Description

Technical Field

[0001] The utility model relates to the technical field of tripods, in particular to a high-efficiency self-lubricating tripod cylindrical part. Background Art

[0002] A tripod is a mechanical component commonly used in transmission systems in automotive and other applications. It typically consists of three spherical pins and a cylindrical body. The three spherical pins are evenly distributed around the cylindrical body, forming a tripod-like structure.

[0003] At present, the existing tripod (such as patent announcement number: CN213954187U) discloses a tripod structure. By adding an inner ring structure, the tripod shaft neck and the inner ring can not only slide relative to each other, but also rotate. In theory, the ball ring and the ball path of the tripod can remain parallel during movement. When the swing angle increases, the axial force remains stable, and the transmission efficiency of the ball cage is also improved. The tripod shaft head and the inner ring adopt a spherical surface to spherical surface fit. Compared with the fit between the ball ring and the cylindrical surface, this reduces friction and axial force and improves transmission efficiency.

[0004] However, during the implementation of the above technical solution, it was found that at least the following technical problems exist: the tripods rotate relative to each other, and for long-term use, the connection ends need to be lubricated, but the lubricant is filled through the gaps at the connection ends. However, the connection ends are relatively tight, and only a small amount of lubricant can be counted into the interior of the tripods, resulting in limited lubrication effect.

[0020] The embodiment of the present application provides a high-efficiency self-lubricating tripod cylindrical part, which effectively solves the problem of long-term use and the need to lubricate the connection end. However, the lubricant is filled through the gap at the connection end, but the connection end is relatively tight, and only a small amount of lubricant can be counted into the interior of the tripod, and the lubrication effect is limited. By pushing the docking sleeve out of the interior of the sealing sleeve, the lubricant is allowed to enter the interior of the connecting sleeve through the mounting tube. At the same time, the pipeline inside the support plate is connected with the interior of the connecting sleeve, and the lubricant enters the interior of the support plate through the connecting sleeve. Leakage ports are opened on both sides of the support plate, and the lubricant enters the interior of the fixed ring through the leakage ports. The lubricant can be transported to the interior of the fixed ring for lubrication, thereby ensuring the lubrication effect.

[0021] Example

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem that the connection end needs to be lubricated during long-term use. However, the lubricant is filled through the gap of the connection end. However, the connection end is relatively tight, and only a small amount of lubricant can be counted into the interior of the tripod, resulting in limited lubrication effect. The overall idea is as follows:

[0023] In response to the problems existing in the prior art, the utility model provides a high-efficiency self-lubricating tripod cylindrical part, including a tripod bracket 11 and a fixed ring 12, a connecting sleeve 13 is rotatably installed inside the fixed ring 12, and at least two support plates 14 are fixedly installed on the side ends of the connecting sleeve 13, and at least two leakage ports 15 are opened at both side ends of the support plate 14, and scrapers 16 are fixedly installed on both side ends of the support plate 14. A fixing block 18 is fixedly installed on the surface of the connecting sleeve 13, and a mounting tube 19 is fixedly installed on the top of the fixing block 18. The lubricant enters the interior of the connecting sleeve 13 through the mounting tube 19. At the same time, the pipeline inside the support plate 14 is connected with the interior of the connecting sleeve 13, and the lubricant enters the interior of the support plate 14 through the connecting sleeve 13. Leakage ports 15 are opened on both sides of the support plate 14. The lubricant enters the interior of the fixing ring 12 through the leakage port 15, and the lubricant flows on the surface of the scraper 16.

[0024] The two side ends of the support plate 14 are rotatably installed with mounting rings 17, the interior of the mounting tube 19 is fixedly installed with a sealing sleeve 21, the interior of the sealing sleeve 21 is slidably installed with a docking tube 22, the top of the docking tube 22 is fixedly installed with two rubber strips 23, and the surface of the docking tube 22 is fixedly installed with two connecting buckles 24, and the top of each connecting buckle 24 is fixedly installed with a telescopic rod 25, allowing the docking tube 22 to slide inside the sealing sleeve 21. At the same time, the docking tube 22 drives the rubber strip 23 to slide downward inside the sealing sleeve 21, and the rubber strip 23 rubs against the inside of the sealing sleeve 21. The docking tube 22 is a multi-layer design, which fits tightly with the inner wall of the sealing sleeve 21. The docking tube 22 moves under force, driving the connecting buckle 24 to move synchronously.

[0025] Working principle:

[0026] In the first step, at least two fixing rings 12 are rotatably installed on the outer side of the tripod 11, and a connecting sleeve 13 is rotatably installed inside the fixing ring 12. A fixed shaft is rotatably installed inside the connecting sleeve 13, and the connecting sleeve 13 drives multiple support plates 14 to fit the surface of the fixed shaft. The inner side of the support plate 14 is an arc-shaped design, which slides and fits with the surface of the fixed shaft. A pipe is installed inside the support plate 14, which runs through the inside of the support plate 14. At the same time, two mounting rings 17 are rotatably installed on the side end of the support plate 14. The mounting ring 17 is arranged inside the fixing ring 12 and fits with the surface of the fixed shaft to facilitate the rotation of the connecting sleeve 13 and the support plate 14. At the same time, a fixing block 18 is installed on the top of the connecting sleeve 13. The top of the fixing block 18 is an inclined surface, and the mounting pipe 19 is installed on the top of the fixed block 18. It is an inclined design to facilitate docking and adding lubricant.

[0027] In the second step, by moving the pipe, aligning one end of the pipe with the fixed block 18, and pushing the material pipe, the material pipe is squeezed on the top of the docking tube 22, allowing the docking tube 22 to slide inside the sealing sleeve 21. At the same time, the docking tube 22 drives the rubber strip 23 to slide downward inside the sealing sleeve 21. The rubber strip 23 and the inner part of the sealing sleeve 21 rub against each other. The docking tube 22 is a multi-layer design and fits tightly with the inner wall of the sealing sleeve 21. The docking tube 22 is forced to move, driving the connecting buckle 24 to move synchronously, allowing the connecting buckle 24 to drive the telescopic rod 25 to slide at the bottom end of the sealing sleeve 21. A torsion spring is installed inside the telescopic rod 25. The movement of 25 pulls the torsion spring to expand and contract, and by pushing the docking tube 22 away from the inside of the sealing sleeve 21, the lubricant enters the inside of the connecting sleeve 13 through the mounting tube 19. At the same time, the pipeline inside the support plate 14 is connected to the inside of the connecting sleeve 13, and the lubricant enters the inside of the support plate 14 through the connecting sleeve 13. Leakage ports 15 are opened on both sides of the support plate 14. The lubricant enters the inside of the fixed ring 12 through the leakage ports 15. The lubricant flows on the surface of the scraper 16. At the same time, the connecting sleeve 13 drives the support plate 14 to be selected inside the fixed ring 12, and the lubricant is applied to the surface of the fixed shaft through the scraper 16.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
