Embodiment 1

[0020] This embodiment discloses a nut screw washer combination, including a screw 1 , a nut 2 and a washer 3 . The screw 1 is provided with a first groove 11 crossing the threads, and the nut 2 is provided with a second groove 21 crossing the threads.

[0021] The gasket 3 includes a ring body 31 and a protruding portion 32, and the ring body 31 is in the shape of an unclosed three-dimensional helix. The protruding portion 32 is fixedly connected to both ends of the ring body 31 . The protruding portion 32 protrudes toward the inner ring of the ring body 31 and both sides in the axial direction of the ring body 31 . like image 3 As shown, the bottom of the protruding portion 32 is a larger end 321, and the top is a smaller end 322. The larger end 321 of the protruding portion is located at half of the ring body, and the smaller end 322 is located at a position away from the ring body 31. There is an inclined part 323 between the larger end 321 and the smaller end 322 near...

Abstract

The invention discloses a screw, nut and gasket combination, a screw and a nut are respectively provided with a first groove and a second groove which transversely penetrate through threads, and the two ends of a gasket are provided with protruding parts. After the screw rod, the nut and the gasket are tightly connected, the protruding parts are clamped in the first groove and the second groove. According to the combination, a fastened nut can be effectively prevented from loosening under the vibration condition, the fastening effect of the nut is improved, and the good market value is achieved.

Description

technical field [0001] The invention relates to the field of fasteners, in particular to a screw nut washer combination. Background technique [0002] In many application scenarios, it is desirable to fasten the nut to the bolt in a permanently fastened manner, so that the nut will not loosen when exposed to a strong vibration environment. Typically, one prevents loosening by tightening one or more locknuts on the bolts behind the curtain to exert a locking force on the nuts. However, such a locknut requires additional parts, takes up more installation space, more installation materials and longer installation time. And this kind of locknut will still continue to loosen with the long vibration time in a strong vibration environment. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems and provide a screw nut washer combination. To achieve the above object, the present invention adopts the following technical ...
