Description

A kind of riveting nut and have the coupling arrangement of this riveting nut

Technical field

The utility model relates to a kind of riveting nut and has the connection set of this riveting nut.

Background technique

As shown in Figure 1, existing motorcycle ignition switch lock 100 and supporting 200 are coupled to each other by the screw attachment device, specifically, as can be known from Fig. 1, be with screw 300 with firing switch lock 100 with support 200 fixed to one another linking up.Though do like this and install more conveniently, be easy to stolen.Although also cooperate this structure to use many burglar-proof mechanisms, its effect is not ideal.

The model utility content

The purpose of this utility model is at the deficiencies in the prior art, a kind of riveting nut is provided and has the coupling arrangement of riveting nut, can with the motorcycle ignition switch lock and supporting is stable connects, and himself is simple in structure, installs easy and can play antitheft effect.

To achieve these goals, the utility model provides a kind of riveting nut, this riveting nut comprises bottom and cap, the two size shape is corresponding, fastens riveting each other, forms in its junction to connect the edge, bottom and cap riveting also are enclosed to form a space, this bottom is made of an above shell fragment, and shell fragment is from connecting along the central direction setting to the bottom, a described above shell fragment ora terminalis surrounded is shaped as circle.

To achieve these goals, the utility model also provides a kind of coupling arrangement that has riveting nut, this device comprises a rivet, rivet passes coupled object, the sheathed riveting nut of rivet end, rivet and riveting nut are fixedly connected coupled object, this riveting nut comprises bottom and cap, and the size shape of the two is corresponding, fastens riveting each other, form the connection edge in its junction, bottom and cap riveting also are enclosed to form a space, and this bottom is made of an above shell fragment, and shell fragment is from connecting along the central direction setting to the bottom, a described above shell fragment ora terminalis surrounded is shaped as circle, this circular diameter is less than the diameter of rivet.

In order to make connection more firm, be set between the riveting nut of rivet end and the coupled object and also be provided with rubber washer.

In sum, this riveting nut provided by the utility model and have the coupling arrangement of riveting nut can connect coupled object is stable, and himself is simple in structure, installs easily and can play antitheft effect, and cost is low, and is practical.

Embodiment

Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.

In conjunction with Fig. 2, shown in Figure 3, be respectively the utility model riveting nut structural representation and generalized section.From Fig. 2, Fig. 3 as can be known, the utility model provides a kind of riveting nut 1, this riveting nut 1 comprises bottom 11 and cap 12, the two size shape is corresponding, fastens riveting each other, forms in its junction to connect along 13, bottom 11 and cap 12 rivetings also are enclosed to form a space, this bottom 11 is made of an above shell fragment 111, and shell fragment 111 is from connecting along 13 11 the central direction settings to the bottom, a described above shell fragment 111 ora terminalis surrounded is shaped as circle.

As shown in Figure 4, be the connecting structure schematic representation of the utility model motorcycle ignition switch lock and supporting.As can be known from Fig. 4, be used to connect firing switch lock 100 and comprise with the coupling arrangement that supports 200, after riveting nut 1 and rivet 2, rivet 2 wore firing switch lock 100 and supported 200, the sheathed riveting nut 1 in its end was fixed.As shown in the figure, shell fragment 111 ora terminalis of this riveting nut 1 bottom 11 are constituted is shaped as circle, after guaranteeing that rivet 2 inserts riveting nut 1, shell fragment 111 can reset by elastic reaction and block rivet 2, thereby play antitheft effect, the diameter D of the circle that shell fragment 111 ora terminalis are constituted is less than the diameter of rivet 2.

In order to make connection more firm, be set between the riveting nut 1 of rivet 2 ends and the coupled object and also be provided with rubber washer 3.

In conjunction with Fig. 4 as can be known, coupling arrangement of the present utility model makes the existing screw connecting structure into the riveting connecting structure.Wherein, riveting nut 1 is the elastic reaction of the shell fragment 111 of utilization itself, and the bar portion 21 of rivet 2 is tightly blocked; The diameter D of shell fragment 111 is slightly less than rivet 1 diameter d.When needs install and fix, adopt special auxiliary mounting tool riveting bar 4 to finish, its structure is as shown in Figure 5.Adopt riveting bar 4 that riveting nut 1 is pressed into rivet 2, its shell fragment 111 pressurizeds curve inwardly, till being pressed onto rubber washer 3; Rubber washer 3 pressurized resiliences this moment move after making riveting nut 1 slightly, and shell fragment 111 resets by elastic reaction and blocks rivet, thereby plays antitheft effect.

Need to prove at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
