Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a riveting fastener. Background Technology

[0002] Riveting fasteners are fastening devices that permanently connect two or more components together using riveting technology. Riveting is a traditional connection method that is widely used in aviation, automotive, shipbuilding, construction and other fields.

[0003] Existing riveting fasteners involve placing rivets into the riveting holes of multiple plates, pulling the rivets with a riveting tool, and using a pusher block at the bottom of the rivet to compress the bottom of the rivet, causing deformation and securing the plates. However, because the deformation at the bottom of the rivet is relatively small, and the inner diameter of the riveting holes in the plates is large, the riveting fasteners are prone to loosening, affecting the riveting effect. In view of this, this solution proposes a riveting fastener to solve the above problems. Utility Model Content

The fastening cylinder 1 and the connecting cylinder 2 are inserted into the pre-reserved riveting holes of the plate. The fastening rod 3 is pulled by the riveting tool, and the fastening rod 3 drives the pushing part to move. The pushing part pushes the fastening mechanism, causing the fastening mechanism to deform, thereby riveting and fixing multiple plates. The Promotion Department includes: Connecting rod 12, one end of which is fixedly connected to the end of fastening rod 3 away from connecting cylinder 2; The movable rod 10 has one end fixedly connected to the end of the connecting rod 12 away from the fastening rod 3, and the end of the movable rod 10 away from the connecting rod 12 is slidably inserted into the end of the extrusion cylinder 5 away from the fastening plate 4. Push block 11, one end of push block 11 is fixedly connected to the end of moving rod 10 near the bottom of extrusion cylinder 5, and the end of push block 11 near moving rod 10 is slidably connected to the bottom of extrusion cylinder 5; It should be noted that the connecting rod 12 is fixedly installed at the end of the fastening rod 3 away from the connecting cylinder 2. The end of the connecting rod 12 away from the fastening rod 3 is fixedly connected to the moving rod 10. The end of the moving rod 10 away from the connecting rod 12 is fixedly connected to the pushing block 11. The end of the pushing block 11 near the moving rod 10 is slidably connected to the bottom of the fastening mechanism. The fastening cylinder 1 and the connecting cylinder 2 are inserted and connected to the pre-reserved riveting holes of the plate. The fastening rod 3 is pulled by the riveting tool, which drives the connecting rod 12 to move. The connecting rod 12 drives the moving rod 10 to move. The moving rod 10 drives the pushing block 11 to move, so that the pushing block 11 pushes the fastening mechanism, causing the fastening mechanism to deform, thereby riveting and fixing multiple plates. After the riveting is completed, the fastening rod 3 and the connecting rod 12 are separated by the riveting tool. In embodiment two, the present invention provides a locking mechanism, which is applied to a riveting fastener in embodiment one. The fastening mechanism is located at the end of the connecting cylinder 2 away from the fastening cylinder 1. The fastening mechanism includes a fastening part and a pressing part. The fastening part is fixedly connected to the end of the connecting cylinder 2 away from the fastening cylinder 1, and the pressing part is fixedly connected to the end of the fastening part away from the connecting part. The pressing part is used to press the fastening part to bend.

[0021] Specifically, the fastening part includes fastening plates 4, one end of each of the multiple fastening plates 4 is fixedly connected to the end of the connecting cylinder 2 away from the fastening cylinder 1, the other end of each of the multiple fastening plates 4 is fixedly connected to the extrusion part, and the inner wall of each of the multiple fastening plates 4 is provided with bending grooves 7. Specifically, the extrusion section includes an extrusion cylinder 5. One end of the extrusion cylinder 5 is fixedly connected to the end of a plurality of fastening plates 4 away from the connecting cylinder 2. A pushing part is slidably inserted at the end of the extrusion cylinder 5 away from the fastening plates 4. The pushing part is used to push the extrusion cylinder 5 to move. It should be noted that one end of multiple fastening plates 4 is fixedly connected to the end of the connecting cylinder 2 away from the fastening cylinder 1, and the end of multiple fastening plates 4 away from the connecting cylinder 2 is fixedly connected to the extrusion cylinder 5. The fastening cylinder 1 and the connecting cylinder 2 are inserted and connected to the pre-reserved riveting holes of the plate. The fastening rod 3 is pulled by the riveting tool, which drives the connecting rod 12 to move. The connecting rod 12 drives the moving rod 10 to move. The moving rod 10 drives the pushing block 11 to move, so that the pushing block 11 pushes the extrusion cylinder 5. The extrusion cylinder 5 moves to extrude the fastening plate 4. Through the cooperation of the extrusion cylinder 5 and the bending groove 7, the fastening plate 4 is deformed due to the extrusion action, and the fastening plate 4 is bent at the bending groove 7. This causes the outer wall of the fastening plate 4 to fit with the surface of the plate, so that the fastening plate 4 can rivet and fix multiple plates. Specifically, a plurality of reinforcing blocks 6 are fixedly installed on the outer wall of one end of the fastening plate 4 near the connecting cylinder 2. The reinforcing blocks 6 are used to reinforce the connection between the fastening plate 4 and the plate. It should be noted that multiple reinforcing blocks 6 are fixedly installed on the outer wall of the end of the fastening plate 4 away from the connecting cylinder 2. When the extrusion cylinder 5 causes the fastening plate 4 to deform, the reinforcing blocks 6 are made to fit against the surface of the plate through the bending of the fastening plate 4. The reinforcing blocks 6 increase the friction between the fastening plate 4 and the surface of the plate, and prevent the fastening plate 4 from loosening and affecting the riveting effect. A fixing plate 8 is fixedly installed on the top of the fastening cylinder 1, and the fixing plate 8 is slidably sleeved with the fastening rod 3; Furthermore, an elastic block 9 is fixedly installed at one end of the fixing plate 8 near the fastening cylinder 1, and the end of the elastic block 9 away from the fixing plate 8 is fixedly connected to the surface of the plate. It should be noted that the fixing plate 8 is fixedly installed on the top of the fastening cylinder 1, and the fixing plate 8 is slidably sleeved with the fastening rod 3. The elastic block 9 is fixedly installed on one end of the fixing plate 8 near the fastening cylinder 1. The fastening cylinder 1 and the connecting cylinder 2 are inserted and connected to the pre-reserved riveting holes of the plate, so that the fixing plate 8 is in contact with the surface of the plate, and then the elastic block 9 is in contact with the surface of the plate. After the plate is riveted by the fastening plate 4, the fixing plate 8 squeezes the elastic block 9. The elasticity of the elastic block 9 generates a reaction force, which enhances the tightness between the fastening plate 4 and the plate and improves the riveting effect.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
