the utility model provides a locking hexagonal round nut, includes first nut and second nut, sets up the screw hole of the same thread size on two nuts, and the screw hole upper end of first nut is provided with columniform bulge, and bulge and screw hole eccentric settings set up, set up the fixed orifices that is linked together with the screw hole on the bulge, set up the screw thread the same with screw hole thread size on the fixed orifices, a side of second nut is provided with the depressed part towards another side, the bulge insert in the depressed part just laminates mutually, bulge periphery side still is provided with the second bulge on the first nut, has the interval between second bulge and the bulge, still be provided with on the second nut and be annular second depressed part, the second bulge laminating inserts the second depressed part, be provided with the through-hole on the bulge, clearance and fixed orifices between two bulges of through-hole intercommunication, the second through-hole has been seted up on the depressed part, two through-hole intercommunication two depressed parts of second through-hole, the through-hole communicates with the second through-hole, is provided with the connecting rod in two through-holes, and connecting rod one end is provided with the elastic cushion, and the other end supports second bulge inside wall.
The utility model relates to a locking hexagonal round nut's further improvement part lies in, and first bulge top is provided with the elastic ring pad, and the elastic ring pad supports first depressed part, and the bolt of screw hole spiro union passes the elastic ring pad.
The utility model relates to a locking hexagonal round nut's further improvement part lies in, bulge and first nut integrated into one piece.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses set up two nuts, and two nuts pass through bulge, sunken part and partly form a whole, increased the stability of connection, simultaneously, add the connecting rod and further support tightly to the bolt of spiro union, locking effect when having increased nut connecting bolt.
Drawings
FIG. 1 is a schematic view of the present invention;
in the figure: 1 first nut, 2 second nut, 3 protrusions, 4 recesses, 5 second protrusions, 6 second recesses, 7 through holes, 8 second through holes.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a locking hexagonal round nut comprises a first nut 1 and a second nut 2, threaded holes with the same thread size are formed in the two nuts, a cylindrical protruding portion 3 is arranged at the upper end of the threaded hole of the first nut, the protruding portion and the threaded hole are eccentrically arranged, a fixing hole communicated with the threaded hole is formed in the protruding portion, threads with the same thread size as the threaded hole are formed in the fixing hole, the protruding portion and the first nut are integrally formed, and threads on the protruding portion fixing hole and threads of the threaded hole are integrally formed. One side surface of the second nut is provided with a concave part 4 towards the other side surface, and the convex part of the first nut is inserted into the concave part and is attached to the concave part. Because bulge and depressed part are eccentric for the screw hole, and then solitary nut can not break away from another nut and appear becoming flexible, and two nuts regard as a whole for the bolt promptly, and the solitary nut can not appear becoming flexible, and then connects in the bolt by two nuts, has increased the stability of connecting. Further, bulge periphery side still is provided with second bulge 5 on the first nut, there is the interval between second bulge and the bulge, still be provided with on the second nut and be annular second depressed part 6, the second depressed part is inserted in the laminating of second bulge, be provided with through-hole 7 on the bulge, clearance and fixed orifices between two bulges of through-hole intercommunication, second through-hole 8 has been seted up on the depressed part, two depressed parts of second through-hole intercommunication, the through-hole communicates with the second through-hole, be provided with the connecting rod in two through-holes, connecting rod one end is provided with the cushion, the other end supports second bulge inside wall. The connecting rod is additionally arranged, on one hand, the limit between the two nuts is enhanced, on the other hand, the transverse fastening force of the bolt is increased, and the anti-loosening effect is enhanced. Furthermore, the top end of the first protruding part is provided with an elastic ring pad, the elastic ring pad abuts against the first recessed part, and a bolt in threaded hole screwing penetrates through the elastic ring pad.
The utility model discloses a theory of operation does: the two nuts are overlapped, the connecting rod is inserted into the through hole and the second through hole from the threaded hole, then the bolt is screwed, the bolt penetrates through the elastic ring pad, meanwhile, the bolt is extruded by the elastic pad on the connecting rod, the two nuts, the elastic ring pad and the elastic pad are integrally used for fastening the bolt, and the nut is guaranteed to have a strong anti-loosening effect.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
