Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a locking nut with a spring washer. Background Art

[0002] In the field of mechanical fasteners, in order to prevent nuts from loosening, spring washers and flat washers are usually stacked on the fastening surface of the nut, and then the nut is tightened on the bolt. The elastic force of the spring washer is used to increase the friction between the matching threads of the nut and the bolt, thereby preventing the nut from loosening. However, when tightening multiple nuts, they need to be taken out multiple times, and too many parts are inconvenient to carry and easy to lose; the subsequent disassembly and assembly of the nuts also need to be stored separately to ensure that the gaskets are not lost, which makes the operation more troublesome during the disassembly and assembly of the bolts, causing inconvenience to the staff. Therefore, in order to solve the above problems, a locking nut with a spring washer is designed. Utility Model Content

[0003] In view of the shortcomings of existing fasteners, the purpose of the utility model is to provide a locking nut with a spring washer, which has the advantages of facilitating fastening operations and accelerating fastening efficiency.

[0004] To achieve the above-mentioned purpose, a technical solution adopted by the utility model is: a locking nut with a spring washer, comprising a nut body, a spring washer and a buckle washer, the bottom of the nut body is detachably provided with a buckle washer, a spring washer is provided between the buckle washer and the nut body, the bottom of the nut body is also provided with an annular groove for fixing the buckle washer, one end face of the buckle washer is provided with a plurality of buckles arranged at equal angles, the buckles are used to buckle into the annular groove at the bottom of the nut body, one side of the fastening surface of the buckle washer is also provided with a serrated groove, the serrated groove is used to provide friction resistance to prevent the nut from loosening;

[0005] Preferably, the axial width of the annular groove is greater than the axial movement distance of the buckle washer;

[0006] Preferably, the number of buckles on one side of the buckle washer is n, where n≥2;

[0007] Preferably, the spring washer can be directly welded and fixed to the nut body;

[0008] Preferably, the spring washer can be directly welded and fixed to the snap washer;

[0009] Preferably, the spring washer can be stacked directly between the snap washer and the nut body;

[0010] The beneficial effect of the utility model is that a detachable snap-in washer is arranged at the bottom of the nut body, and a spring washer is arranged between the snap-in washer and the nut body, so that only a single nut needs to be taken out during the nut tightening process, and there is no need to take different washers multiple times, thereby saving the preparation time for the tightening process and improving the overall tightening efficiency.
