The following describes the implementation method of the present utility model based on its overall structure.

[0038] Reference Figure 1 As shown, the embodiment of the present application provides a rivet nut connection structure, including:

[0039] Bolt part 1;

[0040] A nut portion 2 connected to the outer wall of the bolt portion 1, wherein the nut portion 2 has a first end portion 21 and a second end portion 22;

[0041] The first end portion 21 is provided with a flange portion 23, and a first plate 3 is installed on the side wall of the flange portion 23 facing the second end portion 22; the first plate 3 is sleeved on the outer wall of the nut portion 2;

[0042] The second end portion 22 is butted against a second plate 4, a washer 5 is installed between the first plate 3 and the second plate 4, the washer 5 is sleeved on the outer wall of the nut portion 2, and the washer 5 is butted against the first plate 3 and the second plate 4;

[0043] The washer 5 is made of plastic material, and the second plate 4 is sleeved on the outer wall of the bolt portion 1 , and the side of the second plate 4 facing the head 11 of the bolt portion is in contact with the head 11 .

[0044] according to Figure 1 , those skilled in the art can arrange the bolt portion 1 and the nut portion 2 to cooperate with each other. Further, the nut portion 2 has a first end portion 21 and a second end portion 22 .

[0045] A flange portion 23 is provided on the first end portion 21, and a first plate 3 is abuttedly connected on the side wall of the flange portion 23 facing the second end portion 22. The first plate 3 is sleeved on the outer wall of the nut portion 2. Further, a second plate 4 is provided on the second end portion 22. The second plate 4 is abuttedly connected to the side wall of the second end portion 22 away from the first end portion 21. A washer 5 is installed between the first plate 3 and the second plate 4. The washer 5 is sleeved on the outer wall of the nut portion 2. Moreover, the washer 5 is in abutment with the first plate 3 and the second plate 4.

[0046] In the present application, the gasket 5 is made of a plastic material, such as plastic, rubber, aluminum, copper, etc. That is, the gasket 5 may deform and age as the usage time increases.

[0047] In the above structure, the second plate 4 is in contact with the second end 22, and the first plate 3 is sleeved on the outer wall of the nut portion 2, thereby effectively maintaining the structure of the first plate 3, the second plate 4 and the washer 5. Furthermore, the stability of the connection structure is maintained when the washer 5 is deformed or aged.

[0048] Specifically, the structures of the first plate 3, the second plate 4 and the washer 5 are kept relatively stable, so that the gap size between the first plate 3 and the second plate 4 can be kept unchanged. Thus, the torque of the overall structure after the bolt part 1 and the nut part 2 are connected can be effectively kept from being attenuated.

[0049] In the above structure, the gasket 5 is made of a plastic material, and preferably, the first plate 3 and the second plate 4 are made of steel plates. That is, the first plate 3 and the second plate 4 are made of a material with a relatively high hardness. Thus, when the gasket 5 is deformed and aged, the first plate 3 and the second plate 4 can maintain a gap with the gasket 5 more stably.

[0050] The above arrangement can further improve the stability of the connection between the first plate 3 , the second plate 4 and the washer 5 in the structure matched with the bolt part 1 and the nut part 2 .

[0051] In one embodiment, in order to keep the bolt part 1 and the nut part 2 connected to external parts, the skilled person further configures the bolt part 1. Preferably, the bolt part 1 passes through the nut part 2 and maintains a threaded connection. Thus, the strength of the connection structure between the bolt part 1 and the nut part 2 can be effectively maintained while being connected to other parts.

[0052] It is understandable that in the above-mentioned connection structure, preferably, the outer diameter of the flange portion 23 is larger than the inner diameter of the first plate 3. Preferably, the outer diameter of the head portion 11 is larger than the inner diameter of the second plate 4. Specifically, those skilled in the art set the flange portion 23 to be in contact with the first plate 3, and the second plate 4 to be in contact with the head 11 of the bolt portion 1. Then, a structure in which the first plate 3, the second plate 4 and the gasket are in contact with each other can be formed. In this embodiment, the outer diameter of the flange portion 23 is set to be larger than the inner diameter of the first plate 3. Preferably, the outer diameter of the head portion 11 is larger than the inner diameter of the second plate 4. In the structure in which the first plate 3 is sleeved on the nut portion 2 and the second plate 4 is sleeved on the outer wall of the bolt portion 1, the first plate 3 and the second plate 4 can maintain a stable relative position.

[0053] In one embodiment, preferably, the flange portion 23 is provided with a plurality of first protrusions 231 on the end side facing the first plate 3, and the plurality of first protrusions 231 are embedded in the first plate 3. This can make the structure in which the first plate 3 and the flange portion 23 collide with each other more stable.

[0054] Specifically, a plurality of first protrusions 231 are embedded in the first plate 3, so as to form a structure in which the first protrusions 231 and the first plate 3 materials block each other. When the first plate 3 has a tendency to rotate, the mutually blocking structure can prevent the first plate 3 from rotating, thereby maintaining the stability of the installation position of the first plate 3.

[0055] During the installation of the first plate 3, preferably, the connection between the outer wall of the nut portion 2 and the flange portion 23 is recessed toward the position of the bolt portion 1 to form a groove 24, the groove 24 is extended and closed along the circumference of the nut portion 2, and the inner wall of the groove 24 is set against the first plate 3. Preferably, the connection between the outer wall of the nut portion 2 and the flange portion 23 extends away from the position of the bolt portion 1 to form a step portion 25, the step portion 25 is extended and closed along the circumference of the nut portion, and the outer wall of the step portion 25 is set against the first plate 3.

[0056] With the above structure, those skilled in the art can arrange that the connection between the outer wall of the nut part 2 and the flange part 23 is recessed toward the position of the bolt part 1 to form a groove 24, or that the connection between the outer wall of the nut part 2 and the flange part 23 is extended away from the position of the bolt part 1 to form a step part 25. That is, by providing the groove 24 or the step part 25, the installation of the first plate 3 can be accurately positioned.

[0057] It is understandable that, under different installation requirements, those skilled in the art may choose to set the groove 24 or the step portion 25, and then reasonably install the first plate 3. That is, the setting of the groove 24 or the step portion 25 enables the first plate 3 to meet the installation requirements in various situations. The matching structure of the nut portion 2 and the bolt portion 1 in the present application can be applied to more connection scenarios.

[0058] In the above arrangement, the connection between the outer wall of the nut portion 2 and the flange portion 23 extends away from the bolt portion 1 to form a step portion 25. Preferably, the step portion 25 is disposed toward the wall surface of the washer 5 and abuts against the washer 5. Thus, the relative position of the washer 5 can be effectively restricted.

[0059] In the installation of the washer 5, preferably, a plurality of second protrusions 26 are provided on the outer wall of the nut portion, and the plurality of second protrusions 26 are arranged at intervals along the circumference of the nut portion 2, and the plurality of second protrusions 26 are embedded in the inner wall of the washer 5. The plurality of second protrusions 26 are provided, and there is a spacing between any second protrusion 26 and an adjacent second protrusion 26. When the washer 5 is sleeved on the outer wall of the nut portion 2, the washer 5 can be engaged with the spacing between any second protrusion 26 and an adjacent second protrusion 26 under the influence of external force. In addition, the structure of the washer 5 after installation can be made more stable, and relative rotation of the washer 5 can be avoided. The reliability of the riveted nut connection structure is improved.

The embodiments of data acquisition, processing, output, judgment methods, etc. after these modifications or deformations can still fall within the scope of the optional implementation plans of this application.

[0061] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and changes to the present application without departing from the spirit of the present application. It is intended that the attached embodiments include these modifications and changes without departing from the present application.
