Anti-shock, anti-seepage, sealed folding type self plugging rivet

Abstract

This invention discloses a shock-proof, antiseep, closed type collapsible self plugging rivet. It includes rivet body and rivet core. The body is tubular structure, and there is radial evagination plat at its one end circle direction. There is radial deflection arch at one end of the core, the other end extend out from the no cover end and dent into rivet body and extend out the cover. Its feature is that there is annular tinajita along circumferencial direction on the body inside, and rubber seal ring is fixed in annular tinajita. There are several longitudinal continuous mangers on the body, they are same length and two ends same, they extend from cover inside to no cover end, and space is leaved to non cove end. The seal capability of this rivet is good, and it has shock-proof, antiseep function, so it can be not only used to rivet hard or thick work piece, but also to rivet soft or thin work piece, its application range is not restrict. It can be used to the fix of two or more than two work pieces.

Description

(1) Technical field [0001] The present invention relates to a fastener. Specifically, it is a shockproof, leakproof, sealed folding blind rivet used to fix two or more workpieces together. (2) Background technology [0002] At present, among the rivets used to rivet two or more workpieces together, open-type rivets are used the most. This type of open rivet consists of a nail body and a nail core, wherein the nail body is tubular, and one end has a radially outer boss used as a nail cover. One end of the nail core has a semicircular protruding head, and the other end of the nail core penetrates into the nail body from the end of the nail body without a radially outer boss. When the workpiece is riveted, the semicircular protruding head at one end of the nail mandrel is pulled into the nail body through the action of the riveting gun, so that the end of the nail body without the nail cover is stretched, so that the riveted workpiece is clamped by the stretched end and the n...

AI Technical Summary

Problems solved by technology

This kind of rivet has the following problems: one is that after the riveting, the rivet cover is directly in contact with the riveted workpiece, and the rivet is easy to loosen when subjected to collision or vibration, and the shockproof effect is poor; the other is that the nail cover directly contacts the riveted workpiece Hard-to-hard contact, there will inevitably be a gap between the nail cover and the riveted workpiece, and the sealing performance is poor

If it is used for riveting of soft or thin workpieces, it is not only difficult to rivet firmly, but also easy to damage the riveting holes of the workpiece

Therefore, this type of open rivet can only be used for riveting hard or thick workpieces, and cannot be used for riveting soft or thin workpieces, and the scope of application is limited.
