Abstract

The utility model discloses a kind of drum type self-plugging rivets, including rivet body and combine in tandem in the intracorporal blind rivet of the riveting, the blind rivet is made of the head of a nail, ailhead and blind rivet body, the ailhead and head of a nail connection place are provided with several continuous pawls, the ailhead and blind rivet body connection place are provided with stop edge, along the riveting shell step being provided with stop edge cooperation in the rivet body pull side, stop edge is stuck at riveting shell step after staking.The utility model increases pawl and stop edge in blind rivet, the upsetting riveting shell step on rivet body, stop edge can be stuck at step after guaranteeing staking, so that the double combinations of stop edge and riveting shell step effectively prevent the phenomenon that blind rivet can loosen in workpiece by rivet body and pawl.

Description

A kind of drum type self-plugging rivet

Technical field

The utility model relates to a kind of riveting parts fields of fixing component, and in particular to a kind of drum type self-plugging rivet.

Background technique

Become with the development of science and technology, drum type rivet will not generate expansion to workpiece hole by its high-tensile high shear force The advantages of shape, gradually instead of traditional open-type rivet, being put with especially light in automobile fitting, rail traffic.But it is this The ailhead of rivet is that ailhead by riveting shell packs tightly difference outside riveting shell, and after traditional rivet staking, therefore when being easy because breaking Reaction force, which occasionally results in blind rivet, the phenomenon that slight rebound loosens, and issues abnormal sound so as to cause since riveting parts vibrate.

Utility model content

In view of the above-mentioned problems, the utility model is intended to provide a kind of drum type self-plugging rivet.

To realize that the technical purpose, the embodiment of the utility model be: a kind of drum type self-plugging rivet, including rivet body and combination string Mounted in the intracorporal blind rivet of the riveting, the blind rivet is made of the head of a nail, ailhead and blind rivet body, the ailhead and head of a nail connection place Several continuous pawls are provided with, the ailhead and blind rivet body connection place are provided with stop edge, edge in the rivet body pull side It is provided with the riveting shell step with stop edge cooperation, stop edge is stuck at riveting shell step after staking.

Preferably, the rivet body pressed end periphery is equipped with thread rolling slot.

Preferably, the pawl is annular protrusion, the outer diameter of each pawl shape annular protrusion increases along the direction of extrusion.

The utility model has the beneficial effects that

1) increase pawl and stop edge in blind rivet, the upsetting riveting shell step on rivet body guarantees after staking that stop edge can be with It is stuck at step, so that the double combinations of stop edge and riveting shell step effectively prevent blind rivet in workpiece by rivet body and pawl In the phenomenon that loosening.

2) assembly technology for improving riveting shell and blind rivet pawl, avoids ailhead from loosening, prevents blind rivet from springing back.

Specific embodiment

The utility model is described in further details in the following with reference to the drawings and specific embodiments.

As shown in figures 1 and 3, specific embodiment described in the utility model are as follows:

A kind of drum type self-plugging rivet, including rivet body 1 and combine it is in tandem in the intracorporal blind rivet 2 of the riveting, the blind rivet by The head of a nail 21, ailhead 22 and blind rivet body 23 are constituted, the ailhead 22 and 21 connection place threading of the head of a nail be machined with it is several it is continuous fall Stop edge 6 is produced in tooth 5, the ailhead 22 and the 23 connection place upsetting of blind rivet body, and when riveting, the backward extrusion pressure of workpiece 3 squeezes rivet body 1 In the gap for entering pawl 5, rivet body 1 and pawl 5 are compressed, pawl 5 is preferably annular protrusion, outside each pawl shape annular protrusion Diameter increases along the direction of extrusion, is connected and fixed even closer.

Along the riveting shell step 7 cooperated with stop edge 6 is provided in 1 pull side of rivet body, stop edge 6 is stuck in after staking At riveting shell step 7, stop edge 6 completes combination by special caulking gun pipette tips and riveting shell step 7, and ailhead 22 is avoided to loosen, and prevents Non-magnetic shim core 23 is sprung back, and further avoids the phenomenon that blind rivet can loosen in workpiece.

The 1 pressed end periphery of rivet body be equipped with thread rolling slot 8, rivet body 1 riveting when, rapidly deformation, distending, along thread rolling 8 position of slot has folded drum and has acted on up to riveting.

The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, all according to this The technical spirit of utility model any trickle amendment, equivalent replacement and improvement to the above embodiments should be included in this Within the protection scope of utility model technical solution.
