The left end of pipeline 2 is fixedly connected with an entry port 12, and the outside of the entry port 12 is slidably connected to the inside of pipeline 1. A sliding ring 11 is provided on the outside of the entry port 12 to increase the internal fixation, thereby preventing pipeline 2 2 from completely sliding out of the inside of pipeline 1. The inside of pipeline 1 is fixedly connected with a limiting block 13, and the bottom end of the limiting block 13 is slidably connected to the outside of the entry port 12, thereby preventing the entire oil inlet mechanism 10 from deviating. The end of the tension spring 9 away from the fixed ring 5 is fixedly connected to the outside of the pull ring 6, and the outside of the turning handle 1 7 is slidably connected to the inside of the circular ring linkage column 4 to increase the internal fixation.
[0032] Reference Figure 4 and Figure 5The oil inlet mechanism 10 includes a rotating ring 1001, the outer portion of the rotating ring 1001 is rotatably connected to the inside of the pipeline 1, the inner portion of the rotating ring 1001 is fixedly connected to a fixed snap-fit block 1002, the inner portion of the fixed snap-fit block 1002 is fixedly connected to a spring housing 1003, and the inner portion of the spring housing 1003 is slidably connected to a limit ring 1004, the top of the limit ring 1004 is fixedly connected to a thrust spring 1005, the inner portion of the limit ring 1004 is fixedly connected to an injection column 1006, and the end of the thrust spring 1005 away from the limit ring 1004 is fixedly connected to the spring housing 1004. Inside the spring housing 1003, an injection groove 1007 is provided inside the injection column 1006, so that the injection column 1006 is pulled conveniently. After the lubricating oil is dripped into the injection column 1006, the lubricating oil flows into the interior of pipeline 1 1 and pipeline 2 2, thereby increasing the internal flexibility. The interior of the injection column 1006 is slidably connected with an outer cover 1008, and the outside of the outer cover 1008 is fixedly connected with a connecting wire 1009, and the other end of the connecting wire 1009 is fixedly connected to the outside of the injection column 1006, so that the connecting wire 1009 can be inserted into the interior of the injection column 1006 conveniently without dripping the lubricating oil, thereby preventing the entry of dust.
[0033] Working principle: pull the pull ring 6 on the outside of the circular linkage column 4, thereby driving the turning handle 2 8 and the turning handle 1 7 to move, so that the turning handle 2 8 slides into the inside of the fixed block 2 14, and the turning handle 1 7 slides inside the circular linkage column 4, so that the tension spring 9 pulls the pull ring 6, so that the turning handle 2 8 is stuck in the narrow groove of the fixed block 2 14, and the turning handle 1 7 is stuck in the narrow groove of the circular linkage column 4, thereby increasing the internal fixation, facilitating the disassembly of the disassembled joint, increasing the internal fixation to prevent detachment during shaking, saving loading and unloading time and the carrying of tools, thereby reducing maintenance costs and downtime problems. First, pull the connecting line 1009 to drive the injection column 1006 to move inward, thereby opening the outer cover 1008 on the outside of the injection column 1006, so that the lubricating oil is poured into the injection The interior of the injection column 1006 is penetrated by the injection column 1006, thereby flowing into the interior of the pipeline 1 through the injection column 1006, and then the rotating ring 1001 is limited by the limiting block 13 to control the distance and the internal lubrication measurement, so that the lubricating oil enters the sliding part of the pipeline 1 and the pipeline 2 through the sliding ring 11 to prevent rust at the internal rotating part. When the injection column 1006 is pushed by the thrust spring 1005, the outlet of the injection column 1006 and the sliding ring 11 are closed, and the smaller internal air pressure is utilized to make the lubricating oil inside the injection column 1006 no longer flow down, avoiding internal rust, which causes the internal rust to cause the internal jam during loading and unloading or operation, resulting in malfunction. Therefore, the lubrication of the inner wall of the pipeline 1 and the pipeline 2 is increased to avoid malfunction due to internal rust.
