[0019] See also Figure 1-3 As shown, a self-lubricating structure of a pin connected on a hydraulic support includes a rotating rod 1, a rotating rod 2 and a pin 3. The rotating rod 1 and the rotating rod 2 are rotatably connected through the pin 3. An oil box 4 is fixedly installed at one end of the pin 3. A gasket 5 is also rotatably arranged on the pin 3. The gasket 5 is arranged between the rotating rod 1 and the oil box 4.

[0020] The oil box 4 is provided with an oil outlet hole 9, and the oil leakage hole 8 cooperates with the oil outlet hole 9. There are six oil leakage holes 8 and six oil outlet holes 9. The pin shaft 3 is threaded with an oil groove 10 for the flow of lubricating oil. The oil leakage hole 8 contacts one end of the oil groove 10, so that the lubricating oil in the oil leakage hole 8 flows into the oil groove 10. The end of the pin shaft 3 away from the oil box 4 is also slidably provided with a collecting box 11 for receiving excess lubricating oil. The collecting box 11 is provided with an oil receiving hole 12 for collecting lubricating oil. After the rotation of the rotating rod 2 is completed, the rotating rod 1 is relatively fixed to the rotating rod 2, and the pin shaft 3 is rotated alone so that the oil outlet hole 9 on the oil box 4 does not cooperate with the oil leakage hole 8, so as to avoid the waste caused by continuous leakage of lubricating oil.

[0021] The clamping member 7 includes a connecting plate 13, a spring 14 and a clamping pad 15. The end of the connecting rod 6 away from the gasket 5 is rotatably connected to the connecting plate 13. The spring 14 is fixedly installed on both ends of the connecting plate 13. Two clamping pads 15 are provided. The two clamping pads 15 are respectively fixedly connected to the two ends of the connecting plate 13 through the spring 14. The clamping pads 15 are clamped on both sides of the rotating rod 1, and the clamping pads 15 are rubber pads, which increase the friction between the clamping pads 15 and the rotating rod 1, and have a better effect on fixing the position of the gasket 5.

[0022] A vertical rod 16 is rotatably mounted on one end of the oil box 4 away from the pin shaft 3, a cross bar 17 is fixedly mounted on the vertical rod 16, a cross bar 2 18 is rotatably mounted on the collection box 11, and a hydraulic rod 19 is fixedly connected between the cross bars 17 and 18 for controlling the collection box 11 to slide on the pin shaft 3.

[0023] An adjustment component 20 for controlling the angle of the hydraulic rod 19 is also provided on the end of the oil box 4 away from the pin shaft 3. The adjustment component 20 cooperates with the vertical rod 16. The adjustment component 20 includes a motor 21, a gear 1 22 and a gear 2 23.

[0024] When the utility model is in use, when the pin shaft 3 is used, the pin shaft 3 is inserted into the circular holes provided on the rotating rod 1 and the rotating rod 2, so that the rotating rod 1 and the rotating rod 2 are rotatably connected, and at this time, the oil box 4 is rotated to rotate the connecting rod 6 to be parallel to the rotating rod 1, and the spring 14 is pulled to increase the distance between the clamping pads 15 to match the rotating rod 1, and the clamping pads 15 are clamped on the rotating rod 1, so that the gasket 5 is fixed relative to the rotating rod 1, and the rotating rod 2 is rotated relative to the rotating rod 1. At this time, the position of the gasket 5 is If it does not change, the pin 3 and the rotating rod 2 2 rotate, and the oil outlet hole 9 provided on the oil box 4 fixedly mounted on the pin 3 cooperates with the oil leakage hole 8 during rotation, so that the lubricating oil in the oil box 4 leaks out and falls into the threaded oil groove 10, so as to lubricate the connection between the pin 3 and the rotating rod 1 and the rotating rod 2, thereby realizing the self-lubrication of the pin 3. When in use, the position of the collecting box 11 can also be adjusted by opening the hydraulic rod 19. When the pin 3 needs to be removed, the collecting box 11 is slid away from the pin 3 to facilitate the removal of the pin 3.

[0025] The position of the hydraulic rod 19 can also be adjusted by turning on the motor 21. When the motor 21 is started, the motor 21 controls the gear 1 22 to rotate, and the gear 1 22 drives the gear 2 23 to rotate. The gear 2 23 drives the vertical rod 16 to rotate relative to the oil box 4 to adjust the angle of the hydraulic rod 19 so that the hydraulic rod 19 does not interfere with the rotating rod 1 1 and the rotating rod 2 2.
