Description

Technical Field

[0001] The utility model relates to the technical field of platform shielding doors, in particular to a subway shielding door. Background Art

[0002] Subway screen doors are a high-tech product that integrates architecture, machinery, materials, electronics and information. They are used on subway platforms. Subway is a form of railway transportation, referring to an urban rail transit system that mainly runs underground, namely "underground railway" or "subway". Subway is an urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas, with high density and high transportation volume. With the application of light rail and subway in major cities, subway screen doors are installed on the side of light rail and subway platforms in view of safety and improvement of passenger waiting environment.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN207144756U discloses a subway screen door, including a support rod and a motor cover, the bottom of the inner cavity of the motor cover is fixedly connected to a motor, the inner cavity of the support rod is movably installed with a rotating shaft, the outer surface of the rotating shaft is movably connected to a door panel through a connecting rod, a reserved groove is provided on the right side of the inner cavity of the door panel, a blocking rod is movably connected to the left side of the inner cavity of the reserved groove through a spring, and a belt pulley is sleeved on the lower end of the outer surface of the rotating shaft. The utility model has an alcohol sensor and a heart rate sensor fixedly connected to the outer surface of the support rod from top to bottom in sequence, and through the function of the display and the alarm, people can place their fingers on the heart rate sensor or blow towards the alcohol sensor. The heart rate sensor and the alcohol sensor detect people's heart rate and the alcohol concentration in the exhaled gas, and when the heart rate exceeds the maximum preset value and the alcohol concentration is higher than the maximum preset value, the alarm sounds an alarm, thereby ensuring the safety of people riding.
