When the pull rope is loosened, the sliding door panel will drive the sliding block to move inward through the spring, and the rotating rod will rotate, thereby driving the sliding door panel to move up through the top plate, and the push protection plate will rotate to protect the direction above the worker's head;

[0016] S2: When an object falls onto the rotating plate, a downward pressure is generated, which drives the rotating plate to rotate and drives the trapezoidal sliding block to move together.

When the strong wind passes through the diverter plate, the diverter plate will disperse it into multiple small wind flows, reducing the impact of wind on the protective mechanism.

[0019] The utility model has the following beneficial effects:

[0020] (1) According to the utility model, when the pull rope of the sliding door panel is loosened, the sliding block 1 is driven by the spring to move inward, and when the sliding block 1 moves inward, the rotating rod is rotated, and when the rotating rod is rotated, the top plate is pushed to move upward, and when the fixed block moves upward, the sliding door panel is driven upward, and when the sliding door panel moves upward, the fixed block pushes the sliding block 2 to slide in the slide groove at the top of the protective plate, and pushes the protective plate to rotate, thereby protecting the workers from the head, reducing the damage to the workers caused by falling objects, and reducing the losses such as downtime and compensation caused by accidents.

[0021] (2) According to the utility model, when an object falls from a high altitude, the object will first contact the rotating plate. Since the rotating plate is inclined, the object will generate a downward pressure when it falls on the rotating plate, thereby driving the rotating plate to rotate. When the rotating plate rotates, it will drive the trapezoidal sliding block to move together, and move the connecting block downward by squeezing the trapezoidal sliding block. When the connecting block moves downward, it will drive the pressure plate to move downward inside the air pressure box and squeeze the gas inside the air pressure box. During the compression process, the gas inside the air pressure box will convert the impact force generated by the falling object into a compression force, which plays a buffering role, preventing the object falling from a high altitude from falling directly on the protective plate, thereby causing damage to the protective plate, reducing the impact and vibration of the device, thereby extending its service life and reducing the cost caused by frequent maintenance or replacement.

[0022] (3) According to the utility model, when the sliding door panel rises, the fixed block drives the sliding block 2 to move inward relative to the protective plate. When the sliding block 2 moves, it pulls the top rod through the vertical plate and causes it to rotate. When the top rod rotates, it pulls the movable plate to move downward. When the movable plate moves downward, it causes the push plate to rotate. When the push plate rotates, it pushes the wind guide plate to rotate. In strong wind weather, the wind direction is guided, and the impact caused by direct contact between the wind and the protective mechanism in strong wind weather is reduced, which helps to extend the service life of the protective mechanism, reduce the direct effect of wind on the material, and reduce the fatigue and wear of the material, thereby reducing the frequency of maintenance and replacement.

[0023] (4) In the utility model, when strong wind changes its direction through the wind guide plate, it will also pass through the diverter plate. The different directions of the strong wind will drive the diverter plate to rotate in different directions. When the diverter plate rotates, it will drive the rotating block to rotate, and the rotating block will drive the moving block to rotate together. The direction of rotation of the diverter plate is limited by the spring and the support plate. When strong wind passes through the diverter plate, the diverter plate will disperse it into multiple small wind flows, further reducing the direct impact of wind on the protective mechanism, enhancing the protective effect of the protective device in strong wind weather, and also improving the stability of the elevator passage.

When the fixed block 307 moves inward, the top plate 303 will move upward. When the sliding door panel 301 moves upward, the fixed block 307 will push the sliding block 308 to slide in the slide groove at the top of the protective plate 309, and push the protective plate 309 to rotate, so as to protect the direction above the worker's head. When objects fall from the sky, the objects will first contact with the rotating plate 401. Since the rotating plate 401 is inclined, the objects will generate a downward pressure when they fall on the rotating plate 401, thereby driving The rotating plate 401 rotates, and the rotating plate 401 drives the trapezoidal sliding block 402 to move together, and the trapezoidal sliding block 402 squeezes the connecting block 403 to move downward. When the connecting block 403 moves downward, it drives the pressing plate 404 to move downward inside the air pressure box 405, and squeezes the gas inside the air pressure box 405. The gas inside the air pressure box 405 converts the impact force generated by the falling object into compression force during the compression process, which plays a buffering role. When the impact force dissipates,The trapezoidal block 408 will move inward under the reaction force of the spring, and the trapezoidal block 408 will cause the push rod 407 to rotate when moving, and push the rotating plate 401 to rotate so that the rotating plate 401 returns to its original position. When the sliding door panel 301 rises, the fixed block 307 will drive the second sliding block 308 to move inward relative to the protective plate 309. When the sliding block 308 moves, it will pull the top rod 503 through the vertical plate 504 and cause it to rotate. When the top rod 503 rotates, it will pull the movable plate 502 to move downward. When the movable plate 502 moves downward, it will cause the push plate 506 to rotate, and the push plate 506 will rotate when it rotates. When the wind guide plate 505 is rotated, the wind direction is guided in strong wind weather. When the strong wind passes through the wind guide plate 505 and changes the wind direction, it will pass through the diverter plate 602. The direction of rotation of the diverter plate 602 will be different depending on the direction of the strong wind. When the diverter plate 602 rotates, it will drive the rotating block 603 to rotate, and the rotating block 603 drives the moving block 604 to rotate together. The direction of rotation of the diverter plate 602 is limited by the spring and the support plate 605. When the strong wind passes through the diverter plate 602, the diverter plate 602 will disperse it into multiple small wind flows, further reducing the direct impact of the wind on the protective mechanism 3.
