Abstract
A nut belongs to a fastener, is frequently matched with a bolt or a screw, and includes a nut body, wherein a screw hole is arranged on the nut body; and upper and lower end surfaces of the nut body are internally-sunken arched surfaces. The nut still has satisfactory locking property under rather strong vibration.
Description
Technical field:
The utility model relates to a kind of fastening piece, specifically is a kind of nut.
Background technique:
We know, nut usually and bolt or screw rod be used, be used for other component are fastenedly connected.Mostly upper and lower two end faces of plain nut are smooth plane, and this smooth plane is generally all very little with the frictional force that is connected between component surface, and when meeting than strong vibration, nut will become flexible, and therefore, the anti-loosening property of nut needs to improve.
The model utility content:
The technical problem that the utility model will solve is, provides a kind of when receiving than strong vibration, still has the nut of desirable anti-loosening property.
The technical solution of the utility model is, a kind of nut with following structure is provided: comprise nut body, nut body is provided with tapped hole, and wherein, upper and lower two end faces of nut body are the arcuate surface that concaves.
After adopting above structure, compared with prior art, the utility model nut has the following advantages: with upper and lower two end faces of existing technology nut is that smooth plane is different; Upper and lower two end faces of the nut body of the utility model nut are the arcuate surface that concaves, and therefore, are screwed in the process of bolt or screw rod at the utility model nut; After in case it is fitted in and is connected on the component; Being connected the contacted arcuate surface of component surface with quilt will deform, and produces the elastic deformation force thereupon, and this elastic deformation force can force the utility model nut to be pressed in tightly by on the surface of connection component; Therefore the utility model nut can increase with the frictional force that is connected between the component; Like this, when the utility model nut receives than strong vibration, still can have comparatively ideal anti-loosening property.In addition, when arcuate surface deformed, the screw thread on the utility model nut can be held tightly on bolt or screw flight, and this also can strengthen the anti-loosening property of the utility model nut.
Description of drawings:
Fig. 1 is the stereochemical structure profile schematic representation of the utility model nut.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model nut is done further explain:
As shown in Figure 1, in this embodiment, the utility model nut comprises nut body 1, and nut body 1 is provided with tapped hole 2, and the upper-end surface of nut body 1 and lower end surface are the arcuate surface 3 that concaves.
The method for using of the utility model nut is: as shown in Figure 1, the utility model nut usually is used with bolt or screw rod (not shown), when fastening during by connection component (not shown); Can the utility model nut be screwed on bolt or the screw flight; In the time of on the utility model nut is fitted in by the connection component, continue rotation the utility model nut, being connected the contacted arcuate surface 3 of component surface with quilt will deform; And produce the elastic deformation force thereupon; This elastic deformation force then can force the utility model nut to be pressed in tightly by on the surface of connection component, and therefore the utility model nut can increase with the frictional force that is connected between the component, like this; When the utility model nut receives than strong vibration, still can have comparatively ideal anti-loosening property.In addition, when arcuate surface 3 deformed, the screw thread in the utility model nut upper screwed hole 2 can be held tightly on bolt or screw flight, and this also can strengthen the anti-loosening property of the utility model nut.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
Claims (1)
1. a nut comprises nut body (1), and said nut body (1) is provided with tapped hole (2), it is characterized in that: upper and lower two end faces of said nut body (1) are the arcuate surface (3) that concaves.
