The terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0036] Reference Figure 1 As shown, an embodiment of the present application provides a riveted fastening structure, comprising:

[0037] The connecting portion 1 has a mounting end 11 for connecting the plate 2;

[0038] A head portion 12 is sleeved on an outer wall of the mounting end 11 , and the head portion 12 has a first side 121 and a second side 122 away from the first side 121 ;

[0039] The outer wall of the first side 121 is recessed toward the second side 122 to form a plurality of recessed portions 123 for accommodating the material of the plate 2. The plurality of recessed portions 123 are spaced apart from each other to form spaced apart ribs 124.

[0040] The outer diameter of the mounting end 11 away from the first side 121 decreases linearly toward the outer diameter of the end close to the first side 121 , and a plurality of arcuate surfaces 111 are distributed on the outer wall of the mounting end 11 , and the plurality of arcuate surfaces 111 all contact the inner wall of the plate 2 .

[0041] according to Figure 1 , those skilled in the art can set up a structure in which the connecting part 1 and the plate 2 are connected to each other, wherein the plate 2 is riveted to the connecting part 1, so that a stable connection of the plate 2 can be achieved.

[0042] According to the above content, those skilled in the art can provide a mounting end 11 on the connecting portion 1 , and by providing the mounting end 11 , the connection between the connecting portion 1 and the plate 2 can be configured.

[0043] Furthermore, a head 12 may be provided on the mounting end 11, wherein the outer diameter of the head 12 is larger than the maximum outer diameter of the mounting end 11. During the installation process, the head 12 may be provided so as to be sleeved on the mounting end 11. The head 12 has a first side 121 and a second side 122 away from the first side 121.

[0044] With the above structure, those skilled in the art can configure the first side 121 of the head 12 to have a plurality of recessed portions 123 that are recessed toward the second side 122 .

[0045] In the above embodiment, those skilled in the art connect the sheet material 2 via the connecting portion 1, wherein one side of the sheet material 2 contacts the first side 121. During the contact or riveting process, the material on the sidewall of the sheet material 2 facing the first side 121 is squeezed into the recessed portion 123. In the embodiment, multiple recessed portions 123 are arranged at intervals to form multiple interlocking connection units with the material of the sheet material.

[0046] In the above embodiment, the plurality of recesses 123 are spaced apart, so that ribs 124 can be formed between any of the recesses 123. The sidewalls of the ribs 124 can interfere with the material of the plate 2, thereby forming a mutually resisting structure.

[0047] With the above structure, in the structure in which the connecting part 1 is connected to the plate 2, if the plate 2 has a tendency to rotate relative to the connecting part 1, the material of the plate 2 will resist the rib 124, thereby generating a force to resist the rotation, thereby effectively avoiding rotation failure of the riveted fastening structure.

[0048] In the above-mentioned interlocking structure, the material of the plate 2 cooperates with the recessed portion 123 so that no uneven protrusions appear on the wall surface of the first side 121 .

[0049] In summary, the provision of the plurality of recessed portions 123 and the plurality of ribs 124 can make the connection surface between the plate 2 and the connection portion 1 smoother, and the force preventing rotation more stable.

[0050] Furthermore, the outer diameter of the end of the mounting end 11 away from the first side 121 decreases linearly toward the end close to the first side 121 , and a plurality of arcuate surfaces 111 are distributed on the outer wall of the mounting end 11 , and the plurality of arcuate surfaces 111 all contact the inner wall of the plate 2 .

[0051] With the above structure, the outer diameter of the end of the mounting end 11 away from the first side 121 decreases linearly toward the outer diameter of the end close to the first side 121, so that an arc-shaped surface can be formed on the outer wall of the mounting end 11, and the arc-shaped surface is distributed on the entire circumference of the mounting end 11.

[0052] It is understood that the outer diameter of the arcuate surface formed above, at the end away from the first side 121, is larger than the outer diameter at the end closer to the first side 121. During the connection process of the plates 2, the inner wall of the plates 2 contacts the outer wall of the connecting portion 1. Under the action of the arcuate surface, the inner wall of the plates 2 forms a corresponding curved surface. In other words, the inner wall of the plates 2 also forms an arcuate curved surface.

[0053] With the above structure, when the plate 2 has a tendency to come out, the arc-shaped surfaces can interfere with each other to form a force to resist coming out, thereby making the structure of the connection between the connecting plate 1 and the plate 2 more stable.

[0054] In summary, by providing the curved surface of the outer wall of the mounting end 11 , the ribs 124 and the recessed portion 123 , the connection between the connecting portion 1 and the plate 2 can be prevented from rotating and falling out.

[0055] In addition, a plurality of arcuate surfaces 111 are provided on the outer wall of the mounting end 11. Figure 1 Multiple arcuate surfaces 111 are spaced apart on the outer wall of the connecting portion 1. When the plate 2 contacts the outer wall of the mounting end 11, the multiple arcuate surfaces 111 contact the inner wall of the plate 2, thereby forming a concave-convex matching structure, which can further provide a force to prevent the plate 2 from rotating relative to each other.

[0056] In the above arrangement, preferably, the connecting portion 1 further comprises a threaded portion 13, wherein the threaded portion 13 comprises an external thread and an internal thread. When the threaded portion 13 is configured as an external thread, it can be configured as a bolt. When the threaded portion 13 is configured as an internal thread, it can be configured as a nut structure or a blind hole nut structure.

[0057] In the above arrangement, the recessed portion 123 is provided to cooperate with the material of the plate 2, thereby maintaining a seal on the mounting surface of the plate 2. Preferably, the inner wall of the recessed portion 123 away from the connecting portion is arc-shaped, thereby achieving stable and complete contact with the material of the plate 2.

[0058] In another alternative embodiment, the cross-section of the recess 123 parallel to the head 12 is preferably polygonal. This polygonal cross-section allows the material of the sheet 2 embedded in the recess 123 to contact the inner wall of the recess 123 when the sheet 2 tends to rotate, thereby generating a force that resists rotation. This arrangement effectively prevents the sheet 2 from rotating and further enhances the stability of the riveted connection.

[0059] In an optional embodiment, the plurality of ribs 124 are preferably evenly spaced, so that the plurality of ribs 124 can maintain uniform and stable force. Preferably, the plurality of curved surfaces 111 are evenly spaced, so that the force exerted by the curved surfaces 111 against the inner wall of the plate 2 is more uniform.

[0060] In the above structure, one end of the rib 124 is connected to the outer wall of the mounting end 11. In order to prevent the connection of the rib 124 from interfering with the arcuate surface 111, preferably, any rib 124 is kept separate from the multiple arcuate surfaces 111, so that the rib 123 and the arcuate surface 111 can work normally.

[0061] More preferably, the distances between any rib 124 and the adjacent arc-shaped surface 111 are equal, so that the force between the rib 124 and the arc-shaped surface 111 can be kept uniform, thereby extending the service life of the connecting part 1.

[0062] In an optional embodiment, preferably, the outer wall of the mounting end 11 is provided with a tooth portion, and the tooth portion includes straight teeth and helical teeth, so that the outer wall of the mounting end 11 can provide a greater force to prevent rotation when cooperating with the plate 2, thereby making the connection between the connecting part 1 and the plate 2 more stable.

Some industry standards or slightly modified implementations based on customized methods or implementations described in the embodiments can also achieve the same, equivalent, or similar implementation effects as the above embodiments, or predictable implementation effects after modification. Examples that apply these modified or modified data acquisition, processing, output, judgment methods, etc. can still fall within the scope of optional implementation schemes of this application.
