[0022] like Figure 4 As shown, the bottom wall of the oil bin 5 is fixed with a limit frame 12 near both sides of the sealing end block 8, and a limit column 10 is slidably provided on the limit frame 12. The bottom end of the limit column 10 is fixedly connected to the top wall of the sealing end block 8, and a spring 11 is provided on the outer sleeve of the limit column 10. The upper and lower ends of the spring 11 are respectively fixed on the bottom wall of the limit frame 12 and the top wall of the sealing end block 8. The movable block 7 rises to drive the sealing end block 8 and the limit column 10 to rise, the spring 11 is compressed, the sealing end block 8 opens the oil outlet 6, and the lubricating oil falls out of the oil outlet 6 for lubrication. A pushing block 9 is fixed on the chain 14. The longitudinal sections of the top of the pushing block 9 and the bottom of the movable block 7 are both isosceles triangles. The pushing block 9 can push the movable block 7 left and right to make the lubricating oil fall out of the oil outlet 6.

[0023] like Figure 2 , 3As shown, the driving mechanism 3 includes a driving motor 13, which is fixed on the side wall of the mounting shell 2. A driving sprocket 15 is fixedly connected to the driving motor 13. A driven sprocket 16 is rotatably provided at one end of the mounting shell 2 away from the driving motor 13. A chain 14 is provided on the driving sprocket 15 and the driven sprocket 16. A fixed top plate 2 18 and a fixed top plate 1 17 fixed to a connecting top block 20 are respectively fixed on the upper and lower parts of the chain 14. The driving motor 13 drives the driving sprocket 15 to rotate, thereby driving the fixed top plate 1 17 and the fixed top plate 2 18 to move closer to or away from each other, thereby driving the opening and closing of the radiation protection door 21. An external plate 24 is provided under the chain 14 in the mounting shell 2, and an oil absorbing sponge 23 is provided on the external plate 24. The oil absorbing sponge 23 is closely attached to the chain 14, and the oil absorbing sponge 23 absorbs the dripping lubricating oil and applies the lubricating oil to the chain 14 at the same time.

[0024] During specific use, the driving motor 13 drives the driving sprocket 15 to rotate, and the driving sprocket 15 drives the chain 14 and the driven sprocket 16 to rotate. The rotation of the chain 14 drives the fixed top plate 17 and the fixed top plate 2 18 to move closer to or away from each other, thereby driving the radiation protection door 21 to open and close; in the process of the movement of the chain 14, it drives the pushing block 9 to move, and the pushing block 9 pushes the movable block 7, so that the movable block 7 moves upward. The rise of the movable block 7 drives the sealing end block 8 and the limiting column 10 to rise, and the spring 11 is compressed, and the sealing end block 8 opens the oil outlet 6, and the lubricating oil falls out of the oil outlet 6 for lubrication. When the pushing block 9 is away from the movable block 7, the restoring force of the spring 11 itself makes the sealing end block 8 return to its original position, and the oil outlet 6 is sealed. The oil-absorbing sponge 23 absorbs the dripping lubricating oil, and at the same time applies the lubricating oil to the chain 14, so as to ensure the flexibility of the movement of the radiation protection door 21 and reduce noise.

[0025] The above description of the utility model and its implementation methods is not restrictive.
