[0037] Working principle: A plurality of balls are arranged inside the civil air defense door 2. By pulling the handle 3, the handle 3 can drive the civil air defense door 2 to slide inside the installation groove 1. The motor 5 drives the cam 6 to rotate. The cam 6 abuts against the sliding block 7 and intermittently pushes the sliding block 7 to slide inside the oil tank 4. At the same time, the sliding block 7 pulls the tension spring 8, and the tension spring 8 generates a pulling force. When the sliding block 7 slides, it pushes the lubricating oil inside the oil tank 4 to be transported to the top inside of the installation groove 1 through the upper output pipe 10 and to the bottom inside of the installation groove 1 through the lower output pipe 11 to lubricate the balls inside the installation groove 1. Check valves 12 are arranged inside the upper output pipe 10 and the lower output pipe 11, so that the upper output pipe 10 and the lower output pipe 11 can only discharge oil and cannot intake oil, preventing the lubricating oil from flowing back. When the sliding block 7 does not abut against the cam 6, the sliding block 7 is pulled back to its original position by the tension spring 8. At the same time, the lubricating oil is sucked into the oil tank 4 through the oil inlet pipe 9. A check valve 12 is arranged inside the oil inlet pipe 9, so that the oil inlet pipe 9 can only intake oil and cannot discharge oil, preventing the lubricating oil from being squeezed out through the oil inlet pipe 9 when the sliding block 7 is intermittently pushed by the cam 6. When the civil air defense door 2 is impacted, the force-bearing plate 19 pushes the damping rod 20. At the same time, the force-bearing plate 19 drives the connecting rod 18. The connecting rod 18 transmits the impact force received by the force-bearing plate 19 to the movable block 17. The movable block 17 slides on the outer side of the civil air defense door 2 and the outer circumference of the sliding rod 15. When the movable block 17 slides, it compresses the spring 16. The elastic force of the spring 16 and the damping force of the damping rod 20 buffer the impact force received by the force-bearing plate 19 to protect the civil air defense door 2.
