The following describes the implementation of the present invention based on its overall structure.

[0043] Reference Figure 1 As shown, an embodiment of the present application provides a multifunctional fastener, comprising:

[0044] The shaft portion 1 has a first connecting end 11 and a second connecting end 12;

[0045] The driving part 2 is sleeved on the first connecting end 11, the first connecting end 11 is also connected to the first locking member 3, and the outer wall of the driving part 2 is sleeved with the first connecting member 4;

[0046] A second locking member 5 connected to the second connecting end 12, wherein the outer wall of the second locking member 5 is provided with a second connecting member 6;

[0047] A conductive bushing 7 is sleeved on the outer wall of the shaft portion 1, and two ends of the conductive bushing 7 are respectively in contact with the first connecting member 4 and the second connecting member 6;

[0048] Among them, a guide portion 51 is provided on the outer side of the outer wall of the second locking member 5 away from the second connecting end 12, and the side of the guide portion 51 close to the second connecting end 12 is recessed to form a receiving groove 52 for accommodating the material of the second connecting member 6. A stop portion 53 is provided on the end side of the second locking member 5 away from the guide portion 51, and a first knurled portion 54 is provided between the stop portion 53 and the receiving groove 52 for connecting the second connecting member 6.

[0049] according to Figure 1 , those skilled in the art can set the shaft portion 1 to connect the first connecting member 4 and the second connecting member 6. Specifically, the driving portion 2, the conductive bushing 7, the first locking member 3 and the second locking member 5 can be sleeved on the outer wall of the shaft portion 1 to complete the connection between the first connecting member 4 and the second connecting member 6.

[0050] Furthermore, in the above arrangement, the shaft portion 1 is provided with a first connecting end 11 and a second connecting end 12. The driving portion 2 is mounted near the first connecting end 11. In an alternative embodiment, the driving portion 2 can be directly connected to the first connecting end 11, which is further connected to the first locking member 3. The connection structure between the first locking member 3 and the first connecting end 11 can restrict the relative position of the driving portion 2. Preferably, the driving portion 2 is configured as a hexagonal nut.

[0051] Furthermore, a first connecting member 4 is sleeved on the outer wall of the driving portion 2. That is, the first connecting member 4 and the shaft portion 1 are connected to the first connecting end 11 through the driving portion 2. The first locking member 3 can limit the first connecting member 4 during the process of limiting the position of the driving portion 2.

[0052] The second connecting end 12 of the shaft portion 1 is connected to the second locking member 5, and the outer wall of the second locking member 5 is provided with a second connecting member 6. In combination with the above embodiment, the first connecting member 4 and the second connecting member 6 can be connected through the first connecting end 11 and the second connecting end 12 of the shaft portion 1.

[0053] Those skilled in the art may further sleeve a conductive bushing 7 on the outer wall of the shaft portion 1 to complete the structure in which the first connector 4, the second connector 6, and the conductive bushing 7 are connected to each other. Specifically, the conductive bushing 7 is disposed between the first connector 4 and the second connector 6, and both sides of the conductive bushing 7 respectively contact the first connector 4 and the second connector 6.

[0054] In the above embodiment, those skilled in the art complete the positioning and connection of the second connecting member 6 by providing the second locking member 5 .

[0055] Specifically, a guide portion 51 is provided on the outer side of the outer wall of the second locking member 5 away from the second connecting end 12. The provision of the guide portion 51 allows the second locking member 5 to stably complete the sleeve installation of the second connecting member 6 during the process of connecting with the second connecting member 6.

[0056] Furthermore, the side of the guide portion 51 near the second connecting end 12 is recessed to form a receiving groove 52 for accommodating the material of the second connecting member 6. In other words, the material inside the second connecting member 6 can be accommodated during the compression fit between the second connecting member 6 and the inner wall of the second locking member 5. During the mutual engagement between the receiving groove 52 and the second connecting member 6, the inner wall of the groove 52 and the second connecting member 6 can be described as a structure that supports each other, thereby effectively preventing the second connecting member 6 from falling out.

[0057] A stopper 53 is provided on the end of the second locking member 5 away from the guide portion 51. A first knurled portion 54 is provided between the stopper 53 and the receiving groove 52 for connecting to the second connecting member 6. During the connection process of the second connecting member 6, the first knurled portion 54 can squeeze and discharge the material of the second connecting member 6, thereby forming a structure that interlocks with the first knurled portion 54.

[0058] The above structure can prevent the second connecting member 6 from rotating relative to the second locking member 5 after they are connected. That is, the first knurled portion 54 can form an interlocking structure with the material inside the second connecting member 6. When the second connecting member 6 has a tendency to rotate, the material of the second connecting member 6 and the side walls of adjacent teeth in the first knurled portion 54 will interfere with each other, thereby generating a force to prevent rotation.

[0059] It is understood that when the first knurled portion 54 squeezes the material of the second connector 6, the material of the second connector 6 can be squeezed into the groove, thereby preventing damage to the connected structure. Preferably, the outer diameter of the stopper portion is larger than the outer diameter of the first knurled portion. The provision of the stopper portion 53 effectively prevents the material of the second connector 6 from overflowing outside the second connector 6, preventing debris from affecting other components.

[0060] In summary, those skilled in the art can set the first locking member 3 and the second locking member 5 to limit the installation positions of the first connecting member 4 and the second connecting member 6, so that the first connecting member 4 and the second connecting member 6 can work stably after being connected.

[0061] In the above arrangement, preferably, the second connection end 12 is connected to the second locking member 5 via a thread. In this embodiment, the second connection end 12 is fixedly connected to the second locking member 5 via an external thread. The external thread connection can enhance the connection effect of the second connection member.

[0062] In the above embodiment, according to Figure 1 , those skilled in the art can set the outer diameter of the driving portion 2 to be larger than the outer diameter of the shaft portion 1. Preferably, the outer diameter of the driving portion 2 is smaller than the maximum outer diameter of the shaft portion 1. That is, in this embodiment, the outer diameter of the driving portion 2 can be set to be smaller than the maximum outer diameter of the shaft portion 1. According to the above embodiment, the driving portion 2 is made of a hexagonal nut. In this embodiment, the outer diameter of the hexagonal nut can be set to be smaller than the maximum outer diameter of the shaft portion 1.

[0063] By means of the above-mentioned mechanism, the outer diameter of the hexagonal nut is smaller than the maximum outer diameter of the shaft 1, thereby avoiding the formation of a protruding part of the driving part 2 on the outer wall of the shaft 1, thereby optimizing the assembly order of the shaft 1 and making the installation order of the first connecting member 4 and the second connecting member 6 more flexible.

[0064] In the above structure, preferably, the first connection end 11 is connected to the first locking member 3 via a thread. More preferably, the first connection end 11 is connected to the first locking member 3 not only via an external thread but also via an internal thread.

[0065] It can be understood that connecting through internal threads can reduce the overall weight of the connecting structure of the shaft portion 1, thereby reducing the transportation cost of the connecting structure of the shaft portion 1.

[0066] In the above structure, the first connecting member 4 is adjacent to the first locking member 3 . Preferably, a gasket 8 is installed between the first locking member 3 and the first connecting member 4 , and the gasket 8 contacts both the first locking member 3 and the first connecting member 4 .

[0067] The provision of the gasket 8 can prevent the first locking member 3 and the first connecting member 4 from being damaged by collision, while making the installation of components on the outer wall of the shaft portion 1 more compact and stable.

[0068] In one embodiment, preferably, the outer wall of the shaft portion 1 is provided with a second knurled portion 13 for forming an interference fit between the shaft portion 1 and the conductive bushing 7. Specifically, the second knurled portion 13 can be provided near the first connecting end 11 of the shaft portion 1 and can interfere with the inner wall of the conductive bushing 7.

[0069] By means of the above structure, an interference fit connection relationship is formed between the shaft portion 1 and the conductive bushing 7, thereby being more stable during transportation.

[0070] according to Figure 1 Preferably, the first connecting member 4 is vertical to the second connecting member 6. Thus, the first connecting member 4 and the second connecting member 6 can be connected in multiple directions.

[0071] In the above embodiment, preferably, the first connecting end 11 does not protrude from the side wall of the first connecting member 4, and the second connecting end 12 does not protrude from the side wall of the second connecting member 6. That is, after the first connecting member 4 and the second connecting member 5 are connected, no protrusions are formed on the side wall opposite the shaft portion 1. This allows the structure connecting the first connecting member 4 and the second connecting member 5 to be well concealed. Since there are no protrusions above or below, the application scenarios are more flexible, especially in confined spaces and locations where the installation sequence is restricted.

[0072] Preferably, both the first connector 4 and the second connector 6 are configured as conductive busbars. Specifically, when configuring the conductive busbar connection mechanism, connection can be achieved using the aforementioned shaft 1, drive unit 2, and first and second locking members 3 and 5. This provides a more stable connection between the two conductive busbars and facilitates installation. The provision of the second locking member 5 prevents the connected conductive busbars from loosening and potentially causing failure.

[0073] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. 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.

[0074] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and variations to the present application without departing from the spirit of the present application. It is intended that the appended embodiments include these modifications and variations without departing from the present application.
