Abstract
The utility model discloses a locknut which comprises a locknut body provided with a main threaded hole. The locknut body is provided with a positioning threaded hole vertical to the main threaded hole and penetrating to the inner side of the main threaded hole. The positioning threaded hole is provided with a positioning bolt matched with the positioning threaded hole. The bottom of the positioning bolt is provided with a sharp end which is in an inverted-cone shape. The locknut solves the problem that an existing nut is prone to loosening under a vibration environment, and is not prone to loosening.
Description
Technical field
The utility model relates to a kind of threaded fastener, relates in particular to a kind of lock nut.
Background technique
At present, the nut on the market does not have anti-loose structure substantially, when being fixed with bolt, if long-term work under vibration environment, causes getting loose of nut easily, affects the normal operation of equipment, can bring certain potential safety hazard to the staff yet.
Summary of the invention
The problem that the utility model gets loose under vibration environment easily in order to solve present nut proposes a kind of lock nut that is difficult for getting loose.
To achieve these goals, the utility model is by the following technical solutions: a kind of lock nut, comprise the nut main body that is provided with the main thread hole, described nut main body is provided with vertical with the main thread hole and is through to positioning spiro pit in the main thread hole, and described positioning spiro pit is provided with the holding down bolt with the positioning spiro pit coupling.
As preferably, described holding down bolt bottom is provided with the tip.
As preferably, described tip is inverted conical.
Therefore, the utlity model has following beneficial effect: (1) is provided with holding down bolt, prevents that nut from getting loose; (2) technique is simple, and is easy to process; (3) simple in structure, cost is low.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Fig. 3 is a kind of structural representation of the utility model nut main body.
1: nut main body; 2: holding down bolt; 3: the tip; 4: the main thread hole; 5: positioning spiro pit.
Embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
A kind of lock nut, referring to Fig. 1--3, comprise the nut main body 1 that is provided with main thread hole 4, described nut main body 1 be provided with one vertical with main thread hole 4 and be through to positioning spiro pit 5 in the main thread hole 4, described positioning spiro pit 5 is provided with the holding down bolt 2 with positioning spiro pit 5 couplings, and described holding down bolt 2 bottoms are provided with the tip 3 of inverted conical.
During use, nut main body 1 is installed to the required part that is tightened on the supporting bolt, the holding down bolt 2 on the fastening nut main body 1 again, so that on the bolt of tip 3 diebacks in main thread hole 4 of holding down bolt 2, stop nut main body 1 and main thread hole 4 inner bolts to relatively rotate, prevent that nut main body 1 from getting loose.
