Abstract

The utility model relates to a simple rivet, which is composed of a rivet body and a rivet rod. The upper end of the rivet body having inner holes is provided with a flange, the lower part is provided with grooves communicated with the inner holes and uniformly distributed by the circumference, an elastic petal is formed, the rivet rod is provided with a cover cap and a rod part, and the diameter of the rod part is mutually matched with the interference of the inner holes of the rivet body. Compared with the existing rivet, the connection for the rivet is quick, and a simple tool or manual press can be used for realizing riveted connection. Materials with strong plasticity can be adopted to manufacture the utility model, the utility model can also be dismounted to reuse, the appearance is beautiful, and the utility model is suitable for the connection of the riveted connection of thinner parts.

Description

Simple rivet

The utility model relates to connector element, particularly the connector element of thin-walled parts.

Rivet is the connector element commonly used that connects two or two above parts, in general, but be connected the two-sided tool using of part, available hammering rivet, if can only the single face tool using, use self-plugging rivet mostly, it is non-disconnectable that above-mentioned rivet connects the back, connects the formality trouble, also needs special tool(s) to rivet as self-plugging rivet, cost is higher, and the surface is not attractive in appearance.

The purpose of this utility model is to avoid the defective of prior art and provides a kind of connection quick, the Simple rivet of detachable repeated use, beautiful shape.

The utility model is achieved in that Simple rivet is made of rivet body and rivet rod, rivet body upper end with endoporus has flange, bottom to have the groove that communicates with endoporus of circumference uniform distribution, forms the elasticity lobe, rivet rod has cap and bar portion, and bar portion diameter and the interference of rivet body endoporus match.

The utility model compared with prior art connects fast, and available simple tool or hand if adopt the strong material of plasticity to make, are gone back detachable the repeated use by the realization riveted joint, and surface aesthetic.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is that the A of Fig. 1 is to view.

Fig. 3 is the phase diagram after riveting.

Elaborate again in conjunction with above-mentioned accompanying drawing.

As Figure 1-3, Simple rivet is made of rivet body (3) and rivet rod (1).

Rivet body (3) has endoporus, and the endoporus interior edge face is a chamfer surface, and there is flange the upper end, inserts when being connected part and can play position-limiting action, and the bottom has the groove (5) that the 3-5 bar of circumference uniform distribution communicates with endoporus, and the groove of present embodiment is 4, forms 4 spring lobes (4).

Rivet rod (1) has cap and bar portion (2), and bar portion diameter and the interference of rivet body endoporus match, and cap be for containing the concave inward structure of rivet body (3) flange, makes the rivet body flange after the riveted joint topped by the rivet rod cap.Rivet rod easily inserts rivet body when riveting in order to make, and bar portion (2) lower end of rivet rod can adopt bulb or nose cone or many ribs header structure.After rivet rod inserts rivet body, elasticity lobe (5) be subjected to bar portion squeeze power and to around open and reach the connection purpose.

The thin-walled parts that the utility model generally is used for more than two or two connects, when the less demanding part of riveting intensity, can adopt stronger material of plasticity such as plastics Manufacturing material as rivet, because material has stronger plasticity, after tripping out rivet rod (1), elasticity lobe (4) on the rivet body can restore, reusable, this rivet can replace the tapping screw union piece, and it is beautiful shape not only, and can not get rusty, operate also much simple than tapping screw, general diameter is no more than 10 millimeters hole, can both not need any instrument with hand by entering.

During for the demanding part of riveting intensity, can adopt metallic material to make, as iron, copper and aluminium etc., at this moment because material plasticity is low, trip out rivet rod (1) back rivet body elasticity lobe and can not restore automatically, the part that generally is used for permanent riveted joint connects, and can replace self-plugging rivet to use, but it is much simple that instrument is wanted, as long as general iron hammer is knocked in.

Claims

1. a Simple rivet is characterized in that being made of rivet body (3) and rivet rod (1), and there is flange the rivet body upper end with endoporus, the bottom has the groove that communicates with endoporus (5) of circumference uniform distribution, form elasticity lobe (4), rivet rod has cap and bar portion (2), and bar portion diameter and the interference of rivet body endoporus match.

2. Simple rivet as claimed in claim 1 is characterized in that described rivet body (3) endoporus has chamfer surface.

3. Simple rivet as claimed in claim 1 or 2 is characterized in that described rivet body (3) bottom has 3-5 bar groove (5), 3-5 elasticity lobe of corresponding formation (4).

4. Simple rivet as claimed in claim 1, the cap that it is characterized in that described rivet rod (1) is for containing the concave inward structure of rivet body (3) flange.

5. as claim 1 or 4 described Simple rivets, bar portion (2) lower end that it is characterized in that described rivet rod is bulb or nose cone or many ribs header structure.
