Therefore, once an item is defined or described in one drawing, it will not be necessary to further specifically discuss and describe it in the description of subsequent drawings.

[0031] Before understanding the fastening nut in the embodiments of the present application, it should be clear that the fastening nut has a wide range of application scenarios, including industries such as energy, electronics, electrical appliances, machinery, chemical industry, metallurgy, molds, hydraulics, etc. It can be applied wherever fastening is required on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemical industry, meters, and supplies.

[0032] To solve the technical problems in the background art, as Figures 1-3 shown, the present application provides a technical solution: a thin - plate fastening nut, including:

[0033] The screw body 1 is composed of a screw head 2 and a screw rod 3. The screw rod 3 is provided with an external thread for mating with an internal thread. The riveting part 4 has a through - hole that accommodates the screw rod 3 passing through and is coaxially arranged with the screw body 1. This structural design is conducive to the tight combination of the screw body 1 and the riveting part 4. The upper gasket end 5 is arranged on the riveting part 4 and is an annular gasket, whose main function is to disperse pressure and protect the surface of the connecting piece. The sleeve 6 is arranged on the upper gasket end 5 and extends in a direction away from the screw head 2 for accommodating the screw rod 3 to pass through. One end of the out - spreading part 7 is connected to the upper gasket end 5, and the other end is connected to the lower gasket end 8, which is the main deformable part. A plurality of out - spreading parts 7 are arranged annularly along the outer side of the sleeve 6. The lower gasket end 8 is connected to the out - spreading part 7 to form a stable support structure. A ring 9 is arranged on the inner circle of the lower gasket end 8 and extends in the direction of the sleeve 6. The ring 9 is coaxially arranged with the sleeve 6. The ring 9 is provided with an internal thread adapted to the screw rod 3 to ensure that the screw rod 3 can be smoothly screwed in. This design helps to improve the stability of the thin - plate fastening nut during the fastening process and prevent the nut from displacing during use.

[0034] During use, place the thin - plate fastening nut into the through - hole of the fixing plate of the workpiece to be fastened. Use a tool to press the upper gasket end 5, insert the screw body 1 into the through - hole of the riveting part 4, and screw it spirally until the screw head 2 is close to the upper gasket end 5. Press the screw body 1 to keep the screw head 2 close to the upper gasket end 5, and use a tool to unscrew the screw body 1. At this time, under the action of the thread, the ring 9 rises. The lower gasket end 8 and the out - spreading part 7 rise under the action of the ring 9. When the displacement reaches a certain degree, the out - spreading part 7 deforms and folds. When the ring 9 is close to the upper gasket end 5, the out - spreading part 7 completes the deformation. At this time, the out - spreading part 7 and the upper gasket end 5 jointly clamp the fixing plate of the workpiece to be fastened to complete the fixation. At this time, unscrew the screw head 2, place the workpiece to be fastened, and then screw the screw head 2 onto the riveting part 4 again to complete the fixing action of the workpiece to be fastened.

[0035] Furthermore, the abduction part 7 has an arcuate outwardly protruding surface, and its shape is more conducive to deformation during the process of being compressed and stressed. The abduction part 7, as the main component for force-induced deformation, if the initial state is set to be outwardly protruding, its deformation can be completed simply by manpower or using simple tools. Especially when applied to thin plates, excessive external force is likely to cause deformation of the thin plates.

[0036] It should be noted that the abduction part 7 specifically includes an upper sheet body 10 and a lower sheet body 11. Both the upper sheet body 10 and the lower sheet body 11 are in the shape of a flat plate. The waist constriction 12 is located between the upper sheet body 10 and the lower sheet body 11. The upper sheet body 10, the lower sheet body 11, and the waist constriction 12 are integrally formed. The width of the waist constriction 12 is smaller than the widths of the upper sheet body 10 and the lower sheet body 11. In order to further improve the force-induced deformation efficiency of the abduction part 7, a waist constriction 12 is added.

[0037] Furthermore, in order to improve the stability during final fastening, a connecting platform 14 is provided between the lower sheet bodies 11. After being stressed and deformed, the connecting platform 14 can expand outward, increasing the force-bearing area of the lower gasket end 8 and also increasing the connecting area between multiple abduction parts 7, preventing the abduction part 7 from being overly deformed and causing uneven stress.

[0038] It should be noted that the height of the connecting platform 14 is smaller than the height of the ring 9. As an additional protective component of the lower sheet body 11, although a too-high connecting platform 14 can play a good protective role, it is not conducive to the deformation of the abduction part 7. Moreover, further, if the connecting platform 14 is higher than or equal to the height of the ring 9, it is not conducive to the ring 9 being sleeved into the sleeve 6.

[0039] Furthermore, the outer diameter of the ring 9 is smaller than the inner diameter of the sleeve 6. When the riveting part 4 is squeezed, the ring 9 can be sleeved into the sleeve 6. The ring 9, as the main force-bearing component for threaded connection, after the thin plate fastening nut is stressed, dropping the ring 9 into the sleeve 6 can not only protect the sleeve 6, but also disperse the force-bearing points of the ring 9 and protect the ring 9. It strengthens the firmness of the thin plate fastening nut. At the same time, it is thinner after deformation, occupies less volume, and is conducive to the subsequent connection between workpieces.

[0040] It should be noted that the upper gasket end 5, the sleeve 6, the abduction part 7, the lower gasket end 8, and the ring 9 are integrally formed. The riveting part 4, as an important component of this thin plate fastening nut, its main function is to achieve connection with other components. The design of the riveting part 4 ensures the stability and reliability of the connection and avoids structural failure caused by connection problems. The main role of the upper gasket end 5 is to provide support during the connection process and reduce damage to other components caused by excessive connection force.

[0041] Furthermore, the upper sheet body 10 is narrower than the lower sheet body 11. After being stressed, the upper sheet body 10 and the lower sheet body 11 deform in opposite directions and finally approach each other. Since the lower sheet body 11 presses on the upper sheet body 10 after being stressed, when finally riveting the workpiece to be processed, the lower sheet body 11 is stressed. Therefore, the area of the lower sheet body 11 is set to be wider than that of the upper sheet body 10. As a deformation component, the upper sheet body 10 with an appropriate width is more conducive to completing the deformation.

[0042] It should be noted that the upper gasket end 5 has a concave cavity 15. The concave cavity 15 is circular, with a diameter slightly smaller than the diameter of the upper gasket body, and the depth of the concave cavity 15 is appropriate to ensure that during the installation process, after the ring 9 can smoothly enter the sleeve 6, they are both located in the concave cavity 15. The specific dimensions of the concave cavity 15 can be adjusted according to actual application requirements. The concave cavity 15 is beneficial to improving the matching accuracy between the ring 9 and the sleeve 6, ensuring the installation stability, and extending its service life.

[0043] Furthermore, it also includes a protrusion 13. The protrusion 13 is provided on the upper surface of the upper gasket end 5. The shape of the protrusion 13 is cylindrical or spherical, with a height of about 1 / 3 to 1 / 2 of the thickness of the upper gasket end 5, and the diameter is determined according to the use requirements. The material of the protrusion 13 is the same as that of the upper gasket end 5 to ensure the stability of the overall performance. The protrusion 13 is provided at this position, so that the upper gasket end 5 has better support performance during the pressing process. At the same time, multiple protrusions 13 together play an anti-slip role.

[0044] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
