Description

Pin for press riveting nut

Technical Field

The utility model relates to the technical field of hardware processing, in particular to a pin for a press-riveting nut.

Background

The standard hexagonal press riveting nut consists of a baffle ring, a concave ring and a stud, wherein the baffle ring, the concave ring and the stud are integrally formed and form a screw hole penetrating through the baffle ring, the concave ring and the stud. The prior art has the following defects: the screw is the through-hole, and the screw front and back end can twist the screw respectively behind the riveting panel and carry out the installation of work piece, but because the screw is the through-hole so when screwing in two screws we hardly control the degree of two screw screwing in, the more dark another condition of screwing in of one screwing in can appear in the high probability, screws in more shallow one side and leads to the work piece pine easily.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a pin for a press-riveting nut.

The technical scheme of the utility model is as follows:

the utility model provides a press pin for riveting nut, it includes keeps off ring, concave ring, double-screw bolt, end plate and screw rod, keep off the ring front end and be provided with concave ring, concave ring front end is provided with the double-screw bolt, and the double-screw bolt front end is provided with the end plate, and the end plate front end is provided with the screw rod, keep off ring, concave ring and double-screw bolt are provided with a screw jointly.

Further, the baffle ring, the concave ring, the stud, the end plate and the screw are integrally formed, and the baffle ring, the concave ring, the stud, the end plate and the screw are made of free-cutting steel, so that the quick forming of a section is facilitated.

Furthermore, the baffle ring is hexagonal, the maximum diameter of the baffle ring is larger than the diameter of the stud, and the baffle ring needs to bear larger pressure when the plates are riveted, so that the pressure is reduced by increasing the area, and the baffle ring is prevented from being crushed during riveting.

Further, the outer surfaces of the baffle ring, the concave ring, the stud, the end plate and the screw are plated with environment-friendly color zinc layers, rust prevention and environment protection.

In some preferred embodiments, the front end of the end plate is provided with a grinding layer for improving friction between the screw and the end plate and the workpiece after the screw is connected with the workpiece in a threaded manner, so that the possibility of loosening is reduced.

In some embodiments, the front end face and the rear end face of the baffle ring are respectively provided with a sand grinding layer for improving friction force between the baffle ring and the plate and friction force between the baffle ring and the workpiece, so that the possibility of loosening is reduced.

In some embodiments, the concave ring is externally filled with a rosin layer. After the utility model is inserted into the mounting hole of the plate and before riveting, the utility model can easily shake on the plate due to the smaller outer diameter of the concave ring, and the shaking can lead the concave ring to continuously rub with the mounting hole of the plate, so that the plating layer can be scratched. The concave ring can be protected at the stage by arranging the rosin layer, and most of rosin can be liquefied and extruded out of the concave ring due to heat energy generated by instantaneous high pressure during riveting, so that the riveting cannot be influenced.

The beneficial effects of the utility model are as follows: 1. the fixed screw rod is arranged for replacing one screw rod, so that the number of screw rods can be reduced; 2. the end plate seals the tail end of the screw hole of the stud, and the depth of the screwed screw is limited, so that workpieces on two sides of the plate can be stably installed, the function and the shape of the plate are similar to those of pins, and other workpieces can be suspended and fixed on the plate.

fig. 2 is a schematic structural view of the present utility model.

In the figure, 1, a baffle ring; 2. a concave ring; 3. a stud; 4. an end plate; 5. and (3) a screw.

Detailed Description

The following is a further description of embodiments of the utility model, taken in conjunction with the accompanying drawings:

example 1

As shown in fig. 1 and 2, a pin for press riveting nuts comprises a baffle ring 1, a concave ring 2, a stud 3, an end plate 4 and a screw 5, wherein the concave ring 2 is arranged at the front end of the baffle ring 1, the stud 3 is arranged at the front end of the concave ring 2, the end plate 4 is arranged at the front end of the stud 3, the screw 5 is arranged at the front end of the end plate 4, and a screw hole is commonly arranged among the baffle ring 5, the concave ring 2 and the stud 3.

The baffle ring 1, the concave ring 2, the stud 3, the end plate 4 and the screw 5 are integrally formed.

The baffle ring 1 is hexagonal, and the maximum diameter of the baffle ring 1 is larger than that of the stud 3.

The outer surfaces of the baffle ring 1, the concave ring 2, the stud 3, the end plate 4 and the screw 5 are plated with environment-friendly colored zinc layers.

Example 2

The front end of the end plate 4 is provided with a sand grinding layer.

The front end face and the rear end face of the baffle ring 1 are respectively provided with a sand grinding layer. Other structures of this embodiment are the same as those of embodiment 1.

Example 3

And a rosin layer is filled outside the concave ring 2. Other structures of this embodiment are the same as those of embodiment 2.

The application method of the utility model comprises the following steps:

1) The utility model is inserted into the mounting hole of the plate, so that the concave ring is positioned at the mounting hole;

2) The utility model is riveted with the plate through riveting equipment, and the deformation of the plate enables the metal at the mounting hole of the plate to be pressed into the concave ring, thereby fixing the utility model;

3) One side of the baffle ring can be provided with a workpiece in a mode of screwing in a screw, and one side of the screw rod can be directly screwed with the workpiece.

The foregoing embodiments and description have been provided merely to illustrate the principles and best modes of carrying out the utility model, and various changes and modifications can be made therein without departing from the spirit and scope of the utility model as defined in the appended claims.
