Lubricating oil can be added into the oil reservoir 31. When the cylinder 33 is started, it can push the piston 34 to move vertically. The movement of the piston 34 can discharge the lubricating oil in the oil reservoir 31 from the two oil drain pipes 35, so as to lubricate the gap between the hinge shaft 13 and the rotating seat 14, and prevent the door from not turning due to rust. The piston 34 is fixedly connected to both sides of the bottom. A circular plate 61 is fixedly connected to the top of the mounting cavity 32, and a guide rod 62 is fixedly connected to the bottom of the circular plate 61. Through holes 63 are respectively opened on both sides of the top of the mounting cavity 32. The guide rod 62 is slidably connected to the through holes 63. The movement of the piston 34 can drive the circular plate 61 to move, which in turn can drive the guide rod 62 to move.

An oil inlet pipe 71 is fixedly connected to one side of the top of the oil reservoir 31. A sealing plug 72 is screwed to the top of the oil inlet pipe 71. The oil inlet pipe 71 can easily add lubricating oil into the oil reservoir 31. The sealing plug 72 can be screwed to the top of the oil inlet pipe 71 to seal it and prevent lubricating oil leakage.

[0027] Working principle: During operation, unscrew the sealing plug 72, then add lubricating oil into the oil reservoir 31 through the oil inlet pipe 71. Then, screw the sealing plug 72 onto the top of the oil inlet pipe 71. According to the door requirements, pull the pull plate 25. The movement of the pull plate 25 moves the positioning rod 24, simultaneously deforming the spring 26. The positioning rod 24 can then disengage from the current positioning hole 22. At this point, the door mounting seat 11 can be pulled to adjust it to a suitable position. Then, release the pull plate 25. The spring 26 returns to its original position, pushing the positioning rod 24 back to its original position, allowing it to insert into the positioning hole 22 for adjustment. The rear door mounting seat 11 is fixed, and then the body mounting seat 1 is fixed to the door. When the hinge shaft 13 needs to be lubricated, the cylinder 33 is activated. The operation of the cylinder 33 can push the piston 34 to move vertically. The movement of the piston 34 can push the lubricating oil to move, so that the lubricating oil can be discharged from the oil drain pipe 35, so as to lubricate the hinge shaft 13 and the rotating seat 14, and avoid the door from not being able to turn due to corrosion. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
