Abstract

The invention relates to a device and method for blocking a human body when an elevator landing door is not normally opened. The device comprises a blocking start part and a blocking part. The blocking start part is composed of a large rotating disc, a small rotating disc, a pawl tripping mechanism, a rotating disc push rod and a starting part base, wherein the large rotating disc and the small rotating disc are connected with pawls respectively, and pawl tripping opening hooks are arranged below the pawls. The blocking part is composed of a locking hook, a blocking piece and a blocking part base. The method includes the steps that firstly, people can not enter an elevator cage when the elevator cage is not on a certain landing and the landing door of the landing is not normally opened, and therefore the safety protection effect is achieved; when the elevator cage arrives at the certain landing, the normal use of an elevator is not influenced. The casualty accident that people fall off a building from the landing door of the elevator can be prevented, and potential safety hazards can be eliminated; due to the mechanical blocking structure, blocking is visible and reliable.
