The bushing body 100 includes an outer side wall 101 and an inner side wall 102, and the bushing body 100 is formed by rolling a straight strip of raw material. The lubrication mechanism 200 includes a main oil storage cavity 201 opened inside the outer side wall 101 and eight auxiliary oil storage grooves 202 equidistantly opened on the inner annular surface of the inner side wall 102. The inner wall of the auxiliary oil storage grooves 202 is circumferentially arranged with four radial capillary oil delivery tubes 203 equidistantly.

The lubrication mechanism 200 also includes a number of sets of micro oil storage grooves 204 equidistantly opened on the inner side wall 102.

[0037] Specifically, by setting up the bushing body 100 and the lubrication mechanism 200, the lubricating oil in the main oil storage chamber 201 can enter the auxiliary oil storage tank 202 through the radial capillary oil supply pipe 203 to lubricate the friction surface of the bushing body 100. During the lubrication process, excess lubricating oil can be stored in the micro oil storage tank 204 to achieve long-term continuous lubrication. Furthermore, during frictional rotation, the oil supply can be dominated by capillary action.

[0041] Specifically, lubricating oil can be easily added into the main oil reservoir 201 through the oil filling hole 205.

[0042] Please refer to this carefully. Figure 2 , Figure 3 The bushing body 100 has three snap-fit ​​protrusions 103 at one end, and a slot 104 adapted to the snap-fit ​​protrusions 103 is provided at the other end of the bushing body 100.

[0043] Specifically, the overall strength of the bushing body 100 is effectively improved by the action of the snap-fit ​​protrusion 103 and the snap-fit ​​groove 104.

[0044] In this embodiment, by setting up a bushing body 100 and a lubrication mechanism 200, the lubricating oil in the main oil storage chamber 201 can enter the auxiliary oil storage tank 202 through the radial capillary oil supply pipe 203 to lubricate the friction surface of the bushing body 100 during actual use. During the lubrication process, excess lubricating oil can be stored in the micro oil storage tank 204 to achieve long-term continuous lubrication. Moreover, it can lubricate the friction surface evenly. At the same time, during friction rotation, it can dominate the oil supply through capillary action, and the maintenance cycle is extended, reducing the frequency of oiling and maintenance. Furthermore, the structure is simple and the manufacturing cost is low.

[0045] Example 2 Based on Example 1, referring to Figures 5 to 9 And unlike Example 1, the following is true: Please refer to this carefully. Figure 5 , Figure 6 The end of the bushing body 100 is provided with a locking mechanism 300 for locking the three snap-fit ​​protrusions 103.

[0046] Specifically, the locking mechanism 300 can effectively lock the snap-fit ​​protrusion 103.

[0047] Please refer to this carefully. Figure 6 , Figure 7 The locking mechanism 300 includes an insertion hole 301 at the end of the inner wall 102 of the bushing body 100. The insertion hole 301 passes through the inner wall 102 and three snap-fit ​​protrusions 103. An insertion post 302 is inserted into the inner wall of the insertion hole 301. A rotating block 303 is fixed at one end of the insertion post 302. A first hexagonal operating groove is opened on the surface of the rotating block 303. A first recessed groove is opened at the end of the inner wall 102, which is adapted to the rotating block 303 and rotatably connected to the outer surface of the rotating block 303. An internal thread locking cylinder 304 is provided at the other end of the insertion post 302. A second hexagonal operating groove is opened at the end of the internal thread locking cylinder 304. A second recessed groove is opened at the other end of the inner wall 102, which is adapted to the internal thread locking cylinder 304 and rotatably connected to the outer surface of the internal thread locking cylinder 304.

[0048] Specifically, the plug post 302 can be inserted into the plug hole 301, so that the plug post 302 passes through the three snap-fit ​​protrusions 103, effectively ensuring the stability of the bushing body 100 during use.

[0049] Please refer to this carefully. Figure 6 , Figure 7 The outer surface of the end of the plug-in post 302 away from the rotating block 303 is threaded, and the end of the plug-in post 302 away from the rotating block 303 is threadedly connected to the inner wall of the internal thread locking cylinder 304.

[0050] Specifically, after the plug post 302 passes through the three snap-fit ​​protrusions 103, the internal thread locking sleeve 304 is tightened onto the end of the plug post 302 to effectively lock the snap-fit ​​protrusions 103.

[0051] In this invention, by setting a locking mechanism 300, after the bushing body 100 is processed and formed, the plug pin 302 can be inserted into the plug hole 301, and after the plug pin 302 passes through the three snap-fit ​​protrusions 103, the internal thread locking cylinder 304 is tightened on the end of the plug pin 302, thereby effectively locking the snap-fit ​​protrusions 103, thus effectively ensuring the stability of the bushing body 100 during use and reducing the probability of deformation.

[0052] Please refer to this carefully. Figure 8 , Figure 9 The snap-fit ​​protrusion 103 is provided with a reinforcing mechanism 400. The reinforcing mechanism 400 includes a rectangular cavity 401 opened inside the snap-fit ​​protrusion 103, a cylindrical hole 402 opened on the inner wall of the rectangular cavity 401 and extending to the outer surface of the snap-fit ​​protrusion 103, a locking post 403 slidably arranged on the inner wall of the cylindrical hole 402, and a locking groove 404 opened on the inner wall of the snap-fit ​​groove 104 that is adapted to the locking post 403 and slidably connected to the outer surface of the locking post 403.

[0053] Specifically, the locking pin 403 can be inserted into the locking groove 404 in the slot 104 to effectively reinforce the engagement between the protrusion 103 and the slot 104.

[0054] Please refer to this carefully. Figure 8 , Figure 9 A connecting plate 405 is fixedly provided at the end of the locking post 403, and an ejector spring 406 is sleeved on the outer surface of the locking post 403. The two ends of the ejector spring 406 are fixedly connected to the surface of the connecting plate 405 and the inner wall of the rectangular cavity 401, respectively. A rotating shaft 407 is rotatably provided on the inner wall of the rectangular cavity 401. A limiting frame 408 for limiting the connecting plate 405 is fixedly provided on the surface of the rotating shaft 407. Two symmetrical torsion springs 409 are sleeved on the surface of the rotating shaft 407. One end of the torsion spring 409 is fixedly connected to the inner wall of the rectangular cavity 401, and the other end of the torsion spring 409 is fixedly connected to the surface of the limiting frame 408.

[0055] Specifically, after the plug-in pin 302 is inserted into place, the external hex wrench can be used to rotate the rotating block 303 to drive the plug-in pin 302 to rotate. The rotation of the plug-in pin 302 drives the toggle block 4010 to rotate. During the rotation of the toggle block 4010, the toggle block 4010 can squeeze the end of the limit frame 408, causing the limit frame 408 to rotate around the rotating shaft 407, so that the other end of the limit frame 408 is disengaged from the connecting plate 405. At this time, the connecting plate 405 and the locking pin 403 can be ejected outward under the action of the ejection spring 406.

[0056] Please refer to this carefully. Figure 8 , Figure 9 The outer surface of the plug post 302 is fixed with equidistant levers 4010 corresponding to the three rectangular cavities 401. The inner wall of the plug hole 301 is provided with a rectangular inclined hole 4011 that penetrates the inner side wall 102 of the bushing body 100. The three levers 4010 are slidably connected to the inner wall of the rectangular inclined hole 4011.

[0057] Specifically, during the process of inserting the plug 302 into the plug hole 301, the plug 302 can be inserted at a specific angle under the action of the toggle block 4010 and the rectangular inclined hole 4011.

[0058] Please refer to this carefully. Figure 10 The outer surface of the locking post 403 is fixed with a pressure block 4012. The inner wall of the cylindrical hole 402 is provided with a pressure groove for the pressure block 4012 to slide. The inner wall of the pressure groove is fixed with an inflatable airbag ring 4013. The inner wall of the cylindrical hole 402 is also provided with a sealing groove 4014. A sealing plate 4015 is slidably provided on the inner wall of the sealing groove 4014. A positioning post 4016 is fixed on the surface of the sealing plate 4015. The outer surface of the locking post 403 is provided with a positioning groove 4017 that matches the positioning post 4016. The surface of the inflatable airbag ring 4013 is provided with a connecting tube extending into the sealing groove 4014.

[0059] Specifically, during the movement of the locking pin 403, the pressure block 4012 can be driven to squeeze the inflatable airbag ring 4013, allowing the gas inside the inflatable airbag ring 4013 to enter the sealing groove 4014, driving the sealing plate 4015 and the positioning pin 4016 to move outward. When the positioning pin 4016 corresponds to the positioning groove 4017, the positioning pin 4016 can automatically insert into the positioning groove 4017, thereby achieving effective locking and positioning of the locking pin 403.

[0060] In this invention, by setting a reinforcing mechanism 400, during the process of inserting the plug 302 into the plug hole 301, the plug 302 can be inserted at a specific angle under the action of the lever 4010 and the rectangular inclined hole 4011. After the plug 302 is inserted in place, the external hexagonal wrench can rotate the rotating block 303 to drive the plug 302 to rotate. The rotation of the plug 302 drives the lever 4010 to rotate. During the rotation of the lever 4010, the lever 4010 can squeeze the end of the limiting frame 408, causing the limiting frame 408 to rotate around the rotating shaft 407, so that the other end of the limiting frame 408 disengages from the connecting plate 405. At this time, the connecting plate 405 and the locking pin 403 can be spring-loaded. The locking pin 403 is ejected outward under the action of the spring 406, allowing it to be inserted into the locking groove 404 within the slot 104. This effectively reinforces the engagement protrusion 103 and the slot 104, ensuring the stability of the connection between them. Furthermore, as the locking pin 403 moves, it drives the pressure block 4012 to compress the inflatable airbag ring 4013, allowing the gas inside the ring to enter the sealing groove 4014. This drives the sealing plate 4015 and the positioning pin 4016 to move outward. When the positioning pin 4016 aligns with the positioning groove 4017, it automatically inserts into the groove, effectively locking and positioning the locking pin 403.

[0061] Working principle: In actual use, the lubricating oil in the main oil reservoir 201 can enter the auxiliary oil reservoir 202 through the radial capillary oil supply pipe 203 to lubricate the friction surface of the bushing body 100. During lubrication, excess lubricating oil can be stored in the micro oil reservoir 204, achieving long-term continuous lubrication. It also provides uniform lubrication to the friction surface, extends the maintenance cycle, and reduces the frequency of oiling and maintenance. Furthermore, during frictional rotation, it can control oil supply through capillary action. The structure is simple and the manufacturing cost is low. After the bushing body 100 is formed, the insertion post 302 can be inserted into the insertion hole 301, allowing the insertion post 302 to penetrate the three snap-fit ​​protrusions 10. After step 3, tighten the internal thread locking sleeve 304 onto the end of the plug pin 302 to effectively lock the snap-fit ​​protrusion 103, thereby effectively ensuring the stability of the bushing body 100 during use and reducing the probability of deformation. Simultaneously, once the plug pin 302 is in place, the external hex wrench can be used to rotate the rotating block 303, causing the plug pin 302 to rotate. The rotation of the plug pin 302 causes the lever block 4010 to rotate. During the rotation of the lever block 4010, it can press against the end of the limiting bracket 408, causing the limiting bracket 408 to rotate around the rotating shaft 407, disengaging the other end of the limiting bracket 408 from the connecting plate 405. At this time, the connecting plate 405 and the locking pin 403 can be ejected... Under the action of spring 406, the plug 302 is ejected outwards and inserted into the plug hole 301. During this process, the plug 302 can be inserted at a specific angle under the action of the lever 4010 and the rectangular inclined hole 4011. After the plug 302 is inserted into place, the external hexagonal wrench can be used to rotate the rotating block 303 to drive the plug 302 to rotate. The rotation of the plug 302 drives the lever 4010 to rotate. During the rotation of the lever 4010, the lever 4010 can squeeze the end of the limiting frame 408, causing the limiting frame 408 to rotate around the rotating shaft 407, so that the other end of the limiting frame 408 is disengaged from the connecting plate 405. At this time, the connecting plate 405 and the locking pin 403 can be ejected. The spring 406 ejects the locking pin 403 outward, allowing it to insert into the locking groove 404 within the slot 104. This effectively reinforces the engagement protrusion 103 and the slot 104, ensuring the stability of the connection between them. Furthermore, as the locking pin 403 moves, it drives the pressure block 4012 to compress the inflatable airbag ring 4013, allowing the gas inside the ring to enter the sealing groove 4014. This drives the sealing plate 4015 and the positioning pin 4016 outward. When the positioning pin 4016 aligns with the positioning groove 4017, it automatically inserts into the groove, effectively locking and positioning the locking pin 403.
