[0037] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0038] In the description of the present utility model, it should be noted that the terms "upper", "middle", "lower", "inner", "outer", "front", "back" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. The terms "first", "second", and "third" are used for descriptive purposes only, 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 utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0039] Reference Figure 1 As shown, an embodiment of the present application provides a connecting piece, including:

[0040] The main body 1 has an axis, and the main body 1 is provided with a first end 11 and a second end 12;

[0041] The first end portion 11 is provided with a plate portion 2, the second end portion 12 is provided with a riveting portion 3, and the middle position of the main body portion 1 is provided with an anti-rotation portion 4;

[0042] The anti-rotation part 4 is composed of a plurality of protrusions 41 arranged at intervals, and the plurality of protrusions 41 are distributed along the circumference of the main body 1, and the space between any protrusion 1 and the adjacent protrusion 1 is used to accommodate the material of the plate;

[0043] A first receiving groove 5 is formed between the plate portion 2 and the anti-rotation portion 4 and a second receiving groove 6 is formed between the riveting portion 3 and the anti-rotation portion 4. The first receiving groove 5 and the second receiving groove 6 are used to accommodate the material of the plate.

[0044] according to Figure 1 Those skilled in the art may set the main body 1 to have an axis. Also, the main body 1 may be provided with a first end 11 and a second end 12 .

[0045] Furthermore, the plate portion 2 may be provided at the first end portion 11 of the main body portion 1 , and the riveting portion 3 may be provided at the second end portion 12 . An anti-rotation portion 4 is provided at the middle position of the main body portion 1 .

[0046] By means of the above structure, a person skilled in the art can apply external force to the plate portion 2 during the process of connecting the connector and the plate. Under the action of the external force, the riveting portion 3 is pressed into the plate. The external force is continuously applied to the plate portion 2, and the anti-rotation portion 4 can be further pressed into the plate. The riveting process continues until the plate portion 2 is pressed into the plate.

[0047] Furthermore, in the above structure, those skilled in the art arrange the anti-rotation portion 4 to be composed of a plurality of protrusions 41 arranged at intervals, the plurality of protrusions 41 are distributed circumferentially along the main body 1, and any protrusion 1 and an adjacent protrusion 1 are used to accommodate the material of the plate.

[0048] In the above structure, the anti-rotation part 4 is composed of a plurality of protrusions 41. That is, the plurality of protrusions 41 are spaced and distributed along the circumference of the main body 1. Thus, a gap can be formed between any protrusion 41 and an adjacent protrusion 41. After the anti-rotation part 4 is riveted into the plate, the material of the inner wall of the plate will enter into a gap between any protrusion 41 and an adjacent protrusion 41 during the extrusion process. Thus, a structure in which the anti-rotation part 4 and the plate material are in conflict can be formed.

[0049] It is understandable that when the connecting member and the plate rotate relative to each other, the material of the plate contacts the inner wall of the anti-rotation portion 4, thereby forming a force to resist the rotation between the connecting member and the plate, thereby effectively preventing the connecting member and the plate from rotating relative to each other.

[0050] In the above structure, those skilled in the art may also arrange for the plate portion 2 and the anti-rotation portion 4 to be recessed toward the axis to form a first receiving groove 5, and for the riveting portion 3 and the anti-rotation portion 4 to be recessed toward the axis to form a second receiving groove 6.

[0051] By means of the above structure, during the process of squeezing the connecting member into the plate, the material of the plate can enter the first containing groove 5 and the second containing groove 6 under the squeezing action of external force.

[0052] When the connecting member and the plate are relatively disengaged, the material of the plate is squeezed and collides with the first receiving groove 5 and the second receiving groove 6, thereby forming a force to resist the connection member from being disengaged.

[0053] In summary, the arrangement of the anti-rotation portion 4 and the first receiving groove 5 and the second receiving groove 6 can prevent the connector from relative rotation and disengagement in the structure connected to the plate, thereby significantly improving the connection stability of the connector.

[0054] In one embodiment, preferably, the outer diameter of the plate portion 2 is larger than the outer diameter of the riveting portion 3. In the above structure, the plate portion 2 is used to bear external force. The outer diameter of the plate portion 2 is larger than the outer diameter of the riveting portion 3, so that after the connecting piece is riveted to the plate, the riveted joint can be sealed by the plate portion 2. That is, the plate portion 2 can cover the gap at the riveted joint. In this way, after the connecting piece is riveted, foreign matter is prevented from entering the riveted joint, thereby preventing the connecting piece from shaking relative to the connecting piece when connected.

[0055] In this embodiment, the anti-rotation part 4 can be set by a person skilled in the art. Preferably, the outer diameter of the plate part 2 is larger than the outer diameter of the anti-rotation part 4. Thus, the connector can be further stabilized in the riveted structure. At the same time, the plate part 2 has a large contact area, which can avoid the situation where the local pressure is too high during the process of applying external force to the plate part 2. Thus, the plate part 2 can be effectively prevented from being significantly deformed or damaged during the process of applying external force. Thus, the stability of the plate part 2 during riveting can be improved.

[0056] In the setting of the plate portion 2, in another embodiment, preferably, the cross section of the plate portion 2 is circular or polygonal. The cross-sectional area of ​​the plate portion 2 can be set according to the actual operation conditions, thereby meeting the conditions for riveting different plates.

[0057] In the above structure, the second receiving groove 6 is connected to the riveting part 3. Preferably, the second receiving groove 6 is connected to the riveting part 3 through an inclined surface. Thus, stress concentration at the connection between the second receiving groove 6 and the riveting part 3 can be avoided during the process of the connecting member being pressed into the plate. Thus, the stability of the second receiving groove 6 and the riveting part 3 during the connection process can be significantly improved.

[0058] In the above structure, those skilled in the art can accommodate the material of the plate by providing the first containing groove 5 and the second containing groove 6. Preferably, the side wall of the second end 12 is recessed toward the position of the first end 11 to form a circular groove 7. Those skilled in the art can also accommodate the material of the plate through the aforementioned circular groove 7, thereby avoiding local serious damage to the plate during the process of connecting the connecting member and the plate. Thus, the stability of the plate structure can be maintained.

[0059] This specification also provides a plate connection structure, including:

[0060] The main body 1 has a first end 11 and a second end 12;

[0061] The first end portion 11 is provided with a plate portion 2, and the plate portion 2 abuts against the inner wall of the first plate 8;

[0062] The second end portion 12 is provided with a riveting portion 3, which contacts the inner wall of the second plate 9;

[0063] An anti-rotation portion 4 is provided in the middle of the main body 1. The anti-rotation portion 4 is formed by a plurality of protrusions spaced apart along the circumference of the main body 41. The anti-rotation portion 4 is disposed in contact with the inner walls of the first plate 8 and the second plate 9 at the same time.

[0064] Among them, the first receiving groove 5 is formed by being recessed toward the direction of the axis between the plate portion 2 and the anti-rotation portion 4, and the second receiving groove 6 is formed by being recessed toward the direction of the axis between the riveting portion 3 and the anti-rotation portion 4. The first receiving groove 5 is used to accommodate the material of the first plate 8, and the second receiving groove 6 is used to accommodate the material of the second plate 9.

[0065] according to Figure 1 , a person skilled in the art sets a first plate 8 and a second plate 9 for riveting. Specifically, a main body 1 is provided, and the main body 1 has a first end 11 and a second end 12. A plate 2 is provided at the first end 11, and a riveting portion 3 is provided at the second end 12. The plate 2 mentioned above abuts against the inner wall of the first plate 8, and the riveting portion 3 abuts against the inner wall of the second plate 9. An anti-rotation portion 4 is provided at the middle position of the main body 1, and the anti-rotation portion 4 abuts against the inner walls of the first plate 8 and the second plate 9 at the same time.

[0066] That is, in the above structure, a person skilled in the art can apply external force to the plate portion 2, so that the riveting portion 3 is pressed into the first plate 8. Then, the external force is continued to be applied to the plate portion 2, so that the riveting portion 3 is continued to be pressed into the second plate 9. When the riveting portion 3 is pressed into the second plate 9, the plate portion 2 is pressed into the first plate 8, and the riveting process can be completed.

[0067] In the above-mentioned riveting process, preferably, any protrusion 41 and the adjacent protrusion 41 are used to accommodate the material of the first plate 8 and the second plate 9. The anti-rotation portion 4 is composed of a plurality of protrusions 41. That is, the plurality of protrusions 41 are spaced and distributed along the circumference of the main body 1. Thus, a gap can be formed between any protrusion 41 and the adjacent protrusion 41. After the anti-rotation portion 4 is riveted into the plate, the material of the inner wall of the plate will enter the gap between any protrusion 41 and the adjacent protrusion 41 during the extrusion process. Thus, a structure in which the anti-rotation portion 4 and the materials of the first plate 8 and the second plate 9 conflict with each other can be formed.

[0068] It can be understood that when the connecting member and the first plate 8 and the second plate 9 rotate relative to each other, the materials of the first plate 8 and the second plate 9 collide with the inner wall of the anti-rotation portion 4, thereby forming a force that resists the rotation between the connecting member and the first plate 8 and the second plate 9. Thus, relative rotation can be effectively prevented from occurring in the structure in which the connecting member and the first plate 8 and the second plate 9 are connected.

[0069] In one embodiment, those skilled in the art may also arrange for the plate portion 2 and the anti-rotation portion 4 to be recessed toward the axis to form a first receiving groove 5, and for the riveted portion 3 and the anti-rotation portion 4 to be recessed toward the axis to form a second receiving groove 6.

[0070] By means of the above structure, during the process of the connecting member being squeezed into the first plate 8 and the second plate 9, the materials of the first plate 8 and the second plate 9 can be squeezed into the first receiving groove 5 and the second receiving groove 6 by the external force. Specifically, the material of the first plate 8 is squeezed into the first receiving groove 5, and the material of the second plate 9 is squeezed into the second receiving groove 6.

[0071] When the connector and the plate come out of relative motion, the materials of the first plate 8 and the second plate 9 are squeezed and rubbed against the first receiving groove 5 and the second receiving groove 6, thereby forming a force to resist the connector from coming out.

[0072] Preferably, the distance between the riveting portion 3 and the first end 11 is smaller than the distance between the wall of the second plate 9 away from the first plate 8 and the first end 11. That is, after the riveting portion 3 is pressed into the second plate 9, the riveting portion 3 will not form a protrusion on the end surface of the second plate 9 away from the first plate 8, thereby not affecting the installation of the second plate 9.

[0073] For the first plate 8, preferably, the distance between the plate portion 2 and the second end 12 is smaller than the distance between the wall of the first plate 8 away from the second plate 9 and the second end 12. After the plate portion 2 is pressed into the first plate 8, the plate portion 2 will not form a protruding portion on the wall of the first plate 8 away from the second plate 9, thereby not affecting the continued installation of the first plate 8.

[0074] Although different specific embodiments are mentioned in the content of this application, this application is not limited to the situations described in the industry standards or embodiments, etc. Some industry standards or slightly modified implementation plans based on the implementation of the custom methods or embodiments can also achieve the same, equivalent or similar, or predictable implementation effects after deformation of the above embodiments. 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.

[0075] 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.
