Abstract

The utility model relates to a fastening device, in particular to a rivet, which comprises a rivet rod, wherein one end of the rivet rod is connected with a rivet cap; the rivet rod and the rivet cap are coaxially connected; and the rivet is characterized in that a limiting part is arranged along the axial direction of the other end of the rivet rod. According to the rivet, the other end of the rivet body away from the rivet cap is provided with the limiting part, so that various components can be excellently riveted together; the rivet has a simple structure; and the strength of riveting is not affected due to non-uniform stressing during riveting.

Description

A kind of rivet

Technical field

The utility model relates to a kind of securing means, relates in particular to a kind of rivet.

Background technique

The rivet kind is a lot, and commonly used have cup head, tack, sunk head rivet, self-plugging rivet, a semitubular rivet.They include the rivet body that an end is provided with the rivet cap, but they can affect owing to unbalance stress the intensity of riveted joint when being applied to the riveted joint occasion, and the end area of rivet is larger or less simultaneously, also can affect the riveted joint gap.

Therefore, be necessary to propose a kind of new rivet and solve the problems referred to above.

The model utility content

The purpose of this utility model is in order to solve the problems of the technologies described above, a kind of rivet to be provided, and it is simple in structure, has reduced the riveted joint gap, can well each parts be riveted together.

To achieve these goals, the utility model can be taked following technological scheme:

A kind of rivet, it comprises the rivet bar of an end connection rivet cap, described rivet bar is connected with rivet cap coaxial line, it is characterized in that the axial limited part that is provided with of the other end of described rivet bar.

As preferred implementation of the present utility model, rivet comprises that further described limited part is the columniform projection of the symmetrical excision forming of direction part of paralleling to the axis.

As preferred implementation of the present utility model, rivet further comprises the equal diameters of maximum diameter and the described rivet bar of described limited part.

As preferred implementation of the present utility model, rivet comprises that further described rivet cap is the cylindrical body that has chamfering away from an end of described rivet bar.

The beneficial effects of the utility model are: rivet of the present utility model, compared with prior art, be provided with limited part at the other end away from the rivet cap at the rivet body, can not only well be riveted together each parts, and simple in structure, can not be subject to unbalance stress and affect the intensity of riveted joint in when riveted joint.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the front view of preferred embodiment of the present utility model;

Fig. 2 is the side view of Fig. 1.

Embodiment

Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.

Preferred embodiment: as shown in Figure 1 and Figure 2, rivet comprises that the rivet bar 2 of an end connection rivet cap 1, described rivet bar 2 be connected coaxial line and connect with the rivet cap, the other end of described rivet bar 2 axially be provided with limited part 3.

Concrete, described limited part 3 is the columniform projections of the symmetrical excision forming of direction part of paralleling to the axis, in order better to carry out the installation between fastening piece.

Wherein, the equal diameters of the maximum diameter of described limited part 3 and described rivet bar 2, easy processing, and avoid workpiece to be damaged.

Concrete, described rivet cap 1 is the cylindrical body that has chamfering away from an end of described rivet bar 2, and easy processing is attractive in appearance and conveniently take.

This preferred embodiment in use, rivet can be screwed into object, can reduce gap between rivet and the object by limited part 3, and can not be subject to unbalance stress and affect the intensity of riveted joint when riveted joint, has protected the riveted joint workpiece not to be damaged.

Be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.

Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
