively, anti-loosening ring 3 sets up on the inner wall of locking boss 2 upper end opening part.
As shown in fig. 2, the anti-loose boss 2 comprises a circular boss 21 and a conical boss 22 which are integrally formed, and the conical boss 22 is arranged at the bottom of the circular boss 21 and is provided with a mounting hole 23 which is coaxial with the threaded hole 11 in a penetrating manner. Wherein, the inner wall of the round boss 21 is provided with an annular groove 24 for installing the anti-loose ring 2.
The number of locking boss 2 is 2, is the symmetry respectively and sets up. The conical boss 22 in the anti-loosening boss 2 is matched with the conical counter bore 12. During installation, the anti-loosening boss 2 is fastened with the conical counter bore 12 through the matched conical boss 22 and is arranged at the upper end and the lower end of the nut body 1 respectively, the anti-loosening boss 2 is pressed in the nut body 1 through a press, the connection is firm, and the anti-loosening boss is not easy to break away.
The bottom of the conical counter bore 12 can force the bottom of the conical boss 22 to uniformly generate elastic deformation (contraction) along the radial direction, so that thread gaps are eliminated and the bolt is tightened.
