Description
Technical Field
The utility model relates to a fastener field especially relates to a high strength locknut fastener.
Background
A nut is a fastener that is internally threaded and cooperates with a bolt, and a mechanical part that is internally threaded and cooperates with a threaded rod for transmitting motion or power. When in use, the nut is screwed together with the bolt or the screw rod to fasten the machine, and is an element which is necessary for all production and manufacturing machines.
The nut and the bolt transmit tightening force through the thread teeth to realize workpiece compression, but in actual use, the thread teeth can generate elastic deformation due to stress, so that the thread pitch is changed, and only part of the thread teeth can actually bear load.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide a simple structure, antivibration locking and safe and reliable's high strength locknut fastener.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:
a high-strength locknut fastener comprises a main nut and an auxiliary nut which are connected with a bolt or a stud in a pre-tightening way, and is characterized in that a circle of annular groove is formed in the end face of the main nut, a circle of annular body matched with the annular groove is formed in the end face of the auxiliary nut, and the annular body and the annular groove are in interference fit to realize the fastening connection of the main nut and the auxiliary nut; the main nut between the annular groove and the inner side of the main nut is provided with a plurality of breaking lines along the axis direction, and the breaking lines are arranged along the inner side of the main nut at intervals in the circumferential direction.
The utility model discloses a further improvement lies in, is connected with vice nut the terminal surface outer fringe of main nut is formed with the round recess, is connected with main nut be formed with the round on vice nut's the terminal surface with the recess cladding with the boss of recess adaptation block, can make main, vice nut connect inseparabler, and the aesthetic property is better.
The utility model discloses a further improvement lies in, main nut and vice nut are hexagon nut.
The utility model discloses a further improvement lies in, the outer wall of main nut and vice nut all is equipped with anti-skidding stripe, plays anti-skidding effect, is convenient for connect soon.
The utility model discloses a further improvement lies in, vice nut, ring body and boss structure as an organic whole.
The utility model has the advantages that: the utility model discloses a main, vice nut cooperation has increased the number of teeth of the hookup screw thread that participates in and bear, improves the intensity of hookup, can realize fastening with bolt or double-screw bolt hookup, prevents not hard up safe and reliable.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1-4, a high-strength locknut fastener comprises a main nut 1 and an auxiliary nut 2 which are connected with a bolt or a stud in a pre-tightening manner, wherein a circle of annular groove 3 is formed in the end surface of the main nut 1, a circle of annular body 4 matched with the annular groove 3 is formed in the end surface of the auxiliary nut 2, and the annular body 4 and the annular groove 3 are in interference fit to realize the fastening connection of the main nut 1 and the auxiliary nut 2; the main nut 1 between the annular groove 3 and the inner side of the main nut 1 is provided with a breaking line 5 along the axis direction, and the breaking lines 5 are provided with a plurality of lines and are arranged at intervals along the circumferential direction of the inner side of the main nut 1.
Specifically, the outer edge of the end face of the main nut 1 connected with the auxiliary nut 2 is provided with a circle of grooves 6, the end face of the auxiliary nut 2 connected with the main nut 1 is provided with a circle of bosses 7 which are used for covering the grooves 6 and are clamped with the grooves 6 in a matching mode, so that the main nut 1 and the auxiliary nut 2 can be connected more tightly, and the appearance is better.
Specifically, the main nut 1 and the sub nut 2 are both hexagonal nuts.
Specifically, the outer walls of the main nut 1 and the auxiliary nut 2 are provided with anti-slip stripes 8, so that an anti-slip effect is achieved, and the screwing is facilitated.
The working principle is as follows: firstly, screwing the main nut 1 on the bolt or the stud, then screwing the auxiliary nut 2, gradually inserting the annular body 4 into the annular groove 3 along with the gradual approach of the main nut 1 and the auxiliary nut 2 in the screwing process of the auxiliary nut 2, and tightly pressing the wall of the main nut 1 between the annular groove 3 and the inner side of the main nut 1 on the surface of the bolt or the stud under the action of interference fit and the fracture line 5 to realize fastening.
The described embodiments are only some, but not all embodiments of the invention. 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.
