[0002] A riveting nut, also known as a blind riveting nut or a blind nut, as a special fastener, its composition may vary depending on specific designs and application scenarios.

[0003] During use, the riveting nut needs to be inserted into a reserved installation hole. At this time, an electric device is used to drive a screw rod to rotate into the riveting nut, so that the screw threads on the inner wall of the riveting nut are engaged. Until the end of the electric device abuts against the end of the riveting nut outside the body, if the electric device is continued to be turned on while the electric device and the screw rod cannot move further, it will drive the outer wall of part of the riveting nut to collapse, so that the collapsed part forms a ring with a larger diameter and abuts against the other side of the installation hole. At this time, the installation of the riveting nut is completed.

[0004] However, when installing a riveting nut on a metal plate with slightly lower structural strength such as an aluminum plate, since the riveting nut is inserted into a reserved installation hole, and the structural strength of the aluminum plate is slightly lower.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific implementation modes.

[0023] An embodiment of the present utility model discloses a riveting nut for metal plate reinforcement. As shown in the attached Figures 1-3 figure, it includes a nut sleeve 1 and a base 2. The base 2 is fixedly arranged at the end of the nut sleeve 1, and a fastening unit 3 is arranged at the connection between the nut sleeve 1 and the base 2;

[0024] The fastening unit 3 includes a plurality of fastening strips 31. The ends of the plurality of fastening strips 31 are fixedly connected to the outside of the end of the nut sleeve 1. Both sides of the fastening strip 31 are formed as arc surfaces 32, and an inclined surface 33 is formed above the fastening strip 31. Since both sides of the fastening strip 31 are formed as arc surfaces 32, it is easier for the fastening strip 31 to be embedded in the outside of the aluminum plate. At the same time, the inclined surface 33 is formed above the fastening strip 31, so that the connection is tighter after the fastening strip 31 is embedded in the outside of the aluminum plate.

[0025] During the use process, after inserting the nut sleeve 1 into the installation hole of the aluminum plate, the base 2 abuts against the outside of the aluminum plate. At this time, a screw is screwed into the nut sleeve 1, so that the end of the electric device abuts against the base 2. At this time, the electric device is continuously turned on, so that the nut sleeve 1 collapses. When the collapsed part of the nut sleeve 1 abuts against the other side of the aluminum plate, the electric device is continuously turned on, so that a plurality of fastening strips 31 at the connection between the nut sleeve 1 and the base 2 squeeze the outside of the aluminum plate until the plurality of fastening strips 31 are embedded in the outside of the aluminum plate, so that the connection between the nut sleeve 1 and the base 2 is tighter under the action of the plurality of fastening strips 31, thereby avoiding the situation that the nut sleeve 1 and the base 2 loosen relative to the aluminum plate.

[0026] Further, the nut sleeve 1 includes a hexagonal sleeve part 11 and a circular sleeve part 12. The two ends of the hexagonal sleeve part 11 are respectively connected to the base 2 and the end of the circular sleeve part 12.

[0027] By providing the hexagonal sleeve part 11 and the circular sleeve part 12, the installation hole on the aluminum plate is set as a hexagon. After inserting the hexagonal sleeve part 11 and the circular sleeve part 12 for installation, the hexagonal sleeve part 11 fits against the inner wall of the installation hole, so that there is no relative rotation.

[0028] Specifically disclosed, the minimum outer diameter of the hexagonal sleeve part 11 is greater than the outer diameter of the circular sleeve part 12.

[0029] Furthermore, it makes it more convenient and faster for the circular sleeve portion 12 to be inserted into the mounting hole on the aluminum plate.

[0030] Furthermore, a threaded groove 13 is provided between a part of the inner wall of the hexagonal sleeve portion 11 and the inner wall of the circular sleeve portion 12.

[0031] Through the provided threaded groove 13, on the one hand, it can be used for the installation between the hexagonal sleeve portion 11 and the circular sleeve portion 12 and the aluminum plate, and on the other hand, subsequent objects can be installed after the installation is completed.

[0032] Furthermore, another part of the inner wall of the hexagonal sleeve portion 11 is set as a crush section 14.

[0033] Specifically disclosed, a crush annular groove 15 is provided on the inner wall of the crush section 14.

[0034] Through the provided crush section 14 and crush annular groove 15, the crush section 14 can be accurately and quickly crushed.

[0035] Furthermore, the cross-section of the crush annular groove 15 is set as a triangle, so that the crush section 14 can be quickly crushed.

[0036] Furthermore, the cross-section of the fastening strip 31 gradually becomes smaller from the inside to the outside. The cross-section of the fastening strip 31 near one end of the hexagonal sleeve portion 11 is larger, so after being embedded in the aluminum plate, the contact area with the aluminum plate is larger and the connection is tighter. While the cross-section of the end of the fastening strip 31 far from the hexagonal sleeve portion 11 is smaller, which is convenient for being embedded in the aluminum plate.

[0037] During the use process, after inserting the nut sleeve 1 into the mounting hole of the aluminum plate, the base 2 abuts against the outer side of the aluminum plate. At this time, the screw is screwed into the nut sleeve 1 so that the end of the electric device abuts against the base 2. Then continue to turn on the electric device to make the nut sleeve 1 collapse. When the collapsed part of the nut sleeve 1 abuts against the other side of the aluminum plate, continue to turn on the electric device to make the multiple fastening strips 31 at the connection of the nut sleeve 1 and the base 2 squeeze the outer side of the aluminum plate until the multiple fastening strips 31 are embedded in the outer side of the aluminum plate, so that the connection between the nut sleeve 1 and the base 2 is tighter under the action of the multiple fastening strips 31, thereby avoiding the situation that the nut sleeve 1 and the base 2 become loose relative to the aluminum plate.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
