Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to a small door lock safety system for an elevator landing door frame. Background technique [0002] With the growth of the national economy and the development of my country's population aging trend, coupled with the country's increasing attention to national life, domestic elevator installations will soon usher in a large market. Compared with traditional elevators, the installation of ladders often encounters situations where the depth of the pit is small or the height of the top floor is not enough, which will make it difficult for maintenance personnel to obtain sufficient safe-haven space when they are located in the shaft. To solve this problem and the national standard GB / T 28621 - According to the 2012 regulations, measures need to be taken to ensure the safety of maintenance personnel in the shaft when the depth of the pit is insufficient or the height of th...
