Abstract
The utility model relates to a special nut which comprises a nut body. A threaded hole is formed in the nut body. The upper end face and the lower end face of the nut body are arch faces which are inwards concave. Anti-sliding nails are arranged on the arch faces. In the process of screwing the nut into a bolt or a screw rod, once the nut adheres to a connected part, the arch faces in contact with the surface of the connected part will deform and then generates elastic deforming force. The elastic deforming force can force the nut to be tightly pressed on the surface of the connected part. The friction between the nut and the connected part will be enlarged, thus, when the nut is subjected to strong vibration, the nut can still maintain the ideal anti-loosening performance. In addition, when the arch faces deform, the threads on the nut can cling to the threads of the bolt or the screw rod and meanwhile, the anti-sliding nails can better prevent the nut from loosening.
Description
Technical field
The utility model relates to a kind of fastener areas, relates in particular to a kind of profile nut.
Background technique
The working principle of nut is to adopt the frictional force between nuts and bolt to carry out self-locking.But the reliability of this self-locking will reduce in dynamic load.In some important occasions, we will take some locking measures, guarantee the reliability of nut check.Conventionally nut is all the part that machinery is closely coupled together, and by the screw thread of inner side, with equal-specification nuts and bolt, just can link together, for other component are fastenedly connected.Upper and lower two end faces of plain nut mostly are smooth plane, and this smooth plane and the frictional force being connected between component surface are generally all very little, and when meeting compared with strong vibration, nut will become flexible, and therefore, the anti-loosening property of nut needs to improve.
Model utility content
The purpose of this utility model is in order to overcome deficiency of the prior art, thereby a kind of profile nut is provided.
A profile nut, comprises nut body, and described nut body is provided with tapped hole, and upper and lower two end faces of described nut body are the arcuate surface concaving, and described arcuate surface is provided with non-skid nail.
Adopt the beneficial effect of technique scheme to be:
The utility model nut has the following advantages: upper with prior art nut, lower two end faces are smooth plane difference, on the nut body of the utility model nut, lower two end faces are the arcuate surface concaving, therefore, at the utility model nut, be screwed in the process of bolt or screw rod, after once it is fitted in and is connected on component, with be connected the arcuate surface that component surface contacts and will deform, and produce elastic deformation force thereupon, this elastic deformation force can force the utility model nut to be pressed in tightly on the surface that is connected component, therefore the utility model nut and the frictional force being connected between component can increase, like this, when the utility model nut is subject to compared with strong vibration, still can there is comparatively ideal anti-loosening property.In addition, when arcuate surface deforms, the screw thread on the utility model nut can be held tightly on bolt or screw flight, and set non-skid nail can better prevent nut loosening simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model profile nut structural representation.
In figure: 1-nut body, 2-tapped hole, 3-arcuate surface, 4-non-skid nail.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of profile nut, comprise nut body 1, described nut body 1 is provided with tapped hole 2, upper and lower two end faces of described nut body 1 are the arcuate surface 3 concaving, described arcuate surface 3 is provided with non-skid nail 4, and the screw thread on the utility model nut can be held tightly on bolt or screw flight, and set non-skid nail 4 can better prevent nut loosening simultaneously.
Described non-skid nail 4 is more than two.
Claims (2)
