[0028] Reference Figures 1 to 3 This application provides a multifunctional roller assembly, including:

[0029] Rotary sleeve 1, wherein a first through hole 11 is formed inside the rotating sleeve 1 along its axial direction, and the top of the rotating sleeve 1 has a stepped portion 12 extending radially outward;

[0030] A positioning pin 2 is inserted into the first through hole 11. The positioning pin 2 has a second through hole 21 for inserting a wire harness inside along its axial direction. The positioning pin 2 includes a base 23 and a connecting part 22 disposed on the upper end of the base 23. The connecting part 22 is inserted into the first through hole 11 and rotates relative to the rotating sleeve 1.

[0031] The outer wall of the connecting part 22 is provided with an annular groove 24 that runs radially inward. After the sliding sleeve and the positioning pin 2 are riveted, a protrusion 13 that extends radially inward is formed on the inner wall of the first through hole 11. The protrusion 13 flows radially to be inserted into the annular groove 24, so that the rotating sleeve 1 and the positioning pin 2 are prevented from separating along the axial direction.

[0032] Using the above structure, refer to Figure 3 Before riveting, the rotating sleeve 1 is fitted onto the outside of the positioning pin 2. A gap exists between the first through hole 11 of the rotating sleeve 1 and the positioning pin 2, allowing the rotating sleeve 1 to slide relative to the positioning pin 2. After the positions of the rotating sleeve 1 and the positioning pin 2 are determined, a force is applied from the end face of the rotating sleeve 1, resulting in a stepped portion 12 and an inwardly extending protrusion 13 formed on the inner wall of the rotating sleeve 1 in the radial direction. (Refer to...) Figure 1 The protrusion 13 can flow radially after the rotating sleeve 1 and the positioning pin 2 are riveted together, so as to engage with the annular groove 24 of the positioning pin 2, thereby allowing the rotating sleeve 1 to rotate relative to the positioning pin 2 and completing the installation of the roller assembly. The multifunctional roller assembly in this embodiment has a simple structure, requiring only two sub-components to realize the function of the roller, and is easy to assemble. The rotating sleeve 1 has a uniform wall thickness, is not easily deformed during use, and reduces the cost of use. The step 12 can realize the positioning function and has an I-beam hook function for hanging and sliding the plate 3. The rotating sleeve 1 and the positioning pin 2 can maintain relative rotation after connection, so that the roller assembly can be used in various connection situations, improving the ease of use of the connector. The second through hole 21 can realize the function of fixing the wire harness.

[0033] Specifically, in this embodiment, the radial width of the protrusion 13 is less than the radial width of the annular groove 24, and the axial height of the protrusion 13 is less than the axial height of the annular groove 24, so that there is a certain gap between the protrusion 13 and the annular groove 24, allowing the rotating sleeve 1 to rotate relative to the positioning pin 2.

[0034] Specifically, in this embodiment, the end face of the rotating sleeve 1 is flush with the end face of the connecting part 22, and the bottom of the rotating sleeve 1 is in contact with the end face of the base 23.

[0035] Specifically, in this embodiment, a first gap is provided between the connecting part 22 and the inner wall of the first through hole 11. The first gap is smaller than the radial width of the protrusion 13. The first gap is smaller than the radial width of the protrusion 13 so that the protrusion 13 can be embedded in the annular groove 24, preventing the positioning pin 2 from falling out of the rotating sleeve 1 and ensuring that the roller assembly can rotate smoothly.

[0036] Specifically, in this embodiment, the outer diameter of the base 23 is larger than the outer diameter of the rotating sleeve 1, and the outer diameter of the base 23 is larger than the outer diameter of the connecting part 22. The base 23 abuts against the rotating sleeve 1 from the bottom to prevent the rotating sleeve 1 from falling off the positioning pin 2.

[0037] Specifically, in this embodiment, the rotating sleeve 1 and the positioning pin 2 form an "I" shaped structure.

[0038] Reference Figure 2 This specification also provides a connection structure, employing the multi-functional roller assembly as described above, including:

[0039] Plate 3, wherein the plate 3 is provided with preset mounting holes;

[0040] The rotating sleeve 1 passes through the mounting hole, and part of the outer wall of the base 23 is connected to the plate 3, so that the plate 3 and the rotating sleeve 1 rotate relative to each other.

[0041] Specifically, in this embodiment, the base 23 includes a bearing surface that can abut against the plate 3 and a riveting part 25 disposed on the bearing surface. A portion of the outer wall of the riveting part 25 is provided with knurled teeth, and the inner wall material of the mounting hole is riveted to the outer wall of the riveting part 25.

[0042] With the above structure, the mounting hole of the plate 3 is passed through the rotating sleeve 1, so that the plate 3 abuts against the bearing surface of the base 23. The plate 3 is connected to the riveting part 25. There are gaps in the knurled tooth structure, which can form an anti-torque structure. The material of the plate 3 can be squeezed into the gaps, so that the positioning pin 2 can drive the plate 3 to rotate relative to the rotating sleeve 1. A force is applied to the end face of the rotating sleeve 1 to form a step part 12 and a protrusion 13 extending inward in the radial direction on the inner wall of the rotating sleeve 1. The protrusion 13 can flow radially after the rotating sleeve 1 and the positioning pin 2 are riveted to fit into the annular groove 24 of the positioning pin 2, so that the rotating sleeve 1 can rotate relative to the positioning pin 2, thus completing the installation of the roller assembly. The step portion 12 can achieve the positioning function and has the function of hooking the I-beam nail for hanging and sliding the plate 3. The rotating sleeve 1 and the positioning pin 2 can maintain relative rotation after connection, so that the roller assembly can be used in a variety of connection situations, improving the ease of use of the connector. The second through hole 21 can achieve the function of fixing the wire harness.

[0043] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Slightly modified implementations based on certain industry standards or custom methods or embodiments can also achieve the same, equivalent, or similar, or predictable, implementation effects as the above embodiments. Embodiments applying these modified or modified data acquisition, processing, output, and judgment methods still fall within the scope of optional implementations of this application.

[0044] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
