specific Embodiment approach

[0010] In the figure, the hall door (6) is equipped with a fixed shaft (4), and one end of the positioning fish (2) rotates around the fixed shaft (4). Block (3), the other end is fish-shaped, and a retaining shaft (1) is installed on the wall, and the retaining shaft (1) is installed at the center 5-10mm away from the hall door. Restricted by the position and size of the retaining shaft (4), it can only be opened by 10-20mm, which restricts the personnel's body from entering the elevator shaft. Since it is opened to a certain width, it is convenient for personnel to visit the position of the elevator car and avoids the absence of the elevator car. The position of the hall door will cause the danger of people falling and avoid the occurrence of safety accidents.

[0011] When the elevator car goes up or down on the same floor as the hall door, when the car door is opened, the door knife (7) drives the wedge (3) to cause the positioning hook (2) to rotate around the fixed shaft...
