Preferably, the rivet rod and the plug cap are made of aluminum materials.
Preferably, the cross section of the external locking ring is splayed.
Preferably, the outer diameter of the outer locking ring is smaller than the inner diameter of the limiting convex ring.
Preferably, the inner diameter of the external locking ring is larger than or equal to the diameter of the pull rod.
Preferably, a cup-shaped groove is formed at the upper end of the rivet head of the rivet rod.
Preferably, the joint of the rivet head and the upper side of the external locking ring is in a contracted shape.
Preferably, the outer side of the plug cap is provided with sealing anti-slip teeth.
The beneficial effects achieved by adopting the technical proposal of the utility model are as follows:
1. under the combined action of the external locking ring and the limiting convex ring, the rivet head of the rivet rod is firmly locked in the plug cap, so that an integrated structure is formed between the rivet head of the rivet rod and the plug cap, and the leakage phenomenon between the rivet head and the plug cap is effectively avoided;
2. the sealing anti-slip teeth are arranged on the outer side of the plug cap, and after the riveting is completed, the sealing anti-slip teeth can be firmly embedded into the inner wall of the process hole, so that an integrated structure is formed between the plug cap and the process hole, and the leakage phenomenon between the plug cap and the process hole is effectively avoided;
3. the riveting rod and the plug cap are made of aluminum materials, so that ionization potential difference of the riveting rod and the plug cap due to different materials is eliminated, electrochemical corrosion is avoided, and the service life of the riveting plug can be effectively prolonged.
4. The cross section of the outer locking ring is manufactured to be splayed, and after the riveting plug is completed, the splayed outer locking ring can be firmly locked with the plug cap through the limiting convex ring, so that the riveting plug effect is effectively improved.
5. The cup-shaped groove is formed in the upper end of the rivet head of the rivet rod, so that the external extrusion tension is controllable when the rivet plug is performed, the rivet plug can be prevented from extruding and cracking the thin-wall hole, and the purpose of effectively protecting a workpiece is achieved.
