[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a formal elevator door protection device during the decoration construction stage, including a protective plate 1 and an elevator 2. The elevator 2 is provided with a double-opening elevator door 3. The protective plate 1 includes a fixed section 4, a spanning section 5 and a slope section 6. The fixed section 4, the spanning section 5 and the slope section 6 are respectively hinged to each other through a metal hinge 7. The fixed section 4 is placed inside the elevator 2, the spanning section 5 is placed on the groove of the elevator door 3, and the slope section 6 is placed outside the elevator 2.
[0023] Refer to Figures 2-3 , fixed rings 8 are fixedly provided on both sides of the top end of the spanning section 5. Connecting pull ropes 9 are arranged on the fixed rings 8. The two connecting pull ropes 9 are twisted into a single rope in cooperation with the connecting ring 10. Workers can manually grasp the connecting pull ropes 9. Therefore, by pulling the connecting pull ropes 9, the spanning section 5 and the slope section 6 can be retracted into the elevator to ensure the normal operation of the elevator.
[0024] Refer to Figures 1-4, the fixed section 4, the spanning section 5, and the slope section 6 each include a left side plate 11, a middle plate 12, and a right side plate 13. On both sides of the middle plate 12, there are step chutes 14. On both the left side plate 11 and the right side plate 13, there are fixed sliding plates 15. The sliding plates 15 are arranged in the step chutes 14. On the side walls of the sliding plates 15 on both the left side plate 11 and the right side plate 13, there are engraved scale lines 16. On both the left side plate 11 and the right side plate 13, there are fixed multiple telescopic rods 17. On the middle plate 12, there is a setting groove 18. The other end of the telescopic rod 17 penetrates into the corresponding setting groove 18, and the other end of the telescopic rod 17 is fixed to the inner end face of the setting groove 18. On both the left side plate 11 and the right side plate 13 of the fixed section 4 and the slope section 6, there is fixed a square long rod 19. On the middle plate 12 of the fixed section 4 and the slope section 6, there is a long rod chute 20. The square long rod 19 extends into the long rod chute 20. On the side wall of the middle plate 12, there is a threaded fastening screw 21. The end of the fastening screw 21 abuts against the square long rod 19. The fixed section 4, the spanning section 5, and the slope section 6 are all composed of the left side plate 11, the middle plate 12, and the right side plate 13. And the left side plate 11, the middle plate 12, and the right side plate 13 can be adjusted, so as to increase the overall length of the fixed section 4, the spanning section 5, and the slope section 6, making the width of the protection plate the same as the width of the elevator door opening, and increasing the practicality of its protection measures. The sliding plate 15 can slide on the step chute 14. And during the movement process, the telescopic rod 17 performs an elongation movement. The other end of the telescopic rod 17 is fixed to the inner end face of the setting groove 18, ensuring that the left side plate 11, the middle plate 12, and the right side plate 13 are connected as a whole and have a length adjustment function. During the adjustment process, the designed square long rod 19 slides in the long rod chute 20. After the adjustment is completed, then manually rotate the fastening screw 21.
