Abstract

A fastening product, especially a rivet, including a rivet head and a rivet shaft, the main points of which are: the rivet is a hollow structure with threads along the inner wall of the rivet. The utility model has the advantages that it can be applied to the connection of frequently disassembled or soft fasteners, to repair damaged threads, and can also be applied to the replacement of public and inch threads. Firm, not easy to loosen and easy to use.

Description

a rivet

Technical field:

The utility model relates to a fastening product, in particular to a rivet.

Background technique

At present, when ordinary rivets are riveted to fasteners with soft materials, due to their small expansion, if they are shaken violently, the drilled holes will easily become larger and cause the rivets to fall off. Because the base material is soft, it is not easy to make screw holes on the base material.

Utility model content

The purpose of the utility model is to provide a rivet, which can not only be used for the connection of frequently disassembled or soft fasteners, repair damaged threads, but also be used for the replacement of metric and inch threads. Firm, not easy to loosen and easy to use.

The technical solution to achieve the purpose of the utility model is: a rivet, including a rivet head and a rivet rod, which is unique in that the rivet is a hollow structure, and the inner wall of the rivet has threads.

Moreover, there is an annular groove between the rivet head and the rivet rod.

And the rivet head is polygonal.

And the rivet head is triangular.

Or the rivet head is quadrangular.

Or the rivet head is hexagonal.

The utility model has the advantages: 1. The rivet is a hollow structure, and the inner wall of the rivet has threads, which can be used as a screw hole on a base material with a softer material to improve the hardness of the internal thread or replace the thread at the damaged screw hole, and at the same time, it can realize , Replacement of British thread. 2. An annular groove is used between the rivet head and the rivet rod. After the rivet is pressed into the substrate, the substrate material at the rivet head is squeezed into the groove, which limits the axial movement of the rivet and plays a fastening role. 3. The rivet head is polygonal. After the rivet is pressed into the base material, the polygonal rivet head sinks into the base material, effectively preventing the rivet from rotating in the base material.

Description of drawings

Figure 1 is a sectional view of the rivet.

Figure 2 is a diagram of the state of use of the rivet.

Specific implementation method

Referring to Figures 1-2, the utility model will be further described below in conjunction with the embodiments.

A rivet provided by the utility model includes a rivet head 1 and a rivet rod 3 . It is unique in that the rivet is a hollow structure, and the inner wall 4 of the rivet has threads 5 .

The thread 5 on the inner wall 4 can be used as a screw hole on a base material with a softer material to improve the hardness of the internal thread or replace the thread at the damaged screw hole, and also can realize the replacement of metric and inch threads.

A further technical solution may be that there is an annular groove 2 between the rivet head 1 and the rivet rod 3 .

The annular groove 2 used between the rivet head 1 and the rivet rod 3, after the rivet is pressed into the substrate, the substrate material at the rivet head 1 is squeezed into the groove 2, which limits the axial movement of the rivet and plays a role in tightening. Solid effect (as shown in Figure 2).

And the rivet head 1 is polygonal.

After the rivet is pressed into the base material, the polygonal rivet head 1 sinks into the base material (as shown in FIG. 2 ), which effectively prevents the rivet from rotating in the base material.

Or the rivet head 1 is triangular

Or the rivet head 1 is quadrangular.

A further technical solution may also be that the rivet head 1 is in a hexagonal shape.

Claims (6)

1. A rivet, comprising a rivet head and a rivet stem, is characterized in that: the rivet is a hollow structure, and the inner wall of the rivet is threaded. 2. The rivet according to claim 1, characterized in that there is an annular groove between the rivet head and the rivet shaft. 3. The rivet according to claim 1 or 2, characterized in that the rivet head is polygonal. 4. The rivet according to claim 3, wherein the rivet head is triangular in shape. 5. The rivet according to claim 3, characterized in that the rivet head is quadrangular. 6. The rivet according to claim 3, wherein the rivet head is hexagonal.
