[0034] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.
[0035] like Figures 1-3 As shown, an embodiment of this utility model discloses a rivet-free automatic limiting nut, comprising a rotating nut 1 and a limiting buckle 2. The limiting buckle 2 has a limiting groove 21, and the rotating nut 1 is rotatably connected to the limiting groove 21. The limiting buckle 2 has a limiting hole 22. The rotating nut 1 comprises a nut body 11, a rotating structure 12, and a rotating shaft 13, which together constitute the core of the rotating nut 1. The nut body 11 is used to mate with the threaded portion of the screw 3. The rotating structure 12 provides the necessary rotational friction during rotation, while the rotating shaft 13 connects the nut body 11 to the limiting groove 21. The nut body 11 is fixedly connected to the rotating structure 12, one end of the rotating shaft 13 is fixedly connected to the nut body 11, and the end of the rotating shaft 13 away from the nut body 11 is rotatably connected to the limiting groove 21, ensuring the stability of the nut during rotation and preventing loosening or falling off due to rotation. This embodiment of the rivet-free automatic limiting nut eliminates the dependence on riveting tools, making the installation process simpler and faster. Users simply need to combine the rotating nut 1 with the limiting buckle 2, then pass the screw 3 through the limiting hole 22 and rotate it to achieve a tight connection. Since the rotating nut 1 can rotate freely within the limiting groove 21, it can adapt to installation requirements at different angles and directions, improving connection flexibility. This also reduces material and processing costs, improves production efficiency, and thus lowers overall costs.
[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: the rotating structure 12 includes at least one inclined surface, which is inclined downward from the direction close to the nut body 11 to the direction away from the nut body 11. This allows the screw 3 to automatically slide along the inclined surface and guide the rotating nut 1 to start rotating when it is inserted into the limiting hole 22 and contacts the rotating structure 12, reducing the need for manual adjustment and positioning during installation and improving installation efficiency and accuracy. Specifically, in this embodiment, the rotating structure 12 includes two inclined surfaces, which are symmetrically arranged about the nut body 11 as an axis, which helps to disperse the impact force of the screw 3 on the rotating structure 12 and reduce wear and fatigue caused by long-term stress.
[0037] As a preferred embodiment of the utility model, it can also have the following additional technical features: the limiting buckle 2 includes a limiting plate 23 and a connecting plate 24, the limiting plate 23 is fixedly connected with the connecting plate 24, the limiting hole 22 is arranged on the limiting plate 23, and the limiting groove 21 is arranged on the connecting plate 24. The limiting plate 23 is responsible for providing the limiting hole 22 for accommodating the screw 3, and the connecting plate 24 is responsible for providing the limiting groove 21 for connecting with the rotating shaft 13 of the rotating nut 1. By fixedly connecting the limiting plate 23 and the connecting plate 24, a more solid overall structure can be formed, which helps to enhance the deformation resistance and durability of the limiting buckle 2, and ensures that it can maintain stable performance during long-term use.
[0038] As a preferred embodiment of the utility model, it can also have the following additional technical features: the limiting plate 23 and the connecting plate 24 are arranged perpendicularly. The perpendicularly arranged limiting plate 23 and connecting plate 24 can form a more stable structure, which helps to enhance the overall stability of the connection and prevent the nut from twisting or loosening during rotation due to uneven stress.
[0039] As a preferred embodiment of the utility model, it can also have the following additional technical features: the connecting plate 24 is provided with two, the limiting hole 22 is arranged between the two connecting plates 24, and the two connecting plates 24 are arranged symmetrically about the limiting hole 22. A more stable support structure is formed, which helps to prevent the nut from deflecting or loosening during rotation due to uneven stress, thereby improving the structural stability of the entire limiting buckle 2.
[0040] As a preferred embodiment of the utility model, it can also have the following additional technical features: the rotating shaft 13 and the rotating structure 12 are arranged perpendicularly. The rotating shaft 13 and the rotating structure 12 maintain a perpendicular relationship, which helps to ensure the stability and accuracy of the rotating motion.
[0041] The structure of the rivet-free automatic limiting nut of the embodiment is reasonable, convenient to use, and can also be used for other devices with similar use requirements. In the embodiment, the rivet-free automatic limiting nut does not need additional riveting or welding steps, simplifying the installation process; it can provide good fastening effect, ensure the stability and reliability of the connection, improve the application flexibility and effectively save the cost.

Compared with the traditional rivet fastener, the fastener of the embodiment does not need to use a rivet for fixing, reduces the manufacturing cost, and simplifies the installation process. The limiting mechanism in the rivet-free automatic limiting nut can automatically prevent the fastener from loosening or falling off, thereby improving the reliability and safety of the fastener.
[0043] The working principle of the fastener of the embodiment is as follows: the rivet-free automatic limiting nut is directly placed in the opened hole, the nut body 11 is ensured to be flush with the material surface and in the correct position, an appropriate screw 3 is selected, the screw 3 is inserted through the materials to be connected, then the screw 3 is in contact with one of the inclined surfaces, the nut body 11 is rotated, and the screw 3 is corresponded with the nut body 11.
