Abstract
The utility model discloses a locking mechanism for a landing door of a construction hoist. When the landing door is locked through the locking mechanism, one end of an adjustment screw is rotated, the other end of the adjustment screw is screwed out to be disengaged from a knocking block, an elastic reset part is loosened, an knocking rod is driven by elastic force released by the elastic reset part to move, so that one end of the knocking rod is disengaged from one end of a door bolt, the other end of the door bolt is located at the horizontal position so as to block the door, and thus the landing door can not be disengaged from a door frame and can be in the closed state all the time. When the landing door is unlocked, one end of the adjustment screw is adjusted, so that the adjustment screw is screwed to be in contact with the knocking block and drives the knocking block to move, the elastic reset part is compressed, one end of the knocking rod abuts against one end of the door bolt at the same time so that the other end of the door bolt can be made to rotate to be located at the vertical position so as to be far away from the position where the landing door is blocked, and then the landing door can enter the door frame to be closed. According to the locking mechanism for the landing door of the construction hoist, when the landing door is locked or unlocked, both the safety and the reliability are high.
