Abstract

The utility model discloses a kind of anti-skidding flange nuts, there is the flange of several grooves including nut body and surface, the flange is set as inclined surface backwards to nut body on one side, it is front end that the nut body, which has flange one end, one end opposite with flange is rear end, the inclined direction of the inclined surface is that ecto-entad moves closer to front end, the utility model is when in use, after nut tightening, elastic deformation can occur for flange, the acting surface increase of upper groove contact product of making to offer reaches anti-skidding purpose, simultaneously in vibration, elastically-deformable flange occurs being capable of automatic compensation vibration bring gap, prevent to loosen.

Description

Anti-skidding flange nut

Technical field

The utility model belongs to nut field, more specifically to a kind of anti-skidding flange nut.

Background technique

Flange nut, also referred to as band pad nut, flower teeth nut, hexagon nut with flange, flange nut etc..It is used in pipeline mostly It connects or needs to increase on the workpiece of nut contact surface.

Flange nut generally includes the face-flange that nut body is fixedly connected with side at present, in flange backwards to nut sheet The side of body is that groove can be also arranged in enhancing skid resistance, and when in use, the acting surface of groove contact product increases skid resistance, tooth Line directly contacts firmly with the acting surface of product, in vibration, can still occur to loosen situation.

Utility model content

In view of the deficiencies of the prior art, the utility model provides one kind when in use, and after nut tightening, flange can be sent out The acting surface increase of raw elastic deformation, the upper groove contact product that makes to offer reaches anti-skidding purpose, while in vibration, elasticity occurs The flange of deformation can automatic compensation vibration bring gap, prevent the anti-skidding flange nut loosened.

To achieve the above object, the utility model provides following technical solution: a kind of anti-skidding flange nut, including nut Ontology and surface have the flange of several grooves, and the flange is set as inclined surface, the nut backwards to nut body on one side It is front end that ontology, which has flange one end, and one end opposite with flange is rear end, and the inclined direction of the inclined surface is ecto-entad Move closer to rear end.

At least one telescopic chute is offered on the further flange, the telescopic chute is extended outside to inside by flange.

Groove side, which is corresponded to, on the further flange is provided with rubber ring.

Compared with prior art, the utility model has the beneficial effects that the outermost of flange contacts first when nut tightening The acting surface of product, as nut continues to screw, elastic deformation occurs for flange, to flat direction deformation, i.e., the inside of flange by The acting surface of product is gradually also touched, guarantees the contact area of the acting surface of groove and product, reaches anti-skidding purpose, and is being occurred When vibration, flange elastically-deformable first will absorb vibrational energy, and nut and product is avoided to relatively move, if nut and product it Between generate gap, elastically-deformable flange, which occurs, automatically to be compensated gap, rotated after preventing nut from loosening, wherein Rubber ring further enhances anti-skidding and slowing down vibration bring negative condition.

Specific embodiment

It is described further referring to figs. 1 to embodiment of the Fig. 3 to the anti-skidding flange nut of the utility model.

A kind of anti-skidding flange nut has the flange 2 of several grooves 3, the flange 2 including nut body 1 and surface It is set as inclined surface on one side backwards to nut body 1, it is front end 12 that the nut body 1, which has 2 one end of flange, opposite with flange 2 One end be rear end 11, the inclined direction of the inclined surface is that ecto-entad moves closer to rear end 11, i.e., is placed in 2 face of flange When on horizontal plane, the outer ring exposure level face of flange 2, and flange 2 extended internally by outer ring it is more and more remoter apart from horizontal plane.

As shown in figure 3, inclined surface and plane angle are b, b is preferably 4-7 degree, and groove 3 and flange 2 are same, two Person is in parastate, i.e. groove 3 and plane is also in angle b.

In use, rotating nuts ontology 1, the outmost turns of flange 2 are by the acting surface of contact product first, with gradually revolving Tightly, the outmost turns of flange 2 will deformation occurs, and the acting surface of product is come into contact with close to the part of inner ring, i.e., groove 3 contacts Product is gradually increased the area of 3 contact product of groove, enhances non-skid property, when vibrating, elastically-deformable flange 2 Vibration can be absorbed, prevents from loosening.

The present embodiment preferably offers at least one telescopic chute 4 on the flange 2, and the telescopic chute 4 is export-oriented by flange 2 Interior extension, telescopic chute 4 is more easier to make quotation, and deformation occurs, and elastic property is more.

Preferably correspond to 3 side of groove on the flange 2 is provided with rubber ring 5 to the present embodiment, as shown in Fig. 2, rubber ring 5 It is preferably in the middle position of every groove 3, when nut body 1 is torqued-up to a certain degree, rubber ring 5 just starts contact and produces The acting surface of product, rubber ring 5 enhance non-skid property, while also having and absorbing vibration, cooperate with flange 2, further Enhance anti-skidding and vibrationproof performance.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.

Claims
