The technical solution adopted by the utility model for solving the technical problems is as follows:
the inner locking type extruded and expanded all-aluminum rivet plug consists of a rivet rod and a plug cap, wherein the rivet rod consists of a pull rod and a rivet head positioned at the front end part of the pull rod, a fracture is formed at the joint of the rivet head and the pull rod, an inner locking concave ring is arranged above the fracture at the lower side of the rivet head, the plug cap is hollow and annular, a step convex ring is arranged at the inner side of the plug cap, and the plug cap is sleeved on the rivet rod.
Preferably, the rivet rod and the plug cap are made of aluminum materials.
Preferably, the diameter of the upper ring opening of the inner locking concave ring is larger than that of the lower ring opening.
Preferably, the inner diameter of the step convex ring is larger than the diameter of the lower ring opening of the inner locking concave ring and smaller than the diameter of the upper ring opening of the inner locking concave ring.
Preferably, a cup-shaped groove is formed at the upper end of the rivet head of the rivet rod.
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. in the process of riveting and plugging, the step convex ring at the inner side of the plug cap is extruded into the inner locking concave ring of the rivet head under the action of the riveter, so that the rivet head of the rivet rod is firmly locked in the plug cap, 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 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.
