[0036] Compared with most traditional KFC door bushings, this KFC door bushing is provided with two polyurethane buffer blocks 307 on the main door bushing 303. When the KFC door shaft 4 controls the rotation of the rotating shaft 308, when it reaches a near right angle, the shift block 309 will touch the main door bushing 303 and squeeze the buffer block 307, thereby reducing the impact force, reducing the damage to the KFC door caused by forceful door opening, reducing door wear, and extending the service life of the door. Under the action of the weight of the door panel, pressure is applied to the buffer block 307, and the pressure is released when the door is closed, thereby reducing the force required to shift the door panel, thereby improving the convenience of using the KFC door bushing.

[0037] The receiving groove 301 is opened in the middle of the upper surface of the mounting shell 1, so that the door lining mechanism 3 can be fixed in the desired position by the mounting shell 1. The inner wall of the receiving groove 301 is provided with a plurality of positioning grooves 302, and the outer wall of the main door lining 303 is fixedly connected with a plurality of positioning blocks 304, so that the position of the main door lining 303 in the receiving groove 301 can be fixed and limited, thereby reducing the possibility of deformation caused by the rotating shaft 308, and the shift block 309 slides inside the limiting groove 305, so that the shift block 309 can engage with the buffer block when the door panel is opened. 307 is in contact, a threaded groove 3011 is provided on the periphery of the upper surface of the mounting shell 1, and the inner wall thread of the threaded groove 3011 is matched with a cover plate 3012, so that the cover plate 3012 can be threadedly fixed on the mounting shell 1, thereby protecting the main door bushing 303, an oil filling port 3013 is provided at the rear end of the middle part of the upper surface of the mounting shell 1, and an oil storage tank 3014 is provided in the middle of the inner wall of the oil filling port 3013, and the user can inject lubricating oil into the oil storage tank 3014 through the oil filling port 3013, and it is used as the rotating shaft 308 rotates.
