[0002] As a common connecting component, the pin has a wide range of applications. A pin is a standardized fastener that can provide both static fixation and relative movement with the connected parts. It is mainly used at the hinge joints of two parts to form a hinge connection. Pins are usually locked with cotter pins, ensuring reliable operation and easy disassembly.

[0003] To meet more diverse needs, segmented pins have emerged on the market. These pins typically consist of multiple segments, each with different shapes, sizes, and surface finishes. Some segments may have high-precision grinding processes to ensure the fit accuracy with other parts, while others may have special grooves or protrusions designed for mounting seals, locating keys, and other components.

[0004] However, the segments of the aforementioned segmented pins are either integrally connected or connected by slots or threads, which are not reliable enough and may separate. Therefore, we propose a multifunctional segmented pin. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-3 The image shows a multi-functional segmented pin.

[0030] Example 1

[0031] The device includes a first segmented pin 1 and a second segmented pin 4, with a connection structure between them. The connection structure includes: a connecting base 2, fixedly connected to the end of the first segmented pin 1; a locking assembly 6, disposed between the connecting base 2 and the second segmented pin 4, used to connect the connecting base 2 and the second segmented pin 4, and equipped with a driving assembly 7; and a docking assembly 5, disposed between the first segmented pin 1 and the locking assembly 6. By using the docking assembly 5 to quickly dock the connecting base 2 and the second segmented pin 4, the device achieves connection between the first segmented pin 1 and the second segmented pin 4. The segmented pin 4 is connected, and then the driving component 7 drives the locking component 6 to move, thereby connecting the connecting base 2 and the second segmented pin 4 using the locking component 6. This achieves the connection between the first segmented pin 1 and the second segmented pin 4. Afterwards, the driving component 7 is reset. At this time, the driving component 7 has a good anti-accidental collision function, so that the locking component 6 will not move abnormally, causing the first segmented pin 1 and the second segmented pin 4 to separate abnormally, thus improving the connection reliability. In addition, the design of the docking component 5 makes the segmented pin also have a quick docking function, and it is also convenient to replace the first segmented pin 1 or the second segmented pin 4 later, with good disassembly performance.

[0032] Furthermore, a stepped circular block 3 is fixedly connected to the end of the second segmented pin 4. The locking assembly 6 includes: a locking threaded post 601, which is fixedly connected to the end face of the stepped circular block 3; a circular groove 602, which is opened at one end of the connecting base 2, and an annular groove 603 is opened inside the circular groove 602; a rotating ring 604, which is rotatably connected to the inside of the annular groove 603, and a connecting ring 605 is fixedly connected to the inner side of the rotating ring 604, and the connecting ring 605 is threadedly connected to the locking threaded post 601. After the second segmented pin 4 is docked with the first segmented pin 1 by the docking assembly 5, the driving assembly 7 drives the connecting ring 605 to rotate, and the connecting ring 605 drives the rotating ring 604 to rotate along the annular groove 603, so that the connecting ring 605 and the locking threaded post 601 can be screwed together.

[0033] Furthermore, the drive assembly 7 includes: an inner ring groove 701, which is formed inside the connecting ring 605, and an annular through groove 702 is formed on one side of the inner ring groove 701; a movable ring 703, which is rotatably connected inside the inner ring groove 701; a connecting rod 704, which is fixedly connected to one side of the movable ring 703, and the end of the connecting rod 704 that passes through the annular through groove 702 is fixedly connected to the drive ring 705, and a return spring 706 is sleeved on the outer surface of the connecting rod 704; and a limiting assembly, which is disposed between the movable ring 703 and the connecting ring 605, and includes a plug 707 fixedly connected to the outer surface of the movable ring 703 and a slot 708 formed on the other side of the inner ring groove 701, and the number of slots 708 and the number of plugs 707 are at least two. By pushing the drive ring 705 inward, the drive ring 705 drives the connecting rod 704 and its movable ring 703 to move inward until the insert block 707 is inserted into the slot 708. At the same time, the return spring 706 is compressed. Then, the drive ring 705 is rotated, causing the drive ring 705 to rotate and the movable ring 703 to rotate. The mutual limiting of the insert block 707 and the slot 708 causes the connecting ring 605 to rotate, which facilitates the connection between the connecting ring 605 and the locking threaded post 601. After the drive ring 705 is released, the return spring 706 drives the drive ring 705 to return to its original position, causing the insert block 707 to separate from the slot 708. At this time, even if the drive ring 705 is rotated, the connecting ring 605 will not rotate abnormally, which has good anti-accidental collision performance. In addition, the stepped circular block 3 can also block the drive ring 705.

[0034] Furthermore, the docking assembly 5 includes a docking groove 501 formed on one side of the circular groove 602 and a docking block 502 fixedly connected to one end of the locking threaded post 601. The outer contour dimensions of the docking block 502 are adapted to the inner contour dimensions of the docking groove 501, and the outer contour of the docking block 502 is set as a square. By inserting the docking block 502 into the docking groove 501, the docking block 502 and the docking groove 501 are mutually limited, thereby preventing relative movement after the first segmented pin 1 and the second segmented pin 4 are connected.

[0035] Example 2

[0036] Example 2 further improves upon Example 1 by having the depth of the mating groove 501 greater than the thickness of the connecting ring 605, and the diagonal length of the mating block 502 less than the inner diameter of the driving ring 705; this ensures that the mating block 502 and the mating groove 501 are already inserted and positioned before the connecting ring 605 is connected to the locking threaded post 601.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
