[0034] The elevator shaft passageway protection structure is used to protect the passageway during elevator construction. When installing the protection structure, first adjust it according to the opening of the elevator shaft passageway, such as Figure 1 As shown, the warning plate 2 installed on the front surface of the outer frame 1 can serve as a danger warning, and the protective net installed between the outer frames 1 can further provide protection to prevent building materials from accidentally falling from the passage. Figure 2 As shown, a fixed cylinder 1 3, a fixed cylinder 2 4 and a vertical cylinder 9 are fixedly installed on the rear surface of the outer frame 1. When the overall width is adjusted, the extension rod 1 5 and the hole-opening rod 1 6 are slid and pulled out from the side surfaces of the fixed cylinder 1 3 and the fixed cylinder 2 4. When the appropriate position is reached, the connecting cylinder 7 connected to one end of the extension rod 1 5 and the hole-opening rod 1 6 moves at the same time, and the extension rod 2 8 is driven to move through the connecting cylinder 7, thereby changing the width distance between the extension rod 2 8 and the hole-opening rod 2 10. A telescopic rod 11 is fixedly connected to the upper end of the extension rod 2 8. The telescopic rod 11 will be pulled up by the extension rod 8. After the width is adjusted to be appropriate, the connecting piece 18 on the outer surface of the vertical tube 9 and the connecting tube 7 is fixed to the wall of the elevator shaft passage through bolts, and then the height is adjusted, and the telescopic rod 11 is pushed upward a little, so that the telescopic rod 11 drives the extension rod 8 and the opening rod 10 to slide upward from the connecting tube 7 and the vertical tube 9 respectively, and then after reaching the appropriate height, the connecting piece 18 installed on the outer surface of the telescopic rod 11 is fixedly connected to the wall through bolts, which improves the versatility of the structure and is more flexible to use.

Figure 6 As shown, the rotating ring 13 is then rotated so that the rotating ring 13 closes the upper end of the hole of the opening rod 16, so that the reinforcement rod 12 is more stable, and a reinforcement rod 12 of suitable length is selected between the opening rod 10 and the extension rod 8, so that one end of the reinforcement rod 12 passes through the opening rod 10, and the other end is inserted into the slot of the extension rod 8, and then the rotating ring 13 on the outer surface of the opening rod 10 is rotated to close the hole. Furthermore, a fixing plate 16 fixedly installed on the side surface of the outer frame 1 is threadedly connected with a threaded rod 17.
