Abstract

An automatic blocking mechanism of door leaf is featured as connecting rubber door leaf swing around shaft to electromagnetic jaw clutch, setting DC speed reducing motor and angle control device on installation base. The blocking mechanism can be switched no automatically to avoid the door leaf to be operated by outside force when electric power is off.

Description

technical field [0001] The invention relates to an automatic fare collection system at rail transit stations, in particular to a door blocking mechanism used on automatic ticket gates for entering and exiting stations. Background technique [0002] On the urban rail transit automatic ticket gate, a blocking device must be used to control the passage of passengers. [0003] At present, there are two types of trident stoppers and door leaf stoppers that are often used. Because the door-type barrier has the characteristics of fast pedestrian passing, it has been widely used in automatic ticket gates at rail transit stations. [0004] Door-type stoppers are divided into three types: vertical-axis rotating flapping doors, telescopic sliding doors, and horizontal-axis swinging leaf doors. Among them, the biggest defect of flapping doors and sliding doors is that they cannot be retracted automatically when the power is off, which is not conducive to emergency flow of people. Howe...
