A rotary rivet usually consists of two parts: a rivet and a nut. One end of the rivet has a cylindrical rod with a conical or spherical head, and the other end has a raised part for locking the nut. The nut is a part with a threaded inner hole, usually installed on the other side of the connected material. When in use, the rivet is inserted into the hole of the connected material, and then rotated by a rotary rivet gun or a rotary riveting machine to form a tight connection between the rivet head and the raised part of the rivet nut, thereby fixing the connected materials together.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a rotary riveting rivet structure, including a right side rod 1, a fixed plate 9 is fixedly connected to the left side of the inside of the right side rod 1, a polygonal groove 3 is provided in the middle of the left side of the fixed plate 9, and a card slot 4 is provided at the front and rear ends of the left side of the fixed plate 9, a threaded rod 6 is installed on the left side of the right side rod 1, and the front and rear ends of the right side of the threaded rod 6 are fixedly connected with buckles 7, and the buckles 7 are respectively engaged with the corresponding card slots 4, a fixed rod 5 is fixedly connected to the middle part of the right side of the threaded rod 6, and the right end of the fixed rod 5 is fixedly connected to a limiting block 8, and a stabilizing mechanism 2 is installed on the right side of the right side rod 1; the limiting block 8 is engaged with the polygonal groove 3;

[0028] Specifically, when the length and type of the spin-riveted rivet need to be adjusted, the operator needs to take the right-side rod 1 and the threaded rod 6 for alignment; the key to this step is to ensure that the axes of the two rods coincide to ensure the subsequent installation accuracy; after the alignment is completed, the operator needs to align the threaded rod 6 with the insertion buckle 7 of the right-side rod 1, and insert it into the slot 4 for engagement; in this process, the precise cooperation of the buckle 7 and the slot 4 plays a key role, and they can ensure the stable connection between the threaded rod 6 and the right-side rod 1; next, the fixing rod 5 and the limit block 8 need to be inserted into the polygonal groove 3 for fixation; the purpose of this step is to enhance the overall stability of the spin-riveted rivet and prevent it from loosening or falling off during use. The design of the polygonal groove 3 enables the fixing rod 5 and the limiting block 8 to be connected to the rotary rivet in a more stable manner, thereby improving the reliability of the entire structure. After completing the above steps, the splicing and installation process of the rotary rivet is completed. This design enables the rotary rivet to be installed with threaded rods 6 of different types and sizes, thereby adapting to different use environments. For example, in situations where a large tensile force needs to be endured, a threaded rod 6 with a longer length and a larger diameter can be selected to enhance the connection strength of the rotary rivet. In situations where space is limited, a threaded rod 6 with a shorter length and a smaller volume can be selected to meet the installation requirements. This high degree of flexibility and adaptability enables the rotary rivet to meet various complex and changeable use requirements.

[0029] Reference Figure 1 and Figure 3 The stabilizing mechanism 2 includes an external nail 206, which is installed on the outside of the right rod 1. The upper and lower ends of the external nail 206 are fixedly connected with a hollow block 201. The inner wall of the hollow block 201 is fixedly connected with a spring 203. The end of the spring 203 is fixedly connected with a sliding block 204. Both sides of the outer wall of the sliding block 204 are fixedly connected with sliders 205. Both sides of the inner wall of the hollow block 201 are provided with sliding grooves 202, and the sliders 205 are slidably connected with the corresponding sliding grooves 202 respectively; a suction cup 10 is installed on the left side of the sliding block 204; and an inclined surface 11 is provided on the right side of the sliding block 204;

[0030] Specifically, when the right rod 1 is inserted into the pre-set hole, a series of delicate mechanical actions are carried out; in this process, the sliding block 204 plays a key role; when it collides with the edge of the hole, the spring 203 immediately pulls the sliding block 204 to retract; this action cleverly utilizes the inclination angle of the inclined surface 11, so that the sliding block 204 can retract smoothly; while the sliding block 204 moves, it also drives the slider 205 to slide in the slide groove 202; this design not only ensures the stability of the movement of the sliding block 204, but also provides a stable movement trajectory for the sliding block 204. The invention provides a clear plan; when the sliding block 204 passes through the range of the hole, the potential energy of the spring 203 starts to play a role; it pushes the sliding block 204 to extend and effectively blocks the lower position of the object; this step ensures the stability of the rivet during installation and prevents the rivet from loosening or falling off; in addition, in order to ensure the stability after installation, the designers also cleverly added a suction cup 10; this device can absorb the bottom position of the object and provide additional support for the rivet; this double guarantee makes the installation of the rivet more stable and greatly improves the reliability of the connecting parts.

[0031] Reference Figure 1 and Figure 3 The external nail 206 is made of high-strength alloy steel; the two sliding blocks 204 are symmetrically designed;

[0032] Specifically, the high-strength alloy steel external nails 206 increase the overall strength of the structure, and the symmetrically designed sliding blocks 204 increase the stability after installation.

[0033] Working principle: when the length and type of the spin riveting rivet need to be adjusted, the right side rod 1 and the threaded rod 6 are taken for alignment, and the threaded rod 6 is taken for insertion into the right side rod 1, and the buckle 7 is inserted into the card slot 4 for engagement, and the fixing rod 5 and the limit block 8 are inserted into the polygonal groove 3 for fixation, thereby completing the splicing and installation process of the spin riveting rivet. Threaded rods 6 of different types and sizes can be installed to adapt to different use environments, thereby improving the functionality of the spin riveting rivet and meeting the needs of use. When using the spin riveting rivet, the right side rod 1 is pressed down and inserted into the pre-set hole. During the pressing process, the sliding block 204 collides with the hole. At the edge of the hole, the spring 203 pulls the sliding block 204 to retract, and retracts along the inclination angle of the inclined surface 11. When the sliding block 204 moves, it drives the slider 205 to slide in the slide groove 202, which is used for limiting the movement of the sliding block 204. At the same time, the movement trajectory of the sliding block 204 is planned. After the sliding block 204 passes through the range of the hole, the potential energy of the spring 203 pushes the sliding block 204 to extend, blocking the lower position of the object. When installing the rivet, the suction cup 10 adsorbs the bottom position of the object, which further increases the stability after installation and brings convenience to use.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
